RESUMO
INTRODUCTION: The impact of obesity on the incidence of blunt pelvic fractures in adults is unclear, and adolescents may have an increased risk of fracture due to variable bone mineral density and leptin levels. Increased subcutaneous adipose tissue may provide protection, though the association between obesity and pelvic fractures in adolescents has not been studied. This study hypothesized that obese adolescents (OAs) presenting after motor vehicle collision (MVC) have a higher rate of pelvic fractures, and OAs with such fractures have a higher associated risk of complications and mortality compared to non-OAs. METHODS: The 2017-2019 Trauma Quality Improvement Program database was queried for adolescents (12-16 y old) presenting after MVC. The primary outcome was a pelvic fracture. Adolescents with a body mass index ≥30 (OA) were compared to adolescents with a body mass index <30 (non-OA). Subgroup analyses for high-risk and low-risk MVCs were performed. Multivariable logistic regression analyses were also performed adjusting for age and sex. RESULTS: From 22,610 MVCs, 3325 (14.7%) included OAs. The observed rate of pelvic fracture was similar between all OA and non-OA MVCs (10.2% versus 9.4%, P = 0.16), as well as subanalyses of minor or high-risk MVC (both P > 0.05). OAs presenting with a pelvic fracture after high-risk MVC had a similar risk of complications, pelvic surgery, and mortality compared to non-OAs (all P > 0.05). However, OAs with a pelvic fracture after minor MVC had a higher associated risk of complications (OR 2.27, CI 1.10-4.69, P = 0.03), but a similar risk of requiring pelvic surgery, and mortality (all P > 0.05). CONCLUSIONS: This national analysis found a similar observed incidence of pelvic fractures for OAs versus non-OAs involved in an MVC, including subanalyses of minor and high-risk MVC. Furthermore, there was no difference in the associated risk of morbidity and mortality except for OAs involved in a minor MVC had a higher risk of complication.

OBJECTIVE: To digitally measure the fixation trajectory of anatomical plates used in the combined reduction of quadrilateral acetabular fractures via the posterior approach, and to develop anatomical plates that align with the characteristics of the pelvis in the Chinese population. METHODS: Pelvic computed tomography (CT) data from 102 adult patients were collected at the Affiliated Hospital of Zunyi Medical University. This group included 51 males and 51 females, aged between 20 and 60 years. Using Mimics software (version 21.0), a three-dimensional model of each pelvic data point was reconstructed. The fixation path for the combined reset anatomical steel plate was drawn, where the curves on the fixation path were approximated as arcs. The radius of curvature and length of these curves were measured, and an anatomical steel plate was designed to best fit the pelvic structure. RESULTS: The combined anatomical reduction plate fixation system for quadrilateral acetabular fractures using a posterior approach consisted of two parts: a locking plate and a reduction plate. The posterior wall region (r2), ischial region (r3), quadrilateral region (r4), and bending region (r5), and the total length of the reduction plate were significantly smaller in females (P < 0.05). Similarly, the posterior wall region (R3), distal posterior wall region (R4), and the total length of the locking plate were significantly smaller in females (P < 0.05). Additionally, the anterior superior iliac spine side (r1) and the total length of the T-shaped auxiliary plate were significantly smaller in females (P < 0.05). The bending angle (< A) was also significantly smaller in females (P < 0.05). CONCLUSIONS: The pelvic surface structure is irregular and varies greatly among individuals.Compared to the traditional steel plate, The combined reduction anatomical plate designed in this study demonstrated high precision and improved conformity to the anatomical structure of the pelvis.

