Q

Describe each fracture healing
Fracture hematoma (72hours)
Granulation tissue (3-14days)
Callus formation (3rd week)
Ossification (3week-6months)
Consolidation ( 1 year )
Remodeling

A

When a fracture occurs, bleeding creates a hematoma around the end of the bone

Active phagocytosis absorbs the products of local necrosis
( new tissues & blood vessels )

Minerals and new bone matrix

New bone matrix will stop moving and we may remove the cast

Distance between bone fragments decrease and will close

Union is completed & callus is reabsorbed

29
Q

Ambulatory and home care cast
Do! (6)

Q

Ambulatory care
Cast care
Don’t!!!
(6)

Bear weight 48 hours
Cover cast with plastic

33
Q

What do we use to remove a cast?
Which does?

When the cast comes off what do we see?

A

Skin is pale
( under a wet band-aid)
Atrophy of muscle

35
Q

What can do we use for upper extremity immobilization?

A

Sling

36
Q

Slings helps encourage moments of ?
Also very careful on pressure around?
Do we use a sling on a cast?

A

Fingers and nonimmbomized joints ( shoulders )
Posterior neck
Because we don’t want the arm to hang up ( instead down) and provides
Traction ; correction of arm

37
Q

Notes
Upper extremity immbolization
Sling
- ensure axillary area is padded
- no undue pressure on neck
- encourage movement of fingers
- no sling use with long arm cast for upper humerus fracture - weight provided traction

A
