Brachymetacarpia
Brachymetacarpia or brachymetacarpalia is a medical condition in which the metacarpal bones of the hands are shortened. The equivalent condition in the foot is brachymetatarsia, in which the metatarsal bones are shortened. Brachymetacarpia is typically congenital and presents in childhood or early adolescence, but it can also be associated with other acquired syndromes or endocrinological conditions. While cosmetic appearance is the most common concern of affected individuals, brachymetacarpia may also affect hand function due to alterations in muscle and tendon length. Treatment usually involves lengthening of the affected bone(s), either acutely with a bone graft or gradually with an external fixator. This condition is one of the causes of brachydactyly Brachydactyly () is a medical term denoting the presence of abnormally short digits (fingers or toes) at birth. The shortness is relative to the length of other long bones and other parts of the body. Brachydactyly is an inh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metacarpal Bones
In human anatomy, the metacarpal bones or metacarpus, also known as the "palm bones", are the appendicular bones that form the intermediate part of the hand between the phalanges (fingers) and the carpal bones ( wrist bones), which articulate with the forearm. The metacarpal bones are homologous to the metatarsal bones in the foot. Structure The metacarpals form a transverse arch to which the rigid row of distal carpal bones are fixed. The peripheral metacarpals (those of the thumb and little finger) form the sides of the cup of the palmar gutter and as they are brought together they deepen this concavity. The index metacarpal is the most firmly fixed, while the thumb metacarpal articulates with the trapezium and acts independently from the others. The middle metacarpals are tightly united to the carpus by intrinsic interlocking bone elements at their bases. The ring metacarpal is somewhat more mobile while the fifth metacarpal is semi-independent.Tubiana ''et al'' 1998, p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brachymetatarsia
Brachymetatarsia is a rare malformation that causes one or more toes to be abnormally short. The condition is characterized by a Metatarsal bones, metatarsal arch shortness of more than 5 mm. The condition is more common in females, and the incidence reported in the literature ranges from 0.02% to 0.05%. Brachymetatarsia appears to be the result of epiphyseal plate retardation or premature closure. The etiology may be congenital and Idiopathic disease, idiopathic, posttraumatic, postinfection, Iatrogenesis, iatrogenic, or secondary to a systemic disease such as cancer, sickle cell disease, pseudohyperparathyroidism, Turner syndrome, Turner's syndrome, Down syndrome, Apert syndrome, athyroidism, or osteodystrophy. It most frequently involves the fourth Metatarsal bones, metatarsal. If it involves the first metatarsal, the condition is known as Morton's syndrome. Treatment is via a number of differing surgical procedures. Diagnosis Differential diagnosis Congenital causes include: ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metatarsal Bones
The metatarsal bones or metatarsus (: metatarsi) are a group of five long bones in the midfoot, located between the tarsal bones (which form the heel and the ankle) and the phalanges ( toes). Lacking individual names, the metatarsal bones are numbered from the medial side (the side of the great toe): the first, second, third, fourth, and fifth metatarsal (often depicted with Roman numerals). The metatarsals are analogous to the metacarpal bones of the hand. The lengths of the metatarsal bones in humans are, in descending order, second, third, fourth, fifth, and first. A bovine hind leg has two metatarsals. Structure The five metatarsals are dorsal convex long bones consisting of a shaft or body, a base ( proximally), and a head ( distally).Platzer 2004, p. 220 The body is prismoid in form, tapers gradually from the tarsal to the phalangeal extremity, and is curved longitudinally, so as to be concave below, slightly convex above. The base or posterior extremity is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birth Defect
A birth defect is an abnormal condition that is present at birth, regardless of its cause. Birth defects may result in disabilities that may be physical, intellectual, or developmental. The disabilities can range from mild to severe. Birth defects are divided into two main types: structural disorders in which problems are seen with the shape of a body part and functional disorders in which problems exist with how a body part works. Functional disorders include metabolic and degenerative disorders. Some birth defects include both structural and functional disorders. Birth defects may result from genetic or chromosomal disorders, exposure to certain medications or chemicals, or certain infections during pregnancy. Risk factors include folate deficiency, drinking alcohol or smoking during pregnancy, poorly controlled diabetes, and a mother over the age of 35 years old. Many birth defects are believed to involve multiple factors. Birth defects may be visible at birth or dia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
External Fixation
External fixation is a surgical treatment wherein Kirschner wire, Kirschner pins and wires are inserted and affixed into bone and then exit the body to be attached to an external apparatus composed of rings and threaded rods — the Ilizarov apparatus, the Taylor Spatial Frame, and the Octopod External Fixator — which immobilises the damaged limb to facilitate healing. As an alternative to internal fixation, wherein bone-stabilising mechanical components are surgically emplaced in the body of the patient, external fixation is used to stabilize bone tissues and soft tissues at a distance from the site of the injury. History In Classical Greece, the physician Hippocrates described an external fixation apparatus composed of leather rings connected with four wooden rods from a Cornel tree to splint the fracture of a tibia, tibia bone. In 1840, Jean-Francois Malgaigne described a spike driven into the tibia and held by straps to immobilise a fractured tibia. In 1843 he used a claw ...

Brachydactyly
Brachydactyly () is a medical term denoting the presence of abnormally short digits (fingers or toes) at birth. The shortness is relative to the length of other long bones and other parts of the body. Brachydactyly is an inherited, dominant trait. It most often occurs as an isolated dysmelia, but can also occur with other anomalies as part of many congenital syndromes. Brachydactyly may also be a signal that one is at risk for congenital heart disease due to the association between congenital heart disease and Carpenter syndrome and the link between Carpenter syndrome and brachydactyly. Nomograms for normal values of finger length as a ratio to other body measurements have been published.

Skeletal Disorders
Bone disease refers to the medical conditions which affect the bone. Terminology A bone disease is also called an "osteopathy", but because the term osteopathy is often used to refer to an alternative health-care philosophy, use of the term can cause some confusion. Bone and cartilage disorders Osteochondrodysplasia is a general term for a disorder of the development of bone and cartilage.
