Corpse Girl fixing a broken leg and fingers

She limped over to St. George. He tore the other railing off, let it clatter on the deck, and lifted her out of the wreckage of the gangplank.
Her left leg twisted at the knee. Her foot pointed almost straight to the left. “You okay?”
“I don’t think anything’s broken,” she said.
…
She tugged on the fingers of her left hand. Each one popped back into place. “Hey,” she said, shaking the hand loose, “can you stand on my foot?” She swung her hips and put the twisted leg in front of him.
…
The Corpse Girl wrenched her hips back, and the leg cracked three times. She yelped. St. George yanked his foot away and she stumbled. “Okay,” she said, “that tingled a little more than I thought it would.” She rubbed her stomach, then took a few cautious steps. “Don’t think I tore anything, though.”
