The experimental stady of new clavicle flap transpo-sition for the repair of ischemic necrosis of femoral head and nonunion of proximal end

AIM：To provide a new way of operation for repairing fracture necrosis of proximal humerrus.METHODS:Observing the course,branches and distributions of thoracoacromia artery on 40 sides of abult cadaveric.RESULTS:(1)Sending off 3 to 5 periosteal branches with diameter of 0.3 to 0.5mm along the acromial branch of thoracoacromial,which distributed at the middle outboard and formed the part of acromial artery net.The acromial length was (5.1±0.5)cm with diameter of (1.2±0.2)mm.(2)Sending off 1 to 3 periosteal branches with diameter of (0.2 to 0.5)mm from the clavicular branches of thoracoactomial artery,which distributes at the inside part one second.The length was (2.0±0.1)cm with diameter of (1.2±0.2)mm.CONCLUSION:A new operation can be designed for repairing fracture necrosis of proximal humerus by transposing clavicle periosteal(bone) flap with the acromial branch of toracoacromial artery.

AIM: To provide a new way of operation for repairing fracture necrosis of proximal humerrus. METHODS: Observing the course, branches and distributions of thoracoacromia artery on 40 sides of adult cadaveric. RESULTS: (1) Sending off 3 to 5 periosteal branches with diameter of 0.3 to 0.5 mm along the acromial branch of thoracoacromial, which distributed at the middle outboard and formed the part of acromial artery net. The acromial length was (5.1 ±0.5) cm with diameter of (1.2±0.2) mm. (2) Sending off 1 to 3 periosteal branches with diameter of (0.2 to 0.5) mm from the clavicular branches of thoracoactomial artery, which distributes at the inside part one second. The length was (2.0±0.1) cm with diameter of (1.2±0.2) mm. CONCLUSION: A new operation can be designed for repairing fracture necrosis of proximal humerus by trans- posing clavicle periosteal (bone) flap with the acromial branch of tora- coacromial artery.
