title: [Clinical efficacies of different internal fixation materials in the treatment of senile proximal humerus fractures].
abstract: OBJECTIVE
  To explore the clinical efficacies of different internal fixation materials in the treatment of senile proximal humerus fractures.
  
  
  METHODS
  A total of 284 hospitalized patients of proximal humerus fractures over 60 years of age cases from October 2009 to February 2012 were randomly divided into two groups of locking proximal humeral plate (LPHP) and PHILOS (n = 142 each). And the clinical efficacies of two groups were compared.
  
  
  RESULTS
  For PHILOS and LPHP groups, the fracture healing periods were (11.64 ± 3.81) and (14.95 ± 3.95) weeks. And there was statistical significance (P < 0.05). At 3 months post-surgery, the incidence of pain was 72.41% and 64.81%. And there was statistical significance (P < 0.05). At 2 years,Neer shoulder function score had inter-group statistically insignificant difference (P > 0.05).
  
  
  CONCLUSIONS
  Both PHILOS and LPHP are effective in the treatment of senile proximal humeral fractures.However, the former is conducive to fracture healing and has shorter healing time and lowered postoperative pain.
