Module 2 Flashcards
(11 cards)
What’s the difference between bipolar and mono polar
Bipolar ablation is when the radiofrequency from the
console generates an electrical field at the tip of the
probe.
Monopolar ablation is when the electrical current
flows through the body from the active electrode
at the surgical site and exits at the return electrode
(grounding pad).
What the highest setting on the Apollo i90
3000
What is allosync – where can It be used and what varieties does it come in
Human allograft bone. Provides optimal signal and scaffolding for bone remodel. Can be used in any location where we are wanting to increase bone healing.
Varieties: Chips, Fibers, Cubes, Strips
Discuss Anatomy of Achilles tendon. Know which muscles make up, understand the watershed area and where Achilles inserts on Calcaneus, and what neurovascular structure runs along side
Muscles that make up Achillies: Gastroc & Soleus.
Inserts on middle third of calcaneal tuberosity
Neurovascular structure: Sural nerve
Watershed Zone: Hypovascular area in the mid-section of Achillies. Rutpure occurs here about 75% of the time. 2-6 cm from attachment point on calc.
Complete a MIS Achilles Speedbridge on sawbone and discuss the features and benefits of the new kit
Features and Benefits:
* 2.6 mm DX Knotless FiberTak anchors and 3.9 BioComposite SwiveLock anchors
* NEW 1.7 mm collagen-coated FiberTape® suture with differentiating colors
* 25% less material than the traditional Achilles SpeedBridge construct
* Double the biomechanical strength of the 4.75 mm SwiveLock SpeedBridge construct, with knotless
tensionable technology to create a rip-stop
* Cannulated instruments for a percutaneous approach

Demo Fiber tape Cerclage – list features and benefits, ultimate load. What should you tension to in both disposable and reusable
Ultimate load – 3300-4700
Features & Benefits:
1. Broad footprint can help reduce or eliminate tissue/bone cut-through
2. Low-profile to help minimize tissue irritation and may allow for plating over the tapes
3. Radiolucent to better ascertain healing of the fracture
4. No sharp edges
5. Simple tensioning system eliminates the need for large instruments on the sterile field
Avoid tensioning above 80
Walk surgeon through using 1.8 knotless fibertak and discuss features and benefits. (KNOW the Guide options, new guide vs old, drill sizes)
Features and Benefits
* Increased anchor strength and more consistent fixation
* Enhanced suture color and handling characteristics
* Smoother, suture shuttling and tensioning
* Premium instrumentation with additional stability into a 1.8 mm drill hole
Applications in: foot, ankle, knee, hand, wrist, elbow, shoulder, and hip
Guides:
Old guides: AR-1948CT
New Guides: AR-3610F, AR-3610CT, AR-3610SC, AR-3610CTC, AR-3610CTC2,
Discuss Meniscal Anatomy, its attachments and blood supply. What is the function as it relates to hoop stress and name 3 different techniques to fix
Attachments:
Medial: Tibial Plateau Anterior to ACL, Posteror root: Anterior to PCL
Lateral: Posterior to ACL, Anterior to Medial posterior root
Blood Supply- Red-Red, Red-White, White, White
Hoop stress: weight is evenly distributed across menisci. With tear, weight is transfered to articular surface
Fiberstitch: whats the diameter of needle, what suture is made of, what is the depth stop preset at
Needle is 1.5mm. Uses 2-0 fiberwire suture. Depth stop is preset at 12 for Fiberstich RC. Or 18mm and can be adjusted down to 10mm by 2mm increments for other fiberstich.
Demonstrate Anatomy of AC joint. Perform AC Dogbone on sawbone
Acormioclavicular joint. Ligaments: AC ligament (4 bands, Anterior Posterior Inferior and superior), Coracoclavicular ligament (two different ligaments: Trapazoid 2.5cm medical to AC, conoid ligament 4.5cm medial to AC).
