A-G Hue, R Gauthé, A-C Tobenas-Dujardin, A Vallée, J Mouton, F Dujardin
INTRODUCTION: Among the various options for internal fixation of acetabular fractures, the enlarged iliofemoral approach is less often used, being more invasive, although providing greater exposure enabling control of all components in complex fractures. Even so, the impact of its invasiveness has not been confirmed, and long-term results are not known. We therefore performed a retrospective study, aiming 1) to assess long-term functional outcome, and 2) to assess associated morbidity...

BACKGROUND: Cup malposition is a common cause of impingement, limitation of ROM, acceleration of bearing wear, liner fracture, and instability in THA. Previous studies of the safe zone based on plain radiographs have limitations inherent to measuring angles from two-dimensional projections. The current study uses CT to measure component position in stable and unstable hips to assess the presence of a safe zone for cup position in THA. QUESTIONS/PURPOSES: (1) Does acetabular component orientation, when measured on CT, differ in stable components and those revised for recurrent instability? (2) Do CT data support historic safe zone definitions for component orientation in THA? METHODS: We identified 34 hips that had undergone revision of the acetabulum for recurrent instability that also had a CT scan of the pelvis between August 2003 and February 2017...

This review aims to summarize the basic treatment principles of fractures according to their types and general management principles of special conditions including physeal fractures, multiple fractures, open fractures, and pathologic fractures in children. Definition of the fracture is needed for better understanding the injury mechanism, planning a proper treatment strategy, and estimating the prognosis. As the healing process is less complicated, remodeling capacity is higher and non-union is rare, the fractures in children are commonly treated by non-surgical methods...

BACKGROUND: Personal watercrafts (PWC) account for a disproportionate amount of water based injuries. Current literature suggests those with less PWC experience are more at risk for injury. Previous studies have not specifically evaluated the orthopedic implications of PWC usage or how various mechanisms of injury (MOI) contribute to different injury patterns. HYPOTHESIS: PWC injuries will frequently require orthopedic intervention. The presence of an orthopedic injury will result in increased injury severity score (ISS), hospital and intensive care unit (ICU) length-of-stay (LOS)...

BACKGROUND: The standard aftercare treatment in surgically treated trauma patients with fractures around or in a joint, known as (peri)- or intra-articular fractures of the lower extremities, is either non-weight bearing or partial weight bearing. We have developed an early permissive weight bearing post-surgery rehabilitation protocol in surgically treated patients with fractures of the lower extremities. In this proposal we want to compare our early permissive weight bearing protocol to the existing current non-weight bearing guidelines in a prospective comparative cohort study...

A 77-year-old man sustained an acetabular fracture after falling from a staircase and landing on his right side. He fractured the anterior column of his acetabulum and the quadrilateral plate. He underwent a single-stage open reduction and internal fixation of the fracture combined with a dual mobility total hip arthroplasty (THA). He sustained a traumatic hip dislocation 1 month postoperatively. Closed reduction was attempted at another hospital, and the femoral stem was pulled out. We believe this was caused by the polyliner being hitched either to the acetabular cup or in the soft tissues around the ilium...

BACKGROUND: Traumatic posterior hip dislocations in children and adolescents requires emergent closed reduction. Postreduction imaging is necessary to assess the concentricity of reduction and structural injuries to the hip. There is no a consensus for which imaging is a modality of choice in such condition. The purposes of this study are to describe magnetic resonance imaging (MRI) findings of traumatic posterior hip dislocations and to compare the effectiveness of MRI with computerized tomography (CT) in detecting structural abnormalities of the hip that impact patient management...

PURPOSE: This study aimed to evaluate the biomechanical stability of different fixation techniques for fractures of the acetabular posterior wall. The hypothesis was that a reconstruction plate, combined with compression screw fixation and a plate placed lateral to the screws, would achieve a higher peak load to failure and stiffness and reduced gapping during cycle loading than other fixation techniques. METHODS: A total of 24 Sawbone pelvis models were created with simulated fractures at the posterior wall of the acetabulum...

AIMS: Dislocation rates are reportedly lower in patients requiring proximal femoral hemiarthroplasty than for patients undergoing hip arthroplasty for neoplasia. Without acetabular replacement, pain due to acetabular wear necessitating revision surgery has been described. We aimed to determine whether wear of the native acetabulum following hemiarthroplasty necessitates revision surgery with secondary replacement of the acetabulum after proximal femoral replacement (PFR) for tumour reconstruction...

We present the case of a 13-year-old boy who sustained a locked central fracture dislocation of the right acetabulum following a bicycle fall. Immediate external reduction maneuvers under general anesthesia were unsuccessful due to intrapelvic entrapment of the femoral head. Open reduction internal fixation was achieved 48 hours later. After an initial satisfactory postoperative course, the patient ended up developing severe hip osteoarthritis 16 months after the procedure. The rarity of this injury in children is discussed, with its possible implications on joint congruity and potential growth injury...

OBJECTIVES: While osteoporosis has been shown to be a contributing factor in low energy fractures in the elderly, limited data exists regarding the correlation of bone mineral density (BMD) and T-Scores to mortality and failure of fracture fixation. This study seeks to determine the relationship between femoral neck BMD in elderly patients with typical geriatric fractures and mortality and fracture fixation failure using Quantitative Computed Tomography (QCT). MATERIALS AND METHODS: Patients over the age of 65 who sustained fractures of the proximal humerus, distal radius, pelvic ring, acetabulum, hip, proximal tibia, and ankle who also underwent a CT scan that included an uninjured femoral neck were retrospectively reviewed...

Atypical insufficiency fracture of the femur following prolonged bisphosphonate use is well described. Regardless of the cause, insufficiency fracture of the acetabulum is extremely rare, and no reports have described insufficiency fractures of the acetabulum that are associated with prolonged bisphosphonate use. This report demonstrates the possibility of insufficiency fracture at the acetabulum following long-term alendronate use and the necessity of particular care in managing insufficiency fractures in "frozen" bone...

BACKGROUND: Currently, there is no definition or classification system for quadrilateral plate (QLP) fractures; the aim was to anatomically and radiologically characterise the QLP, propose a definition and classify QLP fractures. METHODS: This study included an anatomical component and a radiological component. The anatomical study aimed at defining the characteristics of the QLP; the QLP was identified using four articulating bony pelvis specimens. A titanium mesh was placed on the specimens' quadrilateral surface; standard anteroposterior and oblique views were obtained, and axial CT images, to determine the radiological landmarks...

Evaluation of abnormalities in joint contact stress that develop after inaccurate reduction of an acetabular fracture may provide a potential means for predicting the risk of developing post-traumatic osteoarthritis. Discrete element analysis (DEA) is a computational technique for calculating intra-articular contact stress distributions in a fraction of the time required to obtain the same information using the more commonly employed finite element analysis technique. The goal of this work was to validate the accuracy of DEA-computed contact stress against physical measurements of contact stress made in cadaveric hips using Tekscan sensors...

PURPOSE: The results for fixation of comminuted posterior wall acetabular fractures are not very promising with reported complications in terms of osteoarthritis, nonunion and malunion which subsequently require conversion to total hip arthroplasty. The conversion to total hip arthroplasty is possible in patients over 50 years of age but not in younger patients. So this requires new methods for salvage of the native hip in young patients. METHODS: There were six patients in our series with highly comminuted posterior wall acetabular fractures where the fragments were excised and the gap filled with tricortical anterior iliac-crest strut autograft, fixed with screws and plate...
