Greenstick Fracture

An incomplete fracture, in which the bone is not completely broken across. It occurs in the long bones of children and is usually due to indirect force. (See BONE, DISORDERS OF – Bone fractures.)... greenstick fracture

March Fracture

A curious condition in which a fracture occurs of the second (rarely, the third) metatarsal bone in the foot without any obvious cause. The usual story is that a pain suddenly developed in the foot while walking or marching (hence the name), and that it has persisted ever since. The only treatment needed is immobilisation of the foot and rest, and the fracture heals satisfactorily. (For more information on fractures, see BONE, DISORDERS OF – Bone fractures.)... march fracture

Colles’ Fracture

Colles’ fracture is a fracture of the lower end of the radius close to the wrist, caused usually by a fall forwards on the palm of the hand, in which the lower fragment is displaced backwards. (See BONE, DISORDERS OF.)... colles’ fracture

Fracture

A break in a bone, usually across its width. There are 2 main types: closed (simple) or open (compound) fractures. In a closed fracture, the broken bone ends remain beneath the skin and little surrounding tissue is damaged; in an open fracture, 1 or both bone ends project through the skin. If the bone ends are not aligned, the fracture is termed “displaced”. Fractures can be further divided according to the pattern of the break, for example, transverse or spiral fractures of long bones. In a greenstick fracture, the break is not through the full width of the bone. This type of fracture occurs only in children because their bones are more pliable. In an avulsion fracture, a small piece of bone is pulled off by a tendon.Most fractures are the result of a fall, but in osteoporosis the bone is weakened, and fractures such as compression fractures of the vertebrae are common.

Common sites of fracture include the hand, wrist (see Colles’ fracture), ankle joint, clavicle, and the neck of the femur (see femur, fracture of). There is usually swelling and tenderness at the fracture site. The pain is often severe and is usually made worse by movement.

X-rays can confirm a fracture. Because bone begins to heal soon after it has broken, the first aim of treatment is to ensure that the bone ends are aligned. Displaced bone ends are manoeuvred

back into position, under general anaesthetic, by manipulation either through the skin or through an incision. The bone is then immobilized. In some cases the ends of the bone may be fixed with metal pins or plates.

Most fractures heal without any problems. Healing is sometimes delayed because the blood supply to the affected bone is inadequate (as a result of damaged blood vessels) or because the bone ends are not close enough together. If the fracture fails to unite, internal fixation or a bone graft may be needed. Osteomyelitis is a possible complication of open fractures.

Stress Fracture

A fracture that occurs as a result of repetitive jarring of a bone. Common sites include the metatarsal bones in the foot (see March fracture), the tibia or fibula, the neck of the femur, and the lumbar spine. The main symptoms are pain and tenderness at the fracture site. Diagnosis is by bone imaging. Treatment consists of resting the affected area for 4–6 weeks. The fracture may be immobilized in a cast.... stress fracture

Pott’s Fracture

A variety of fractures around the ankle, accompanied by a varying degree of dislocation of the ankle. In all cases the ?bula is fractured. Named after Percivall Pott, who suffered from this fracture and was the ?rst to describe it (see BONE, DISORDERS OF), it is often mistaken for a simple sprain of the ankle.... pott’s fracture

Stress Fractures

Stress fractures are comparatively common in sportspeople. They tend to occur when an undue amount of exercise is taken – that is, an amount of exercise which an individual is not capable of coping with in his or her state of training. The main initial feature is pain over the affected bone that has been subjected to abnormal physical stress. This is usually insidious in onset, and worse at night and during and after exercise. It is accompanied by tenderness, and a lump may be felt over the affected site. X-ray evidence only appears after several weeks. Treatment consists of rest, some form of external support, and in the initial stage ANALGESICS to deaden or kill the pain. (See also BONE, DISORDERS OF – Bone fractures.)... stress fractures

Colles’ Fracture

A break in the radius (one of the lower-arm bones) just above the wrist, in which the wrist and hand are displaced backwards, restricting movement and causing swelling and severe pain.

The fracture is usually the result of putting out a hand to lessen the impact of a fall.

The broken bones are manipulated back into position, and set in a cast.

Healing takes up to 6 weeks.

Hand and wrist movements usually return to normal, but there may be minor wrist deformity.... colles’ fracture

Femur, Fracture Of

The symptoms, treatment, and possible complications of a fracture of the femur (thigh-bone) depend on whether the bone has broken across its neck (the short section between the top of the shaft and the hip joint) or across the shaft.Fracture of the neck of the femur, often called a broken hip, is very common in elderly people, especially in women with osteoporosis, and is usually associated with a fall. In a fracture of the neck of the femur, the broken bone ends are often considerably displaced; in such cases there is usually severe pain in the hip and groin, making standing impossible. Occasionally, the broken ends become impacted. In this case, there is less pain and walking may be possible. Diagnosis is confirmed by X-ray. If the bone ends are displaced, an operation under general anaesthesia is necessary, either to realign the bone ends and to fasten them together, or to replace the entire head and neck of the femur with an artificial substitute (see hip replacement). If the bone ends are impacted the fracture may heal naturally, but surgery may still be recommended to avoid the need for bed rest.

Complications include damage to the blood supply to the head of the femur, causing it to disintegrate. Osteoarthritis may develop in the hip joint after fracture of the femur neck itself. However, immobility and the need for surgery in the elderly may result in complications, such as pneumonia, that are not directly related to the fracture site.

Fracture of the bone shaft usually occurs when the femur is subjected to extreme force, such as that which occurs in a traffic accident. In most cases, the bone ends are considerably displaced, causing severe pain, tenderness, and swelling.

