With the introduction of interventional cardiology in the late seventies and the significantly improved techniques in cardiac surgery, anaesthesia and intensive care medicine, the surgical candidate has shifted from a more or less healthy patient with a cardiac problem to a multimorbid one with a serious cardiac disease. B 5 implants applied as recommended by the manufacturer. Additional implants were loaded in the same manner and subjected to exaggerated, dynamic loading intended to mimic physiologic conditions for up to one million cycles - representing over six weeks of respiration. At the time of surgery, the type of sternal closure was designated according to cumulative preoperative risk factors as well as sternal quality, e. Both were first loaded statically in tension until failure to determine their strength. The needles are cut after each placement.

In between the profession has changed dramatically. The above listed comorbidities have crucial impact on bone architecture, composition of corticalis and spongiosa. All authors read and approved the final manuscript. The mechanical function of the system was characterized by the manufacturer with assessment of strength and durability zipfixx compared to USP 5 stainless steel surgical wire for sternal closure.

Closure was performed by two senior consultants. In addition if stability can be improved even in extreme situation such as mechanical reanimation, some extra cost of reoperation for sternal refixation could be zipfid.

It primarily consists of biocompatible Poly-Ether-Ether-Ketone implants and is predominantly used peristernally through the intercostal space. This article presents a very promising technique that is new for sternal closure, but is otherwise well-known in various fields — the cable tie principle, which is incorporated in the Synthes ZipFix TM —implant Synthes GmbH, Oberdorf, Switzerland.

Follow-up costs remain a considerable burden on health care systems [ 56 ]. Results 50 patients were closed with the ZipFix TM system.

Postoperatively, 2 female patients had to be zipfis resuscitated. Conclusions In our initial evaluation, the short-term results have shown that the sternal ZipFix TM can be used safely and effectively.

However our initial short-term results demonstrated, in a small group of patients, the safe and effective use of the sternal ZipFix TM System. Conclusion However our initial short-term results demonstrated, in a small group of patients, the safe and effective use of the sternal ZipFix TM System.

A Fatigue test with exaggerated, dynamic loading intended to mimic physiologic conditions and B simulation of bone cut-through of three different implants. Compared with wires, these steel bands not only provided effective fixation, they demonstrated a reduction in postoperative pain and length of postoperative hospital stay [ 78 ].

Both patients were suffering from metabolic syndrome with a BMI of 40 and 35 respectively, as well as insulin-dependent diabetes and chronic renal failure under hemodialysis.

In our initial evaluation, the short-term results have shown that the sternal ZipFix TM can be used safely and effectively. Initial tests performed by Synthes demonstrated the superior fatigue strength of sternal ZipFix TM compared with stainless steel cerclage wires. Indeed, 2 patients developed mediastinitis that necessitated removal of the ZipFix TM at day 24 and 30 in association with administration of antibiotics. The device has been designed to be best applicable for sternal closure.

The force is concentrated on a very tiny surface length of the wire, which then can act like a knife. Procedures and anesthesia are faster, less invasive, less harmful, and medication is more target-oriented. After the removal of the needle the end is inserted into the locking head. Each device was prepared in test fixtures to simulate peristernal application and subjected to lateral loading. We present a new tool for sternal closure with its first clinical experience and results.

Additionally, the lack of sharp edges might be less vulnerable to the periostium. The author declare that they have no competing interests.
