A 33-year-old male patient visits his primary care physician complaining of right buttock and right leg pain with no known injury. He is employed as a long-haul truck driver and is healthy. Upon examination by a neurosurgeon, the patient exhibits normal range of motion except when raising his right leg that causes sharp pain. The surgeon orders an MRI that shows an L4-L5 herniated disc. The patient is scheduled for a lumbar discectomy.