BACKGROUND: Bilateral acetabular fracture is a very rare presentation among the trauma patients, as the pattern and the degree of the forces required to fracture both acetabula is very unique. The primary purpose of this study is to report a series of adult patients presenting with post-traumatic bilateral acetabular fracture without any history of pathological or metabolic bone disease. PATIENTS AND METHODS: In this retrospective study, 18 cases of traumatic bilateral acetabular fracture were included. There was predominance of both column (four patients on left and six on right) followed by anterior column (two patients left and four on right) and posterior wall (three patients left and right). They were treated surgically through open reduction and internal fixation. All cases were followed up for at least 13 months. Matta's criteria were used for radiological evaluation on plain radiographs. Functional outcome was evaluated using the Merle d'Aubigne and postel score at final follow-up. RESULTS: No patients were lost during the follow-up period; there was one case of surgical site infection. There were three cases of postoperative osteoarthritis, one case of heterotrophic ossification, one case of persistent sciatic nerve palsy and one case of lateral femoral cutaneous nerve palsy. The radiological evaluation according to Matta's criteria revealed anatomic reduction in 12 patients, imperfect reduction in three patients while other three patients had poor reduction. According to modified Merle d'Aubigne and Postel score, 10 cases were rated as excellent, five cases as good and three cases presented fair (one case) to poor (two cases) results. CONCLUSION: We report an unusual case series of bilateral acetabular fracture successfully managed surgically with good clinical outcome. With the increasing incidence of route traffic accidents, such cases would probably be recurrent in the upcoming years.

PURPOSE: To explore the epidemiological trends in acetabular fracture and report the mid-term to long-term clinical outcomes of the elderly treated with operation. METHODS: Retrospective study. Patients aged ≥ 14 years with operative treatment of the Acetabular fracture from Jan 2010 to Dec 2019 at a level-1 trauma centre were identified to analyze the epidemiological trends, and the difference in fracture patterns between young and elderly patients (≥ 60 years old) were compared. The elderly patients were followed up to evaluate their clinical outcomes and satisfaction degree (worst to best: 0 to10). The patients were divided into the 2010-2014 group and the 2015-2019 group according to the year of admission, and the clinical outcomes of the two groups were compared to verify the stability from mid-term to long-term after surgery for acetabular fracture. RESULTS: A total of 1024 patients (mean age 43.35 years, range 14-86 years) with acetabular fractures received operative treatment in this decade. The mean age of the acetabular fracture patients increased from 41.1 years to 47.7 years, and the proportion of elderly patients increased from 5.7% to 24.0%, with some volatility. The ratio of male to female decreased year by year, and the proportion of female patients increased with age. And the anterior fracture patterns were more common in the elderly patients compared to the young patients (P < 0.001). 118 elderly patients (82 males, 36 females; mean age 66.91 years, range 60-86 years) were followed-up (mean 77.4 months, range 35-152 months). The overall mortality rate of the elderly patients was 7.69% (9/118). The Harris hip score of those alive patients was 90.41 ± 12.91 points (excellent and good rate 84.4%). 87 patients completed the SF-12 with a normal HRQoL (PCS 50.49 ± 8.88 points; MCS 55.66 ± 8.86 points). 90.8% of the patients achieved a satisfaction score of 9 or higher. And there was no significant difference in clinical outcomes between the 2010-2014 group and the 2015-2019 group (P > 0.05). CONCLUSIONS: In conclusion, acetabular fractures presented an obvious ageing trend in China, and the fracture patterns of the elderly patients differed from those in the young patients. Operative treatment for elderly acetabular fractures yielded satisfactory and persistent clinical outcomes from mid-term to long-term clinical.

INTRODUCTION: Various surgical techniques have been proposed to manage acetabular fractures involving both columns with posterior wall displacement. However, the optimal surgical approach to achieve satisfactory reduction quality remains controversial. MATERIALS AND METHODS: This retrospective study evaluated 34 patients with fractures who were treated at a single medical institution. The patients were divided into two groups according to the ventral/dorsal surgical approach employed: simultaneous (SI) and sequential (SE). Perioperative parameters, as well as radiological and functional outcomes, were analyzed and compared between the two groups. RESULTS: The SI and SE groups comprised 9 and 23 out of the 34 patients, respectively. The SI group exhibited a significantly shorter surgical time and lower estimated blood loss than the SE group (p = 0.04 and 0.03, respectively). The quality of reductions of the anterior and posterior columns was similar between the two groups; however, superior reduction in the fracture gap of the posterior wall was observed in the SI group, as revealed by axial and coronal computed tomography scans. CONCLUSIONS: A simultaneous ventral and dorsal approach through the pararectus and the modified Gibson approach confer clinical advantages in reducing the fracture gap, surgical time, and intraoperative blood loss when managing acetabular fractures involving both columns and a displaced posterior wall. Therefore, these surgical approaches may be considered to be optimal for achieving satisfactory reduction quality in such fractures.

