-PURPOSE OF THE STUDY - To evaluate the results of primary total hip
replacement with Pinnacle (Depuy) acetabular hip at a minimum of 3 years of followup.
- MATERIAL AND METHODS - A total of 48 patients, with 48 hips, undergoing
hip arthroplasty with the use of Pinnacle hip between 2007 and 2009 were evaluated.
The group comprised of 25 men and 21 women with an average age of 67 years
(range, 48 to 81) at the time of surgery. The clinical outcome was assessed by the
Merle d’Aubigné and Postel score and the Harris hip score, and the radiological
results were evaluated on anterior posterior X-ray films of the pelvis and the affected
hip.- RESULTS - The average follow-up was 2.5 years. The average Merle dAubign
and Postel score and Harris hip score was 15 and 85 post-operatively. No
complications were seen. - DISCUSSION - Benefits of using Pinnacle hip system are
1. Range-of-Motion-allows for use of a larger femoral head providing for greater
range of motion. 2. Stability-use of larger femoral head also lowers risk of dislocation.
3. Longevity-offers a lower risk of inflammation and implant loosening. -
CONCLUSIONS - The Pinnacle hip system shows good results at 3 year follow-up
period. The current standard for hip resurfacing is a metal-on-metal bearing with
fixation of the femoral component with cement and cementless acetabular fixation. It
would be valuable to report the midterm results (at an average of seven years) of
cementless Pinnacle hip resurfacing.
