[BIOMECHANICAL STUDY ON LOCKED RECONSTRUCTION PLATE FOR INTERNAL FIXATION OF TRANSVERSE AND POSTERIOR WALL ACETABULAR FRACTURE].
摘要
OBJECTIVE: To discuss the biomechanical stability of locked reconstruction plate for internal fixation of transverse and posterior wall acetabular fracture so as to provide a reliable basis for clinical application. METHODS: =8). Fracture was fixed with 10-hole posterior column locked reconstruction plate in the experimental group, and with 10-hole posterior column reconstruction plate combined with anterior column lag screw and posterior wall screws in the control group. Biomechanical testing machine was used for loading of 5/6 donor body mass the specimen in a speed of 15 N/s; the loading time was calculated and vertical loading.The longitudinal and quadrilateral body displacements of fracture were recorded to compare the biomechanical stability was performed. RESULTS: =0.154). CONCLUSIONS: For transverse and posterior wall acetabular fracture, application of locked reconstruction plate can provide sufficient biomechanical stability, reduce the risk of screw placement to acetabular joints.
