成软骨细胞瘤的诊治分析

Diagnosis and treatment of chondroblastoma

目的 总结成软骨细胞瘤的临床诊断要点和治疗经验.方法 回顾性分析1992年6月至2003年2月经病理证实的成软骨细胞瘤16例患者的临床资料.肿瘤部位：股骨下端6例,股骨大粗隆1例,胫骨上端6例,肱骨上端2例,距骨1例.主要症状为关节肿胀、疼痛.16例均经手术治疗.手术方式为彻底刮除病灶＋自体髂骨植骨.结果 12例患者获得随访,随访时间6个月至5年（平均3.5年）,植骨全部融合.1例术后2年复发,行再次刮除植骨,随访6个月未再复发.关节功能除1例股骨远端患者膝关节屈曲稍受限外余全部正常.结论 掌握成软骨细胞瘤的临床特点及影像学特征,有助于减少误诊,正确治疗.手术彻底刮除可达到满意的局部控制.术后经过康复锻炼,病变肢体可获得满意的功能结果.

Objective To summarize the keypoints of clinical diagnosis of chondroblastoma and the experience on the treatment Methods The clinical materials of 16 cases（11 males,aged from 12 to 26 years）from June 1992 to February 2003 of pathologically diagnosed chondroblastoma were analyzed retrospectively. The tumor located at distal femur in 6 cases,great trochanter in 1 case,proximal tibia in 6 cases,proximal humerus in 2 cases, talus in 1 case. The main symptoms were swelling and painful joint. All the 16 cases were treated with curettage and autologous bone graft from iliac crest. Results Twelve cases were followed up for 6 months to 5 years .averaging 3. S years. All the bone graft healed well. One case., recurred 2 years after the initial curettage and was treated with curettage again. No recurrence occurred at the last follow-up 6 months after the second curettage. The function of the involved joints was nearly normal in all cases except for one case with slight limitation of knee flexion. Conclusions Mastering the image and clinical characteristics of chondroblastoma can avoid misdiagnosis and mistreatment Curettage can control the tumor satisfactorily. Postoperative rehabilitation can improve the function of the involved limb.
