Fibrous dysplasia is a benign disease that causes replacement of the medullary bone with fibrous tissue in one or more bones. Long bone like femur, tibia and fibular are often affected and occurring under 30 years old. We report a case of two solitary lesions of fibrous dysplasia with pathologic fracture treated with bone curettage, bone graft, plate fixation, who complains of lower leg pain.

Lateral malleolar bursitis of the ankle is a commonly encountered disease in the department of orthopedic surgery. Although most cases of lateral malleolar bursitis are managed by conservative treatments, operative treatment is considered in cases of infected bursitis or complication after surgery. There are several potential complications associated with operative treatment, including wound healing problem, skin necrosis, nerve injury, or recurrence. However, synovial fistula of the ankle as a complication after surgery for lateral malleolar bursitis has not been previously reported. The author experienced the complication of synovial fistula after surgery for lateral malleolar bursitis and obtained a satisfactory result in revision surgery for the complication, which was coverage of the fistular formation with a periosteal flap from the distal fibula.

Pigmented villonodular synovitis (PVNS) is a rare proliferative disease affecting joint synovium, tendon sheaths, bursae. The usual treatment for PVNS is a surgical excision. If destructive joint lesions have occurred, complete resections must be performed followed by arthrodesis or arthroplasty. We report a case of a pigmented villonodular synovitis involving an ankle joint which was treated by total ankle replacement for recurrence after simple synovectomy.

Flatfoot is defined as loss of medial arch with hindfoot valgus, but normal condition is obscure due to wide individual variance. Loss or decreasing of medial longitudinal arch with radiographic image is clinically diagnosed as flatfoot. Flatfoot without symptoms is not an indication for treatment. The etiologies of flatfoot are congenital cause, hypermobility, tarsal coalition, neuromuscular disease, post-traumatic deformity, Charcot arthropathy, and posterior tibial tendon dysfuction. The flatfoot is classified as congenital and acquired, flexible, and rigid. The diagnosis is made by physical examination and radiographic findings. In particular, the posterior tibial tendon dysfunction is known as adult acquired flatfoot.

Pressure distributions of the soft tissue are valuable for understanding and diagnosing the disease characteristics due to the mechanical loading. Our system measures dynamic pressure distributions in real-time under the general PC environment, and analyzes various foot disorders. Main features of the developed system are as follows: (1) With the resistive pressure sensor matrix of 40${\times}$40 cells, the data is sent to the PC with the maximum sampling rate of 40 frames/sec. (2) For each frame, contact area, pressure and force are analyzed by graphic forms. Thus, various biomechanical parameters are easily determined at specific areas of interests. (3) A certain stance phase can be chosen for the analysis from the continuous walking, and the detailed biomechanical analysis can be done according to an arbitrary line dividing anterior/posterior or medial/lateral plantar areas. (4) The center of pressure (COP) is calculated and traced from the pressure distribution data, and thus the movement of the COP is monitored in detail. A few experiments revealed that our system successfully measured the dynamic plantar distribution during normal walking.

Symmetrical Digital Gangrene (SDG) is characterized by the sudden onset of peripheral, symmetrical gangrene in the absence of any major vascular occlusive disease. Catecholamine inotropes are frequently used for the treatment of septic shock combined with an unstable hemodynamic state, and their usage can rarely induce SDG. There is no standard treatment for the SDG. Early recognition and prompt management of sepsis and expeditious process of weaning off of the inotropes are necessary to prevent progression of SDG. To the best of our knowledge, this is the first report in Korea regarding the treatment of SDG induced by catecholamine inotropes.

Myositis ossificans progressiva, otherwise called fibrodysplasia ossificans progressiva is a rare hereditary disease of unknown etiology, which is characterized by progressive ectopic ossification in connective tissues of the muscles, tendons, fascia and aponeurosis. We report a case of myositis ossificans progressiva confined to hands and feet, which has an unusual clinical feature with slow progression.

Tarsal tunnel syndrome is a complex of symptoms resulting from the compression of the posterior tibial nerve or its branches, Many disease have been previously reported in the literatures as etiological agents in tarsal tunnel syndrome. We reported a case of tarsal tunnel syndrome secondary to neurilemoma of the first branch of lateral plantar nerve. The symptoms were similar with the entrapment syndrome of the first branch of the lateral plantar nerve. Symptoms were completely relieved after operation.

Xanthoma is a relatively rare soft tissue lesion on the Achilles tendon and is usually associated with hyperlipidemia (lipid metabolism abnormality), mental retardation, cataract and atherosclerotic disease. We report on a case of normolipidemic bilateral Achilles tendon xanthoma without any notable cause. We herein describe the case where we achieved a satisfactory result by subtotal resection.

A peroneal dislocation is a rare disease that is often misdiagnosed as a simple sprain and can be treated inadequately in the acute phase. For this reason, it is important to have an appropriate diagnosis in the early stages because it can progress to chronic and recurrent conditions. Surgical treatment is considered mainly when progressing to chronic recurrent dislocation. Recently, patients with an acute peroneal dislocation tend to prefer surgical treatment, so accurate initial diagnosis and management are very important. This paper reports a case of chronic recurrent peroneal tendon dislocation in both ankle joints, which was treated by a superior peroneal retinaculum reconstruction and a groove deepening procedure.
