INTRODUCTION Fetal head descent is used to demonstrate the maternal pelvis capacity to accommodate the fetal head. This is especially important in low resource settings that have high rates of childbirth related maternal deaths and morbidity. This study looked at maternal height and an additional measure, maternal pelvis height, from automotive engineering. The objective of the study was to det...

enormous advantage of antenatal examination in the large majority of cases which come into the Hospital for delivery. Dr Ballantyne and Dr Francis J. Browne endeavour to ascertain four things : (i) The size of the pelvis; (2) the size of the child ; (3) the relative size of the child and the pelvis ; (4) the position of the child. The size of the pelvis is an important thing in a way, because i...

The purpose of this study was to clarify the dynamics of the pelvis axis rotation during the golf swing. Sixteen skilled golfers performed swings with the driver. The 3D kinematic data and ground reaction forces were collected using an optical motion analysis system and two force platforms. The dynamic components of the pelvis angular acceleration were calculated as a function of 1) joint torqu...

Urothelial carcinoma (UC) originated from renal pelvis is the common tumor of the urinary system, however, neoplasia of the renal pelvis in duplex kidneys is extremely rare, especially in the complete renal and ureteral duplex cases. We present the first case of renal pelvis UC of the upper moiety in a complete right renal duplex. This male patient has bilateral complete renal and ureteral dupl...

High energy fractures of the pelvis are a challenging problem both in the immediate post-injury phase and later when definitive fixation is undertaken. No single management algorithm can be applied because of associated injuries and the wide variety of trauma systems that have evolved around the world. Initial management is aimed at saving life and this is most likely to be achieved with an app...

This book represents the first single volume in the English language dealing with procedures aimed at the accurate measuring of the female pelvis and the fetal head in utero. Because of the unreliability of the usual external pelvic measurements the obstetrical studies of recent years have tended to neglect this fundamental part of obstetrics. Indeed, until the advent of the Roentgen mensuratio...

In this study, three-dimensional finite element models were created from computer tomography data to study lateral impact fractures of the pelvis. The models reflect the complex geometry and material properties of the pelvis. The models were compared to published experimental results for validation. Dynamic analyses of the pelvic structure were performed for different peak forces in the range o...

The goal of this paper is to access to pelvis position and morphology in standing posture and to determine the relative locations of their articular surfaces. This is obtained from coupling biplanar radiography and bone modeling. The technique involves different successive steps. Punctual landmarks are first reconstructed, in space, from their projected images, identified on two orthogonal stan...

The control of upper body (UB) orientation relative to the pelvis in the frontal plane was characterized by analyzing responses to external perturbations consisting of continuous pelvis tilts (eyes open [EO] and eyes closed [EC]) and visual surround tilts (EO) at various amplitudes. Lateral sway of the lower body was prevented on all tests. UB sway was analyzed by calculating impulse-response f...

during fixation of a femoral neck fracture in a 23-year-old male patient with cannulated screws, a broken guide wire fragment inadvertently advanced through the hip joint and protruded into the pelvis. a second surgical approach was needed to remove the broken fragment from the pelvis. awareness of such a potentially devastating complication will make surgeons more cautious during implementatio...
