Problems of bridging plate fixation for the treatment of forearm shaft fractures with the locking compression plate.

Introduction: Treatment of diaphyseal forearm fractures by open reduction and internal plate fixation is a well-accepted strategy. In a variety of fracture localizations, the use of bridging plate fixation with locking compression plates (LCP) has been shown to improve biomechanical and biological characteristics. Only very limited clinical data are available on bridging plate fixation using LCPs for the treatment of diaphyseal forearm fractures.

Bone debris: dead matter or vital osteoblasts.

Background: Mechanical manipulation, pressure, and temperature increase can induce bone necrosis during intramedullary reaming.

Methods: In this study, the bone debris obtained after reaming 18 sheep tibiae was analyzed to investigate its vitality by measuring alkaline phosphatase activity. Two different reamer designs were used for the project.
