미세수술의 발달과 더불어 악성 및 양성 종양의 치료로서 병소 조직 절제후에 결손부에 혈관 부착 골이식술을 시행하는 골종양재건술이 많이 이용되고 있으나 원래 병소가 이식골에 전이되는 보고는 많지 않다. 본 교실에서는 양성 골종양인 섬유성 골이형성증에서 종양조직 절제술후에 생비골 이식술을 시행한 후, 이식골에 원래 종양이 재발한 예를 체험하였기에 적출술 후 생골이식술로서 결손부를 대치하는 수술시에 충분한 병소의 제거 및 지속적인 추시를 통하여 재발 여부를 확인하는 것이 필요하다고 제안하는 바이다.

Most simple bone cysts are found in the metaphysis of the long bone, such as proximal humerus or proximal femur. Appropriate treatment is aspiration of the cyst followed by instillation of methylprednisolone or curettage with bone graft. We experienced 1 case of the simple bone cyst of the metatarsal bone. This case was treated by curettage and inserting allograft into the defect.

Introduction: Piezosurgery device is one of the most commonly used instrument on the intraoral surgery such as maxillary sinus lift and autogeneous bone graft. Piezosurgery instrument also contains the tips that are manufactured especially for the convenient bone graft, which now many surgeons apply them for collecting bone graft materials in the curettage method for the restoration of skull defects. However, objective data has not been shown concerning the effects about bone graft with using Piezosurgery. Therefore we investigated the effects of Piezosurgery on the rabbit-skull defect healing. Materials & Methods: To investigate the regeneration of the bony defect with various bone graft, 10 adult New Zealand white rabbits (average weight : $2.8{\pm}0.3kg$, about 12weeks) were used. The four circular bony defects measuring 6mm in diameter were made with Piezosurgery device on each rabbit cranial bone. The harvested bone tissues during defect formation were also used for autogeneous bone graft. They were grafted into the defects in a various type; block type (Group 1), particulated type by the bone mill (Group 2), chopped type by curette shaped Piezosurgery tip (Group 3), the defect without any graft was served as control (control group). The animals were sacrificed after 6 weeks and bone regeneration capacity was evaluated histomorphometrically. Result & Conclusion: Autogeneous bone graft harvested using a Piezosurgery instrument showed satisfactory bone regeneration. There was no conspicuous difference bone prepared among by bone mill or Piezosurgery and block bone graft. Therefore, the bone harvested from the intraoral site near the operation field using the piezosurgery device can be a feasible and reliable graft for intraoral bony defects.

Aneurysmal bone cysts are uncommon bony lesions of the spine. Approximately 3-20% of the aneurysmal bone cysts occur in the spine, predominantly in the lumbar region, but they may occur at the any level of the spine. These lesions commonly arise from the neural arch and occasionally invade the pedicle and the vertebral body. The clinical diagnosis of a spinal lesion can be very difficult in the early stages of the disease because specific symptoms and signs are usually absent or only amount to back pain. However, depending on the level of involvement and the extent of neurological compression, a wide variety of neurological symptoms and signs may appear, ranging from mild radicular symptoms to complete paraplegia or tetraplegia. Available treatment options include complete excision or curettage of the lesion with bone graft, but where excision cannot be achieved, low dose radiation or arterial embolization may be used. We report a case of aneurysmal bone cyst in the pedicle of the T10 spine with nonstructural scoliosis of $40^{\circ}$ Cobb's angle which was treated successfully with only curettage of the lesion.

Objectives: Idiopathic bone cavity (IBC) is an uncommon intra-osseous cavity of unknown etiology. Clinical features of IBC are not well known and treatment modalities of IBC are controversial. The purpose of this study was to investigate the clinical characteristics of 27 IBC patients who underwent surgical exploration. Materials and Methods: A total of 27 consecutive patients who underwent surgery due to a jaw bone cavity from April 2006 to February 2016 were included in this study. Nine male and 18 female patients were enrolled. Patients were examined retrospectively regarding primary site, history of trauma, graft material, radiographic size of the lesion, presence of interdental scalloping, erosion of the inferior border of the mandible, complications, results of bone graft, and recurrence. Results: Female dominance was found. Maxillary lesion was found in one patient, and bilateral posterior mandibular lesions were found in two patients. The other patients showed a single mandibular lesion. The posterior mandible (24 cases) was the most common site of IBC, followed by the anterior mandible (5 cases). Two patients with anterior mandibular lesion reported history of trauma due to car accident, while the others denied any trauma history. Radiographic cystic cavity length over 30 mm was found in 10 patients. Seven patients showed erosion of the mandibular inferior border. The operations performed were surgical exploration, curettage, and bone or collagen graft. One bilateral IBC patient showed recurrence of the lesion during follow-up. Grafted bone was integrated into the native mandibular bone without infection. One patient reported necrosis of the mandibular incisor pulp after operation. Conclusion: Differential diagnosis of IBC is difficult, and IBC is often confused with periapical cyst. Surgical exploration and bone graft are recommended for treating IBC. Endodontic treatment of involved teeth should be evaluated before operation. Bone graft is recommended to reduce the healing period.

An aneurysmal bone cyst (ABC) can occur in many parts of the human body, but a primary ABC of the talus is extremely rare. ABCs are benign, but aggressively growing tumors that usually occur in the first two decades of life. Patients mainly complain of pain, limited movement of the involved joint or a palpable mass. Pain may worsen suddenly because of pathological fractures. If not treated properly, ABC has a risk of local recurrence, followed by the destruction of the joint and a significant functional deficit. While the complete removal of the bone tumor is essential, it is also important to treat the resultant bone defect after removal. The talus has an important part to play in weight-bearing. Therefore, an appropriate bone graft is required for large bone defects that occur after an ABC removal from the talus. We report a primary ABC of the talus in a 28-year-old male that was treated by curettage and a bone pillar pattern graft of autologous tricortical iliac crest bone. The patient had an excellent functional outcome with early weight-bearing, and there was no recurrence at 16 months of follow-up.

Multicentric chondrosarcoma other than the mesenchymal subtype is rare separate entity. We experienced a case with nonmonomelic synchronous multicentric chondrosarcoma without any preexisting lesions of Oilier's disease or Maffucci's syndrome. To our knowledge, there was no report of synchronous nonmonomelic multicentric chondrosarcoma. A thirty-three year old man had right distal thigh pain of one and half year. Bone scan showed hot lesions on medial condyle of right femur and shaft of left femur. Plain X-ray showed osteolytic lesion on right femur and slight cortical thickening and calcific lesion was observed on left femoral shaft. Curettage and bone cement filling was done on both lesions. The pathology reports were grade I chondrosarcoma on both side of femur. At one month from operation, pathologic fracture of left femur occurred on bone cement-host bone junction. Conservative treatment and radiotherapy of 60Gy was done. At 8 months from operation, nonunion was evident. Segmental resection of left femur with contralateral fibula graft and second look operation on right condyle lesion were done. At 6 months from revision, fracture occurred at host-graft bone junction. We removed previous hardware and applied long DCP and massive autogenous bone graft. Afterwards, the patient looks good and union was progressing. But at 4 years from last operation, hypertrophic nonunion occurred. Another revision was done with condylar plate and bone graft and now he is well without any sign of local recurrence or metastasis.
