Outcomes of Primary Volar Locking Plate Fixation of Open Distal Radius Fractures

초록

Background: Few studies have reported the outcomes of primary volar locking plate fixation in Gustilo and Anderson type II and IIIA open distal radius fractures. We report the outcomes of treatment of Gustilo and Anderson type II and IIIA open distal radius fractures using primary volar locking plate fixation. Methods: We retrospectively reviewed 24 patients with open distal radius fractures who were treated using primary volar locking plate fixation. The range of motion (ROM) and modified Mayo wrist scores were measured to assess functional outcomes. Radiological outcomes included the bone union period, radial inclination, volar tilt, radial length and ulnar variance. Results: Functional outcomes, including mean ROM in flexion (39.1 degrees) and extension (52.5 degrees), improved following primary volar locking plate treatment. Radiological outcomes were as follows. Mean bone union period, radial length and ulnar variance were 7.8 months, 10.4 and 0.7 mm, respectively. Two patients had superficial wound infection 2 weeks after surgery and one patient had non-union of the radius that required implant removal, autologous iliac crest bone graft and plate re-fixation. Conclusions: Primary volar locking plate fixation is a safe and reliable treatment option for Gustilo and Anderson type II and IIIA open distal radius fractures. By providing firm stabilisation and allowing early ROM exercise, primary volar locking plate fixation resulted in good functional and radiological outcomes.
