Local bone denervation by MR–guided focused ultrasound has been demonstrated as a promising tool for pain palliation of bone metastases. A study in BMC Musculoskelet Disord 2013;14(267) has shown the safety and efficacy of MR–guided focused ultrasound treatment in osteoarthritis. Significant increase of pressure pain thresholds on treated area showed successful denervation effect on the nociceptive nerve terminals. MR–guided focused ultrasound is a promising and innovative procedure for noninvasive pain management of knee OA.

Blood-sucking leeches – used for thousands of years in Ayurvedic medicine – also approved by US FDA are a tool for healing skin grafts or restoring circulation,.

Doctors have used these small aquatic worms for several thousand years in the belief that bloodletting helps to cure a wide range of complaints from headaches to gout. They reached their height of medicinal use in the mid-1800s.

Today, doctors around the world use leeches to remove blood pooled under skin grafts for burn patients or to restore circulation in blocked veins by removing pooled blood. Leeches are particularly useful in surgeries to reattach body parts such as fingers or ears. The leeches can help restore blood flow to reconnected veins.

FDA has approved leeches as a medical device. When leeches begin feeding, they inject salivary components (e.g., hirudin) that inhibit both platelet aggregation and the coagulation cascade. This results in a marked relief of venous congestion. The anti-coagulant causes the bite to ooze for up to 48 hours following detachment, further relieving venous congestion. By feeding for 10 to 60 minutes, leeches consume from 1 to 2 teaspoons of blood. Results from clinical studies showed that the success rate of salvaging tissue with medicinal leech therapy is 70 to 80%.

Indications

  • Poor venous drainage (venous congestion/venous outflow obstruction); or
  • Salvage of vascularly compromised flaps (muscle, skin, and fat tissue surgically removed from one part of body to another).
  • Salvage of vascularly compromised replants (limbs or other body parts re-attached after traumatic amputation).
  • Knee osteoarthritis, inadequate arterial supply or tissue ischemia, and for all other indications.
