No evidence for the superiority of 3 T MRI over 1.5 T MRI for diagnosing wrist ligamentous lesions: a systematic review and meta-analysis. Arthroscopy 2024:S0749-8063(24)00335-9. [PMID: 38735416 DOI: 10.1016/j.arthro.2024.04.029] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/04/2023] [Revised: 04/17/2024] [Accepted: 04/18/2024] [Indexed: 05/14/2024]
Abstract
PURPOSES Our aim was to determine the diagnostic accuracy of native MRI regarding different ligamentous lesions of the wrist and to analyze the influence of technical characteristics, such as field strength, application of fat saturation, 3D sequences, and wrist coils. METHODS The systematic search was performed using MEDLINE, Embase, and CENTRAL databases. Studies that were published before the 12th of February 2024 were included. All studies comparing the diagnostic accuracy of native wrist MRI to that of wrist arthroscopy for suspected ligamentous lesions were included. Results were analyzed by anatomic localization and technical aspects of the MRI. To assess the quality of included studies, we used the revised QUADAS-2 tool. RESULTS The systematic search revealed 5,181 articles. Thirty-seven studies, reporting 3893 ligamentous lesions, were eligible for inclusion. The studies displayed heterogeneity in terms of technical conditions, such as field strength, the use of wrist coils, the application of 3D sequences and fat saturation. Research methods also varied. Overall sensitivity and specificity were 0.78 (0.66 - 0.86) and 0.81 (0.70 - 0.89) for 1.5T MRI, while sensitivity was 0.73 (0.68 - 0.78) and specificity was 0.90 (0.59 - 0.98) for 3T MRI. There was no significant difference between the two subgroups (p=0,3807 and p=0,4248). Sensitivity was 0.82 (0.75 - 0.87) for triangular fibrocartilage complex (TFCC) lesions, 0.63 (0.50 - 0.74) for scapholunate ligament (SL) tears, and 0.41 (0.25 - 0.60) for lunotriquetral ligament (LT) lesions. Specificity for TFCC lesions was 0.82 (0.73 - 0.89), for SL tears 0.86 (0.73 - 0.93), and for LT lesions 0.93 (0.81 - 0.98). CONCLUSION The sensitivity and specificity of MRI is influenced by the anatomic location of the lesion and technical conditions. In terms of diagnostic accuracy, no significant difference was found between 1.5T and 3T MRI. LEVEL OF EVIDENCE III. Systematic review of Level II. - III. STUDIES

Abstract
INTRODUCTION While multiple ulnar-sided wrist pain (USWP) diagnostic evaluation guides have been presented, none have included original clinical data or statistical analysis. The purpose of this study is to provide a diagnostic evaluation guide derived from original clinical data and analysis to help clinicians arrive at a differential diagnosis for USWP. METHODS Using a computer search of patients presenting with sprains, instability, and laxity of the wrist, 385 patient charts were identified. Patient demographics, mechanism of injury, subjective complaints, physical findings, and diagnostic test findings were reviewed. Statistical analysis was performed to determine sensitivity and specificity of diagnostic methods on their ability to identify lunotriquetral ligament tears, triangular fibrocartilage complex (TFCC) tears, and ulnar impaction syndrome. Diagnostic arthroscopy was used as the reference standard. RESULTS Ninety-three patients, comprising 101 cases of USWP, were included in the study. The onset of injury was traumatic in 83 out of 101 cases with motor vehicle accidents (N=46) being the most common, followed by overuse (N=18), and a fall onto an outstretched hand (N=16). The ulnocarpal tenderness test exhibited sensitivity/specificity of 72%/33%; lunotriquetral ligament laxity test of 42%/62%; bone scan of 80%/33%; radiocarpal arthrogram of 90%/98% for TFCC tears and 50%/91% for lunotriquetral ligament tears; midcarpal arthrogram of 82%/86% for lunotriquetral ligament tears. The mean ulnar variance on standard posteroanterior view radiograph was 0.95 mm, increasing to 2.67 mm on gripping posteroanterior view. CONCLUSION Physicians should suspect a lunotriquetral ligament and/or TFCC tear with the acute onset of USWP following a loaded dorsiflexed mechanism of injury. Ulnocarpal tenderness tests and pre-operative ulnar variance measures are effective for increasing suspicion of USW pathology. Bone scans are helpful in diagnosing ulnar impaction syndrome in conjunction with radiographic findings. A combination of midcarpal arthrogram for lunotriquetral ligament tears and radiocarpal arthrogram for TFCC tears should be employed.

