Objectives: To evaluate the results of ligament reconstruction tendon interposition arthroplasty in osteoarthritis of the carpometacarpal joint of the thumb.
Methods: Ten thumbs of eight patients who underwent arthroplasty for osteoarthritis at the base of the thumb evaluated grip, key pinch strengths, ROM and radiologically which did not respond satisfactorily to conservative treatment modalities.
Results: All patients had improved pain, increase in grip %45, key pinch strengths %56, mean ROM were 30 degrees. Radiographically, any of the thumb was detected migration, subluxation.
Conclusion: In our applied technique, successfull results were achieved in the treatment with use the fcr tendon in CMC osteoarthritis.
