My OTTB mare had a mishap with a t post and ended up with a 6in puncture in her hamstring muscle group yesterday. 
Per the visit notes from my vet:
“Deep puncture wound on the medial aspect of the mid-body Semimembranosus muscle. The would goes full thickness through the muscle belly and then travels proximally both subcutaneously and between muscles… Two edges of the muscle are endematous and protruding from the wound.”
The pieces of muscle that are protruding were not trimmed back as we’re hoping they will recede back into the wound once the swelling goes down, and the attending vet did not want to cause more muscle damage to the area by removing them. Of course, if the tissue starts to die off they will be removed.
Since I’m dealing with a hamstring injury, I’m especially worried about fibrotic myopathy and losing some of her range of motion with that hind leg. I already have some asymmetry issues with that right side as she suffered a pelvis fracture at some point (long since healed) and her pelvis is narrower on the right vs the left.
Are there any treatments that help minimize scar tissue formation?
She’s currently in a small paddock off the barn to allow easy access for my vet to give IV antibiotics (3 days worth). Thursday she will be back out on pasture and I had been instructed once she was feeling a little better that light riding was encouraged to help keep her moving. I brought up doing forward stretches with the RH, which was also encouraged.
Vet did not offer much regarding preventive measures and I have not had the chance to ask. However, she did mention possible option (didn’t specify) if I started noticing changes in her gait (which would indicate the start of scar tissue formation).
Honey was also suggested for the wound. Would this help with scar tissue? Suggestion on types/brands? Is Manuka worth it, or would a local raw option be just as good?
