BackgroundVarious treatment options are available for displaced proximal humeral fractures. This study monitored a series of patients treated with a locking proximal humeral nail (PHN).HypothesisFixation with a PHN can be an effective method when treating patients with two part surgical neck fractures of proximal humerus.Materials And MethodsPHNs were used to surgically repair humeral neck fractures in 22 patients. Factors affecting the final function were analyzed by multiple linear regression.ResultsMean 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.DiscussionDetails in patients choosing and surgical management were discussed.ConclusionClosed reduction and internal fixation with a PHN can be an effective method for the treatment of 2-part surgical neck fractures.Copyright 2010 Journal of Shoulder and Elbow Surgery Board of Trustees.
