Attritional rupture of flexor tendons by the head of the ulna associated with a chronic longitudinal radioulnar dissociation

[Rupture by attrition of the median nerve found during a carpal tunnel release procedure]

We report the finding of a subtotal rupture of the median nerve caused by a "bridge" or"easel" erosion due to a sequela of childhood wrist fracture. This unpublished observation was made during a carpal tunnel release procedure on an 80-year-old patient who was operated on for recurrence of a severe carpal tunnel syndrome 30 years after a previous neurolysis. If the flexor tendon ruptures are widely described, as well as nerve sections following high energy trauma, the median nerve rupture caused by its erosion over a bony projection has never been published at the best of our knowledge.

Rupture of flexor tendons as a complication of a distal radius fracture

Two cases are reported of flexor tendon rupture of ulnar side fingers as a complication after distal radius fracture. One was associated with a prominent distal volar lip of fracture site, the other with a relatively volarly displaced ulnar head due to the dorsally tilted distal radius due to malunion. These may be unique cases of flexor tendon rupture with conservatively treated patients.

Attritional rupture of the flexor tendons to the small finger caused by osteophyte of the ulnar head: case report

We present a rare case of attritional rupture of the flexor tendons to the small finger caused by an osteophyte of the volar aspect of the ulnar head.
