A novel technique for stabilising sacroiliac joint dislocation using spinal instrumentation: technical notes and clinical outcomes

Purpose Currently, sacroiliac joint dislocations, including crescent fracture–dislocations, are treated using several techniques that have certain issues. We present the technical details and clinical outcomes of a new technique, anterior sacroiliac stabilisation (ASIS), performed using spinal instrumentation. Methods ASIS is performed with the patient in a supine position via the ilioinguinal approach. The displacements are reduced and fixed by inserting cancellous screws from the sacral ala and iliac brim; the screw heads are bridged using a rod and locked. We performed a retrospective review of patients with iliosacral disruption who underwent ASIS between May 2012 and December 2020 at two medical facilities. The patients were assessed for age, sex, injury type, associated injuries, complications, functional outcome by evaluating the Majeed pelvic score after excluding the sexual intercourse score and fracture union. Results We enrolled 11 patients (median age: 63 years). The median operative time was 195 min, median blood loss was 570 g, and eight patients (72.3%) required blood transfusion. The sacral and iliac screws had a diameter of 6.0–8.0 mm and 6.2–8.0 mm, and a length of 50–70 mm and 40–80 mm, respectively. Bone union was achieved with no marked loss of reduction in the median follow-up period of 12 months in all cases. The median Majeed score at the final follow-up was 85/96. Conclusion ASIS is a rigid internal fixation method that provides angular stability. Despite invasiveness issues compared to iliosacral screw fixation, this method is easy to confirm and achieves precise reduction.

Anterior intrapelvic approach and suprapectineal quadrilateral surface plate for acetabular fractures with anterior involvement: a retrospective study of 34 patients

Background The purpose of the study is to evaluate the use of the suprapectineal quadrilateral surface (QLS) plates associated with the anterior intrapelvic approach (AIP) to the acetabulum in the surgical treatment of acetabular fractures with anterior involvement. Methods We did a retrospective study of patients surgically treated with QLS plates and AIP for acetabular fractures with the involvement of the anterior column, between February 2018 and February 2020, in our Hospital. The following data were recorded: mechanism of injury, the pattern of fracture, presence of other associated injuries, the time before performing the surgery, surgical approach, position on operating table, time of surgery, intraoperative bleeding, hospitalization time, intraoperative and postoperative complications. Follow-ups were performed at 1, 3, 6, 12 months, then annually. The clinical-functional outcome was assessed with the Merle d’Aubigne Postel score (MAP) modified by Matta; while the radiological outcome with the Matta Radiological Scoring System (MRSS). A Chi-square test was utilized to examine associations between parametric variables. Results We included 34 patients, mean age 62.1, with an average follow-up of 20.7 months. The most frequent traumatic mechanism was road trauma. There were 15 isolated anterior columns and 19 associated patterns. There were 5 cases of associated visceral injuries, and 10 cases of other associated skeletal fractures. All patients were in the supine position. The surgical approach used was the AIP in all cases, with the addition of the first window of the ilioinguinal approach in 16 cases and of the Kocher-Langenbeck approach in 2 cases. The average time before performing the surgery was 8.5 days. The mean time of the surgery and the mean length of stay after surgery were 227.9 min and 8.2 days, respectively. There weren’t cases of intra-operative complications, while there were postoperative complications in 5 patients. The MRSS was judged anatomical in 26 cases, imperfect in 7 cases and poor in 1 case. The average MAP value was 15.2. We observed a significant relationship between the radiological outcome and the clinical outcome (p < 0.05). Conclusions The QLS plates in association with the AIP approach represent an effective treatment strategy for the treatment of acetabular fractures with anterior involvement.

Intrapelvic Pseudotumor Causing Neuropathy and Vascular Obstruction After Revision Total Hip Arthroplasty: A Case Report

Background: There is a growing body of recent literature regarding the occurrence of pseudotumors associated with modular junctions and various bearing surfaces after total hip arthroplasty (THA). Revision surgery is often technically challenging and high complication rates have been reported. The optimal management of these patients and outcomes after operative treatment remain poorly understood. Methods: We report the case of a 77-year-old male with progressive unilateral lower extremity swelling, pain, and neuropathy 9 years after revision THA for polyethylene liner wear. Imaging and biopsy confirmed a massive intrapelvic pseudotumor exerting compressive effects. Radiographs demonstrated extensive femoral and pelvic osteolysis without evidence of component loosening. Debulking of the intrapelvic portion of the pseudotumor was performed via the lateral window of the ilioinguinal approach with component retention. Results: Debulking of the intrapelvic mass resulted in resolution of symptoms. One year postoperatively the patient reported pain free ambulation using a walker and no recurrence of symptoms. Radiographs demonstrated stable THA components in comparison with preoperative films. Discussion and Conclusion: This case demonstrates a rare finding of intrapelvic pseudotumor causing neurovascular compression after revision THA. Clinicians should be aware of intrapelvic pseudotumor as a possible cause of limb swelling and neuropathy, and that debulking of the mass is a potential treatment option in the setting of well-fixed implants.

