Osteoarthritis of basal joint of the thumb represents one of the commonest degenerative diseases of the hand and wrist region. Depending on the severity of clinical symptoms surgical treatment is often recommended. Resection arthroplasty of the CMC joint with tendon interposition can be regarded as the gold standard. The aim of our study is to compare the Burton Pellegrini technique with a new modified technique of resection arthroplasty with interposition of local capsule tissue. We retrospectively evaluated 2 groups of patients. Two Consultant Surgeons took part in the study, one for each group, with each consultant performing trapeziectomies using only one of the techiniques for all his patients. The first group underwent trapeziectomy and local capsule interposition. It consists of 26 patients with a female/male ratio of 20/6, an average age of 64 years (range 53–88), an average follow up of 3.15 years (range 9–1) and a left/right ratio of 16/10. The second group underwent a standard Burton Pellegrini including flexor tendon interposition. It consists of 13 patients with a female/male ratio of 5/8, an average age of 68 years (range 58–85), an average follow up of 4.46 years (range 9–1) and a left/right ratio of 5/8. The outcomes were compared using the Michigan Hand Outcomes Questionnaire. A 2-tailed independent samples t-test was used for the statistical analysis of our data.Background
