Abstract:[Objective] To introduce the surgical technique and preliminary clinical results of volar plate fixation of long segment comminuted Galeazzi's fractures without severing pronator quadratus. [Methods] From December 2018 to February 2022, 14 patients with long segment comminent type II Galeazzi's fracture were treated with abovesaid minimally invasive surgery. As an incision between the flexor carpi radialis and the radial artery was made 3.0 cm proximal to the transverse carpal line, the flexor carpi radialis was freed and retracted to the ulnar side, while the radial artery was retracted to the radialis side to reveal the pronator muscle. A periosteal stripper was attached beneath the pronator quadratus to peel off the muscle for establishing a "musculoskeletal tunnel”. A volarr locking plate in appropriate size was percutaneously inserted by three-point location. As fractures reduced properly, screws were placed respectively to fix the fractures. [Results] All patients successfully completed the operation with the average operation time of (75.1±15.0) min, and the average intraoperative blood loss of (38.2±30.3) ml. All of them were followed up for an average of (24.6±10.9) months, and the Mayo score was recorded 6 months after surgery as pain score of (23.6±2.3), satisfaction score of (23.9±2.1), range of motion score of (17.1±4.1), grip strength score of (23.6±3.5), and bone healing achieved in all patients. [Conclusion] The palmar plate fixation of long segment comminuted Galeazzi's fractures without severing pronator quadratus has advantages of less trauma, accurate internal fixation and rapid functional recovery of affected limb.
