High Tibial Osteotomy

High tibial osteotomy (HTO) is a widely performed procedure to treat medial knee arthrosis. In general, published studies on HTO report good long-term results with a correct patient selection and a precise surgical technique. The ideal candidate for an HTO is a middle aged patient (60 to 65 years of age), with isolated medial osteoarthritis, with good range of motion and without ligamentous instability. Some issues that need resolution remain; these include the choice between opening and closing wedge tibial osteotomy, the graft selection in opening wedge osteotomies, the type of fixation, the comparison with unicompartmental knee arthroplasty and whether HTO significantly affects a subsequent total joint replacement. Precise indication, preoperative planning, and operative technique selection are essential to achieve good results.

A Comparative Study of Trochanteric Fractures Treated with the Intertrochanteric/subtrochanteric Fixation or the Proximal Femoral Nail

PURPOSE: To evaluate the radiographic, clinical results and the complications between who had intertrochanteric fracture, treated with the ITST or the PFN. MATERIALS AND METHODS: We selected each 30 patients of intertrochanteric fracture which were treated with ITST or PFN from July 2002 to November 2005. We evaluated the radiographic results by follow-up radiography and the clinical results with the mobility score of Parker and Palmer, Salvati and Wilson hip function scoring system and Jensen index. RESULTS: The mean distance of lag screw sliding was 4.1 mm at the ITST group and 6.6 mm at the PFN group. Decrease of mobility score of Parker and Palmer, Salvati and Wilson hip function score were similar. Patients complaint pain over lateral thigh area in 5 cases (ITST group) and 8 cases (PFN group). CONCLUSION: The ITST nail and PFN were seen good results in treatment of stable and unstable intertrochanteric fracture.

Sural Nerve Graftafter Resection of a Schwannoma in the Sciatic Nerve : A Case Report / 대한정형외과학회잡지

A schwannoma is one of the most common neoplasms in the central and peripheral nervous systems, but schwannomas of the sciatic nerve are rare. Treatment is a surgical excision and the overall prognosis is good. But functional loss occurs when a neurectomy is performed with inevitable cause. We report one case of a successful sural nerve graft after resection of a schwannoma in a sciatic nerve and we present a brief review of the literature.
