Technetium 99Tcm pyrophosphate bone scans were done on 35 patients who complained of persistent hip following total hip replacement. The scans of six patients were normal and the symptoms of these patients either resolved (three) or greatly improved (three) without further treatment. Twenty-nine patients had abnormal scans. Seventeen of these were due to infection or loosening of the prosthesis. Paget's disease of bone, protrusion of the prosthesis and heterotopic ossification also caused scan abnormalities. These causes could not be distinguished from one another on the scan. A radiograph of the hip is essential for interpreting the scan correctly. Scanning of the painful hip prosthesis helps to detect patients in whom serious complications are present or are likely to develop.
对35例全髋关节置换术后持续存在髋部问题的患者进行了锝99m焦磷酸盐骨扫描。6例患者的扫描结果正常，这些患者的症状未经进一步治疗即自行缓解（3例）或显著改善（3例）。29例患者的扫描结果异常。其中17例是由于感染或假体松动。骨佩吉特病、假体突出和异位骨化也导致扫描异常。这些原因在扫描中无法相互区分。髋部X线片对于正确解读扫描结果至关重要。对疼痛的髋关节假体进行扫描有助于发现存在严重并发症或可能发生严重并发症的患者。
