BACKGROUND Venous thromboembolism (VTE) is a significant cause of morbidity and mortality in orthopaedic surgery. While specific guidelines exist for hip and knee arthroplasty, there is wide variation in VTE prophylaxis in complex spinal surgery. This study sought to determine the incidence of VTE, and risk factors associated with VTE, in patients undergoing elective instrumented posterior lumb...

Posterior spinal plating devices have recently made a re-emergence as both stand-alone devices and for use in conjunction with anterior fusion. Yet, the structural integrity of the posterior elements to support loads throughout the spine and the impact of plating on posterior element strength has not been well characterized. This study aims to quantify the mechanical strength of the posterior e...

STUDY DESIGN A retrospective study. PURPOSE We evaluated the results of the use of anterior debridement and interbody fusion followed by posterior spinal instrumentation. OVERVIEW OF LITERATURE An early diagnosis of pyogenic spondylitis is difficult to obtain. The disease can be treated with various surgical methods (such as anterior debridement and bone graft, anterior instrumentation, and...

BACKGROUND Interbody fusion surgery has been considered by many to be a treatment of choice for instability in lumbar degenerative disc disease. A posterior lumbar interbody fusion (PLIF) has the advantages of spinal canal decompression, anterior column reconstruction, and reduction of the sagittal slips from a single posterior approach. The PLIF using double cage was a standard practice till m...

We reviewed 40 extensive destructive vertebral lesions in 35 patients with established ankylosing spondylitis. Of these, 31 had presented with localised pain while three had a neurological deficit. The radiographs suggested ununited fractures through either ankylosed discs (37) or vertebral bodies (3). Corresponding fractures were seen in the posterior column in 34 cases. Sixteen patients with ...

there have been a number of developments in screw design and implantation techniques over recent years, including proposal of an alternative trajectory entitled as cortical bone trajectory (cbt). cortical bone trajectory has been investigated in recent medical treatments as an alternative for screw fixation aimed at increasing purchase of pedicle screws in higher density bone. cbt screw inserti...

The use of titanium cages for posterior lumbar interbody fusion (PLIF) has gained popularity because it offers the advantages of anterior column support and stabilization. However, cage migration into the spinal canal may have severe or disastrous consequences. Here, the authors report an unexpected case of posterior migration of fusion cages after screw removal in a patient that underwent PLIF...

To determine the effect of planned two-stage surgery using lateral lumbar interbody fusion (LLIF) on perioperative complication rate following corrective in patients with kyphoscoliosis. Consecutive degenerative scoliosis who underwent were divided into a control group that single-stage posterior-only and two-staged LLIF posterior fusion. We collected patient background surgical data assessed r...

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 ...

Scoliosis is common in children with cerebral palsy. The incidence and curve pattern depend on the degree of neurologic involvement. These children carry a higher risk of complications because of the increased presence of associated medical comorbidities. Accordingly, a careful preoperative evaluation is required that should involve assessment of the patient's pulmonary, nutritional, gastrointe...
