Brief Summary:
The primary objective is to establish if the SternumFix System improves sternal closure. The study should test the hypothesis that in a high risk patient population with increased risk for the development of sternal wound complications SternumFix will reduce the incidence of sternal healing complications. The control group will be treated with wire cerclage, the standard method of sternal closure.

Condition or disease Intervention/treatment Phase
Sternum Wound Infection Nonunion of Fracture of Sternum Device: Sternumfix Procedure: steel wire Phase 4

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 166 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single (Participant)
Primary Purpose: Treatment
Official Title: Multicenter Controlled Study on the Safety and Efficacy of Sternal Closure With STERNUMFIX in Patients With High Risk
Study Start Date : June 2008
Actual Primary Completion Date : August 2012
Actual Study Completion Date : November 2012

Arm Intervention/treatment
Experimental: Sternumfix
sternotomy closure with Sternumfix
Device: Sternumfix
sternotomy closure with Sternumfix

Active Comparator: Steel wire

Procedure: steel wire

Primary Outcome Measures :
  1. cumulative three-months incidence of re-operation rates due to sternal instability or infection for patients with SternumFix in comparison to sternal fixation with wires in a high risk patient population [ Time Frame: within three months ]

Secondary Outcome Measures :
  1. Adverse event rate. Postoperative chest pain. Length of postoperative hospital stay. Blood loss within the first 12 hours p.o. Duration of the sternal fixation. [ Time Frame: within 3 months ]

Accepts Healthy Volunteers:   No


  • Patients undergoing elective cardiac surgery with a median sternotomy
  • Age >18 years
  • Male and female sex
  • Informed consent
  • Patients with high risk for sternal wound complications

Patients are designated as high risk patients if they have either:

  • one or more major risk factors or
  • four or more minor risk factors.

Major risk factors are:

  • Obesity: BMI > 30.
  • Diabetes: intake of oral anti-diabetic drugs and/or insulin at time of surgery.
  • COPD: history of chronic coughing plus expectoration for at least 3 months by at least two consecutive years, plus evidence of restrictive pattern at spirometry.
  • Planned BITA: bilateral use of thoracic artery
  • Age > 75 years

Minor risk factors are:

  • History of smoking;(minimum of 1 year of history of smoking)
  • Hyperlipoproteinaemia (as stated in the patient data)
  • Planned surgery is a CABG
  • Patient is on dialysis
  • Repeat sternotomy
  • Left ventricular ejection fraction < 30% (as stated in the patient data)
  • Male sex


  • Active infection
  • Participation in a pharmaceutical clinical study or any trial with interfering endpoints within the last 30 days
  • Pregnancy
