Low-profile plate fixation in arthrodesis of the first metacarpophalangeal joint.

Fifty-one consecutive arthrodeses (46 patients) of the first metacarpophalangeal joint were retrospectively reviewed, after fixation with a Leibinger low-profile titanium plate, using a cup-and-cone technique. Primary bone union was achieved in 98%. Three cases required removal of the plate and one case a tenolysis. Follow-up time was 13-92 months (mean 52). There was no correlation between patient satisfaction and position of fusion. We conclude that this technique gives a high rate of union, a short period of immobilization and rehabilitation, and a reliable position at the site of fusion.
