PRCT: Comparing Two Procedures for Ulno-Carpal Abutment Syndrome.

NCT00564980 · Status: TERMINATED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 3

Summary

The purpose of this study is to evaluate two different currently accepted surgical treatments for UAS (ulnocarpal abutment syndrome).

The hypothesis is that ulnar shortening osteotomy procedure will be associated with longer surgical time and increased complication rate when compared to the wafer procedure. It is unclear as to whether there will be a difference in functional outcome between the two groups.

Interventions

PROCEDURE

Wafer Procedure

A dorsal approach to the distal ulna is used dividing the extensor retinaculum between the 5th and 6th compartments. The ulnar head is exposed through a transverse capsulotomy. Cartilage and bone are resected to result in slight negative ulnar variance based on the preoperative pronated grip view. The ulnar styloid and TFCC attachments are preserved. The dorsal capsule and retinaculum are repaired in separate layers.

PROCEDURE

Ulnar shortening osteotomy

A longitudinal incision of approximately 8 cm is made at the distal third of the ulna along the ulnar border of the forearm. The interval between the flexor carpi ulnaris is used. The ulna is exposed at its distal third preserving the periosteum. Care is taken to protect the sensory branches of the lunar nerve. An oblique osteotomy is performed using a reciprocating saw, removing enough bone to result is slight negative ulnar variance. Fixation and compression at the osteotomy site is achieved using a 5 or 6 hole titanium LC-DCP plate.
