A brace for treatment of distal radius fractures allows an adjustable range of motion while simultaneously providing for distal traction. The brace has hinges with adjustable stops, the hinges being made of radiolucent material to allow x-rays without the necessity of removing the brace. Adjustable tensioners are used to provide distal traction by way of a metacarpal pin placed in slots in hand members. The brace is adjustable for different size patients.

Embodiments of the present invention relate to a force sensing system and method for total knee arthroplasty. For example, a force sensing system includes a spacer block that is adapted to be positioned adjacent a resected distal femur and a resected proximal tibia. The spacer block is configured to receive a first force applied by the resected distal femur and a second force applied by the resected proximal tibia. The force sensing system also includes at least one sensor that is associated with the spacer block and that is adapted to measure one or more forces exerted on the spacer block. Moreover, the force sensing system includes a display that is adapted for displaying an indication of the one or more forces measured by the at least one sensor.

An intraosseous needle having a threaded shaft with a passageway extending substantially therethrough, a solid and pointed tip at one end thereof, the tip having a plurality of cutting edges which facilitate boring through a bone. The shaft also includes two side ports in communication with the passageway to allow fluids to pass through the needle into the interior of the Done after successful insertion thereof. There is a hub at the opposite end of the shaft, whereby the needle is adapted to couple with an appropriate gripping device. A handle is provided in the shape of a ball knob and is adapted to telescopically and grippingly receive the hub of the needle. The hub and handle are both equipped with mutually engaging torque-transmitting surfaces. Additionally, the threads of the intraosseous needle may optionally be tapered so that at least one thread at the proximal end of the threaded shaft has a greater major (and/or minor) diameter than at least one thread located at the distal end of the threaded shaft. As the needle is inserted, the tapering of the threads provides a tighter fit between the bone and the needle to prevent needle wobble and fluid leakage.
