| What are the orthopedic indications for external coaptation? |
|
Definition
-limb immovilization: gractured bone, ligamentous instability
-support: preop, postop
-protection
-analgesia
-compression
-reduction and stabilization of a luxated joint |
|
|
Term
| What are the standard three layers of externa coaptation? |
|
Definition
-Primary layer: nonadherent dressing over a wound
-secondary layer (bulk): cast padding or rolled cotton
-tertiary layer: cling guaze
-/+ spline |
|
|
Term
| What is the purpose of the secondary (bulk) layer of external coaptation? |
|
Definition
-protect tissue
-relieves pain
-immobilize the limb |
|
|
Term
| What is the purpose of the tertiary layer? |
|
Definition
-compression
-immobilization
-protection |
|
|
Term
| What are the rules to live by in regards to external coaptation? |
|
Definition
-pick the appropriate bandage for hte desired infication
-do not wrap secondary and tertiary layers too tightly!! can cause circulatory compromise
-balance pressure and absorption
-manage the bandage appropriately
-MUST incorporate the joint above and below
-bandage msut allow for visualization of 3rd/4th digits distally |
|
|
Term
| What are the different types of bandages? |
|
Definition
-Robert Jones: most common
-Modified Robert Jones
-Spint bandage
-catsts
-Ehmer sling |
|
|
Term
| What are the functions of a Robert Jones Bandage? |
|
Definition
-temporary limb splintage: immobilization
-provides compression
-protects limb from vascular compromise
-pain relief: due to immobilization
-elimination of dead spece postoperatively: reduce swelling
-protect a wound that may also be present |
|
|
Term
| What is the one major drawback to the Robert Jones Bandage? |
|
Definition
| -can only be used on distal limb injuries!!! belowe the stifle or below the elbow |
|
|
Term
| What are the functions of the modified Robert Jones Bandage? |
|
Definition
-temporary immobilization: less than with splint
-allows for some compression
-adjunctive support post-op |
|
|
Term
| What are the three major technique differences in a MOdified Robert JOnes compared to a normal Robert Jones? |
|
Definition
-rolled cotton is NOT used
-primary layer is about 3-4 layers of cast padding
-limb is held at a standing angle |
|
|
Term
| What are the functions of a spoint bandage? |
|
Definition
-temporary immobilization: fractures, joint dislocations, postop support
-definitive care for moderately stable fractures if financially limited |
|
|
Term
| When do we pointedly avoid splint bandages? |
|
Definition
|
|
Term
| Do splint bandages provide compression? |
|
Definition
|
|
Term
| What are the three types of splint bandages? |
|
Definition
-standard: distal limb
-spica: proximal limb and extends to opposit hip/shoulder
-Schroeder-Thomas: outdated |
|
|
Term
| What are our options for malleable splint materials? |
|
Definition
-metal splint rods
-Schroeder-Thomas Splint
-thermoplastics
-padded metal
-cast tape
-felt covered cast tape |
|
|
Term
| What are our options for rigid cast material? |
|
Definition
| -Mason metasplint: metal or preformed plastic |
|
|
Term
| What are the downsides to using rigid splint materials? |
|
Definition
-cannot be molded, cut, or resized
-cannot conform to limb shape |
|
|
Term
| What is a common complication of rigid splint materials? |
|
Definition
|
|
Term
| What are the functions of a cast? |
|
Definition
-definitive stabilization of fractures
-resist bending and rotation forces
-does not counter axial forces-
-indirect bone healing |
|
|
Term
| What are the fracture criteria for cast use? |
|
Definition
-closed
0distal to elbow and stifle
-mechanically stable
-heal quickly |
|
|
Term
| What are the materials that we use in casts? |
|
Definition
-Tape stirrups
-Stockinette
-casting tape |
|
|
Term
| What do we look for when we evaluate a completed cast with rads? |
|
Definition
| -want 50% or more fracture reduction |
|
|
Term
|
Definition
-Caution with pressure points! sores are very common!
-weekly evals
-change if: wet, soiled, foul odor, sudden gait change, slips
-removal: bivalve, cast saw and spreader |
|
|
Term
| What is the purpose of an Ehmer sling? |
|
Definition
| -maintain reduction of a craniodorsal hip luxation |
|
|
Term
| How does an Ehmer sling work? |
|
Definition
| -it abducts and internally rotates the hip joint (forces the femur into the acetabulum) |
|
|
Term
| What materials do we need for an Ehmer sling? |
|
Definition
-Elasticon bandaging material
-clippers to shave hair |
|
|
Term
| When do we remove Ehmer slings? |
|
Definition
|
|
Term
| What is the purpose of a Velpeau sling? |
|
Definition
-stabilization of shoulder with medial dislocation
-support scapular fractures
-prevents weight-bearing on injured forelimb |
|
|
Term
| What are the complications of external coaptation? |
|
Definition
-bandage sores: monitor pressure points
-bandage slippage: places pressure in abnormal location and causes tissue necrosis
-fracture nonunion
-inappropriate placement: fulcrum created |
