Medium-term results of the Charnley low-offset femoral stem
|
A reduced femoral offset in total hip replacement has been thought to be disadvantageous. We reviewed the results of 54 consecutive primary total hip replacements in 49 patients (mean age of 68 years) performed between August 1990 and December 1994, with a mean follow-up of 8.8 years (SD 2.1). The mean pre-operative femoral offset for these hips was 41 mm (SD 7.4). All patients received a low-offset Charnley stem and a polyethylene cup inserted by a single surgeon.

The femoral head/neck offset and hip resurfacing
Journal of Bone and Joint Surgery
; Because the femoral head/neck junction is preserved in hip resurfacing, patients may be at greater risk of impingement, leading to abnormal wear patterns and pain. We assessed femoral head/neck offset in 63 hips undergoing metal-on-metal hip resurfacing and in 56 hips presenting with non-arthritic
