We provide information to help patients and caregivers to understand of anatomy, associated symptoms, and arthroplasty of shoulder.
The Shoulder Joint is composed of three bones; humerus, scapula and clavicle. The head of humerus fits into glenoid covered by rotator cuff. The rotator cuff is a combination of tendons and muscles moving your arm. There are two joints in shoulder. One is glenohumeral joint which is between the glenoid of scapula and head of humerus. Other is acromioclavicular joint also called as AC joint.
Shoulder Arthroplasty is intended for patients with painful, disabling joint disease of the shoulder resulting from non-inflammatory degenerative joint disease or rheumatoid arthritis.
In shoulder arthroplasty, damaged parts of bone are removed and replaced by implants. This may involve head of humerus and/or glenoid surface. Osteoarthritis and Rheumatoid arthritis are main indications of shoulder arthroplasty. Post-traumatic condition with injury to shoulder such as fracture of bones may occur which may be treated with shoulder arthroplasty as well. Patient must consult orthopedic specialist for specific condition diagnosis and treatment.
Some of the contraindications are infection, Osteomyelitis, Osteoporosis, Metabolic disorders which may impair bone formation, osteomalacia, vascular insufficiency, muscular atrophy, neuromuscular disease, incomplete or deficient soft tissue surrounding the shoulder.
