BACKGROUND While anterior glenohumeral instability has been shown to be common in young athletes, the risk factors for injury are poorly understood. PURPOSE/HYPOTHESIS To determine the modifiable and nonmodifiable risk factors for anterior shoulder instability in a high-risk cohort. The hypothesis was that specific baseline factors would be associated with the subsequent risk of injury. STU...

Thirty participants tuned a drum machine to their preferred dance tempo. Measurements of height, shoulder width, leg length, and weight were taken for each participant, and their sex recorded. Using a multiple regression analysis, leg length was found to be the single best predictor of preferred dance tempo. The results are consistent with a biomechanical “resonance” model of dancing.

The variant morphometry of bicipital groove is reported to be associated with pathologies of biceps tendon and is useful in surgical procedures in this region. The pathologies of biceps tendon are frequent causes of shoulder pain. Therefore, under the condition of paucity of data pertaining to north Indians, not only morphometric analysis of bicipital groove and a new definition of narrow/shall...

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...

An anatomic study was conducted on 49 dried cadaveric humeri and 24 dried cadaveric scapula to ascertain the variability of the following parameters: humeral neck angle, humeral head retroversion, humeral head medial offset, humeral head posterior offset, humeral head diameter glenoid height, glenoid width, and the glenoid height to width ratio. For verification purposes, the results of this st...

skin and leather characteristics of hair-type goats were studied in relation to their sex and age, using 100 randomly-selected skin from goats reared in east west iran. mean weights of skin and leather were 859.2±35.2 and 357.4±16.2 g, and the length and width of leather ranged from 60 to 121 and 41 to 87 cm, respectively. age had a significant effect on the weight and area of skin and leather....

The detection and mapping of segregating quantitative trait loci (QTL) that influence withers height, hip height, hip width, body length, chest width, chest depth, shoulder width, lumbar width, thurl width, pin bone width, rump length, cannon circumference, chest girth, abdominal width and abdominal girth at weaning was conducted on chromosomal regions of bovine chromosome one. The QTL analysis...
