Macrodystrophia lipomatosa is a congenital disease characterized by gradual proliferation in the mesenchymal cell, such as fibroadipose tissue. Pathologically, fatty tissue is deposited in the nerve sheath, periosteum, bone marrow, and subcutaneous tissue, contributing to the macrodactyly of the foot. To date, there has not been any report on macrodystrophia lipomatosa of the superficial peroneal nerve in the Korean orthopedic literature. Conservative approach, such as decompression or debulking surgery, is recommended due to neurogenic dysfunction. However, we report a 43-year-old male with macrodystrophia lipomatosa involving the superficial peroneal nerve of the right foot and ankle, who underwent a second toe ray amputation as well as soft tissue and nerve resection.

Kienbock's disease is very rare in pediatrics. The treatment of Kienbock's disease is controversial and depends on an understanding of the natural history of the disease. The methods proposed vary from conservative treatment to surgical treatment such as radial shortening or scaphotrapezoidal joint fixation, but there are few therapeutic guidelines for paediatric Kienbock's disease. We encountered a 14-year-old male with Lichtman stage IIIB disease and treated him with conservative management. We report this rare case of advanced paediatric Kienbock's disease with good clinical results at the 2-year follow-up along with a review of the relevant literature.

Acute bone shortening and delayed lengthening by Ilizarov surgery have been used to treat a wide range of soft tissue injuries including open fracture, osteomyelitis of the tibia and lower leg amputation. It has advantages such as bone lengthening as well as minimizing the loss of damaged tissues via tissue expansion. Here, we report a case of 52-year-old male with satisfactory results through acute bone shortening, replantation, and gradual bone lengthening after complete amputation of the ankle with related literature reviews.
