Abstract:
Objective To investigate the curative effect of bone plate screw external fixation minimally invasive treatment assisted with 3-dimensional printing extraposition mold in distal radius fractures.Methods The clinical and follow up data in 15 cases of distal radius fractures treated by bone plate screw ex-ternal fixation minimally invasive treatment assisted with 3-dimensional printing extraposition mold were ret-rospectively analyzed.The volar inclination angle,ulnar deviation angle,radius length at the time of before surgery,immediately after surgery,and 2 years after surgery were measured,by using standard anteroposterior and lateral X-ray films,as well as the wrist jiont flexion extension motion and dorsal extension motion at the time of 2 years after surgery were measured by using protractor.The grip strength of the hand 2 years after surgery was measured by using grip strength meter.Visual Analog Scale(VAS)score was used to evaluate the pain level or wrist joint before and 2 years after surgery;Gartland Werley score was used to evaluate the wrist joint function 2 years after surgery.Results The follow-up lasted for 24.0-33.0 months with an aver-age of 26.5 months.The Gartland-Werley scores were excellent in 12 cases,good in 2 cases and fair in 1 case 2 years after surgery.The wrist joint flexion motion was(52.0±11.7)°,the wrist joint dorsal extension motion was(65.0±4.8)°,the grip strength of the affected side was(84.0±4.2)％of the healthy side.Compared with before operation,the volar inclination angle,ulnar deviation angle and radius shortening value and VAS score up were significantly improved 2 years after surgery(P＜0.05),and there was no statistically significant difference in immediately after surgery imaging parameters(volar inclination angle,ulnar deviation angle and radius shortening)immediately after surgery compared to 2 years after surgery(P＞0.05).Conclusion The bone plate screw external fixation minimally invasive treatment assisted with 3-dimensional printing extrapo-sition mold in distal radius fractures has the advantages of individualized bone plate screw,precision guidance position angle,minimal invasion,low demand for skin and soft tissue condition and easy taking out.The fixa-tion is reliable and the joint function recovered well and the short follow up effect is satisfactory.
