Observational-Dx 34 cadaver fingers from 10 body donors To determine the specific positioning of each pulley with regards to the joint, and to evaluate the ultrasound diagnostics of various pulley rupture combinations. Visualization of the A2 and A4 pulleys was achieved 100% of the time, while the A3 pulley was visible in 74% of cases. Similarly, injuries to the A2 and A4 pulleys were readily observable, while A3 pulley injuries were more challenging to identify (sensitivity of 0.2 for singular A3 pulley, 0.5 for A2/A4 pulley and 0.33 for A3/A4 pulley ruptures). Receiver operating characteristic analysis was used to evaluate the optimal tendon-bone distance for pulley rupture diagnosis, a threshold which was determined to be 1.9 mm for A2 pulley ruptures and 1.85 for A4 pulley ruptures. 3

In 96 of 126 (76%) examinations, sonography proved to be contributive, and in 30 of 126 (24%) examinations, sonography proved to be noncontributive. The contributive/noncontributive ratio was 3.2 (96/30). A total of 51 of 126 (40%) examinations were performed in patients with a history of previous trauma. Sonography proved to be significantly more contributive in a posttraumatic setting (chi-square, 9.2; P = .0023). 4
18. Dietrich TJ, Toms AP, Cerezal L, et al. Interdisciplinary consensus statements on imaging of scapholunate joint instability. Eur Radiol. 31(12):9446-9458, 2021 Dec. Review/Other-Dx N/A To establish evidence-based consensus statements on imaging of scapholunate joint (SLJ) instability by an expert group using the Delphi technique. Ten of fifteen statements achieved group consensus in the second Delphi round. The remaining five statements achieved group consensus in the third Delphi round. It was agreed that dorsopalmar and lateral radiographs should be acquired as routine imaging work-up in patients with suspected SLJ instability. Radiographic stress views and dynamic fluoroscopy allow accurate diagnosis of dynamic SLJ instability. MR arthrography and CT arthrography are accurate for detecting scapholunate interosseous ligament tears and articular cartilage defects. Ultrasonography and MRI can delineate most extrinsic carpal ligaments, although validated scientific evidence on accurate differentiation between partially or completely torn or incompetent ligaments is not available. 4

22. De Filippo M, Pogliacomi F, Bertellini A, et al. MDCT arthrography of the wrist: diagnostic accuracy and indications. Eur J Radiol. 2010;74(1):221-225. Observational-Dx 44 wrists To evaluate the diagnostic accuracy and indications of arthrography with Multidetector Computed Tomography (arthro-MDCT) of the wrist in patients with absolute or relative contraindications to magnetic resonance imaging (MRI) studies and in patients with periarticular metal implants using diagnostic arthroscopy as the gold standard. In non-operated and operated wrists the comparison between arthro-MDCT and arthroscopy showed sensitivity, specificity and accuracy ranging between 92% and 94% for triangular fibrocartilage complex (TFCC), between 80% and 100% for intrinsic ligaments located within the proximal carpal compartment, and between 94% and 100% for articular cartilage. Inter-observer agreement between two radiologists, in the evaluation of all types of lesions, was almost perfect (k=0.96) and statistically significant (p<0.05). Arthro-MDCT of the wrist provides an accurate diagnosis to identify chondral, fibrocartilaginous and intra-articular ligament lesions in patients who cannot be evaluated by MRI, and in post-surgical patients. 3

Observational-Dx 46 participants with 92 wrist To evaluate inter- and intraobserver agreement and normal ranges of CT scoring methods for determination of DRUJ translation in both posttraumatic and uninjured wrists. Interobserver agreement was best for the epicenter method [ICC?=?0.73, 95 % confidence interval (CI) 0.65–0.79]. Intraobserver agreement was almost perfect for the radioulnar line method (ICC?=?0.82, 95 % CI 0.77–0.87). Each method showed a wide normal range for normal DRUJ translation. Normal range for the epicenter method is -0.35 to -0.06 in pronation and -0.11 to 0.19 in supination. 2

