- Abstract: Objective To investigate the clinical value of individual design combined with 3D-guided percutaneous hollow screw fixation for patients with Herbert Ⅰb-type scaphoid fractures.Methods Totally 93 cases of Herbert Ⅰb-type scaphoid fractures patients who were admitted into our hospital from November 2015 to April 2017 were divided into the external fixation group(31 cases),the internal fixation group(29 cases)and the minimal invasion group(33 cases).The external fixation group was treated with cast immobilization;the internal fixation group was treated with open reduction and internal fixation;the minimal invasion group was treated with individual design combined with 3D-guided percutaneous hollow screw fixation.The time of bone union,return-to-work time,rateof bone union,wrist range of motion (ROM)and Mayo function score of the three groups were compared.Results The time of bone union,return-to-work time and wrist range of motion in the minimal invasion group were(6.7 ±0.9)weeks,(7.3 ±0.9)weeks and(103.8 ±5.9)°respectively,which were better than the other two groups with statistically significant difference(P<0.05).The bone union rate of the external fixation group,the internal fixation group,and the minimal invasion group were 83%,86.2%and 100%respectively.The difference between the minimal invasion group and the other two groups were statistically significant(P<0.05).The Mayo function score of the external fixation group,the internal fixation group, and the minimal invasion group were 71.0%,82.8% and 97.0% respectively.The difference between the minimal invasion group and the other two groups were statistically significant(P<0.05).Conclusion Individual design combined with 3D-guided percutaneous hollow screw fixation treatment has exact effect for Herbert Ⅰb-type scaphoid fractures with fast recovery,and it's worthy of wildly use.
