His lower back is tender to palpation, and he has limited range of motion. Straight leg raise test is positive on the right side, which reproduces the pain in the leg. Neurological examination of the lower extremities is normal, with no weakness or sensory deficits.
Case Questions with solutions:
⦁ What additional questions would you ask the patient to gather more information about his low back pain?
⦁ You could ask about the timing and onset of the pain, as well as anyexacerbating or relieving factors.

⦁ Thorough Musculoskeletal Exam: This exam includes palpation, range of motion, and other maneuvers that evaluate the patient's posture, alignment,and musculoskeletal structure. It is important to assess the patient's back muscles and ligaments for tenderness, swelling, or signs of inflammation.
⦁ Straight Leg Raise Test: This test involves lifting the patient's leg whilekeeping the knee straight. A positive test reproduces the patient's pain, which suggests nerve root irritation.
⦁ Neurological Assessment: The examiner should evaluate for any signs of neurological deficits, such as weakness or sensory loss in the legs. Sensoryloss may include decreased sensation to light touch, pinprick, or temperature.

⦁ What are your top three differential diagnoses for this patient's low back pain?

Low back pain can have various causes, and a differential diagnosis involves considering different possible conditions that can cause similar symptoms. The topthree differential diagnoses for this patient's low back pain are:
⦁ Lumbar disc herniation: A herniated disc occurs when the soft inner material of a spinal disc bulges out and puts pressure on surrounding nerves. The patient's positive straight leg raise test and radiating pain downthe right leg suggest that a herniated disc is a likely cause of his symptoms.
⦁ Lumbar spinal stenosis: Spinal stenosis is a narrowing of the spinal canal that can compress the spinal cord or nerves. It commonly occurs in the lumbar spine and can cause symptoms similar to those of a herniated disc.Older patient are more prone to developing spinal stenosis, and symptomsusually worsen with standing or walking.
