ABSTRACT
Objective To explore the effect of posterior column stability and decompression on the treatment of lumbar burst fracture with nerve injury and its effect on vertebral body and neurological function.Methods Fifty-two cases patients of lumbar burst fracture with nerve injury from February 2005 to July 2014 in Affiliated Hospital of Youjiang Medical College For Nationalities were selected as the research objects and divided into retention group(28 cases) and non-retention group(24 cases) according to the choice of operation method.The surgical clinical efficacy,the changes of the vertebral body and nerve function were compared between two groups.Results At 3 months,6 months and 12 months after operation,the fusion rate,sagittal diameter and the height of the injured vertebral body,pre-vertebral body,and intervertebral space were all significantly increased,while the Cobb angle,the pressure area and the sagittal displacement rate were markedly decreased(F of inner grouP=10.492,8.858,7.432,16.311,19.491,10.329,21.587;P0.05).After operation,the ASIA grade gradually improved,neurological function of the retention group recovered at 6 months after surgery,while non-retention group presented this effect at 12 months after surgery,moreover,at 12 months after operation,the proportion of E grade in retention group was 64.29%,higher than that of non-retention group(45.83%,F=12.758,P<0.001).The levels of neuron-specific enolase(NSE),S100B protein and myelin basic protein(MBP) in retention group were significantly lower than those of the non-retention group at 3 months after surgery(P<0.05).The improvement of S100B and MBP in the reservation group at 6 months after surgery were better than those of non-retention group,while at 12 months after surgery,only the improvement of MBP in retention group showed the better effects than non-retention group.Conclusion Posterior column stability and decompression show a high clinical efficacy on the treatment of lumbar burst fracture with nerve injury and it can significantly improve the vertebral body and neurological function.
ABSTRACT
Objective To introduce the clinical application of the improved interosseous dorsal antidromic artery issular flap in the emergency treatment of the soft tissue defects in hand trauma. Methods 16 patients were received the interosseous dorsal antidromic artery flap for soft tissue defects in the hand with emergency treatment. Results All 14 flaps survived, tip necrosis occurred in 2 cases which healed without complications. Conclusion It was simple technical and shorten time in hospital with improvement of the emergency operative procedure of interosseous dorsal antidromic artery flap, and could reduce the impact of frequency of anatomic variations and vascular complications.
