Perioperative Complications in Reversed Shoulder Arthroplasties

Study Overview
=================
Brief Summary
-----------------
Retrospective observational study of reversed shoulder arthroplasties by proximal humeral fracture. Analysis of preoperative risk factors as well as minor and major complications at the first week, 90 days and 1 year.

Detailed Description
-----------------
The study is a multicenter retrospective observational study (3 centers). Data are collected from 105 patients over 65 years-old undergoing reversed shoulder arthroplasties by proximal humerus fractures, in 3 or 4 parts. Patient information is obtained from the clinical records in their usual preoperative assessment, and follow-up on the usual routine checks, at the first week, 90 days and 1 year. Minor and major complications rates are evaluated according to preoperative risk (ASA), underlying diseases and according to anticoagulant / antiaggregant treatments. Likewise, transfusion rates related to ASA, as well as length of hospital stay related to it.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of patients affected by minor complications according to preoperative risk (ASA) in reversed shoulder arthroplasties due to complex proximal humeral fractures. | Minor complications are medical complications, which usually don't affect to the functional outcome of arthroplasties | First week after surgery | 
| Number of patients affected by minor complications according to preoperative risk (ASA) in reversed shoulder arthroplasties due to complex proximal humeral fractures. | Minor complications are medical complications, which usually don't affect to the functional outcome of arthroplasties | 90 days after surgery | 
| Number of patients affected by minor complications according to preoperative risk (ASA) in reversed shoulder arthroplasties due to complex proximal humeral fractures. | Minor complications are medical complications, which usually don't affect to the functional outcome of arthroplasties | 1 year after surgery | 
| Number of patients affected by major complications according to preoperative risk (ASA) in reversed shoulder arthroplasties due to complex proximal humeral fractures. | Major complications are surgical complications( dislocation, periprosthetic fracture, infection) which usually affect to the functional outcome and can lead to a revision surgery | First week after surgery | 
| Number of patients affected by major complications according to preoperative risk (ASA) in reversed shoulder arthroplasties due to complex proximal humeral fractures. | Major complications are surgical complications( dislocation, periprosthetic fracture, infection) which usually affect to the functional outcome and can lead to a revision surgery | 90 days after surgery | 
| Number of patients affected by major complications according to preoperative risk (ASA) in reversed shoulder arthroplasties due to complex proximal humeral fractures. | Major complications are surgical complications( dislocation, periprosthetic fracture, infection) which usually affect to the functional outcome and can lead to a revision surgery | 1 year after surgery | 

Secondary Outcome Measures

| Number of patients with cardiovascular diseases affected by major complications after surgery | Underlying diseases group: cardiovascular, neurological, rheumatic, psychiatric, neoplasic. | 1 year after surgery | 
| Number of patients undergoing anticoagulant treatment with minor complications | Previous acenocoumarol treatment | First week after surgery | 
| Number of patients undergoing anticoagulant treatment with major complications | Previous acenocoumarol treatment | First week after surgery |

| Number of patients undergoing antiplatelet treatment with major complications | Previous Acetylsalicylic acid (Aspirin), triflusal, ticlopidine, clopidogrel or prasugrel | First week after surgery | 
| Number of patients undergoing antiplatelet treatment with minor complications | Previous Acetylsalicylic acid (Aspirin), triflusal, ticlopidine, clopidogrel or prasugrel | 90 days after surgery | 
| Number of patients undergoing antiplatelet treatment with major complications | Previous Acetylsalicylic acid (Aspirin), triflusal, ticlopidine, clopidogrel or prasugrel | 90 days after surgery |
