Flashcards in Coaptation (Lewis) Deck (23):
1

Coaptation

Definition

  • To approximate
  • Extra-corporeal tx modalities for musculoskeletal abnormalities
  • Examples
    • casts
    • splints
    • slings
    • bandages

2

Fracture reduction

Toggeling

  • approximate to optimize healing
    • closed reduction I guess....
  • approximate to restore normal function
    • functional after alignment
  • minimize additional trauma

3

Splints (coaptation) counteract what forces?

Bending

 

4

Coaptation indications

  • temporary immobilization of musculoskeletal injuries
  • Fractures
    • younger animals
    • distal extremities
    • simple/stable fractures
  • ligament and tendon injuries

5

Coaptation:

Basic principle

  • Prolonged coaptation contraindicated following open reduction and internal fixation
    • will not increases stability
    • promotes fracture dz

6

Coaptation: types

  • Schanz soft padded bandage
    • nothing rigid
    • dec. seroma formation
  • lateral coaptation splints
  • full and half cylinder casts

7

Coaptation: application

  • Genearlly requires sedation or anesthesia
  • radiograph limb following application
    • and probably post lux too
  • take two orthogonal view radiographs
  • include joint proximal and distal to injury

8

pre-formed splints

pad depression

9

malleable splints

pad protuberances

10

Digits

  • Always leave digits exposed
    • or get a lawyer

11

Lateral splint

  • ie: tongue depressors
  • put in functional position
    • normal standing angles
  • Cling goes on snug

12

Splint materials

  • Yacca board
  • Aluminum splint rod
  • Thermoplastics
  • Fiberglass/resin, other synthetic cast material
  • Plaster of Paris
    • large animal only...?

13

Coaptation: Cardinal rule

Test question

  • immobilize joint proximal and distal to injury
  • coaptation device usually extends to digits

14

Spica Splint or cast

  • Coaptation which extends proximally over midline
  • Used for injuries proximal to elbow or stifle
    • elbow lux
    • humoral fx
    • some shoulder injuries
    • scalpal fx

15

Robert Jones bandage

  • Temporary immobilization
  • prevent swelling and further displacement
  • injuries distal to humeral condyle
  • injuries distal to femoral condyles

*big bulkly cotton stuffs, and used in Large animal

16

Mason-Meta Splint

  • Pre-formed or self fashioned spoon splints
  • injuries distal to carpus and hock
    • don't use for radius/ulna fracture

17

Don't pin the ....

radius

18

Velpeau sling

  • Prevents weight bearing
  • used for
    • scapular fractures
    • some shoulder injuries
  • no hard materials, just soft stuff

19

Figure-of-eight sling

  • prevents weight bearing
  • Used following coxofemoral luxations
  • Flexes, abducts and internally rotates hip

20

Most hip luxations go

craniodorsal

21

Ehmer sling

  • like figure-of-eight but wraps around dogs waist
  • maintains flexion, abduction and internal rotation

22

90/90 flexion bandage

  • non-weight bearing sling
  • stifle and hock maintained at 90 degress
  • used to prevent 'quadriceps tie-down'
    • maintains quadriceps mechanism in extension
  • Usually only keep on for a couple days
  • form of physical therapy

23

When using closed reduction we don't always get

anatomic alignment

-does need to have functional alignment tho
