BACKGROUND Currently, many scholars are concerned about the treatment of postoperative infection; however, few have completed multivariate analyses to determine factors that contribute to the risk of infection. Therefore, we conducted a multivariate analysis of a retrospectively collected database to analyze the risk factors for acute surgical site infection following lumbar surgery, including ...

BACKGROUND Less invasive fusion approaches, such as extreme lateral interbody fusion (XLIF), have proliferated, but few reports have critically assessed fusion rates. To date, no studies have reported computed tomography (CT) documented fusion rates following XLIF. METHODS An institutional review board-approved prospective radiographic and CT assessment of minimally disruptive anterior lumbar...

The incidence of symptomatic adjacent segment pathology (ASP) after fusion surgery for adult low-grade isthmic spondylolisthesis (IS) has been reported to be relatively low compared with other lumbar disease entities. However, there has been no study of symptomatic ASP incidence using posterior lumbar interbody fusion (PLIF) with pedicle screw instrumentation. We investigated the incidence of s...

introduction: alloimmunization is a reaction of the immune system to foreign antigens. for prevention of alloantibody formation, performing of type and screen test is necessary on a patient's blood specimen as part of pre-transfusion testing. materials and method: in this cross-sectional study, type and screen test done for 1420 patients with elective surgery for detection of alloantibody in im...

BACKGROUND Sacroiliac (SI) joint pain is a challenging condition to manage as it can mimic discogenic or radicular low back pain, and present as low back, hip, groin and/or buttock pain. Patients may present with a combination of lumbar spine and SI joint symptoms, further complicating the diagnosis and treatment algorithm [1-3]. SI joint pain after lumbar spinal fusion has been reported in the...

Despite X-ray and computed tomography signs of osseous stability after posterior lumbar interbody fusion (PLIF) procedures, the examination of two patients after 28 and 24 months respectively, revealed that the cages were wandering and consolidation had not taken place. Revision surgery was required in both cases. Introduction Fusion surgery in the region of the lumbar spine has become standard...

BACKGROUND Although measures to reduce and treat degenerative changes after fusion are discussed, these are still controversial. METHODS A retrospective study was conducted on a consecutive series of 3,799 patients who underwent posterior lumbar fusion for degenerative lumbar disease between January 1999 and January 2009. A total of 28 patients with symptomatic adjacent segment degeneration s...

PURPOSE To investigate the difference in motion profiles between instrumented and non-instrumented fusion of the lumbar spine. METHOD In vivo retrospective radiological analysis of dynamic (flexion-extension) lateral plain films was performed in different lumbar spine fusion types. Twenty-eight patients underwent lumbar fusion surgery at the L4/5 level. Fourteen patients underwent anterior fu...

STUDY DESIGN The radiographic and clinical results of two different anterior structural grafts were compared in 38 patients who had combined anterior-posterior revision surgery for failed lumbar fusion. OBJECTIVES Failed lumbar fusion surgery, such as pseudarthrosis or flatback deformity, may result in disabling pain. The optimum revision technique has yet to be defined. The authors of the cu...
