BONY NECKTIE: A BIOLOGIC SOLUTION TO RESTORE TUBEROSITY POSITION (CUFF TENSION) IN REVERSE SHOULDER TRAUMA PROSTHESES

Abstract

Purpose: The three dimensional position of the tuberosity and the tension of the rotator cuff influence the structural changes of the rotator cuff and their influence on clinical results of reversed trauma prostheses.

We propose this technique with it of a biological support, the fractured humeral head, adequately modeled, in order to give again the just tension to the cuff

Method: from February 2007 and February 2009 we treated 29 patients with a reversed trauma prostehes, in 7 cases we have practiced the bony necktie, for giving a support to the correct reconstruction of the tuberosity. The patients have an average of 71,5 years and was evaluated with Constant score and radiographic study with mean follow-up of 18,6 months

Results: Improvement of postoperative Constant score and radiographic good results were correlated with satisfactory subjective results. However, these results will have to be confirmed with more cases and later revision

Conclusion: Tuberosity position and healing is critical for clinical and radiographic outcome in shoulder arthroplasty in trauma. In particular the rate resorption of the tuberosity in Reverse Trauma Prostheses still is elevated. we propose a new surgical technical in order to give again the just position to the tuberosity fractured and therefore to give tension to the rotator cuff
