3D打印结合虚拟手术辅助治疗C型桡骨远端骨折
Surgical treatment of type-C distal radius fractures assisted with 3D printing technique and virtual surgery
摘要
Abstract
Objective To investigate the radiologic and functional outcome following internal fixation of type-C distal radius fractures assisted with 3D printing technique and virtual surgery. Methods Total 17 type-C distal radius frac-tures patients underwent open reduction and internal fixation(ORIF) assisted with 3D printing technique and virtual surgery. According to the data of CT scan, models of fractures used for classification were produced by 3D printer. The virtual surgery was completed on the computer, and preoperative planning was made at the same time. The real surgical procedures were carried out accurately according to the preoperative planning. The durations of operations and volume of blood loss were recorded. Healing time, fracture reduction, and wrist function recovery were evaluated when follow-up after surgery. Results The durations of operations were 28～76 min, and volume of intraoperative blood loss was 20～75 ml. All cases were followed up for 6～18 months. All fractures healed with time of 8.2～11.5 weeks. At 6 months postoperation, radial height was 7.2～12.7 mm, palm tilt angle was 7.1° ～14.9°, deviation angle was 14.8°～27.3°. According to the Sarmiento criteria, the results were excellent in 10 cases, good in 6, fair in 1. For wrist functional assessment, the patients were assessed by the Dienst scale criteria, the results were excel-lent in 12 cases, good in 4, fair in 1. Conclusions The 3D printing models are helpful for surgeons to have a direct visualization of the fractures. And virtual surgery can provide patient-specific preoperative planning, which make ac-curate surgery be possible. The radiologic and functional outcome of type-C distal radius fractures treated by ORIF as-sisted with 3D printing technique and virtual surgery are satisfied.关键词
