A prospective study was performed with 97 patients who had undergone total hip replacement surgery and who were not experiencing pain or other symptoms or problems. The study was intended to determine the normal postoperative appearance of radionuclide scans of the hip following administration of technetium-99m methylene diphosphonate. Five areas of the prostheses were evaluated. Results showed that 6 months after implantation activity around the lesser trochanter and prosthesis shaft became insignificant. Activity around the acetabulum, greater trochanter, and prosthesis tip stabilized approximately 2 years after surgery; approximately 10% of patients in the study had persistent activity in these areas. Familiarity with this normal progression is fundamental to interpretation of postoperative bone scans in patients with total hip prosthesis.
对97例行全髋关节置换术且无疼痛或其他症状及问题的患者进行了一项前瞻性研究。该研究旨在确定给予锝-99m亚甲基二膦酸盐后髋关节放射性核素扫描的正常术后表现。对假体的五个区域进行了评估。结果显示,植入后6个月,小转子和假体柄周围的活性变得不明显。髋臼、大转子和假体尖端周围的活性在术后约2年趋于稳定;该研究中约10%的患者在这些区域有持续活性。熟悉这种正常进展对于解读全髋关节假体患者的术后骨扫描至关重要。