BACKGROUND: Acute total hip arthroplasty has gained increasing popularity in the treatment of complex acetabular fractures in elderly patients, but the biomechanical evidence is lacking. Therefore, we measured the primary stability to evaluate whether acute total hip arthroplasty using a multi-hole acetabular cup and posterior column plating through a single K-L approach can safely be used for treating complexed acetabular fractures in the elderly. METHODS: In 18 composite osteoporotic hemipelves, T-type acetabular fractures were treated in three ways: CSP (Cup with acetabular screws augmentation combined with posterior plate) group, CP (Cup without acetabular screw combined with posterior plate) group and CSPA (Cup with acetabular screws combined with posterior plate and anterior plate) group. Each specimen was dynamically loaded (300 to 1700 N, 1 Hz). Primary stability of the acetabular cup and fracture gap was evaluated by 3-dimensional (3D) micromotions. RESULTS: No significant differences in the 3D-micromotions were observed among the CSP, CP and CSPA groups except the test point on the anterior column of the acetabulum in the CP scenario (CSP 49.33 ± 21.08 µm vs. CP 224.83 ± 52.29 µm, p < 0.001; CSPA 45.50 ± 12.16 µm vs. CP 224.83 ± 52.29 µm, p < 0.001). No significant differences in the fracture gap displacement on the posterior column of acetabulum were observed among the CSP, CP and CSPA groups. CONCLUSION: Our results show, that acute total hip arthroplasty using a multi-hole cup with acetabular screws and posterior column plating through single a K-L approach offers good primary stability to allow good osseous integration for treating complex acetabular fractures in the elderly. Furthermore, it also provides good fracture gap displacement on the posterior column.
RESUMO
The incidence of geriatric acetabular fractures has shown a sharp increase in the last decades. The majority of patients are male, which is different to other osteoporotic fractures. The typical pathomechanism generally differs from acetabular fractures in young patients regarding both the direction and the amount of force transmission to the acetabulum via the femoral head. Geriatric fractures very frequently involve anterior structures of the acetabulum, while the posterior wall is less frequently involved. The anterior column and posterior hemitransverse (ACPHT) fracture is the most common fracture type. Superomedial dome impactions (gull sign) are a frequent feature in geriatric acetabular fractures as well. Treatment options include nonoperative treatment, internal fixation and arthoplasty. Nonoperative treatment includes rapid mobilisation and full weighbearing under analgesia and is advisable in non- or minimally displaced fractures without subluxation of the hip joint and without positive gull sign. Open reduction and internal fixation of geriatric acetabular fractures leads to good or excellent results, if anatomic reduction is achieved intraoperatively and loss of reduction does not occur postoperatively. Primary arthroplasty of geriatric acetabular fractures is a treatment option, which does not require anatomic reduction, allows for immediate postoperative full weightbearing and obviates several complications, which are associated with internal fixation. The major issue is the fixation of the acetabular cup in the fractured bone. Primary cups, reinforcement rings or a combination of arthroplasty and internal fixation may be applied depending on the acetabular fracture type.
RESUMO
Screw fixation of acetabular column fractures is a well-established alternative option to plate fixation providing comparable biomechanical strength and requiring less surgical exposure. For displaced acetabular fractures involving both columns open reduction and plate fixation of one column in combination with a column-crossing screw fixation of the opposite column via a single approach is a viable treatment option. Preoperative planning of posterior column screws (PCS) via an anterior approach is mandatory to assess the eligibility of the fracture for this technique and to plan the entry point and the screw trajectory. The intraoperative application requires fluoroscopic guidance using several views. A single view showing an extraarticular screw position is adequate to rule out hip joint penetration. The fluoroscopic assessment of cortical perforation of the posterior column requires several oblique views such as lateral oblique views, obturator oblique views and axial views of the posterior column or alternatively intraoperative CT scans. The application of PCS via an anterior approach is a technically demanding procedure, that allows for a relevant reduction of approach-related morbidity, surgical time and blood loss by using a single approach.
RESUMO
PURPOSE: While the effects of tranexamic acid (TXA) use on transfusion rates after acetabular fracture surgery are unclear, previous evidence suggests that holding deep vein thrombosis (DVT) chemoprophylaxis may improve TXA efficacy. This study examines whether holding DVT chemoprophylaxis in patients receiving TXA affects intraoperative and postoperative transfusion rates in acetabular fracture surgery. METHODS: We reviewed electronic medical records (EMR) of 305 patients who underwent open reduction and internal fixation of acetabular fractures (AO/OTA 62) and stratified patients per the following perioperative treatment: (1) no intraoperative TXA (noTXA), (2) intraoperative TXA and no preoperative DVT prophylaxis (opTXA/noDVTP), or (3) intraoperative TXA and preoperative DVT prophylaxis (opTXA/opDVTP). The primary outcomes were need for intraoperative or postoperative transfusion. Risk factors for each primary outcome were assessed using multivariable regression. RESULTS: Intraoperative or postoperative transfusion rates did not significantly differ between opTXA/opDVTP and opTXA/noDVTP groups (46.2% vs. 36%, p = 0.463; 15.4% vs. 28%, p = 0.181). Median units transfused did not differ between groups (2 ± 1 vs. 2 ± 1, p = 0.515; 2 ± 1 vs. 2 ± 0, p = 0.099). There was no association between preoperative DVT chemoprophylaxis and TXA with intraoperative or postoperative transfusions. EBL, preoperative hematocrit, and IV fluids were associated with intraoperative transfusions; age and Charlson Comorbidity Index (CCI) were associated with postoperative transfusions. CONCLUSION: Our findings suggest holding DVT prophylaxis did not alter the effect of TXA on blood loss or need for transfusion.

