Abstract:
Deformities of the lower extremities can result in local complications, chronic pain and early arthritis. To correct these deformities, several techniques of osteotomies are available. In general continuous deformity correction and acute, one step procedures are available. The exact diagnostics and precise planning of the operative correction is crucial to avoid iatrogenic complications. This summary describes basic principles and indications for different types of osteotomies.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
