| Background Malunion of fracture distal radius can cause pain and functional impact. Numerous surgical techniques have been implemented. Distraction osteogenesis allows gradual deformity correction and avoids bone grafting complications. This retrospective study aims to assess the results of distraction osteogenesis for the treatment of malunited distal radius fractures. Patients and Methods Between February 2019 and March 2023, 12 patients (eight males and four females) with malunited distal radius fractures were managed with an Ilizarov external fixator. The corticotomy was done through a small dorsal incision. The lengthening was started 10 days postoperatively at a rate of 0.25mm every 6h until the deformity was corrected. Results The average age of the patients was 30±2.5 years. The average follow-up time was 25.2±11 months. After an average of 2.5±0.6 months, the external fixator was removed. The average radius shortening was 9±4.150mm with an average lengthening of 12±2.189mm. A preoperative average of +3.7mm ulnar variance decreased to +0.62mm at the final follow-up with a statistically significant difference (P=0.017). Angular deformity improved from a preoperative average of 28±2.4570 dorsal tilt to an average of 5±2.5380 palmar tilt at the final follow-up with a statistically significant difference (P=0.01). A preoperative average of 12±6.1500 radial inclination improved to 20±9.1890 at the final follow-up with a statistically significant difference (P=0.01). One patient was complicated with Sudeck’s atrophy. Statistically significant differences could be found as regards pain, grip strength, active range of motion of the affected wrist, mean Disabilities of the Arm, Shoulder and Hand score, and mean modified Mayo Wrist Score between the preoperative measurements and at the final follow-up (P=0.01, 0.012, 0.027, 0.014, and 0.001, respectively). Conclusions Distraction osteogenesis with Ilizarov is a safe and effective procedure for the treatment of malunited distal radius fractures. It could correct the deformity and establish good functional results. | ||
