The aim of the article is to investigate the efficacy and safety of 1-stage surgical therapy via combined anterior-posterior approach on cervical spine fracture in patients with ankylosing spondylitis (AS).We retrospectively analyzed profiles of 12 AS patients with severe fracture-dislocation of cervical spine received 1-stage combined anterior-posterior surgery in our hospital from October, 20...

Abstract Objective By observing the 3D anatomy of normal adult cervical facet joints, using picture archiving and communication system to measure its parameters discussing clinical significance, aim this study was provide a reliable morphological basis for design manufacture lower joint interface distractors. Methods We selected 200 patients who underwent spine spiral computed tomography (CT) e...

OBJECT The objective of this systematic review was to use evidence-based medicine to compare the efficacy of different surgical techniques for the treatment of cervical spondylotic myelopathy (CSM). METHODS The National Library of Medicine and Cochrane Database were queried using MeSH headings and keywords relevant to anterior and posterior cervical spine surgery and CSM. The guidelines group...

BACKGROUND Intermuscular approaches can expose the lumbar spine and minimize muscular trauma and injury. The segmental anatomy of the posterior lumbar musculature allows surgical access through separation of muscle groups and fascicles and provides one to develop intermuscular working channels while preserving the integrity of the muscles and their function. In addition, preservation of the acc...

We present our perioperative minimally invasive spine surgery technique using intraoperative computed tomography image-guided navigation for the treatment of various lumbar spine pathologies. We present an illustrative case of a patient undergoing minimally invasive percutaneous posterior spinal fusion assisted by the O-arm system with navigation. We discuss the literature and the advantages of...

SSEOUS BRIDGING beneath the anterior 0 spinal ligament is a feature of ankylosing spondylitis ( A S ) . When extensive this is usually associated with ankylosis of the apophyseal joints, resulting in a poker spine, or virtually complete fusion of the bony structures In 2 such cases, rupture or fracture of a calcified anterior thoracic ligament occurred following automobile accidents.l In each i...

STUDY DESIGN National population-based cohort study. OBJECTIVE To evaluate reoperation rates of cervical spine surgery for cervical degenerative conditions utilizing a national population database. SUMMARY OF BACKGROUND DATA There is an inherently low incidence of reoperation after surgery for cervical degenerative disease. Therefore, it is difficult to sufficiently power studies to detect ...

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...

Extensive mechanical loads on the lumbar spine often lead to degenerative damages of spinal structures. In many cases surgical interventions, such as spinal fusion, are unavoidable. An appropriate method for the estimation of the mechanical effects of such interventions to adjacent vertebral segments is the mathematical computer simulation. This paper presents a 3DMultiBodySimulation(MBS-) mode...
