Relationship between the benefits of paraspinal mapping and diffusion tensor imaging and the increase of decompression levels determined by conventional magnetic resonance imaging in degenerative lumbar spinal stenosis.

J Orthop Surg Res 2019 Jan 22;14(1):23. Epub 2019 Jan 22.

Guangdong Key Laboratory of Orthopaedic Technology and Implant Materials, First Affiliated Hospital, Guangzhou Medical University, 151Yanjiang Road, 510120, Guangzhou, People's Republic of China.

Background: In lumbar spinal stenosis (LSS), at most times, several levels are impaired and selecting the correct level remains a common problem for surgeons, as surgery remains invasive, and extended laminectomy may lead to secondary surgical complications. Therefore, helping to select the correct level may be useful for surgeons. The use of diffuse tensor imaging (DTI) and paraspinal mapping (PM) in addition to conventional magnetic resonance imaging (MRI) may be helpful (Chen et al. Read More

Clinical Decision-Making in Chronic Spine Pain: Dilemma of Image-Based Diagnosis of Degenerative Spine and Generation Mechanisms for Nociceptive, Radicular, and Referred Pain.

Authors:
Haytham Eloqayli

Biomed Res Int 2018 17;2018:8793843. Epub 2018 Dec 17.

Department of Neurosurgery, Faculty of Medicine, Jordan University of Science and Technology (JUST), Irbid 22110, Jordan.

Background: Spine-related pain is a complex heterogeneous condition. Excessive reliance on radiological imaging might lead to overdiagnosis of incidental asymptomatic spinal changes and unnecessary surgery. Approaches to the clinical management of spine pain should (1) identify pain generators, types, patterns, and mechanisms; (2) confirm clinical suspension with a diagnostic injection; and (3) ensure that treatment is aimed at controlling pain and improving patient function rather than image-based surgical success.

Sagittal spinopelvic malalignment in degenerative scoliosis patients: isolated correction of symptomatic levels and clinical decision-making.

Scoliosis Spinal Disord 2018 27;13:28. Epub 2018 Dec 27.

2Department of Orthopaedic Surgery, Rush University Medical Center, 1611 W. Harrison St., Suite 300, Chicago, IL 60612 USA.

Background: This study aims to determine if (1) loss of lumbar lordosis (LL), often associated with degenerative scoliosis (DS), is structural or rather largely due to positional factors secondary to spinal stenosis; (2) only addressing the symptomatic levels with a decompression and posterolateral fusion in carefully selected patients will result in improvement of sagittal malalignment; and (3) degree of sagittal plane correction achieved with such a local fusion could be predicted by routine pre-operative imaging.

Methods: A retrospective study design with prospectively collected imaging data of a consecutive series of surgically treated DS patients who underwent decompression and instrumented fusion at only symptomatic levels was performed. Pre- and post-operative plain radiographs and pre-operative magnetic resonance imaging (MRIs) of the spinopelvic region were analyzed. Read More

Non-compressive postoperative cauda equina syndrome following decompression and transforaminal interbody fusion surgery.

BMJ Case Rep 2018 Nov 28;11(1). Epub 2018 Nov 28.

Anatomy, All India Institute of Medical Sciences, Bhubaneswar, Odisha, India.

Postoperative cauda equina syndrome (CES) is a known rare complication following lumbar disc surgery. Seldom are they seen following decompression for spinal stenosis and may be actually more frequent and under-reported? Emergent surgical exploration remains the mainstay of management as the factors responsible for postop CES remains a variety of compressive forces. Yet many a time postoperative imaging or surgical exploration fails to identify a pathology and this leads to an ischaemic theory responsible for CES. Read More

MR Imaging of the Spine: Urgent and Emergent Indications.

Semin Ultrasound CT MR 2018 Dec 19;39(6):551-569. Epub 2018 Oct 19.

Department of radiology, University of Miami Miller School of Medicine, Miami, FL.

Spinal emergencies and urgent conditions must be recognized early so that the diagnosis can be quickly confirmed and treatment can be instituted to possibly prevent permanent loss of function. The American College of Radiology provides guidelines for recognition of patients presenting with myelopathy or acute low back pain who require further evaluation for suspicion of more serious problems and contribute to appropriate imaging utilization. Spinal emergencies include spinal cord compression secondary to vertebral fracture or space occupying lesion, spinal infection or abscess, vascular or hematologic damage, severe disc herniation, and spinal stenosis.

Cervical Myelopathy Secondary to Combined Ossification of Ligamentum Flavum and Posterior Longitudinal Ligament-A Case Report.

Int J Spine Surg 2018 Apr 3;12(2):121-125. Epub 2018 Aug 3.

Department of Orthopaedics, Changi General Hospital, Singapore.

In the cervical spine, the combined ossification of the ligamentum flavum (OLF) and posterior longitudinal ligament is rarely seen. Patients are usually treated with cervical laminectomy or laminoplasty with OLF resection. In most of the cases, OLF is adhered to the dura and there is a risk of dural tear or cerebrospinal fluid (CSF) leakage during its resection. Read More

Endoscopic Transforaminal and Lateral Recess Decompression After Previous Spinal Surgery.

Int J Spine Surg 2018 Apr 3;12(2):98-111. Epub 2018 Aug 3.

Center for Advanced Spine Care of Southern Arizona, Tucson, Arizona.

Background: Leg pain and back pain after lumbar laminectomy and spinal decompression fusion surgery are common and often related to persistent lumbar foraminal or lateral recess stenosis. Although persistent symptoms often stem from incomplete decompression during the primary index surgery, recurrent symptoms may also be the result of intervertebral cage subsidence due to loss of intervertebral and neuroforaminal height.

Objective: The aim of this study was to investigate the feasibility of using the outpatient transforaminal decompression procedure as an alternative to inpatient open procedure in revision decompression surgery, with the intent of minimizing the incidence of perioperative and postoperative surgical complications while reducing both direct and indirect costs of surgical treatment, shortening time to patient postoperative narcotic independence, and shortening time of patient return to daily activities.
