The results of the formulae can contain small but significant errors in the cases of young people, and errors of up to 41.5% for older people. [8] Moreover, the size of the humerus is not in fact equal in all individuals. [5] It also varies with nutritional status. [1]
The humerus (/ ˈ h juː m ər ə s /; pl.: humeri) is a long bone in the arm that runs from the shoulder to the elbow.It connects the scapula and the two bones of the lower arm, the radius and ulna, and consists of three sections.
It is formed by the articulation between the head of the humerus and the lateral scapula (specifically-the glenoid cavity of the scapula). The "ball" of the joint is the rounded, medial anterior surface of the humerus and the "socket" is formed by the glenoid cavity, the dish-shaped portion of the lateral scapula.
A Doppler ultrasound blood flow detector, commonly called Doppler wand or Doppler probe, and a sphygmomanometer (blood pressure cuff) are usually needed. The blood pressure cuff is inflated proximal to the artery in question. Measured by the Doppler wand, the inflation continues until the pulse in the artery ceases.
If a joint effusion is depicted in the ultrasound, two-plane X-ray imagery is necessary to diagnose the fracture. The standard procedure is the elbow-SAFE algorithm. [ 18 ] The sensitivity of the method in comparison with X-ray imaging is 97.9 percent, the specificity is 95 percent, the positive predictive value is 0.95, and the negative ...
The first action is flexion of the humerus, as in throwing a ball underhand, and in lifting a child. Secondly, it adducts the humerus, as when flapping the arms. Thirdly, it rotates the humerus medially, as occurs when arm-wrestling. Fourthly the pectoralis major is also responsible for keeping the arm attached to the trunk of the body. [7] [8]
For example, human body height is to be the length of eight heads, with an additional one-quarter head for neck length. Leg length is to be four head lengths. [1] Forensic estimation of stature is part of the identification process necessary when dismembered body parts are found. It is also possible to estimate the stature from bones. [2]
Struthers' ligament is a feature of human anatomy consisting of a band of connective tissue at the medial aspect of the distal humerus. It courses from the supracondylar process of the humerus (also known as avian spur) to the medial epicondyle of the humerus. [2] It is not a constant ligament, and can be acquired or congenital.