INTRODUCTION: Unstable acetabular fracture remains a complex fracture that requires technically demanding surgery for orthopedic surgeons. Quadrilateral plate (QP) fractures of the acetabulum are a challenging group of acetabular fractures to manage. However, the literature regarding the management of these injuries are limited. The QP is a relatively thin medial wall of the acetabulum and intra-articular; thus, anatomical reduction and stable fixation are required for satisfactory outcome. This study aims to determine the functional, radiological, and quality of life outcome of unstable acetabular fracture with QP involvement. METHODS: This was a retrospective cohort study conducted at Cipto Mangunkusumo General Hospital during the period of 2010-2020. Patients with unstable acetabular fractures with and without QP involvement were included in this study. They were followed up postoperatively at 1, 6, and 12 months. Functional outcome was assessed using the Harris Hip Score (HHS), Merle D'Aubigne, and Oxford Hip Score (OHS); while radiology outcome was assessed using Matta Outcome Grading; and quality of life was assessed using the SF-36. RESULTS: This study involved 53 subjects with a median age was 29 (18-75) years of age. Twenty-eight (52.8%) subjects had unstable acetabular fracture with QP involvement. Twenty-five (47.2%) subjects had unstable acetabular fracture without QP involvement. Twenty-five (47.2%) subjects were fixed using quadrilateral hook plate, 3 (5.7%) with infrapectineal plate, 10 (18.8%) with posterior column plate, and 15 (28.3%) with suprapectineal plate. The median intraoperative bleeding in those with unstable acetabular fracture with QP involvement was 600 (300-4000) ml, which was higher than those without QP involvement (400 [100-1700] ml). Those with QP involvement achieved anatomical reduction in 20 (71.4%) subjects. Whereas, the subjects without QP involvement achieved anatomical reduction 23 patients (92%). Subjects with QP involvement had significantly lower functional, radiological, and quality of life outcomes compared to those without quadrilateral plate involvement based on Harris Hip Score (p = 0.046), Merle D'Aubigne (0.001), Oxford Hip Score (0.001), Matta Outcome Grading (0.004), and SF-36 (0.001). Patients with quadrilateral hook plate showed no significant functional, and radiological outcome difference compared to patients with infrapectineal plate based on Harris Hip Score (p = 0.582), Merle D'Aubigne (0.698), Oxford Hip Score (1.000), and Matta Outcome Grading (1.000). In addition, we also found no significant functional, radiological, and quality of life outcome difference between posterior column plate and suprapectineal plate group based on Harris Hip Score (p = 0.200), Merle D'Aubigne (0.643), Oxford Hip Score (0.316), Matta Outcome Grading (1.000), and SF-36 (0.600). CONCLUSIONS: Patients with unstable acetabular fracture with quadrilateral plate involvement subject had significantly lower functional, radiological, and quality of life outcomes compared to those without quadrilateral plate involvement. Both quadrilateral hook and infrapectineal plates demonstrated non-significant functional and radiological outcomes difference. Posterior column plate also resulted in the same functional, radiological, and quality of life outcome compared with suprapectineal fixation.

