Forearm Fracture Fixation Using a 3.5 mm Titanium Locking Compression Plate 

Today, we'll be discussing the 3.5mm titanium locking compression plate system. The plates are available in both stainless steel and titanium options. These plates are 3.5mm thick, 12mm wide, and range in lengths from 70 to 278mm, which corresponds to a five hole plate all the way up to a 22 hole plate option. The plates are laser marked for number of holes on the plate for easy access and reading during surgery. There are also specific holes in the plate which accept K-wires for provisional fixation of fractures. The screw holes are able to accept both locking and non-locking screws. The plates are available in a small tray or can be placed in the ankle fracture or distal radius system. Instrumentation available within the system include an eccentric drill guide for compression plating and a French bending iron. We have approached this form fracture through a volar approach of Henry, isolating the fracture in the center of the of the wound. Retractors have been placed deep in an extra periosteal manner, so as to expose the fracture and allow for fracture reduction. Using these two lobster claw clamps, the fracture is reduced into an anatomic position after being happy with our reduction. We then place the plate in a provisional manner along the flat surface of the bone. Here we've centered the plate over the fracture site after obtaining provisional reduction of the fracture. In order to obtain a provisional plate fixation, we can use these K-wires holes within the plate. In order to obtain compression, screws must be placed on opposite sides of the fracture. Initially, we will place a screw in the center of the hole on the proximal segment of the fracture. The cortical screw which will be placed bicortical. The standard drill guide may also be used in the center of the hole. After drilling and measuring for appropriate depth, an appropriate size 3.5mm screw is placed in the hole. It is sometimes helpful to stabilize the plate against the bone using a lobster claw clamp in order to obtain maximum compression. An eccentric hole will be drilled in the plate. The eccentric drill guide is used, with the Arrow placing towards the fracture, so as to assure that the hole is drilled in the appropriate location. Similarly, a standard drill guide can be used to be assured that the drill hole will be placed eccentrically in the compression hole. Once again, the screw is measured for appropriate length, and the appropriate 3.5mm screw is placed in the hole. Prior to seating the screw. The fracture must be assessed for reduction in the K-wires in that segment must be removed. The fracture can be controlled with a bone reduction forceps so as to assure anatomic reduction. Once happy with the reduction, the screw can be advanced to engage the compression mechanism within the plate and to provide compression at the fracture site to. Supplement our fixation. Multiple screws are placed on both sides of the plate in a bicortical fashion. The option exists to either use locking or non-locking screws. In this regard, here we demonstrate use of the locking tower to place the locking screw in this screw hole. Depth can be read off the laser mark on the drill or by using the standard depth gauge. Another unique feature of this locking plate is that the locking screws sit countersunk within the plate. Finally. Here we have completed fixation of the fracture, obtaining six cortices of fixation above and below the fracture to provide maximal stability.
