Partial forearm posterior interosseous nerve laceration with primary
3: Local crush injury of proximal median nerve with central disruption,
epineurium intact; excellent recovery after primary debridement and
epineural repair. Exploration of digital (4) and median (5) neuromas
late after partial injuries.
When partial nerve function remains, resection and grafting is an
unpredictable solution, and primary repair is preferable for partial
