Abstract
OBJECTIVES
In elderly patients the temporary loss of function of the upper extremity due to immobilization for treatment of unstable proximal humeral fractures is a very disabling condition. Stable fixation of such fractures allowing immediate functional aftercare may contribute to early social reintegration in this group of patients. Aim of this study is to present the surgical technique of humeral blade plate fixation and the clinical and radiographic results after fixation of unstable surgical neck fractures with this implant followed by immediate functional treatment in patients older than 60 years.
PATIENTS
20 patients (4 male, 16 female) with a mean age of 74 years (59y–93y) were included in this study and treated consecutively for an unstable/displaced surgical neck fracture with a humeral blade plate. Postoperatively functional treatment was allowed. All but one patient had a clinical and radiographic follow-up 6 weeks po. At an average final follow-up of 18,8 months (12–24 months) 4 patients had died from causes unrelated to surgery.
RESULTS
Surgery was performed in all patients without local or general complications despite comorbidities. In all patients anatomic reduction and stable fixation could be achieved. 6 weeks po all patients (N=20) were free of pain at rest, 7 patients had low pain (VAS < 4) when actively moving the arm. All patients used their operated arm for ADL and were back home or in the institution they came from at the time of trauma. All fractures were deamed to be healed without implant failure. In two cases a clinically asymptomatic 1–2mm protrusion of the blade through the subchondral bone was observed, but did not required further surgery. At final follow-up (N=8) the average absolute Constant/Murley Score was 68,6 points (contralateral 71,4). Radiographically all fractures had healed without complications. Implant removal was not required.
CONCLUSION
Humeral blade plate fixation combined with suture tension-banding of the rotator cuff allows indirect reduction, dynamic and stable osteosynthesis of unstable surgical neck fractures even in osteoporotic bone. In our small series, this technique has shown to be a safe and reliable therapeutic option allowing immediate functional treatment and thus early social reintegration in elderly patients.
