为了更好地定义肱骨下关节囊解剖结构，解剖了12个尸体肩关节，并进行了下关节囊移位。确定了两种类型的肱骨下附件。在7个标本中，前囊附着点在8点钟位置（右侧标本）分叉为邻近关节软骨的上级内折和肱骨外科颈上的下外折。在5个样本中，囊插入没有分裂，但插入在手术颈部的广泛区域。在所有标本中，在4点钟位置的两个褶皱重新汇合。肱骨下关节囊附着可延伸至关节面下方2 cm，并可分为两种不同类型，分裂型和宽型，每种类型都有不同的关节囊内外折叠。未能释放这两个折叠限制了通过将囊向内侧栓系而向上移动囊的能力。
To define inferior humeral capsular anatomy better, 12 cadaveric shoulders were dissected and an inferior capsular shift was performed. Two types of inferior humeral attachments were identified. In 7 specimens, the anterior capsular insertion bifurcated at the 8-o’clock position (on a right specimen) into a superior internal fold adjacent to the articular cartilage and an inferior external fold on the humeral surgical neck. In 5 specimens, the capsular insertion did not split but inserted over a broad area on the surgical neck. In all specimens, there was a re-confluence of the two folds at the 4-o’clock position. The inferior humeral capsular attachment may extend as far as 2 cm inferior to the articular surface and can be divided into two distinct types, split and broad, each with distinct internal and external folds of the capsule. Failure to release both of these folds limits the ability to shift the capsule superiorly by tethering the capsule inferiorly.
