Patient Satisfaction After Silicone Metacarpophalangeal Arthroplasty

Study Overview
=================
Brief Summary
-----------------
The primary objective of this study is to identify determinants of long-term patient satisfaction after hand reconstruction using silicone metacarpophalangeal arthroplasty (SMPA). The investigators hypothesize that appearance of the hand, ulnar drift, range of motion, pain, hand function and intake of the newer antirheumatic drugs (i.e. biologicals) influence patient satisfaction.

Detailed Description
-----------------
This is an ambidirectional, monocenter research project consisting of a retrospective chart review and a prospective cohort project. Participants fulfilling all of the following inclusion criteria are eligible for the project: Patients with rheumatoid Arthritis (RA) / Psoriasisarthritis / Lupus erythomatodes who had a SMPA between Jan 2007 and one year before the project examination Informed Consent as documented by signature The presence of any one of the following exclusion criteria will lead to exclusion of the participant: Major surgery at another joint at the hand (e.g. proximal interphalangeal (PIP) joint arthroplasty, thumb trapeziectomy) less than 6 months ago Legal incompetence German language barrier to complete the questionnaires

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Satisfaction with the treatment result assessed on a 5-point Likert Scale | The primary outcome is the satisfaction with the treatment result at least one year after surgery and its determinants. It will be quantified using this question: How satisfied are you with the overall result of the SMPA surgery? The response options are: Very satisfied (score 1), somewhat satisfied (score 2), neither satisfied nor unsatisfied (score 3), somewhat unsatisfied (score 4), very unsatisfied (score 5). For further analyses, this question can be dichotomized into the categories of satisfied patients (very satisfied / satisfied) and unsatisfied patients (neither satisfied nor dissatisfied or worse). | at least one year after surgery |
