Acetabular fractures potentially account for up to half of all pelvic fractures, while pelvic fractures potentially account for over one-tenth of all human bone fractures. This is the first biomechanical study to assess acetabular fracture fixation using plates versus cables in the presence of a total hip arthroplasty, as done for the elderly. In Phase 1, finite element (FE) models compared a standard plate method versus 3 cable methods for repairing an acetabular fracture (type: anterior column plus posterior hemi-transverse) subjected to a physiological-type compressive load of 2207N representing 3 x body weight for a 75kg person during walking...

The purpose of this study was to compare the accuracy of pin placement in patients with unstable pelvic fractures undergoing either iliac crest or supra-acetabular external fixation. A retrospective review was performed of computed tomography (CT) scans and injury characteristics for all patients presenting to a North Atlantic Treaty Organization Medical Treatment Facility with data entered into the Department of Defense Trauma Registry from January 2008 to October 2013 who underwent pelvic external fixation for unstable pelvic ring injuries...

Stabilization of pelvic ring injuries and certain acetabular fractures using percutaneous techniques is becoming increasingly more common. Intramedullary superior ramus screw fixation is beneficial in both injury types. While implants can be placed in an antegrade or retrograde direction, parasymphyseal ramus fractures benefit from retrograde implant insertion. In some patients, the parabolic osseous anatomy or obstructing soft tissues of the anterior pelvis or thigh can prevent appropriate hand and instrumentation positioning for appropriate retrograde ramus screw insertion through the entire osseous fixation pathway...

PURPOSE: To explore the diagnosis, treatment, and clinical prognosis of patients with both unstable pelvic fractures and concomitant acetabular fractures. MATERIAL AND METHODS: We retrospectively analyzed 21 cases of unstable pelvic fractures with concomitant acetabular fractures treated between January 2013 and December 2014. All 21 patients (18 males, 3 females), aged 43.5-55 years (range: 21-55 years), underwent surgery within four to 15 days (average = 6...

Objective To analyze the effects of the acetabular fracture index (AFI) and other factors on the functional outcome of patients with acetabular fractures involving the posterior wall. Methods Forty-eight patients who underwent surgery in our department were reviewed. According to the AFI, which indicates the percentage of remaining intact posterior acetabular arc, the patients were divided into Group A (AFI ≤ 25%, 11 patients), Group B (25% < AFI ≤ 50%, 23 patients), Group C (50% < AFI ≤ 75%, 7 patients), and Group D (75% < AFI ≤ 100%, 7 patients)...

The purpose of this study was to evaluate the results of open reduction and internal fixation in a large series of posterior wall fractures of the acetabulum and to identify the factors that affect the outcomes in this case series. One hundred twenty-one patients who had undergone open reduction and internal fixation of a fracture of the posterior wall of the acetabulum were assessed at a mean of 53 months (range, 24-163) after surgery. The functional outcome was evaluated with use of the modified Merle d'Aubigne scoring system, the Harris Hip Score (HHS), and the Short Form-36 Health Survey (SF-36) questionnaire...

INTRODUCTION: Quadrilateral plate fractures constitute one of the most challenging components of acetabular fractures. The objective of this study is to describe and evaluate the novel technique of buttress screw fixation of the quadrilateral plate component of the acetabular fractures. PATIENTS & METHODS: Forty cases of acetabular fracture with associated quadrilateral plate component were included in the study. Mean age was 35 years (range, 16-68years), with a mean follow-up 16...

The main goals of acetabular fracture management are to restore the congruity and stability of the hip joint. These goals are the same for all patients who have an acetabular fracture, regardless of the morphology or etiology of the fracture. Nevertheless, certain acetabular fracture types and several patient factors pose management challenges for surgeons. Therefore, surgeons who manage acetabular fractures must understand the distinctive features of acetabular fractures as well as the soft-tissue and patient-related factors that play a critical role in patient outcomes...

OBJECTIVE: Involvement of both columns in acetabular fractures is a common presentation; these fractures create a challenging situation for the surgeons in terms of understanding the dimensions of osseous injury and selection of surgical approach. The study was done with an objective to evaluate the efficacy of single posterior approach for acetabular fractures involving both columns directly reducing the posterior wall and column and indirectly reducing the anterior column. METHODS: An evaluation of 25 adult patients 18 male and 7 female presenting in the accident and emergency department of Khyber Teaching Hospital from December 2013 to June 2015 having acetabular fracture involving both the anterior and posterior column were included in this case series study...

INTRODUCTION: The role of proximal femur morphology to the development of certain proximal femur fracture types both femoral neck and trochanteric fractures has been observed. However, the relavance of acetabular morphology to the development of proximal femur fractures is not extensively questioned. Therefore the aim of the study was to determine whether there is a correlation between acetabular morphology and pathogenesis of 2 different hip fracture types after low energy trauma. METHOD: This retrospective study includes 60 cases (41 women, 19 men) with a proximal femoral fracture after a low energy trauma between July 2012 and December 2014...

Bilateral traumatic hip dislocations are extremely rare. Most of these are related to acetabular or proximal femoral fractures, consisting of complex lesions, and are rarely pure ligamentous injuries. Posterior dislocation is the most frequent. Some dislocations are accompanied by sciatic nerve palsy. The present case is a posterior bilateral hip dislocation with no other associated lesions, there are very few reports published with this clinical setting. The patient had good functional outcome.

INTRODUCTION: The Enterobacter cloacae is a microorganism found in the intestinal flora of the majority of animals, including humans. Primary infections caused by E. cloacae are rare in immunocompetent patients, but are very common in hospital settings in newborns and immunocompromised patients, and can be aggravated by the insurgence of antibiotic resistance. The incidence of periprosthetic hip infections is just below 2%. CASE PRESENTATION: A 76year old woman with multiple comorbidities underwent surgical implantation of intermediary total hip prosthesis of the left hip, in a different health facility, in February 2014, after the basicervical fracture of the upper femur extremity due to trauma...

INTRODUCTION: Road traffic accidents (RTAs) are the leading cause of trauma related mortality in Ireland. The penalty points system (PPS) was introduced in Ireland in 2002 to incentivise safer driving and reduce injury. Its early effect was studied previously(1) which concluded that there was a slight reduction in RTA related femoral shaft fractures (a sensitive indicator of high energy trauma) and a dramatic reduction in RTA related discharges. We hypothesized that over the following 14 years, the penalty points system might lose its effectiveness...

The purpose of this article is to evaluate the efficacy and feasibility of preoperative surgery with 3D printing-assisted internal fixation of complicated acetabular fractures. A retrospective case review was performed for the above surgical procedure. A 23-year-old man was confirmed by radiological examination to have fractures of multiple ribs, with hemopneumothorax and communicated fractures of the left acetabulum. According to the Letounel and Judet classification, T-shaped fracture involving posterior wall was diagnosed...

INTRODUCTION: Open reduction and internal fixation (ORIF) is standard care for most acetabular fractures. With increasing numbers of acetabular fractures in the elderly, the risk of revision surgery and conversion to total hip replacement (THR) is increasing. Alarmingly, about 20-25% of acetabular fractures in the elderly following ORIF needed revision and conversion to delayed THR. METHODS: Recently, prognostic factors have been identified, which correlate with an increased risk of worse outcomes following ORIF of acetabular fractures in the elderly patient...
