Varus Deformity
A varus deformity is an excessive inward angulation ( medial angulation, that is, towards the body's midline) of the distal segment of a bone or joint. The opposite of varus is called valgus. The terms varus and valgus always refer to the direction that the distal segment of the joint points. For example, in a valgus deformity of the knee, the distal part of the leg below the knee is deviated ''outward, in relation to the femur,'' resulting in a '' knock-kneed'' appearance. Conversely, a ''varus'' deformity at the knee results in a '' bowlegged'' with the distal part of the leg deviated ''inward, in relation to the femur''. However, in relation to the mid-line of the body, the knee joint is deviated towards the mid-line. Terminology The terminology is made confusing by the etymology of these words. * The terms ''varus'' and ''valgus'' are both Latin, but confusingly, their Latin meanings conflict with their current usage. In current usage, as noted above, a varus deformity ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cubitus Varus
Cubitus varus is a varus deformity in which the extended forearm is deviated towards midline of the body. Cubitus varus is often referred to as "Gunstock deformity", due to the crooked nature of the healing. The "opposite" condition is cubitus valgus. Signs and symptoms Complications Instances in which the medial epicondyle of the distal humerus is malformed due to the initial fracture at the humeral endplate may result in subluxation (snapping) of the ulnar nerve over the medial epicondyle with active flexion and extension of the elbow. In such instances, conductance of the ulnar nerve may be compromised due to chronic irritation, potentially resulting in irreversible ulnar neuropathy. Causes A common cause is a supracondylar fracture of the humerus. It can be corrected via a corrective osteotomy of the humerus and either internal or external fixation of the bone until union.

Clubfoot
Clubfoot is a congenital or acquired defect where one or both feet are rotated inward and downward. Congenital clubfoot is the most common congenital malformation of the foot with an incidence of 1 per 1000 births. In approximately 50% of cases, clubfoot affects both feet, but it can present unilaterally causing one leg or foot to be shorter than the other. Most of the time, it is not associated with other problems. Without appropriate treatment, the foot deformity will persist and lead to pain and impaired ability to walk, which can have a dramatic impact on the quality of life. The exact cause is usually not identified. Both genetic and environmental factors are believed to be involved. There are two main types of congenital clubfoot: idiopathic (80% of cases) and secondary clubfoot (20% of cases). The idiopathic congenital clubfoot is a multifactorial condition that includes environmental, vascular, positional, and genetic factors. There appears to be hereditary component ...

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. List A * Ambe * Avascular necrosis or Osteonecrosis * Arthritis B * Bone spur (Osteophytes) C * Craniosynostosis * Coffin–Lowry syndrome * Copenhagen disease F * Fibrodysplasia ossificans progressiva * Fibrous dysplasia * Fong disease (or Nail–patella syndrome) * Fracture G * Giant cell tumor of bone * Greenstick fracture * Gout H * Hypophosphatasia * Hereditary multiple exostoses K * Klippel–Feil syndrome M * Metabolic bone disease * Multiple myeloma N * Nail–patella syndrome O * Osteitis * Osteitis deformans (or Paget's disease of bone) * Ost ...

Valgus Deformity
A valgus deformity is a condition in which the bone segment distal to a joint is angled outward, that is, angled laterally, away from the body's midline. The opposite deformation, where the twist or angulation is directed medially, toward the center of the body, is called varus. Knee arthritis with valgus knee Rheumatoid knee commonly presents as valgus knee. Osteoarthritis knee may also sometimes present with valgus deformity though varus deformity is common. Total knee arthroplasty (TKA) to correct valgus deformity is surgically difficult and requires specialized implants called constrained condylar knees. Examples * Ankle: ''talipes valgus'' (from Latin ''talus'' = ankle and ''pes'' = foot) – outward turning of the heel, resulting in a 'flat foot' presentation. * Elbows: '' cubitus valgus'' (from Latin ''cubitus'' = elbow) – forearm is angled away from the body. * Foot: ''pes valgus'' (from Latin ''pes'' = foot) – a medial deviation of the foot at subtalar join ...

Hallux Varus
Hallux varus, also commonly referred to as ''sandal gap'', is a clinical condition characterized by medial deviation of the great toe at the metatarsophalangeal joint. This condition, when acquired by adults, is usually caused by sports injury, surgical overcorrection of hallux valgus, or underlying causes such as arthritides. A sandal gap that is congential and not caused by an injury can be a normal variant, and can be visible on a pre-natal ultrasound as early as the second trimester. However, it is also considered to be a "soft sign" associated with an increased likelihood of a genetic abnormality, including Down's Syndrome, CLOVES syndrome, and at least forty other rare conditions. One 2011 study of the common morphological features in autistic children (sample size of n=421) found that 59% of the children in the study had a sandal gap, the most common morphological abnormality in the group. In places where modern shoes whose toe boxes are excessively narrow have not bee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plantar Flexion
Motion, the process of movement, is described using specific anatomical terms. Motion includes movement of organs, joints, limbs, and specific sections of the body. The terminology used describes this motion according to its direction relative to the anatomical position of the body parts involved. Anatomists and others use a unified set of terms to describe most of the movements, although other, more specialized terms are necessary for describing unique movements such as those of the hands, feet, and eyes. In general, motion is classified according to the anatomical plane it occurs in. ''Flexion'' and ''extension'' are examples of ''angular'' motions, in which two axes of a joint are brought closer together or moved further apart. ''Rotational'' motion may occur at other joints, for example the shoulder, and are described as ''internal'' or ''external''. Other terms, such as ''elevation'' and ''depression'', describe movement above or below the horizontal plane. Many anatomic ...

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 the limb overall the appearance of an archer's bow. Usually medial angulation of both lower limb bones ( fibula and tibia) is involved. Causes If a child is sickly, either with rickets or any other ailment that prevents ossification of the bones or is improperly fed, the bowed condition may persist. Thus the chief cause of this deformity is rickets. Skeletal problems, infection, and tumors can also affect the growth of the leg, sometimes giving rise to a one-sided bow-leggedness. The remaining causes are occupational, especially among jockeys, and from physical trauma, the condition being very likely to supervene after accidents involving the condyles of the femur. Childhood Children until the age of 3 to 4 have a degree of genu varum ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cubitus Valgus
Cubitus valgus is a medical deformity in which the forearm is angled away from the body to a greater degree than normal when fully extended. A small degree of cubitus valgus (known as the carrying angle) is acceptable and occurs in the general population. When present at birth, it can be an indication of Turner syndromeChapter on Amenorrhea in: or Noonan syndrome. It can also be acquired through fracture or other trauma. The physiological cubitus valgus varies from 3° to 29°. Women usually have a more pronounced Cubitus valgus than men. The deformity can also occur as a complication of fracture of the lateral condyle of the humerus, which may lead to tardy/delayed ulnar nerve palsy. The opposite condition is cubitus varus ().

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] |
