First carpometacarpal joint osteoarthritis : trapeziectomy with ligament reconstruction and tendon interposition versus ball-and-socket arthroplasty

Abstract

The objective of this study was to compare trape- ziectomy with ligament reconstruction and tendon interposition versus ball-and-socket arthroplasty for first carpometacarpal joint osteoarthritis treatment. In this retrospective study, a total of 98 patients were included between January 2011 and December 2015 : 27 patients were submitted to ligament reconstruction and tendon interposition technique (group A) (mean age of 62.01 years-old) and 71 patients to prosthesis replacement (group B) (mean age of 62,14 years- old). Clinical assessment was undertaken at the last appointment before discharge.

Groups didn’t significantly differ regarding VAS (group A : 1.04 ; group B : 1.03 ; p=0.486) and Quick DASH (group A : 13.72 ; group B : 11.76 ; p=0.290). First carpometacarpal joint osteoarthritis arthro- plasty was associated with greater strength when performing key-pinch (group A : 4.44KgF ; group B : 5.20KgF ; p=0.031) and grip (group A : 19.25KgF ; group B : 22.35 ; p<0.001).

There were no significant differences between groups concerning complications (p=0.502, Fisher’s exact test).

There were no differences in terms of clinical out- come and complication rate between the two groups for patients with first carpometacarpal joint osteo- arthritis stage Eaton II and III. However, patients with prosthesis have greater key-pinch and grip- strength.