Diagnosis is confirmed by X-ray. With a fractured femoral shaft there is often substantial blood loss from the bone. In most cases, the fracture is repaired by surgery in which the ends of the bone are realigned and fastened together with a metal pin. Sometimes the bone ends can be realigned by manipulation, and surgery is not necessary. After realignment, the leg is supported with a splint and put in traction to hold the bone together while it heals.

Complications include failure of the bone ends to unite or fusion of the broken ends at the wrong angle, infection of the bone, or damage to a nerve or artery.

A fracture of the lower shaft can cause permanent stiffness of the knee.... femur, fracture of

Fracture, Dental

A break in a tooth (see teeth) most commonly caused by falling onto a hard surface or by being hit in the mouth with a hard object.

Fractures may involve the crown or the root of a tooth, or both.

Fractures of the enamel can usually be repaired by bonding (see bonding, dental); in some cases, a replacement crown may be fitted (see crown, dental).

Pulpotomy may be performed if the pulp of a tooth is damaged.

Fractures of the root may be treated by splinting (see splinting, dental), root-canal treatment, or removing the tooth (see extraction, dental).... fracture, dental

’s Humerus, Fracture Of

The humerus is most commonly fractured at its neck (the upper end of the shaft, below the head), particularly in elderly people. Fractures of the shaft occur in adults of all ages. Fractures of the lower humerus occur most commonly in children.An X-ray can show a fracture of the humerus. A fracture of the bone’s neck usually requires only a sling to immobilize the bone; a fracture of the shaft or lower bone normally needs a plaster cast. Most fractures of the humerus heal in 6–8 weeks.... ’s humerus, fracture of

Jaw, Fractured

A fracture of the jaw, most often caused by a direct blow. A minor fracture may cause tenderness, pain on biting, and stiffness. In more severe injuries, teeth may be loosened or damaged, jaw movement may be severely limited, and there may be loss of feeling in the lower lip. Minor fractures are normally left to heal on their own. For severe fractures with displacement of the bones, surgical treatment is necessary. To allow healing, the jaw is immobilized, usually by wiring the upper

and lower teeth together. The wires are removed after about 6 weeks.... jaw, fractured

Monteggia’s Fracture

Fracture of the ulna just below the elbow, with dislocation of the radius from the elbow joint.... monteggia’s fracture

Rib, Fracture Of

Fracture of a rib may be caused by a fall or blow, or by stress on the ribcage, such as that produced by prolonged coughing.

The fracture of a rib causes severe pain, which may be relieved by analgesic drugs or by an injection of a local anaesthetic.... rib, fracture of

Skull, Fracture Of

A break in 1 or more of the skull bones caused by a head injury. In most skull fractures, the broken bones are not displaced and there are no complications. Severe injury may result in bone fragments rupturing blood vessels in the meninges, or, more rarely, tearing the meninges, leading to brain damage.

A fracture without complications usually heals by itself; damage to brain structures often requires neurosurgery.... skull, fracture of

Cervical Fracture

a fracture of a vertebra in the neck (see cervical vertebrae). Cervical fractures range from minor, requiring no treatment, to those associated with paralysis and instant death. Treatment can be support with a collar, skull traction, an *orthosis attached to the skull, or surgery, depending on the severity of the fracture.... cervical fracture

Fatigue Fracture

Pathological Fracture

a fracture through diseased or abnormal bone, usually resulting from a force insufficient to fracture a normal bone. Tumour, infection, congenital bone defects, and osteoporosis are among the causes.... pathological fracture

Penile Fracture

Pott’s Disease

*tuberculosis of the backbone. Untreated, it can lead to a hunchback deformity. Treatment is antituberculous chemotherapy and occasionally surgery. [P. Pott (1714–88), British surgeon]... pott’s disease

Smith’s Fracture

a fracture just above the wrist, across the distal (far) end of the radius, resulting in volar (forward) displacement of the hand and wrist below the fracture. It is the reverse of *Colles’ fracture. [R. W. Smith (1807–73), Irish surgeon]... smith’s fracture

Ulna, Fracture Of

A fracture of the ulna, 1 of the 2 bones of the forearm. Ulnar fractures typically occur across the shaft or at the olecranon process.

A fracture to the shaft usually results from a blow to the forearm or a fall onto the hand. Sometimes the radius is fractured at the same time (see radius, fracture of). Surgery is usually needed to reposition the broken bone ends and fix them together using either a plate and screws or a long nail down the centre of the bone. The arm is immobilized in a cast, with the elbow at a rightangle, until the fracture heals.

A fracture of the olecranon process is usually the result of a fall onto the elbow. If the bone ends are not displaced, the arm is immobilized in a cast that holds the elbow at a rightangle. If the bone ends are displaced, however, they are fitted together and fixed with a metal screw.... ulna, fracture of

Scaphoid Fracture

a fracture of the scaphoid bone in the wrist, usually caused by a fall onto the outstretched hand. There is pain and swelling in the *anatomical snuffbox and movements of the wrist and thumb are painful. If the fracture is suspected but not initially visible on X-ray, advanced imaging (a bone scan, CT scan, or MRI) is now increasingly used to confirm the diagnosis without delay. Treatment is with a cast for an undisplaced fracture and by internal fixation for a displaced fracture. Due to the anatomy of its blood supply, healing can take a long time, and a *bone graft and internal fixation may be required for non-*union.... scaphoid fracture

Stellate Fracture

a star-shaped fracture of the kneecap caused by a direct blow. The bone may be either split or severely shattered; if the fragments are displaced, the bone may need to be surgically repaired or rarely removed (patellectomy).... stellate fracture
