#1
Hwan Seong Cho, Ilkyu Han, Han-Soo Kim
There are few reports on the surgical treatment of secondary malignancy arising from an osteochondroma on the lateral side of the proximal tibia. From March 2008 to December 2011, 3 patients were treated for a secondary chondrosarcoma from an osteochondroma of the proximal tibia involving the fibula. The operative procedure can be summed up as follows: (1) resection of the tumor including the fibula; (2) preservation of the peroneal nerve and the fibular head; and (3) arthrodesis of the proximal tibiofibular joint...

Wonki Choi, Sukkyun Song, Seungbum Chae, Sangbong Ko
BACKGROUND: This study attempts to prove a cause and effect relationship between spine immobilization following posterior fixation for unstable burst fractures and degeneration observed following hardware removal. METHODS: We enrolled 57 patients (259 intervertebral discs [IVDs]) who underwent only posterior instrumentation without fusion for thoracolumbar and lumbar unstable burst fractures. We arbitrarily named the IVD that has an endplate fracture after immobilization using pedicle screws as the fractured endplate and immobilized disc (FEID), the IVD that has no endplate fracture after immobilization using pedicle screws as the nonfractured endplate and immobilized disc (NFEID), and the IVD that has no endplate fracture and no immobilization instrumentation as the normal disc (ND)...

Yuji Yasunaga, Jiro Fujii, Ryuji Tanaka, Shinji Yasuhara, Takuma Yamasaki, Nobuo Adachi, Mitsuo Ochi
Hip dysplasia is the most common cause of secondary osteoarthritis (OA). To prevent the early onset of secondary OA, Nishio's transposition osteotomy, Steel's triple osteotomy, Eppright's dial osteotomy, Wagner's spherical acetabular osteotomy, Tagawa's rotational acetabular osteotomy (RAO), and Ganz' periacetabular osteotomy (PAO) have been proposed. PAO and RAO are now commonly used in surgical treatment of symptomatic acetabular dysplasia in Europe, North America, and Asia. The aim of this paper is to present the followings: the patient selection criteria for RAO; the surgical technique of RAO; the long-term outcome of RAO; and the future perspectives...