J Hand Surg [Am]. 41(1):59-69, 2016 Jan. Observational-Dx 22 men To present results regarding the accuracy of the reduction of surgically reconstructed scaphoid nonunions or fractures using 3-dimensional computer-based planning with and without patient-specific guides. In group 1, 8 of 9 scaphoids healed after 2 to 6 months, and partial nonunion after 9 months was observed in one patient. In group 2, 11 of 13 scaphoids healed between 2 and 34 months whereas 2 scaphoids did not consolidate. Comparison of the preoperative and postoperative 3-dimensional data revealed an average residual displacement of 7° (4° in flexion-extension, 4° in ulnar-radial deviation, and 3° in pronation-supination) in group 1. In group 2, residual displacement after surgery was 26° (22° in flexion-extension, 12° in ulnar-radial deviation, and 7° in pronation-supination). 3

J Magn Reson Imaging. 1999;9(3):468-474. Observational-Dx 35 patients To assess the value of three-compartment magnetic resonance (MR) wrist arthrography in comparison with non-enhanced magnetic resonance imaging (MRI) for the evaluation of 13 individual wrist ligaments. The delineation of individual wrist ligaments was rated as "good" in 10% of non-enhanced MR and 90% of MR arthrography images. Ligament evaluation was possible with high diagnostic confidence in 11% by non-enhanced MR imaging and 90% by MR arthrography. With wrist arthroscopy as the standard of reference, average sensitivities/specificities/accuracies for the diagnosis of full-thickness ligamentous defects were 0.81/0.75/0.77 for non-enhanced MR imaging and 0.97/0.96/0.96 for MR arthrography. The findings suggest that MR arthrography is more accurate than standard MRI in delineating and evaluating the ligaments of the wrist. 2

Skeletal Radiol 2013;42:1277-85. Observational-Dx 5 cadavers; 10 wrists To compare the diagnostic performance of multidetector CT arthrography (CTA), conventional 3-T MR and MR arthrography (MRA) in detecting intrinsic ligament and triangular fibrocartilage complex (TFCC) tears of the wrist. Intravenous contrast was administered. Sensitivities/specificity/accuracy of CTA, conventional MRI, and MRA were 100%/100%/100%, 66%/86%/80%, 100%/86%/90% for the detection of SLL tear, 100%/80%/90%, 60%/80%/70%, 100%/80%/90% for the detection of LTL tear, and 100%/100%/100%, 100%/86%/90%, 100%/100%/100% for the detection of TFCC tear. Overall CTA had the highest sensitivity, specificity, and accuracy among the three investigations while MRA performed better than conventional MR. CTA also had the highest sensitivity, specificity, and accuracy for identifying which component of the SLL and LTL was torn. Membranous tears of both SLL and LTL were better visualized than dorsal or volar tears on all three imaging modalities. 3

Acad Radiol. 23(9):1091-103, 2016 09. Meta-analysis 103 conference proceedings, 24 studies To perform a systematic review and meta-analysis for evaluating the diagnostic accuracy of 1.5 Tesla and 3.0 Tesla magnetic resonance imaging (MRI), and magnetic resonance arthrography (MRA), in the detection of scapholunate interosseous ligament (SLIL) injury. Heterogeneity was detected for 1.5 T MRI (chi-square: 47.93, P < 0.001) but not for 3.0 T MRI (chi-square: 8.00, P value: 0.09) and MRA (chi-square: 14.54, P value: 0.34) studies. The sensitivities of 1.5 T MRI, 3.0 T MRI, and MRA for detection of SLIL injury were 45.7% (95% confidence interval: 40.1-51.4), 75.7% (66.8-83.2), and 82.1% (76.1-87.2), respectively. The specificities of 1.5 T MRI, 3.0 T MRI, and MRA for detection of SLIL injury were 80.5% (77.3-83.4), 97.1% (89.8-99.6), and 92.8% (90.2-94.9), respectively. The diagnostic odds ratios of 1.5 T MRI, 3.0 T MRI, and MRA for detection of SLIL injury were 5.56 (2.71-11.39), 23.23 (3.16-171.00), and 65.04 (32.89-128.62) (P value < 0.001), respectively. The results were consistent after addressing publication bias and sensitivity analyses. Good

