  • Sacral schwannoma is a rare lesion with a tendency to reach large proportions. The benign schwannoma rarely involves the vertebral bodies extensively. The authors report a case of giant intrasacral schwannoma in 30-year-old woman who had intermittent lower back pain during 3 years period. CT and MRI showed a destructive mass lesion within the upper part of sacrum with a large mass extending into the presacral space. The patient underwent combined surgery consisted of anterior transabdominal approach and posterior sacral laminectomy and total removal of tumor. The characteristics of the lesion were discussed with a review of literatures.

  • Schwannomas are uncommon neoplasms arising from Schwann cells of the neural sheath. Gastrointestinal schwannomas are rare, accounting for 1% of all malignant gastrointestinal tumors. Colonoscopic biopsy with immunohistochemical (IHC) staining is useful for confirming this tumor. We report on a patient with schwannoma arising from the ascending colon, which was detected by colonoscopy and endoscopic submucosal dissection was attempted. A 41-year-old man presented with abdominal discomfort. The patient was diagnosed with a subepithelial tumor on colonoscopy. He underwent endoscopic submucosal dissection. Histopathology and IHC staining confirmed that the colonic lesion was a benign schwannoma. However, the resection margin was positive. Therefore, laparoscopic ileocolectomy was performed.

  • Traumatic dislocation of the peroneal tendon is a rare injury. It should be distinguished from other conditions that can cause pain and disability of lateral aspect of the ankle joint. We experienced a case of chronic recurrent dislocation of the peroneal tendon, which was treated by deepening of the peroneal groove of the lateral malleolus and reattachment of the superior peroneal retinaculum. The clinical result was satisfactory.

  • The fracture and fracture-dislocation of the neck of the talus (Hawkins' type I-IV) are uncommon injuries and represent only 0.12 to 0.32% of all fracures. Authors clinically evaluated in 12 cases Whom treated fracures of the neck of the talus, at department of orthopaedic surgery, Sun General Hospital, from 1990 to 1996, and the following results are obtained. 1. Of 12 cases, there were 11 males and 1 female, average age was 30 years. 2. Causes of fracture was fall down injury in 7 cases(58%), traffic accident in 4 cases(33%), direct trauma in 1 case(8%). 3. According to the classification by Hawkins' type I in 2 cases(17%), type II in 7cases (58%), type III in 3cases(25%). 4. Associated injuries were calcaneal fracture in 3 cases, fracture-dislocation of talus in 3 cases, subtalar dislocation in 3 cases, medial malleolar fracture in 5 cases, soft tissue injury in 3 cases, femur and tibia fracture in 1 case, and lumbar Spine compression fracture in 1 case. 5. Average time to operation after injury was 2.5 days. 6. In 2 cases were treated conservatively and 10 cases were treated open reduction and internal fixation with screw or K-wire. 7. Complications were avascular necrosis in 4 cases, post traumatic arthritis in 2 cases, skin necrosis in 4 cases, and then ankle fusion was done in 2 cases. 8. High rate of complication was seen in the talar neck fracture associated with calcaneal fracture. In the analysis of above results, evaluated by Hawkins' scoring system were excellent to fair in 75%.

  • Pigmented villonodular synovitis (PVNS) is a slowly, progressive, proliferative disorder of synovial tissue characterized by villous or nodular changes of synovial-lined joints, bursae, and tendon sheaths and most frequently affects the large joints, with the knee and hip. A few studies have been reported that occurred PVNS in small joint, but mainly in hands. It is a very rare condition that occurs in the small joints of the forefoot. We have experienced the case, which developed in small joint of the forefoot, and performed total synovectomy. After the operation, there was no recurrence. We report a case of PVNS in forefoot with a review of the literature.

  • Inappropriate treatment of osteochondral fracture can cause osteoarthritis, pain, functional disorder. With large osteochondral fracture, reduction and fixation of the fragment using metal implant. However, when the bone fragment had less than 2mm, the fragment extracted because of difficulty of fragment fixation. Authors treated patients with fracture fragment thickness less than 2mm of osteochondral dissecans in medial femoral condyle and patella fracture using biodegradable meniscus screw, and then we obtained good result.

  • Ganglion cysts have been described in all joints. In the knee, although the finding of meniscal degenerative cysts is fairly common, a few cases have been reported concerning ganglion cysts of anterior cruciate ligament. However, ganglion cysts of posterior cruciate ligament are quite rare. We experienced two cases of ganglion cyst in the posterior cruciate ligament, which were treated successfully with arthroscopic debridement.
