Info
- laxity and osseous irregularity of the first metacarpophalangeal joint
- complete tear of the first MCPJ ulnar collateral ligament with retraction of the proximal fibres
- the adductor pollicis aponeurosis inserts deep to the proximal aspect of the UCL in keeping with a Stener lesion (see arrowed image)
Case Discussion
The patient went on to have an ulnar collateral ligament repair with an intra-osseous anchor being placed. The interposition of the adductor pollicis aponeurosis between the UCL and the MCPJ prevents healing.
