ANESTHETICS
Esters • Higher incidence of allergies • Metabolized in Blood (Cholinesterase in plasma) • Types
~ Cocaine ~ Procaine ~ Chloroprocaine ~ Tetracaine
Amides • Metabolized by CYP450 system in Liver • Types
~ Lidociane / Xylocaine (0.5, 1, 1.5, or 2% solutions) ~ Bupivicaine / Marcaine (0.25, 0.5, or 0.75% solutions) "* C/I<l2y/0
~ Mepivicaine / Carbocaine (1, 1.5, 2, or 3% solutions)
0.5% solution = 5 mg/cc drug 1% solution = 10 mg/cc drug
Ex: 5cc of 1% Xylocaine (lidocaine) = 50mg of Xylocaine given Ex: 3cc of 0.5% Marcaine (bupivicaine) = 15mg of Marcaine given
Dosing: 0.25% solution = 2.5 mg/cc drug lcc = lmL
Toxic Doses: Lidocaine Plain = 300mg
w/ Epi = 500mg
Onset & Duration: Onset: 5min Duration: l-2h
Marcaine Plain = 175mg Onset: 10-15min w/ Epi = 225mg Duration: 6-8h

6 Ways to Increase Comfort of the Injection: 1. Quick Stick 2. Slow Injection 3. Small Gauge Needle (large # = small gauge) 4. Small Syringe (less pressure) 5. Cold Spray 6. Warm the Solution (to body temp)
Draw up with 18G Inject with 25 or 27G
Ankle Ring Block: Superficial = Saphenous N., Sural N., Superficial Peroneal N. (IDCN.MDCN)
Deep = Posterior Tibial N., Deer Peroneal N.
** Fact: If you mix Lidocaine and Marcaine, you will only have partial anesthesia deep into surgery. Only mix to avoid toxic doses.

CORTICOSTEROID INJECTIONS Corticosteroid injections are used to control local inflammatory reactions
Phosphates: short-acting (clear) Acetates: long-acting (cloudy)
All corticosteroids are collagenilytic and therefore should not be injected into the same area of soft tissue more than 3-4 times per year.
Side Effects: ~ Soft tissue atrophy ~ Tendon rupture ~ Skin discoloration (lightening)
Cocktails Commonly used in Podiatry: Always draw up the Lido/Marc 1" 1. Plantar Fasciitis j followed by Dex or Kenalogl

INTERNAL FIXATION
4 Main Principles of Internal Fixation: 1. Anatomical Reduction 2. Rigid Internal Fixation 3. Atraumatic Technique 4. Early active RoM
Rules of 2's: • Fracture / Osteotomy site should be • 2 points of fixation is better than 1 • 2 threads should purchase the distal • 2 finger tightness
Kirschner Wires (K-wires): • Steel wires used as permanent or temporary fixation • Dependent on diameter • Available in both smooth and threaded • Threaded wires provide more stable purchase • BUT are weaker & harder to remove • Both are measured by outer diameter • ONLY maintain compression • Sizes: 0.028, 0.035, 0.045, 0.062 inches
Steinmann Pins: • Very similar to K-wires • Larger diameter than K-wires • Provide Inc Stability • Measured in 64ths • Sizes: 8/64 (1/8), 7/64, 6/64...
2x's the diameter of the bone
cortex
34
INTERNAL FIXATION CONTINUED
Monofilament Wire: • Malleable Steel • Provide interfragmentary compression » Measured in Gauges (small gauge = large diameter) • Techniques:
> Cerclage fashion • circling around a bone
> Interfrag fashion • placed in between 2 fragments • always pull on the proximal fragment • most stable
35
INTERNAL FIXATION CONTINUED.
Monofilament Wire Continued... > Box Wire fashion
• 2 boxes at 90° to each other • One wire is placed medial to lateral • Other is placed dorsal to plantar
Tension Band Wiring: • Combines K-wire with MF wire • Requires that there is a soft tissue structural component • Two K-wire's placed the parallel fashion across fracture site with the
MF wire in a figure 8 pattern around the K-wire on the site opposite to the tendon's anatomical pull.
• Size of wire measured in gauges — Lower gauge; thicker wire • 26 & 28 are common in Podiatry
36
INTERNAL FIXATION CONTINUED. . .
Staples: • Primarily used for fractures, osteotomies & fusions • Inserted manually or with pneumatic gun • Provide compression, distraction or maintain compression • Be careful about thickness of bone - DO NOT use if cortical bone is
greater than 2-3mm, may cause cortical fractures or not seat in bone properly
Pre-Drills:
Neutralization-^
Compression 4 : Divergent Lines
Distraction = Convergent Lines
Richards Staple: GOLD STANDARD for major fusion Os Staple: Heat activated Uniclip: Has an aperture
Requires a tool to compress the legs after insertion

