STUDY DESIGN  Retrospective case series. Evidence level IV. OBJECTIVES  To evaluate surgical candidates with foraminal or extraforaminal lumbar disc herniation treated with CT-guided periradicular injection (CTGPI) as a valid treatment option for avoiding surgery. METHODS  We carried out a retrospective evaluation of 46 consecutive patients with foraminal or extraforaminal disc herniation t...

Brachial plexus lesions most often occur in multiple trauma. We report a case of 37-year-old patient who presented an upper left limb total sensitivomotor deficit and amyotrophy after cervical Cervical magnetic resonance imaging (MRI) was performed. It noted pseudomeningoceles at the levels C6-C7, C7-D1, D1-D2 T1 hyposignal , T2 STIR hypersignal not enhanced by injection Gadolinium extending fo...

STUDY DESIGN Retrospective observational study. PURPOSE To examine fractional anisotropy (FA) values and apparent diffusion coefficient (ADC) values of damaged nerves to discriminate between lumbar intraspinal stenosis (IS) and foraminal stenosis (FS) using diffusion tensor imaging (DTI). OVERVIEW OF LITERATURE It is important in the selection of surgical procedure to discriminate between l...

OBJECTIVE To suggest a new useful diagnostic technique, principles of the selective excitation technique-magnetic resonance images (Proset-MRI), and to know the precise radiologic findings that can prove symptomatic foraminal and extraforaminal stenosis at L5-S1. METHODS Nineteen patients with symptomatic L5-S1 stenosis were checked by Proset-MRI. Four patients were performed decompressive su...

BACKGROUND Although several authors have reported the use of endoscopic techniques to treat lumbar foraminal stenosis, the practical application of these techniques has been limited to soft disc herniation. OBJECTIVE To describe the details of the percutaneous endoscopic lumbar foraminotomy (ELF) technique for bony foraminal stenosis and to demonstrate the clinical outcomes. METHODS Two yea...

Objective: Extraforaminal juxtafacet cyst is rare and present a surgical challenge due to its anatomical location. This study aimed introduce the technique of interlaminar contralateral endoscopic lumbar foraminotomy (ICELF) for extraforaminal removal reveal approach-related benefits.Method: The endoscope was docked on ipsilateral spinolaminar junction access foraminal area through sublaminar s...

The extent of the slice thickness in spinal axial and sagittal magnetic resonance imaging (MRI) is limited. We therefore, propose the idea of using coronal MRI to better delineate lumbar far lateral disc herniations. Six patients with coronal MR images who underwent surgery are presented in this study. Simple 2D vertebral column X-ray and MRI scans were used to diagnose the far lateral herniate...

The lateral lumbar spinal canal may be subdivided into the subsequently necessitate fusion surgery. Other, more lateral approaches subarticular (lateral recess), the foraminal (pedicle) and the extraforaminal (far lateral) zone. Within these regions lies the “hidden zone”, an area known for its difficult surgical exposure (Fig. 1A) (Macnab, 1971). Common pathologies of this region include foram...