Abstract
Purpose To determine the outcomes of diagnostic and therapeutic arthroscopy in patients with chronic wrist pain who are younger than 16 years of age. Methods We retrospectively analyzed collected data from medical records of patients who had undergone wrist arthroscopy by the senior author between 2015 and 2017 for longstanding wrist pain and were 16 years old or younger. Findings from preoperative magnetic resonance imaging (MRI) were compared with the intraoperative diagnosis, and midterm results were gathered by a telephone interview. Results Ten patients were included. Eight of 10 patients had undergone conservative therapy before surgery, and 60% had a history of single trauma. In 6 of 10 patients, the arthroscopic diagnosis correlated with the MRI findings. Eight of 10 wrists (80%) showed a tear of the triangular fibrocartilage complex (TFCC). Only 4 of the 8 TFCC tears were correctly identified by 3-Tesla MRI. Conclusions In our study, wrist arthroscopy was an effective tool not only to diagnose but also to treat relevant TFCC lesions both in adolescents and children suffering from persistent wrist pain. A 3-Tesla MRI was neither sensitive nor specific enough to correctly diagnose lesions in small pediatric wrists. Level of Evidence IV, Therapeutic case series.

Abstract
Background Triangular fibrocartilage complex (TFCC) injury is common in distal radius fractures. The purpose of this study was to compare the conservative and surgical treatments of TFCC injury of the wrist associated with distal radius fractures. Methods A retrospective study was conducted on 39 patients who received treatment for TFCC injury with distal radius fractures. All patients were treated using a volar locking plate for distal radius fractures. Twenty-six patients who received conservative treatment for TFCC through long arm splinting were classified into group 1, and 13 patients who received surgical treatment for TFCC were classified into group 2. The splint was maintained for 6 weeks in both groups. For clinical evaluation, the range of motion (ROM) of the wrist joint, patient-rated wrist evaluation (PRWE) score, Disabilities of the Arm, Shoulder and Hand (DASH) score, and grip strength were measured. Distal radioulnar joint (DRUJ) stability was evaluated through a stress load test and graded between grade 0 and 3 intraoperatively after fixation and at the final follow-up. Results In group 1, the average DASH score was 11.1 ± 4.4, the average PRWE score was 10.2 ± 4.6, the grip strength was 89.4% relative to the unaffected side, the average ROM of the wrist joint was 65° ± 7.0° for extension, 51.5° ± 8.1° for flexion, 86° ± 5.1° for supination, and 85° ± 5.2° for pronation, and DRUJ stability at the final follow-up was grade 0 in 58.62%, grade 1 in 31.03%, grade 2 in 10.34%, and grade 3 in 0%. In group 2, the average DASH score was 13 ± 5.0, the average PRWE score was 12.4 ± 3.7, the grip strength was 87.3% relative to the unaffected side, and the average ROM of the wrist joint was 60° ± 9.8° for extension, 53.1° ± 7.0° for flexion, 85° ± 5.3° for supination, and 86.8° ± 4.5° for pronation. At the final follow-up, DRUJ stability was grade 0 in 66.67%, grade 1 in 25%, grade 2 in 8.3%, and grade 3 in 0%. The 2 groups showed no statistically significant differences in DASH score, PREW score, grip strength, ROM, and final follow-up DRUJ stability. Conclusions There were no statistically significant differences in the clinical outcomes between the surgical and conservative treatment groups. Therefore, when normal radiological indices are achieved after treatment of distal radius fractures, DRUJ stability can be obtained by conservative treatment.

Abstract
PURPOSE The triangular fibrocartilage complex is one of the most important stabilizers of the wrist and a defect in its anatomical structure is a possible cause of ulnar sided wrist pain. The aim of this study is to compare the diagnostic accuracy between conventional MRI and MR arthrography (MRA) in the depiction of triangular fibrocartilage complex (TFCC) tears. METHODS-MATERIALS A total of 60 patients with clinical findings that suggested TFCC tears underwent wrist MRI and MRA. All the MRI and MRA results were compared with the arthroscopic findings. RESULTS 40 tears were confirmed by arthroscopy. 38/40 tears were identified by MRA while MRI identified 26/40 tears. There were also 8 false positives and 13 false negative results identified by MRI. Two false negative results were identified by MRA. No false positive results were identified. CONCLUSION MR arthrography is more sensitive and specific method in terms of the diagnosis of TFCC tears compared to conventional wrist MRI. There was no difference in the diagnostic accuracy between wrist arthroscopy and MRA.

