The Role of Wrist Magnetic Resonance Arthrography in Diagnosing Triangular Fibrocartilage Complex Tears Experience at King Hussein Medical Center, Jordan
Journal Title: Sultan Qaboos University Medical Journal - Year 2013, Vol 13, Issue 2
Abstract
Objectives: Te 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 fbrocartilage complex (TFCC) and to compare the results of the magnetic resonance arthrography (MRA) with the gold standard arthroscopic fndings. Methods:Te 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. Te results of MRA were compared with the arthroscopic fndings. Results: After comparison with the arthroscopic fndings, 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. Te sensitivity of the wrist MRA in detecting TFCC full-thickness tears was 93% (39), and specifcity was 80% (16/20). Te overall accuracy of wrist arthroscopy in detecting a full-thickness tear of the TFCC in our study was 85% (29/34). Conclusion: Tese results illustrate the role of wrist MRA in assessing the TFCC pathology and suggest its use as the frst imaging technique, following a plain X-ray, in evaluating patients with chronic ulnar side wrist pain with suspected TFCC injuries.
