osteotomy
Pronunciation: os-tee-OT-uh-mee
Surgical cutting of bone to correct deformity, relieve pain, or improve joint mechanics.
Full Definition
A surgical procedure involving the deliberate cutting or removal of a section of bone to correct deformities, redistribute weight-bearing forces, or improve joint alignment. Osteotomies are commonly performed around joints to treat conditions such as hip dysplasia, knee malalignment, or arthritis. The bone is typically secured with internal fixation devices after the corrective cut is made. This procedure can delay or prevent the need for joint replacement surgery in younger patients.
Usage
Usage note: Specify anatomical location and type when relevant. Distinguish from osteosynthesis (bone fixation) and osteoplasty (bone reshaping).
