When Kelly Anderson shed her arm cast two months after a wrist operation, her joints were so stiff she couldn't turn a doorknob. She didn't fully recover for another four months. Daniel Amante suffered similar post-cast complications after he injured his knee; Amanda Harton watched her soccer teammates struggle following various injuries; and Clara Tran saw even greater suffering among the frail patients in the nursing home where she volunteered.
Doctors in Scotland are using ultrasound to help patients with severe bone fractures, and finding it speeds recovery time by more than one-third. The ultrasonic pulses induce cell vibration, which doctors say stimulates bone regeneration and healing.
A maned wolf that had been left for dead after being hit by a truck was released back into the Brazilian wild this month, granted a speedy recovery through the use of stem cells. The female wolf is reportedly the first wild animal treated with stem-cell therapy, according to the Brazilian National Journal.
Creating an adhesive that can bond together bones has long presented researchers with some sticky problems. Many glues will not adhere to slick, wet surfaces, and those that do still tend to dissolve into the surrounding liquid. When setting shattered bones, surgeons instead must turn to metal screws and plates, a less-than-optimal process that often involves multiple surgeries and the lasting effects of metal implements inside the body. But researchers in Utah may have found the key to creating bone-setting glue, in a tiny, sandcastle-building aquatic worm.

"Leech" is derived from an old English word meaning "physician," and in the practice of Dr. Gregory Hartig, based in Madison, Wisconsin, that makes sense. After performing a reconstructive surgery, Hartig still sometimes prescribes leeches. From prehistory to the present, the bloodsucking worms have been applied to treat everything from cancer to broken bones. Modern research has shown that leeches help blood circulate and prevent clots. The problem, according to Hartig, is that many patients don't like the idea of carnivorous parasites biting into their flesh and slurping down their blood.
