Damage To The Nerves OF The Upper And Lower Limbs

Damage to the nerves of the upper and lower extremities, unfortunately, is one of the most frequent and serious types of injuries that can radically change the quality of the image of a person’s life, in everyday household and in a professional environment. A considerable number of diagnostic errors tactical and technical nature in everyday clinical medical practice, unfortunately, result in the complete or partial disablement of the patient is often forced to change the profession of patients, become a cause of disability.

Causes Damage To The Peripheral Nerves

Damage to the peripheral nerves are divided into indoor and outdoor.

Closed Injuries:  as a result of compression of the soft tissues of the hands or feet, e.g., due to improper use of a tourniquet during bleeding, as a result of injury or a strong impact, the long limb position stimulated with pressure from the outside, as a consequence of bone fractures. As a rule, the full interruption of the nerve in such cases is not observed, so the outcome is usually favorable. In some cases, such as sprains hand bones, dislocation of the foot or a major joint, closed fractures of the extremities with displacement of bone fragments may be complete break nerve trunk or even a few nerves.

Open injuries are the result of broken glass wounds, knife, sheet metal, machine tools, and so on. N. In this case, damage to the nerve structure integrity always occurs.

Unfortunately, often nerve damage are the consequence of surgeries.

Upcoming changes occur depending on the level of the nerve damage, injury or character duration of exposure traumatic agent different syndromes function disorders.

Clinical Picture

When closed injuries in case of an injury (contusion) or shake nerve changes nerve trunk of the internal structure does not occur, and sensory disturbances of function of a temporary, transient and usually completely reversible. Dysfunctions of a bruise have a deep and long-lasting in nature, but after 1-2 months are marked with their full recovery. However, ignore the consequences of such injuries cannot be self-diagnosis and treatment are unacceptable, because the consequences of the “self” may be irreversible. The need for immediate access to a doctor traumatologist, surgeon, neurologist. The doctor, if necessary, may appoint additional research to clarify the extent of nerve damage – electromyography, ultrasound -Studies along the nerve trunk, sometimes CT and MRI studies. Only a qualified doctor will prescribe you an adequate treatment.

Open injuries of peripheral nerves. All peripheral nerve fibers mixed type – motor, sensory and autonomic fibers, quantitative relationships between these types of fibers vary in different nerves, so in some cases more severe motor impairment, in other there is a decrease or complete lack of sensitivity in the third – vegetative disorders.

Movement disorders are characterized by paralysis or individual muscle groups, accompanied by the disappearance of the reflections and eventually (1-2 weeks after injury) atrophy of paralyzed muscles.

Sensory disturbances occur – reducing, pain disappearance, temperature, tactile sensitivity. Pain, worse in a delayed manner.

Autonomic symptoms – in the first period after skin injury red hot and a few weeks later becomes cyanotic and cold (vasomotor disturbances), the appearance of edema, disorders sweating, trophic skin disorders – dryness, flaking, sometimes even ulceration, nail deformity.

On The Upper Limb

In case of injury the top (third) of the shoulder and upper third of the forearm most often affects the radial nerve – brush hangs, its extension and the main phalanges impossible, fingers hanging jelly, possible abduction of the thumb .. Sensory disorders are less pronounced – loss reduction zone or the rear surface of the shoulder and forearm sensitivity and dorsum of the hand 2 fingers without end phalanges. Swelling of the hands.

When the median nerve is damaged large bending offline (I), the index (II) and secondary part (III) of fingers, brushes turns impossible opposition and abduction of the thumb, which is coplanar with the rest of the fingers. Reduced sensitivity of all kinds on the hand (finger 3) and the end phalanges II, III, IV (unnamed) fingers on the back side of the palm. Characterized by pain and marked autonomic manifestations.

Ulnar nerve trauma leads to disruption of flexion IV, V (little finger) finger actuation and withdrawal of the fingers; V, IV, III fingers partly unfolded in the core and bent at the middle phalanx. Expressed atrophy intercostals muscles. Sensitivity upset on the ulnar half brush, V and IV half finger.

When axillary nerve injury of shoulder abduction is impossible, there is atrophy of the deltoid muscle, impaired sensitivity to topically-back of the shoulder. The defeat of the musculo-cutaneous nerve excludes the possibility of simultaneous extension and forearm supination brush.

On Lower Limb

With the defeat of the common trunk of the sciatic nerve in the upper half of the thigh are lost flexion and extension of the foot and toes. Stop hangs, you can not stand on his toes and heels. Sensory disorders are on the foot and the back of the leg. Typical autonomic disturbances, trophic ulcers of the foot. Tibial nerve damage leads to the disappearance of foot flexion and fingers. Straighten stop fingers are in claw position. The sensitivity is upset on the rear surface of the tibia and nenaruzhnoy, sole and the outer edge of the foot. Pronounced vegetative disorders – pain. The lack of sensitivity available on anteroinferior surface of the tibia.

Here is a summary of violations arising from the injuries of peripheral nerves of the upper limb. Full clinical diagnostics nerve damage, of course, more complicated, and the doctor performed using additional methods of research. Some of the medicines are being used widely in all over the world.
