ABSTRACT
Objective:To evaluate internal fixation via only the modified Stoppa approach in the treatment of central hip dislocation complicated with fracture of the posterior acetabular wall.Methods:A retrospective study was conducted in the 13 patients with central hip dislocation and fracture of the posterior acetabular wall who had been treated at Department of Orthopedic Trauma, Nanfang Hospital between February 2015 and February 2018. They were 10 men and 3 women, aged from 31 to 65 years (average, 46.7 years). All patients were treated with internal fixation via only the modified Stoppa approach. The reduction of double-column and posterior wall fractures was evaluated according to the X-ray Matta scoring system, as well as to the Wiberg central-edge (CE) angles between the vertical line of the center point of the femoral head and the lateral edge of the acetabulum and acetabular tolerance on the normal and affected sides immediately after operation; the hip function was evaluated by the modified Merle d'Aubigne and Postel scoring system at 12 months after operation.Results:All patients were followed up for 16 to 52 months (average, 25.6 months). In all of them, reduction and fixation of central hip dislocation and acetabular fracture was completed successfully, and indirect reduction of posterior wall fracture and acetabular tolerance were satisfactory. Operation time ranged from 130 to 270 min, averaging 155.5 min; intraoperative blood loss from 600 to 5,600 mL, averaging 1,150.5 mL; intraoperative infusion of concentrated red blood cells from 2 to 12 U, averaging 6 U. By the X-ray Matta scoring system immediately after operation, anatomical reduction was achieved in 4 posterior wall fractures and satisfactory reduction in 9 ones. There was no significant difference between the normal and affected sides in the CE angle (43.53°±3.46° for the affected side versus 43.19°±3.28° for the normal side) or in the acetabular tolerance (76.56%±15.50% for the affected side versus 75.32%±16.24% for the normal side) ( P>0.05). The modified Merle d'Aubigne and Postel scores at 12 months after operation ranged from 12 to 18 points, averaging 16.5 points; the hip function was assessed as excellent in 9 cases, as good in 3 and as fair in one. By the last follow-up, none of the 13 patients lost fracture reduction, and their internal fixation was firm with no loosening or breakage. Conclusion:In the treatment of central hip dislocation complicated with fracture of the posterior acetabular wall, internal fixation via only the modified Stoppa approach can lead to satisfactory fracture reduction, firm fixation, good hip joint tolerance, and fine clinical efficacy.
ABSTRACT
Objective:Toevaluate the short-term outcomes of mere modified Stoppa approach or in addition to ilia fossa approach for acetabular fractures.Methods:From January 2016 to October 2019, 36 patients with acetabular fracture were treated at Department of Traumatology and Orthopaedics, Beijing Jishuitan Hospital. They were 28 males and 8 females with an average age of 45.2 years (from 27 to 78 years). The left side was affected in 15 cases and the right side in 21. By the Judet-Letournel classification, there were 13 anterior column fractures, 3 anterior column and wall fractures, 12 both-column fractures, 6 anterior and posterior hemitransverse fractures, and 2 T-shaped fractures.The time from injury to surgery averaged 6 days(from 2 to 12 days).All the patients were treated by open reduction and plate-screw fixation through the mere modified Stoppa approach or in addition to the ilia fossa approach.The quality of postoperative fracture reduction was evaluated according to the Matta score.The pain scores of visual analogue scale (VAS) for the patients before operation and 18 months after operation were recorded and compared. The fracture healing time, Harris hip score at the last follow-up and complications in the patients were recorded.Results:The average operation time in this cohort was 213.2 min (from 110 to 340 min). By the Matta scores, anatomical reduction was achieved in 28 cases and satisfactory reduction in 8.The 36 patients were followed up for an average of 20 months (from 18 to 25 months). Their VAS pain scores at 18 months after operation were(0.7 ± 0.6) points, significantly lower than those before operation [(6.7 ± 1.3) points] ( P<0.05). Their fracture healing time averaged 3.2 months (from 1.5 to 6.0 months). Their Harris hip scores at the last follow-up averaged 90.6 points (from 80 to 95 points), yielding 26 excellent and 10 good cases.There were no serious complications like internal fixation failure or neurovascular injury during the follow-up period. Conclusions:In the treatment of acetabular fractures, simple modified Stoppa approach or in addition to ilia fossa approach may lead to fine short-term outcomes, because fractures involving both anterior and posterior columns can be handled safely and effectively at the same time.
