bone metastases) are common and result in significant morbidity in patients with metastatic disease.Although the diagnosis is often straightforward, especially as in many cases there is a well-documented history of metastatic malignancy, sometimes they may mimic benign disease or other primary malignancies. x The modern era of surgical stabilization of rib fractures (SSRF) was ushered in by the publication of the inaugural randomized controlled trial (RCT) in 2002 [1]. During this time, the mammary glands grow in size and volume and begin resting on the chest. Even though their monophyly has been well-supported, their intrarelationships have been obscure, and their phylogenetic placement even more. Skeletal metastases (a.k.a. Elements homologous with the stylopod (femur and humerus) and zeugopod (radius, ulna, tibia, and fibula) have long been known to occur in tetrapodomorphs (e.g. Since that time, interest in SSRF has grown dramatically, as evidenced by an over eight-fold increase in use of the operation for patients with a diagnosis of flail chest from 2007 to 2014 [2-4]. Much progress has been made on this front recently. It extends the forearm and abducts the elbow as the forearm pronates. The scapula, also known as the shoulder blade, is a flat triangular bone located at the back of the trunk and resides over the posterior surface of ribs two to seven.

Gregory, 1911), but until recently, little was known about the timing of appearance of various characters of the tetrapod limb. Dog anatomy comprises the anatomical studies of the visible parts of the body of a domestic dog.Details of structures vary tremendously from breed to breed, more than in any other animal species, wild or domesticated, as dogs are highly variable in height and weight. The growth of the humerus of feliforms is allometric and size plays an important role in the morphological differences between feliform taxa.

It originates from the lateral epicondyle of the humerus, crosses the back of the elbow joint on the same side, attaches to the lateral surface of the olecranon process and the adjacent surface of the ulna. Down syndrome: nasal bone hypoplasia has emerged as one of the strongest morphological markers of trisomy 21 to date.
