Biomechanical feature measurement of Swan-like memory compression connector
摘要
Abstract
BACKGROUND: The biomechanical features of Swan-like memory compression connector designed for fractures in hemerus or the parts adjacent to joints are analyzed through biomechanical calculation and experimental measurements.OBJECTIVE: To analyze the relative memory biomechanieal significance through biomechanical measurement of Swan-like memory compression connectorDESIGN: Both biomechanieal calculation and the experimental measurement were conducted for mutual supplementation and confirmation SETTING: The Orthopaedic Department of Changhai Hospital Affiliated to Second Military Medical University of Chinese PLA and the Life Science and Tissue Engineering Institute of Tongji University MATERIALS: This experiment was conducted at the laboratory of Orthopaedic Department of Changhai Hospital Affiliated to Second Military Medical University of Chinese PLA and the Life Science and Tissue Engineering Institute of Tongji University between January 2001 and May 2003.Totally 20 hemerus from adult males who died of craniocerebral injury were chosen.METHODS: Humid hemerus from the adult corpse was chosen to prepare fracture. Encircling the prescale followed by fixation of Swan-like memory compression connector, then we measured the stress produced by compression part and encircle part at fixing the fracture.MAIN OUTCOME MEASURES: ①The stress of holding part; ② the stress of the compression part RESULTS: The stress range of holding part contacting with humerus was 2.42-22.68 N, and the stress in the fracture face, which was produced by compression part, was about 13.6 Mpa.CONCLUSION: The stress of holding part of Swan-like memory compression connector is useful in fixing the fracture parts of humerus, and the stress of compression part is suitable for the healing of fracture.关键词
