Radiographic Evaluation of the Consolidation of Humerus Surgical Neck Fractures Treated With Percutaneous Fixation^*

Abstract

Objective

To evaluate radiographically the postoperative results of patients with fracture of the proximal humerus in two parts of the surgical neck treated with threaded percutaneous fixation.

Methods

We evaluated the radiographic results of percutaneous fixation with threaded pins on the treatment of proximal humerus fractures in our service. Preoperative and postoperative images of 42 patients were evaluated, evaluating radiographs until 8 weeks postoperatively. We considered on evaluation the fracture deviation on preoperative images, the loss of reduction and no consolidation.

Results

Our consolidation rate was 90.4%, with loss of reduction in 16.6% of the cases and no consolidation rates in just 4 operated cases. We observed a predominance of a specific fracture pattern in the cases with loss of reduction.

Conclusion

The present study allows us to consider the percutaneous fixation technique with threaded pins as an alternative in our therapeutic arsenal for the proximal humerus fracture of the surgical neck. Contraindications are considered for low fracture trait on the metaphysis and with medial/lateral cortical impairment.
