INTRODUCTION: Cartilage wear is a concern after hemiarthroplasty. The precise pattern of the progression of wear has not been evaluated. We previously reported the application of radiostereonetric analysis (RSA) for the measurement of cartilage wear in patients. The purpose of this study was to report the amount and the orientation of the steady state wear of cartilage between 1 and 3 years after bipolar hemiarthroplasty. METHODS: 22 patients with a bipolar hemiarthroplasty for displaced femoral neck fracture were included...

BACKGROUND: Fractures of the acetabulum show a high, long-term complication rate. The aim of the present study was to determine the predictive value of clinical scoring and standardized, simplified gait analysis on the outcome after these fractures. METHODS: Forty-one patients with acetabular fractures treated between 2008 and 2013 and available, standardized video recorded aftercare were identified from a prospective database. A visual gait score was used to determine the patients walking abilities 6-m postoperatively...

The aim of this study was to investigate the sacroiliac joint injury mechanism. Two test configurations were selected from full scale car crashes conducted with the WorldSID 50(th) dummy resulting in high sacroiliac joint loads and low pubic symphysis force, i.e. severe conditions for the sacroiliac joint. The two test conditions were reproduced in laboratory using a 150-155 kg guided probe propelled respectively at 8 m/s and 7.5 m/s and with different shapes and orientations for the plate impacting the pelvis...

Surgical treatment of acetabular fractures is indicated in displaced cases in order to restore and stabilize the hip joint and the pelvic ring integrity. Posterior structure fractures must be treated through posterior pelvic surgical approaches. The Kocher-Langenbeck is the most recommended approach for the majority of posterior acetabular fractures.

BACKGROUND: Periprosthetic fractures of the acetabulum occurring during primary THA are rare. Periprosthetic occult fractures are defined as those not identified by the surgeon during the procedure which might be missed on a routine postoperative radiograph. However, it is unclear how frequently these fractures occur and whether their presence affects functional recovery. QUESTIONS/PURPOSES: In this study, using routine CT scans that were obtained as part of another primary hip arthroplasty study protocol, we retrospectively assessed (1) the prevalence of occult fractures of the acetabulum occurring during primary THA, (2) the location of occult fractures of the acetabulum during THA, and (3) risk factors contributing to such occult fractures...

PURPOSE: Due to the complexity of acetabulum, achieving anatomical contouring intra-operatively is difficult for surgeon. A 3D (dimensional) real model can facilitate us both in contouring the plate pre-operatively and in better pre-operative planning. Patient-specific pre-contoured plate in acetabular fracture has been studied by few researchers but randomized case-control study was lacking. Hence, we conducted a case-control study to evaluate the accuracy of patient-specific pre-contoured plate...

Metastatic lesions of the acetabulum can be painful and debilitating. First-line treatment is multimodal and consists of disease-specific chemotherapy, osteoclastic inhibitors, analgesics, and radiation therapy. When these therapies fail, surgical intervention usually is indicated and varies from regional defect stabilization to large periacetabular reconstructions that are demanding procedures with high rates of complications. Percutaneous cement augmentation (acetabuloplasty) of lesions in selected patients has been explored as a less invasive method of lesional control...

Traumatic hip fracture-dislocations are associated with chondral and labral pathology as well as loose bodies that can be incarcerated in the hip joint. Incarceration, such as interposed labrum between acetabulum and femoral head that is not readily visualized preoperatively, is a rare but important cause of pain and can potentially be a source for early degeneration and progression to osteoarthritis. We present three cases, arthroscopic surgery of incarcerated acetabular osseo-labral fragment following reduction of traumatic hip fracture-dislocation...

The typical injury pattern of a posterior hip dislocation includes posterior wall fracture, capsular injury, and muscular strain. This report presents an example of a posterior wall acetabulum fracture-dislocation associated with complete hip abductor tendon and capsular avulsion from the femur. The patient was found to have an unstable hip despite a small posterior wall fragment due to the extensive soft tissue injury. This was repaired. The patient had improvement in function initially, but ultimately required repair of the hip abductor tendons...

