Clinical efficacy analysis of 3D printing as assisted therapy for youth Salter-HarrisⅡ distal fracture of radius
Objective To investigate the value of 3D printing technology in the treatment of unstable distal radius fractures of children and adolescents with Salter-Harris II type. Methods The clinical data of 19 cases with unstable distal radius fractures of Salter-Harris type II with 3D printing technique were retrospectively analyzed. The basic parameters such as operation time and intraoperative blood loss were recorded. The growth of the affected limb, recovery of wrist joint function, and complications after follow-up were recorded. The clinical efficacy was preliminarily evaluated. Results The direction, length, and diameter of the needle in the 19 patients were consistent with the preoperative simulation. Operating time was 17~39 min, with an average of 21.6 min; intraoperative blood loss was 0~10 ml, with an average of 4.5 ml; intraoperative fluoroscopy was used 4 to 6 times, with an average of 5 times; anatomical reduction of fractures were achieved in 17 cases, and postoperative fracture displacement less than 2 mm was achieved in 2 cases. All 19 patients were followed up for 12 to 20 months with an average of 14.5 months. All the affected limbs reached bone healing. Postoperative assessment of wrist function was performed using the Gartland-Werley scoring system 12 months after surgery: excellent in 18 cases, and normal in 1 case. Conclusion 3D printing technology as an auxiliary technique has certain clinical application value for children and adolescents with unstable Salter-Harris type II distal humeral fracture.
