Thank you all for your support & advice. I operated again on Skipper's hock this afternoon. Right now she's in the hospital pen, thumbing through the Yellow Pages looking for a good malpractice attorney to hire on her behalf.
I first set her in a bucket with about 6" of Epsom salt solution. She spent about 10 minutes standing in that bucket, in the bathtub with the lights off & the curtain closed so she wouldn't try to hop out. Then I laid her on the operating table & began the procedure.
One weird thing is that the skin on her hock was bluish-green in places. ???
??? I'm sorry I don't have photos to post. It didn't look infected or gangrenous, just a few pretty patches of blue-green on her pink leg. I wonder if it was from a reaction with the antibiotic ointment & the epsom salts. Or maybe it was bruising from all the previous treatment.
I used a utility knife blade this time, tried to make a good deep -- but not too deep -- cut into the swollen part of the hock. Again, there was just blood oozing out. I had a plastic pan of epsom salt solution on the table & held her cut leg in it, trying to wash out the infected matter. I did feel some squashy matter in there, but it was difficult to remove. I tried to pick it out with the hypodermic needle, tried to cut it out with the blade, tried to pinch it out with my fingers. I had very little success removing anything of substance.
I worked for about 15-20 minutes, poor Skipper was awfully patient. She barely squawked or fussed. I did have her wrapped up in a soft T-shirt and talked soothingly to her the whole time. It seems I may have helped to reduce the swelling but I really didn't think I got much out of her joint. I squeezed a huge glob of antibiotic ointment in the wound, and wrapped it with self-stick gauze.
She was able to stand on both feet afterwards. Probably trying to figure out which foot to use to kick my butt. Right now she's sitting down on the perch in the hospital pen. I plan to cook a special breakfast for her tomorrow morning, scrambled egg with spinach & corn.
Please keep Skipper in your prayers for a miraculous healing!
She doesn't want to have to endure any more of my amatuer surgical procedures!
