Objective:
To determine whether there is an association between hamstring injury diagnosis and clinical lumbar spine pathology.
Design:
Retrospective analysis of a matched cohort of patients with and without a diagnosis of hamstring injury.
Setting:
Cone Health System-affiliated clinics, urgent cares, and emergency departments.
Patients:
In total, 1269 patients identified in EPIC records with a diagnosis of hamstring injury; a control group of 1269 demographically matched patients who did not have a diagnosis of hamstring injury.
Interventions:
Chart review of patients to assess for lumbar spine pathology in those with and without prior hamstring injury.
Outcome Measures:
Odds ratio (OR) of having lumbar spine pathology in the hamstring injury group and the control group. OR of having lumbar spine pathology based on other demographics.
Results:
Patients with a diagnosis of hamstring injury had an OR of 1.84 for having lumbar spine pathology. Of other variables, only BMI > 30 had a positive OR of 1.35. Likelihood of lumbar spine pathology does increase steadily in all age groups.
Conclusions:
Patients with a history of hamstring injury are 84% more likely to have lumbar spine pathology than a matched cohort without a history of injury. Hamstring injury was a stronger predictor of lumbar spine pathology than BMI, age, or other variables.
