Abstract
Purpose
To report the clinical outcomes of a volar plate reinforcing technique with free tendon grafts after sesamoid excision for the surgical treatment of subsesamoid arthritis of the metacarpophalangeal (MCP) joint of the thumb.
Materials and Methods
Eleven consecutive patients that underwent sesamoid excision and volar plate reinforcement using a palmaris longus free tendon graft were enrolled. There were 7 males and 4 females, with an average age of 46 (range, 30-56 years). Post-traumatic arthritis after a hyperextension injury of the thumb was present in 9 patients. Two patients had idiopathic arthritis. All patients were evaluated by objective and subjective criteria, the mean follow-up duration was 19 months (range, 12-35 months).
Results
The results were satisfactory overall (3 excellent, 7 good, 1 poor). The mean grip strength and pinch strength significantly improved from 63.0% and 51.3%, respectively, preoperatively, to 84.9% and 88.9%, postoperatively. The mean range of motion for the MCP joint was -5.9/50.9 degrees. The mean DASH and MHQ scores showed significant improvement compared to the preoperative scores.