Wrist Traction During MR Arthrography Improves Detection of Triangular Fibrocartilage Complex and Intrinsic Ligament Tears and Visibility of Articular Cartilage. AJR Am J Roentgenol. 206(1):155-61, 2016 Jan. Observational-Dx 40 wrists in 39 patients To assess the effects of traction during MR arthrography of the wrist on joint space widening, cartilage visibility, and detection of tears of the triangular fibrocartilage complex (TFCC) and intrinsic ligaments. With traction, all joint spaces in the wrist and carpus were significantly widened (change, 0.15-1.01 mm; all p < 0.006). Subjective cartilage visibility of all joint spaces improved after traction (all p = 0.048) except for that of the radioscaphoid space, which was well visualized even before traction. Conventional arthrography depicted 24 TFCC tears, seven LTL tears, and three SLL tears. The accuracy of tear detection improved after traction for the TFCC (98% after traction vs 83% before traction), the LTL (100% vs 88%), and the SLL (100% vs 95%). Tear visibility improved after traction for 54% of TFCC tears, 71% of LTL tears, and 66% of SLL tears. 2

Observational-Dx 34 patients; 2 blinded observers Retrospective study to determine if preoperative IV-contrast-enhanced MRI can distinguish between ganglion (including occult dorsal ganglia) and synovitis in chronic wrist pain. MRI accurate in preoperative differentiation of ganglion vs synovitis in chronic dorsal wrist pain; four main radiographs criteria useful—margin, shape, internal structure, and enhancement, with shape and internal structure most helpful. For ganglia, MR sensitivity = 89-94%; specificity = 85-95%. 3

J Hand Surg Am. 2008;33(7):1153-1159. Observational-Dx 102 patients To evaluate the diagnostic comparison of 1.5 Tesla and 3.0 Tesla preoperative MRI of the wrist in patients with ulnar-sided wrist pain. A tear of the TFCC was identified retrospectively on 1.5T images in 49 of 58 patients and on 3.0T images in 15 of 16 patients. Compared with the gold standard of arthroscopy, 1.5T wrist MRI in this patient population had a sensitivity of 85%, a specificity of 75%, and an accuracy of 83% for reader 1 for the detection of a tear of the TFCC. In the same patient population, 3.0T wrist MRI had a sensitivity of 94%, a specificity of 88%, and an accuracy of 91% for reader 1. For reader 2, the improvement in sensitivity for the lunotriquetral ligament between the 1.5T and 3.0T images was statistically significant. The sensitivity, specificity, and accuracy of 3.0T wrist MRI for the TFCC is consistently higher compared with those of 1.5T wrist MRI. The trend suggests that 3.0T wrist MRI provides improved capability for detection of TFCC injuries. Given the available sample size, however, the confidence intervals around the point estimates are wide and overlapping. Further studies are needed to confirm or refute our results of the estimated sensitivity, specificity, and accuracy parameters. 2

Arch Orthop Trauma Surg. 137(10):1443-1450, 2017 Oct. Observational-Dx 18 patients To assess the sensitivity and specificity of 3T MRI compared with arthroscopy as the gold standard. The classifications of the cartilage lesions showed good correlations with the arthroscopy findings (? = 0.8-0.9). In contrast to the arthroscopy, cartilage of the distal carpal row was very good and could be evaluated in all patients on MRI. The sensitivity for the TFCC lesion was 83%, and the specificity was 42% (radiologist 1) and 63% (radiologist 2). For the ligament lesions, the sensitivity and specificity were 75 and 100%, respectively, with a high interobserver agreement (? = 0.8-0.9). 3

Skeletal Radiology. 49(10):1567-1579, 2020 Oct. Observational-Dx 67 patients To investigate the MR features of the traumatic injury of the triangular fibrocartilage complex (TFCC) by using high-resolution 3-T magnetic resonance imaging (MRI) and to refine the Palmer classification system. There were 49 cases of TFCC injuries proven by the arthroscopy or surgery. The TFCC injuries in the other 18 patients were proved by the combination of clinical follow-up examination and follow-up MRI. Among the arthroscopy- or surgery-confirmed cases, there were 32 patients with original Palmer injuries (IA = 10, IB = 19, ID = 3), 5 with capsular detachment, 4 with bucket-handle tear of the TFCC that have rarely been reported, and 8 with complex injuries that involved the listed classifications above. The sensitivities and specificities of MRI for diagnosing IA, IB, ID, complex injuries, and bucket-handle tear were 67-100% and 90-100%, and overall good to perfect interobserver agreements (kappa, 0.64-1.00).

