However, positive Tinel's sign and tenderness around the fibular neck can be keys to differentiate the root pathologies.
Subjects 4 and 5 had a Tinel's Sign over the median nerve at the wrist, Subject 4 had a Tinel's sign over the ulnar nerve at the wrist, and Subjects 4, 5, and 12 had a Tinel's sign over the ulnar nerve at the cubital tunnel.
11 (55%) patients demonstrated intrinsic atrophy, grip strength was reduced in 17 (85%) patients, and 17 (85%) patients were positive for Tinel's sign. Dellon's classification was conducted to evaluate all of the preoperative patients and 7 out of 20 patients were graded as III (severe syndrome), 11 were graded as II (moderate syndrome), and 2 were graded as I (mild syndrome) (Table 2).
Symptoms of carpal tunnel syndrome included (1) nocturnal numbness of the hand; (2) paresthesia in the distribution of the median nerve; (3) positive Tinel's sign over the carpal tunnel; (4) positive Phalen's test; (5) decreased sensibility in the distribution of median nerve; (6) decreased strength in abduction of the thumb; (7) pain intensity of at least 4 in the hand/wrist; and (8) the pain should have lasted at least 3 months.
For inclusion in the study, patients were mostly diagnosed clinically on the basis of typical signs and symptoms of CTS which are intermittent pain and paresthesia in the distribution of the median nerve in the hand usually worse at night as well as during daily activities, shaking or flicking one's hand for relieving the symptoms (Flick sign), sensory deficit in median nerve distribution of the hand, weakness of the abductor pollicis brevis muscle and atrophy of the thenar muscles, positive Phalen's test (reproducing pain and paresthesia by holding the wrist in hyperflexed position for 60 seconds) and positive Tinel's sign (tapping over the volar aspect of wrist reproduces pain and paresthesia in the distribution of median nerve) 21.
Tinel's sign was noted on examining the proximal wrist swelling.
Palpation of this area to produce what's known as a Tinel's sign (with pain and symptoms) thus should be part of the exam.
Symptoms may be reproduced by tapping over the carpal tunnel (Tinel's sign) or by full flexion of the wrist for 60 seconds (Phalen's sign).
