Abstract
Introduction
Although there are different surgical options used to treat symptomatic trapeziometacarpal
(TMC) joint arthritis, they all have potential complications which can be difficult
to manage.
Materials and Methods
This retrospective audit describes a modified arthroscopic partial resection arthroplasty
(ARA) of the distal 3-4 mm of the trapezium combined with a postoperative early motion
therapy program to treat TMC joint arthritis.
Results
Patients (N = 46 (50 thumbs)) who had ARA of distal trapezium for TMC joint arthritis were included
in this study. Functional measurements were recorded preoperatively and postoperatively,
with an average follow-up time of 11.7 months. Statistical significance was found
in all measures except radial abduction, interphalangeal joint extension and DASH.
There was an increase of 19.8% in gross grip strength, 19.1% in lateral pinch and
21.8% in force plate measures.
Discussion
In conclusion, ARA of the distal 3-4 mm of the trapezium combined with an immediate
postoperative motion therapy program resulted in the improvement of all outcome measures.
Study and Level of Evidence
Study, Level III.
