ABSTRACT

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.
