Purpose: Fibrous dysplasia is related to the mutation of gene encoding the alpha-subunit of a signal-transducing G-protein and has variable clinical course. Operation can be performed to prevent functional disorder or structural deformity. After curettage, autologous bone graft were used to fill the defects after curettage. The aim of this study is to compare the result of autogenous cancellous bone grafting and allogenic bone grafting for fibrous dysplasia. Materials and Methods: Among the patients who visit our hospital during the period of April, 1997 to October, 2013, we selected 34 patients who diagnosed fibrous dysplasia and visited our clinic over 1 year. There were 13 males and 21 females. Average age was 26.4 (range 2 to 57) years old. Autogenous bone graft (group I) in 5 cases, Non-autogenous bone graft (group II) in 30 cases. Iliac bone is used in all cases of autogenous bone graft. There were no significant difference in age, follow-up period, preoperational laboratory finding between two groups. Radiographic image was done to evaluate the recurrence of fibrous dysplasia or secondary degeneration. Results: There were four cases in recurrence (group I: 1 case, group II: 3 cases, p=0.554). In all recurrent cases, reoperations were done using curettage and autogenous iliac bone graft. There was no re-recurrence after reoperation. One case of secondary aneurysmal bone cyst was confirmed (group II) and 1 cases of pathologic fractures had developed (group I: 0 case, group II: 1 cases, p=0.559). No malignant change occurred. Conclusion: There were no significant difference between autogenous bone graft group and non-autogenous bone graft group. Our result suggested that autogenous bone graft seems to be good method to treat fibrous dysplasia, in the case of small volume of tumor lesion or non-weight bearing portion.

A seven-year-old Yorkshire terrier 2.1 kg was admitted with a 2 months history of sever bilateral forelimb lameness and joint instability. Examination and radiographs revealed caudal luxation of bilateral antebrachiocarpal joint. Luxation of bilateral antebrachiocarpal (ABC) joint in a toy breed dog was treated with pancarpal arthrodesis. Modified external skeletal fixator (ESF) (type IIb) with polymethylmethacrylate (PMMA) was utilized in this case. Porcine cancellous bone graft (PCBG) was inserted to fill the joint space in carpus. The clinical and radiographic assessments of joint after the surgical procedure proved that PCBG can be used a promising alternative to Autogenous cancellous bone graft (ACBG).

The authors reviewed 49 cases(48 patients) of benign bone tumor who had surgical treatment with xenograft at department of orthopedic surgery, Seoul National University Hospital from May, 1980 to May, 1994. Materials consist of 21 males and 27 females. The mean age at operation was 20.1 years(range : 4 -55 years) and the mean follow up period was 25.4 months(range : 7 - 85 months). We did xenograft only in 34 cases and xenograft mixed with autograft in 15 cases(14 cases, from ilium, 1 case from femur). The used materials for xenograft were $Lubboc^{(R)}$ in 29 cases, $Surgibone^{(R)}$ in 17 cases and $Pyrost^{(R)}$ in 3 cases. The average durations when bony union was achieved in radiograph were 13.8 weeks in whole cases, 12.5 weeks(range : 8 - 24 weeks) in $Lubboc^{(R)}$ graft cases and 15.7 weeks(range : 6 - 24 weeks) in $Surgibone^{(R)}$ graft cases. The tumor recurred in 4 cases, 1 case was recurred giant cell tumor at distal femur treated with mixed auto and $Lubboc^{(R)}$ graft and 2 cases were large cystic lesions at the proximal humerus diagnosed as simple bone cyst and at distal tibia diagnosed as fibrous dysplasia treated with $Surgibone^{(R)}$ graft and 1 case was aneurysmal bone cyst of the proximal tibia treated with $Lubboc^{(R)}$ graft. Wound infection occurred in 1 case. More transfusion was done in the cases that the lesion was larger than 5cm, the lesions were in the ilium or femur and the cases that were treated with mixed with autograft. This study implies that benign bone tumor is successfully treqated with curettage and xenograft or xenograft mixed with autograft. And also this method will reduce morbidity of donor site, intraoperative bleeding and post-transfusion complications.

Although chondrosarcoma is a common primary malignant bone tumor, its occurrence in the spine is very rare. It is also well known that even after complete removal of chondrosarcoma in bone, not a few recurrence is possible. Surgical cure of a spinal chondrosarcoma is even more difficult because total excision of chondrosarcoma is usually impossible in the spine. No patients with spinal chondrosarcoma surviving more than 18 years has been reported in literature. We are reporting one patient(32 year old housewife) with chondrosarcoma at the $12^{th}$ thoracic spine which was treated with complete corpectomy of the $12^{th}$ thoracic vertebral body and rib and cancellous bone graft fixed with plating. She was followed for more than 3 years without local recurrence or distant metastasis.
