Common after pregnancy due to lifting the newborn
Provocative maneuver: Finkelstein test
Ulnar nerve compression at the elbow
Compression occurs in the epicondylar groove (due to direct pressure) or the cubital tunnel (due to repetitive or prolonged flexion of the elbow).
Symptoms: Paresthesias in the 4th and 5th fingers and the medial forearm, and weakness of intrinsic hand muscles.
