This study looks retrospectively at 113 patients with low back pain referred by orthopaedic surgeons for bone scanning. 79 scans (70%) were reported normal and 34 scans (30%) abnormal. 61 out of the 79 patients with normal scans were diagnosed and managed as "chronic back strain". Negative bone scans were also encountered in 3 patients with degenerative disease, 3 with prolapsed intervertebral disc and one with spondylolysis. In those patients with positive scans, a varied range of diagnoses was encountered, the main ones being bone metastases, previous trauma, osteomyelitis and degenerative disease. The scan was shown to be helpful in deciding on the presence or absence of pathology, and in identifying the sites of involvement, but not the nature of the disease. A higher likelihood of positivity is seen in the more elderly patients as well as those below 20 years of age. In interpreting the scan, the clinical context is important e.g. a history of trauma, previous surgery or of malignant disease. The bone scan may be normal in disc prolapse and in degenerative disease of the spine.
本研究回顾性观察了113例因腰背痛由骨科医生转诊进行骨扫描的患者。79次扫描（70%）报告为正常，34次扫描（30%）异常。79例扫描正常的患者中，61例被诊断为“慢性背部劳损”并进行相应处理。3例退行性疾病、3例椎间盘突出症和1例椎弓峡部裂患者的骨扫描结果也为阴性。在扫描结果为阳性的患者中，诊断结果多样，主要包括骨转移、既往创伤、骨髓炎和退行性疾病。结果表明，骨扫描有助于确定是否存在病变以及确定受累部位，但无法确定疾病的性质。年龄较大的患者以及20岁以下的患者扫描结果为阳性的可能性更高。在解读扫描结果时，临床背景很重要，例如创伤史、既往手术史或恶性疾病史。椎间盘突出症和脊柱退行性疾病患者的骨扫描结果可能正常。
