To evaluate the radiological features of osteoid osteoma around lesser trochante of femur, and to analyze the outcomes of treatment with open surgery. Methods: From July 2013 to August 2015, 14 patients (9 males, 5 females) with osteoid osteoma around lesser trochanter were retrospectively reviewed. The ages of patients were 9-44 (average 20) years old. The duration of symptom was 3-36 (average 8) months. After the X-ray plain radiography, CT and MR, all patients underwent open resection. No intense exercise was allowed in the first three months after the operation. Results: There were 9 cases of cortical type, and 5 cases of subperiosteal type. The niduses were found by plain radiographs in 9 patients. By CT scan, the niduses were found in all 14 patients. The average pre-operative visual analogue scale (VAS) without NSAIDs was 6.5. One month after the operation, the average VAS was 0 for all patients. The follow up time for all patients was 9-34 (average 20) months. No recurrence, infection, neurovascular injury or fracture was found during the follow up. Conclusion: Open resection is a feasible method for osteoid osteoma around lesser trochanter of femur with satisfied outcome and low complication rate.
评估股骨小转子周围骨样骨瘤的影像学特征，并分析开放手术治疗的效果。方法：回顾性分析2013年7月至2015年8月收治的14例股骨小转子周围骨样骨瘤患者（男9例，女5例）。患者年龄9 - 44岁（平均20岁），症状持续时间3 - 36个月（平均8个月）。经X线平片、CT及磁共振成像检查后，所有患者均接受开放切除术。术后前三个月不允许剧烈运动。结果：皮质型9例，骨膜下型5例。9例患者经X线平片发现瘤巢，14例患者经CT扫描均发现瘤巢。术前未使用非甾体抗炎药时视觉模拟评分（VAS）平均为6.5分。术后1个月，所有患者VAS平均为0分。所有患者随访时间9 - 34个月（平均20个月）。随访期间未发现复发、感染、神经血管损伤或骨折。结论：开放切除术是治疗股骨小转子周围骨样骨瘤的一种可行方法，疗效满意，并发症发生率低。
