I also did the turn-out and wait after our initial rehab process.
Mine did a foreleg, and we did PRP, shockwave, then laser 2x/week for 6 weeks. (I LOVE laser for injuries. It cost me $75/session. So I could at least spread out the cost, and we would do one farm call/one I brought her in each week)
I think the rehab depends on the horse as far as turnout/under saddle walking. For mine it was 30-days complete stall rest, then hand-walking. This could be pretty explosive, so used drugs and then began incorporating the turnout in a roundpen, under supervision. (I just feel like once you’re on their backs, you may be inclined to push them)
Then, I sent her home to be bred, “try to be bred,” which was the best medicine. She came back into work in September after I failed 3x…
I want to say she was injured beginning of March '22, I did the rehab process of shockwave, then laser, handwalking. I would have sent her home to be chucked out in a field June '22? She sat in a pasture until September when I brought her back into work. A month of hacking, then slowly adding trot work, canter. We ran our first event back January '23.
I will add, end of October I had my vet evaluate her. She flexed and jogged sound on the intial injured fore, but flexed a touch off on the opposite fore. We scanned it and found some minor inflammation. We assume for compensating on the opposite fore. I did laser and rest on the opposite leg for a month. Then we resumed work. So, I would be wary of the pressure added when coming back from an injury and how a horse may compensate.
