利用计算机辅助、3D打印技术精准矫形踇外翻一例

摘要

目的 探讨利用计算机辅助、3D打印技术行踇外翻矫形手术治疗的临床疗效，寻找更精确的治疗方式提高手术效率及减少手术并发症。方法 结合相关文献，对1例中度踇外翻患者术前通过计算机辅助、3D打印技术制定术中踇外翻截骨矫形方案，观察患者术后双足矫形情况及并发症。结果 患者，女性，70岁，因“双足踇趾疼痛、活动受限1年余”于2023-10-16入院。入院后完善相关检验检查，诊断：双足踇外翻，于2023-10-18在腰硬联麻醉下行“双足踇趾滑囊切除伴软组织松解、计算机辅助第一跖骨截骨矫形内固定、右足第1趾骨截骨内固定、双下肢石膏托外固定术”，术后定期止痛、清创换药等对症支持治疗后，切口愈合良好，于2023-10-16出院。结论 利用计算机辅助于术前模拟制定矫形方案，同时3D打印技术制作术中截骨导向板，可以精准定位辅助截骨矫形，减少损伤，提高手术效率，减少术后并发症，为临床上踇外翻畸形矫正患者提供个体化、精准化的治疗方案，为广大外科医师术中手术矫形方式提供指导和理论依据。

Abstract

Objective: To explore the clinical effect of computer-assisted and 3D printing technology, and to find more accurate treatment methods to improve surgical efficiency and reduce surgical complications.
Methods Combined with relevant literature, the intraoperative orthopedic plan of moderate hallux valgus was made for a patient with computer assistance and 3D printing technology, and the postoperative orthopedic situation and complications of both feet were observed.
Results The patient, female, 70 years old, was admitted to the hospital in 2023-10-16 due to "pain in hallux for more than 1 year". After admission, improve relevant inspection and examination, diagnosis: double foot hallux valgus, in 2023-10-18 in lumbar hard anesthesia" double foot hallux capsule resection with soft tissue release, computer-assisted first metatarsal resection, internal fixation of right foot, double lower limb plaster fixation", after regular postoperative analgesia, debridement and dressing for symptomatic support treatment, the incision healed well and was discharged on 2023-10-16.
Conclusion   Using computer assistance in preoperative simulation for orthopedic plan, at the same time 3D printing technology to make intraoperative osteotomy guide plate, can accurately positioning auxiliary osteotomy, reduce damage, improve the efficiency of surgery, reduce postoperative complications, for clinical patients with hallux valgus deformity correction provide individualized and accurate treatment, for the surgeons intraoperative surgery orthopedic way to provide guidance and theoretical basis.
