Titanium alloy Newdeal sterile angular locking system fixation consists of variable angle screws and washers. This system is available in different sizes. The osteosynthesis screws are fixed to the bone through the plate holes, creating a single implant/screw unit. The system is locked by means of washers drilled into the threaded lipped sockets at the top of each hole, thus blocking each screw head.
"A small, sterile, threaded rod with a slotted head typically used for internal orthopaedic fracture fixation by being screwed into bone to hold plates or nails to bone or to provide direct interfragmentary stabilization of bone, or it may fasten soft tissue to bone; it is made of a material that cannot be chemically degraded or absorbed via natural body processes (includes implant grade metal such as surgical steel, titanium alloy, or carbon fibre). There are a number of kinds available: cortical, cancellous, malleolar, scaphoid, partially-threaded and fully-threaded, self-tapping, and cannulated. A ""lag screw"" can be any of these used to obtain compression across bone fragments."
