  • 内置固定架治疗骨盆骨折致股神经麻痹三例

    目的总结皮下前环内置固定架(INFIX)治疗骨盆骨折致股神经麻痹的原因及处理方法。 方法回顾2013年4月-2015年1月经INFIX方法治疗后发生股神经麻痹的3例骨盆骨折患者临床资料。其中女2例,男1例;年龄分别为26、19、51岁;均为交通事故致伤。INFIX方法治疗后出现股神经麻痹症状,经影像学、神经电生理及彩色超声多普勒检查确诊。待骨折愈合后,二次手术取出内固定物,并联合营养神经治疗;其中2例行股神经松解。 结果患者分别获随访12、22、15个月,股四头肌肌力恢复至4级,可负重行走伴跛行。 结论INFIX治疗骨盆骨折时,如螺钉植入过深、连杆安放层次错误、连杆折弯不充分均可能导致股神经麻痹。对症处理后仍存在股四头肌力量弱以及步态改变。

  • Orthopedic robot based on 5G technology for remote navigation of percutaneous screw fixation in pelvic and acetabular fractures

    Objective To investigate the accuracy and safety of percutaneous screw fixation for pelvic and acetabular fractures with remote navigation of orthopedic robot based on 5G technology. Methods Between January 2021 and December 2021, 15 patients with pelvic and/or acetabular fractures were treated with percutaneous screws fixation which were placed by remote navigation of orthopedic robot based on 5G technology. There were 8 males and 7 females. The age ranged from 20 to 98 years, with an average of 52.1 years. The causes of trauma included traffic accident injury in 6 cases, falling from height injury in 6 cases, fall injury in 2 cases, and heavy object smashing injury in 1 case. The time from injury to operation ranged from 3 to 32 days, with an average of 10.9 days. There were 8 cases of simple pelvic fractures, 2 simple acetabular fractures, and 5 both pelvic and acetabular fractures. There were 7 cases of pelvic fractures of Tile type B2, 2 type B3, 1 type C1, and 3 type C2; 4 cases of unilateral anterior column fracture of the acetabulum, 2 bilateral anterior column fractures, and 1 anterior wall fracture. CT images within 5 days after operation were collected for screw position assessment. The screw planning time and guidewire placement time were recorded, as well as the presence of intraoperative adverse events and complications within 5 days after operation. Results All patients achieved satisfactory surgical results. A total of 36 percutaneous screws were inserted (20 sacroiliac screws, 6 LC Ⅱ screws, 9 anterior column screws, and 1 acetabular apical screw). In terms of screw position evaluation, 32 screws (88.89%) were excellent and 4 screws (11.11%) were good; there was no screw penetrating cortical bone. The screw planning time ranged from 4 to 15 minutes, with an average of 8.7 minutes. The guidewire placement time ranged from 3 to 10 minutes, with an average of 6.8 minutes. The communication delayed in 2 cases, but the operation progress was not affected, and no serious intraoperative adverse events occurred. No delayed vascular or nerve injury, infection, or other complications occurred within 5 days after operation. No cases need surgical revision. ConclusionThe fixation of pelvic and acetabular fractures by percutaneous screw with remote navigation of orthopedic robot based on 5G technology is accurate, safe, and reliable.

  • Effectiveness of reduction robot combined with navigation robot-assisted minimally invasive treatment for Tile type B pelvic fractures

    Objective To explore the effectiveness of reduction robot combined with navigation robot-assisted minimally invasive treatment for Tile type B pelvic fractures. Methods Between January 2022 and February 2023, 10 patients with Tile type B pelvic fractures were admitted. There were 6 males and 4 females with an average age of 45.5 years (range, 30-71 years). The fractures were caused by traffic accident in 5 cases, bruising by heavy object in 3 cases, and falling from height in 2 cases. The interval between injury and operation ranged from 4-13 days (mean, 6.8 days). There were 2 cases of Tile type B1 fractures, 1 case of Tile type B2 fracture, and 7 cases of Tile type B3 fractures. After closed reduction under assistance of reduction robot, the anterior ring was fixed with percutaneous screws with or without internal fixator, and the posterior ring was fixed with sacroiliac joint screws under assistance of navigation robot. The time of fracture reduction assisted by the reduction robot was recorded and the quality of fracture reduction was evaluated according to the Matta scoring criteria. The operation time, intraoperative fluoroscopy frequency and time, intraoperative bleeding volume, and incidence of complications were also recorded. During follow-up, the X-ray film of pelvis was taken to review the fracture healing, and the Majeed score was used to evaluate hip joint function. Results The time of fracture reduction was 42-62 minutes (mean, 52.3 minutes). The quality of fracture reduction according to the Matta scoring criteria was rated as excellent in 4 cases, good in 5 cases, and poor in 1 case, with excellent and good rate of 90%. The operation time was 180-235 minutes (mean, 215.5 minutes). Intraoperative fluoroscopy was performed 18-66 times (mean, 31.8 times). Intraoperative fluoroscopy time was 16-59 seconds (mean, 28.6 seconds). The intraoperative bleeding volume was 50-200 mL (range, 110.0 mL). No significant vascular or nerve injury occurred during operation. All patients were followed up 13-18 months (mean, 16 months). X-ray films showed that all fractures healed with the healing time of 11-14 weeks (mean, 12.3 weeks). One case of ectopic ossification occurred during follow-up. At last follow-up, the Majeed score was 70-92 (mean, 72.7), and the hip joint function was rated as excellent in 2 cases and good in 8 cases, with the excellent and good rate of 100%. Conclusion The reduction robot combined with navigation robot-assisted minimally invasive treatment for Tile type B pelvic fractures has the characteristics of intelligence, high safety, convenient operation, and minimally invasive treatment, which can achieve reliable effectiveness.