Abstract
Purpose Changes in the shape of the triangular fibrocartilage complex (TFCC) during radial-ulnar deviation were studied using "cine-mode" magnetic resonance imaging (MRI) in 10 right wrists of healthy volunteers, 5 wrists of TFCC tear, and 5 wrists of ulnar styloid nonunion. Subjects and Methods The wrist was fixed in a custom acrylic device, which only allows radial and ulnar deviation. Coronal MR images of nine radial-ulnar deviated positions (every 5 degree from 15 degrees radial deviation to 25 degrees ulnar deviation) were obtained in volunteers and patients. Cine-mode MRI was assembled and was output to MPEG video to observe. Results Cine MRI demonstrated the ulnar side of the TFCC was elongated by average 15 mm in 15 degrees of radial deviation and shortened by average 8 mm in 25 degrees of ulnar deviation in all normal TFCC subjects. Distal portion of the triangular fibrocartilage (TFC) was compressed during radial-ulnar deviation in 10 healthy volunteers and in 3 patients, but proximal portion of the TFC was stable throughout the motion. In contrast, the wavy deformities on the disc in ulnar deviation were observed in three patients with horizontal tear inside the TFCC. In nonunion of the ulnar styloid process, the fragment was snapped in maximum ulnar deviated position or elongation of the space between the styloid fragment and ulna was seen. Conclusion This study indicated normal and abnormal changes in the shape of the TFCC during radial-ulnar deviation motion on cine MRI. The abnormal dynamic changes of the TFCC may be seen in ulnar deviated position in patients, which are related to positive ulnocarpal stress test with the wrist forced ulnar deviated.

Abstract
Background Imaging of the triangular fibrocartilaginous complex (TFCC) remains difficult, as no single imaging modality demonstrates perfect sensitivity and specificity. Purpose This study performs a meta-analysis of multiple previous publications to guide noninvasive imaging selection for the diagnosis of TFCC injuries. Methods A literature search was performed and conducted. Studies were included that compared the diagnostic accuracy of magnetic resonance imaging (MRI), magnetic resonance arthrography (MRA), and computed tomography (CT)/computed tomographic arthrography (CTA) for the evaluation of TFCC injuries. All studies included either arthroscopic or open surgical findings as the "gold standard." A meta-analysis was performed comparing the diagnostic accuracy of MRA, MRI, and CT for the detection of TFCC injuries. Results Initial search returned 2,568 candidate articles. Studies were then reviewed and narrowed yielding a total of 28 independent studies (20 MRI, 9 MRA, 4 CT/CTA with some studies including multiple modalities) considered in the qualitative data synthesis. Pooling of the raw data in a meta-analysis demonstrated sensitivities of 0.76 (0.72-0.80), 0.78(0.70-0.84), and 0.89 (0.81-0.95) for MRI, MRA, and CT arthrogram, respectively, with specificities of 0.82 (0.77-0.86), 0.85 (0.77-0.92), and 0.89 (0.81-0.95), respectively. Additionally, across all imaging modalities, diagnostic accuracy was highest for central TFCC lesions versus peripheral lesions. Conclusion This study represents the largest meta-analysis to date to compare multiple imaging modalities for the diagnosis of TFCC injuries. Pooled data demonstrated that CTA and MRA had statistically equivalent sensitivity and specificity for the diagnosis of TFCC injuries. Diagnostic accuracy was highest for central TFCC injuries.

Abstract
Introduction In case of clinical suspicion of triangular fibrocartilage complex (TFCC) injury, different imaging techniques are used. The aim of this study was to determine whether MRA is superior to MRI and whether 3.0 T is better than 1.5 T (expresses in sensitivity, specificity and accuracy) in detecting TFCC injury, using arthroscopy as the gold standard. Materials and methods The arthroscopic and MR findings of 150 patients who underwent arthroscopy for ulnar-sided wrist pain between January 2009 and November 2016 were retrospectively reviewed. Results MRA was slightly more accurate compared to conventional MRI, and 1.5 T was slightly more accurate than 3.0 T. 1.5 T wrist MRA had a sensitivity of 80%, a specificity of 100% and accuracy of 90%; 3.0 T wrist MRA 73, 100 and 86%, resp. Conventional 1.5 T wrist MRI had a sensitivity of 71%, a specificity of 75% and accuracy of 73%. For 3.0 T conventional MRI, this was 73, 67 and 70%, resp. Conclusions MRA seems slightly superior to conventional MRI, but one could question whether this difference in diagnostic accuracy outweighs the burden and risks of an invasive procedure for patients with its additional costs. Furthermore, we could not confirm the superiority of 3 T compared to 1.5 T.

Abstract
INTRODUCTION 3T MRI has become increasingly available for better imaging of interosseous ligaments, TFCC, and avascular necrosis compared with 1.5T MRI. This study assesses the sensitivity and specificity of 3T MRI compared with arthroscopy as the gold standard. PATIENTS AND METHODS Eighteen patients were examined with 3T MRI using coronal T1-TSE; PD-FS; and coronal, sagittal, and axial contrast-enhanced T1-FFE-FS sequences. Two musculoskeletal radiologists evaluated the images independently. Patients underwent diagnostic arthroscopy. RESULTS The classifications of the cartilage lesions showed good correlations with the arthroscopy findings (κ = 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 (κ = 0.8-0.9). DISCUSSION 3T MRI proved to be of good value in diagnosing cartilage lesions, especially in the distal carpal row, whereas wrist arthroscopy provided therapeutic options. When evaluating the surgical therapeutical options, 3T MRI is a good diagnostic tool for pre-operatively evaluating the cartilage of the distal carpal row.

