osteosynthesis
Pronunciation: os-tee-oh-SIN-the-sis
Surgical fixation of bone fractures using internal devices to promote healing.
Full Definition
Osteosynthesis refers to the surgical technique of fracture fixation using internal devices such as plates, screws, nails, or wires to hold bone fragments in proper alignment during healing. The term literally means 'bone putting together' and encompasses various methods of internal fixation. The goal is to provide sufficient stability to allow bone healing while maintaining or restoring normal anatomy. Osteosynthesis enables early mobilization and functional rehabilitation compared to external immobilization methods. The choice of implant and technique depends on fracture pattern, bone quality, patient factors, and surgeon preference.
Usage
Usage note: More formal term than 'internal fixation' but both are acceptable.