PURPOSE: Acetabular fracture fixation can be challenging, especially in the elderly. Open reduction and internal fixation (ORIF) alone may not allow for early weight bearing and is associated with a high rate of secondary osteoarthritis; therefore, a combined hip procedure (CHP) or ORIF with acute total hip arthroplasty, may be beneficial in this population. The objective of this study was to perform a systematic review of all reported cases of CHP. METHODS: PubMed, Embase, Scopus, and Cochrane databases were searched for studies analyzing acetabular fractures in the elderly managed with a combined hip procedure (CHP). The research was performed following the PRISMA guidelines. The included studies' methodological quality was evaluated using the MINORS score. The present study was registered on PROSPERO. RESULTS: Eleven clinical studies were included in the final analysis. The mean age was 74.4 (63.2-78) years. Low-energy trauma was the most common mechanism of injury (64%). The most prevalent fracture pattern was the anterior column and posterior hemitransverse (ACPHT) (30.6%). The Kocher-Langenbeck approach was preferred for ORIF of posterior fractures and hip arthroplasty. The ilioinguinal approach and modified Stoppa were generally used for anterior fractures. The overall complication rate was 12.2%, and hip dislocation was the most frequent cause of reoperation (4.4%). The average Harris Hip Score reported postoperatively was 81.6 points, which was considered "good." CONCLUSIONS: CHP is a safe treatment for elderly acetabular fractures with an acceptable complication and reoperation rate that results in good clinical outcomes. LEVEL OF EVIDENCE: Level of evidence IV.

Incidence of pelvic and acetabular fracture is increasing in Europe. From 2007 to 2014 in the USA, this study found an age-adjusted incidence of 198 and 40 fractures/100,000/year, respectively, much higher than what has been described before. Incidence remained steady over that period and only a small increase in incidence of pelvic fracture in men was identified. PURPOSE: To determine the incidence of pelvic ring and acetabular fractures in the USA over the period 2007-2014 and to examine trends over time. METHODS: Retrospective population-based observational study using data from the Nationwide Emergency Department Sample (NEDS), a 20% stratified all-payer sample of US hospital-based emergency departments (EDs). All patients seen in the ED and diagnosed with pelvic/acetabular fracture from 2007 to 2014 were included. The primary outcome was age-adjusted incidence of pelvic and acetabular fractures per 100,000 persons/years. Secondary outcomes included incidence stratified by age and sex, patient- and hospital-related characteristics, and ED procedures. Tests for linear trends were used to determine if there were statistically significant differences by sex and age groups over time. RESULTS: The age-adjusted incidence of pelvic fracture was 198 fractures/100,000/year, 323 in women and 114 in men. The age-adjusted incidence of acetabular fracture was 40 fractures/100,000/year, 36 in women and 51 in men. A small increase in the age-adjusted incidence of pelvic fracture in men was the only significant trend observed during the study time (p = 0.03). Over that period, the mean age of patients at presentation increased, as well as their number of comorbidities and associated fragility fractures, and they were more often sent home or to nursing facilities. CONCLUSIONS: When considering all patients coming to the ED, not only those admitted to the hospital, adjusted incidence of pelvic and acetabular fracture is much higher than what has been described before. Contrarily to the global increase seen in other countries, incidence of pelvic and acetabular fractures dropped in the USA from 2007 to 2014 and only a small increase in age-adjusted incidence of pelvic fracture in men was identified.

The anterior ilioinguinal and the posterior Kocher-Langenbeck approach have long been the standard surgical approaches to the acetabulum. The last decade has witnessed the development of so-called intrapelvic approaches for anterior pathologies because they provide better exposure of the quadrilateral plate. Currently, the modified Stoppa approach and the pararectus approach are frequently used by surgeons for the treatment of acetabular fractures. We investigated an even more direct access to the entire anterior column and the quadrilateral plate via the abdominal wall muscles, between the incisions for the ilioinguinal and the pararectus approach.After intensive study of anatomic specimens, a cadaver dissection was performed prior to clinical application. The approach was then used in 20 patients who were assessed retrospectively.Postoperative CT scans showed that, according to the Matta scoring system, the quality of fracture reduction was "anatomical" (≤ 1 mm) in 12 (60%), "imperfect" (2-3 mm) in four (20%), and "poor" (> 3 mm) in four (20%) patients. Numerous minor complications were observed; the majority of these had resolved at the time of discharge.In conclusion, the anterior transmuscular intrapelvic approach (ATI) is a safe and effective alternative to the ilioinguinal and pararectal approaches, and may be regarded as an evolutionary advancement of traditional procedures.

