Are Constant Pain, Night Pain, or Abnormal Neurological Examination Adequate Predictors of the Presence of a Significant Pathology Associated With Pediatric Back Pain?

J Pediatr Orthop 2019 Feb 25. Epub 2019 Feb 25.

Public Health Program, Ponce Health Sciences University, Ponce.

Introduction: Previous studies have suggested that most cases of pediatric back pain do not have an identifiable cause. No reliable sign or indication differentiates between a benign or serious cause of the symptom. Constant pain, night pain, and abnormal neurological examination have been suggested as adequate predictors of an identifiable cause, when plain radiographs could not explain the symptoms. Read More

Acute rib fracture caused by preoperative positioning for direct lateral interbody fusion: A case report.

Medicine (Baltimore) 2019 Feb;98(8):e14700

Department of Orthopaedic Surgery, Soonchunhyang University Hospital Cheonan, Dongam-gu, Cheonan.

Rationale: Degenerative spondylolisthesis is defined as forward slippage of a vertebra with respect to the underlying vertebra and is associated with the induction of lumbar canal stenosis. The use of anterior column support for degenerative lumbar conditions has been well documented. Direct lateral interbody fusion (DLIF) gains access via a lateral approach through the retroperitoneal fat and psoas muscle. Read More

Posterior L5-S1 transdiscal screws for high grade spondylolisthesis - a systematic review.

Rev Assoc Med Bras (1992) 2018 Dec;64(12):1147-1153

Professor - Department of Orthopaedic Surgery, Northwestern University Feinberg School of Medicine, Chicago, IL, USA.

Objective: The surgical management of high-grade lumbar spondylolisthesis (HGLS) is complex and aims to achieve both a solid fusion that is able to support the high shear forces of the lumbosacral junction, as well as neural decompression. We performed a systematic literature review of the safety and efficacy of posterior transdiscal (PTD) screw fixation from L5S1 for HGLS and its variations.

MRI bone marrow oedema precedes lumbar bone stress injury diagnosis in junior elite cricket fast bowlers.

Br J Sports Med 2018 Nov 13. Epub 2018 Nov 13.

La Trobe Sport and Exercise Medicine Research Centre, La Trobe University, Melbourne, Victoria, Australia.

Objectives: Lumbar bone stress injury ('bone stress injury') is common in junior fast bowlers. The repetitive loading of cricket fast bowling may cause bone marrow oedema (BMO), detectable on MRI, before the bowler suffers from symptomatic bone stress injury. We investigated the temporal relationship between BMO, bone stress injury, along with bowling workload correlates, in elite junior fast bowlers throughout a cricket season. Read More

Pars interarticularis injury in elite athletes - The role of imaging in diagnosis and management.

Eur J Radiol 2018 Nov 1;108:28-42. Epub 2018 Sep 1.

Fortius Clinic, 17 Fitzhardinghe Street, London W1H 6EQ, United Kingdom. Electronic address:

Injuries of the lumbar neural arch, in particular the pars interarticularis, are widely considered to be due to abnormal bone stress secondary to repetitive loading/shearing, and are a common pathology and a main cause of lower back pain in elite athletes across a range of sports. Medical imaging plays a pivotal role in the diagnosis, monitoring and prognostication of neural arch injury. Early detection is highly desirable in the young elite athlete, as early injuries have been shown to require shorter recovery time and have a higher potential of full healing, whilst accurate grading of injury allows appropriate rehabilitation planning.

[Surgical Treatment of High-Grade High-Dysplastic Spondylolistheses in Young Patients - Prospective Monocentric Study of 29 Patients].

Acta Chir Orthop Traumatol Cech 2018 ;85(5):305-318

Klinika spondylochirurgie 1. lékařské fakulty Univerzity Karlovy a Fakultní nemocnice v Motole, Praha.

