The forelimbs of higher vertebrates are composed of two portions: the appendicular region (stylopod, zeugopod and autopod) and the less prominent proximal girdle elements (scapula and clavicle) that brace the limb to the main trunk axis. We show that the formation of the muscles of the proximal limb occurs through two distinct mechanisms. The more superficial girdle muscles (pectoral and latiss...
The Argentine anchovy, Engraulis anchoita, plays a vital role as key prey species for several marine predators in the north Patagonian ecosystem of Atlantic Ocean. Reconstructing length and weight each consumed specimen is essential to provide detailed description trophic ecology top predators. Predictive linear regression equations were calculated stock anchovy estimate parameters length-weigh...
The acromioclavicular joint is commonly affected by trauma to the shoulder girdle due to its subcutaneous position. Athletes who participate in contact sports, such as hockey, football, rugby, and soccer, are particularly susceptible to such injuries. These injuries, however, also occur during noncontact sports such as baseball, skiing, and cycling. The majority of acromioclavicular injuries oc...
The incidence of loosening of a cemented glenoid component in total shoulder arthroplasty, detected by means of radiolucent lines or positional shift of the component on true anteroposterior radiographs, has been reported to be between 0% and 44%. Radiolucent lines are, however, difficult to detect and to interpret because of the mobility of the shoulder girdle and the obliquity of the glenoid ...
A fossil discovery in the mid-Cretaceous Blackleaf Formation of southwest Montana, USA, has yielded the first trace and body fossil evidence of burrowing behaviour in a dinosaur. Skeletal remains of an adult and two juveniles of Oryctodromeus cubicularis gen. et sp. nov. a new species of hypsilophodont-grade dinosaur, were found in the expanded distal chamber of a sediment-filled burrow. Corres...
Chronic osteomyelitis is a childhood disease and so it is not uncommon to diagnose it in a 10 year old boy who is suffering from pains and discharging sinuses from the left shoulder girdle. What is not common is the involvement of the clavicle in this infective process and even more uncommon is for the whole length of the clavicle to sequester. This case report describes a rare case of chronic ...
The angular displacements of the longitudinal axis of the trunk, and of the latero-lateral axes of pelvis and shoulder girdle were measured in five normal subjects and four AK amputees during level walking at different speeds. Amputees used single axis prostheses with the SACH foot. Spatial measurements were carried out in three dimensions by means of a photogrammetric technique. The time funct...
Elasto fibroma dorsi is a rare tumour of the shoulder girdle that usually arises at the infra scapular area. We present a 57-year-old male with a soft tissue swelling on his right infra scapular area of 6 months duration. It was a painless lesion which caused him discomfort while sleeping. Preoperative imaging revealed bilateral tumours but the left tumour was impalpable. The surgery itself was...
