Purpose: The purpose of this study was to validate the efficacy and safety of single-stage posterior debridement bone grafting for treatment of lumbar spinal tuberculosis with kyphotic deformity (LSTKD). Methods: From June 2010 to June 2013, 48 patients were enrolled in this study. Total 27 and 21 patients underwent single-stage posterior and anterior instrumentation and fusion respectively, co...

Study design: An in vitro biomechanical flexibility and fatigue test comparing two different lumbar interbody fusion cages using mono segmental lumbar spine specimens. Objective: To investigate and compare the stabilizing effect of a transforaminal lumbar interbody fusion (TLIF) cage against an expandable posterior lumbar interbody fusion (PLIF) cage. Method: Six intact human lumbar spine segme...

Spinal fusion historically has been used extensively, and, recently, the lateral transpsoas approach to the thoracic and lumbar spine has become an increasingly common method to achieve fusion. Recent literature on this approach has elucidated its advantage over more traditional anterior and posterior approaches, which include a smaller tissue dissection, potentially lower blood loss, no need f...

PURPOSE To evaluate the outcome of osteoplastic laminotomy after excision of primary tumours of the thoracolumbar and lumbar spine. METHODS Records of 10 male and 11 female consecutive patients aged 15 to 57 (mean, 37) years who underwent osteoplastic laminotomy for excision of spinal cord tumours in the thoracolumbar (n=13) and lumbar (n=8) spine were reviewed. After tumour resection, the re...

OBJECTIVE Life expectancy for humans has increased dramatically and with this there has been a considerable increase in the number of patients suffering from lumbar spine disease. Symptomatic lumbar spinal disease should be treated, even in the elderly, and surgical procedures such as fusion surgery are needed for moderate to severe lumbar spinal disease. However, various perioperative complica...

BACKGROUND Lateral approach to lumbar fusion has been gaining popularity in recent years. With increasing awareness of the significance of sagittal balance restoration in spinal surgery, it is important to investigate the potential of this relatively new approach in correcting sagittal deformities in comparison to conventional approaches. The aim of this study was to evaluate sagittal contour c...

The results of spinal fusion, especially posteriorly above the lumbosacral junction, have been mixed. Autologous growth factor concentrate (AGF) prepared by ultraconcentration of platelets contains multiple growth factors having a chemotactic and mitogenic effect on mesenchymal stem cells and osteoblasts and may play a role in initiating bone healing. The purpose of this retrospective study is ...

The aim of this study was to directly compare the clinical outcomes of posterior lumbar interbody fusion (PLIF) and minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) in three-level lumbar spinal stenosis. This retrospective study involved a total of 60 patients with three-level degenerative lumbar spinal stenosis who underwent MIS-TLIF or PLIF from January 2010 to February 20...

This study investigated the surgical outcomes of spinal surgery for degenerative disorder in patients undergoing hemodialysis. Forty patients maintained on hemodialysis who underwent spinal surgery were reviewed. Of the 17 cases of cervical surgery, anterior fusion was performed in 3 patients, laminoplasty in 12, and posterior fusion in 2. Of the 29 cases of lumber surgery, decompression surger...
