Developmental dysplasia of the hip (DDH) is a common musculoskeletal disorder characterized by a mismatch between acetabulum and femoral head. Mechanical force plays an important role during the occurrence and development of abnormities in acetabulum and femoral head. In this study, we established a mechanical force model named cyclic compressive stress (Ccs). To analyze the effect of Ccs on DDH, we detected special genes in chondrocytes and osteoblasts. Results showed that Ccs downregulated chondrogenesis of ADTC5 in a concentration-dependent manner...

Determining three-dimensional (3D) acetabular orientation is important for several orthopaedic scenarios, but the complex geometries of both pelvis and acetabulum make measurements of orientation unreliable. Acetabular orientation may also differ between the sexes or racial groups. We aimed to (1) establish and evaluate a novel method for measuring 3D acetabular orientation, (2) apply this new method to a large population of Chinese subjects, and (3) report relevant characteristics of native acetabular orientation in this population...

Foreign bodies in the bladder are among the strangest differential diagnoses in the lower urinary tract symptoms (LUTS) and may be missed in initial medical evaluations. We present a 63-year-old man who was visited in the emergency department because of obstructive and irritative lower urinary tract symptoms. Two months earlier, he had a pelvic fracture due to motor vehicle accident and underwent an open reduction and internal fixation of the pubic rami and right acetabulum by an anterior ilioinguinal approach...

INTRODUCTION: Posterior hip dislocation of the hip with acetabular fracture is a challenging problem to treat. Such dislocations are associated with avascular necrosis of the femoral head if neglected. Managing such conditions with total hip replacement (THR) is very difficult because of associated altered anatomy. CASE PRESENTATION: We hereby report a two-year neglected hip dislocation with associated acetabular fracture successfully treated with uncemented THR...

INTRODUCTION: There have been several reports on arthroscopically assisted removal of the bullet imbedded in hip joint in the literature. Similarly, in this case, a bullet lodged in acetabulum was extracted with arthroscopic technique. What makes this case unique in the literature is that the bullet removed from the acetabulum traversed the femoral neck. CASE REPORT: Male patient aged 32 years with a low-velocity gunshot wound was referred to the emergency room on August 28, 2012...

Acetabular fractures can be challenging to treat, in part because the shape of the fixation plates needs to be adjusted during the surgical procedure. One possibility is to generate a model of the uninjured half of a fractured pelvis with 3D printing, and then pre-contour the fixation plates preoperatively on this model. The purpose of this technical note is to describe how we used 3D printing as an aid to treat acetabular fractures. The quality of the fracture reduction, fracture fixation and time savings were evaluated...

We report the case of a 63-year-old female patient referred to our department due to an early postoperative complication resulting from intraoperative fault. During the preparation of a bone socket for the acetabular cup, the acetabular fossa was broken, forming an extensive segmental defect of the diameter of the reamer used. An attempt to stabilize the acetabular prosthesis using bone cement without repairing the bone defect was ineffective and inappropriate. During the deposition of the acetabular prosthesis on the cement, much of the cement was pushed beyond the outline of the bony acetabulum...

Fasciolosis an economically important global disease of ruminants in the temperate and tropical regions, caused by Fasciola hepatica and F. gigantica, respectively, also poses a potential zoonotic threat. In India alone it causes huge losses to stakeholders. Anthelmintics including triclabendazole have been used to control this menace but the emerging resistance against the available compounds necessitates identification of novel and alternative therapeutic measures involving plant derived natural compounds for their anthelmintic potential...

INTRODUCTION: In bipolar hemiarthroplasty, migration of the outer cup component into the acetabular cup, with evidence of severe osteolysis in the acetabulum, commonly occurs without loosening of the femoral component. The merits of retaining the stable femoral component in these cases have been debated. Our study aimed to determine whether revision of the acetabular component in isolation could be successfully performed. MATERIALS AND METHODS: The data of 54 patients (61 hips), 44 women, and 10 men, aged 67...

AIMS: The pelvis rotates in the sagittal plane during daily activities. These rotations have a direct effect on the functional orientation of the acetabulum. The aim of this study was to quantify changes in pelvic tilt between different functional positions. PATIENTS AND METHODS: Pre-operatively, pelvic tilt was measured in 1517 patients undergoing total hip arthroplasty (THA) in three functional positions - supine, standing and flexed seated (the moment when patients initiate rising from a seated position)...

BACKGROUND: Current dogma contends that prolonged treatment of a dislocated hip in Pavlik harness beyond 3 weeks will cause "Pavlik harness disease." To our knowledge, however, no previous studies have documented objective morphologic changes to the acetabulum from continued treatment of a persistently dislocated hip. METHODS: We retrospectively reviewed a consecutive series of infants with developmental dysplasia of the hip, below 6 months old, who failed Pavlik treatment from a single, tertiary-care pediatric hospital and a multicenter, international study group...

BACKGROUND: Acetabular dysplasia (AD) is a well-known cause of osteoarthritis (OA) of the hip, with its prevalence previously determined on plain radiography. The prevalence of preexisting AD was reported as 7.3% in a patient-based Asian population. Although computed tomography (CT) could evaluate AD in multiple planes, its prevalence using multiplanar CT images has not been reported. We investigated its prevalence with CT on coronal, axial, and sagittal planes and then determined if adding the axial and sagittal planes enhanced the investigation...

PURPOSE: This study aims at sharing our experience as how to obtain and identify axial view image of the acetabular anterior column in patients. METHODS: Pelvic computed tomography data of six normal adults were used to reconstruct three-dimensional (3D) models. The transparency of each 3D model was downgraded at the view perpendicular to the cross section of the anterior column axis to simulate the anterior column axial view image. Fluoroscopy was performed in all patients to obtain the anterior column axial view image in the operating room...
