Q
layers of digital pad
A
stratified epithemium
dermis
subcutaneous
5
Q
the outermost layer of digital pad is used for
A
Stratified epithelium
- Stratified corneum (thickest outer layer)
- wear/impact/friction
6
Q
the 2nd layer of digit
A
Dermis
- Forms papillary projections into the epithelium layer
- Aid in cushioning from ground reaction forces
- Eccrine glands
7
Q
the innermost layer of the digital pad
A
Subcutaneous layer
* Adipose
* Softest
* Distributes force
8
Q
healing challenges for foot injury
A
- Weight bearing
- Friction
- Shear
- Contamination
9
Q
keys to success for wound healing in paw pad
A
Preserve weight bearing surfaces
* Digital pads 3/4
* Metatarsal/metacarpal pads
* Digital pad 5
- Minimize tension and motion
- Protect from environmental contamination
- SET OWNER EXPECTATIONS
10
Q
repair options for paw pads
A
- Primary closure
- Secondary intention healing
- Local tissue flaps- Phalangeal fillet
- Free tissue graft: Paw pad grafts and Free skin grafts
- Amputation
- Prosthetics
11
Q
where can you not place free skin graft
A
- tendon/ligament/ bone- graft does not have its own blood supply
- infected, high motion areas
