RESURFACING	TOTAL HIP REPLACEMENT
Only diseased cartilage and a small surrounding area of the femur are removed, to be replaced with new surfaces.	The head and neck of the femur are removed, and the implant is a press fit in the femoral canal.
Bone preserving Beneficial to younger, more active patients Better prospects for future revision Best replicates pre-existing anatomy	Long term results positive Less restrictions on patient suitability Comparatively better range of motion

'Minimally Invasive Surgery is total or partial hip surgery that can be carried out through an incision of less than 10cm without disrupting soft tissues or compromising acetabular component positioning.'

Mr G S Chana F.R.C.S. Ed Orth, Consultant Orthopaedic Surgeon, Royal Orthopaedic Hospital, UK.

Conventional open hip surgery techniques have been well described through incisions of around 25cm. Many hip resurfacing and THA procedures today show post-operative incisions of such sizes.

Mini-incision surgery is the technique of shortening the conventional operative field to approximately 15cm, sometimes less depending on the skill of the surgeon.

When one miniaturizes the incision of the conventional open approach (mini-incision surgery), many complications can occur

• Skin and muscle damage- due to extended pulling on the soft tissues.
• Leg length discrepancy- due to poor visualisation of the anatomy.
• Fractures- incorrect implantation of the femoral or acetabular components are key causes of fractures.
• Component malposition- due to poor visualisation of the anatomy.

Consultant surgeon Mr Gursharan Singh Chana, along with the orthopaedic device expertise of Comis Orthopaedics, developed the Minimally Invasive Surgical technique, implants and instrumentation for hip resurfacing and total hip arthoplasty that overcome the issues associated with mini-incision surgery.

The MIHR^® resurfacing and modular implants along with their instrumentation were created from initial concept for use with the modified posterior MIS technique. This system provides a host of advantages to the patient:

• Less post-operative pain.
• Less muscle damage.
• Correct positioning of implants ensured by instrumentation developed alongside
  Mr G Chana.
• Shorter hospital stay.
• Lower blood loss.
• Smaller incision.
• Quicker return to work and functional activities.

Patient Testimonials

Mr David Arthur - Left hip operated on 15/07/03
Comments: Magic result. No pain after the operation, little discomfort once the drain was removed, and a couple of days of physiotherapy. As I bought an automatic car, and the left hip had been operated on I was able to drive early and was back at work after 10 days.

Mr Leslie Ernest Woodley - Left hip operated on 09/09/05
Comments: Absolutely perfect. No pain, total mobility. Can you replace the rest of my body?
