The bifurcate coracoacromial ligament: an arthroscopic variant.
A 28-year-old woman underwent shoulder arthroscopy. Bursoscopy revealed a bifurcate appearance of the coracoacromial ligament (CAL). We believe this case report is the first description of this appearance, which represents a normal variant. Several cadaveric studies have documented a bifurcate CAL to be seen frequently at dissection. Presumably, the bifurcate segment of the CAL usually lies out of view from inspection within the subacromial bursa, thereby accounting for the rarity of the appearance we describe.
