  • Comparison of effectiveness between two combined anterior and posterior approaches for complicated acetabular fractures

    ObjectiveTo compare the effectiveness between modified ilioinguinal approach combined with Kocher-Langenbeck (K-L) approach and Stoppa approach combined with K-L approach for the treatment of complicated acetabular fractures.MethodsBetween May 2011 and May 2016, Sixty-two patients with complicated acetabular fractures were treated with operation via combined anterior and posterior approaches. Thirty-four cases (group A) were treated with modified ilioinguinal approach combined with K-L approach, and 28 cases (group B) were treated with Stoppa approach combined with K-L approach. There was no significant difference in gender, age, injury causes, the type of fracture, time from injury to operation, and associated injury between 2 groups (P>0.05). The operation time, intraoperative blood loss, and hospitalization time were recorded. X-ray film was performed to evaluate the fracture reduction according to the Matta reduction criteria and observe the fracture healing, osteoarthritis, and heterotopic ossification. Clinical results were evaluated according to the grading system of modified d’Aubigne and Postel.ResultsThere was no significant difference in operation time, intraoperative blood loss, and hospitalization time between 2 groups (P>0.05). Postoperative incision fat liquefaction occurred in 2 cases in group A and group B respectively, and deep vein thrombosis of lower extremity occurred in 1 case in group A. No iatrogenic injury was found in 2 groups. Fifty-six patients were followed up after operation. Thirty patients in group A were followed up 12-48 months (mean, 31.8 months). Twenty-six patients in group B were followed up 12-46 months (mean, 30.2 months). At 12 months after operation, according to the grading system of modified d’Aubigne and Postel, the hip function was rated as excellent in 9 cases, good in 16 cases, fair in 3 cases, and poor in 2 cases, with the excellent and good rate of 83.3% in group A; the hip function was rated as excellent in 7 cases, good in 14 cases, fair in 2 cases, and poor in 3 cases, with the excellent and good rate of 80.8% in group B. There was no significant difference in the hip function between 2 groups (Z=0.353, P=0.724). The X-ray films showed that there were 23 cases of anatomical reduction, 6 cases of satisfactory reduction, and 1 case of unsatisfactory reduction in group A, and 20 cases, 5 cases, and 1 case in group B, respectively. There was no significant difference in the results of fracture reduction between 2 groups (Z=0.011, P=0.991). Fracture healing was observed in both groups. There was no significant difference in fracture healing time between 2 groups (t=0.775, P=0.106). During follow-up, 5 cases of osteoarthritis changes, 2 cases of heterotopic ossification, and 2 cases of avascular necrosis of femoral head occurred in group A, and 4 cases, 2 cases, and 1 case in group B, respectively.

    Objective To investigate the effectiveness of HoloSight Orthopaedic Trauma Surgery Robot-assisted infra-acetabular screw placement for treatment of acetabular fractures. Methods The clinical data of 23 patients with acetabular fractures treated with open reduction and internal fixation and infra-acetabular screw placement in two medical centers between June 2022 and October 2023 were retrospectively analyzed. According to the the method of infra-acetabular screw placement, the patients were divided into navigation group (10 cases, using HoloSight Orthopaedic Trauma Surgery Robot-assisted screw placement) and freehand group (13 cases, using traditional X-ray fluoroscopy to guide screw placement). There was no significant difference in gender, age, body mass index, cause of injury, time from injury to operation, and Judet-Letournel classification between the two groups (P>0.05). The time of infra-acetabular screw placement, the fluoroscopy frequency, the guide pin adjustment times, the quality of screw placement, the quality of fracture reduction, and the function of hip joint were compared between the two groups. ResultsAll patients completed the operation successfully. The time of screw placement, the fluoroscopy frequency, and guide pin adjustment times in the navigation group were significantly less than those in the freehand group (P<0.05). The quality of screw placement in the navigation group was significantly better than that in the freehand group (P<0.05). Patients in both groups were followed up 6-11 months, with an average of 7.7 months. There were 9 and 9 cases in the navigation group and the freehand group who achieved excellent and good fracture reduction quality at 1 week after operation, and 12 and 12 cases with excellent and good hip joint function at last follow-up, respectively, and there was no significant difference between the two groups (P>0.05). The fractures in both groups healed well, and there was no significant difference in healing time (P>0.05). During the follow-up, there was no complication related to screw placement, such as failure of internal fixation, vascular and nerve injury, incisional hernia. ConclusionIn the treatment of acetabular fractures, compared with the traditional freehand screw placement, the HoloSight Orthopaedic Trauma Surgery Robot-assisted screw placement can reduce the time of screw placement, improve the accuracy of screw placement, and reduce the amount of radiation, which is an efficient, accurate, and safe surgical method.

    Objective To evaluate the security and effectiveness of minimal invasive fixation with three dimensional (3D) fluoro-images based on navigation system in the management of acetabular fractures. Methods Between August 2008 and January 2010, 12 patients with acetabular fractures were treated with percutaneous screw fixation under the guidance of 3D fluoro-images based on navigation system after closed reduction. There were 7 males and 5 females, aged 28-57 years (mean, 38.1 years). Fractures were caused by traffic accident in 9 cases, and fall ing from height in 3 cases. According to AO classification, there were 1 case of A2.2 type, 3 cases of A2.3 type, 2 cases of A3.2 type, 2 cases of A3.3 type, 1 case of B2.2 type, 1 case of B3.2 type, 1 case of C2.1 type, and 1 case of C2.3 type. The interval from injury to hospital ization was 4 hours to 3 days (mean, 1.2 days). Results Totally 28 screws were implanted. The average time to implant 1 screw was 24.8 minutes. Twenty-seven screws were placed correctly with a successful rate of 96.4%, only 1 screw was reinserted for deviation. All the screws were checked by the 3D fluoro-images, which showed they were not in the joint space after fixation. The results were the same as that by CT scanning. Incisions healed by first intention, and no implant failure occurred. All 12 patients were followed up 7 to 24 months with an average of 16.8 months. At last follow-up, fracture union was achieved in all patients with satisfactory screw fixation. Conclusion The minimal invasive fixation with 3D fluoro-images based on navigation system makes the surgery for the nondisplaced acetabular fracture more precise and time-saving, minimizes the surgery injury, and improves the cl inical results with less compl ications.
