[Prevention of osteoporosis around hip prosthesis using bisphosphonate].

Possible usage of bisphosphonate in total hip arthroplasty (THA) has been described. Recently, clinical efficacy of bisphosphonate in preventing stress-shielding induced disuse osteoporosis around THA has been demonstrated. Bisphosphonate is expected to improve durability of THA. However, clinical relevance of usage of bisphosphonate in THA has not been established and requires further research.
