Brief summary

The objectives of this study are to assess the bone ingrowth after total hip arthroplasty using the "Short Mini Stem".

Interventions

Total Hip Arthroplasty - The "Short Mini Stem" is a total hip replacement system consisting of lightweight titanium alloy inserted using a minimally invasive surgical (MIS) approach. The "Short Mini Stem" is shorter than conventional hip stems, which allows the stem to conserve more of the patient's thigh bone (femur) than other prostheses and requires a smaller skin incision. The approximate duration of the hip arthroplasty procedure is one hour.
