Hip Dysplasia
Hip dysplasia is an abnormality of the hip joint where the socket portion does not fully cover the ball portion, resulting in an increased risk for joint dislocation. Hip dysplasia may occur at birth or develop in early life. Regardless, it does not typically produce symptoms in babies less than a year old. Occasionally one leg may be shorter than the other. The left hip is more often affected than the right. Complications without treatment can include arthritis, limping, and low back pain. Females are affected more often than males. Risk factors for hip dysplasia include female sex, family history, certain swaddling practices, and breech presentation whether an infant is delivered vaginally or by cesarean section. If one identical twin is affected, there is a 40% risk the other will also be affected. Screening all babies for the condition by physical examination is recommended. Ultrasonography may also be useful. Many of those with mild instability resolve without specific t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pediatrics
Pediatrics (American English) also spelled paediatrics (British English), is the branch of medicine that involves the medical care of infants, children, Adolescence, adolescents, and young adults. In the United Kingdom, pediatrics covers many of their youth until the age of 18. The American Academy of Pediatrics recommends people seek pediatric care through the age of 21, but some pediatric subspecialists continue to care for adults up to 25. Worldwide age limits of pediatrics have been trending upward year after year. A physician, medical doctor who specializes in this area is known as a pediatrician, or paediatrician. The word ''pediatrics'' and its cognates mean "healer of children", derived from the two Ancient Greek, Greek words: (''pais'' "child") and (''iatros'' "doctor, healer"). Pediatricians work in clinics, research centers, universities, general hospitals and children's hospitals, including those who practice pediatric subspecialties (e.g. neonatology requires reso ...

Hip Replacements
Hip replacement is a surgical procedure in which the hip joint is replaced by a prosthetic implant, that is, a hip prosthesis. Hip replacement surgery can be performed as a total replacement or a hemi/semi(half) replacement. Such joint replacement orthopaedic surgery is generally conducted to relieve arthritis pain or in some hip fractures. A total hip replacement (total hip arthroplasty) consists of replacing both the acetabulum and the femoral head while hemiarthroplasty generally only replaces the femoral head. Hip replacement is one of the most common orthopaedic operations, though patient satisfaction varies widely between different techniques and implants. Approximately 58% of total hip replacements are estimated to last 25 years. The average cost of a total hip replacement in 2012 was $40,364 in the United States (€37,307.44 in euros), and about $7,700 to $12,000 in most European countries. NOTE: In euros, that is from €7,116.92 to €11,091.30 euros. Medical uses Tota ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chinese People
The Chinese people, or simply Chinese, are people or ethnic groups identified with Greater China, China, usually through ethnicity, nationality, citizenship, or other affiliation. Chinese people are known as Zhongguoren () or as Huaren () by speakers of standard Chinese, including those living in Greater China as well as overseas Chinese. Although both terms both refer to Chinese people, their usage depends on the person and context. The former term is commonly (but not exclusively) used to refer to the citizens of the People's Republic of China—especially mainland China. The term Huaren is used to refer to ethnic Chinese, and is more often used for those who reside overseas or are non-citizens of China. The Han Chinese are the largest ethnic group in China, comprising approximately 92% of its Mainland China, Mainland population.

African Americans
African Americans, also known as Black Americans and formerly also called Afro-Americans, are an American racial and ethnic group that consists of Americans who have total or partial ancestry from any of the Black racial groups of Africa. African Americans constitute the second largest ethno-racial group in the U.S. after White Americans. The term "African American" generally denotes descendants of Africans enslaved in the United States. In 2023, an estimated 48.3 million people self-identified as Black, making up 14.4% of the country’s population. This marks a 33% increase since 2000, when there were 36.2 million Black people living in the U.S. African-American history began in the 16th century, with Africans being sold to European slave traders and transported across the Atlantic to the Western Hemisphere. They were sold as slaves to European colonists and put to work on plantations, particularly in the southern colonies. A few were able to achieve freedom th ...

Afrikaners
Afrikaners () are a Southern African ethnic group descended from predominantly Dutch people, Dutch Settler colonialism, settlers who first arrived at the Cape of Good Hope in Free Burghers in the Dutch Cape Colony, 1652.Entry: Cape Colony. ''Encyclopædia Britannica Volume 4 Part 2: Brain to Casting''. Encyclopædia Britannica, Inc. 1933. James Louis Garvin, editor. Until 1994, they dominated South Africa's politics as well as the country's commercial agricultural sector. Afrikaans, a language which evolved from the Hollandic Dutch, Dutch dialect of South Holland, is the First language, mother tongue of Afrikaners and most Cape Coloureds. According to the 2022 South African census, South African National Census of 2022, 10.6% of South Africans claimed to speak Afrikaans as a first language at home, making it the country's third-largest home language after Zulu language, Zulu and Xhosa language, Xhosa.

