Titanium Sternal Fixation System. For stable internal fixation of the sternum. The DePuy Synthes Titanium Sternal Fixation System provides stable internal fixation of the sternum following a sternotomy or fracture of the sternum. Broad variety of sternal plates Different titanium plates according to the anatomical structures and patient’s need are available: – Straight locking plates for a stable sternal rib-to-rib fixation – Sternal body plates for minimal dissection – Star-shaped and H-shaped locking plates for fixation of the manubrium – Titanium sternal locking straight plate without...

Titanium Sternal Fixation System Self-tapping and self-drilling locking screws Both self-tapping and self-drilling locking screws are available to accommodate surgeon preference. Secure and stable locking The plate functions like an external fixator, applied internally. The screwhead of the sternal locking screws locks securely into the threaded plate hole to provide stable fixation (Figure1). Emergency release pin on all plates‡ All plates consist of two parts joined by a U-shaped release pin in the cross section. The release pin allows a quick and easy sternal reentry in cardiac emergency...

Primary or secondary closure/repair of the sternum following sternotomy or fracture of the sternum, to stabilize the sternum and promote fusion. Warnings: – hese devices can break during use (when subjected to T excessive forces or outside the recommended surgical technique). While the surgeon must make the final decision on removal of the broken part based on associated risk, in doing so, we recommend that whenever possible and practical for the individual patient, the broken part should be removed. – edical devices containing stainless steel which may M elicit an allergic reaction in...

Surgical Technique 1 Position patient Position the patient with the arms tucked along the sides. Avoid placing arms at 90° on arm boards, as this makes chest closure more difficult. 2 Debride (for secondary closure of the sternum) Remove existing wires. Debride the involved sternal edges until they are free of devitalized tissue and down to bleeding tissue. Hemostasis should be obtained. A curette can be used to remove any nonviable cartilaginous rib. Precautions: A sternal bone specimen should be sent to pathology to assess for osteomyelitis. Antibiotic treatment should be based on the...

Surgical Technique 3 Expose ribs laterally, if necessary Beginning medially, elevate the pectoralis major muscles with overlying soft tissue attached to create flaps and permit later approximation in the midline. It is usually not necessary to perform a second incision at the shoulder to release the pectoral muscle insertion. Following debridement and muscle elevation, pulse lavage the entire surgical site with an adequate volume of saline with antibiotics. 4 Measure sternal edges Instrument 319.11 Depth Gauge Using the depth gauge, measure the sternal edges adjacent to each rib where a...

Reduce sternum 398.903 Sternal Reduction Forceps, angled, with teeth 398.985 Bone Reduction Forceps, large Reduce the sternum using reduction forceps on both the superior and inferior aspects of the sternum. When placing the forceps, care should be taken to avoid the intercostal and mammary vessels and nerves. Alternative instrument 398.902 Sternal Reduction Forceps Note: Sternum can also be reduced with stainless steel surgical wire, if desired. Precaution: Avoid direct contact of stainless steel wires with titanium implants to avoid galvanic corrosion. 6 Cut and contour template...

Surgical Technique 7 Select plate Instrument 319.990 Plate and Rod Cutter Select the appropriate length titanium sternal locking plate. Center the release pin on the sternum with sufficient plate length on each side to allow a minimum of four locking screws on each side. The plate can be cut to length, if necessary, using the plate and rod cutter. Alternative instrument 391.967* Shortcut Plate Cutter (2 required) As an alternative, shortcut plate cutters may be used. Note: All steps of preparation and implantation of the Sternal Locking Plate have to be done, whenever possible, with the...
