Bone

The framework upon which the rest of the body is built up. The bones are generally called the skeleton, though this term also includes the cartilages which join the ribs to the breastbone, protect the larynx, etc.

Structure of bone Bone is composed partly of ?brous tissue, partly of bone matrix comprising phosphate and carbonate of lime, intimately mixed together. The bones of a child are about two-thirds ?brous tissue, whilst those of the aged contain one-third; the toughness of the former and the brittleness of the latter are therefore evident.

The shafts of the limb bones are composed of dense bone, the bone being a hard tube surrounded by a membrane (the periosteum) and enclosing a fatty substance (the BONE MARROW); and of cancellous bone, which forms the short bones and the ends of long bones, in which a ?ne lace-work of bone ?lls up the whole interior, enclosing marrow in its meshes. The marrow of the smaller bones is of great importance. It is red in colour, and in it red blood corpuscles are formed. Even the densest bone is tunnelled by ?ne canals (Haversian canals) in which run small blood vessels, nerves and lymphatics, for the maintenance and repair of the bone. Around these Haversian canals the bone is arranged in circular plates called lamellae, the lamellae being separated from one another by clefts, known as lacunae, in which single bone-cells are contained. Even the lamellae are pierced by ?ne tubes known as canaliculi lodging processes of these cells. Each lamella is composed of very ?ne interlacing ?bres.

GROWTH OF BONES Bones grow in thickness from the ?brous tissue and lime salts laid down by cells in their substance. The long bones grow in length from a plate of cartilage (epiphyseal cartilage) which runs across the bone about 1·5 cm or more from its ends, and which on one surface is also constantly forming bone until the bone ceases to lengthen at about the age of 16 or 18. Epiphyseal injury in children may lead to diminished growth of the limb.

REPAIR OF BONE is e?ected by cells of microscopic size, some called osteoblasts, elaborating the materials brought by the blood and laying down strands of ?brous tissue, between which bone earth is later deposited; while other cells, known as osteoclasts, dissolve and break up dead or damaged bone. When a fracture has occurred, and the broken ends have been brought into contact, these are surrounded by a mass of blood at ?rst; this is partly absorbed and partly organised by these cells, ?rst into ?brous tissue and later into bone. The mass surrounding the fractured ends is called the callus, and for some months it forms a distinct thickening which is gradually smoothed away, leaving the bone as before the fracture. If the ends have not been brought accurately into contact, a permanent thickening results.

VARIETIES OF BONES Apart from the structural varieties, bones fall into four classes: (a) long bones like those of the limbs; (b) short bones composed of cancellous tissue, like those of the wrist and the ankle; (c) ?at bones like those of the skull; (d) irregular bones like those of the face or the vertebrae of the spinal column (backbone).

The skeleton consists of more than 200 bones. It is divided into an axial part, comprising the skull, the vertebral column, the ribs with their cartilages, and the breastbone; and an appendicular portion comprising the four limbs. The hyoid bone in the neck, together with the cartilages protecting the larynx and windpipe, may be described as the visceral skeleton.

AXIAL SKELETON The skull consists of the cranium, which has eight bones, viz. occipital, two parietal, two temporal, one frontal, ethmoid, and sphenoid; and of the face, which has 14 bones, viz. two maxillae or upper jaw-bones, one mandible or lower jaw-bone, two malar or cheek bones, two nasal, two lacrimal, two turbinal, two palate bones, and one vomer bone. (For further details, see SKULL.) The vertebral column consists of seven vertebrae in the cervical or neck region, 12 dorsal vertebrae, ?ve vertebrae in the lumbar or loin region, the sacrum or sacral bone (a mass formed of ?ve vertebrae fused together and forming the back part of the pelvis, which is closed at the sides by the haunch-bones), and ?nally the coccyx (four small vertebrae representing the tail of lower animals). The vertebral column has four curves: the ?rst forwards in the neck, the second backwards in the dorsal region, the third forwards in the loins, and the lowest, involving the sacrum and coccyx, backwards. These are associated with the erect attitude, develop after a child learns to walk, and have the e?ect of diminishing jars and shocks before these reach internal organs. This is aided still further by discs of cartilage placed between each pair of vertebrae. Each vertebra has a solid part, the body in front, and behind this a ring of bone, the series of rings one above another forming a bony canal up which runs the spinal cord to pass through an opening in the skull at the upper end of the canal and there join the brain. (For further details, see SPINAL COLUMN.) The ribs – 12 in number, on each side – are attached behind to the 12 dorsal vertebrae, while in front they end a few inches away from the breastbone, but are continued forwards by cartilages. Of these the upper seven reach the breastbone, these ribs being called true ribs; the next three are joined each to the cartilage above it, while the last two have their ends free and are called ?oating ribs. The breastbone, or sternum, is shaped something like a short sword, about 15 cm (6 inches) long, and rather over 2·5 cm (1 inch) wide.

APPENDICULAR SKELETON The upper limb consists of the shoulder region and three segments – the upper arm, the forearm, and the wrist with the hand, separated from each other by joints. In the shoulder lie the clavicle or collar-bone (which is immediately beneath the skin, and forms a prominent object on the front of the neck), and the scapula or shoulder-blade behind the chest. In the upper arm is a single bone, the humerus. In the forearm are two bones, the radius and ulna; the radius, in the movements of alternately turning the hand palm up and back up (called supination and pronation respectively), rotating around the ulna, which remains ?xed. In the carpus or wrist are eight small bones: the scaphoid, lunate, triquetral, pisiform, trapezium, trapezoid, capitate and hamate. In the hand proper are ?ve bones called metacarpals, upon which are set the four ?ngers, each containing the three bones known as phalanges, and the thumb with two phalanges.

