Use of Cannulated Screws in Pelvic Injury Surgery

Abstract

Osteosynthesis with cannulated screws is one of low invasive osteosynthesis techniques that does not aggravate the condition of polytraumatized patients and can be used at the early stages of treatment. The purpose of the study was to determine the peculiarities of cannulated screws application in pelvic ring and acetabular injuries. Cannulated screws were used at surgical treatment of 368 patients, aged 14–77 years, with pelvic injuries. The overwhelming majority of patients were with severe polytrauma (17 and more points by ISS score). Pelvic ring injuries (61st segment) were diagnosed in 259 (70.4%) patients, acetabular fractures (62nd segment) — in 75 (20.4%), pelvic ring injuries associated with acetabular fractures (61st and 62nd segments) — 34 (9.2%) patients. The screws were mainly used as the basic treatment technique, rarely — in combination with internal plate osteosynthesis and more rarely — in combination with external fixation device. Analysis of the results and complications was performed. Treatment results by Majeed pelvic score at terms 1 to 3 years were studied in 207 patients. Poor results were observed in 15 (7.2%) cases. Pelvic fracture osteosynthesis with cannulated screws has a number of advantages and can be referred to as one of the basic surgical techniques for pelvic fractures.
