Case report: Broad insertion of a large subscapularis tendon in association with congenital absence of the long head of the biceps tendon
Congenital absence of the long head of the biceps (LHB) tendon is a rare variation in shoulder anatomy. The authors present a case of congenital absence of the long head of the biceps tendon associated with a large insertion of the subscapularis muscle. The patient initially presented with shoulder pain on overhead activity. Shoulder examination was negative for signs of a torn biceps tendon. MRI revealed congenital absence of the LHB tendon, a rim rent tear of the supraspinatus, and a large insertion of the subscapularis muscle. This is the first reported case describing a large insertion of the subscapularis muscle associated with absence of the LHB tendon.5
