Rupture of digital extensor tendons following distal ulnar resection
WL Newmeyer and DP Green
We have treated four patients with rupture of one or more digital extensor
tendons following a distal ulnar resection for a traumatic problem. The
rupture was caused by the abrasive effect of the distal part of the ulna at
the site of resection during pronation and supination. Two patients were
treated with a silicone-rubber prosthesis ad tendon grafts and two, with
resection of an ulnar bone spike and local tendon transfers. Tendon rupture
is best avoided by strict adherence to the surgical technique described by
Darrach. If rupture of the tendon occurs, reconstructive procedures must be
devised to repair the individual lesion found at operation.
