Abstract:
BACKGROUND:Distal radius C fractures belong to multiple fractures in the joint. Its treatment should recover various angles and joint surface continuity outside the joint. The recovery of palmar tilt angle, radial inclination angle and radial height is also very important for treating distal radius. OBJECTIVE:To study the changes in palmar tilt angle, radial inclination angle and radial height after type C fractures of the distal radius repaired with Acu-Loc(R)2 VDR bone plate system. METHODS:From May 2015 to March 2016, 11 cases of type C distal radial fractures were treated with Acu-Loc(R)2 VDR bone plate system. Preoperatively, the palmar tilt angle was-31° to-4° (-12.45° on average), and the radial inclination angle was 6° to 18° (11.18° on average), and the radial height was 1.92 mm to 8.68 mm (5.28 mm on average). X-ray films were observed at postoperative 4, 8 and 12 weeks and half a year in all patients. Palmar tilt angle, radial inclination angle and radial height were measured and observed using anteroposterior and lateral X-ray films during final follow-up. Wrist function was assessed with Gartland-Werley score. RESULTS AND CONCLUSION:(1) 11 patients were followed and the postoperative follow-up ranged from 7 months to 15 months. X-ray films showed that the union of fractures was achieved in 6-8 weeks (6.5 weeks on average). No infection or internal fixation failure occurred. The articular facets were smooth in 10 patients and a little poor was found in 1 case (<2 mm). (2) After operation, the palmar tilt angle was 8° to 15° (11.55° on average) (P<0.05);the radial inclination angle was 22° to 27° (23.18° on average) (P<0.05);the radial height was 8.01 mm to 13 mm (11.03 mm on average) (P<0.05). (3) The results were excellent in 8 cases, good in 2 cases, and poor in 1 cases according to Gartland-Werley wrist function assessment;the excellent and good rate was 91%. (4) Acu-Loc(R)2 VDR bone plate fixation can provide reliable fixation and effective support for type C distal radius fractures, which can recover the palmar tilt angle, the radial inclination angle and the radial height, so the Acu-Loc(R)2 VDR bone plate is an ideal method to treat type C fractures of the distal radius.
