Patient presents with complaints of low back pain, consistent with lumbar spondylolysis.  Onset of pain is reported as gradual or acute, potentially following a specific incident of lifting, twisting, or athletic activity.  Pain is localized to the lumbar spine, possibly radiating to the buttocks or thighs, but not typically below the knees.  The patient may describe the pain as aching, stiff, or sharp, exacerbated by extension, rotation, or prolonged standing.  Physical examination reveals tenderness to palpation over the affected lumbar vertebrae.  Range of motion in the lumbar spine may be limited due to pain.  Neurological examination is typically normal, although hamstring tightness may be present.  Radiographic imaging, including lumbar X-rays in oblique views or lumbar CT scan, is ordered to confirm the diagnosis of spondylolysis and assess for the presence of a pars interarticularis defect at L4 or L5.  Differential diagnosis includes lumbar strain, lumbar disc herniation, and spondylolisthesis.  Initial treatment plan includes activity modification, rest, physical therapy focusing on core strengthening and lumbar stabilization exercises, and over-the-counter NSAIDs for pain management.  If symptoms persist despite conservative management, a referral to orthopedics or spine specialist will be considered for further evaluation and potential interventions such as bracing or epidural steroid injections.  Patient education regarding proper body mechanics and injury prevention will be provided.  Follow-up appointment scheduled in two weeks to assess response to treatment and adjust the plan as needed.
