Partial shoulder replacement, also known as a hemiarthroplasty, is a surgical procedure performed to replace only one part of the shoulder joint. It involves replacing the damaged or diseased humeral head (the ball-shaped part of the upper arm bone) with a prosthetic component while preserving the existing socket (glenoid).
Partial shoulder replacement is typically recommended for patients who have severe arthritis or a fracture of the humeral head. It is commonly performed in cases where the glenoid (socket) is still healthy and does not require replacement. The procedure aims to restore pain-free movement and function to the shoulder joint.
During the surgery, the orthopaedic surgeon, Dr Rajesh Malhotra, makes an incision and carefully removes the damaged portion of the humeral head. The prosthetic component, which consists of a metal ball attached to a stem, is then inserted into the prepared bone. The prosthetic ball articulates with the existing socket, allowing for improved joint movement.
Recovery from partial shoulder replacement surgery typically involves a period of immobilisation and rehabilitation. Patients may need to wear a sling or brace for several weeks to protect the healing joint. Physical therapy is an essential part of the recovery process and helps regain strength, flexibility, and range of motion in the shoulder.
It's important to note that the decision to undergo partial shoulder replacement is based on individual circumstances and the advice of a qualified orthopaedic surgeon. Dr. Rajesh Malhotra considers factors such as the extent of the damage, the overall health of the patient, and the potential benefits and risks of the procedure.
