Bone-knitter

A Bone-knitter was a piece of medical technology used to help repair damage to bones.

Bone-knitters worked much faster than traditional means of repairing broken bones, which were healed by immobilizing bones in splints so that they could heal naturally. 

Such knitters were used to help heal individuals who suffered broken bones in the wake of the Tarsus IV Massacre and resulting civil unrest. 

When a miniaturized Hikaru Sulu broke his leg, normal bone-knitting lasers were much too large to be used, so Doctor Leonard McCoy used a microscope laser instead. 

In 2365 the bone-knitters on the USS Enterprise (NCC-1701-D) stopped working due to an Iconian computer program running rampant through the ship's computer systems. Dr. Katherine Pulaski advised one of her assistants to use a splint instead.
