Case 224
Hock & Cannon
Area Injury
This is a Team Penning Quarter Horse Gelding with two injuries on the left rear leg. The inside injury is at
and above hock level, the outside injury is mid-cannon. These injuries were caused by getting caught in the
loop of a power pole guy wire.
Day 1
Peppy arrived wrapped in a "Robert Jones" style bandage on the injured leg.

Day 3
There was exposed bone and severed
tendons at both major wound sites.

Treatments consisted of Wound
Wash and PRP Gel with occlusive
Day 6
The end of the severed
tendon at the cannon
wound site was removed.
Day 9
The granulation tissue is well started, PRP Gel is applied at the exposed bone
sites to help promote tissue growth.
Day 15
With the exception of where a small
portion of bone is still exposed, the
granulation tissue has reached skin
A new product, the "Tapeless
Bandage" was tested for viability.
Day 20
Peppy chewed on the cannon wound, and placental tissue was implemented
to aid in repairing the damaged tissue. The chewing presented a new
problem, as we now had to treat both mature and immature granulation
tissue in the same area. This presented a challenge in bandaging techniques.
Day 29
Due to Peppy's chewing
activities on the lower
wound, proud flesh
occurred in the damaged
area. CarraSorb was applied to the area of immature
granulation tissue to aid in controlling the overgrowth.
The wound on the inside of the hock continues to
mature and the epithelial border is growing well.
Day 36
The hock wound is doing very
well. The damaged tissue on
the cannon wound has
matured, and the overgrowth
has stopped. We are applying
"QuickDerm" to the overgrown
area to reduce the size of
Day 51
The hock wound continues to contract in size, and has a distinct
epithelial border. The cannon wound has begun to contract, and
the epithelial border has re-started at the chewing damaged area.
Day 59
The hock wound is healing beautifully, we expect very little scarring at this wound site.
On the cannon wound site, we have an interesting development. An island of epithelial tissue developed
independent of the border epithelial tissue. This is something we have seen only in pythiosis cases, or in
cases where tissue has been transplanted (hair plugs).
Day 68
The hock wound has contracted to
1/4 it's original size. The cannon
wound surface has smoothed and
contracted back to just above skin
level, and the island of epithelial
tissue continues to grow.
Day 82
The hock wound now has only
approximately 3/4 inch uncovered
granulation tissue remaining. The
cannon wound looks great, the island
of epithelial tissue has connected with
the border epithelial tissue.
Day 95
The hock wound continues to contract and the skin pigmentation
is returning to the original color. Picture 2 shows the cannon
wound with the paper towel in place. This is removed every other
day, taking the scab surface with it. The island of epithelial tissue
is now fully incorporated in the border epithelial tissue.
Day 106
The hock wound is now almost completely closed, there is just a small sliver of
open granulation tissue left. The skin continues to change back to the original
pigmentation, and the hair has started to grow back along the edges.
The cannon wound has also contracted a great deal, and the skin pigmentation
has started to revert to original color.
Day 120
The hock wound is closed, with only a pen tip wide, 3/4 inch long spot left to seal.
The open area of the cannon wound is now approximately the size of a silver
dollar, and continues to contract and heal.
Peppy went home on this day, and at last report, was being re-conditioned to
return to the roping arena.
