[Post-traumatic medial nerve injury due to a foreign body]

A case of delayed injury to the median nerve by glass fragment is described. A median nerve palsy developed 3 years after a minor injury, totally forgotten by patient. A 34-year-old patient presented with a painful progressive median nerve lesion, with a Tinel sign just below elbow. Surgical exploration revealed a glass fragment in close proximity to median nerve. The foreign body was removed. Improvement was noted immediately, but the patient continues to have slight paresthesiae in the fingers 1 year later.
