Abstract
The good clinical results in hip arthroplasty have led to an increasing
number of joint replacements in younger patients. Regardless, it is well
known that this patient group faces an increased risk of early implant
failure, which is probably related to their higher activity level.
Early cementless implants obtained reproducible fixation distally.
However this was associated with thigh pain, and the proximal offloading
predisposed to stress shielding with loss of proximal bone stock.
All these issues are addressed by conservative implants. In order to
facilitate potential revision surgeries, bone-preserving implants, such as
hip resurfacing arthroplasty (HRA) and short stem arthroplasty (SHA)
implants, have been developed and recently have gained increasing
popularity.
A comparative study between short stem and standard cementless stem
in the treatment of young patients with osteoarthritic hips was done and
revealed that short stems are as effective as standard stems in relieving
pain and improving function. And the complications were similar to that
in the literature.
