Purpose: To report our experiences of clinical features, treatment method and results of giant cell tumor of 5 patients in proximal fibula. Materials and Methods: Five patients managed with an en bloc resection preserving common peroneal nerve and lateral collateral ligament reconstruction with biceps femoris tendon followed up between January 1997 and July 2001. Preoperative plain radiograph and MRI and bone scan were checked. The recurrence of the tumor was judged by plain radiograph and clinical signs. Lateral instability of knee joint was checked during the outpatient follow-up. Results: The mean age of the patients at the time of operation was twenty- three (21-29). There were one male and four female patients. Dull pain was main symptom and palpable mass was seen in two patients. Peroneal nerve palsy and local recurrence were not observed except one case of temporary peroneal nerve palsy. During the outpatient follow up, one among 5 patients showed slight lateral instability and the other 4 patients showed no instabililty. Conclusion: Giant cell tumor in proximal fibula managed with an en bloc resection preserving common peroneal nerve and lateral collateral ligament reconstruction with biceps femoris tendon showed favorable results.

The dermatoglyphic paffems of the hands and feet form during early fetal life and thereafter remain essentially unchanged. These traits are useful to study genetics and environmental factors that influence prenatal life and used in practice for personal identification and diagnosis of some diseases. The students of 112 male and 118 female were tested for the paffems of plantar regions. The most common patterns were open fields in the four interdigital areas and the frequency of the mirror pattern on them was 57.2%. For a-b, b-c and c-d ridge counts of the plantar interdigital areas sampled from 105 male and 109 female students, the nonsignificances were found between both sexes and between both feet.

The purpose of this study was to determine whether there are relationships between radiologic parameters for osteoporosis by the proximal femur radiograhps and bone mineral density, as assessed by Dual Energy X-ray Absorptiometry(DEXA). Proximal femur anterior-posterior projection were taken from 112 individuals who undergoing DEXA. Radiographic parameters including canal-to-calcar ratio(CCR) and cortical thickness indices(CTI) were measured and compared with bone mineral density($g/cm^2$), T-score. The intramedullary femoral canal width(FW) and calcar width(CW) at osteoporosis group was significantly larger than that of control group. The CCR were correlated negatively with bone mineral density($g/cm^2$)(r=-0.340, p<0.01), and the CTI were correlated positively(r=0.624). The diagnostic accuracy of CCR for osteoporosis was 63.4%, and kappa value was 0.271. And the accuracy of CTI was 67.0%, and kappa value was the level of fair agreement(${\kappa}$=0.258). The proximal femur with large CCR and small CTI had lower T-scores. When evaluating proximal femur anterior-posterior radiographs, those patients with the thinnest femur diaphyseal cortices should be referred for further osteoporosis investigation.

The leading surgical method for correcting the misalignment of the varus and valgus in the knee joint is the high tibial osteotomy (HTO). In the opening wedge HTO (OWHTO), there is no concern about damaging the peroneal nerve on the lateral tibia of the proximal fibula. OWHTO has been the preferred choice, as the opening of the correction angle can be modulated during the operation. The correction of the varus and valgus on the coronal plane are performed adroitly. Nevertheless, there have been numerous reports of unintended changes in the medial tibial plateau and posterior slope angle (PSA). The authors have developed an HTO method using computer-assisted surgery with the aim of addressing the abovementioned problems from an engineer's perspective. CT images of the high tibia were reconstructed three-dimensionally, and a virtual osteotomy was performed on a computer. In addition, this study recommends a surgical method that does not cause changes in the PSA after OWHTO. The results of the study are expected to suggest a clear relationship between the anteromedial cortex oblique angle of each patient and the PSA, and an optimal PSA selection method for individuals.

Ganglion cysts occurring within sheaths of peripheral nerves have been documented, but are relatively rare entities. The peroneal nerve at the level of the knee and proximal tibiofibular joint is most commonly involved. We report a case of the intraneural ganglion cyst in the peroneal nerve without neurologic deficit, which was excised sucessfully.

We retrospectively reviewed the cases of peroneal nerve palsy in seven patients after musculoskeletal tumor resection. Their mean age was 38 years. Three had osteosarcoma in proximal fibula, 2 had chondrosarcoma in proximal fibula and calf and 2 had malignant fibrous histio cytoma in calf. Four of 7 patients had been managed using active dorsiflexion brace. Three patients who underwent tibialis posterior transfer and could walk without brace were able to discontinue the use of the orthosis. Peroneal nerve palsy after wide excision of tumor including peroneal nerve can not resolve spontaneously and results in severe functional disability. To improve the gait function, active surgical treatment should be considered.

A giant cell tumor (GCT) of the distal radius is not common. Curettage with bone cementation is considered as a treatment of choice but, in the case of recurrence, marked cortical disruption, or articular invasion, en bloc excision and reconstruction with proximal fibular bone graft is usual procedure. In reconstruction of en bloc resected distal radius which had recurred GCT after conservative operation, we used the ultrahigh molecular weight polyethylene (UHMWPE) liner with intramedullary rod and bone cement, because the contamination was extent in previous operation and recurrence after fibular bone graft was fearful. This article introduce our new surgical procedure.
