Stellate Fracture: From 1 Different Sources
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).
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
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 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

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

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 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
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.

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

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.

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
