WebJun 21, 2024 · Throughout history, fractures have been treated with immobilization, traction, amputation, and internal fixation. Immobilization by casting, bracing, or splinting a joint above and below the fracture was used for most long bone fractures — except femur fractures, for which traction was the mainstay of treatment. Webstrains if any fracture site motion ( L) persists.7 Accordingly, fixation methods demand that the plates be placed on the ten-sion side of the fracture so that fracture compression is assured and excess gap motion is prevented.8 Secondary bone healing (enchondral ossification) oc-curs when relative stability is provided and strain is kept be-
