Patient presents with complaints consistent with lumbar facet arthropathy.  Symptoms include localized low back pain, often described as aching, stiff, or sharp, exacerbated by extension, rotation, and prolonged standing or sitting.  Pain may radiate to the buttocks, groin, or posterior thigh, but typically does not extend below the knee.  The patient denies any numbness, tingling, or weakness in the lower extremities.  Physical examination reveals tenderness to palpation over the lumbar facet joints, with pain reproduced on lumbar extension and rotation.  Range of motion in the lumbar spine is limited due to pain.  Neurological examination is unremarkable.  Radiographic imaging, including lumbar x-rays, may demonstrate facet joint hypertrophy, osteophyte formation, or joint space narrowing.  Diagnosis of lumbar facet arthropathy is made based on clinical presentation, physical examination findings, and imaging studies.  Differential diagnoses include lumbar disc herniation, spinal stenosis, and sacroiliac joint dysfunction.  Treatment plan includes conservative management with nonsteroidal anti-inflammatory drugs, physical therapy focusing on core strengthening and flexibility exercises, and activity modification.  Facet joint injections or medial branch blocks may be considered for pain management if conservative measures fail.  Patient education on proper posture, body mechanics, and weight management is provided.  Follow-up is scheduled to monitor symptom improvement and adjust treatment as needed.