BACKGROUND: Surgical treatment of pelvic and acetabular fractures is an advanced intervention with a high risk of subsequent complications. These patients are often polytrauma patients with multiple injuries in several organ systems. The optimal timing for the definitive surgery of these fractures has been debated. The primary aim of this study was to investigate the influence of timing of definitive surgery on the rate of unplanned reoperations. Secondary aims included its influence on the occurrence of adverse events and mortality. METHODS: All patients from 18 years with a surgically treated pelvic or acetabular fracture operated at the Karolinska University Hospital in Sweden during 2010 to 2019 were identified and included. Data was collected through review of medical records and radiographs. Logistic regression analysis was performed to evaluate factors associated with unplanned reoperations and other adverse events. RESULTS: A total of 419 patients with definitive surgical treatment within 1 month of a pelvic (n = 191, 46%) or an acetabular (n = 228, 54%) fracture were included. The majority of the patients were males (n = 298, 71%) and the mean (SD, range) age was 53.3 (19, 18-94) years. A total of 194 (46%) patients had their surgery within 72 h (early surgery group), and 225 (54%) later than 72 h (late surgery group) after the injury. 95 patients (23%) had an unplanned reoperation. There was no difference in the reoperation rate between early (n = 44, 23%) and late (n = 51, 23%) surgery group (p = 1.0). A total of 148 patients (35%) had any kind of adverse event not requiring reoperation. The rate was 32% (n = 62) in the early, and 38% (n = 86) in the late surgery group (p = 0.2). When adjusting for relevant factors in regression analyses, no associations were found that increased the risk for reoperation or other adverse events. The 30-day mortality was 2.1% (n = 4) for the early and 2.2% (n = 5) for the late surgery group (p = 1.0). The 1-year mortality was 4.1% (n = 8) for the early and 7.6% (n = 17) for the late surgery group (p = 0.2). CONCLUSIONS: Early (within 72 h) definitive surgery of patients with pelvic or acetabular fractures seems safe with regard to risk for reoperation, other adverse events and mortality.

BACKGROUND: The predictors of post-traumatic osteoarthritis (PTOA) in patients with transverse acetabular fractures (TAFs) following open reduction internal fixation (ORIF) remain unclear. This study aimed to investigate the risk factors for PTOA in TAFs after ORIF. METHODS: Data of TAF patients receiving ORIF were collected from January 2012 and February 2021. Patients suffered PTOA were classified as the osteoarthritis group (OG), while those without PTOA were classified as the non- osteoarthritis group (NG) with a minimum follow-up of 2 years. PTOA was diagnosed according to Tönnis OA classification during the period of follow-up. Univariate analysis, logistic regression analysis, and receiver operating characteristic (ROC) curve analyses were used to evaluate demographics, injury-related characteristics, perioperative and post-discharge information. RESULTS: Three hundred and eleven TAF patients were analyzed in this study, including 261 males and 50 females, with a mean age of 40.4 years (range 18 to 64 years). The incidence of PTOA was 29.6% (92 of 311) during the mean follow-up of 36.8 months (range 24 to 70 months). Several factors of PTOA were found using univariate analysis, including transverse fracture associated with posterior wall acetabular fracture (TPW-AF, p = 0.002), acetabular roof fracture (ARF, p = 0.001), femoral head lesion (FHL, p = 0.016), longer time from injury to surgery (TIS, pï¼0.001) and physical work after surgery (PWAS, pï¼0.001). Logistic regression analysis showed that TPW-AF (p = 0.007, OR = 2.610, 95%CI: 1.302-5.232), ARF (p = 0.001, OR = 2.887, 95%CI: 1.512-5.512), FHL (p = 0.005, OR = 2.302, 95%CI: 1.283-4.131), TIS (p<0.0001, OR = 1.294, 95%CI: 1.192-1.405) and PWAS (p<0.0001, 3.198, 95%CI: 1.765-5.797) were independent risk factors of PTOA. Furthermore, ROC curve analysis indicated 11.5 days as the cut-off values to predict PTOA. CONCLUSIONS: Our findings identified that TPW-AF, ARF, FHL, TIS and PWAS were independent risk factors for PTOA in patients with TAFs following ORIF. It can help orthopedic surgeons to take early individualized interventions to reduce its incidence.

