Hip resurfacing: expectations and limitations

Physical Therapy Following a Hip Resurfacing Procedure

“…Similar findings were revealed in a five year postoperative follow-up showing superior results in patients with HR versus THA [33]. In studies with a similar time frame, conclusions supporting HR in younger patients were published and it was noted that HR and THA have similar survivorship rates [34].…”

Histological, histomorphometric and microtomographic analyses of retrieval hip resurfacing arthroplasty failed at different times

“…HR may present benefits over total hip replacement because femoral bone stock is maintained, there is reduced wear compared with high density polyethylene, it has a large femoral head that could be reduced dislocation rate, it is said to offer the patient increased levels of postoperative activity and is easy to convert into a stemmed prosthesis [2]. The general opinion about this procedure is mainly divided into a favorable one advocated by McMinn et al [3] and a negative one supported by Spierings et al [4]. The mid-term results of Birmingham Hip Resurfacing (BHR) suggest a survival rate of about 98% at five years.…”

“…However, Spierings et al still consider resurfacing as an experimental design for investigational use only, until long-term follow up confirms its superiority in comparison with total hip replacement [3,4]. Recently various complications, such as femoral neck fracture [5-7], avascular necrosis [8,9] and pseudotumour formation [10,11], as well as unexplained pain, aseptic loosening [12], and osteolysis [4] have been reported. To improve the technique and the success of the treatment, experimental preclinical models can be used to allow the evaluation of biomechanics, biocompatibility, bioactivity and biofunctionality on innovative biomaterials, prosthetic devices and combined therapies.…”
