Shoulder Disease
Conditions
Brief summary
The gold standard after shoulder resection for tumors is reconstruction by reverse prosthesis and allograft. This is an intervention also performed for more frequent etiologies (revisions of prosthesis, non cancerous humeral bone loss ...). The results in these etiologies are good, and do not find any particular mechanical complications (including no osteolysis of the graft). In the case of reconstruction for cancer, the numbers of patients are lower (rare pathologies) and some studies on small numbers found osteolysis of the allograft. The aim of this study is to analyze the presence or not osteolysis in these patients, and to quantify it precisely by scanner measurement (no data yet in the literature).
Detailed description
quantify bone stock of the allograft by scanner measurement in post operative and in 6 month to 1 years after surgery. This is a retrospective study, and the scanner was performed routinely every 3 to 6 month, during 2 years, for oncological follow up.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Osteolysis (bone stock in cm3) | within 3 months post operatively and up to 1 year post operatively | allograft bone stock by scanographic measurements after the surgery, and at minimum 6 month follow up |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Constant score | up to 1year post operatively | Shoulder functional evaluation score between 6 points (worst score) and 100 points (better score) |
| Complications | up to 1year post operatively | (infection, dislocation) |
| Revision | up to 1year post operatively | with removal of implant, with or without re implantation |