BACKGROUND: Total hip arthroplasty (THA) for the treatment of acute acetabular fractures may be indicated where there is high risk for failure of open reduction and internal fixation. This study aimed to determine risks of revision and rates of major complications of THA for acute acetabular fractures. METHODS: A retrospective review was performed (all-claims data files of a large national database) by querying International Classification of Disease, 10th revision procedure codes for THA within 14 days of acetabular fracture. We identified all-cause revision and surgical complications including dislocations, mechanical failures (loosenings or broken prostheses), infections, as well as medical complications. Demographic data collected included age, sex, obesity, and Charlson Comorbidity Index (CCI). Multivariate analyses evaluated the association of revision and major surgical complications after adjusting for demographic characteristics and comorbidities. We identified 956 THAs for the treatment of acute acetabular fracture from 2015 to 2020. Of all acute acetabular fractures treated with THA, 241 were concomitant with open reduction and internal fixation (ORIF), and 715 were THA-alone. RESULTS: All-cause revision risk was 18.2%, overall major surgical complication rate 26.9%, and medical complication rate was 13.2%. Women were associated with increased risk of revision (adjusted odds ratio (aOR) 1.8; confidence interval (CI) 1.3 to 2.6, P = .001), dislocation (aOR 2.0; CI 1.5 to 3.1, P < .001), mechanical complication (aOR 2.1; CI 1.4 to 3.2, P < .001), and infection (aOR 1.6; CI 1.0 to 2.5, P = .044). CONCLUSION: We noted risk of all-cause revision of 18.2%, overall major surgical complication rate of 26.9%, and overall major medical complication rate of 13.2% for THA as the treatment of acute acetabular fracture. We caution against broad expansion of THA for treatment of acute acetabular fractures. Furthermore, increased risks of revision and complications in women warrant additional investigation into patient and fracture characteristics that may contribute to this finding.

BACKGROUND: Intrapelvic hemorrhage following pelvic fractures, including pelvic ring and acetabular fractures, originates from the venous system and the fracture. Arterial injury often causes significant bleeding and hemodynamic instability. The superior gluteal artery (SGA) is a frequently injured artery in patients with pelvic fractures. This study investigated the incidence and pattern of SGA injuries associated with pelvic fractures. METHODS: We retrospectively reviewed the medical records of patients with pelvic fractures who visited our institution between January 2016 and April 2022. Patients who underwent angiography for suspected arterial injury and SGA embolization were identified. Furthermore, the demographics and patterns of pelvic fractures were evaluated. RESULTS: In total, 2042 patients with pelvic fractures visited our trauma emergency department and 498 patients (24.4%) underwent embolization for arterial injuries. Of these, 30 patients (1.5% of the total and 6.0% of the patients who underwent procedures) received embolization therapy of the main trunk of the SGA. The mean age of patients was 51.2 (23-85 years), and the injury mechanisms were all high-energy injuries. There were 19 pelvic ring injuries, eight acetabular fractures, and three combined injuries. Acetabular fractures involved mostly both columns. The three combined injuries were lateral compression involving both columns, vertical shear involving both columns, and lateral compression with T-type fractures. Twelve (40.0%) occurred through the sciatic notch of different patterns. CONCLUSIONS: SGA injury occurred in 1.5% of all pelvic fractures and was identified in 6% of patients receiving embolization. SGA injury occurs through various injury mechanisms and fracture patterns, even in the absence of a fracture in the sciatic notch. However, no conclusions could be drawn in this study on the association between SGA injuries, injury mechanisms, and fracture patterns. Since the prediction of SGA injury by fracture pattern is limited, angiography should be performed regardless of fracture pattern when an injury is suspected.
RESUMO
PURPOSE: This study aims to evaluate the efficacy of single pararectus approach in patients confirmed with acetabular fracture involving anterior and posterior columns. METHODS: A total of 58 patients confirmed with acetabular fracture involving anterior and posterior columns and treated at our hospital between January 2015 and January 2020 were retrospectively analyzed. A single pararectus approach was applied for all patients. Routine X-rays were performed at follow-up of one, three, six, 12, and 18 months, and three-dimensional CT scans were added at six and 18 months. Fracture reduction quality was assessed using the Matta score system, and functional assessment used the Modified Merle D'Aubigné and Postel score system. Post-operative complications, including fat liquefaction and deep vein thrombosis, were recorded and analyzed. RESULTS: The median operation time was 186 min while the intra-operative blood loss was 421 mL. The rate of good-to-excellent reduction was 94.8%, and the rate of good-to-excellent hip function score reached 93.1%. Seven patients presented with post-operative complications, including three intra-operative small vascular injuries, two peritoneal small perforations, one fat liquefaction, and one deep vein thrombosis. CONCLUSION: Using a single pararectus approach is convenient and effective for treating acetabular fracture involving anterior and posterior columns, especially those involving the quadrilateral area.

