对于外科医生来说,治疗肩胛骨骨折仍然是一项具有挑战性的任务。我们旨在评估可行性,准确度,增强现实(AR)和三维(3D)板库辅助后路微创手术的有效性,命名为AR-肩胛骨系统的肩胛骨骨折。我们推测使用AR-肩胛骨系统可以提高肩胛骨骨折手术的效率和质量。
我们回顾性回顾了21例肩胛骨骨折患者后路微创手术重建钢板治疗的记录:I组9例患者采用常规固定治疗;而12例患者采用术前虚拟仿真和手术中使用AR-肩胛骨系统的导航辅助固定治疗。我们比较了手术时间,失血,并发症,和Hardegger函数在两组之间。统计分析评估了这些变量中每个变量的组间的显著差异。
在第二组中,术前虚拟仿真时间为44.42±15.54min。术前对板进行轮廓所需的时间为16.08±5.09分钟。II组患者手术时间明显缩短,出血量少(-28.75min和-81.94ml,分别为;P<0.05)优于常规手术组患者。使用的平均板数在I组中为1.56±0.53,在II组中为1.25±0.45。差异无统计学意义(P>0.05)。两组随访功能结局结果相似(P>0.05)。所有患者均无术中或术后并发症。
增强现实和3D钢板库辅助的后路微创手术是治疗肩胛骨骨折的有效和可靠的方法,可以提供精确的术前计划和术中导航。这种节省时间的方法可以给出更定制的治疗计划,允许更安全的复位手术。更重要的是,便携式投影仪便宜且易于使用。
Treating scapular fractures is still a challenging task for surgeons. We aimed to evaluate the feasibility, accuracy, and effectiveness of augmented reality (AR) and three-dimensional (3D) plate library-assisted posterior minimally invasive surgery, named AR-scapular system for scapula fracture. We speculated that using AR-scapular system would improve efficiency and quality for scapular fracture surgery.
We retrospectively reviewed the records of 21 patients with scapular fractures treated by posterior minimally invasive surgery with reconstruction plates: nine patients were treated with conventional fixation in group I; whereas 12 patients were treated with pre-operative virtual simulation and intra-operative navigation-assisted fixation using AR-scapular system. We compared operative time, blood loss, complication, and Hardegger function between two groups. Statistical analyses evaluated significant differences between the groups for each of these variables.
In group II, the pre-operative virtual simulation time was 44.42 ± 15.54 min. The time required for pre-operative contouring of the plates was 16.08 ± 5.09 minutes. The patients in group II had significantly shorter operation time and less blood loss (- 28.75 min and - 81.94 ml, respectively; P < 0.05) than patients in the conventional surgery group. The average numbers of plates used were 1.56 ± 0.53 in group I and 1.25 ± 0.45 in group II. The difference was not statistically significant (P > 0.05). The follow-up function outcome results were similar between groups (P > 0.05). There were no intra-operative or post-operative complications for all patients.
Augmented reality and 3D plate library-assisted posterior minimally invasive surgery is an effective and reliable method for treating scapular fractures which can provide precise pre-operative planning and intraoperative navigation. This time-saving approach can give a more customized treatment plan, allowing for a safer reduction surgery. What is more, the portable projector is cheap and easy to use.
