Intraosseus ganglion cysts are uncommon, benign, juxta-articular and usually found within long bones. A 35-year-old male presented with acute right ankle pain. He denied any traumatic event. Tenderness was localized on the subtalar joint. Radiologic studies demonstrated a cystic lesion in the juxta-articular portion of the posterior facet of the calcaneus. The patient underwent excision and curettage. Postoperative recovery was uneventful. A histological examination confirmed a typical intraosseus ganglion cyst. A case of an intraosseus ganglion cyst of the calcaneus causing acute subtalar joint pain is described.

Chondrosarcoma is one of the most common types of primary bone sarcoma. With the exception of the mesenchymal subtype, chondrosarcomas are usually low-grade lesions and rarely show multicentricity or distant metastasis. Only rare cases of multicentric chondrosarcomas have been reported in association with Ollier's disease and Maffucci's syndrome. To our knowledge, no report has been issued of a synchronous multicentric chondrosarcoma occurrence across a joint. We experienced a 30-year-old man with a synchronous monomelic juxta-articular multicentric chondrosarcoma across a shoulder joint in the absence of pulmonary and visceral metastases. He was treated by curettage and cement filling with allograft in the acromion and wedge resection with cement filling in the proximal humerus. At the 18-month follow-up, there was no evidence of recurrence, and the patient had full range of motion without pain.

Three dogs were admitted for repair of bone fracture. Case 1 (Maltese, 1.8 kg, intact female, 5-month-old) and case 2 (poodle, 3.0 kg, intact female, 6-month-old) had non-weight bearing lameness in the left pelvic limb, and case 3 (mixed, 3.3 kg, intact female, age unknown) had non-weight-bearing lameness in the left thoracic limb. On orthopedic examination, there was pain, crepitus, palpable instability and substantial soft tissue swelling on the affected side. No neurological deficits were identified. Radiographs revealed left proximal metaphyseal tibial and fibular fractures in cases 1 and 2, and left proximal metaphyseal radial and ulnar fractures in case 3. All cases had closed long-bone fractures with short juxta-articular fracture segments. Under fluoroscopic guidance, proper placement of the ring fixation elements was confirmed during surgery. Two or three rings were used to stabilize fractures with traditional circular external skeletal fixators (CESF). Postoperative radiographs showed acceptable alignment and apposition of the previously identified fracture. Time to radiographic union ranged from 5 to 14 weeks and there were no signs of implant failure or pin tract infection. Functional outcomes were excellent in all cases. CESF can be successfully used to reduce short juxta-articular fractures in which bone plates or external skeletal fixation cannot be applied.

Purpose : A cyst-like lesion within and around the knee joint is very rare, with very few articles available in the literature. The aim of this study is to evaluate effectiveness of arthroscopic treatment of cyst-like lesion within and around the knee joint which reported rarely. Materials and Methods : We are reporting 14 cases of cyst-like lesion around the knee joint. Our cases include 3 ganglion cyst in infrapatellar fat pad, 1 fibroma, 1 giant cell tumor and 1 epidermoid cyst which have not yet been reported. The diagnosis of cyst-like lesion in Juxta-articular knee Joint was made only by MRI study and we confirmed pathology. Male was 9, female was 5 cases, average age was 24(11-43)year old. Follow up was average 45(12months-8years)months. Minimum follow up was 12 months. Results : All the patients were treated arthroscopic excisional debridements successfully. All the cases were excellent result in last follow up by functional criteria in Lysholm knee score average 98.9(95-100). All examimation was normal except 3 cases in last follow up. But all patients satisfied in arthroscopic treatment. Conclusion : Arthroscopic excisional debridement of the cyst-1ike lesion in juxta-arthcular knee joint is excellent method, but long term follow up needed in the future.

The leukemias represent diffuse lesions of the bone marrow and significant bony abnormalities are associated with the more aggressive varieties of leukemias and with the younger age groups. On plain film, several roentgenographic findings are observed such as diffuse osteopenia, radiolucent metaphyseal bands, osteolytic lesions and periostitis. We evaluated bone scintigraphic findings using $^{99m}Tc-methylene$ diphosphonate $(^{99m}Tc-MDP)$ in ten patients with proven leukemia. The scan is abnormal in 90%. We classified abnormal scintigraphic findings to 3 types and these are increased diffuse juxta-articular uptake, focal increase of uptake and combined type. The common sites of focal uptake were femur, humerus, tibia, spine, ribs, calvarium, scapula and mandible. We concluded that $(^{99m}Tc-MDP)$ bone scintigraphy is sensitive imaging modality in leukemic patients with bone pain.

The management of giant cell tumor involving juxta-articular portion has always been a difficult problem. In certain some giant cell tumors with bony destruction, a wide segmental resection may be needed for preventing to recur. But a main problem is preserving of bony continuity in bony defect as well as preservation of joint function. The traditional bone grafts have high incidence in recurrence rate, delayed union, bony resorption, stress fracture despite long immobilization and stiffness of adjuscent joint. We have attemped to overcome these problems by using a microvascular technique to transfer the fibula with peroneal vascular pedicle as a living bone graft. From Apr. 1984 to Nov. 1990, we performed the reconstruction of wide bone defect after segmental resection of giant cell tumor in 4 cases, using Vascularized Fibular Graft, which occur at the distal radius in 3 cases and at the proximal tibia in 1 case. An average follow-up was 2 years 8 months, average bone defect after wide segmental resection of lesion was 11.4cm. These all cases revealed good bony union in average 6.5months, and we got the wide range of motion of adjacent joint without recurrence and serious complications.

Treatment of giant cell tumor of distal radius can be treated in several ways according to the aggressiveness of the tumor. But the management of giant cell tumor involving juxta-articular portion has always been a difficult problem. In some giant cell tumors with bony destruction, a wide segmental resection may be needed for preventing to recur. But a main problem is preserving of bony continuity in bony defect as well as preservation of joint function. We have attempted to overcome these problems by using a microvascular technique to transfer the fibula with peroneal vascular pedicle or anterior tibial vessel as living bone graft. From April 1984 to July 2005, we performed the reconstruction of wide bone defect after segmental resection of giant cell tumor in 14 cases, using Vascularized Fibular Graft, which occur at the distal radius. VFG with peroneal vascular pedicle was in 8 cases and anterior tibial vessel was 6 cases. Recipient artery was radial artery in all cases. Method of connection was end to end anastomosis in 11 cases, and end to side in 3 cases. An average follow-up was 6 years 6 months, average bone defect after wide segmental resection of lesion was 6.8 cm. All cases revealed good bony union in average 6.5 months, and we got the wide range of motion of wrist joint without recurrence and serious complications. Grafted bone was all alive. In functional analysis, there was good in 7 cases, fair in 4 cases and bad in 1 case. Pain was decreased in all cases but there was nearly normal joint in only 4 cases. Vascularized fibular graft around wrist joint provided good functional restoration without local recurrence.