ABSTRACT
Objective: To explore the effectiveness of the calcaneal plate bridge reconstruction plate for acetabular fracture involving quadrilateral surface via modified Stoppa approach. Methods: Between January 2015 and December 2017, 18 patients with acetabular fracture involving quadrilateral surface were treated with the calcaneal plate bridge reconstruction plate via the modified Stoppa approach. There were 12 males and 6 females. The age ranged from 28 to 63 years (mean, 39 years). The cause of injury was traffic accident in 13 cases and falling from height in 5 cases. According to the Letournel-Judet classification, there were 10 cases of anterior and posterior column fractures, 6 cases of T-shaped fractures, and 2 cases of anterior column and posterior semi-transevere fractures. The interval from injury to operation was 6 to 24 days (mean, 8.6 days). The reduction quality was assessed by postoperative X-ray film and CT according to the criteria proposed by Matta. The hip joint function was assessed by the modified Merled'Aubigné-Postel score. Results: The operation time was 120-240 minutes (mean, 165 minutes) and the intraoperative blood loss was 600-1 400 mL (mean, 850 mL). All patients were followed up 18-30 months (mean, 24.5 months). There were 2 cases of the fat liquefaction of abdominal incisions, 3 cases of intraoperative injury of lateral femoral cutaneous nerve, 1 case of lower limb thrombosis, and 1 case of abdominal pain and hematuria due to intraoperative accidental bladder injury. According to the criteria proposed by Matta, the reduction quality rated as anatomic reduction in 12 cases, satisfactory reduction in 5 cases, and unsatisfied reduction in 1 case, and the satisfaction rate was 94.4%. All fractures healed with the healing time of 3-5 months (mean, 3.4 months). During follow-up, no internal fixator loosening, breakage, or fracture displacement occurred. At last follow-up, according to modified Merled'Aubigné-Postel score, hip joint functions rated as excellent in 11 cases, good in 4 cases, fair in 2 cases, and poor in 1 case. The excellent and good rate was 83.3%. Conclusion: Application of calcaneal plate bridge reconstruction plate via the modified Stoppa approach for the acetabular fracture involving the quadrilateral surface can obtain satisfactory effectiveness.
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
In elderly acetabular fractures, central dislocation of the femoral head and impacted superior dome of the acetabulum is common. Unreduced dome impaction can lead to degenerative arthritis and results in poor results. Herein, we present a case of operative reduction and fixation performed via the modified Stoppa approach in acetabular fracture with superior dome impaction.

ABSTRACT
BACKGROUND: We analyzed the extent of the comminution in the acetabular weight-bearing area, the clinical and radiographic results, and the complications after a minimum 2-year follow-up of the modified Stoppa approach for the treatment of acetabular fractures, and we attempted to evaluate the efficacy of the operative technique. METHODS: All of the 22 patients, who needed the anterior approach for the treatment of acetabular fractures at our hospital from November 2007 to November 2010, were subjected to surgery via the modified Stoppa approach. Fracture pattern, operative time, blood loss during the operation, quality of reduction, number of bony fragments in the acetabular weight-bearing area, and postoperative complications were assessed by retrospectively analyzing the medical records and the radiographic examinations. The results after the operation were analyzed based on the criteria of Matta. RESULTS: The clinical results were excellent in 3 cases, good in 13 cases, and poor in 4 cases, while the radiographic results were excellent in 5 cases, good in 13 cases, and poor in 2 cases. Although the quality of reduction and the clinical results according to the extent of comminution were statistically significant (p = 0.03 and p = 0.04, respectively), the radiographic results were not statistically significant (p = 0.74). CONCLUSIONS: It can be concluded that the modified Stoppa approach could be used as an alternative to the classic ilioinguinal approach. In addition, comminution of the acetabular fracture was an important factor causing non-anatomic reduction and finally unsatisfactory clinical results.

PURPOSE: The purpose of this study is to evaluate the clinical results of modified Stoppa approach in acetabular fractures. MATERIALS AND METHODS: Twelve patients who underwent surgery using the modified Stoppa approach for acetabular fractures were enrolled. There were 10 cases of isolated acetabular fracture, two cases of acetabular fracture combined with pelvic ring injury. There were two cases of anterior column fracture, nine cases of both column fracture, and one case of T-type fracture according to Letournel classification. The clinical outcomes were evaluated from Harris hip score (HHS) at postoperative one year and complications. The radiologic result was evaluated according to Matta criteria; anatomical, imperfect, and poor. RESULTS: According to the radiological results, there were eight cases of anatomical, three cases of imperfect, and one case of poor reduction. The average HHS was 82.5 and 10 patients had excellent or good results. The other two patients had poor results due to lumbosacral plexopathy and poor reduction, respectively. The complication included one case of incomplete sciatic nerve palsy, which was recovered at postoperative three months. CONCLUSION: Internal fixation of acetabular fractures using the modified Stoppa approach had satisfactory clinical and radiological outcomes. The modified Stoppa approach can be a useful option for acetabular fractures with appropriate indication and anatomical information.
