Dual plate fixation of proximal humerus fractures: Retrospective review and surgical technique.

INTRODUCTION

Recent interest has been directed towards dual plate fixation for comminuted proximal humerus fractures, with an aim to improve construct stability and thus improve patient outcomes while decreasing the risk of fracture-associated complications. We present our experience with this technique in a case series of patients with proximal humerus fractures and describe our surgical technique.

METHODOLOGY

This was a single-center retrospective case series of patients presenting with an acute (<6 weeks) proximal humerus fracture who underwent ORIF with dual plating fixation. Patient, fracture, and surgical data were collected. All patient outcomes were evaluated using Constant-Murley shoulder score and Single Assessment Numeric Evaluation.

RESULTS

Our series included nine patients with a mean age of 46.2 years (range: 27-70 years old). All fractures healed within 4 months and no complications were encountered. At 1 year follow-up, the mean SANE score was 69.4% and the mean Constant Murley shoulder score was 78.9 (range: 70-96).

CONCLUSION

Our current series shows that applying the dual plating technique in severely comminuted proximal humerus fractures provides adequate fixation and thus good patient outcomes. Further research is required before this technique can be strongly recommended for management of these complex fractures.
