Proximal Humerus Humerus Surgical Neck Fracture

Objective:The aim of this study was to evaluate the clinical results of locking proximal humerus plate (LPHP) in the treatment of humerus surgical neck fracture.Method:We retrospectively reviewed twenty-three patients with humerus surgical neck fracture who received treatment between January2010and December2011. All patients were closed and fresh fractures with the treatment of locking proximal humerus plate. The mean interval between injury and surgery is6.7days (2～18days). X-rays were taken at pre-operation, post-operation, periodical time after operation and the latest follow-up. The clinical results were evaluated according to Neer score.Results:23patients were followed for12.5months on average (2～17months). All of the fractures were healed in8～14weeks(average8.6weeks). According to Neer scores, the results of shoulder function were excellent in14cases, good in6cases, unsatisfactory in3cases, poor in0cases, the good rate was86.9%.1patient was incisional wound infection after internal fixation, the infection was controlled after debride and drainage. There were no complications of flexible internal fixation, displacement fracture, malunion, nonunion or other nerves as well as vessels. Conclusions:Displaced proximal humeral fractures which include two-part, three part and four part can be successfully fixed with locking proximal humerus plates. The patients can obtain satisfactory results combining perennial and perfect rehabilitation. Otherwise, a longer follow up and observation is necessary.
