The imaging methods reviewed included computed tomography (CT) with multiplanar reconstructions and magnetic resonance imaging (MRI). A routine part of the MRI examination included fat-suppressed T2 weighted fast-spin- or turbo-spin-echo acquisitions. As compared to the normal features in asymptomatic volunteers, alterations in the observed CT/MRI morphology and MR signal characteristics were sought in symptomatic individuals. Findings in symptomatic subjects which departed from the normal anatomic features of the posterior spinal elements in asymptomatic volunteers included: rupture of the interspinous ligament(s), neoarthrosis of the interspinous space with perispinous cyst formation, posterior spinal facet (zygapophyseal joint) arthrosis, related central spinal canal, lateral recess (subarticular zone) and neural foramen stenosis, posterior element alterations associated with various forms of spondylolisthesis, and perispinal muscle rupture/degeneration. These findings indicate that the posterior elements are major locations of degenerative spinal and perispinal disease that may accompany or even precede degenerative disc disease.

Assistant Prof. of Orthopedic Surgery. College of Medicine, University of Basrah, Basrah, Iraq. @MB,ChB, Postgraduate Arab Board Medical Specialization (Orth.) Abstract Although retrolisthesis is not a well-known condition by many medical specialists dealing with back problems and it has been regarded as a radiological incidental finding with no clinical significance, a growing prove is now evolving stating that retrolisthesis could be a cause of many backache complaints and a sequelae of an altered spine biomechanics. Objectives: to study and analyze the various biomechanical characteristics of retrolisthesis and its relationship with various radiological parameters of the lumbar spine and other patient’s factors. Patients and Method: Forty patients, twenty six males, and fourteen females with an age range from 40–66 years with radiological evidence of significant lumbar spine retrolisthesis (slip > 3 millimeters) were evaluated clinically and radiologically by plain radiography and MRI in Basra General Hospital and Ibn AL-Bittar Private Hospital, during the period from the 1st of August 2014 to the 1st of March 2015. After a thorough history and physical examination, various radiological parameters were obtained including the lumbar lordosis, sacral slop, pelvic incidence, pelvic tilt, all those measurements were done digitally. A statistical analysis was made via IBM SPSS ver.17 and the results were compared with that of similar studies.

This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. The anterior lumbar interbody fusion (ALIF) is a well-established procedure used to treat a multitude of spinal pathologies. When performed at the L5-S1 level, the ALIF is often supplemented with posterior pedicle screw and rod fixation. Because the interbody device can restore disk and foraminal height, one benefit of the ALIF procedure is indirect neural decompression in the spinal canal and neural foramina. If the contour of the posterior rod is not matched to the exact position of the tulip heads on the pedicle screws, spondylolisthesis can be introduced, leading to foraminal stenosis and nerve compression. This concern is particularly germane when the posterior instrumentation is placed percutaneously without any direct foraminal decompression. In this report, we describe a patient who had an L4-S1 ALIF, resulting in new L5-S1 retrolisthesis and worsening L5 radiculopathy.

Neurological and radiological examination showed that the spondylotic changes of the cervical spine were responsible for new neurological deficits leading to the patients being bedridden. Dystonic-athetoid neck movements may cause excessive axial neck rotation as well as flexion and extension movements of the spine. These repetitive exaggerated movements may result in early degenerative changes of the vertebrae which may enhance the radiculo-myelopathy. The four patients were treated with an anterior discectomy with interbody fusion. They were bedridden pre-operatively but all have since been able to walk with or without a cane. It is concluded that early anterior decompression with interbody fusion is a treatment of choice for cervical spondylotic radiculo-myelopathy in associa- Protected by copyright. tion with athetoid cerebral palsy.

  • Preoperative Retrolisthesis As a Risk Factor of Postdecompression Lumbar Disc Herniation
    CLINICAL ARTICLE J Neurosurg Spine 24:592–601, 2016 Preoperative retrolisthesis as a risk factor of postdecompression lumbar disc herniation Shota Takenaka, MD, Kosuke Tateishi, MD, PhD, Noboru Hosono, MD, PhD, Yoshihiro Mukai, MD, PhD, and Takeshi Fuji, MD, PhD Orthopaedic Surgery, Japan Community Healthcare Organization Osaka Hospital, Osaka, Japan OBJECT In this study, the authors aimed to identify specific risk factors for postdecompression lumbar disc herniation (PDLDH) in patients who have not undergone discectomy and/or fusion. METHODs Between 2007 and 2012, 493 patients with lumbar spinal stenosis underwent bilateral partial laminectomy without discectomy and/or fusion in a single hospital. Eighteen patients (herniation group [H group]: 15 men, 3 women; mean age 65.1 years) developed acute sciatica as a result of PDLDH within 2 years after surgery. Ninety patients who did not develop postoperative acute sciatica were selected as a control group (C group: 75 men, 15 women; mean age 65.4 years). Patients in the C group were age and sex matched with those in the H group. The patients in the groups were also matched for decompression level, number of decompression levels, and surgery date. The radiographic variables measured included percentage of slippage, intervertebral angle, range of motion, lumbar lordosis, disc height, facet angle, extent of facet removal, facet degeneration, disc degeneration, and vertebral endplate degeneration. The threshold for PDLDH risk factors was evaluated using a continuous numerical variable and receiver operating charac- teristic curve analysis. The area under the curve was used to determine the diagnostic performance, and values greater than 0.75 were considered to represent good performance.

  • Correction of Sagittal Balance with Resection of Kissing Spines
    Open Access Case Report DOI: 10.7759/cureus.16874 Correction of Sagittal Balance With Resection of Kissing Spines Eris Spirollari 1 , Eric Feldstein 1 , Christina Ng 1 , Sima Vazquez 1 , Merritt D. Kinon 1 , Chirag Gandhi 1 , Rachana Tyagi 1 1. Neurosurgery, Westchester Medical Center, Valhalla, USA Corresponding author: Rachana Tyagi, [email protected] Abstract Kissing spines syndrome, also known as Baastrup’s disease, is a common yet underdiagnosed disorder involving close approximation of adjacent spinous processes. These painful pseudoarticulations may be secondary to the compensatory mechanisms that result from sagittal imbalance. Conventional operative correction of sagittal balance includes a wide range of procedures from facetectomies to vertebral column resection. Resection of kissing spines for the operative management of sagittal imbalance is a treatment modality not extensively discussed in the literature but may offer improved patient outcomes with shorter operative times, lower risk, and reduced length of stay. A 67-year old male with a history of degenerative disk disease and scoliosis presented with neurogenic claudication and severe back pain that worsened with walking and improved with sitting. X-ray imaging of the lumbar spine revealed straightening of the normal lumbar lordotic curvature with mild rotoscoliosis. There was also evidence of retrolisthesis of L2 on L3 that worsened with flexion. The patient had Baastrup’s disease at the L3-4 and L4, 5 levels that contributed to his reduced range of motion on extension imaging. Operative treatments including long-segment fusion with interbody cages to correct sagittal balance were considered with a discussion of possible debilitating and high-risk post-surgical outcomes.
