Vitamin D is one of important factors involved in the regulation of bone metabolism. In osteoporosis, the therapeutic effect of vitamin D on the healing process of fracture has still been controversial. These studies were designed to understand the healing process of normal fibular fracture and the therapeutic effects of $1\alpha$, 25 dihydroxycholecalciferol on the osteoporotic fracture in rats. The simple transverse fractures of rat fibulae were produced with a rotating diamond saw. The histological and ultrastructural changes of rats were observed. The histological and ultrastructural studies revealed the healing of the fibular fracture in the 5th week after simple transverse fracture. The osteoporosis impaired more the healing of osteoporotic fibular fracture than normal non-osteoporotic fibular fracture. The healing process of osteoporotic fracture was facilitated by the treatment with $1\alpha$, 25 dihydroxycholecalciferol, however, was delayed more than the healing process of normal fracture. These results suggest that $1\alpha$, 25 dihydroxycholecalciferol was effective for reducing the deleterious effects of osteoporosis in fracture healing.

Hemimandibulectomy and free fibular flap (FFF) in patients with squamous cell carcinoma could disturb the functional movement of the mandible. The muscular function in the sectioned side was compromised because of the incompetency of the muscle attachment to the mandible, leading to the unstable occlusal contact in the centric and eccentric occlusion. In this report, we present a case of a 63-year-old male who underwent cancer surgery and reconstruction with fibular graft, and he needed a fixed dental prosthesis to restore tooth loss in the anterior region. Occlusal contact change and instability were found according to the bite force in the centric relation and eccentric movement. This case report aimed to present the prosthetic procedure for fabricating the functionally optimized fixed prosthesis wherein the functionally generated path (FGP) technique and digital imaging method were applied to replicate mandibular movement and vertical dimension of the patient.

Ganglion cysts that occurred within sheaths of peripheral nerves have been documented in literatures, but it is relatively rare condition. The peroneal nerve is the most common site of involvement. Other reported sites of involvement are the radial, ulnar, median, sciatic, tibial and posterior interosseous nerves. We report a case of the intraneual ganglion cyst within peroneal nerve and another case of the intraneural ganglion cyst within a medial plantar nerve that were successfully excised without neurologic complication.

Synovial sarcomas of the hand are rare. It should be treated with wide resection. In the cases of soft tissue sarcomas of the hand, functional reconstruction must be considered. We report 46-year-old male patient with synovial sarcoma of the right thenar muscle which was treated with unplanned intralesional resection at outside hospital, that has been treated with wide resection including trapezium and first metacarapl bone then, reconstructed with nonvascularized fibular graft and anterolateral thigh free flap.

In this report, a case is presented in which resected mandible was reconstructed immediately with vascularized bone graft and adjunctive implantation of osseointegrated dental implants. The primary was central odontogenic myxoma of mandible extending from symphysis to the left condylar neck. The hemimandibulectomy defect was restored with free fibular flap. Three months after 1st surgery, the transplant received five $IMZ^{(R)}$ implants. The masticatory function was restored with the implant borne denture. The result including facial appearance was very satisfactory.

Pseudoaneurysm which is usually caused by high energy trauma or penetrating injury results in serious complications if the diagnosis is delayed. The authors experienced a 63-year-old patient who slipped on the stairs with simple contusion and skin laceration. But, he was finally diagnosed with pseudoaneurysm of tibioperoneal trunk of tibial artery on magnetic resonance imaging and 3-dimensional computed tomography angiogram performed in two weeks due to aggravation of the symptoms. To the best of my knowledge, pseudoaneurysm of tibio-peroneal trunk caused by minor blunt trauma has not been reported till now in Korea. So we report this case with a review of the relevant literature.

The radiographic findings of an osteolytic lesion in the knee may indicate numerous possible impressions. Furthermore, osteolysis is a possible cause if there is a surgical history of total knee arthroplasty (TKA). The authors diagnosed osteolysis of the fibular head after aseptic loosening of the tibial component of a cemented TKA in an 83-year-old female patient who visited with right knee pain and report their treatment with revision TKA along with a literature review.

Purpose: The purpose of this study is to evaluate the result of arthroscopic excision of painful Os subtibiale and Os subfibulare. Materials and Methods: Sixteen patients who had accessory bone in the ankle joint were treated by arthroscopy. Os subtibiale was four cases and os subfibulare twelve. The average follow-up period was 9 months$(range:6{\sim}42months)$. All patients were evaluated clinically with physical examination and radiologically with simple X-ray and for further evaluation, eight with bone scan, three with computed tomography and twelve with magnetic resonance image. We estimated the result of resection with Ogilvie-Harris's criteria. Results: All parameters of subjective and functional evaluation were improved with statistical significance(p<0.05). At final evaluation, eight patients still complained of mild pain and among them, three patients for synovitis, three for tendinitis on MRI and two for incomplete resection. Conclusion: The arthroscopic resection is a very effective method for painful os subtibiale and subfibulare using small incisions and for treatment of associated lesion. The preoperative radiological evaluation is essential and magnetic resornance image is useful for detecting of associated lesion.

The major causes of the facial bone fractures are fractures are automobile collision or other accident, and fights. Of the facial bone fractures, the nasal bone fractures are monst common. According to Schroeder et al., 50% of facial bone fractures are isolated fractures of the nasal pyramid. But the fractured nasal bone is not immediately treated as other facial bone fractures. And it is necessary to delay the treatment of the combined nasal bone fractures with other jaw bone fractures because of the difficult anesthetic techniques. Therefore there are many residual nasal deformities following a fracture; nasal hump, saddle nose and alar rim defect. Many authors have suggested the methods to correct the post-traumatic nasal deformities. We have treated several patients with several methods and this paper presents the operating methods and results.

Purpose: we would like to suggest the proper surgical methods according to the severity of instability by analyzing the results. Materials and Methods: Between January 1998 and August 2002, eighty five patients have been operated on because of posterolateral rotatory instability (PLRI). The materials were included the patients who had followed-ups for over 2 years in sixty one patients and the patient's assessments were done by clinical score (OAK, IKDC) and posterolateral drawer and dial test. Results: Through our results, the fibular tunnel turned out to be superior compared to the tibia tunnel method in rotational stability. Hughston-Jacobson methods and biceps tenodesis showed poor results. Fibula head tunnel was superior to tibia tunnel in rotational stabiliaty Conclusion: The surgical technique that passes the modified posterolateral corner sling through the fibula head tunnel may provide good clinical results in grade II PLRI. It is necessary to reconstruct both tibia and fibula tunnel in grade III PLRI. When there is combined varus instability, a positive result may be obtained if an additional LCL reconstruction is performed.
