A variety of techniques have been used to determine intra-operative leg length during total hip arthroplasty. One method often described is using the tip of greater trochanter as the reference for the rotation centre of the femoral head to align the femoral component. There is little in the literature to support this method of leg length restoration. We analysed standard anterior-posterior pelv...

OBJECTIVE To generate and report standardized growth curves for weight, length, head circumference, weight/length, and BMI for non-growth hormone-treated white infants (boys and girls) with Prader-Willi syndrome (PWS) between 0 and 36 months of age. The goal was to monitor growth and compare data with other infants with PWS. METHODS Anthropometric measures (N = 758) were obtained according to...

BACKGROUND A study on the cephalic index was carried out on subjects from school students in Ogbia tribe of Bayelsa state in the Niger Delta region of Nigeria. This study determined the cephalic indices among the school students. In the present study, seven hundred subjects were randomly selected from secondary schools comprising 350 males and 350 females, respectively, with age range from 11-2...

An analysis of channel head locations provides insight into controls on drainage density, the response of landscapes to climatic change, and the delineation of source areas for channel network simulations. Channel heads and colluvial deposits were mapped in a roughly 2 km 2 area near San Francisco, California, and, although channel heads are located within colluvial deposits in hollows, many su...

The purpose of this study was to investigate the effects of head hair on thermoregulatory responses when cooling the head under heat stress. Eight young males participated in six experimental conditions: normal hair (100-130 mm length) and cropped hair (5 mm length) with three water inlet temperatures of 10, 15, and 20°C. The head and neck of subjects were cooled by a liquid perfused hood while...

This study explored the radiographic and anatomical differences in normal shoulders between men and women, as well as factors such as race, height, weight, and age. A total of 205 patients with documented normal anatomical radiographs comprised the study population. Five fellowship-trained orthopedic surgeon reviewers measured head diameter, humeral head size, head to tuberosity distance, great...
