ABSTRACT
Objective: To 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. Methods: Between 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. Results: There 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. The difference between 2 groups was not significant ( P>0.05). Conclusion: According to the location and type of fracture, making a choice between the modified anterior approach and Stoppa approach, and then combined with K-L approach for treatment of complicated acetabular fracture, can obtain satisfactory effectiveness.
ABSTRACT
We have treated thirteen complex plateau fractures involving both condyles with one of the following conditions with the use of the combined anterior and posterior approaches in a modified supine position. Associated PCL avulsion fracture, displacement of major fracture plane dominantly at the back, large coronal fracture fragment involving medial or lateral condyles. A patient is placed on an operation table in supine position with a bump under the contralateral buttock. The well leg is placed in a lithotomy position and the injured leg is placed over a sterilized Mayo stand separately. For the posterior approach the table was tilt toward the injured side with the hip abducted and rotated externally. With a modified patient's positioning we were able to use combined anterior and posterior approaches simultaneously for the management of certain complex plateau fractures without changing the draping.