Review/Other-Dx 318 consecutive images from 316 patients To describe an outcome analysis of the utility of MRI in a cohort of patients treated in our hand surgery clinic. Ganglions (28%), findings on the extensor carpi ulnaris tendon (18%) and on the triangular fibrocartilage (18%) were the most common findings and increased with patient age; the clinical significance of these findings was minimal. The correlation between the clinical scaphoid shift test or the fovea sign test and MRI was also non-significant. Despite findings on MRI, the diagnosis remained unsolved in 76 (24%) cases. However, MRI had a role in reassuring the patient, and in 70% of the cases, further follow-up was unnecessary. 4

Review/Other-Dx 9 patients To use ultrasound to examine the dorsal hood in nine patients with a clinical suspicion of dorsal hood injuries. The sagittal bands were easily depicted in the transverse plane on ultrasound images and presented as hypoechoic bands on both sides of the extensor communis tendons. Injuries of the sagittal bands were seen on ultrasound as hypoechoic thickening of the sagittal bands at the side of the extensor tendons. The normal shape of the sagittal bands was also no longer recognizable. Subluxations or dislocations of the extensor tendons were also seen. When the injuries were located in the fibrous slips between the extensor indicis and the extensor communis of the second finger, subluxations with an increased distance between these 2 tendons were seen, especially in flexion, or in flexion with resistance. 4

Review/Other-Dx 85 patients To investigate determinants of decrease and increase in joint pain in symptomatic finger osteoarthritis (OA) on magnetic resonance (MR) imaging over 2 years. Of 116 painful joints at baseline, at follow-up: 76 had less pain, 21 less synovitis, and 13 less BMLs. A decrease in synovitis (OR = 5.9; 1.12-31.0), but not in BMLs (OR = 0.39; 0.10-1.50), was associated with less pain. Of 678 joints without maximum baseline pain, at follow-up: 115 had increased pain, 132 increased synovitis, 96 increased BMLs, and 44 increased osteophytes. Increased synovitis (OR = 1.81; 1.11-2.94), osteophytes (OR = 2.75; 1.59-4.8), but not BMLs (OR = 1.14; 0.81-1.60), was associated with increased pain. 4

Observational-Dx 11 female patients To apply the recently proposed Oslo hand osteoarthritis magnetic resonance imaging (MRI) scoring system to evaluate MRI findings in a cohort of patients affected by long-standing erosive hand osteoarthritis (EHOA). Spearman's non-parametric test was used to analyze the correlations between variables. MRI intra- and inter-reader reliability were found between good and moderate for many features. No statistical differences were found between the radiographs and MRI with regard to detection of JSN, malalignment, and bone erosions. Synovitis was detected in 39.8 % of the 80 joints examined (in a mild form in 80 %), erosions were found in 51.1 %, and BMLs were identified in 20.5 and 23.9 % at the distal and the proximal side, respectively. BMLs at both the proximal and distal ends were correlated with tender joints (BML distal p = 0.0013, BML proximal p = 0.012). The presence of synovitis was correlated with tenderness (p = 0.004) and erosions at both the distal and proximal joints (p = 0.004). The presence of erosions correlated with tender joints (p < 0.01) and the mean visual analog scale (VAS) score (distal p = 0.03, proximal p = 0.01). 3

To evaluate and compare conventional magnetic resonance (MR) imaging and MR arthrography in the diagnosis of the most common traumatic metacarpophalangeal (MCP) joint injuries, which were created surgically in cadavers. Sensitivity was 28.6%-93.8% with conventional MR imaging versus 50.0%-93.3% with MR arthrography. Specificity was 66.7%-100% with conventional MR imaging versus 83.3%-100% with MR arthrography. Although the MR arthrographic results usually were higher, the differences were not significant. The kappa values for interobserver agreement were 0.314-0.638 for conventional MR imaging versus 0.364-1.00 for MR arthrography. Sensitivity for the detection of lesions of the main and accessory CLs and the first annular pulley was slightly higher than that for the detection of lesions of the extensor hood, DTML, and palmar plate structures. 3

Review/Other-Dx 68 patients To report patterns of MRI findings involving carpal boss and extensor carpi radialis brevis (ECRB) tendon insertion in individuals with overuse-related or post-traumatic wrist pain. Fused carpal bossing was detected in 21%, partial coalition in 35%, and os styloideum in 44% of the cases. Regional BME was observed in 64% of the cases. When BME specifically at the carpal boss was assessed, 78% of stable and 50% of unstable bosses showed BME (p = 0.035). ECRB tendon inserted on a carpal boss in 20%, on the 3rd metacarpal bone in 35%, and on both sites in 45% of the cases. As BME at the carpal boss was assessed, BME was detected at the respective insertion sites in 71%, 35%, and 66% of the cases (p = 0.015). Dorsal wrist pain was associated with BME as 75% of the patients had regional BME in the vicinity of the carpal boss (p = 0.006). 4

