Can Liposuction Fix a Glute Injury from a Fall?

I had a nasty fall while rollerblading a few years ago and fell quite hard on my butt. A deep bruise appeared and swelling ocurred right away. After about a month, I noticed that a pretty large bump (approx.1" wide x 2" long) wasn't going away, but had/have no pain. I consulted a doctor who thought it may just be a very deep hematoma and suggested I return if it didn't get any better after a 3-6 months. After 6 months, I consulted a plastic surgeon and had an ultrasound done. No liquid was detected in or behind the bulge. His theory was that I had broken the sheet around the muscle, and that it was the muscle bulging out. He said he could try to "fix" it, but it may leave an indent instead and look worse than it already does. I then went for a second opinion and was told by another plastic surgeon that he may be able to "fix" it with Liposuction. Howevern, he didn't order an MRI or CT. We already know there is no liquid involved, but it could be an air pocket, muscle, or scar tissue. Can Lipo help resolve this?
