title: Treatment of proximal humeral fracture with a proximal humeral nail.
abstract: BACKGROUND
  Various treatment options are available for displaced proximal humeral fractures. This study monitored a series of patients treated with a locking proximal humeral nail (PHN).
  
  
  OBJECTIVE
  Fixation with a PHN can be an effective method when treating patients with two part surgical neck fractures of proximal humerus.
  
  
  METHODS
  PHNs were used to surgically repair humeral neck fractures in 22 patients. Factors affecting the final function were analyzed by multiple linear regression.
  
  
  RESULTS
  Mean patient age at the time of surgery was 56.9 years. The mean follow-up was 25.4 months, and all fractures united within 8 weeks. The average active forward flexion was 147.3 degrees , the average external rotation was 44.1 degrees , and the average internal rotation was T10. All patients were satisfied with their results. Two factors associated with patient American Shoulder and Elbow Surgeon scores were patient age and the strength of the supraspinatus.
  
  
  CONCLUSIONS
  Details in patients choosing and surgical management were discussed.
  
  
  CONCLUSIONS
  Closed reduction and internal fixation with a PHN can be an effective method for the treatment of 2-part surgical neck fractures.
