Comparison Between Anterior Approach (Deltopectoral) and Lateral Approach (Deltoid Splitting) in Shoulder Reverse Arthroplasty for Proximal Humerus Fracture

• Quick dash score[ Time Frame: 3, 6 and 12 months ]
  the Quick Dash score is a functional assessment of the shoulder. The score varies between 0 and 100, more the value is better brought up is the score
• SF12 score[ Time Frame: 3, 6 and 12 months ]
  The SF12 score is a quality of life assessment. The score varies between 0 and 100, more the value is better brought up is the score
• Alder score[ Time Frame: 3, 6 and 12 months ]
  Assessment of external rotation of the shoulder. The score varies between 0 and 100, more the value is better brought up is the score
• The Simple Shoulder Test (SST)[ Time Frame: 3, 6 and 12 months ]
  The Simple Shoulder Test is functional assessment of the shoulder. The score varies between 0 and 100, more the value is better brought up is the score
• WOOS (The Western Ontario Osteosarthritis )[ Time Frame: 3, 6 and 12 months ]
  The Western Ontario Osteosarthritis of the shoulder index is a quality of life measurement tool for osteoarthritis of the shoulder. The score varies between 0 and 100, more the value is better brought up is the score
• intensity of pain[ Time Frame: pre op, 3, 6 and 12 months ]
  THE VISUAL SIMILAR SCALE is auto-completed. For the intensity of pain, the scale varies between " no pain " (the score of 0) and " the pain so badly as he could be " or " the worst conceivable pain " (the score of 10)
• Radiologic evaluation[ Time Frame: pre op, 3, 6 and 12 months ]
  Radiologic evaluation
• Complications[ Time Frame: pre op, 3, 6 and 12 months ]
  list of the complications

The aim of the study consists in comparing two surgical approaches (deltopectoral versus lateral deltoid splitting) in the treatment of proximal humerus fractures treated with a reversed total shoulder arthroplasty The assessment will focus on clinical (clinical scores, efficacy, safety…) and radiological results, between these two types of surgical approaches by using a prospective, randomized analysis.

• Procedure: Reversed total shoulder arthroplasty
  Replacement of the proximal humeral head by a reversed prosthesis through an anterior approach
• Procedure: lateral approach
  Replacement of the proximal humeral head by a reversed prosthesis through a lateral approach

• Active Comparator: deltopectoral approach
  the patients are treated with deltopectoral approach surgery
• Other: lateral approach
  the patients are treated with a lateral approach surgery