Review/Other-Dx 165 patients To investigate the two-year course of pain and osteoarthritic features on magnetic resonance imaging (MRI) in the thumb base. At baseline, 65 patients had thumb base pain. At 2-year follow-up, pain had decreased in 32 patients and increased in 33 patients. MRI features remained stable in most patients. Structural MRI features generally deteriorated, while synovitis and BMLs improved in some individuals and deteriorated in others. Change in radiographic osteophytes rarely occurred (n = 10). Increased synovitis (odds ratio [OR] 3.4 [95% CI 1.3-9.3]) and increased BMLs (OR 5.1 [95% CI 2.1-12.6]) were associated with increased pain. Decreased BMLs appeared to be associated with decreased pain (OR 2.7 [95% CI 0.8-8.9]), and reductions in synovitis occurred too infrequently to calculate associations. 4

Observational-Dx 56 consecutive patients (56 thumbs) To assess the accuracy of MRI in identifying ulnar collateral ligament (UCL), radial collateral ligament (RCL), and volar plate (VP) injuries of the metacarpophalangeal joint (MCPJ) of the thumb by comparing with diagnostic arthroscopy. The sensitivity, specificity and accuracy of MRI for detecting UCL injuries were 78.8%, 87.0%, and 82.1%, respectively. The sensitivity, specificity and accuracy of MRI for detecting RCL injuries were 85.7%, 91.4%, and 85.7%, respectively. The sensitivity, specificity, and accuracy of MRI for detecting VP injuries were 89.5%, 89.2%, and 81.0%, respectively. 3.0-tesla MRI showed higher correspondence with arthroscopic observation (76.9%) than 1.5-tesla MRI (47.1%) (p = 0.028). For acute injuries, 78.4% showed complete correspondence between MRI and arthroscopic findings, whereas 47.4% with chronic injuries revealed complete agreement (p = 0.019). 2

Observational-Dx 19 patients To evaluate the validity of contrast enhanced dual energy CT using a lung perfusion algorithm in assessing for post-traumatic scaphoid proximal pole avascular necrosis. Eight surgical specimens were sent to histology and showed a 100% correlation (8/8) with the DECT findings. The remaining 11 wrists that did not have a specimen sent had in-surgery findings that also correlated with DECT. A single case was discrepant (1/11) due to presence of an intra-osseous ganglion, which was reported as osteonecrosis on CT, but considered viable at surgery. No case was called viable on CT that proved to be necrotic at either surgery or histologically. 4

Observational-Dx 45 patients, 12 phantom for contrast selection 2 observers In vitro and in vivo study to evaluate MRI and combination of MDCT arthrography and MR arthrography (one injection) for diagnosis of wrist ligament tears and cartilage abnormalities, with clinical and operative follow-up. Complete SL and LT tears defined as involving all 3 (dorsal, central, volar) segments; partial defined as involving 1 or 2 segments. Sensitivity and specificity calculated for multiple anatomic sites (SL, LT, TFCC) and observers, with SL and LT ligaments evaluated equally well by all three techniques; however, CT arthrography best for partial tears (SL, LT), TFCC tears, and cartilage abnormalities, and statistically significantly better than MRI; MR arthrography more sensitive than MRI but not statistically significant. Sensitivity: CTA > MRA > MRI, especially for articular cartilage defects, ulnar-sided TFCC tears, and partial SL and LT ligament tears. 1

Radiology. 2007;243(1):180-187. Observational-Dx 10 cadaveric wrists from 9 subjects To evaluate prospectively the diagnostic accuracy of MR imaging in the identification of cartilage abnormalities at 3.0 and 1.5 T in cadaveric wrists, with gross pathologic findings as the standard of reference. 170 cartilage surfaces were graded. The sensitivity and specificity for cartilage lesions were 43%-52% and 82%-89%, respectively, at 1.5 T and 48%-52% and 82% at 3.0 T. Differences in assessment did not reach statistical significance (P > .99). Highest sensitivities were found in the proximal carpal row (67%-71%); lowest sensitivities were found in the distal carpal row (14%-24%). Interobserver agreement was higher for imaging at 3.0 T (kappa = 0.634) than at 1.5 T (kappa = 0.267). The performance of MR imaging for the detection of articular cartilage abnormalities in the wrist depends on anatomic location. Interobserver agreement is higher for imaging at 3.0 than at 1.5 T, but diagnostic performances were not significantly different (P > .99) at either field strength. 2

