Neurilemmomas are benign tumors of the nerve sheaths. They are usually painless and are most common in the upper extremities. Pathologically, neurilemmoma is encapsulated and made up of organized element: the Antoni A cells, the Antoni B cells and the Verocay bodies. According to Stout, neurilemmomas never become malignant. Two cases of neurilemmoma of tibial nerve and One case of neurilemmoma of lateral antebrachial cutaneous nerve are presented with a review of the literature. Tumors were enucleated and confirmed by pathological examination.

Leg length discrepancy in the growing children was developed by multiple causes; such as congenital, infection, traumatic, and mechanical facotrs etc. The discrepancy have been treated by several methods including bony lengthening which is preferable method, but epiphysiodesis also has been one of the valuable methods in which was applied to the treatment of mild to moderate leg length discrepancy in the growing children. We report on patients(15 cases) with leg length discrepancy treated by percutaneous epiphysiodesis since July 1986. There were 8 males and 7 females and the average age of them was 12.6 years old. And we also performed an experimental study which was to find out the effectiveness of the pereutaneous physeal destruction comparing the techningues between curette and drill in the bony models. The causes of leg length discrepancy were trauma in 8 cases and osteomyelitis in 2 cases, congenital dislocation of the hip in 2 cases, poliomyelitis, Legg-Galve-Perthes disease, congenital hemihypertropy in each 1 case. The average preoperative leg length discrepancy was 2.6cm(range:1.9-3.7cm), and average anticipated discrepancy without operation have been 3.7cm(range:2.2-6.3cm) at maturity. The final discrepancy was 0.9cm after 43 months follow-up. According to the result by experimental study, percutaneous epiphysiodesis with curette technique would be more effective and safe than drill thchnique. Percutaneous epiphysiodesis might be one of the useful methods for the treatment of mild to moderate degree of leg length discrepancy in the growing children, and also could be applied combining with bony lengthening for treatment of severe degree of leg length discrepancy.

Agressive osteoblastoma is a very rare primary bone tumor having locally aggressive and destructive natures.But distant metastasis is not well occurred. Aggressive osteoblastoma may be similar to osteoblastomaradiologically, but has different pathological featurs. We experienced one case of aggressive osteoblastomaarising from left ilium and report this case with review of the literatures.

Diffuse tremendous thickening of gastric wall caused by excessive proliferation of the mucosa of unknown causewas first decribed by Menetrier in 1888. The disease is highly uncommon, but the exact preoperative diagnosis iscrucial because of the more excellent prognosis than other malignant lesions including gastric lymphoma andinfiltrative gastric carcinoma. The authors recently experienced a case of Menetrier's disease which had beendiagnosed as gastric lymphoma preoperatively. Radiologic differentiation is not impossible between this extermelyrare disease and other mimicking malignant lesions, that is the reason why we introduce radiographic findings ofthe case by comparison with gastric lymphoma of giant rugal type and infiltrative gastric carcinoma. Typical upperG-I series findings of the case are: 1) Enlarged tortuous proximal gastric rugal folds only along the greatercurvature, 2) Perpendicular lines of barium spicules trapped by apposed folds with clubbed or forked appearance,3) Abrupt transition of transion to normal stomach, 4) No luminal narrowing and retained but sluggish peristalsis.Thus radiologists can diagnose Menetrier's disease scrupulously based on critical application of enlarged foldspattern and extent of the lesion in association with other radiologic features and clinial history of fairly longduration. Brief review of clinical and pathologic features about Menetrier's disease is included.

PURPOSE: This study examined the displacement of the ulnar head with respect to the distal radius after distal radius malunion on the axial plane using computed tomography. MATERIALS AND METHODS: Twenty-four patients with a residual dorsal tilt > 10degrees or radial shortening > 2 mm than the normal side, and no limitation in wrist rotation after radius union were enrolled in this study. The bilateral CT scans were obtained in 70degrees pronation, neutral, 70degrees supination. The radioulnar ratio was measured and the ratios of the abnormal side were compared with those of the opposite normal side. The results were statistically analyzed using a two-tailed paired t-test. RESULTS: The ulnar head of the patients with a malunited radius had a tendency for anterior translation compared with the normal side. In patients with a dorsal tilt deformity, the anterior translation of the ulnar head with respect to the radius was significant, particularly in the supination and neutral position. However, no significant difference was found in patients with radial shortening in terms of the ulnar head translation between the normal and abnormal side. CONCLUSION: These results might explain the mechanism of distal radioulnar joint instability and low incidence of ulnocarpal impingement in patients with distal radius malunion.

PURPOSE: To analyze the clinical results of debridement arthroplasty through a medial approach for primary osteoarthritis of the elbow. MATERIALS AND METHODS: Ten patients with primary osteoarthritis treated with debridement arthroplasty trough a medial approach were investigated. The ulnar nerve was transposed anteriorly in all patients. The mean duration of follow-up was 20.8 months. The clinical results were evaluated by measuring the preoperative and postoperative range of motion (ROM) of the elbow and using Mayo Elbow Performance Score (MEPS). RESULTS: The mean flexion contracture of the elbow joint was reduced from 23 degrees preoperatively to 10 degrees, postoperatively and the mean further flexion was improved from 93 degrees preoperatively to 131 degrees postoperatively. The mean MEPS improved from 55.3 points preoperatively to 86.9 points postoperatively. CONCLUSION: Debridement arthroplasty through a medial approach is considered as an useful method for primary osteoarthritis of the elbow.

PURPOSE: The aim of this study was to establish a measurement standard for the weight-bearing axial alignment of the lower extremities when performing a lower extremity reconstruction. MATERIALS AND METHODS: Among 274 patients (147 males and 127 females) in their 20s to 30s without any physical disabilities, and who had undergone weight-bearing full leg standing radiographs, 188 patients (100 males and 88 females) were examined this study. The data was analyzed further according to their age and gender using the radiographic value on the coronal and sagittal alignment of the lower extremities. RESULTS: The weight bearing ratio was 38.47+/-10.52% on the coronal plane and 36.11+/-7.88% on the sagittal plane. Both the mechanical axis and the the weight bearing axis were not identical due to their 0.68+/-0.89degrees difference on average. The most adjacent point of the femoral condyles to the tibial plateau on the sagittal plane was assigned to the center of the knee joint. The difference between the mechanical axis and weight bearing axis was 0.04degrees, which was not significant. CONCLUSION: There is a difference between the mechanical axis, which consists of both a line from the center of the femoral head to the center of knee joint and a line from the center of the knee joint to the center of ankle joint, and the weight bearing axis, which is linked directly from the center of the femoral head to the center of the ankle joint. Furthermore, the weight bearing axis passes through the anteromedial part in the knee joint. The center of the knee joint is defined as the most adjacent point of both femoral condyle to the tibial plateau on the sagittal plane.
