Severe comminuted fractures of the radial tuberosity used to be treated mostly by radial tuberosity resection, radial tuberosity replacement is accepted by patients of most ministries due to its high price, and many problems may occur after radial tuberosity resection such as instability of the elbow joint, displacement of the radius to the proximal end, affecting the stability of the lower ulnar radial joint, and many other problems, and patients with elbow dislocation and lateral collateral ligament injury, radial tuberosity resection is a contraindication, and the current opinion of scholars The current opinion of scholars is in favor of reconstructive fixation of the radial tuberosity, but for severely comminuted radial tuberosity fractures, it is often difficult to reconstruct due to the limitation of the surgical incision space, foreign scholars Thomas P Ruedi et al. published an article on severe comminuted fractures of the radial tuberosity – on-table reconstruction technique in Injury in 2010, proposing to remove the comminuted radial tuberosity fracture block out of the body, put together and reposition it. The on-table reconstruction technique is proposed to remove the fractured radial tuberosity from the body, reassemble it, restore the joint surface and fix it precisely, and then reinsert it into the body. Our case: One week postoperative function.
