Case in brief

A young labourer developed acute posterior interosseous nerve (PIN) palsy after undergoing single-incision cortical button fixation for a distal biceps rupture. Postoperative imaging indicated malposition of the Endobutton, leading to urgent re-exploration. The biceps tendon was found to be improperly routed over the PIN, causing nerve compression. After re-routing the tendon and securing it correctly, the patient achieved full neurological recovery within three months.

Diagnostic / clinical pearl

This case underscores the necessity of precise anatomical identification and technique during distal biceps tendon repair to prevent iatrogenic nerve injuries.
