- Abstract:
- The trapeziometacarpal (TMC) joint is an important joint for manual function. Osteoarthritis (OA) of this joint leads to loss of strength and motion, which affects patients in their activities of daily living. TMC OA is a common disease in the elderly, mostly postmenopausal women. Literature describes a large number of different conservative and operative treatment options. The analysis conducted in this thesis compares the Moovis® prosthesis and the resection arthroplasty (RA) with tendon interposition in the technique of Epping. The randomized, controlled and double-blind study includes 23 patients, accounting for 24 thumb surgeries - forming two study groups based upon the surgery method used. Data were collected with the help of a questionnaire and a standardized examination. Subsequently, data have been classified and the aspects: range of motion, pain, patient satisfaction, quality of life and hand function have been evaluated. The 6-weeks postoperative VAS of both groups was compared, using the Mann-Whitney-U-Test. Differences within one group were evaluated using the Wilcoxon-Rank-Sum-Test. Comparison with the norm sample were conducted using t-Test. The statistical analysis was performed with SPSS 23. In this study, cases of 24 thumbs in 23 patients (95.9 % female) with a median age of 56.5 (48-77) were included. Median VAS 6 weeks postoperative was 1 (0-6) in patients treated with the prosthesis and 2 (0-5) in patients treated with RA. The difference between the two groups was not significant (p=0.093) concerning the VAS six weeks postoperative No statistically significant differences could be evaluated for range of motion, pain, patient satisfaction and hand function. With regard to quality of life, statistically significant differences concerning the PCS six weeks as well as three months after surgery between both groups could be observed. Both methods displayed a good short-term outcome. The DASH-Score improved in both groups. The VAS did not show a significant difference regarding both methods. Our data are in line with the findings of Regnard implicating that the Moovis® prosthesis provides good short-term outcome. The physical quality of life, both six weeks and 3 months after surgery, seem to differ between both groups.