Abstract
UNLABELLED We reviewed a series of 50 consecutive wrist arthroscopy patients who had been investigated pre-operatively by direct magnetic resonance arthrography and calculated the sensitivity, specificity, positive predictive value, negative predictive value and overall accuracy of magnetic resonance arthrography in detecting full-thickness triangular fibrocartilage complex tears, intrinsic carpal ligamentous lesions, wrist synovitis and chondral lesions in the radiocarpal joint. The sensitivities of magnetic resonance arthrography in detecting central triangular fibrocartilage complex tears, peripheral triangular fibrocartilage complex tears, scapholunate ligament tears, lunotriquetral ligament tears, dorsal synovitis and radiocarpal chondral lesions were 89%, 63%, 71%, 100%, 32% and 65%, respectively, and its specificities in detecting these lesions were 91%, 98%, 89%, 94% 94% and 97%, respectively. This study suggests that single compartment direct wrist magnetic resonance arthrography can provide high diagnostic accuracy for full-thickness triangular fibrocartilage lesions, intrinsic carpal ligament tears and chondral lesions in the radiocarpal joint, but that it is much less accurate in diagnosing synovitis of the radiocarpal joint.

Abstract
We compared the findings of high-resolution MR imaging and standard MR imaging in the detection of tears of the triangular fibrocartilage in 33 patients with chronic wrist pain on the ulnar side. With arthroscopy as the standard of reference, sensitivity was 100%, specificity 53%, and accuracy 79% with the high-resolution MR imaging, against 83%, 67%, and 76% with the standard MR imaging. High-resolution MR imaging showed a higher sensitivity, but a decreased specificity in the assessment of the triangular fibrocartilage. The results showed that diagnosis of tears in the triangular fibrocartilage by MR imaging, even high-resolution MR imaging, is unsatisfactory, although further technological advances may well improve the accuracy.

Chan JJ, Teunis T, Ring D. Prevalence of triangular fibrocartilage complex abnormalities regardless of symptoms rise with age: systematic review and pooled analysis. Clin Orthop Relat Res 2014; 472:3987-94. [PMID: 25091224 PMCID: PMC4397769 DOI: 10.1007/s11999-014-3825-1] [Citation(s) in RCA: 37] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/11/2014] [Accepted: 07/15/2014] [Indexed: 01/31/2023]
Abstract
BACKGROUND Triangular fibrocartilage complex abnormalities seem to be more common with age, but the degree to which this is so, and the degree to which the presence of an abnormality is associated with symptoms, are topics of controversy. QUESTIONS/PURPOSES We wished to perform a systematic review to determine the prevalence of triangular fibrocartilage complex abnormalities, and to determine if the prevalence of abnormalities are greater with increasing age. In addition, we stratified age groups based on symptoms. METHODS We searched MEDLINE, EMBASE, and the Cochrane Library through August 15, 2013. Studies that reported triangular fibrocartilage complex abnormalities by age were included. Fifteen studies including 977 wrists met our criteria and reported a total of 368 (38%) triangular fibrocartilage complex abnormalities. Eight studies included symptomatic patients; the remainder studied cadavers (six studies) or asymptomatic volunteers (one study). Patients were divided into four age groups (< 30, 30-49, 50-69, and 70 years and older) for pooled analysis, comparing the proportions of patients with and without abnormalities between groups using chi-square analysis. We also evaluated the proportions after stratifying each age group by symptoms. RESULTS Overall, the prevalence of triangular fibrocartilage complex abnormalities increased with age, from 27% (80/301) in patients younger than 30 years to 49% (130/265) in patients 70 years and older (p < 0.001), odds ratio (OR), 2.7, 95% CI, 1.9-3.8 (p < 0.001). In asymptomatic patients, triangular fibrocartilage complex prevalence abnormality increased from 15% (24/159) to 49% (129/263) in the same age groups (p < 0.001), OR, 5.4, 95% CI, 3.3-8.9 (p < 0.001). For symptomatic patients prevalence ranged from 39% (56/142) to 70% (14/20) in patients between 50 and 69 years old (p < 0.034), OR, 3.6, 95% CI, 1.3-9.9 (p < 0.014). CONCLUSION Triangular fibrocartilage complex abnormalities are common in symptomatic and asymptomatic wrists, and they are increasingly common with age. As in all situations where abnormalities are so common that they may be incidental, we need (1) a reliable and accurate method for determining whether these abnormalities are the cause of symptoms; and (2) evidence that treatment of these abnormalities improves symptoms better than placebo. LEVEL OF EVIDENCE Level III, prognostic study. See the Instructions for Authors for a complete description of levels of evidence.

