Answer

If both the ulnar intrinsic hand muscles and the ulnar forearm muscles are involved, then an ulnar nerve lesion in the region of the elbow (or, very rarely, above the elbow region) should be suspected. If the ulnar forearm muscles are spared, it is reasonable to consider the possibility of a lesion at the wrist, but extra caution is warranted in this case. Sometimes, the forearm muscles are spared with a lesion near the elbow, especially if the lesion is in the lower elbow region in or around the cubital tunnel.
