Sprains hand bones


Sprains occur in the bones of the hand wrist joint. Skeleton hand consists of a large number of small wrist bones and joints and polusustavov between them.

Radiocarpal joint - this is the joints between the ulna and radius bones of the upper side and the eight bones of the hand from the bottom. Eight small, short bones, connecting with each other in two rows to form the wrist. The upper range of their form navicular, lunate, triangular, and pisiform. Had meetings sprains scaphoid and lunate bones. The remaining carpal bones undergo dislocation is extremely rare.

Dislocation of the scaphoid

Dislocation of the navicular bone occurs by direct attack on the brush when it is flexed position and tucking in the direction of the elbow. Scaphoid with tears carpal joint capsule from the back of the hand and she moves into the back side. The patient complains of pain in the wrist. In the place of dislocation of the edema. The brush is changed. Motion in the wrist become painful and limited. When probing brush, you can detect bone protrusion on her rear. Refine the diagnosis of X-ray examination.

Treatment of dislocation of the navicular bone. Place dislocation numbed with conduction anesthesia or general anesthesia is used. If the dislocation has occurred recently, trying to straighten the navicular bone by pulling the first 3 fingers. When returning the bone to its place there is a kind of clicked. After reduction to impose a circular brush plaster cast from the beginning of the metacarpals to elbow for 5-7 weeks. When used long-dislocation surgically reposition of the navicular bone. In any case, after removing the plaster appointed physiotherapy and mechanic.

Dislocation of the lunate bone


Dislocation of the lunate bone develops due to excessive rear extension brush, for example, in the fall, with an emphasis on the palm. Lunate bone of the joint capsule ruptures and shifts toward the palm. At the same time the bone is rotated around its axis sometimes more than 90 degrees. The patient complains of pain in the hand and wrist. In the region of the lunate bone in the back of the hand revealed retraction, and from the palm of detectable bone protrusion. Probing sharply painful. Fingers half-bent patient retains. Trying to extension or contraction of the fingers into a fist wrist causes pain. When the dislocation of lunate bone may be damaged median nerve. Refine the diagnosis of radiographically.

Treatment of dislocation of the lunate bone. Used for anesthesia or nerve block anesthesia. Traction is carried out for the fingers. The surgeon then presses down on the bone and reduce a her. Can be used on hardware reset of dislocation. After that, superimposed circular plaster Longuet first hand in one position, then a week later, the position of the brush and change the cast are still 3 weeks. When stale dislocation or failure of reduction of dislocation of fresh surgical treatment is applied. After removal of the cast is assigned physical therapy and physiotherapy.

Dislocated wrist perilunarny

Perilunarny dislocated wrist is common. At the same lunate bone remains in place are articulated with the radius, and all the other carpal bones below the lunate bone, dislocate in the back of the hand. Options are not all the dislocations of the bones, and several of them. Perilunarny dislocated wrist may be accompanied scaphoid or triangular bone. The patient is worried about the pain in the wrist, swelling. Hand function is disturbed. Flexion and extension wrist and fingers sharply painful.

Treatment of dislocation of the wrist perilunarnogo. Under the conduction anesthesia or general anesthesia produce reduction of dislocation. First, perform stretching the fingers. It is better to carry on a special apparatus. The surgeon then presses down on the dislocated bones of the wrist and reduce a them. When a failed reduction or dislocation of the continued existence of an operational methodology used.


Dislocation of the metacarpal bones

Metacarpal bones - the five short tubular bones between the wrist and fingers. These dislocations occur very rarely, because they are fixed strong ligaments. The mechanism of injury - a strong direct impact on the brush. Almost always sprains metacarpal fractures accompany them.

Treatment of dislocation of the metacarpal bones is in the reduction of dislocation and the imposition of a circular plaster cast of the heads of metacarpal bones to the elbow joint. If necessary, surgical treatment and fixation needles.

Dislocated fingers

Sprains occur in the joints of the fingers between the metacarpal bones and phalanges or principal in the interphalangeal joints. Most often subjected to dislocation of the thumb joints. Injury occurs when excessive straightening, rarely excessive flexion of the finger. The patient complains of pain at the site of injury and edema. The form of a finger to change. Finger movements are impossible and very painful. Refine the diagnosis of X-ray examination.

Treatment of dislocation of a finger brush. Block anesthesia is used. Reduce a finger through his stretching. If the dislocation is accompanied by tears, or denial of the tendons, open reduction is used. Expose the joint cavity, pinching a tendon release, reduce a dislocation.
