Shoulder osteochondrosis is a disturbance of endochondral ossification in the humeral head cartilage, which may lead to a clinical problem, the appropriate term for which is "osteochondritis dissecans. The increase of epiphyseal volume, in growing animals, occurs through endochondral ossification within the epiphyseal cartilage.

Cerdeira J. Canine hip dysplasia is one of the most prevalent developmental orthopedic diseases in dogs worldwide. Unfortunately, the success of eradication programs against this disease based on radiographic diagnosis is low. Adding the use of diagnostic genetic tools to the current phenotype-based approach might be beneficial. The aim of this study was to develop a genetic prognostic test for early diagnosis of hip dysplasia in Labrador Retrievers. For each dog, a blood sample and a ventrodorsal hip radiograph were taken.
In dogs, hip dysplasia is an abnormal formation of the hip socket that, in its more severe form, can eventually cause lameness and arthritis of the joints. It is a genetic polygenic trait that is affected by environmental factors. It is common in many dog breeds, particularly the larger breeds, and is the most common single cause of arthritis of the hips. During growth, both the ball the head of the femur , or thighbone and the socket in the pelvis acetabulum must grow at equal rates. In hip dysplasia, this uniform growth during puppyhood does not occur.
Many diseases of the skeletal system are congenital in the sense that they become evident at or soon after birth. This does not imply that they all are genetically determined. Most are caused by factors operating during pregnancy, delivery, or early infancy. Intrauterine injuries of the skeletal system were dramatically seen in children born of some women who received thalidomide , a drug previously used to treat morning sickness, during the initial three months of pregnancy. These children suffered severe extremity defects such as shortened or malformed limbs phocomelia. Most intrauterine injuries are probably not caused by drugs, however, but perhaps by viral, hormonal, or mechanical factors. Intrauterine amputations, clubfoot, and congenital dislocation of the hip probably belong to this group.

Canine parvovirus CPV is a highly contagious viral disease of dogs that commonly causes acute gastrointestinal illness in puppies. The disease most often strikes in pups between six and 20 weeks old, but older animals are sometimes also affected. A rare variant of the disease may be seen in very young neonatal puppies is myocarditis an inflammation of the heart muscle.

Radiographic Signs of Joint Disease
Some joint diseases, such as arthritis, affect the joint membranes themselves. Other types of joint conditions affect the tendons, cartilage, bursae, and fluid within the joint. Joint disorders may be congenital present at birth or may be the result of injury to the joint, degeneration deterioration with loss of function , abnormal development, immune-related conditions, cancers, or infections. This deterioration of the top of the femur femoral head seen in young miniature and small breeds of dogs is characterized by a lack of blood supply and destruction of blood vessels of the bone. It is also known by the technical term, aseptic necrosis of the femoral head.
В один из прохладных осенних дней они сидели на стадионе, наблюдая за тем, как футбольная команда Рутгерса громит команду Джорджтауне кого университета. - Я забыла: как называется вид спорта, которым ты увлекаешься? - спросила Сьюзан. - Цуккини. - Сквош, - чуть не застонал Беккер. Сьюзан сделала вид, что не поняла.