The lower limb consists similarly of the region of the hip-bone and three segments – the thigh, the leg and the foot. The hip-bone is a large ?at bone made up of three – the ilium, the ischium and the pubis – fused together, and forms the side of the pelvis or basin which encloses some of the abdominal organs. The thigh contains the femur, and the leg contains two bones – the tibia and ?bula. In the tarsus are seven bones: the talus (which forms part of the ankle joint); the calcaneus or heel-bone; the navicular; the lateral, intermediate and medial cuneiforms; and the cuboid. These bones are so shaped as to form a distinct arch in the foot both from before back and from side to side. Finally, as in the hand, there are ?ve metatarsals and 14 phalanges, of which the great toe has two, the other toes three each.

Besides these named bones there are others sometimes found in sinews, called sesamoid bones, while the numbers of the regular bones may be increased by extra ribs or diminished by the fusion together of two or more bones.... bone

Cibotium Tea

Altough Cibotium tea is not very popular and sometimes hard to find within the United States, it is worth trying, as it has many health benefits. About Cibotium Tea Cibotium is a genus of fern tropical tree - subject to much confusion and revision. There are approximately eleven species distributed in South Eastern Asia, Central America, Hawaii and Mexico. Amoung them, Cibotium barometz is well known and used in Asian medicine as it is belived to be a very powerful tonifying agent for the lungs and kidneys. The fronds of this fern are lacy and have a light green color. The trunk of the fern usually develops orange to brown hairs over time. For their part, the rhizomes or roots have long, soft, golden-yellow hair coverings and these have given it its nicknames such as “golden hair dog” or “yellow dog hair”. The rhizomes are the most used parts in traditional Chinese medicine. The cibotium rhizomes containe tannins, pigments, cibotiumbarosides A and B, as well as cibotiglycerol. Cibotium tea benefits can be felt if you take one cup, 2 to 3 times per day. Cibotium Tea drink For a tasty Cibotium tea you can use 2 to 4 grams of powdered rhizomes and dissolve them in a cup of newly-boiled water. Let them infuse for about 5 minutes and drink. Benefits of Cibotium Tea The following are the cibotium tea benefits attributed to this brew: It is believed to help expel “wind” and moisture and ease weakness. This tea is believed to help strengthen the sinews and the bones of the lower back. Cibotium tea, in combination with other herbs such as cinnamon twigs, is believed to help ease aches, pains and stiffness in the back and in the knees. Cibotium tea may fight chronic rheumatism. It may also be helpful in dizziness, tinnitus and blurred vision caused by yin deficiency in the kidney and liver, according to traditional Chinese medicine. Side effects of Cibotium Tea Generally, there are no known side-effects or drug interactions associated with Cibotium tea. However, patients who are dehydrated, or have a dry mouth, dark yellow/brown urine, or a bitter taste in the mouth should not use this type of tea. As always, consult with a qualified health care provider before taking cibotium or any other dietary supplement.   Cibotium tea is mostly safe for health and if you keep your moderation you can easily enjoy its benefits.... cibotium tea

Tendon

A tendon – also known as sinew, or leader – is the cord of tissue that attaches the end of a muscle to the bone or other structure upon which the muscle acts when it contracts. Tendons are composed of bundles of white ?brous tissue arranged in a very dense manner, and are of great strength. Some are rounded, some ?attened bands, whilst others are very short – the muscle-?bres being attached almost directly to the bone. Most tendons are surrounded by sheaths lined with membrane similar to the SYNOVIAL MEMBRANE lining joint-cavities: in this sheath the tendon glides smoothly over surrounding parts. The ?bres of a tendon pass into the substance of the bone and blend with the ?bres composing it. One of the largest tendons in the body is the Achilles tendon, or tendo calcaneus, which attaches the muscle of the calf to the calcaneus or heel-bone.

Tendon injuries are one of the hazards of sports (see SPORTS MEDICINE). They usually result from indirect violence, or overuse, rather than direct violence.

Rupture usually results from the sudden application of an unbalanced load. Thus, complete rupture of the Achilles tendon is common in taking an awkward step backwards playing squash. There is sudden pain; the victim is often under the impression that he or she has received a blow. This is accompanied by loss of function, and a gap may be felt in the tendon.

Partial Rupture is also accompanied by pain, but there is no breach of continuity or complete loss of function. Treatment of a complete rupture usually means surgical repair followed by immobilisation of the tendon in plaster of Paris for six weeks. Partial rupture usually responds to physiotherapy and immobilisation, but healing is slow.... tendon

Dupuytren’s Contracture

The Thatcher Finger. Fibrosis of the palm of the hand leading to deformity. Inability to straighten the ring and little finger due to fixed flexion. A tightened sinew. High serum fat levels are present, the disease affecting men from the age of 20 and women after the menopause.

“It is believed that oxidation of the lipids by free radicals (which are also present in high numbers in patients who have Dupuytren’s contracture) produces toxins which kill fibroblast cells in the palmar fascia. The surrounding tissue overreacts by producing many more fibroblasts, a bit like callous formation after a wound. The rapid increase in fibrous tissue leads to the contracture. This explains why the contracture is so common among patients with diabetes, epilepsy and alcoholism – serum lipid levels are raised in all these groups . . . However, the disorder occurs only if the patient has a genetic predisposition to the disease.” (Mr Paul Sanderson, Orthopaedic Surgeon, Wrightington Hospital, Wigan, in the Journal of Bone and Joint Surgery, Nov. 1992)

Treatment. Directed towards prevention. Same as for HYPERLIPIDAEMIA.
