Diagnostic Accuracy of Magnetic Resonance Arthrography and its Correlation with Arthroscopy in the Detection of Lesions Triangular Fibrocartilaginous Complex and Intrinsic Ligaments in the Wrist

Objectives: To assess the diagnostic validity and reliability of magnetic resonance arthrography in identifying lesion triangular intrinsic wrist ligaments fibrocartilaginous complex based on arthroscopy as reference standard preferred modality imaging. Methodology: This was a retrospective validation study that carried out at Radiology department PESSI (Punjab Employees Social Security) Hospital, Islamabad, between April 2019 September 2022. A total 11 patients with an age range 21-58 years, lesions (TFCC), MR were included. images evaluated to integrity ligaments, including those TFCC, scapholunate, lunotriquetral ligament. injection performed into joint, likely help visualize other structures within joint. The under fluoroscopic guidance, size needle used for 20-24G. data collected from arthrograms analyzed using SPSS v 23. Results: patient’s mean 40.0±12.31 years. Out patients, there 6 (55.5%) males 5 (45.5%) females. Sensitivity is 71.4% specificity 75% detecting TFCC defects, 100% sensitivity 85.7% diagnosing ligament defects. had overall accuracy 73% while defects 90.9%. Conclusion: adequate tool when compared arthroscopy.
