Posterior percutaneous plating of the humerus.
OBJECTIVE
This is a prospective case series study, which was designed to evaluate the clinical outcome of posterior percutaneous plating of the humerus.


METHODS
From the year 2010 to 2011, 37 patients with middle and distal third humeral fractures who met the inclusion criteria were surgically treated by minimally invasive plate osteosynthesis through posterior approach. Their age ranged from 19 to 43 with an average of 27.8 years. Type of fractures varied from B to C, and all of them were traumatic.


RESULTS
Patients were followed up for a period varied from 12 to 24 months with an average of 18. There were no cases of intraoperative complications, infection or metal failure. Union was achieved in all of them within 16-21 weeks with an average of 18. Iatrogenic postoperative temporary neuropraxia of the radial nerve palsy was observed in two patients. All patients achieved normal range of shoulder and elbow motion within 3 months after surgery. The average Quick DASH score at 12-month follow-up was 30. According to patient's satisfaction, all of them returned to the usual pre-injury activity level within 6 months.


CONCLUSIONS
This study suggests that the principles of minimally invasive plate osteosynthesis can be applied safely through posterior approach of the humerus to treat middle and distal third humeral fractures. This approach has the advantage of preserving the triceps anatomy and function facilitating rapid postoperative rehabilitation.
