- Abstract:
- Objective To explore the feasibility of utilizing three-dimensional (3D) printing technology for designing a lateral closing wedge osteotomy plate for assisting in osteotomy for cubitus varus deformity in children.Methods Retrospective analysis was conducted for the relevant clinical data of 45 children of cubitus varus deformity treated with the assistance of a 3D printed lateral closing wedge osteotomy plate from January 2020 to January 2022 in the pediatric orthopaedic ward of Chia Tai Shaoyang Orthopedic Hospital.There were 35 boys and 10 girls.The involved side was left (n=24) and right (n=21).Perioperative values of carrying angle,anteversion angle and range of motion of elbow joint were measured.Elbow joint function was assessed by the Oppenheim Elbow Function Score.Results At the last follow-up,carrying angle of affected elbow joint was (11.3±1.6)°.There was no statistically significant difference as compared to unaffected side (P=0.085>0.05).Maximal extension angle of affected limb at the last follow-up ranged from -10° to 15° (average 3.7°) and maximal flexion angle ranged from 125° to 145° (average 134.6°).There was no statistically significant difference as compared to unaffected side (P=0.12>0.05).According to the Oppenheim Elbow Function Score,the excellent/decent rate was 93%.Conclusions For cubitus varus deformity in children,using a 3D printed lateral closing wedge osteotomy plate for assisting in osteotomy may offer a simpler,more accurate and mini-invasive correction,achieving favorable clinical outcomes.
