Hip Resurfacing

Hip Resurfacing

Modern hip resurfacing was introduced in 1990s as an alternative for standard total hip replacement (THR) in younger patients. This procedure has following differences compared to a standard THR.

Conventional hip replacement
Hip resurfacing
1. More bone is removed from the top of the thigh bone ( head and neck about 6-8 cm)
Less bone is removed 1-2cm only. That means you will retain more bone. It will be easier if future reoperation is required.

2. Usually performed for older patients
Usually performed for younger patients
Femoral canal violation
Femoral canal left intact.

3. Metal on polyethylene, metal on metal or ceramic on ceramic articulation
Metal on metal articulation

4. Risk of dislocation about 3%
Lesser risk of dislocation.

5. Leg length discrepancy.
Minimal or no leg discrepancy

6. Thigh pain
No thigh pain

Metal on metal hip resurfacing produces metal ions which circulate in the blood. No definite adverse effects from these metal ions have been shown so far. However, resurfacing is not generally advocated in young and child bearing women. There is also a small risk of hip fracture following this operation and hence not recommended in women over 60 years and people suffering from osteoporosis.
