Twenty-nine cases of unicameral bone cyst developed in long bone of children have been treated and followed up for 4.5 years in average form Department of Orthopaedic Surgery, Guro Hospital, Korea University, College of Medicine since September, 1983, Treatment for those lesions differed to form largely two groups, one of which consised of insillation of Methyl-prednisolone for non-weight bearing bones(12 humeri) and the other of curettage and autogenous bone graft for weight-bearing bones(7 femur). Methl-prednisolone group required repetition of instillation for 3.5 time in average spanning over 4 years until cloudy obliteration occurs. Curettage and bone graft had healed in 3 year 6 months' time in average. There were neither recurrence nor pathologic fractures of the lesions with the latter group. Immobilization period was virtually non with Methyl-prednisolone group and 4-6 weeks by hip spica with curettage and bone graft group. As conclusions, It seems confirmed that treatment strategy of unicameral bone cyst consisted of Methyl-prednisolone instillation for humerus lesions and early curettage and bone graft for femur lesions is applicable as guideline having solid ground in clinical experiences.

Giant cell tumor is most frequently found in juxtaarticular region, and difficult to treat because of local recurrence. Although primary resections reduce recurrence, the joint function will be markedly impaired. Techniques involving physical adjuncts(high speed burr and electric cauterization), acrylic cement or en bloc resection with VFG(vascularized fibular graft) have been employed to reduce local recurrence. From October 1984 to April 1994, twenty-nine patients diagnosed as giant cell tumor were treated at department of Orthopaedic Surgery, School of Medicine, Kyung Hee University. There were eleven men and 18 women, ranging in age from 17 to 52 years(mean: 34 years). The average follow-up period was four years and five months. The location of the lesion was around the knee in 15, distal radius in three, femoral head in three, and others in eight patients. Fifteen patients around the knee joint were treated with several modalities; curettage with bone graft in five, curettage with cement filling in three, curettage with bone graft and physical adjuncts in five, en bloc resection with VFG in one and en bloc resection with arthroplasty in one patient. The functional results, according to the Marshall's knee score, were excellent in one, good in two, and fair in two after the curettage with bone graft, good in three after the curettage with bone cement filling, excellent in one, good in four after the curettage with bone graft and physical adjuncts, and good in two after the en bloc resection with VFG or arthroplasty. Three patients had local recurrence among 15 patients with giant cell tumor around knee. Vascularized fibular graft around wrist joint provided good functional restoration without local recurrence in all three patients who had giant cell tumor in distal radius. Although there is no statistical significance, it seems that curettage with bone graft using physical adjuncts or acrylic cement reveals better results than simple curettage with bone graft. Excellent functional result were obtained without local recurrence by using vascularized fibular graft after en bloc resection.

Purpose: The purpose of this study is to report the result of endoscopic assisted curettage and bone graft for the treatment of simple bone cyst in the calcaneus. Materials and Methods: Three cases in three patients who had curettage and bone graft of simple bone cyst in the calcaneus under endoscopic view were prospectively reviewed. A minimum follow-up of 1 year was required for entrance into the study. The results of treatment were clinically and radiologically assessed. Results: One case with preoperative heel pain gained complete relief of the pain at postoperative four weeks. All three cases had radiological union of grafted bone at an average of thirteen weeks after the operation. Shortened hospitalization and decreased postoperative pain were remarkable. Complications such as infection, skin necrosis, nerve injury, and, fracture were not seen. There was no evidence of the recurrence of the cyst in all three cases. Conclusion: Endoscopic assisted curettage and bone graft of simple bone cyst in the calcaneus is thought as an effective alternative procedure avoiding the possible complications of the classic method.

Chondroblastoma is a rare benign cartilaginous neoplasm that accounts for 1% of bone tumors and is common in the epiphysis of the long bones. The condition is rarely found in the talus bone (4% of cases). This paper reports a 15-year-old male patient treated for a talus bone lesion discovered incidentally on imaging. Excisional biopsy, curettage, and an autobone and allobone graft were performed, with good results.