PURPOSE OF THE STUDY An optimal technique to surgically treat high-grade high-dysplastic (HG HD)spondylolistheses remains disputable. There are multiple surgical procedures described, ranging from a simple posterior fusion in situ without fixation through a standalone anterior lumbar interbody fusion with the oblique insertion of a structural bonegraft to instrumented full reduction and 360-degree fusion. At our department, preference is given to the instrumented monosegmental reduction and fixation by a fixator with Schanz screws. Read More

Multiple-Repeated Adjacent Segment Disease After Posterior Lumbar Interbody Fusion.

World Neurosurg 2019 Jan 10;121:e808-e816. Epub 2018 Oct 10.

Department of Orthopaedic Surgery, Osaka Rosai Hospital, Sakai, Japan.

Background: Although posterior lumbar interbody fusion (PLIF) has provided satisfactory clinical outcomes, adjacent segment disease (ASD) is one of the most important complications affecting long-term results. However, according to ASD studies, few have described repeat surgery. The purpose of this study was to elucidate incidence, time period, and clinical features of multiple-repeated ASD after PLIF.

Degenerative Lumbar Spondylolisthesis: Biochemical Aspects and Evaluation of Stabilization Surgery Extent in Terms of Adjacent Segment Disease Theory.

World Neurosurg 2019 Jan 29;121:e554-e565. Epub 2018 Sep 29.

Department of Pharmacology, Jessenius Faculty of Medicine, Comenius University, Martin, Slovakia.

Objective: In lumbar degenerative spondylolisthesis (DSL), the criteria and extent of surgical treatment have not been strictly defined owing to the adjacent segment disease theory and unclear molecular pathogenesis. The present study analyzed the clinical and radiographic findings of patients after lower lumbar fusion surgery with single and 2-level DSL and explored the inflammatory mediator's role in DSL evolution and symptoms.

Methods: The prospective follow-up of patients with DSL, stratified by the stabilization extent (L4-L5, L5-S1, and L4-S1), included the Back Illness Pain and Disability 9-item questionnaire and native and dynamic radiographs to evaluate the intervertebral disc height and adjacent segments' angular motion.

The Challenge of Creating Lordosis in High-Grade Dysplastic Spondylolisthesis.

Neurosurg Clin N Am 2018 Jul;29(3):375-387

High-grade dysplastic spondylolisthesis (HGDS) is a subset of L5-S1 spondylolisthesis that occurs due to dysmorphic anatomy at the lumbosacral junction, often resulting in sagittal imbalance. Enhanced understanding of global sagittal alignment has led many to preferentially treat HGDS with reduction and fusion to restore sagittal balance. The purpose of this article is to review published surgical techniques for obtaining sagittal correction in HGDS and to evaluate the current evidence regarding the associated surgical complications.

Z Orthop Unfall 2018 Dec 22;156(6):662-671. Epub 2018 Jun 22.

Unfall- und Wiederherstellungschirurgie, BG Klinikum Bergmannstrost Halle.

In a consensus process with four sessions in 2017, the working group "upper cervical spine" of the German Society for Orthopaedics and Trauma Surgery (DGOU) formulated "Therapeutic Recommendations for the Diagnosis and Treatment of Upper Cervical Fractures", taking their own experience and the current literature into consideration. The following article describes the recommendations for axis ring fractures (traumatic spondylolysis C2). About 19 to 49% of all cervical spine injuries include the axis vertebra. Read More

Biomechanical analysis of spino-pelvic postural configurations in spondylolysis subjected to various sport-related dynamic loading conditions.

Eur Spine J 2018 08 20;27(8):2044-2052. Epub 2018 Jun 20.

Department of Mechanical Engineering, Polytechnique Montreal, Montreal, QC, Canada.

Purpose: To study the risks of spondylolysis due to extrinsic loading conditions related to sports activities and intrinsic spino-pelvic postural parameters [pelvic incidence (PI) and sacral slope (SS)].

Methods: A comprehensive osseo-disco-ligamentous L4-S1 finite element model was built for three cases with spondylolysis representing three different spino-pelvic angular configurations (SS = 32°, 47°, 59° and PI = 49°, 58°, 72°, respectively). After simulating the standing posture, 16 dynamic loading conditions were computationally tested for each configuration by combining four sport-related loads (compression, sagittal and lateral bending and axial torque).
