Notes:
A 27-year-old woman developed a paralysis of her right hand, which affected the power of extension of her middle, ring, and little fingers, but spared the index finger and the thumb. There was a past history of injury of the elbow and dislocation of the head of the radius, and compression of the posterior interosseous nerve was suspected. After confirmation of the diagnosis by nerve conduction tests, the course of the nerve was explored surgically in the antecubital fossa. Compression seemed to be a result of two small vessels put under tension by subluxation of the head of the radius. Division of the vessels led to rapid recovery of function. The affected and unaffected muscles in this paralysis are supplied by separate branches of the posterior interosseous nerve. It seems likely that the fibers of the affected branch had been selectively compressed within the trunk of the posterior interosseous nerve. This suggests that there is sharp topographical localization of branches within the trunk of the nerve.