Osteoarthritis of the hip remains a prevalent disease condition that influences ever-changing treatment options. Procedures performed to correct anatomic variations, and, in turn, prevent or slow the progression of osteoarthritis, are aptly referred to as types of hip preservation surgery (HPS). Conditions that predispose individuals to femoroacetabular impingement (FAI), including pincer- and cam-type morphology, and hip dysplasia are specifically targeted in HPS. Common surgical interventions include acetabuloplasty, osteochondroplasty, periacetabular osteotomy (PAO), and derotational femoral osteotomy (DFO)...

In contrast to periprosthetic fractures of the femur, periprosthetic fractures of the acetabulum are rare complications - both primary fractures and fractures in revision surgery. This topic is largely under-reported in the literature; there are a few case reports and no long term results. Due to an increase in life expectancy, the level of patients' activity and the number of primary joint replacements, one has to expect a rise in periprosthetic complications in general and periprosthetic acetabular fractures in particular...

We report a case of a unilateral testicular dislocation to the superficial inguinal region associated with a lateral compression type pelvic ring injury (OTA classification 61-C3.3a2, b2, c3) and left T-shaped acetabulum fracture (OTA classification 62-B2) in a 44-year-old male who was in a motorcycle accident. The testicular dislocation was noted during the emergency department primary survey, and its location and viability were verified with ultrasound. The testicle was isolated during surgical stabilization of the left acetabulum through a Pfannenstiel incision and modified-Stoppa approach and returned through the inguinal canal to the scrotum...

BACKGROUND: Previous work established resuscitation parameters that minimize complications with early fracture management. This Early Appropriate Care (EAC) protocol was applied to patients with advanced age to determine if they require unique parameters to mitigate complications. METHODS: Between October 2010 and March 2013, 376 consecutive skeletally mature patients with unstable fractures of the pelvis, acetabulum, thoracolumbar spine, and/or proximal or diaphyseal femur fractures were treated at a level I trauma center and were prospectively studied...

PURPOSE: There has recently been an increase in the number of fellowship trained orthopaedic trauma surgeons, raising concerns that the surgical experience of early career surgeons may be diluted. We sought to evaluate the change in complex trauma case volume of orthopaedic trauma surgeons sitting for Part II of the American Board of Orthopaedic Surgeons certification examination. METHODS: The case log data from all surgeons taking Part II of the American Board of Orthopaedic Surgeons examination over a 13-year period (2003-2015) was evaluated...

OBJECTIVE: During total hip arthroplasty (THA), the location of the acetabular prosthesis is very important for guaranteeing successful surgery. However, this remains a challenge for many surgeons. This study aimed to investigate the feasibility of using the intraoperative fluoroscopic iliopubic tangential angle (IPTA) to determine the valgus angles of acetabular prostheses. METHODS: In the first stage, the IPTA and valgus angles of native acetabula were defined and measured in 102 THAs obtained from the picture archiving and communication systems of our hospital...

Introduction: Pelvic ring injuries occur in 3-8 % of patients with fractures. They are rare, with an annual incidence of only 19-37 per 100,000 people annually. There have been publications on the generation of these injuries, as well as their diagnosis and treatment concepts, but there is little information on how these injuries impact the ability to work. Patients: The study covered all hospitalised patients between January 2003 and December 2011 with a pelvic ring injury, who had already been included in the data collection of the AG Becken III and who had had a work-related accident...

Acetabular nonunions are rare, especially after operative treatment of an acetabular fracture. There are only single reports of the reconstruction and therapy of acetabular nonunion. Furthermore, there are fewer reports for treatment of acetabular nonunion with a long follow-up. We report a successful revision of an acetabular nonunion after transversal fracture and previous operative intervention, as well as the long-term follow-up after revision surgery.
