Objective  To investigate the surgical technique and effectiveness of volar locking plates for senile delayed distal radius fractures. Methods  Between October 2014 and September 2015, 25 cases of delayed distal radius fractures were treated by volar locking plates. There were 3 males and 22 females with an average age of 73 years (range, 65-87 years). Injury was caused by tumble in 19 cases and by traffic accident in 6 cases. All the cases had closed fracture. According to the AO classification, 10 cases were rated as type A2, 7 cases as type A3, 3 cases as type B3, and 5 cases as type C1. The manual reduction and plaster immobilization were performed in 18 cases first, but reduction failed; no treatment was given in 7 cases before surgery. The time from injury to surgery was from 33 to 126 days (mean, 61 days). Preoperatively, the volar tilting angle was (–16.0±3.1)°; the ulnar inclining angle was (10.8±7.0)°; the radial shortening was (11.2±3.6) mm; the wrist range of motion was (41.0±7.5)° in flexion and was (42.0±6.3)° in extension; and the grip strength was 33.0%±3.1% of normal side. Results  All incisions healed primarily, and no postoperative complication occurred. The patients were followed up 1-1.5 years (mean, 1.3 years). The X-ray films showed that fracture union was achieved in all the patients, with the mean healing time of 9.2 weeks (range, 8-12 weeks); the displacement of the articular surface was less than 1 mm. At last follow-up, the volar tilting angle was (13.1±3.2)°; the ulnar inclining angle was (21.9±4.6)°; the radial shortening was (2.0±1.1) mm; the wrist range of motion was (52.0±11.7)° in flexion and was (65.0±4.8)° in extension; and the grip strength was 84.0%±4.2% of normal side; all showed significant difference when compared with preoperative ones (P<0.05). According to the Gartland and Werley score, the results were excellent in 15 cases, good in 6 cases, fair in 2 cases, and poor in 2 cases at last follow-up; the excellent and good rate was 84%. Conclusion  By the good design of the volar locking plate and the command of surgical techniques, good effectiveness can be achieved in the treatment of senile delayed distal radius fracture.
