Purpose: The purpose of this study was to evaluate clinical and radiological results after open reduction and internal fixation of unstable distal radius fractures by using volar locking plates.
Materials and Methods: There were 73 consecutive unstable distal radius fractures treated by open reduction internal fixation using a volar locking plate. The mean age of patients was 55.5 years (range: 17-85 years): the study included 41 women and 32 men. The mean duration of follow up was 25.5 months (6.1-63.7 months). There were 18 type A, 5 type B, and 50 type C fractures by AO classification. For clinical evaluation, Green & O’Brien’s modified scoring system and Demerit Point system were used. For radiological evaluation, radiographic index (radial length and radial inclination, volar tilt and ulnar variance) and Sarmiento’s Criteria for Anatomic results were assessed. And, clinical results, the difference of mentioned radiographic index at preoperation, and immediate postoperative and last follow-up were compared according to AO classification and bone mineral density (BMD).
Results: Clinical results by the Green & O’Brien’s scoring system were as follows: 46 excellent, 17 good, 9 fair, 1 poor by demonstrating more than good results in 86.3% of all cases. According to the Demerit point system, there were 50 excellent, 16 good, and 7, which showed more than good results in 90.4% of all cases. Bone union was achieved in all cases. Sarmiento Criteria showed 36 excellent, 21 good, and 16 fair. There were statistically significant improvements between preoperative and postoperative radial length, radial inclination, volar tilt and ulnar variance (p<0.05), whereas there were no statistically significant differences between those at immediate postoperative and last follow-up. There were no statistically significant differences in clinical results, measurements of radial length, radial inclination, volar tilt and ulnar variance between intragroup and intergroup, or in immediate postoperative and last follow-up according to fracture type and BMD.
Conclusion: Volar locking plate fixation for distal radius fracture offers rigid fixation with insignificant reduction loss. It enables early rehabilitation and showed satisfactory clinical and radiological results. It is considered as an effective treatment option, regardless of fracture type and osteoporosis.
