One hundred four enbalmed cadaver shoulders were evaluated. With a dorsal approach we opened the dorsal capsule after resecting the infraspinatus and teres minor muscles. For reaching the anterior capsule and the glenohumeral ligaments, the humeral head was resected. In this way we could quantify and qualify the glenohumeral ligaments and classify the synovial recesses based on the classification system of DePalma into type I to VI. Secondary signs of shoulder instability were documented. The superior glenohumeral ligament was missing in 6 (5.8%) shoulders, the middle glenohumeral ligament in 16 (15.4%) shoulders, and the inferior glenohumeral ligament in 7 (6.8%) shoulders. Most of the synovial recesses belonged to group I (38.5%) and III (46.2%). As a secondary sign of instability four shoulders had a Hill-Sachs fracture and a bony Bankart lesion. All four shoulders had no middle glenohumeral ligament and a large anterior type IV recess.
对104具防腐处理的尸体肩部进行了评估。采用背侧入路，在切除冈下肌和小圆肌后打开背侧关节囊。为了暴露前方关节囊和盂肱韧带，切除了肱骨头。通过这种方式，我们可以对盂肱韧带进行量化和定性，并根据DePalma分类系统将滑膜隐窝分为I型至VI型。记录了肩部不稳定的继发性体征。6例（5.8%）肩部的肩肱上韧带缺失，16例（15.4%）肩部的肩肱中韧带缺失，7例（6.8%）肩部的肩肱下韧带缺失。大多数滑膜隐窝属于I组（38.5%）和III组（46.2%）。作为不稳定的继发性体征，4例肩部出现了Hill-Sachs骨折和骨性Bankart损伤。所有4例肩部均无肩肱中韧带，且有一个大的前方IV型隐窝。