AJR Am J Roentgenol 2000;174:141-9. Observational-Dx 30 consecutive patients To identify the role of gadolinium-enhanced MR imaging in the preoperative evaluation of the vascular status of the proximal fragment in scaphoid nonunions. Unenhanced MR imaging showed a global sensitivity of 36%, specificity of 78%, and accuracy of 68% in the preoperative evaluation of the vascular status of the proximal fragment. Correlation with the surgical findings was not statistically significant (p < 0.149). Global sensitivity, specificity, and accuracy of gadolinium-enhanced MR imaging were 66%, 88%, and 83%, respectively. Correlation with the surgical findings was good (p < 0.0001). Gadolinium-enhanced sequences allowed accurate diagnosis and enabled the creation of prognostic groups having better correlation with surgical findings and postoperative results. Gadolinium-enhanced MR imaging is the most reliable imaging method for investigating the vascularity of the proximal pole in scaphoid nonunions. 2

Observational-Dx 29 patients To evaluate the accuracy of unenhanced T1-weighted MR images in predicting the vascular status of the proximal pole of the scaphoid in patients with chronic scaphoid fracture nonunions. Unenhanced MRI had a sensitivity, specificity, and accuracy of 55%, 94%, and 79%, respectively, for diagnosing AVN. Increased proximal pole STIR signal was noted with similar frequencies in patients with and without AVN. T1-weighted unenhanced MRI is an acceptable alternative to delayed contrast-enhanced MRI in the preoperative assessment of the vascular status of the proximal pole of the scaphoid in patients with chronic fracture nonunions. STIR images were not beneficial in determining proximal pole viability. 2

Meta-analysis 13 studies To review and pool recent large methodological studies evaluating the diagnosis performance of ultrasonography vs electrodiagnostic testing (EDX). Among the 189 articles found, 13 articles were included. A cross-sectional area of the median nerve between 9.5 and 10.5 mm(2) (study included once only), found for 11 studies, gave the pooled sensitivity as 0.84 [0.81 to 0.87] and the likelihood ratio for a negative test as 0.21 [0.17 to 0.27]. Specificity (0.78 [0.69-0.88]) and the likelihood ratio for a positive test (3.74 [2.30-6.10]) were heterogeneous. For a threshold at 7.0 to 8.5 mm(2), pooled sensitivity was 0.94 [0.87 to 1.00], and for 11.5 to 13.0 mm(2) specificity was 0.97 [0.91 to 1.00]. The only significant variable on potential sources of heterogeneity was the cross-sectional area of the median nerve threshold and area under the curve was 0.87 (asymmetric). M

Review/Other-Dx 17 studies To analyze and summarize recent published data evaluating measurement properties of diagnostic ultrasound for use in individuals with CTS. Measurements of median nerve cross sectional area (CSA) taken at the carpal tunnel inlet consistently demonstrated good to excellent interrater reliability (ICC=0.83-0.93) and good intrarater reliability (r>0.81). All studies supported inlet CSA in differentiating between individuals with and without CTS. Carpal tunnel inlet CSA measurements demonstrated a moderate correlation to the Padua severity classification (r = 0.71), but this varied between studies. Diagnostic accuracy of CSA measured at the carpal tunnel inlet using diagnostic cutoff values ranging from 8.5 mm2 to 12.6 mm2 resulted in a range sensitivity (63%-96.9%) and specificity (67.9%-100%). 4

