Background and Aim: Degenerative lumbar scoliosis is a spinal deformity resulting from advanced disc degeneration and facet arthropathy. Given the inconclusive available literature and lack of high-quality data supporting the role of minimally invasive surgical management of degenerative lumbar scoliosis, this review intends to highlight and compare the various viable minimally invasive surgica...

background:   after cervical discectomy, autogenetic bone is packed into the cage to increase the rate of :union: between adjacent vertebral bodies, but donor site–related complications can still occur. in this study we evaluate the use   of hydroxyapatite granules as a substitute for autograft for interbody fusion.     methods:   from november 2008 to november 2011, 236 patients participated i...

Posterior lumbar interbody fusion (PLIF), as recommended with bilateral lumbar interbody cages and pedicle screw fixation, has increased the successful fusion rate to nearly 100%. Presently, a unilateral approach to the disc space with a variant of PLIF, the trans-foraminal interbody fusion is often used. There are few clinical studies of unilateral interbody fusion. The clinical and fusion res...

©2003 British Editorial Society of Bone and Joint Surgery doi:10.1302/0301-620X.85B7.13398 $2.00 e conducted a prospective, randomised study of 42 cervical interbody fusions undertaken with either an autologous tricortical graft or a cage. The factors assessed in the two groups were: (1) time taken to achieve fusion; (2) neck disability index; (3) pain score; (4) interbody height ratio; (5) int...

Degenerative disc and facet joint disease of the lumbar spine is common in the ageing population, and is one of the most frequent causes of disability. Lumbar spondylosis may result in mechanical back pain, radicular and claudicant symptoms, reduced mobility and poor quality of life. Surgical interbody fusion of degenerative levels is an effective treatment option to stabilize the painful motio...

Lumbar spinal fusions have been performed for nearly a century for a variety of spinal conditions and include posterior/posterolateral and anterior lumbar interbody fusions. Traditionally, the ability to achieve adequate exposure to perform these procedures required an open surgical approach; however, the advent of newer techniques and technology, combined with an improved understanding of surg...

Interbody fusion techniques have been promoted as an adjunct to lumbar fusion procedures in an effort to enhance fusion rates and potentially improve clinical outcome. The medical evidence continues to suggest that interbody techniques are associated with higher fusion rates compared with posterolateral lumbar fusion (PLF) in patients with degenerative spondylolisthesis who demonstrate preopera...

BACKGROUND Anterior interbody fusion has previously been demonstrated to increase neuroforaminal height in a cadaveric model using cages. No prior study has prospectively assessed the relative change in magnetic resonance imaging (MRI) demonstrated neuroforaminal dimensions at the index and supradjacent levels, after anterior interbody fusion with a corticocancellous allograft in a series of pa...

AIM To determine whether transforaminal lumbar interbody fusion aggravate adjacent segmental degeneration more adversely than anterior lumbar interbody fusion. MATERIAL AND METHODS A normal finite element model, an anterior lumbar interbody fusion model and a transforaminal lumbar interbody fusion model of L3-5 were developed. 800 N compressive loading plus 10 Nm moments simulating flexion, e...

background :the incidence of recurrence in patients undergoing primary discectomy due to lumbar disc herniation (ldh), is regularly reported as 5-15%. in this study we aimed to evaluate surgical outcome of instrumented transforaminal lumbar interbody fusion (tlif) in the patients suffering from recurrent ldh.   methods : we retrospectively studied 51 patients (30 female, 21 male) from august 20...