Abstract
OBJECTIVES The aims of the study were to evaluate the role of magnetic resonance arthrography (MRA) of the wrist in detecting full-thickness tears of the triangular fibrocartilage complex (TFCC) and to compare the results of the magnetic resonance arthrography (MRA) with the gold standard arthroscopic findings. METHODS The study was performed at King Hussein Medical Center, Amman, Jordan, between January 2008 and December 2011. A total of 42 patients (35 males and 7 females) who had ulnar-sided wrist pain and clinical suspicions of TFCC tears were included in the study. All patients underwent wrist magnetic resonance arthrography (MRA) and then a wrist arthroscopy. The results of MRA were compared with the arthroscopic findings. RESULTS After comparison with the arthroscopic findings, the MRA had three false-negative results (sensitivity = 93%) and no false-positive results. A total of 39 patients were able to return to work. Satisfaction was high in 38 of the patients and 33 had satisfactory pain relief. The sensitivity of the wrist MRA in detecting TFCC full-thickness tears was 93% (39), and specificity was 80% (16/20). The overall accuracy of wrist arthroscopy in detecting a full-thickness tear of the TFCC in our study was 85% (29/34). CONCLUSION These results illustrate the role of wrist MRA in assessing the TFCC pathology and suggest its use as the first imaging technique, following a plain X-ray, in evaluating patients with chronic ulnar side wrist pain with suspected TFCC injuries.

Abstract
The purpose of this study was to evaluate the diagnostic test accuracy of X-ray arthrography in the detection of TFCC tear. Both published and unpublished databases were searched from their inception to August 2010. All studies comparing the diagnostic accuracy of X-ray arthrography (index test) to arthroscopy (reference standard) for patients with suspected TFCC tears were included in this review. Twelve studies assessing 430 patients (430 wrists) satisfied the eligibility criteria and were included. X-ray arthrography presented with a pooled sensitivity of 76.2% and specificity of 92.5% for the detection of complete TFCC tear. The triple-compartment injection X-ray arthrography was superior to the single-compartment injection technique. To conclude, the diagnostic test accuracy of X-ray arthrography is limited. Neither the single- nor the triple-compartment injection arthrography method is acceptable, given their reported low sensitivities. Further evaluation of the diagnostic test accuracy of Magnetic Resonance Arthrography and Magnetic Resonance Imaging is therefore warranted.

Abstract
BACKGROUND Triangular fibrocartilaginous complex (TFCC) tears are common sources of ulnar-sided wrist pain and resultant functional disability. Diagnosis is based on the history and clinical examination as well as radiographic evidence of a TFCC central perforation or a radial/ulnar tear. The purpose of this study was therefore to evaluate the diagnostic accuracy of magnetic resonance imaging (MRI) and magnetic resonance arthrography (MRA) in the detection of TFCC injury in the adult population. METHODS Published and unpublished literature databases were searched. Two-by-two tables were constructed to calculate the sensitivity and specificity of MRI or MRA investigations against arthroscopic outcomes. Pooled sensitivity and specificity values and summary receiver operating characteristic curve evaluations were performed. The methodological quality of each study was assessed with use of the QUADAS (Quality Assessment of Diagnostic Accuracy Studies) tool. RESULTS Twenty-one studies were included in the review, and these series included a total of 982 wrists. On meta-analysis, MRA was superior to MRI in the investigation of full-thickness TFCC tears, with a pooled sensitivity of 0.75 and a pooled specificity of 0.81 for MRI compared with 0.84 and 0.95, respectively, for MRA. MRA and MRI performed at greater field strengths were reported to have greater sensitivity and specificity than those performed at lower field strengths. There were insufficient data to assess the diagnostic test accuracy for partial-thickness TFCC tears. CONCLUSIONS Given its acceptable diagnostic test accuracy, it is recommended that MRA, rather than MRI, be performed in when there are questions about the diagnosis and subsequent management of patients with ulnar-sided wrist pain.

Abstract
BACKGROUND The present study evaluated the importance of visualizing both sides of the triangular fibrocartilage complex (TFCC) when diagnosing ulnar wrist pain. METHODS A total of 20 patients with ulnar wrist pain who underwent both radiocarpal joint (RCJ) and distal radioulnar joint (DRUJ) arthroscopy were studied retrospectively. TFCC was graded as normal or as having wear or tear. The definitive diagnosis was made by evaluating the TFCC from both joints. The medical records were reviewed to document the preoperative diagnosis, arthroscopic findings, postoperative diagnosis, and operative procedure(s) performed after the arthroscopic examinations. The patients' status at final follow-up was evaluated using the modified Green and O'Brien wrist scoring system. The TFCC grading on RCJ and DRUJ arthroscopies was compared. RESULTS The final diagnosis was modified after arthroscopic examination in three cases (15%). In six patients (30%), DRUJ arthroscopy revealed pathological TFCC findings that could not be detected on RCJ arthroscopy. The DRUJ arthroscopy detected wear or degenerative changes seen only on the proximal aspect of the TFCC in four patients and tear in two patients. On the other hand, in only one patient (5%) were there no pathological findings observed from the DRUJ portal, although RCJ arthroscopy found wear. In eight patients (45%), the arthroscopic grading of TFCC was the same on RCJ and DRUJ arthroscopy; of these, the TFCC was graded as normal in one patient, showing wear in three patients, and with a tear in five patients. For diagnosing TFCC pathology, RCJ arthroscopy had a sensitivity of 68% and a negative predictive value (NPV) of 14%, whereas the sensitivity was 95% and the NPV was 50% for DRUJ. CONCLUSIONS Adding DRUJ arthroscopy to RCJ arthroscopy enables more accurate diagnosis of TFCC pathology because the proximal aspect of the articular disk and the foveal insertion of the distal radioulnar ligament can be visualized.