J. hand surg., Eur. vol.. 47(4):369-374, 2022 04. Observational-Dx 77 patients and 47 controls. To evaluate the usefulness of ultrasonography in diagnosing carpal tunnel syndrome (CTS). A significant correlation was found between the ultrasonography cross-sectional area values at entry points into the carpal tunnel and electroneuromyography. The highest sensitivity (87%) and specificity (91%) for different cut-off values (8.5-12.5 mm2) of the cross-sectional area was for 11.5 mm2. 3
74. Sears ED, Lu YT, Wood SM, et al. Diagnostic Testing Requested Before Surgical Evaluation for Carpal Tunnel Syndrome. J Hand Surg [Am]. 42(8):623-629.e1, 2017 Aug. Review/Other-Dx 134 providers To evaluate how often physicians who perform carpal tunnel release in the state of Michigan routinely request electrodiagnostic studies (EDS) or other diagnostic tests prior to an initial consultation and whether provider or practice characteristics had an influence on requirements for preconsultation diagnostic tests. Among the 134 providers who were confirmed to perform carpal tunnel release, 57% (n = 76) required and 9% (n = 12) recommended a diagnostic test prior to the initial consultation. Of the 88 physicians who required/recommended testing, 85% (n = 75) requested EDS, 22% (n = 19) requested magnetic resonance imaging, 13% (n = 11) requested a computed tomography scan, and 9% (n = 8) requested an x-ray. Patients were asked to have multiple studies by 19 (22%) of the 88 surgeons who requested/recommended testing. 4

Observational-Dx 30 patients (72 exams) To describe the appearance of tenosynovitis in various tendon groups in the wrist and hand and to compare MR enhanced and non-enhanced imaging evaluation of tenosynovitis of hand and wrist in inflammatory arthritis. The average T2 brightness scores and post-gadolinium enhancement scores were 1.0 and 1.7, respectively (P<0.001) in the wrist studies. The average T2 brightness scores and post-gadolinium enhancement scores were 0.7 and 1.4, respectively (P<0.001) in the hand studies. The average sensitivity of T2-weighted imaging for detection of tenosynovitis was 40% in the hand and 67% in the wrist tendons, when contrast-enhanced images were used as a reference. Carpal tunnel flexor tendons were the most frequently affected tendons of the wrist. The most frequently affected tendons of the hand were second and third flexor tendons. The hand flexors demonstrated higher degrees of enhancement and larger volumes of the inflamed tenosynovium than did the hand extensors and tendons of the thumb. 3

J Ultrasound Med. 37(4):941-948, 2018 Apr. Observational-Dx 8 cadaveric specimens To evaluate ultrasonographic test characteristics and accuracy in identifying partial flexor tendon lacerations in a cadaveric model. The sensitivity and specificity in detecting the presence versus absence of a partial laceration were 0.54 and 0.75, respectively, with positive and negative likelihood ratio values of 2.17 and 0.61. For low-grade lacerations, the sensitivity and specificity were 0.25 and 0.85, compared to 0.83 and 0.85 for high-grade lacerations. Ultrasonography underestimated the percentage of tendon involvement by a mean of 18.1% for the study population as a whole (95% confidence interval, 9.0% to 27.2%; P < .001) but accurately determined the extent for correctly diagnosed high-grade lacerations (-6.7%; 95% confidence interval, -18.7% to 5.2%; P = .22). 1

Observational-Dx 40 patients To evaluate the accuracy of sonography for identifying the intracompartmental septum in the first extensor compartment in patients with de Quervain's disease using surgical findings as the reference standard Sonography identified the intracompartmental septum in 19 of the 19 septum-present wrists and absence of the septum in 23 of the 24 septum-absent wrists. The sensitivity of sonography was 100% (95% confidence interval, 80%-100%), its specificity 96% (95% confidence interval, 78%-100%), accuracy 98% (95% confidence interval, 87%-100%), positive predictive value 95% (95% confidence interval, 74%-100%), and negative predictive value 100% (95% confidence interval, 83%-100%). Sonography also identified septum-like structures in 15 of 37 (41%) asymptomatic contralateral wrists. Sonography is useful for detecting the intracompartmental septum in the first extensor compartment in patients with de Quervain's disease. 3

Observational-Dx 35 patients with penetrating trauma To validate the diagnostic accuracy of ultrasound (US) scans in pre-operative evaluation of flexor tendon injuries in the hand and to determine its value in the management of such injuries and in the prediction of patient outcome. Ultrasound results were compared with the operative findings as the gold standard test. Patients were followed up postoperatively, and functional outcome was assessed and correlated with pre-operative sonographic findings. Our results indicate that sonographic examination of hand tendon injury has high accuracy in diagnosing complete or partial flexor injuries, with 100% accuracy, sensitivity and specificity in diagnosing full-thickness tears as well as tenosynovitis of hand flexor tendons. Zonal II injury was the most frequent among our study population and correlated with poorest functional outcome after rehabilitation at 3 mo follow-up. 2