Between Sep. 1986 and Mar. 1996, twenty four patients with recurrent giant cell tumor of their long bones were treated and followed up for more than two years. We applied three different modalities for treatment: curettage with bone graft, curettage and packing with polymethylmethacrylate, wide excision with or without reconstruction. During the average 51.5 months after operation(24-97 months), two of three patients who underwent curettage with bone graft showed recurrence. Patients who underwent wide excision showed no recurrence. Five of fifteen patients who underwent curettage and packing with polymethylmethacrylate showed recurrence. Four of seven who showed recurrence were treated with reapplication of curettage and packing with polymethylmethacrylate. All four patients showed no recurrence, and two of them have been followed up for more than two years. We suggest that the curettage and packing with polymethylmethacrylate is an effective treatment modality of the recurrent giant cell tumor.

비교적 흔한 골의 양성 질환으로 소파술 및 골 이식술, 절제술, 스테로이드 또는 골수 주입법 등이 일반적으로 시행되는 단순 골낭종은 비교적 낮은 빈도로 종골에 발생하게 되며, 종골에 발생 시, 기존의 스테로이드 주입술보다는 관혈적 소파술 및 골 이식술이 주로 시행된다. 저자들은 9세 남아에서 발생한 종골의 단순 골낭종에 대해 최소 침습적 술기를 통한 내시경적 소파술 및 골 이식술을 통해 좋은 결과를 경험하였기에 문헌 고찰과 함께 보고하고자 한다.

Chondroblastoma is an uncommon neoplasm in bone, occurring at the epiphysis or apophysis of growing long bones and is known to have a recurrence rate of around 10% after surgical treatment. We reviewed 14 patients of pathologically proven chondroblastoma, who were surgically treated, from December 1987 to August 1997. The location of tumors was proximal femur in 4 cases, distal femur in 4 cases, proximal tibia in 2 cases, patella in 1 case, proximal humerus in 1 case and calcaneus in 1 case. The most common complaint was pain. In all nine cases in which MRI was performed, the MR imaging showed a lobulated low signal intensity(SI) rim. Low SI foci within the tumor were present in 4 of 9 cases and corresponded to calcification seen on radiographs or CT. Bone marrow edema was also present in 4 of 9 cases on MR imaging. The average duration of follow-up was 2 years, 5 months, ranging from 1 year to 7 years, 2 months. Twelve patients were treated by curettage and autogenous bone graft, one by curettage only, and one by curettage and bone cementing. Two cases which showed local recurrence were treated with curettage and bone graft. Two recurred cases had the presence of bone marrow edema on MR imaging. The presence or absence of bone marrow edema may be a useful indication of tumor activity, although further study will be required.

The results of treatment of eighteen lesions of fibrous dysplasia which of them seventeen lesions were treated with surgery were reviewed at the Department of Orthopedic Surgery, College of Medicine, Hanyang University Hospital. We studied to evaluate the functional clinical results and the recurrence according to the type of disease, grafted bone, methods of treatment and location of lesion. We treated sixteen patients(five males and eleven females) and their mean age was 22.6 years. There was no association with skin pigmentation or dysfunction of endocrine system. Twelve patients had a monostotic pattern and four patients had a polyostotic pattern. Twelve lesions were treated with curettage and bone grafting and four lesions in the proximal femur were treated by internal fixation with curettage and bone grafting. One lesion was treated by en-bloc resection. There were eleven satisfactory results in twelve monostotic lesions and there were four satisfactory results in five polyostotic lesions, but the recurrence were four cases, respectively. The two unsatisfactory results were seen in two patients treated by autografting, but there were three recurrence of four lesions in autografting only, one of five in autografting and allografting, four of eight in allgrafting or xenografting. Four of six lesions in upper extremity were recurred after curettage and bone grafting and five of them showed satisfactory results. In pelvic and lower extremity lesions, the recurrence were occurred in two lesions after curettage and bone grafting and in two lesions after internal fixation and bone grafting. The recurrence does not always provide an unsatisfactory functional results and the recurrence showed higher rate in radiologic pattern of ground glass appearance with-out marginal sclerotic rim, but the recurrence according to grafted bone showed similar rates. Curettage and bone grafting is adequate for a symptomatic lesion and firm internal fixation is needed for a lesion in proximal femur. In use of grafted bone, xenograft or allograft may be preferable to autograft because of the disadvantage of autografting like a increased blood loss, prolonged operation times, etc.