Abstract
PURPOSE The purposes of this study were to assess the diagnostic capacity of a new high-resolution imaging protocol for the wrist and triangular fibrocartilage complex (TFCC) lesions at 3.0 T and to compare it with our established 1.5-T protocol. MATERIALS AND METHODS Twenty-one patients with an acute wrist trauma were examined at a 3.0-T imaging system and agreed to undergo an additional examination at 1.5 T. Magnetic resonance imaging was performed with 1.5-T (standard wrist coil) and 3.0-T (purpose-build phased-array coil) imaging system, using coronal T1-weighted turbo-spin-echo, proton density-weighted fat-saturated, and coronal and axial contrast-enhanced T1-weighted gradient-echo fat-saturated sequences, with reduced voxel size from 0.50 x 0.50 x 3.0 mm (1.5 T) to 0.20 x 0.20 x 1.5 mm (3.0 T). For qualitative analysis, 2 observers assessed in consensus delineation, image quality, and artifacts in anatomical landmarks (cartilage, TFCC, and TFCC lesion) and ranked them on a 5-point scale from 1 (nondiagnostic) to 5 (optimal). For quantitative analysis, measurements of the contrast-to-noise ratio were obtained between disk and surrounding tissue. RESULTS All parts of the TFCC and TFCC lesions (n = 14) were seen significantly better at 3.0 T (mean [SD], 4.6 [0.5] vs 2.6 [1.2], P < 0.0001), with higher ranked overall image quality. In 3 cases, TFCC lesions were seen only at 3.0 T. Proton density-weighted fat-saturated sequence had significantly more artifacts at 3.0 T (2.5 [0.6] vs 1.9 [0.5], P < 0.001) in contrast to T1 sequences. Quantitative evaluation showed significantly higher contrast-to-noise ratio for 3.0 T (5.0 [1.1] vs 3.9 [0.9], P < 0.0001). CONCLUSION Depiction of anatomy and pathology of the TFCC benefits significantly from 3.0-T imaging when higher signal-to-noise ratio is invested into improved spatial resolution. Especially small lesions of the disk were detected only or better at 3.0 T.

Abstract
PURPOSE The diagnostic sensitivity, specificity, and accuracy of 1.5 Tesla (T) and of 3.0T magnetic resonance imaging (MRI) are correlated with wrist arthroscopy findings in patients presenting with ulnar-sided wrist pain. METHODS The records and diagnostic MRI scans of 102 patients who presented between 1997 and 2006 with ulnar-sided wrist pain were evaluated. Preoperative MRI scans at 1.5T (n = 70) and 3.0T (n = 32) were evaluated by 2 experienced musculoskeletal radiologists with different levels of experience who were blinded to the arthroscopic findings. Preoperative MRI findings for the triangular fibrocartilage complex (TFCC), scapholunate, ulnotriquetral, and lunotriquetral ligaments were recorded and compared with findings at diagnostic arthroscopy. The sensitivity, specificity, and accuracy were calculated for both the 1.5T and 3.0T preoperative MRI scans. Statistical comparisons were made using chi-square test and JMP 6.0 software. RESULTS 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. CONCLUSIONS 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.

Abstract
PURPOSE To determine whether high-resolution magnetic resonance imaging (MRI) could detect injuries to the triangular fibrocartilage complex (TFCC). METHODS Eleven patients who showed both a positive sign during the ulnocarpal stress test and tenderness at the distal end of the ulna had a high-resolution MRI using a 47-mm diameter microscopy coil. Six regions of the TFCC were investigated for injury: the radial attachment, disc, ulnar attachment of the triangular fibrocartilage (TFC), ulnotriquetral ligament, palmar radioulnar ligament (PRUL), and dorsal radioulnar ligament (DRUL). Arthroscopy was performed subsequently on each patient. RESULTS For injuries to the radial attachment or the disc of the TFC, a high-resolution MRI showed 100% sensitivity and 100% specificity compared with arthroscopy. In 3 cases in which injury to the ulnar attachment of the TFC was detected with MRI and examination showed a positive piano-key sign and distal radioulnar joint instability, only 1 injury was confirmed with arthrotomy. For MRI diagnosis of an ulnotriquetral ulnolunate attachment injury, the sensitivity was 100% and the specificity was 70%; however, 3 cases had false-positive results. Finally MRI had 100% sensitivity for detecting DRUL and PRUL injuries, although specificities were 75% and 83%, respectively. With MRI there were 2 false-positive DRUL injury diagnoses and 1 false-positive PRUL injury diagnosis. CONCLUSIONS High-resolution MRI using a microscopy surface coil allowed assessment of each TFCC component and showed a higher accuracy for diagnosing injuries to the radial attachment and the disc of the TFC compared with previous studies. High-resolution MRI, however, was not able to diagnose DRUL, PRUL, or ulnolunate ligament injuries accurately. TYPE OF STUDY/LEVEL OF EVIDENCE Diagnostic III.

