“…There are a number of theoretical advantages of hip resurfacing over conventional THA, including preservation of bone stock [1,20,64], less stress shielding [47], less thigh pain [88], fewer dislocations [26,87], reduced osteolysis [87], improved biomechanics [44,81,89], retention of proprioception, and ease of revision in comparison to THA [1,14,64,75]. Clinical disadvantages of hip resurfacing include the risk of femoral neck fracture [6,63], component malpositioning secondary to increased surgical complexity [20,24], femoral component loosening [5,8,18], decreased head-neck offset causing impingement [22,24], and metal ion production [36,59].…”
