X-ray of a total shoulder replacement

Shoulder replacement
Khemarin Seng MD

Shoulder arthroplasty or replacement is a procedure indicated for painful arthritis of the gleno-humeral joint.  Metal and plastic are used to replace the painful, grinding bone of the gleno-humeral joint.  The cause of shoulder arthritis is multifactorial.  Traumatic injury, instability, rotator cuff deficiency and genetics are a few causes.

Recent advances in shoulder replacement have improved patient outcomes.  Modularity and shape of the prosthesis, improved fixation techniques to bone and newer bone preserving procedures have expanded our armamentarium to treat this disabling condition.

Results of shoulder replacement are excellent for pain relief.  Some surgeons prefer to replace half the joint (hemi-arthroplasty) and some surgeons replace both sides of the joint (total shoulder).  There are advantages and disadvantages of both. The anatomy of the bone, age of the patient and functional requirements are considered when choosing between the type of surgery.  Recently, resurfacing techniques have gained in popularity and showing promising outcomes.  These surgeries are bone-preserving requiring less bone resection and can be used for both hemi-arthroplasties and total shoulder arthroplasty.

Shoulder replacement usually requires an overnight stay in the hospital.  Supervised physical therapy and rehabilitation equipment is prescribed for 6 weeks to 3 months focusing on shoulder motion and strength. 

Office consultation includes a thorough history and physical examination. If warranted, X rays and CT scans may be ordered.  Diagnosis and implementation of treatment can occur within 2 weeks of the initial office visit.
