STUDY DESIGN This is a retrospective study. PURPOSE To evaluate the effect of the dynamic rotational plate to the intervertebral foraminal and discal height after anterior cervical discectomy and fusion. OVERVIEW OF LITERATURE There is no report regarding the changes of foraminal and discal height following cervical dynamic rotational plating. METHODS We reviewed the outcomes of 30 patien...

STUDY DESIGN Radiographic evaluation of cadaveric cervical spine specimens. OBJECTIVE Assess reliability and reproducibility of foraminal dimensions obtained from cervical radiographs of varying obliquity and determine optimal angles for visualizing foramina at each cervical spine level. SUMMARY OF BACKGROUND DATA Oblique radiographs may be considered to assess cervical foraminal dimensions...

BACKGROUND Previous studies in humans have reported that the dimensions of the intervertebral foramina change significantly with movement of the spine. Cervical spondylomyelopathy (CSM) in dogs is characterized by dynamic and static compressions of the neural components, leading to variable degrees of neurologic deficits and neck pain. Studies suggest that intervertebral foraminal stenosis has ...

BACKGROUND Management approaches for adult scoliosis are primarily based on adults with idiopathic scoliosis and extrapolated to adults with degenerative scoliosis. However, the often substantially, but poorly defined, greater degenerative changes present in degenerative scoliosis impact the management of these patients. OBJECTIVE To assess the prevalence, severity, and impact of canal and fo...

OBJECTIVE We used lumbar magnetic resonance image (MRI) findings to determine possible outcome predictors of a caudal epidural steroid injection (CESI) for radicular pain caused by a herniated lumbar disc (HLD). METHODS Ninety-one patients with radicular pain whose MRI indicated a HLD were enrolled between September 2010 and July 2013. The CESIs were performed using ultrasound (US). A respond...

Objective: To compare the advantages and disadvantages of collagenase chemonucleolysis and percutaneous endoscopic discectomy (PED) in the management of extraforaminal lumbar disc herniation. Methods: In this non-randomized controlled clinical trial, a total of 49 patients who were diagnosed with extraforaminal lumbar disc herniation were assigned to undergo either PED (n=22) or collagenase che...

PURPOSE The purpose of our study was to evaluate the efficacy of direct intraforaminal steroid injections into the periganglionic space in the treatment of radicular pain. METHODS Periganglionic infiltrations were performed in 41 patients with acute or chronic radicular pain. Neuroradiologic imaging in all patients showed foraminal stenosis due to degenerative disorders or herniated disk. All...

OBJECTIVE The purpose of this study was to evaluate the outcome of endoscopic decompression surgery for intraforaminal and extraforaminal nerve root compression in the lumbar spine. METHODS The records from seventeen consecutive patients treated with endoscopic posterior decompression without fusion for intaforaminal and extraforaminal nerve root compression in the lumbar spine (7 males and 1...

OBJECT When performing surgery, the extraforaminal window is very narrow at the L5-S1 level. The authors describe a microsurgical method for decompression of the L-5 nerve root trapped between a marginal osteophyte of the vertebral body and the transverse process. The procedure was performed in 16 patients with extraforaminal stenosis. METHODS The cranial part of the L5-S1 facet joint and the...