INTERNAL FIXATION CONTINUED. . .
Screws: These features can differ depending on the function of the screw.
Flead Has various configurations; hexagonal, cruciate, slotted...
Land The curve-contoured underside of the screw head Increases the surface contact between the screw and the bone Reduces the chance from stress-risers
Shaft/Shank Area of the screw that is void of the thread pattern
Thread The means by which the screw purchases the bone
Thread Diameter The diameter across the thread width
Measurement is the value used to describe the screw size
Core Diameter Diameter between the thread patterns
Pitch Distance between the adjacent threads Run-Out Junction where the shaft meets the thread
Weakest point on the screw
Avoid placing the run-out near the fracture / osteotomy site
Lead Distance that the screw advances with each turn (360°)
Rake Angle Thread to axis angle

INTERNAL FIXATION CONTINUED . . .
Types of Screws:
1. Cortical Screws • Threaded the entire length of the screw • Have smaller pitch for greater number of contacts between the
screw and the dense cortical bone
2. Cancellous Screws • Partially threaded • Larger pitch to provide greater distance of contact between the
screw and the less dense, porous cancellous bone
3. Cannulated Screws • Hollow center down the length of the screw to be used over a guide
wire • Offers easier placement and less complications • May have decreased pullout strength
4. Herbert Screws • Ho head and two set of threads proximally not distally • Proximal threads have greater pitch than the distal threads • Indicated for intra-articular fractures • Compressive strength of Herbert screw are less than conventional
screws
5. Interference Screws • Fully threaded, headless screw • Does not provide interfragmentary compression but resists axial
displacement of one fragment on another • Indicated for stabilization of tendon grafts to bone and tendon
reattachment

INTERNAL FIXATION CONTINUED. . .
Types of Screws Continued:
6. Absorbable Screws • Available in natural / synthetic polymers • Most common absorbable polymers used are based on alpha-

Basic Properties for the Ideal Absorbable Implant: ~ Posses and initial strength to meet biomechanical demands ~ Degrades in a predictable manner over time ~ Undergoes complete absorption without harm to surrounding tissues
41
INTERNAL FIXATION CONTINUED. ..
General Screw Fixation Technique: ~ Place one screw perpendicular to the fracture / osteotomy line for maximal compression. Place the 2nd screw perpendicular to the longitudinal axis of the bone this provides greatest resistance to the axial loading forces on the bone.
~ If only a single screw placement is allowed - place the screw in an angle that is halfway between the angle that is perpendicular to the fracture line and perpendicular to the long axis of the bone

INTERNAL FIXATION CONTINUED
General Screw Fixation Technique Continued: Load Screw Technique • This technique is commonly used in plate fixation. • Involves placement of 2 screws in the plate that is closest to the
fracture line to be drilled offset away from the fracture line. • As the screws are advanced the bone segments between the two screws
are further compressed.
Lag Screw Technique • Placement of the screw so that ONLY the thread engages the distal
cortex of the bone. • Thus further advancement of the screw results in approximation and
subsequent interfragmentary compression. • Most effective in fracture / osteotomy that is 2x's the width of the
bone or has a fracture angle that is less than 40°.
Partially Threaded Screw Insertion Technique 1. Thread / Pilot Hole 2. Countersink (increases surface contact between screw head and the bone) 3. Depth gauge (measures distance between the proximal and distal cortex) 4. Tap 5. Insert Screw
Fully Threaded Screw Insertion Technique 1. Thread / Pilot Hole 2. Countersink 3. Glide Hole 4. Depth gauge 5. Tap 6. Insert Screw

