ABSTRACT
Total trapeziometacarpal (TMC) joint replacement is increasingly being performed for the treatment of basal joint arthritis. However, complications such as instability or loosening are also frequent with TMC ball-and-socket joint replacement. Management of these complications lacks consensus. The purpose of this study was to report the results of 12 cases of failed TMC joint replacement that were treated by trapeziectomy with ligament reconstruction and tendon interposition (LRTI) arthroplasty. The follow-up consisted of functional (numerical scale, DASH score, satisfaction), physical (range of motion, strength) and radiological (Barron and Eaton ratio measurement) assessments. At a mean follow-up of 21 months, 11 patients were satisfied or very satisfied after surgery. The mean pain score was 2/10 and the mean DASH score 30/100. Mean thumb palmar and radial abduction was 40°. Thumb opposition measured by the Kapandji technique was 9/10. The height ratio was slightly increased. Trapeziectomy with LRTI after TMC joint replacement appears to be an attractive salvage procedure.

The TASER(®) is a self-defense weapon whose use has now become commonplace among law enforcement agencies. Electronic control weapons were first used in the USA in the 1990s and then adopted in Europe and France. We report a case of an 18-year-old male who presented a penetrating lesion of the middle phalanx of the left index finger. To the best of our knowledge, this is the first complex finger injury due to the TASER(®). It highlights the potential major risks to finger vitality and function with use of this electrical weapon.
