To investigate the relationship of the greater tuberosity and the lateral fin of the prosthesis by using cadaveric research.
Nine pairs of fresh-frozen upper extremity specimens (n = 18) were collected. Two-part anatomical neck fracture models were created by osteotomy along the anatomical neck. A standardized humeral head replacement procedure was carried out. The prosthesis was implanted in 20 degrees and 40 degrees of retroversion respectively, and the distance between the bicipital groove and lateral fin of the prosthesis was measured.
The lateral fins of prostheses in all specimens were located behind the bicipital groove. The average distances were 7.3 mm in 20 degrees retroversion and 4.0 mm in 40 degrees retroversion.
It is better to fix the greater tuberosity over the lateral fin during humeral head replacement.
通过尸体研究探讨假体大结节与外侧鳍的关系。
收集9对新鲜冷冻的上肢标本（n = 18）。沿解剖颈截骨建立二部分解剖颈骨折模型。进行标准化的肱骨头置换手术。假体分别以20度和40度后倾植入，测量二头肌沟与假体外侧鳍之间的距离。
所有标本中假体的外侧鳍均位于二头肌沟后方。20度后倾时平均距离为7.3毫米，40度后倾时平均距离为4.0毫米。
肱骨头置换时将大结节固定在外侧鳍上方较好。