Abstract
Magnetic resonance (MR) imaging for chronic wrist pain is challenging. Correct assessment of the triangular fibrocartilage, hyaline cartilage, ligaments, and tendons has become mandatory for comprehensive decision making in wrist surgery. The MR technique, potential and limits of MR imaging in patients with chronic wrist pain will be discussed. MR arthrography with injection of gadolinium-containing contrast material into the distal radioulnar joint is suggested for evaluation of the triangular fibrocartilage. The clinically meaningful ulnar-sided peripheral tears are otherwise hard to diagnose. The diagnostic performance of MR imaging for interosseous ligament tears varies considerably. The sensitivity for scapholunate ligament tears is consistently better than for lunotriquetral ligament tears. Gadolinium-enhanced MR imaging is considered to be the best technique for detecting established avascularity of bone, but the assessment of the MR results remains challenging. Most cases of ulnar impaction syndrome have characteristic focal signal intensity changes in the ulnar aspect of the lunate. Avascular necrosis of the lunate (Kienböck's disease) is characterized by signal changes starting in the proximal radial aspect of the lunate. MR imaging is extremely sensitive for occult fractures. Questions arise if occult posttraumatic bone lesions seen on MR images only necessarily require the same treatment as fractures evident on plain films or computed tomography (CT) images. MR imaging and ultrasound are equally effective for detecting occult carpal ganglia. Carpe bossu (carpal boss) is a bony protuberance of a carpometacarpal joint II and III which may be associated with pain.

Abstract
A technique of wrist arthrography is presented using an adhesive marker-plate with radiopaque coordinates to identify precisely sites for puncture arthrography of the wrist and to obviate the need for fluoroscopic guidance. Radiocarpal joint arthrography was performed successfully in all 24 cases, 14 in the cadaveric wrists and 10 in the live patients. The arthrographic procedure described in this study is simple, safe, and rapid, and has the advantage of precise localisation of the site for puncture without need for fluoroscopic guidance.

Abstract
OBJECTIVE The aim of our study was to compare the findings of high-resolution sonography of the triangular fibrocartilage with those of MRI and arthroscopy. SUBJECTS AND METHODS. Thirteen patients with clinically suspected triangular fibrocartilage tears prospectively underwent sonography, followed by MRI, of their wrists. Triangular fibrocartilage tears were classified as predominantly ulnar or predominantly radial. Only the surgeon was aware of the results of both studies, and eight patients subsequently underwent arthroscopy. The findings of the different techniques were compared. RESULTS For the presence or absence of a tear, seven (87.5%) of eight sonographic examinations correlated with arthroscopy, and 11 (84.6%) of 13 sonographic examinations correlated with MRI. Sonography missed one small radial tear that was detected at arthroscopy and MRI, but sonography showed an ulnar tear in triangular fibrocartilage that appeared normal on MRI. CONCLUSION High-resolution sonography shows good correlation with MRI and arthroscopy for the evaluation of triangular fibrocartilage tears. Sonography has the potential to be a rapid and cost-effective means of diagnosing tears of the triangular fibrocartilage, particularly those involving the ulnar aspect of the cartilage.

Abstract
OBJECTIVE To compare MR images of the triangular fibrocartilage complex (TFCC) using microscopy coils with those using a conventional surface coil qualitatively and quantitatively. DESIGN AND PATIENTS Proton density-weighted images and T2*-weighted images of the TFCC from ten normal volunteers were obtained with a conventional surface coil (C4 coil; 80 mm in diameter), a 47-mm microscopy surface coil and a 23-mm microscopy surface coil) at 1.5 T. Qualitative image analysis of MR images with three coils was performed by two radiologists who assigned one of five numerical scores (0, nonvisualization; 1, poor; 2, average; 3, good; 4, excellent) for five TFCC components, which were disc proper, triangular ligament, meniscus homologue, ulnotriquetral and ulnolunate ligament. Quantitative analysis included the signal-to-noise ratio (S/N) of the disc proper of TFCC, the lunate cartilage, the lunate bone and the contrast-noise-ratio (C/N) between articular cartilage and disc proper or bone marrow were measured. RESULTS All structures show higher scores qualitatively on MR with microscopy coils than those with a C4 coil, and the difference was significant with the exception of the ulnolunate ligament. MR with microscopy coils showed significantly higher S/N values than those with a conventional surface coil (P<0.05 to P<0.001). T2*-weighted images using microscopy coils showed significantly higher cartilage-disc proper C/N and cartilage-bone marrow C/N (P<0.01 to P<0.001). On proton density-weighted images, the C/N between cartilage and disc proper with two microscopy coils was significantly higher (P<0.01) than that with a conventional coil. CONCLUSION High-resolution MR images of the normal wrist using microscopy coils were superior to those using a conventional surface coil qualitatively and quantitatively. High-resolution MR imaging with a microscopy coil would be a promising method to diagnose TFCC lesions.

