Prevalence of curable and pseudoarthrosis stages of adolescent lumbar spondylolysis

Abstract

Objective: The aim of this study was to determine the prevalence of curable and pseudoarthrosis stages of adolescent lumbar spondylolysis under high school students complaining of and seeking medical consultation for low back pain.Patients and Methods: We analyzed age, sex, morbidity, presence of spina bifida occulta (SBO), and competitive sport discipline of patients with lumbar spondylolysis. We then stratified their pathological stage using a modified classification system via magnetic resonance imaging and computed tomography.Results: Of 507 patients, 451 lesions in 268 patients were diagnosed with lumbar spondylolysis (average age, 14.7 years; sex ratio, 215:53 male/female). Morbidity levels were as follows: L1, 1 lesion in 1 patient; L2, 9 lesions in 5 patients; L3, 38 lesions in 25 patients; L4, 106 lesions in 74 patients; L5, 297 lesions in 189 patients, and SBO verified in 111 patients. A total of 264 patients played a specific sport: baseball, 93; soccer, 49; volleyball, 21; track and field, 21; basketball, 20; others, 164. The prevalence of curable- and pseudoarthrosis-stage lumbar spondylolysis was 206 lesions in 142 patients, and 141 lesions in 87 patients, respectively.Conclusion: With 59.3% of patients having curable-stage lumbar spondylolysis, adolescent athletes with low back pain are urged to seek consultation. Furthermore, clinicians should perform magnetic resonance imaging to avoid misdiagnosis.

Direct reduction and repair of spondylolysis with grade 1 slip using the smiley face rod: a case report

“…Repetitive hyperextension of the lumbar spine may contribute to this disorder. The treatment of acute lumbar spondylolysis should include a rest period, with bracing to allow healing, and rehabilitation, and ensure return to sports activities once patients are asymptomatic 2) . Commonly, bone fusion may not be achieved through conservative treatment that includes modification of posture, physical therapy, and bracing with a thoracolumbar and sacral orthosis.…”

Characteristics of adolescent lumbar spondylolysis with acute unilateral fatigue fracture and contralateral pseudoarthrosis

“…In some athletes, spondylolysis develops on one side only 5) . Asymmetrical movement, such as throwing and kicking, is one of the causes of this effect.…”

“…We defined SBO possession as having a neural arc cleft in either the lumbar spine or S1. Additionally, all the lesions were classified based on CT for sagittal pathological staging (stages 0, 1a, 1b, 1c, and 2) 5 ) . In the P group, we also investigated whether there was a history of low back pain that could be a symptom of contralateral spondylolysis in the past.…”

Factors Associated with Failure of Bony Union After Conservative Treatment of Acute Cases of Unilateral Lumbar Spondylolysis

“…To determine the factors signi cantly associated with failure of bony union, we conducted a univariate analysis with bony union at the nal visit as the dependent variable and the following items as independent variables: sex, age, pathological stage of spondylolysis in the axial plane of CT [9], contralateral pseudarthrosis, lesion level, and spina bi da occulta. The disease stage was classi ed as progressive or not (prelysis and early stage) and the level of pathology was separated into L5 and non-L5.…”
