SPAIRE
Surgeons can access the hip through several different approaches. The posterior, anterior and lateral approaches are the most common. Each approach works well. However, each also has relative advantages and disadvantages.
Dr Woodbridge has completed fellowship training in a tendon-sparing modified posterior approach. It is called the S.P.A.I.R.E. (Spare Piriformis And Internus, Repair Externus) approach.
A standard posterior approach is the most versatile option. It involves detaching the small muscles from the back of the femur. These are the short external rotators. The surgeon then repairs them to the bone at the end of the procedure.
In contrast, the less-invasive SPAIRE approach preserves the piriformis and obturator internus tendons. It also preserves the surrounding gemelli muscles. Dr Woodbridge received fellowship training in this technique with Professor Timperley. Professor Timperley first developed the approach at the Exeter Hip Unit in England.
Advantages of SPAIRE
The main advantage of the SPAIRE technique is improved stability of the joint. This may reduce the risk of dislocation. Patients who have their hip replacement through the SPAIRE approach do not need to follow traditional postoperative hip precautions. This simplifies the rehabilitation process.
There may also be additional strength and functional benefits with this tendon-sparing approach. However, further research studies may be required to confirm these benefits.
In some cases, preservation of the short external rotators may impair visualisation of the socket (acetabulum). In this situation, the SPAIRE approach can be easily converted to a standard posterior approach.
Dr Woodbridge will be happy to discuss whether the SPAIRE approach is appropriate for your hip replacement. Contact the rooms on (02) 8785 5422 or contact us using the form on our Contact Us form.
