Structure and function of the foot

Foot - is the final leg department, a person performs a support function, and spring. Conditional border of the foot, separating it from the lower leg is a line drawn across the top of the ankle. At the foot there are three main areas: the tarsus, metatarsus and fingers.

Tarsus is situated behind and consists of seven bones: the talus, calcaneal navicular, cuboid, and three wedge. Before the tarsus is metatarsus consists of five bones. Metatarsals tubular, short, they connect to the tarsus and phalanges are the basis of the mid-foot. Each has two metatarsal heads (they are part of the joint), the two neck and body. Phalanges - a forefoot, II-V fingers are made up of three bones, or phalanges, I - of the two.

As a whole foot bones connected by joints and ligaments that make it a reliable support on the one hand, and on the other (due to the flexibility and mobility) give the foot shock-absorbing properties. Spring when a man walking help vaults or special foot bends, there are six: five longitudinal (each corresponding to one of the five metatarsal bones) and one cross that unites together lengthwise.

Why can arise Jones fracture

Fracture feet - quite common, it occurs when you fall on your feet, with the direct impact of the rear foot, with gunshot wounds and so on. But the most likely to suffer the tarsal bones - heel and containers - they are responsible for the brunt of the fall from a height.

Fractures of short tubular metatarsals usually occur in the direct mechanism of injury: the fall of gravity to the rear of the foot or the sudden rapid hyperextension stops. At the same time there are often multiple fractures, fractures with dislocation combination Dislocation - Prevention and Treatment  Dislocation - Prevention and Treatment
   and open injuries. For isolated fractures of metatarsals large displacement of fragments is not typical at the time, as multiple fractures are often accompanied by significant displacement of bone fragments. Very often, Jones fracture combined with fractures of the phalanges.

How does Jones fracture

Jones fracture is manifested by severe pain at the fracture site. For such fractures characteristic symptom Jacobson: increased pain at the fracture site with pressure on the metatarsal head. Pain increases as when you pull out the corresponding finger. Sometimes the fracture appears abnormal mobility and bone crepitus Crepitus - a very serious symptom  Crepitus - a very serious symptom
   (rattle) - it allows immediately suspected fracture. A little later in the fracture appear swelling and redness.

Diagnosis is based on studying the mechanism of the injury, the characteristic signs and X-ray of the foot in several projections. The X-ray can clearly see the fracture site, the presence or absence of displacement of fragments, which will help to further the proper treatment of the fracture.

Treatment of fracture of metatarsal bone

Fractures of the metatarsal bones without moving the casting of heal from the foot to the knee. At the turn of a metatarsal bone plaster cast is applied for 2-3 weeks, with multiple fractures metatarsal bones - 4-6 weeks. Before casting of fracture spend anesthesia 1-2% solution of novocaine Novocaine - why it is so popular in medicine?  Novocaine - why it is so popular in medicine?
 . Plaster bandages necessarily simulate transverse and longitudinal arches of the foot, enhancing the dressing in the appropriate places.

When fractures offset required closed or open reduction (sharing) of fragments of bone fragments fixation with needles and applying immobilization (immobilization, usually cast). Particular care should be compared with the angular displacement of the fragments, when the angle is open in the back side, and a fractured metatarsal necks. Manual reposition made pressure on the fragments were moved during the stretching of the foot on the axis of the respective finger. Plaster cast is applied to the knee joint.

If you single-step repositioning has failed, or a fracture has a tendency to shift in a cast, conducted for the extension of the soft tissue or skeletal traction. The frame for the extension is attached to the cast, is superimposed on the feet and legs. Traction removed after 3-4 weeks, a plaster cast - 7 weeks. Surgical treatment is carried out in open fractures (broken skin) and failure of closed reduction.

Employability in fractures of the metatarsal bones is reduced for 1, 5-4 months depending on the nature of the damage.

Patella fracture: it is better not to move - Types and symptoms

  • Types and symptoms

Types and causes of fractures of the patella

Fractures of the patella can be opened and closed, the latter are more common. Fractures of the left and right patella occur with equal frequency in both sexes, often in middle and old age. Patella fractures are intra-articular (except fracture of the top).

Fractures of the patella arise from the direct blow to the patella, on a strong and rapid reduction in quadriceps or simultaneous action of these two points. The most frequent transverse fractures (patella fracture line divides into upper and lower parts). There are also fractures of the lower pole of the patella and the edges (marginal fractures). Vertical fractures are rare and sometimes are not diagnosed.

Signs of a fracture of the patella

Violations of the limb in fractures of knee pads depends on the nature of fracture and the degree of damage to his muscles. When patellar fractures without displacement or divergence of fragments less than half a centimeter ligaments are usually not damaged. Large discrepancies fragments patella always points to support gaps (side) ligaments, so while reducing quadriceps patellar fragments shifted a few centimeters. For fractures of the patella in the knee joint always appears blood (hemarthrosis). The volume of the knee increases, active movement in it becomes impossible, the limb is straightened in a position to raise it the patient can not. Fragments of the patella easily palpated.

For fractures without displacement of fragments, patients sometimes go on their own, due to the preservation of joints and ligaments of the knee. After fracture of the patella in the knee joint often develops deforming arthrosis Osteoarthritis - when the joint loses its function  Osteoarthritis - when the joint loses its function

External signs of fracture of the patella have a number harakternyhosobennostey nevertheless to clarify the diagnosis necessarily carried out X-ray examinations. Radiological fracture of the patella is especially visible on the lateral radiograph, but in some cases a shot in direct projection (the leg is straight).

First aid

First aid for fractures of the patella is the immobilization (creating a state of immobility) of the knee joint using special tires or improvised (umbrella, hard bags, plates, etc.) imposed by the upper thigh to the ankle.

Patellar fractures without displacement of fragments or a divergence of less than half a centimeter treated conservatively (without surgery) by a special method of immobilization of the limb for a month. Permission is walking with crutches. Golf removing immobilization bandage appointed physiotherapy, massage and physiotherapy. Employability is recovering at 1, 5-2 months.

Surgical treatment is indicated for fractures of the patella with the divergence of the fragments of more than half a centimeter. This is most often used by Schultze-Berger, in which after the cut soft tissue removed blood clots, pull together fragments on the torn lateral ligament sutured. After that, the soft tissue around the patella stitch threads (one thread from above, the other below), spectacular deep tissue. The period of immobilization after such an operation - about a month, and then prescribe physical therapy and massage. Term of rehabilitation in this type of operation 2-2, 5 months.

There are also other types of operations. Thus, when fractured patella fractures shown its removal, especially for older people. The function of the limb at the same time not significantly disturbed.

Timely recourse when a knee injury can prevent various complications of the knee joint.
