Proximal humeral fractures accounts for about 26 ﹪ in shoulder fracture, and accounts for about 4~5﹪ in the whole body fracture. It is more common in the elderly population, accounting for one-third of elderly fractures. It may be caused by direct violence, convey violence, electric shock, or epilepsy which irregular muscle contractions cause. For children, it could easily cause epiphyseal slippage, for young adults it leading to dislocation, while for the elderly it being prone to cause fractures. After conservative treatment, most patients can get good results with rehabilitation exercises.
Type A fracture: Non-displaced fracture of the proximal humerus account for 85% of all, more common in people over the age 60. Bandage or plaster suspended is suggested.
Type B fracture: Common surgical neck and greater tuberosity avulsion fracture.
Type C fracture: Common surgical neck fractures combined greater tuberosity avulsion fracture and displacement.
Type D fracture: (1) Severe soft tissue injury,
(2) Serious damage to the blood supply,
(3) Humeral head necrosis rate is high,
(4) Surgical complications,
(5) Slow functional recovery,
(6) For over 60 years elderly patients hemiarthroplasty is surgical indications.
