Evaluation of Staple Watson Wrist Arthrodesis

Study Overview
=================
Brief Summary
-----------------
When the wrist is damaged, for traumatic or degenerative reasons, the cartilage is worn out and the bones rub together: this is osteoarthritis. In order to stop this pain, it may be necessary to block these bones from each other, sacrificing mobility to achieve indolence. Multiple techniques are described according to the type of osteoarthritis and for each type of osteoarthritis itself, but the principle remains the same. The methods currently commonly proposed are the staple and the screwed plate. The aim of the study is to evaluate the surgical practice of the Orthopaedics and Traumatology department of the University Hospital of Rennes, and its long-term results, as this type of surgery is intended to be definitive.

Detailed Description
-----------------
The surgery performed in the Orthopaedics and Traumatology department of the University Hospital of Rennes, has 2 notable points: its technique and its equipment. The procedure is based on the staples 4Fusion1 (Stryker/Memometal), which is still poorly assessed in the literature. The surgical procedure has several technical specificities: intra osseous cartilage freshening and preservation of the lunotriquetral ligament if intact.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Assessment of the surgical procedure | Assessement of the bones consolidation at at least 6 weeks post-surgery, using a radiological criterion : 3 out of 4 line spacing merged | Day 1 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Pain assessment | Evolution in pain reported by the patient by a pain assessment scale, with reference to preoperative assessment. Evaluation is based on the visual analog scale (VAS) in which the patients select a whole number (0-10 integers) that best reflects the intensity of their pain | Day 1 | 
| Grip force | Change of the grip force measured by Jamar's hydraulic dynamometer, compared to pre-operative assessment | Day 1 | 
| Functional assessment of the wrist with Mayo Wrist Score | International validated functional score. This evaluation yields a total score out of 100 points qualified as poor if <65 up to Excellent if >90. | Day 1 | 
| Functional assessment of the wrist with Quick Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire | International validated functional score. The Quick DASH tool uses a 5-point Likert scale from which the patient can select an appropriate number corresponding to his/her severity level/ function level | Day 1 | 
| Functional assessment of the wrist with Patient-Rated Wrist Evaluation | International validated functional score. The Patient-Rated Wrist Evaluation (PRWE) allows patients to rate their levels of wrist pain and disability from 0 to 10 | Day 1 | 
| Patient's overall satisfaction about surgery | Patient's overall satisfaction assessed by the question: Would you do the surgery again? (balance between 0 and 10) | Day 1 | 
| Material hindrance | Specific items assessed during clinical evaluations. Quoted as 1 if at least one of the following events is evoked : Material-related pain, skin irritation, re-intervention for remote ablation | Day 1 | 
| Mean mobility arc | Measurement of the arc of mobility in flexion - extension by goniometer | Day 1 |
