Spondylolysis, Lumbar, L5

ICD-10 Code
M43.07

Defect or stress fracture in the pars interarticularis of the L5 vertebra.

Clinical Presentation & Protocol

Patient Usually Complains Of

Patient presents with localized lower lumbar pain, exacerbated by lumbar extension and rotational activities. Pain is mechanical in nature, non-radicular, and often associated with athletic activity. No bowel/bladder dysfunction or saddle anesthesia reported.

Clinical Examination Findings

Lumbar spine examination reveals localized tenderness over the L5 spinous process. Pain is reproduced with single-leg hyperextension (Stork test) on the affected side. Neurological exam is intact with 5/5 strength in lower extremities, symmetric reflexes, and negative straight leg raise.

Treatment Protocol

Conservative management initiated: activity modification to avoid hyperextension, physical therapy focusing on core stabilization and pelvic tilt exercises, and NSAIDs for pain control. Consider bracing if symptoms persist or for acute stress reaction management.
