Sizes: 0.7-1.6mm Often placed percutaneously Uses: Used in skeletal fixation of bone fractures Used for skeletal traction for bone fractures Often used on small bones such as phalanges, wrist, and ankle Smooth Steinman pins/smooth pins Features: Smooth stainless-steel pin with a trocar diamond point Sizes: 2.0-4.8mm Often used on larger bones Uses: Used for fixation of bone fractures and bone reconstruction To guide while placing implants and placing skeletal traction Threaded Steinman pins/threaded pins Features: Threaded stainless steel pins with a trocar or diamond point Sizes: 2.0-4.8mm Uses: Used for fixation of bone fractures and bone reconstruction To guide while placing implants and placing skeletal traction Cannulated pin cutter Features: Heavy, curved handles with extremely curved jaws and sharp edges. Circular pin channel between the jaws – allow the pin to slide through the jaw so the proper length can be cut. Uses: To cut wire or small pins such as K wires or Steinmann pins. Diamond pin cutter Features: Heavy, curved handles with a guillotine-action tip. The working end has an angled channel allowing the pin to be placed into the jaw so the proper length can be cut. Uses: To cut wire or small pins such as K wires or Steinmann pins Large pin cutter/bolt cutter/rod cutter Features: Very long handles with double action hinges and a sharp, small cutting surface. Uses: To cut heavy pins and rods. Mallet hammer Features: A solid or brass-filled stainless-steel hammer-like instrument Weight – 1 to 3 pounds Uses: To impact and extract implants or exert force on osteotomes, chisels, gouges, tamps and other specially designed instruments Lamina spreader Features: It has teeth which allow for a secure grip on the tissue. Gentile curved profile to allow optimal access to the surgeon. Flat or concave blades Uses: To aid in widening the space between the lamina To hold the disc spaces open Pedicle probe Features: Straight with ball tipped Uses: To sound the pedicle for any cortical breach in all four quadrants To confirm whether there is any penetration to vertebral body anteriorly during pedicle screw fixation Bone tamp/tamp Features: Solid stainless-steel dowel with a grip handle The working end is round and flattened Uses: To compact or wedge a structure into place Townley caliper Features: A slide ruler Measures in mm and inches between the tips Uses: To measure the thickness of patella before cutting its undersurface during a total knee arthroplasty Bone cement gun Features: The proximal end has a plunger-type disk that moves forward when the handles are compressed. This forces the glue through the chamber and out the tip. Uses: To inject polymethyl methacrylate (PMMA) bone cement during total joint procedures Bone cement system Features: The liquid monomer Is highly flammable. Uses: To produce bone cement by mixing the liquid (monomer) and powder (polymer) Chuck and key/drill chuck Features: A specialized type of clamp in which the jaws, which are placed radially in symmetrical pattern, are used to hold a cylindrical object. The jaws will be tightened or loosened with the help of a chuck key. Uses: To hold rotating devices such as the drill bit or a pin in a power tool Universal screwdriver set/screwdriver kit Features: It consists of a handle accommodating the double-ended screwdriver bits and one each of small and large single slot, cross and cruciate, 3.5mm and 4.5mm hex, and small and large Phillips heads. Uses: Used during revision of total joint surgery in which screws were used. Used during removal of bone plates, fracture fixation screws, or bone graft screws. Plate bending pliers/plate bender Features: The plate is slid into the jaws and compressed to bend the plate. Available in various sizes and designs Uses: To bend the plate to conform to the contour of the bone in which it is being implanted during open reduction internal fixation Lead hand Features: A hand-shaped malleable metal device with tabs Uses: To position the hand open for exposure during hand procedures. Gigli saw Features: A flexible, twisted wire cable with looped ends affixing to the hooks on the “T” handles. The handles may also be oval or box shaped. Do not run fingers and/or hand along the blade; this could tear gloves and skin. Uses: To cut bone. Often used for amputations. Can be used to open the skull for craniotomies. Stryker system 6 power Features: All-in-one battery-powered system consisting of a number of heavy-duty drills and saws, with a variety of attachment and chucks that are used for a specific purpose. Uses: To cut, ream or drill large bones. Depth gauge/screw depth gauge Features: A thin, stainless-steel probe with a right-angled hook on the distal end The measuring device is solid and flattened, which Is calibrated in mm on the proximal end. There is a sliding metal sleeve encircling the probe and measuring device. Uses: To confirm the depth of the drill hole in bone to determine the length of the screw Duckbill right and left biter Features: A thick handle with thumb lever which opens and closes the jaws It has a square-shaped cutting tool on the right or left side of the instrument. Uses: To confirm the depth of the drill hole in bone to determine the length of the screw. PULSAVAC/pulse lavage Features: It comes with a battery pack which provides power. The irrigation spike and the suction connection are handed off the sterile field. Uses: Used for irrigation and debridement of tissues. Commonly used for high-pressure irrigation during total joint arthroplasties. Arthroscope Features: A rigid, stainless steel tube containing an optical chain of precisely aligned glass lenses and spacers. The objective lens is located at the distal tip of the scope. The stainless-steel cylinder is called the optical element or the telescope, providing both images and light. Proximal end: eyepiece or ocular lens attaching to the camera coupler. Uses: To view the inside of a joint. Thomas splint Features: Ring at an angle of 120 degrees Two side bars Outer bar bent to accommodate the greater trochanter. Leg supported on slings tied to the sidebars. Uses: To immobilize hip and thigh for injuries. To transport patients with lower limb injuries.
