“…The sonographic findings correlated with the surgical findings in 82% (14 of 17). Ultrasonography showed 12 of the 14 full-thickness and two of the three partial-thickness tears but failed to show two full-thickness tears of the subscapularis tendon. In both of these false-negative cases appropriate external rotation of the arm could not be performed.…”

We studied the value of ultrasonography in identifying tears of the most anterior portion of the rotator cuff (subscapularis tendon tears). Shoulder sonography was performed on 1640 patients with shoulder symptoms, 435 of whom underwent surgery. Among the patients who were operated on, 17 had predominantly or exclusively subscapularis tendon tears; 14 of these were full-thickness and three were partialthickness tears. Ultrasonography demonstrated 82% T he rotator cuff has tendency to tear near the insertion of the supraspinatus tendon as a consequence of its lesser degree of vascularization or because of age-related changes and mechanical trauma.l Tears of the subscapularis tendon are uncommon. They are rarely found in isolation, except after severe trauma.2 Subscapularis tendon tears are found more commonly in elderly patients with recurrent shoulder dislocation or in patients with massive cuff tears) · Various clinical studies have correlated sonographic findings of rotator cuff tears to findings of open surgical procedure or arthroscopy4-7 as well as arthrographyB.9 in detecting rotator cuff tears.However, as yet, no reports have compared the sonographic findings of subscapularis tendon tears with results of surgery, arthroscopy, or arthrography. Accordingly, the aims of this study are to describe Receiwd March 13, 1995, (14 of 17) of the subscapularis tendon tears; 86% (12 of 14) of the full -thickness tears and 67% (2 of 3) of the partial-thickness tears were correctly diagnosed with ultrasonography. Sonography can diagnose and show the size of subscapularis tendon tears reliably, but it necessitates that the arm can be externally rotated to the maximum extent ~hen performing the study. KEY WORDS: Subscapulans tendon; Tears, tendon; Shoulder; Rotator cuff. the appropriate technique for the ultrasonographic evaluation of the subscapularis tendon and to discuss the reliability and restrictions of ultrasonography in the diagnosis of subscapularis tendon tears in 17 patients with surgical confirmation. PATIENTS AND METHODSFrom 1986 to 1994, 1640 patients with painful shoulder underwent bilateral shoulder sonography. Of these, 241 men and 194 women 22 to 77 years old (mean, 51 years) required surgical management. Of the 435 patients who underwent surgery, 17 had surgically confirmed tears of the subscapularis tendon. The sonographic findings in this group (11 men and six women, 34 to 58 years old; mean age, 48 years) were analyzed. The orthopedic surgeons were aware of the findings of sonography prior to surgery.All sonograms were obtained and interpreted prospectively by one radiologist (P.U.F.). The sanagrams were obtained with four different types of equipment with 7.5 MHz linear array transducers (Aloka SSD-280 LS, Aloka 650, Aloka 2000, Tokyo,

“…Contrast agent that extends over the superior aspect of the humeral tuberosities, which are normally covered by the attaching pulley ligaments, may be the only sign of a subtle pulley tear (16)-an "uncovered" humeral tuberosity. Subluxation of the biceps brachii tendon may also be intermittent, and associated injury to the supporting structures is often the only clue to possible biceps subluxation on static images (38,40).…”

The rotator interval and the long head of the biceps brachii tendon are anatomically closely associated structures believed to confer stability to the shoulder joint. Abnormalities of the rotator interval may be acquired or congenital and are associated with instability of the long head of the biceps brachii tendon. Clinical and arthroscopic diagnoses of rotator interval abnormalities and subtle instability patterns of the long head of the biceps brachii tendon are difficult. Magnetic resonance arthrography, owing to its superior depiction of ligaments with distention of the joint capsule, may be the procedure of choice, barring open surgery, for help in diagnosis of these conditions.

Ultrasonographic rotator-cuff changes in veteran tennis players: the effect of hand dominance and comparison with clinical findings

The aim of this study was to correlate sonographic abnormalities of the rotator cuff with clinical findings in veteran tennis players. One hundred fifty individuals playing competition-level tennis, aged from 35 to 77 years (mean age 55 years), underwent physical and US examinations of their shoulders. The US abnormalities found in the dominant shoulder were compared with those observed in the non-dominant shoulder and in different subsets of players defined by the absence or presence of former and/or current pain. Tears of the long head of the biceps tendon were seen only in dominant shoulders ( n=8), and tears (23 complete and 20 partial) of the supraspinatus tendon were observed in 43 dominant vs 16 (3 complete and 13 partial) contralateral shoulders ( p<0.001). Subscapularis tendon calcifications were depicted in 23 dominant vs 12 contralateral shoulders ( p<0.05). Seventy players had no pain, 49 had former-but-not-current pain, and 31 had current pain. Abnormal thickening (>2 mm) and effusion of the subacromial-subdeltoid bursa and complete tear of the supraspinatus tendon were more frequent in the latter two groups ( p<0.001 and p<0.05), respectively. Although 90% of the players with a complete supraspinatus tear had experienced former pain, no relationship was found between current pain and the presence of a supraspinatus tear or tendon calcification. The rotator cuff may present important asymptomatic lesions, such as complete tears of the supraspinatus tendon or calcifications, that do not prevent the playing competitive tennis. The only US abnormality associated with pain was subacromial-subdeltoid bursa effusion.
