Stan's Stab in the Back
Stan, a 46-year-old man, was stabbed in the back during a heated argument at a bar.
On examination 2 years later, the small muscles of his right hand were withered. His right leg was stiff and weak, and the right knee and ankle jerks were hyperactive. There was a right Babinski sign. Joint position sense was absent in the right lower extremity. On the left side, muscle strength, reflexes, and deep sensibility were normal. However, pain and temperature sense were lost over the left half of his body, from the foot up to the level of the third rib. All cutaneous sensation was absent along the ulnar side of the right arm, from the axilla to the little finger.