INTERNAL FIXATION CONTINUED. ..
Soft Tissue Anchors: S Used for reattachment of tendons or ligaments •S 2 basic types: Expandable / Screw type S Complications: Improper Placement / Failure of Suture / Pullout
Plates: S Various size and shape - allow alignment of the bones and stability
across the fracture / osteotomy site •S Stability allows for early passive RoM •S Adequate screw fixation is important for the plate to function properly •S Plate designs include semitubular, 1/3 tubular, Vi tubular, T - plate, L
- plate, calcaneal plate...
Types of Plates: 1. Neutralization Plate
a. Prevents torsional / bending forces from acting on the lag screws
b. The ridge extension of the plate on the bone proximal & distal to the fracture / osteotomy site helps neutralize any extra forces along the bone segment
2. Compression Plate a. Generate compressive forces along the fracture / osteotomy site
by either placing the plate on the tension side of the bone, off-set drilling (AKA load screw technique) or pre-bending the plate.
45
INTERNAL FIXATION CONTINUED. . .
Plates Continued...
3. Dynamic Compression Plate (DCP) a. Employs the concepts of offset drilling with unique plate
designs to optimize the compressive forces of the plate b. Disadvantage is it increases periosteal damage and decrease
intramedullary blood supply to the area, decreasing the overall strength of the bone segment
4. Limited Contact Dynamic Compression Plate a. Has a series of recessed undercuts on the undersurface of the
plate which allows limited contact between the bone and the plate
b. Generates less disruption to the vascular supply
5. Buttress Plate a. Anchored to the main stable fragment b. Supports the load-bearing bone c. Indicated in impacted fracture that results in comminution (e.g.
tibial plateau and the tibial pilon fractures)
6. Bridge Plate a. Useful in unstable comminuted fractures by spanning the
length of the comminution b. Frequently used with bone grafts to fill the voids in the bone
46
EXTERNAL FIXATION External fixation implements the use of wires, pins, and rods to keep bone segments in alignment or compression. Furthermore they allow distraction of bone segments by the principle of tension-stress effect.
Advantages: > Use in open fractures, acute, fractures, infected fractures and non-
unions > Requires minimal tissue dissection > Allows compression, neutralization, or fixed distraction of bone
segments > Length can be maintained in a comminuted fracture > Allows access to the wound site for care, monitoring and dressing
changes
> Full weight bearing is allowed immediately post-operatively
Disadvantages: > Requires skin and pin tract care > Difficult frame construction > Bulky frame > Fracture through the bone is possible > Refracture possible after frame removal > Expensive Basic Principles of External Fixation: 1. Frame should avoid and respect all vital structures in the area 2. Allow access to the wound site 3. Frame must meet the mechanical demand of the patient and injury
47
EXTERNAL FIXATION CONTINUED. . .
Complications: S Pin irritation - avoid pin placement in muscle •S Pin tract infection - most common complication (30%) •S Neurovasculature Impalement - Anterior Tibial A. & Deep Fibular N.
and they are most commonly involved •S Delayed Union / Non-Union - due to faulty frame construction •S Compartment Syndrome - due to increase in the intracompartmental
pressures (mmHg) •f Refracture - once the frame has been removed due to tension
shielding, a rare complication
Types of External Fixators:
1. Unilateral Fixators S Produces compressive or distraction forces S Used to fixate fractures, fuse joints, and lengthen •S Available in small or large, it is attached to the bone by multiple
half-pins screwed into the bone and attached to the fixator with the clamp
•S Main disadvantage - not create any sagital plane stability & therefore should not weight bear immediately post-op
48
EXTERNAL FIXATION CONTINUED
Types of External Fixators Continued...
2. Circulator Fixators •S Produces compressive and distraction forces •S Used to fixate fractures, treat non-unions, limb-lengthening , soft
tissue lengthening, and correction of congenital deformities. •S Utilizes trans-osseous wires with half-pins to position the wires in
different plane stability S Limited by the circular frame's ability to fit the extremity and
patient's comfort of wearing the apparatus
3. Hybrid Fixators S Combination of unilateral and the circular fixator S Used to treat tibial plafond fractures and pi Ion fractures S Utilizes trans-osseous wires and half-pins and footplate to allow
early weight bearing
4. Taylor Spatial Frame Fixators •S Newest external fixation device •S Allows for reduction and stabilization of fracture S Its unique feature allows for reduction of complex triplane
deformities
49
EXTERNAL FIXATION CONTINUED. . .
Dynamization: After removal of the plate, the bone may be prone to re-fracture during weight-bearing because of weakening of the bone from disuse osteopenia. To prevent this complication it is important to gradually release tension in the trans-osseous wires and loosen the pins to allow the bone to gradually strengthen as it bears weight.
Fixator Care & Management: Pin sites need to be kept clean with sterile solution and applied antibiotic cream in order to prevent infection and seal the opening around the pins. Avoid applying Betadine around the pins in order to avoid corrosion.
