Presentation
Pain and numbness in thumb, past history of multiple episodes of trauma to thumb while playing cricket.
Patient Data
High-grade partial tear of ulnar collateral ligament of 1st metacarpophalangeal joint at proximal phalanx with cortical irregularity at proximal phalanx insertion. Adductor aponeurosis, however, appears to lie proximal to it.
Mild thickening and irregularity of radial collateral ligament are seen – likely sequelae of old sprain / partial tear.
Fat suppression was not complete in the first sequence which was repeated. However, the ligamentous structures are well visualized.
Case Discussion
Findings consistent with high grade partial tear of ulnar collateral ligament of 1st metacarpophalangeal joint at proximal phalanx.
