ABSTRACT
AIMS:
The aim of this study was to assess hypertrophy of the extra-articular tendon of the long head of biceps (LHB) in patients with a rotator cuff tear. PATIENTS ANDMETHODS:
The study involved 638 shoulders in 334 patients (175 men, 159 women, mean age 62.6 years; 25 to 81) with unilateral symptomatic rotator cuff tears. The cross-sectional area (CSA) of the LHB tendon in the bicipital groove was measured pre-operatively in both shoulders using ultrasound. There were 154 asymptomatic rotator cuff tears in the contralateral shoulder. Comparisons were made between those with a symptomatic tear, an asymptomatic tear and those with no rotator cuff tear. In the affected shoulders, the CSAs were compared in relation to the location and size of the rotator cuff tear.RESULTS:
The mean CSA was 21.0 mm2 (4 to 71) in those with a symptomatic rotator cuff tear, 19.9 mm2 (4 to 75) in those with an asymptomatic rotator cuff tear and 14.1 mm2 (5 to 43) in those with no rotator cuff tear. The mean CSA in patients with both symptomatic and asymptomatic rotator cuff tears was significantly larger than in those with no rotator cuff tear (p < 0.001). In the affected shoulders, there were significant differences between patients with more than a medium sized posterosuperior cuff tear and those with an antero-superior cuff tear.CONCLUSION:
Regardless of the symptoms, there was significant hypertrophy of the extra-articular LHB tendon in patients with a rotator cuff tear. The values were significantly related to the size of the tear. Cite this article Bone Joint J 2017;99-B806-11.Palabras clave
