SHORT SEGMENT TRANSPEDİCULAR SCREW APPLICATIONS İN THE TREATMENT OF LUMBAR SPINE FRACTURES
Journal Title: Journal of Turkish Spinal Surgery - Year 1997, Vol 8, Issue 1
Abstract
İn unstable spine fractures, short segment instrumentation with transpedicular screws via posterİor approach is one of the choices. İn this paper, 16 paiients, whose L1.3 burst fractures stabilised by Alıcı Splnal System, were evaluated. Mean follow-up and age of patients were 40 months (not less than 30 months) and 31.6, respectively. İn ourpatients, anterlor vertebral height (AVH) loss was 44% preoperatively, 17% postoperatively and21% in the foIlow-up. Vertebral body angle (VBA) was 23.2°, 8.5° and 11.1°, preoperatively, postoperatively and in the follow-up, respectively. Cobb angle was 7.6° preoperatively, -7,4°postoperatively and 1.2° in the follow-up. Spinai cana! encroachment in CT Scan was 46.3% preoperatively, and was 21.2% postoperatively. According to Frankel's classification only one case wİth İncomplete neurodeficit recovered partially. Wound Infectİons in 2 cases (1 superficial and 1 deep) and sterile sİnus syndrome İn 1 case were the medical complications in the postoperative period. Complications due to Instruments in the postoperative period were loosening of transpedicular screws (in 2 cases, 3 $crews), bending of transpedicular screws (İn 1 case, 2 $crews) andbreakage of transpedicular screws (in 1 case, 1 screw). As a result, aithough short segment transpedicular screw instrumentation had the advantage of short segment İmmobilİsation and sufficient anatomic reductİon we also observed screw complications especially in cases without sufficient correction.
