Explanations & Answers:

Question Easy Answer: B
Question Easy Explanation: This patient’s clinical presentation is classic for osteoarthritis, which typically presents with joint pain that worsens with activity and improves with rest. The grating sensation, or crepitus, is characteristic as well. NICE guidelines emphasize these symptoms in osteoarthritis diagnosis.

Question Medium Answer: A
Question Medium Explanation: The symptoms suggest lumbar disc herniation at L5/S1, leading to radicular pain along the sciatic nerve path, common following heavy lifting. A positive straight leg raise test is indicative of nerve root irritation, aligning with this condition.

Question Hard Answer: A
Question Hard Explanation: The symptoms and radiological findings are indicative of ankylosing spondylitis, characterized by morning stiffness and improvement with exercise, along with sacroiliitis visible on X-ray. The pattern fits the chronic inflammatory presentation of this condition per NICE guidelines.

Medical fact of the day: Did you know that ankylosing spondylitis is more common in young men and can lead to a characteristic “bamboo spine” appearance on X-rays due to vertebral fusion?
