Open Posterior Lumbar Spinal Fusion Surgery
During spinal fusion procedures, you want to limit damage to the soft tissue surrounding the spine as much as possible. With less tissue trauma, less inflammation will develop after the procedure, which can mean less perceived pain and less postoperative discomfort for the patient.
HARMONIC SYNERGY® Blades offer surgeons a new choice for gaining exposure to orthopedic structures like the spine. After the skin incision is made, usually with a steel scalpel, the HARMONIC SYNERGY Blade Device can be used to cut and coagulate soft tissue. Because it uses mechanical energy that cuts at a temperature at or under 100 degrees Celsius, there is minimal thermal spread and desiccation of the tissue.*
DERMABOND™ PRINEO™ Skin Closure System provides a triad of benefits that can help you achieve excellent results
- STRONG – supports skin closure with strength equivalent to 3-0 MONOCRYL™ (poliglecaprone 25) subcuticular sutures ex vivo1
- EFFICIENT – may reduce final layer of skin closure time by up to 75%1
- PROTECTIVE – provides a flexible microbial barrier in vitro1
STRATAFIX™ Knotless Tissue Control Devices – a unique anchoring technology to maintain closure without knots:
- More consistent tension control and approximation with each pass than with traditional sutures
- Strength and security of interrupted suturing without knot-related complications1,122,123,133,141,145,150,153
- More efficient than continuous suturing with traditional sutures1,122,123,133,141,145,150,153
MONOCRYL™ Plus Antibacterial (poliglecaprone 25) Sutures provide benefits required for ideal subcuticular skin closure
- Provides strength through critical healing period (5-7 days)
- Protection against bacterial colonization of the suture by organisms commonly associated with surgical site infections
- Monofilament design that passes smoothly through tissue186,187

The difference was significant (p < .001).1
An advanced energy device for spinal fusion surgery, HARMONIC® Technology is designed to offer you better soft tissue management.
The HARMONIC® Blades use advanced ultrasonic energy to precisely cut and coagulate soft tissue resulting in reduced acute inflammation and tissue damage.
How it works:
- The handset converts electricity into longitudinal motion, making the blade vibrate at 55,500 Hz.
- This low frequency ultrasonic energy creates cellular friction when applied to soft tissue.
- Amino acids in the protein reshape and hydrogen bonds break down.
- The amino acids reform into a sticky coagulum that reliably seals small vessels – and it does it at a temperature under 100 degrees Celsius.†
With the HARMONIC Blades, you benefit from:
- Reduced blood loss due to effective coagulation.‡
- Minimal lateral damage and desiccation of soft tissue due to the device’s lower operating temperature.†
- Reduced trauma because energy is applied parallel to the applied force.11
- Less acute inflammation processes. Acute inflammation has been linked to a patient's increased perception of pain.*
- No electricity to or through your patient.

- *In a pre-clinical study, necropsy and histological evaluations indicated a significant reduction in acute inflammation for skeletal muscle wounds created by the HARMONIC Blade vs. monopolar electrosurgery at 3, 7, and 21 days post-op (p value = 0.011 for all post-operative periods).1
- Per NIH, the definition of inflammation is "A response of redness, swelling, pain and a feeling of heat in certain areas that is meant to protect tissues affected by injury or disease." (http://ghr.nlm.nih.gov/glossary=inflammation)

- ‡In a vessel sealing comparison, the HARMONIC Combination Blade sealed more 1-2 mm vessels than electrosurgery. Study conducted in porcine mesentery. In a pre-clinical study, porcine mesentery was used to compare the number of 1-2 mm vessels coagulated while cutting. The HARMONIC Hooked Blade ("HK105", power level = 5) was compared to steel scalpel and monopolar electrosurgery (power level = 40W blend 1). The steel scalpel sealed zero of 20 vessels (0%), electrosurgery sealed 3 of 70 vessels (4.3%), and HARMONIC® HK105 sealed 64 out of 68 vessels (94.1%). Statistical analysis indicated that HARMONIC® HK105 sealed significantly more vessels while cutting than either the steel scalpel or electrosurgery (p < .001).1
