TREATMENT OF POLYFOCAL UNSTABLE DAMAGES OF THE PELVIC RING WITH OPEN BILATERAL FRACTURES WITHIN THE ANTERIOR SEMI-RING OF THE "BUTTERFLY" TYPE, WITH SYMPHYSIC DISCHARGE

Serious injuries to the musculoskeletal system include pelvic injuries with a violation of the integrity of its ring. These injuries account for 3-7% of the total number of all skeletal injuries. Various repositioning and stabilization options are used to treat unstable pelvic ring injuries. The purpose of the development is to create the possibility of a low-traumatic full-fledged out-of-focal reposition and stabilization of polypocal unstable pelvic ring injuries with open bilateral fractures within the anterior semicircle of the "butterfly" type and a divergence of the symphysis. The technology provides anatomically correct out-of-focal reposition and stabilization of displaced polypocal unstable pelvic ring injuries with open bilateral fractures within the anterior semicircle of the "butterfly" type and the divergence of the symphysis and consists in mounting the device on transosseous rods installed in the wings of the iliac bones, also spokes are counter-inserted into both pubic bones at the bases of the pubic tubercles through the symphysis into the pubic or the sciatic bone of the contralateral side through intact soft tissues. Moreover, the technology allows for a three-plane reposition of the formed single bone block of the anterior semicircle by traction and reversal with spokes and bone forceps. This reduces the duration of treatment of patients and reduces the number of infectious complications. The formation of support on the iliac bones ensures the stabilization of unstable pelvic ring injuries. Counter-inserted spokes into both pubic bones at the bases of the pubic tubercles through the symphysis into the pubic or sciatic bone of the contralateral side make it possible to reliably maintain the achieved anatomically correct relationship of the pubic bones in the restored symphysis. The developed technology makes it possible to perform a low-traumatic full-fledged out-of-focal reposition and stabilization of polypocal unstable pelvic ring injuries with open bilateral fractures within the anterior semicircle of the "butterfly" type and the divergence of the symphysis with early activation and rehabilitation of the patient, which reduces the time and improves treatment results.