Coxa Valga
Coxa valga is a deformity of the hip where the angle formed between the head and neck of the femur and its shaft is increased, usually above 135 degrees. The deformity may develop in children with neuromuscular disorders (i.e. cerebral palsy, spinal dysraphism, poliomyelitis), skeletal dysplasias, and juvenile idiopathic arthritis. Coxa valga deformity is a common pathologic condition in children with cerebral palsy, and they may be predisposed to hip subluxation or dislocations. See also * Coxa vara *Genu valgum *Genu varum Genu varum (also called bow-leggedness, bandiness, bandy-leg, and tibia vara) is a varus deformity marked by (outward) bowing at the knee, which means that the lower leg is angled inward ( medially) in relation to the thigh's axis, giving th ...

Femur Head
The femoral head (femur head or head of the femur) is the highest part of the thigh bone (femur). It is supported by the femoral neck. Structure The head is globular and forms rather more than a hemisphere, is directed upward, medialward, and a little forward, the greater part of its convexity being above and in front. The femoral head's surface is smooth. It is coated with cartilage in the fresh state, except over an ovoid depression, the fovea capitis, which is situated a little below and behind the center of the femoral head, and gives attachment to the ligament of head of femur. The thickest region of the articular cartilage is at the centre of the femoral head, measuring up to 2.8 mm. The diameter of the femoral head is usually larger in men than in women. Fovea capitis The fovea capitis is a small, concave depression within the head of the femur that serves as an attachment point for the ligamentum teres (Saladin). It is slightly ovoid in shape and is oriented "su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coxa Vara
Coxa vara is a deformity of the hip, whereby the angle between the head and the shaft of the femur is reduced to less than 120 degrees. This results in the leg being shortened and the development of a limp. It may be congenital and is commonly caused by injury, such as a fracture. It can also occur when the bone tissue in the neck of the femur is softer than normal, causing it to bend under the weight of the body. This may either be congenital or the result of a bone disorder. The most common cause of coxa vara is either congenital or developmental. Other common causes include metabolic bone diseases (e.g. Paget's disease of bone), post-Perthes deformity, osteomyelitis, and post traumatic (due to improper healing of a fracture between the greater and lesser trochanter). Shepherd's Crook deformity is a severe form of coxa vara where the proximal femur is severely deformed with a reduction in the neck shaft angle beyond 90 degrees. It is most commonly a sequela of osteogenes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acetabulum
The acetabulum (; : acetabula), also called the cotyloid cavity, is a wikt:concave, concave surface of the pelvis. The femur head, head of the femur meets with the pelvis at the acetabulum, forming the Hip#Articulation, hip joint. Structure There are three bones of the ''os coxae'' (hip bone) that come together to form the ''acetabulum''. Contributing a little more than two-fifths of the structure is the ischium, which provides lower and side boundaries to the acetabulum. The Ilium (bone), ilium forms the upper boundary, providing a little less than two-fifths of the structure of the acetabulum. The rest is formed by the Pubis (bone), pubis, near the midline. It is bounded by a prominent uneven rim, thick and strong on top, which serves as the point of attachment for the acetabular labrum. The acetabular labrum reduces the size of the opening of the acetabulum and deepens the surface of the hip joint. At the lower part of the acetabulum is the acetabular notch, which is continuo ...

Teratology
Teratology is the study of abnormalities of physiological development in organisms during their life span. It is a sub-discipline in medical genetics which focuses on the classification of congenital abnormalities in dysmorphology caused by teratogens and also in pharmacology and toxicology. Teratogens are substances that may cause non-heritable birth defects via a toxic effect on an embryo or fetus. Defects include malformations, disruptions, deformations, and dysplasia that may cause stunted growth, delayed mental development, or other congenital disorders that lack structural malformations. These defects can be recognized prior to or at birth as well as later during early childhood. The related term developmental toxicity includes all manifestations of abnormal development that are caused by environmental insult. The extent to which teratogens will impact an embryo is dependent on several factors, such as how long the embryo has been exposed, the stage of development the ...
