Hand

In structure, the hand has a bony basis of eight small carpal bones in the wrist, ?ve metacarpal bones in the ?eshy part of the hand, and three phalanges in each ?nger – two only in the thumb. From the muscles of the forearm, 12 strong tendons run in front of the wrist. Of these, nine go to the ?ngers and thumb and are bound down by a strong band, the ?exor retinaculum, in front of the wrist. They are enclosed in a complicated synovial sheath, and pass through the palm and down the ?ngers. Behind the wrist, 12 tendons likewise cross from forearm to hand.

Forming the ball of the thumb and that of the little ?nger, and ?lling up the gaps between the metacarpal bones, are other muscles, which act to separate and bring together the ?ngers, and to bend them at their ?rst joints (knuckles).... hand

Handicap

A disadvantage for a given individual, resulting from an impairment or a disability that limits or prevents the fulfilment of a role that is normal (depending on age, sex and social and cultural practice) for that individual. The term handicap thus reflects interaction with, and adaptation to, the individual’s surroundings. See also “disability”; “impairment”.... handicap

Claw-hand

A (contraction) deformity of the hand and ?ngers, especially of the ring and little ?ngers. The condition is generally due to paralysis of the ULNAR NERVE. A somewhat similar condition is produced by contraction of the ?brous tissues in the palm of the hand, partly due to rheumatic changes and partly to injury caused by the constant pressure of a tool against the palm of the hand. (See DUPUYTREN’S CONTRACTURE.)... claw-hand

Hand, Foot And Mouth Disease

A contagious disease due to infection with coxsackie A16 virus (see COXSACKIE VIRUSES). Most common in children, the incubation period is 3–5 days. It is characterised by an eruption of blisters on the palms and the feet (often the toes), and in the mouth. The disease

has no connection with foot and mouth disease in cattle, deer, pigs and sheep.... hand, foot and mouth disease

Chapped Hands

Chapped hands occur in cold weather, when reduced sweat and sebaceous activity leads to decreased natural protection of the skin. Prolonged immersion in soapy water, followed by exposure to cold air, results in cracking of the skin.

Prevention consists of minimising exposure to detergents and soapy water, and wearing rubber gloves for all routine household duties.... chapped hands

Cleft Palate

A ?ssure in the roof of the mouth (palate) and/ or the lip which is present at birth. It is found in varying degrees of severity in about one in 700 children. Modern plastic surgery can greatly improve the functioning of lips and palate and the appearance of the baby. Further cosmetic surgery later may not be necessary. The parent of the child who has cleft lip and/ or palate will be given detailed advice speci?c to his or her case. In general the team of specialists involved are the paediatrician, plastic surgeon, dentist or orthodontic specialist, and speech therapist. (See PALATE, MALFORMATIONS OF.)... cleft palate

Handedness

Preference for using the right or left hand. Some 90 per cent of adults use the right hand for writing; two thirds prefer the right hand for most activities requiring coordination and skill. The others are either lefthanded or ambidextrous (able to use both hands equally well).

Handedness is related to the division of the brain into 2 hemispheres, each of which controls movement and sensation on the opposite side of the body.

In most right-handed people the speech centre is in the left brain hemisphere.

Inheritance is probably the most important factor in determining handedness.... handedness

Cleft Foot

A rare congenital abnormality characterised by the absence of one or more toes and a deep central cleft that divides the foot into two. It is sometimes known as lobster foot, or lobster claw. It may be accompanied by other congenital defects, such as CLEFT HAND, absent permanent teeth, CLEFT PALATE (and/or lip), absence of the nails, and defects of the eye.... cleft foot

Hand–arm Vibration Syndrome

Pain and numbness in the hand and arm due to prolonged use of vibrating tools. Symptoms often also include blue or white coloration of the fingers and a tingling sensation in affected areas. Hand–arm vibration syndrome tends to develop slowly over years and is the result of repeated damage to blood vessels and nerves. Exposure to cold tends to aggravate the condition. There is no specific treatment, but avoiding vibrating tools is essential to prevent the disease progressing. In some cases, calcium channel blockers may help relieve some symptoms.... hand–arm vibration syndrome

Shoulder–hand Syndrome

Pain and stiffness affecting one shoulder and the hand on the same side; the hand may also become hot, sweaty, and swollen. Arm muscles may waste through lack of use (see Sudeck’s atrophy). The cause of shoulder–hand syndrome is unknown, but it may occur as a complication of myocardial infarction, stroke, herpes zoster, or shoulder injury. Recovery usually occurs in about 2 years. This period may be shortened by physiotherapy and corticosteroid drugs. In rare cases, a cervical sympathectomy is performed.... shoulder–hand syndrome

Cleft Lip And Palate

A split in the upper lip and/or palate that is present at birth. Cleft lip is a vertical, usually off-centre split in the upper lip that may be a small notch or may extend to the nose. The upper gum may also be cleft, and the nose may be crooked. The term

hare lip refers only to a midline cleft lip, which is rare. Cleft palate is a gap that may extend from the back of the palate to behind the teeth and be open to the nasal cavity. Cleft palate is often accompanied by partial deafness and there may be other birth defects.

Surgery to repair a cleft lip may be undertaken in the first few days after birth or at about 3 months.

It improves appearance; after repair, speech defects are rare.

A cleft palate is usually repaired at about 12 months, but further surgery, orthodontic treatment, and speech therapy may be required.... cleft lip and palate
