Epidemiology, Treatment, and Performance-Based Outcomes in American Professional Baseball Players With Symptomatic Spondylolysis and Isthmic Spondylolisthesis

American Journal of Sports Medicine, 2020
Background: Repetitive lumbar hyperextension and rotation during athletic activity affect the structural integrity of the lumbar spine. While many sports have been associated with an increased risk of developing a pars defect, few previous studies have ...

Innervation of the Spondylolysis “Ligament”

Spine, 1994
Spondylolysis of the lower lumbar vertebrae is a non-united childhood fracture of the arch of the vertebra, persisting into adult life. Symptoms of disabling low back pain appear in a minority of patients, usually for the first time in adulthood. This pain is considered to arise from several separate sources, one of which may be the spondylolysis ...

Spondylolysis and Spondylolisthesis

2018
1. Spondylolysis is a defect in the pars interarticularis of the vertebra. This defect usually involves the L5 vertebra (95%) [1]. “Spondylo” derives from the Greek word for vertebra, and “lysis” refers to a defect [2] (see Fig. 148.1). 2. Spondylolisthesis is defined as a forward slip of the vertebrae relative to the one below with or ...

Pycnodysostosis associated with spondylolysis

Archives of Orthopaedic and Trauma Surgery, 2002
We report 23 years of observation of a patient with pycnodysostosis associated with progressive spondylolysis. There have been very few papers describing the development of spondylolysis associated with pycnodysostosis as confirmed by serial X-ray examinations. The diagnosis was made by the patient's typical bird-like face, plain radiological findings,

Spondylolysis and Spondylolisthesis in the Athlete

Sports Medicine and Arthroscopy Review, 2008
Spondylolysis and spondylolisthesis are common diagnoses made in the athlete suffering from persistent back pain. Although the etiology of this continuum of conditions is uncertain, genetic predisposition and repetitive trauma have been strongly implicated.

Radiographic Outcomes of Immobilization using Boston Brace for Pediatric Spondylolysis

Scandinavian Journal of Surgery, 2020
Background and Aims: Spondylolysis is a common cause of lower back pain during youth. The aim of this study is to report the bony union rate and risk factors for non-union of the lumbar spondylolysis of pediatric patients treated with a rigid ...

Spondylolysis in the adolescent athlete

Current Opinion in Pediatrics, 2011
Spondylolysis is a common cause for back pain in the adolescent athlete. Increased awareness of the presentation of this subset of patients can aid in optimal outcomes. This paper aims to review the typical presentation of spondylolysis in the adolescent with specific focus on the adolescent athlete.

Direct Repair of Spondylolysis

Clinical Orthopaedics and Related Research, 1989
Fifteen patients with spondylolysis have received compression screw and bone graft treatment for repair of this defect. In all but one case, solid fusion of the pars defect was achieved within six months after surgery. After one year, 13 of the 15 patients were able to participate fully in sports activities.

Phenotypic characterization of Slc26a2 mutant mice reveals a multifactorial etiology of spondylolysis

The FASEB Journal, 2020
Confusion persists over pathogenesis of spondylolysis. To confirm pathogenicity of the previously identified causative mutation of spondylolysis and investigate the genetic etiology, we generate a new mouse line harboring D673V mutation in the Slc26a2 ...
