The MIS Precision Chevron Bunion System™ is a kit designed to allow surgeons to perform a chevron bunion osteotomy, and subsequent fixation of the osteotomy, with a minimally invasive surgical technique. The MIS Precision Chevron Bunion System™ consists of a single, sterile-packaged SKU that contains both implants and instruments needed for the procedure.The implants in the kit are cannulated headless compression screws, made from titanium (Ti-6AL-4V ELI). There are two implants in the kit, however only one is used in a surgical procedure. Two implants are provided to allow the physician to select the proper size for the patient at the time of surgery. The implants are 3.5 mm diameter, with lengths of 24 mm and 27 mm.There are also single-use instruments, made of injection molded polycarbonate, PEEK, and stainless steel included in the MIS Precision Chevron Bunion System™. Instruments include an osteotomy guide (one each for left and right feet), a targeting guide, a screw guide, screwdriver, drill bit, and several K-wires and a guidewire.Additional general surgical instrumentation is utilized, but not part of the RELJA system, such as sagittal saw, drivers, and scalpel.
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.
