Abstract

Rare cases of a congenital absence of the long head of the biceps tendon (LHBT) have been reported, and its incidence is unknown. In a literature review of the congenital absence of the LHBT, only 1 case was associated with posterior shoulder instability and severe posterior glenoid dysplasia. This paper reports the first case of a patient with a bilateral congenital absence of the LHBT with posterior shoulder instability without glenoid dysplasia or posterior glenoid tilt. The patient experienced a traffic accident while holding the gear stick with his right hand. After the accident, a posteroinferior labral tear with paralabral cysts was detected on the magnetic resonance images. The congenital absence of the LHBT was assumed to have affected the posterior instability that possibly increased the susceptibility to a subsequent traumatic posterior inferior labral tear. This case was identified as a posterior inferior tear caused by a traumatic 'gear stick injury'.

Fig. 5. (A) Arthroscopic view of the inferior aspect of the glenoid with the shoulder in the beach chair position. Posteroinferior (5–9 o’clock) labral tear is noted. (B) Arthroscopic view of the posteroinferior aspect of the glenoid. The labral was repaired with a suture juggerknot 1.5 mm (Biomet, Warsaw, IN, USA).

Fig. 7. (A) Photographs of the shoulder position taken from the above when the driver pushed the gear stick reflexively in a traffic accident. (B) The drawing depicts the axial view of the transverse ligament, LHBT, humeral head at the level of bicipital groove. The transverse ligament located in front of the LHBT prevents LHBT from being dislocated in the future by pressing the LHBT, thereby preventing the posterior dislocation of the humeral head. G: glenoid, HH: humeral head, LHBT: long head of the biceps tendon, GT: greater tuberosity, LT: lesser tuberosity.
