Planning for joint replacement surgery requires careful consideration of your circumstances. This involves a thorough history, examination, blood tests, shoulder x-rays and a ct scan to assess the bone structure of your joint. In some circumstances an MRI scan to assess your rotator cuff is required. In addition to this, Dr McBride uses 3D planning technology to plan your operation prior to surgery. This allows pre-surgical prediction of implant sizes and placement, the designing of guides for surgery, improved precision of surgery and pre-operative estimation of post operative range of motion. This technology and its applications are evolving at a rapid pace.
Total shoulder replacement is a surgical option for patients suffering osteoarthritis and other conditions in the shoulder. It is an open procedure which involves replacing the shoulder joint with a specially designed prosthesis. The goal of this surgery is to provide a stable, pain free, functional shoulder joint with good range of motion to allow you to live an active lifestyle.
The prosthesis consists of two components. The first is a humeral head component. This is usually a metal surface that is secured into the humeral bone.Traditionally, to secure the head surface to the humerus a long stem was required. Advances over the last ten years in prosthetic construction and design now allow the humeral head to be fixed in most cases with a short stem or “mid head”. This preserves bone while maintaining the same strength of fixation and survivorship.
During total shoulder replacement, the shoulder socket (glenoid) is also refsurfaced with a polyethelene component cemented to the shoulder socket. An all polyethelene cemented glenoid component has been proven by the Australian Orthopaedic Association National Joint Replacement Registry to have the best survivorship compared to other types of glenoid replacement. We only use prosthetic components and options with proven survivorship on the Australian Orthopaedic Association National Joint Replacement Registry. Furthermore, we participate and conduct research with the registry in shoulder joint replacement surgery to ensure our knowledge continues to advance and patients receive the best evidence based treatment and outcomes.
