Results of the Tactys Implant in Proximal Interphalangeal Joint Arthroplasty

Study Overview
=================
Brief Summary
-----------------
Study at middle term of the functional and radiographic results of proximal interphalangeal joint arthroplasty with the Tactys prothesis. The aim is to evaluate if the short term results are maintained in time.

Detailed Description
-----------------
The inclusion criteria is any patient who has undergone a proximal interphalangeal joint arthroplasty with the Tactys prothesis between january 2015 to january 2020 in the Centre Chirurgical Emile Gallé in Nancy. The functional results evaluated are range of motion, force, pain, functional score as Quick DASH and the radiological one are clinodactyly, periprosthetic ossifications and loosening, dislocation and implant subsidence. Data is registered from the medical folder of every patient.