PURPOSE: Acetabular fractures are associated to an increased risk of subsequent hip osteoarthritis. The only available score for post-operative reduction assessment in acetabular fractures (Matta's score) is x-ray based. CT-scan was shown superior to X-rays in post-operative reduction assessment. We aim to describe a CT-scan-based post-operative reduction score in acetabular fractures and evaluate its accuracy and reproducibility. METHODS: This is a retrospective study that includes 138 patients who underwent surgery for an acetabular fracture in our tertiary referral centre with a mean follow-up of 104.39±42.2 months. The post-operative CT-scan was reviewed and residual displacement (maximum gap and step) measured by three independent observers. The association between the occurrence of THA and the CT-scan measurements was evaluated. This led to a new prognostic score. The interobserver reliability and accuracy of this score were calculated. RESULTS: Interobserver reproducibility for the residual maximal gap was 0.82 (95% CI [0.70-0.89]) and 0.61 (95% CI [0.52-0.70]) for the residual maximal step displacement measurements. We created a score from a logistic regression model, attributing 1 point for every 1 mm of residual maximal step displacement and 1 point for every 2 mm of residual maximal gap displacement. The interobserver reproducibility of this score was 0.78 (95% CI [0.71-0.84]), and its AUC was 0.79 (95% CI [0.69-0.88]). CONCLUSION: This is the first CT-scan-based score for the assessment of residual displacement of a surgically treated acetabular fracture. It shows good interobserver reproducibility and accuracy in predicting the risk for secondary THA. It should be regularly used per-operatively (if per-operative 3D imaging is available) and post-operatively to predict the prognosis.

PURPOSE: The American Academy of Orthopaedic Surgeons does not currently provide clinical practice guidelines for management of PAF. Accordingly, this article aims to review and consolidate the relevant historical and recent literature in important topics pertaining to perioperative management of PAF. METHODS: A thorough literature review using PubMed, Cochrane and Embase databases was performed to assess preoperative, intraoperative and postoperative management of PAF fracture. Topics reviewed included: time from injury to definitive fixation, the role of inferior vena cava filters (IVCF), tranexamic acid (TXA) use, intraopoperative cell salvage, incisional negative pressure wound therapy (NPWT), intraoperative antibiotic powder use, heterotopic ossification prophylaxis, and pre- and postoperative venous thromboembolism (VTE) prophylaxis. RESULTS: A total of 126 articles pertaining to the preoperative, intraoperative and postoperative management of PAF were reviewed. Articles reviewed by topic include 13 articles pertaining to time to fixation, 23 on IVCF use, 14 on VTE prophylaxis, 20 on TXA use, 10 on cell salvage, 10 on iNPWT 14 on intraoperative antibiotic powder and 20 on HO prophylaxis. An additional eight articles were reviewed to describe background information. Five articles provided information for two or more treatment modalities and were therefore included in multiple categories when tabulating the number of articles reviewed per topic. CONCLUSION: The literature supports the use of radiation therapy for HO prophylaxis, early (< 5 days from injury) surgical intervention and the routine use of intraoperative TXA. The literature does not support the routine use of iNPWT or IVCF. There is inadequate information to make a recommendation regarding the use of cell salvage and wound infiltration with antibiotic powder. While the routine use of chemical VTE prophylaxis is recommended, there is insufficient evidence to recommend the optimal agent and duration of therapy.
