Total Hip Replacement

Hip replacement was developed by Sir John Charnley in the 1960’s and it has been described by some as the most successful operation of the 20th century.  Since then there have been many advances in both the surgical technique and manufacturing processes. In addition patients and health economists want shorter hospital stays, faster recovery times and longer lasting implants.

Nowadays there is a huge array of implants and surgical approaches. In general the components can be cemented or uncemented and the bearing surface can be metal on poly, ceramic on ceramic or metal on metal. We believe it is essential that the pros and cons of each of these options are fully explained. A final decision is mutually agreed with you based on several factors including: your age & general health, the quality of your bone and your functional demands.

There has been a lot of media interest in the mini-incision hip replacement and the Birmingham hip. Mr Pollock Is trained in the use of both these techniques and will be happy to discuss them with you. Some examples of the various types of total hip replacement are illustrated below.

Clinical Examples

A 73 year old man with a painful arthritic hip has had a cemented total hip replacement similar to the type originally designed by Charnley. This hip would be expected to survive for about 15 years.

 

 

 

A forty year old man who had previous surgery to his hip now has arthritis combined with abnormal alignment of the hip. The joint had to be replaced and at the same time the alignment had to be corrected. He was given a custom made hip replacement manufactured at the Centre for Bio-medical Engineering based at the Royal National Orthopaedic Hospital. A successful outcome was achieved.

 

A 50 year old woman with arthritis of the hip due to avascular necrosis. She is a keen hill walker. She was given an uncemented hip with a large metal on metal bearing surface. This has the advantages of giving her increased stability for walking on uneven ground and should last longer than a conventional cemented hip.
