Arthrex Radial Head Arthroplasty System

Speaker  The Arthrex radial head replacement system features a circular head paired with two stem options a smooth free floating design or a grip blasted press fit stem. Both Stem styles are supported by a single instrument tray, streamlining setup and emphasizing reproducibility and efficiency for the entire surgical team. The tray is organized into two layers for intuitive workflow. The first layer of the tray houses the side loading trial heads and stems and insertion tools. The bottom layer of the tray has the resection guides, Reamers Planers removal tools, sizing block, and the Specialty Shoehorn Distraction tool. The radial head can either be removed piecemeal or resected with the saw blade. A provisional cut can be made through the cutting guide, which also doubles as a head height gauge for efficiency. After the initial cut, the guide is removed. And the cut is completed. The excised head is removed and placed on the sizing block. Optimal head diameter is measured, focusing on not overstuffing the joint. The shoehorn distractor is positioned in line with the radial shaft to improve access for the preparation tools. Starting with the starter, all the surgeon advances until resistance is met. Laser markings on the awl indicate the starting diameter for reaming. The appropriate reamer is inserted by hand to the end of its flutes to minimize risk of fracture. The fluted section of reamer matches the length of the final stem implant. When using the planer, the curved end of the shoehorn distractor allows for full rotation of the planer without interference. The height gauge is reinserted to confirm head height. The trial stem inserter attaches to the selected Stem trial. Speaker  The Stem trial is intentionally shorter than the final implant for easier insertion and removal. After removing the stem inserter the head trial Inserter is attached to the trial head. The trial head is clicked onto the trial stem. The Inserter can either remain in place or be removed during fluoroscopy. Once head and stem sizing is confirmed, the surgeon selects either the smooth free floating or grip blasted stem. The free floating stem is slightly undersized to the reamers, while the press fit is line to line, the chosen stem is placed into the appropriate sizer on the sizing block, and the implant head is seated using the impactor and a mallet. Several controlled taps create the secure Morse taper connection. Note that there will be a small groove between the stem and the head. This aids in breaking the Morse taper. Should implant removal be necessary. The lobster claw from the instrument set provides traction during implant insertion. The monoblock implant is placed. And flora was taken to confirm fit and range of motion when removal is necessary. The Morse taper must be disengaged. Position the head removal tool in the groove between the stem and the head, and tap gently with the mallet to break the taper. The head can then be removed. The cannulated handle and threaded T handle are assembled and placed into the head of the stem. The T handle is rotated so the removal tool threads into the stem. The t handle serves as a surface to allow for back slapping with the mallet, or can be used to rotate side to side for controlled extraction.
