Percutaneous fixation with Schanz screws for displaced two- and three- part fractures of the proximal humerus in patients above fifty years of age.

Abstract

PURPOSE:

The aim of this study is to evaluate whether two 3.0 mm Schanz screws in two-part proximal humeral fractures (plus one additional Schanz screw or K wire in three-part fractures) can provide enough stability to allow early mobilization until healing occurs in elderly patients.

SETTINGS AND DESIGN:

This prospective study was performed in the Orthopaedic Department of our University Hospital.

PATIENTS AND METHODS:

We performed closed reduction and percutaneous pinning for thirty-three patients with proximal humerus fractures. Twenty-seven patients were available for the final follow-up. Of those 27 patients, 17 had two-part surgical neck fractures; while 10 had three-part fractures. For fixation, we used two 3.0 mm Schanz screws in patients with two-part fractures plus one additional Schanz screw or K wire in the 10 patients with three-part fractures.

RESULTS:

The mean Constant score modified according to the age and sex was 89.8% (range: 77.3-97.2%). Fifteen patients had excellent results, 11 patients had good results, and one patient had a fair result.

CONCLUSION:

Closed reduction and percutaneous pinning with two Schanz screws for two-part surgical neck humeral fractures, plus an additional Schanz screw or K wire for three-part proximal humeral fractures is a useful and effective technique that provides enough stability to allow an early rehabilitation program till union occurs in elderly patients.

LEVEL OF EVIDENCE:

IV; therapeutic study, case series.
