Testing of a Portuguese Method for Estimating Skeletal Age at Death in Adults Using the Acetabulum on an American Sample
… to test the accuracy of age estimation using the acetabulum. Methods for determining information from the os coxae are essential tools in archaeology and forensic anthropology. Variables from the ilium, ischium, and pubis have been used to determine sex and estimate age. Establishing a third area …

A Novel Method For Determining Acetabular Orientation
Enhanced knowledge of the acetabulum is of paramount importance in the diagnostic, planning, and execution stages of procedures and treatments targeting the hip joint. The convoluted and highly variable morphology of the structures comprising the bony pelvis make ascertaining measures of the …

Finite Element Model of the Pediatric Hip Joint During the Barlow Maneuver
… dislocation of an unstable femoral head in the acetabulum of the pelvis. This is a result of an abnormal or underdeveloped growth of the acetabulum and triradiate cartilages and/or an out of place and uncentered femoral head in the acetabulum. This underdevelopment, if not diagnosed and treated …

Mechanism of Hip Dysplasia and Identification of the Least Energy Path for its Treatment by using the Principle of Stationary Potential Energy
… is not located in its natural position in the acetabulum (hip socket). Several treatment methods are being implemented worldwide to treat this abnormal condition. One of the most effective methods of treatment is the use of Pavlik Harness, which directs the femoral head toward the natural …

A Tale of Two Studies: A Biomechanical Comparison of Extrapelvic and Intrapelvic Fixation for Acetabular Fractures among the Elderly and a Comparison of Dosage Accuracy and Precision for Traditional and Incremental Syringes
… significantly towards the strength of the acetabulum until higher loads are reached. However, reoccurring trauma is not unusual, particularly among fall victims. An intrapelvic plate could prevent reprotrusion of the acetabulum in such scenarios.

Abduction Contractures within Infants with Developmental Dysplasia of the Hip
… or dislocation of the femoral head from the acetabulum. Through a rating system by the International Hip Dysplasia Institute or Graf System, hips are rated based on their level of instability or dislocation and the infant is then prescribed a treatment. While Finite element models of …

Automated determination of the theoretical range of hip motion prior to total hip arthroplasty using 3D models created from pelvic CT scans
… artificial femoral head pops out of the replaced acetabulum due to a leverage effect. It affects about 4,000 patients a year in the UK, for 80,000 THA1. To prevent this complication, surgeons would benefit from estimating the range of angular hip motion that can be achieved by their patient …

Morphologische und biomechanische Eigenschaften des Hüftgelenks (Articulatio coxae) des Hundes (Canis familiaris)
… the joint surfaces as well as in the roof of the acetabulum and the perifoveal area of the caput ossis femoris. The anteversion of the Os femoris was determined by a computed tomographical method. The findings allowed the assumption of a causal relationship between a reduced anteversion angle and …

Computational Investigation of the Biomechanics of Babywearing in Regards to Developmental Dysplasia of the Hip
… femoral head is not properly situated inside the acetabulum. Etiology of the condition is in part congenital and developmental, with a difference of DDH prevalence between ethnicities. Incidence of DDH is also in some part dependent on cultural practices and activities of the mother and child. The …

Acetabularia-Rhodopsin, eine lichtgetriebene Protonenpumpe aus einem autotrophen Eukaryoten
Ein Rhodopsin aus Acetabularia acetabulum (AR) wird mit molekulargenetischen und elektrophysiologischen Mitteln charakterisiert. Mithilfe der reversen Transkription und der Polymerasekettenreaktion wurde auf der Grundlage einer veröffentlichten, unvollständigen Sequenz, das gesamte Transkript eines …

Decreasing Error in Functional Hip Joint Center Calculation using Ultrasound Imaging
… is determined by moving femur with respect to acetabulum. A popular way for measuring this movement is through an optical motion capture system. This method is fast and economical for most applications where we require an instant HJC even though the reconstruction error in bone position …

Evalution of a Model for Experimentally-Induced Osteoarthritis in the Hip Joint of the Dog
… of an ilial bone plate, causing rotation of the acetabulum to reduce dorsal coverage of the femoral head. Sham group dogs received identical osteotomies but were plated in normal orientation. All dogs had force plate and subjective lameness evaluations pre-operatively and post-operatively. Pelvic …

Development of clinical assessment strategies for patients undergoing total hip arthroplasty (THA)
… head fits into a cup that is inserted into the acetabulum. There are basically two implant technologies being used in the operation, either bone cement is used to fix the prosthesis into the femur or a press-fitting technique is used to insert the prosthesis into the femur. Both techniques have …

Localization of Human Pelvis Anatomical Coordinate System Using Ultrasound Registration to Statistical Shape Model
… placement of the femur prosthesis in the acetabulum in THR. The general approach to localize the orientation of the pelvic anatomical coordinate system (PaCS) is to use intra-operative X-ray fluoroscopy in a specialized interventional radiology facility to guide the procedure. Employing …

A study on stability of an all polyethylene pressfit acetabular cup
… the density of 0.5 g/cm³ was used to mimic human acetabulum bone. Two different cups sizes (28 and 32mm articulation) were placed into the bone substrate with 7kN and three different failures were induced 7 times in series by pulling out, twisting out and levering out the cup out of its cavity …

Finite Element Analysis and Validation of Hip Joints with the Main Types of Femoroacetabular Impingement
… minimum principal stresses experienced in the acetabulum. Overall, the two types of femoroacetabular impingement change the stress experienced by both the femur and the pelvis. The results of this study demonstrate that acetabular stresses can increase as a result of femoroacetabular …
