Traumatic ablation - a casting-off of a part or all extremity (or other part of a body) as a result of mechanical violence. A specific variant of the mechanism of traumatic ablation is the abruption of an extremity. Distinguish full and incomplete traumatic ablation. At last the part of an extremity remains bound with a stump a flap of a skin, muscles or tendons. Traumatic ablation arises more often as a result of a so-called rail trauma, crossing by a wheel of a train or a tram. Other reasons can be a tightening of an extremity in moving parts of mechanisms, falling on it of the big load. Ablations are frequent at explosive wounds of a wartime. The skin and a bone are refractoriest to a trauma. Therefore muscles, vessels and nerves happen are crushed in the remained part of an extremity on a greater extent, than it is possible to judge it by the form a dermal wound.

Extensive destructions of soft tissues and bones of a stump are characteristic for action of the big gravity (the syndrome of a long prelum or a syndrome of a compression failure in this case can join), and also for a rail trauma. For an abruption the unit of elements of a segment at different levels is characteristic: so, stumps of nerves, vessels can settle down much more proximally a wound. The hyperinflate or crushed main vessels of a stump, as a rule, are thrombosed, bleed only muscular branches and vessels of a bone. The wound of a stump, as a rule, is strongly polluted. Complications. The most frequent and dangerous complication - a traumatic shock. It the more hardly, than more proximally a level of traumatic ablation. The most serious, often irreversible shock arises at ablation of both femurs. Gravity of a shock influence also frequent (at 80 % of victims with traumatic ablation) other traumas of extremities and internal organs. Damage of the last can dominate over a clinical picture and define the forecast. Other general complications (an acute renal failure, a fatty embolism, a thromboembolism) are closely bound to gravity of a shock, full value of its treatment and with gravity of a trauma. Is purulent-septic complications are most frequent: purulent necrotic process in a wound of a stump, an osteomyelitis, less often a sepsis, a mephitic gangrene in a cult, a tetanus.
