We aimed to evaluate the advantages of preoperative digital design of skin flaps to repair fingertip defects during the COVID-19 pandemic. We combined digital design with a 3D-printed model of the affected finger for preoperative communication with fingertip defect patients under observation in a buffer ward.
From December 2019 to January 2021, we obtained data from 25 cases of 30 fingertip defects in 15 males and 10 females, aged 20-65 years old (mean 35 ± 5 years). All cases were treated by digitally designing preoperative fingertip defect flaps combined with a 3D-printed model. Preoperative 3D Systems Sense scanning was routinely performed, 3-matic 12.0 was used to measure the fingertip defect area ranging from 1.5 cm × 3.5 cm to 2.0 cm × 5.0 cm, and the skin flap was designed. The flap area was 1.6 cm × 3.6 cm to 2.1 cm × 5.1 cm. CURA 15.02.1 was used to set parameters, and the 3D model of the affected finger was printed prior to the operation. Full-thickness skin grafts were taken from donor areas for repair.
No vascular crises occurred in any of the 25 cases, and all flaps survived. The postoperative follow-up occurred over 3-12 months. All patients were evaluated 3 months after operation according to the trial standard of hand function evaluation of the Chinese Hand Surgery Society. The results showed that 20 cases had excellent outcomes (80%), four cases had good outcomes (16%), and one case had a fair outcome (4%). The excellent and good rate was 96%.
During the COVID-19 epidemic, fingertip defects were treated with preoperative digital design of fingertip defect flaps combined with 3D printing. Precision design saves surgery time and improves the success rate of surgery and the survival rates of skin flaps. In addition, 3D model simulations improve preoperative communication efficiency, and the personalized design improves patient satisfaction.
评估 COVID-19 大流行期间，术前数字化设计皮瓣修复指尖缺损的优势。我们将数字化设计与受影响手指的 3D 打印模型相结合，在缓冲区病房对观察中的指尖缺损患者进行术前沟通。
从 2019 年 12 月至 2021 年 1 月，我们获得了 15 名男性和 10 名女性共 25 例 30 个指尖缺损患者的数据，年龄 20-65 岁（平均 35±5 岁）。所有患者均采用术前数字化设计指尖缺损皮瓣联合 3D 打印模型治疗。常规行术前 3D Systems Sense 扫描，应用 3-matic12.0 测量指尖缺损面积 1.5cm×3.5cm-2.0cm×5.0cm，设计皮瓣。皮瓣面积为 1.6cm×3.6cm-2.1cm×5.1cm。应用 CURA15.02.1 设置参数，术前打印受影响手指的 3D 模型。供区取自体全厚皮片修复。
25 例患者均未发生血管危象，皮瓣全部存活。术后随访 3-12 个月。所有患者术后 3 个月根据中华手外科学会上肢部分功能评定试用标准进行疗效评价。结果显示：优 20 例（80%），良 4 例（16%），可 1 例（4%），优良率为 96%。
在 COVID-19 疫情期间，采用术前数字化设计指尖缺损皮瓣联合 3D 打印治疗指尖缺损。精准设计可缩短手术时间，提高手术成功率和皮瓣成活率。此外，3D 模型模拟可提高术前沟通效率，个性化设计可提高患者满意度。
