目的:探讨关节内骨样骨瘤的诊断和关节镜手术治疗经验。方法:回顾性研究我所于2006年3月～2009年6月手术治疗的7例关节内骨样骨瘤患者。患者平均年龄22.4(11～32)岁。术前均进行薄层CT检查确定诊断和进行手术定位。治疗采用关节镜下定位肿瘤位置,刮勺取出瘤巢。结果:从出现临床症状到确定诊断之间的平均时间为26个月(18～36个月)。术后平均随访时间19个月,患者症状较术前明显改善,表现为VAS评分下降,无复发,疼痛缓解,活动范围正常等。结论:关节内的骨样骨瘤由于不典型的临床症状和平片表现常常导致确诊时间延长。采用关节镜治疗关节内的骨样骨瘤是一种安全有效的方法。
Objective: To explore the diagnosis of intraosseous osteoid osteoma and the experience of arthroscopic surgery. Methods: We retrospectively studied 7 cases of intraosseous osteoid osteoma who underwent surgery in our department from March 2006 to June 2009. The average age of patients was 22.4 (11 ~ 32) years old. Thin layer CT examination before surgery to determine the diagnosis and surgical positioning. Treatment using arthroscopic tumor location, spatula remove the nests. Results: The mean time from the onset of clinical symptoms to the definitive diagnosis was 26 months (18-36 months). The mean follow-up time was 19 months. The symptoms of the patients were significantly improved compared with that before the operation. The VAS scores decreased, no recurrence, pain relief and normal range of activities were observed. CONCLUSIONS: Osteoid osteoma in the joint often leads to prolonged diagnosis due to atypical clinical symptoms and plain film findings. Arthroscopic treatment of osteoid osteoma in the joint is a safe and effective method.
