A 17-year-old right hand dominant male with no past medical history comes in complaining that he broke his right finger after being tackled at football practice. You note a right hand with all fingers held in flexion except for his right index finger, which is in extension. There is some tenderness to palpation at the proximal interphalangeal joint, but otherwise normal elsewhere. He has limited flexion and extension at the second finger but otherwise normal movement in all other digits. Skin is intact with no obvious lacerations or open wounds to the hand. Sensation is intact to the median, ulnar and radial nerve distribution.

A 45-year-old man presents with right calf pain after playing basketball earlier today. As he began to run for a ball, he felt a sudden sharp pain in the back of his leg, as if he had been kicked. He can bear weight but is unable to push off with his right leg. On exam, there is swelling and tenderness on the posterior heel, but no ecchymoses or open wounds. He has full active flexion and extension in his right knee. Distal pulses are +2. Sensation is intact throughout the extremity. Ankle dorsiflexion is 4/5 and plantar flexion 0/5 on the right. Thompson test is positive. What is the diagnosis?
