Background: We reported that transverse cervical artery had various forms in the cadaver. The purpose of this study was to examine patients with neck and shoulder pain from vascular resistance of the transverse cervical artery.Methods: The subjects consisted of 54 patients with neck and shoulder pain (group P) and 20 normal volunteers (group N). They were all females, and their mean age was 67.2 in group P and 70.4 in group N.Firstly isometric exercise around the neck and back was performed on all subjects in the sitting position. Patients were only asked whether the pain had changed before and after exercise. The transverse cervical artery was identified by color doppler ultrasonography, and pulsatility index (PI) was measured by pulsed doppler imaging. PI was compared between group P and group N, and was compared with the effects of exercise in group P.Results: After exercise, the pain was the same in 16 patients, improved partially in 27 patients and disappeared in 11 patients. PI of the deep branch in the group P was significantly larger than that in group N. PI of the deep branch in the 11 patients whose pain disappeared, tended to be smaller than that of the other patients.Conclusion: We suppose that high vascular resistance of the deep branch of the transverse cervical artery is a characteristic seen widely in patients with neck and shoulder pain.

(Purpose) Voluntary dislocation of the tendon of the long head of the biceps is extremely rare. Here we will report on this dislocation in one patient.<br>(Patient) The Patient, a 37-year-old male fell down with his arm extended. Since then, he had a click and pain of the shoulder when he elevated his arm. When he had contracted his biceps with his arm extended and internally rotated, the tendon of the long head of the biceps dislocated from the bicipital groove. By elevating the arm 135 degrees from that position, the tendon reposited with a click and pain. Arthrography showed a dislocation of the tendon of the long head of the biceps. Arthroscopy and a tenodesis of the biceps tendon were performed.<br>(Conclusion) When observing the shoulder joint of a cadaver, the insertion of the subscapularis tendon was separated into two layers. One was a superficial layer, the other a deep one. Some parts of the superficial layer formed the transverse ligament. So we believe that the tendon of the long head of the biceps is often dislocated accompanying with a tear of the subscapularis tendon.

We performed a comparative study on shoulder injuries between snowboards and skis.<BR>1665 patients injured by snowboarding or skiing visited our hospital from 1997 to 1999 (males: 1173, females: 492, averagc age: 25.3). There were 883 patients injured by snowboarding (males: 667, females: 216, average age: 23.6) and 782 patients injured by skiing (males: 506, females: 276, average age: 27.3).<BR>There were 523 patients (59.2%) with upper extremity injuries caused by snowboarding. Among them there were 191 patients (21.6%) with shoulder injuries. There were 62 fractures (clavicle: 40, proximal end of the humerus: 22),78 dislocations (acromioclavicular joint: 32, shoulder joint: 46) and 1 dislocation fracture (shoulder joint). There were 235 patients (30.1%) with upper extremities injured by skiing. Among them there were 133 patients (17.0%) with shoulder injuries. There were 53 fractures (clavicle: 36, proximal end of the humerus: 14, scapula: 3),41 dislocations (acromioclavicular joint: 10, shoulder joint: 31) and 6 dislocation fractures (shoulder joints).<BR>Snowboarders fall on their hands frequently. Therefore upper extremity injuries and shoulder injuries caused by snowboarding are considered to be more than by skiing.
