BACKGROUND: The direct anterior approach on a regular operating room table has been reported with low dislocation rates. This might be beneficial for complex primary total hip arthroplasty (THA) such as in patients with cerebral palsy or following femoral or pelvic osteotomies. Extending the approach is often required to overcome problems such as acetabular deformities or severe contractures. METHODS: We retrospectively evaluated the results and complications of 29 patients with 37 complex primary THA in which an extensile approach was used...

Periprosthetic acetabular fractures in geriatric patients are rare injuries; however, the incidence is increasing because of the current demographic developments. For diagnosis of periprosthetic acetabular fractures, conventional X‑ray images are regularly complemented by computed tomography (CT). For exclusion of loosening of the prosthesis more advanced techniques, such as single photon emission CT (SPECT/CT) are applied. In addition to classification of periprosthetic acetabular fractures by the traditional system of Letournel there are several other classification systems, which take into account the etiology of the fracture and the stability of the prosthesis...

INTRODUCTION: It is critical to achieve both proper component positioning and intact muscle balance if satisfactory results are to be attained after total hip replacement (THR). There have been fewer studies on minimally invasive (MI) THR than standard approaches. The objective of this paper is to present the early clinical and radiological results of posterolateral MI THR. MATERIALS AND METHODS: The retrospective analysis of the records of patients undergoing posterolateral MI THR surgery between 2011 and 2014 was the basis of this study...

REVIEW
José Batista Volpon
The femoroacetabular impingement (FAI) is as condition recently characterized that results from the abnormal anatomic and functional relation between the proximal femur and the acetabular border, associated with repetitive movements, which lead labrum and acetabular cartilage injuries. Such alterations result from anatomical variations such as acetabular retroversion or decrease of the femoroacetabular offset. In addition, FAI may result from acquired conditions as malunited femoral neck fractures, or retroverted acetabulum after pelvic osteotomies...

The ilioinguinal approach is one of the standard approaches in the treatment of displaced acetabular fractures used during the last decades (9). The meta-analysis of Giannoudis et al. showed that 21.9% of acetabular fractures were historically treated using this approach (3). One of the disadvantages of this study was, that studies focussing especially on posterior wall stabilization and studies dealing with more complex fracture types treated by extended approaches were integrated. Thus, these fracture types were overrepresented...

BACKGROUND: Acetabular fractures remain challenging to diagnose, particularly when they are complex. An accurate diagnosis is nevertheless crucial to selectthe best surgical strategy.None of the training methods described to date relies on the Letournel classification with a detailed analysis of each abnormality seen by computed tomography (CT). We therefore prospectively assessed a CT-based diagnostic method by 1) determining the rate of correct diagnoses by orthopaedic surgeons before and after training in the method, 2) comparingthe times needed to read the CT images before and after training, 3) and assessing therepeatability of the method...

Posterior wall acetabular fractures involving a large portion the wall's width and with extensive comminution are difficult fractures to manage operatively. Cortical substitution with a pelvic reconstruction plate and supplemental spring plates has been the traditional means of fixation for these fractures. This option, however, requires the use of multiple, unlinked plates and provides no reliable option for peripheral fixation in comminuted fragments. We describe a novel technique for operative fixation of large, comminuted posterior wall fractures using a single distal tibia pilon plate with the option for peripheral locking screw fixation and report on a series of 20 consecutive patients treated with this method...

The cement-in-cement technique is useful in the setting of revision total hip arthroplasty (THA), especially to gain acetabular exposure, change a damaged or loose femoral component, or change the version, offset, or length of a fixed femoral component. The goal of this retrospective study was to assess the clinical and radiographic characteristics of revision THA using the cement-in- cement technique. Between 1971 and 2013, a total of 63 revision THAs used an Omnifit (Osteonics, Mahwah, New Jersey) or Exeter (Howmedica, Mahwah, New Jersey) stem and the cement-in-cement technique at the senior author's institution...

The aim of the present study was to describe the application of 3D printed templates for intraoperative navigation and simulation of periacetabular osteotomies (PAOs) in a cadaveric model.Five cadaveric specimens (10 sides) underwent thin-slice computed tomographic scans of the ala of ilium downwards to the proximal end of femoral shaft. Bernese PAO was performed. Using Mimics v10.1 software (Materialise, Leuven, Belgium), 3D computed tomographic reconstructions were created and the 4 standard PAO bone cuts-ischial, pubic, anterior, and posterior aspects of the ilium-as well as rotation of the dislocated acetabular bone blocks were simulated for each specimen...

Acetabular fractures have always been very challenging for orthopedic surgeons; therefore, appropriate preoperative evaluation and planning are particularly important. This study aimed to explore the application methods and clinical value of preoperative computer simulation (PCS) in treating pelvic and acetabular fractures. Spiral computed tomography (CT) was performed on 13 patients with pelvic and acetabular fractures, and Digital Imaging and Communications in Medicine (DICOM) data were then input into Mimics software to reconstruct three-dimensional (3D) models of actual pelvic and acetabular fractures for preoperative simulative reduction and fixation, and to simulate each surgical procedure...

BACKGROUND: The use of reconstruction plates and lag screws has been recommended for fractures to the posterior wall of the acetabulum. However, little information about the rigidity of recommended forms of fracture fixation is available. This study aimed to evaluate the biomechanical difference among the fixation systems. METHODS: A posterior wall fracture, which is represented by softer elements with lower elastic modulus, was created along an arc of 40-90° about the acetabular rim...

BACKGROUND: Dislocation of primary THA (total hip arthroplasty) is one of the most undesirable complications with an incidence ranging from 2% to 5%. Several risk factors are described, related to the patient, surgery, or prosthetic design. The aim of the study was to assess risk factors and their potential influence on dislocation. MATERIALS AND METHODS: 387 primary THA were performed between September 2005 to December 2008 at our institute (Varese, Italy) through a modified posterior-lateral approach...

Andrew G Dubina, Niluka Wickramaratne, Robert V O'Toole, Theodore T Manson
BACKGROUND: Trochanteric osteotomies are performed in conjunction with standard approaches to improve surgical exposure during open reduction and internal fixation (ORIF) of acetabular fractures. The literature on total hip arthroplasty reports nonunion rates as high as 30% associated with trochanteric osteotomies; however, few data exist regarding the outcomes of trochanteric osteotomies for acetabular fracture surgery. Our hypotheses were 1) patients receiving trochanteric osteotomies during ORIF of acetabular fractures have a low rate of nonunion of the osteotomy fragment, and 2) hip abduction precautions are not necessary with digastric type osteotomies...

Patient demographics, physiologic variables, and injury characteristics predictive of mortality and major systemic complications following operative fixation of acetabulum fractures were identified using the National Sample Program of the National Trauma Data Bank. Age older than 60 years, obesity, and Injury Severity Score greater than 15 portended a statistically significant increase in mortality and major systemic complications (P≤.05). Systolic blood pressure less than 90 mm Hg and Glasgow Coma Scale score less than 8 were also significant predictors of mortality and major systemic complications (P<...

BACKGROUND: When surgeons reconstruct hips with a high dislocation related to severe developmental dysplasia of the hip (DDH) in total hip arthroplasty (THA), archiving long-term stable implant fixation and improving patient function and satisfaction remain challenging. The purpose of this study was to evaluate the 10-year outcomes of transverse subtrochanteric shortening osteotomy in cementless, modular THA in Crowe type IV-Hartofilakidis type III DDH. METHODS: We reviewed 62 patients (76 hips) who underwent cementless THA with transverse subtrochanteric shortening osteotomy from 2002-2010...
