目的:为修复肱骨近端提供新的手术方法。方法:在40例成人尸体标本上,观察了胸肩峰动脉走行、分支及分布。结果:胸肩峰动脉肩峰支沿途发出3～5支、外径0.3～0.5mm的骨膜支分布锁骨中外段后参与肩峰网形成;其长度5.1±0.4crn、外径1.2±0.2mm。锁骨支有1～3支、外径0.2～0.5mm的骨膜支分布锁骨中内段;其长度2.0±0.1cm、外径1.2±0.2mm。结论:可设计以胸肩峰动脉肩峰支蒂逆行锁骨骨膜(骨)瓣转位修复肱骨近端的新术式。
Objective: To provide a new surgical approach to repair the proximal humerus. Methods: Forty adult cadaver specimens were examined for the movement, branching and distribution of the thoracic-to-pulmonary artery. Results: Three to five branches of the thoracolumbar and the branch of periapical branch were formed. Periosteum of 0.3-0.5 mm in diameter was distributed in the middle and outer segments of the clavicle. The length of the periosteal branch was 5.1 ± 0.4 cm and the outer diameter was 1.2 ± 0.2 mm. Clavicular branch has 1 to 3, the outer diameter of 0.2 ~ 0.5mm periosteal branch distribution within the clavicle; its length 2.0 ± 0.1cm, diameter 1.2 ± 0.2mm. CONCLUSIONS: A new surgical approach to repair the proximal humerus with retrograde clavicular periosteum (flap) transposition of the acromioclavicular branch of the thoracolumbar arteries can be designed.
