Abstract
Unstable posterior pelvic ring injuries remain a clinical challenge to be efficiently and promptly managed. Traumatic disruptions of the pelvic ring result in an injury of varying degree to the bony pelvis, and its soft tissue envelop. Various nerve, vessel, and visceral structures may be damaged.The aim of this study was to evaluate the results of the surgical management of unstable posterior pelvic fractures in a group of patients treated by sacro iliac screws.This work was carried out in Department of Orthopedics and Traumatology of Al-Helal Hospital. It included 20 cases with unstable post pelvic ring injuries. The age of the patient ranged from 21-63 years with a mean 37.75 years. Road traffic accidents were responsible for the majority of cases. Males were more commonly affected than females with a ratio of approximately 55%:45%.Eighteen patients were presented with unstable posterior pelvic fractures as a part of polytrauma to different body regions. The commonest associated injuries were located in the musculoskeletal system. The lower extremities were more affected than the upper extremities, femoral fractures were the commonest. Spinal fractures were present in one patient.