Abstract
The treatment of triangular fibrocartilage tears in the athlete presents more of a rehabilitation challenge than a surgical technique challenge. The rehabilitation regimen is a function of the sport. Although injuries to the shoulder and knee can be career ending, injuries to the TFCC usually, but not always, can be treated successfully.

Abstract
AIM To review the published diagnostic performance statistics for magnetic resonance imaging (MRI) of the wrist for tears of the triangular fibrocartilage complex, the intrinsic carpal ligaments, and for osteonecrosis of the carpal bones. MATERIALS AND METHODS We used Medline and Embase to search the English language literature. Studies evaluating the diagnostic performance of MRI of the wrist in living patients with surgical confirmation of MR findings were identified. RESULTS We identified 11 studies reporting the diagnostic performance of MRI for tears of the triangular fibrocartilage complex for a total of 410 patients, six studies for the scapho-lunate ligament (159 patients), six studies for the luno-triquetral ligament (142 patients) and four studies (56 patients) for osteonecrosis of the carpal bones. CONCLUSIONS Magnetic resonance imaging is an accurate means of diagnosing tears of the triangular fibrocartilage and carpal osteonecrosis. Although MRI is highly specific for tears of the intrinsic carpal ligaments, its sensitivity is low. The diagnostic performance of MRI in the wrist is improved by using high-resolution T2* weighted 3D gradient echo sequences. Using current imaging techniques without intra-articular contrast medium, magnetic resonance imaging cannot reliably exclude tears of the intrinsic carpal ligaments. Hobby, J. L. (2001).

Abstract
PURPOSE To characterize triangular fibrocartilage (TFC) defects in symptomatic and contralateral asymptomatic wrists. MATERIALS AND METHODS Communicating and noncommunicating defects of the TFC were depicted on bilateral wrist arthrograms in 56 patients with unilateral wrist pain and without associated lesions of the scapholunate or lunotriquetral ligaments. The exact location of each TFC lesion was noted. RESULTS Communicating defects were noted in 36 (64%) of 56 symptomatic and in 26 (46%) of 56 asymptomatic wrists. Twenty-five (69%) of 36 communicating defects were bilateral. Except for one defect in each group of symptomatic and asymptomatic wrists, all communicating defects were noted radially. Noncommunicating defects were noted in 28 (50%) of 56 symptomatic wrists and in 15 (27%) of 56 asymptomatic wrists. Eleven (39%) of 28 noncommunicating defects were bilateral. On the symptomatic side, 28 of 36 noncommunicating defects (including eight multiple defects) were located proximally at the ulnar side. On the asymptomatic side, 11 of 17 noncommunicating defects (including two multiple defects) were at or near the ulna. CONCLUSION Noncommunicating TFC defects, which typically are located on the proximal side of the TFC near its ulnar attachment, have a more reliable association with symptomatic wrists than do communicating defects. Radial-sided communicating defects described in the literature (Palmer type 1A and 1D) as posttraumatic commonly are seen bilaterally and in asymptomatic wrists.

Abstract
The aim of this prospective study was to determine whether peripheral tears of the triangular fibrocartilage complex (TFCC) in patients younger than the osteoporotic age (males,<60 years; females, <50 years) were related to chronic distal radioulnar joint (DRUJ) instability. Fifty-one patients (27 women) with displaced distal radial fractures were included in the study. The median age was 41 years (range, 20-57 years). Arthroscopy at the time of fracture showed complete or partial TFCC tears in 43 patients (24 had only peripheral tears, 10 had only central perforations, and 9 had combined tears). The 1-year (range, 11-27 months) follow-up period included an interview, physical examination, and radiographic evaluation. Ten of the 11 patients with complete peripheral TFCC tears had DRUJ instability at the follow-up examination compared with 7 of the 32 patients with only partial or no peripheral tears. Patients with instability of the DRUJ had a worse Gartland and Werley wrist score. Instability was not associated with any radiographic finding either at the time of fracture or at the follow-up examination. Initial fracture or nonunion of the styloid was even slightly more common in stable patients.
