The year nineteen hundred and thirty-nine marks the centennial of the publication of one of the significant contributions to obstetric literature, for it was just a century ago that Franz Carl Naegele published his treatise, Das schr2ag verengte Becken.3 For this reason it is gratifying to learn that during the present year a centennial edition, in English, is to be published by Dr. A. F. Hellm...

AIMS To describe the outcomes of a large number of patients with pelvic osteosarcoma, and to define the guidelines for appropriate treatment. METHODS We reviewed 60 consecutive patients with primary pelvic high-grade osteosarcoma. The tumour involved the whole hemipelvis in 15 cases, while the most common location was the iliac wing in 29 cases (48.3%): 25 of these adjacent to or passing the ...

Leiomyoma is a benign tumour of smooth muscle origin, which can also affect many organs specially kidneys. In kidneys, it is mostly found in the renal capsule but rarely does it also involve the renal pelvis. It is mostly found in middle-aged women. A 25-year-old man presented with hematuria histologically secondary to proven leiomyoma of left renal pelvis with unusual clinical features underwe...

Sarcoma of the kidney is a rare condition. Leiomyosarcoma is the most common of the kidney sarcomas. Renal leiomyosarcoma usually originates from the smooth muscle layers of the kidney, for example, the renal capsule and renal vessels. Renal pelvis neoplasms, however, are primarily transitional cell carcinomas, and renal pelvis leiomyosarcomas are extremely uncommon. Renal pelvis leiomyosarcoma...

The position and orientation of a vehicle occupant’s pelvis are important for seat design and the provision of safety belts. However, the direct measurement of pelvis location in a vehicle seat is difficult due to interference from the vehicle and its seat structure, as well as driver factors such as abdomen adiposity. An optimization method was developed to locate the driver’s pelvis based on ...

Pre-clinical evaluations of acetabular prosthesis designs call for an accurate numerical model of the natural pelvis. Stress analysis of the pelvis during physiological loading conditions is necessary to understand the load transfer mechanism, its relation with bone morphology and to analyze the deviations in stress distributions due to implantation of the acetabulum. Despite a few experimental...

While not proven definitively, the hypothesis that intra-articular psoas tendon release allows fluid to track into the retroperitoneal space has been widely accepted. This study attempts to identify the path through which fluid enters the pelvis and retroperitoneal space. Six hemi-pelvis human cadaveric specimens were utilized for this study. 3 specimens underwent a capsulotomy and psoas tendon...

INTRODUCTION In sub Saharan Africa, childbirth remains a challenge that creates the need for additional screening tools. Maternal pelvis height, which is currently in use by automotive engineers has previously been shown to have significant associations with various childbirth related outcomes and events. This study set out to determine the associations between maternal: Age, height, weight and...

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 and eyes closed) and visual surround tilts (eyes open) at various amplitudes. Lateral sway of the lower body was prevented on all tests. UB sway was analyzed by calculating impulse-response func...
