The Shorty Efficacy Analysis of Surgery Decompression and Direct Vertebral Remodeling Tech-niques for Lumbar Spinal Metastases

Abstract：Objective To explore the techniQue and effect of Posterior limited decompression and USS system with direct vertebral remodeling techniQues in the treatment of lumbar spinal metastases. Methods We used posterior limited decompres-sion and USS system with direct vertebral remodeling techniQues as the treatment of 21 patients,of which 14 males and 7 fe-males,who had the the diagnosis of lumbar spinal metastases between January 2009 and March 2012 in our Spine Surgery De-partment. All patients had nervous system damage and severe pain. Results The operation time was 120~180 min,the blood loss was 500~800 mL. The symptom of low back pain instantly be relieved after operation in 21 patients( 100%). After 3 months,17 cases of patient′s nerve function had been sustained improvement. Implant loosening and fracture was not found,and disease vertebral height was maintaining good,all the patient′s Quality of life was improved significantly. Conclusion Treat-ment of spinal metastatic tumors using posterior limited decompression and USS system combined direct vertebral remodeling techniQues Can instantly stabilize the vertebral. This technology can prevent vertebral paraplegia because of the pathological fractures and other complications,expand the range of application of bone cement technologies,reduces the risk of cement leak-age,while the technology can decompression effectively,relieve the severe pain,improve neurological symptoms,reduce the trauma and tumor spread opportunity and improve the Quality of life of patients. Therefore we believe this technology is an ef-fective techniQue to cure lumbar spinal metastases.
