Aims: Minimal invasive surgery is now possible for hip replacement. We present our system (called the SE Hip SystemTM). It is a universal system and is here used with the LINKTM C.F.P stem and T.O.P cup.

Methods: We have used this system on forty patients. It involves five steps. One (incision) – a single 5cm. postero-lateral incision; two (neck cut) – application of a cutting block to the femoral neck and removal of the head; three (broaching the femur) – preparation of the femur; four (reaming the acetabulum) – ream using the modified reamers and precisely place the cup with the lollipop device; five- place the stem and soft tissue balance with the spacers. The hip is then reduced and the wound closed.

Results: The average pre-operative Harris hip score was 28.64; the average post-operative score was 82.65. Complications included one transient sciatic nerve palsy. Average blood loss was 250 mls, the average time in hospital was 3 days and the average number of physiotherapy sessions required was 4.

Conclusions: Minimal invasive hip surgery is now possible. There is a markedly reduced cone of dissection. Navigation systems and intra-operative imaging are not required. This technique should minimize maltracking (and wear) and shorten the recovery period allowing the possibility of day or outpatient hip surgery.
