Orthopedic Surgery Flashcards
List the 5 stages of normal bone healing
Inflammation Cellular proliferation Callus formation Ossification Remodeling
List the two types of casting material
Plaster
Heavier; can accommodate some swelling
Fiberglass
Lighter; not so flexible
Why must Webril or stockinette be placed under a cast?
Protect skin from•Thermal injury as cast sets up
Abrasion/pressure when wearing cast
List 3 types of traction.
Manual
Use hands intra-op to reduce fracture
Skin (AKA: Buck’s traction)
Temporary for hip fracture in ER until patient is cleared for surgery
Skeletal
Done in OR to stabilize fracture for closed femoral rodding; used with OR fracture bed
Antibiotics
Prevent SSI or to treat existing infections
Hemostatics
Reduce bone bleeding
Steroids
Reduce post-op inflammation, swelling
basic bone physiology:
Support, movement
Mineral storage
Formation of blood cells (hematopoiesis)
Flexion
Extension
Internal rotation
External rotation
Act of bending or being bent, decreasing the angle at a joint
Moving parts of a limb into a straight position, increasing the angle at a joint
rotate a limb medially
rotate a limb laterally
Define Knee Arthroscopy
Visual exam of the knee joint
Surgical Anatomy of Knee Arthroscopy:
Bones and bone features
Ligaments
Soft tissues
Bones and bone features: Femur Femoral condyles Tibia Tibial plateau Patella Ligaments Anterior cruciate ligament (ACL) Posterior cruciate ligament (PCL) Medial (tibial) collateral ligament (MCL) Lateral (fibular) collateral ligament (LCL) Soft tissues Joint capsule Synovium Suprapatellar pouch Patellar tendon Articular cartilage Menisci; medial (1) and lateral (2)
Physiology of Knee Arthroscopy
Support and movement
Pathophysiology/indication for Knee Arthroscopy
Torn meniscus
Loose bodies
Worn patella
Torn ACL
Procedure steps summary for Knee Arthroscopy
A tiny incision is made for inflow cannula is made using #11 blade; distend joint with fluid
Another incision is made for sheath; sharp trocar using #11 blade; change to blunt trocar then place arthroscope and camera
Determine the incision site by inserting a spinal needle Make another incision using #11 blade and insert probe for EUA
Treat PRN (provide an example)
Shave away meniscus, cartilage, or patella
Repair meniscus or remove loose body
Remove instruments, arthroscope and trocars
Irrigate, close, dress (FYI: inject for post-op pain control)
Define Shoulder Arthroscopy
Visual exam of shoulder joint
Surgical Anatomy for Shoulder Arthroscopy:
Bones and bone features
Joints
Muscles
Bones and bone features: Clavicle Acromion process Scapula Coracoid process Glenoid fossa (cavity) Glenoid labrum (ligament ring surrounding articular cartilage) Humerus (Humeral head) Joints Glenohumeral and acromioclavicular Muscles (rotator cuff) Supraspinatus and Infraspinatus Teres minor and Subscapularis
Physiology of Shoulder Arthroscopy
movement
Pathophysiology/Indication for Shoulder Arthroscopy
Torn glenoid labrum
Torn rotator cuff
Impingement syndrome
Procedure Steps Summary for Shoulder Arthroscopy
Distend joint with fluid via syringe and spinal needle
Inject local
The spinal needle is removed and an incision is made over the joint capsule using #11 blade
Insert the sheath and sharp trocar into the incision
Change into a blunt obturator and insert scope/camera/with inflow cannula
Additional Incisions is made for the other port sites; insert instruments PRN;
The bicep tendon is identified and examined
The bicep tendon is used as a landmark throughout the procedure.
Treat PRN*
Bankart
(Done for recurrent anterior dislocations; repair torn labrum)
Reattach labrum to glenoid with bone anchors
Rotator cuff repair
Insert anchors; and secure sutures to repair tear
Acromioplasty
(done to correct impingement syndrome; often done in conjunction with other repairs)
Use burr to trim portion of acromion
Change ports w/switching stick PRN
I and remove any loose bodies/Additional local may be inject for post-op pain control/C/D
Define Acromioplasty
Surgical repair of the acromion
Define Bankart
Aprocedure used to correct recurrent anterior shoulder dislocation
Define ORIF radius
Open Reduction and Internal Fixation of the radius
Procedure summary ORIF radius
I/H/D until the fracture is exposed/R; EXPOSE FRACTURE
Reduce fracture with self-retaining bone reduction forceps
Malleable plates are placed against the bone and contoured to the radius using a plate benders
The plate is placed on the bone and held in place with a self-retaining bone holding forceps
The first hole is made using a drill and drill guide.
Depth gauge is used to determine the size of the screw
The screw is selected and placed on the bone
Fixate fracture by applying plat and screw
The wound is thoroughly irrigated
The tourniquet is released
Hemostasis is achieved PRN using ESU
The incision is closed and dressings are applied
Procedure summary for ORIF hip fracture
I/H/D until the fracture is exposed/R: expose fracture
Place guide pin into femoral head with guide angle
Determine the reaming and tapping depth and screw length
Assemble the appropriate triple reamer and place it on the power drill
The reamer is placed over the guide pin and drilled into the femoral head
Assemble the lag screw insertion together and place it over the guide pin to insert the lag screw
The wrench, guide shaft, and guide pin are removed
The plate is seated using an impactor and mallet
Fixate the plate against the femur using screws
The wound is thoroughly irrigated
Hemostasis is achieved PRN using ESU
The incision is closed and dressings are applied (xeroform, 4x4 gauze, and ABD pad)
