Abstract
ObjectiveTo explore the clinical efficacy of percutaneous internal fixation assisted by 3D printing guide plate for the treatment of scaphoid fracture.
MethodsFrom December 2018 to December 2020, 12 patients with wrist scaphoid fracture were treated. The CT data were collected and the guide plate was printed out with a 3D printer. During the operation, the guide needle was accurately inserted along the guide hole of the guide plate, the fluoroscopy confirmed that the position was satisfactory, the 0.5 cm incision was made, the hollow drill was used, and a hollow compression screw was screwed in. The operation time, fracture healing time, patient self-evaluation wrist questionnaire (PRWE), Mayo wrist function score, flexion, extension and rotation range of affected side and healthy side, radial deviation and ulnar deviation were recorded.
ResultsThe follow-up time was 3 to 20 months, with an average of 7 months. Except for 2 patients who tried to insert the guide needle twice, the rest were successful at one time without deflection. All the patients had good wound healing, no infection, skin necrosis and no fracture nonunion. The operation time was 28 to 77 minutes, with an average of 44.3 minutes. The fracture healing time was 6 to 12 weeks, with an average of 8 weeks. The PRWE score ranged from 0 to 10, with an average of 2.5. The Mayo wrist function score was 80 to 100, with an average of 93.3, of which 9 cases were excellent, 2 cases were good and 1 case was fair. The range of wrist flexion and extension was (145.67±8.72) ° on the affected side and (149.92±5.23) ° on the healthy side. The range of rotation was (147.00±7.25) ° on the affected side and (148.92±6.72) ° on the healthy side. The radial deviation angle was (16.50±1.83) ° on the affected side and (17.17±1.80) ° on the healthy side. The ulnar deviation angle was (26.33±1.37) ° on the affected side and (27.25±1.71) ° on the healthy side. There was no significant difference between the affected side and the healthy side (P>0.05).
ConclusionThe application of minimally invasive percutaneous internal fixation assisted by 3D printing guide plate for the treatment of scaphoid fracture has the advantages of less trauma, short operation time, good functional recovery, and individualization, safety and accuracy.