Management of Complex Pelvic Fracture with Associated Both Column Acetabular Fracture Judet-Letournel Type and a Coccygeal Fracture in a Severe Polytrauma Patient

Comprehensive emergency managements and early stabilization are pivotal upon treating complex pelvic and acetabular fractures. A thorough operative strategy is required to determine the best operative approach based on the patient’s general condition, available facilities, and surgeon preferences in such complex fracture configuration. Advanced technique of the fixation is necessary during a skillful execution of surgery in order to achieve good treatment results. An 18-years-old female crushed by a bus upon crossing street, presented with hypovolemic shock with ISS polytrauma score 50 consisting of right acetabular associated both column fracture, bilateral pelvic fracture anteroposterior compression type 3, and coccygeal fracture with bilateral drop foot. She underwent emergency laparotomy, had her ovary, bladder, and intestine primarily sutured, and then we immobilized the pelvic using anterior frame external fixator, which was maintained for 6 days. Upon stable condition, we performed right ilioinguinal approach and modified Stoppa with lateral window for the left side, while Kocher-Langenbeck technique was used to approach the posterior acetabular column. Postoperative radiology showed an adequate internal fixation in both right acetabular columns, successful reconstruction of pelvic ring which was fixated the left ischium, left superior and inferior pubic rami, and full restoration of left sacroiliac joint disruption. Majeed pelvic outcome score was 54, while Hannover pelvic outcome score was good and the patient was able to sit without pain 2 months postoperative. Management of complex pelvic-acetabular-coccygeal fracture requires a holistic chain of treatment by emphasizing the prompt emergency management, accurate preoperative planning, and excellent execution of reconstructive surgical strategy to achieve satisfactory outcome.

Treatment sequence of combined pelvic injury, consisted of upper pubic ramus fracture, sacroiliac joint dislocation with open book injury, using Stoppa approach

Among pelvic serious injuries is the so-called “open book” injury of the pelvis, with Sacroiliac Joint Disruption (SIJD) in combination with upper pubic ramus or anterior column fracture, contralateral or ipsilateral, or both. This combination of pelvic injury could be classified according Young and Burgess classification as LCIII or CM type (Combined Mechanism) and as 61-B3.1 61-B3.2 following AO/OTA classification. Specifically, the upper pubic ramus fracture can be classified according to Nakatani classification as type I medial of the foramen, type II within the foramen and type III lateral to the foramen. The difficulty to deal with these fractures is how to close and reduct the pubic symphysis in mechanically stable way since there is fracture in one or both the upper pubic ramus. The existence of these fractured elements, in this type of pelvis injury allow a lot of degrees of freedom which must be managed from the surgeon in the proper sequence. The incision and the approach are also mandatory for successfully treating these lesions. Anterior Intrapelvic Approach (AIP) or Stoppa approach in conjunction with the first window of ilioinguinal approach is the most appropriate surgical exposure for reduction and fixation.

Treatment of anterior column posterior hemitransverse fracture with supra-ilioinguinal approach

Objective To report the feasibility and effect of the supra-ilioinguinal approach for treatment of anterior posterior hemitransverse fracture of the acetabulum. Methods Nineteen consecutive patients who underwent treatment for an anterior column posterior hemitransverse fracture of the acetabulum from January 2013 to June 2018 were retrospectively analyzed. All patients underwent treatment by the single supra-ilioinguinal approach with at least 1 year of follow-up. Results The mean time to surgery, operative time, incision length, and blood loss were 10.2 ± 3.8 days, 157 ± 125 minutes, 10.2 ± 0.6 cm, and 876 ± 234 mL, respectively. According to the Matta scoring system, the reduction quality was excellent in 13 patients, good in 6, and poor in 0. According to the Merle d'Aubigné scoring system, the outcome at the last follow-up was excellent in 12 patients, good in 5, fair in 1, and poor in 1. Postoperative complications occurred in three patients (deep vein thrombosis in one, lateral femoral cutaneous nerve injury in one, and both complications in one). Conclusions Use of the supra-ilioinguinal approach for treatment of anterior column posterior hemitransverse fracture of the acetabulum produced excellent clinical results because of the direct visualization of the anterior column and quadrilateral plate.

Risk factors for complications following pelvic ring and acetabular fractures: A retrospective analysis at an urban level 1 trauma center

Background: Pelvic ring and acetabular fractures are some of the most morbid in orthopedic trauma. They commonly require large exposures for fixation and are associated with significant morbidity and mortality. This study attempts to identify risk factors for complications following operative fixation of pelvic injuries. Methods: 126 patients treated for pelvic injuries were reviewed retrospectively. Demographics, procedure characteristics, and outcomes were recorded. Variables associated with complications were analyzed using logistic regression analysis. Results: Complications occurred in 12 patients. Higher BMI, longer length of stay, and ilioinguinal approach were significantly associated with increased infection risk. Co-morbid heart disease and concurrent smoking status showed a trend for increased infection risk. Higher BMI and ilioinguinal approach were significantly associated with an increased likelihood of re-operation. Positive psychiatric history and Medicaid payer status showed a trend toward higher reoperation risk. Conclusion: Knowledge of these risk factors can help guide management and predict outcomes following pelvic fracture fixation.
