Lasso stabilization of the distal ulna after tumor resection: a report of two cases.

Two patients with complicated giant cell tumors of the distal ulna were treated by resection of 7.5 and 5.5 cm of the ulna, respectively. The proximal ulnar stump was stabilized with a lasso tendon graft, which allowed the patients to return to presurgery activities. The technique described is a modification of a tendon loop reconstruction used by Bunnell.
