Incised wounds

Incised wounds


Incised wounds

  • Its produced by sharp cutting instruments-knife,razor,blade,swords,chopper,axe etc.
  • Secondary healing occurs in an incisional wound with infection.

Features:

  • Edges are regular,clear cut, retracted and averted.
  • Except in neck and scrotum-edges are inverted.
  • Spindle shaped wound,maximum widening in the central part.
  • Length is greater than the breadth.
  • Breadth is greater than the thickness of the cutting blade.
  • Gaping is greater if underlying muscles are divided across or cut obliquely.
  • Haemorrhage is excessive due to the cleat division of blood vessels.
  • Half severed artery bleeds more as they can neither retract nor contract.
  • Edges of wound may be irregular when skin is loose and if cutting edge is blunt.
  • By nature of the incised wound,weapon used can be identified.
  • Light sharp cutting weapons-razor blades,knife an produce incised wounds by striking,drawing or by sawing.
  • Drawing cuts-Deeper at start,gradually become shallow and at the end only skin is cut with scratch “Tailing of the wound”
  • The position of the accused and victim can be identified in homicidal cases,and suicidal cases which hand has been used.
  • Sawing cuts-Multiple at the beginning and only one deep cut wound called “Tentative or Hesitation cuts”
  • Bevelling cuts-When weapon is used oblique or tangential way over the body.

              Medico-Legal importance

Homicidal

  • Any part of the body, commonly on the neck, head and trunk, also be found on the inner side of forearm or hand of victim while defending or protecting. ‘Defence Wounds’. 
  • Slash cuts/chop wound
  • Incised wound on nose, ear and genital are usually homicidal

Suicidal

  • Found in the accessible parts by light weapons on the throat (cut throat wounds). Tail end of the wound indicates which hand has been used.
  • Drawn cuts

 Accidental

  • Any part of the body hands, fingers during the handling of knife, razor blades etc.  

Weapon

  • Incised wound means use of sharp cutting weapons.
  • Bevelled cuts and chop wounds suggest use of heavy or moderately heavy sharp cutting weapons. 

Manner of use of weapon

  • Deep chop wounds and bevelling suggests striking by the weapon.
  • Tailing and hesitation cuts indicate drawing of the weapon.
  • Multiple superimposed or overlapping injuries are indicated by saw like movement of the weapon.

Direction of application of force

  • From the tailing and bevelling, the direction of application of force can be known.
  • The relative position of the victim and the assailant can also be known, by the direction of application of force. 
Aging of Wound
  • When fresh- Bleeding is still present or fresh soft clot is adhered, margins are red, swollen and tender.
  • By 12 hrs- Blood clot and lymph dry up, margins are red and swollen. Histologically there is infiltration of leucocytes. 
  • By 24 hrs- Proliferation of connective tissue cells and vascular endothelium for neo-vascularisation. 
  • By 36 hrs- Fibroblastic infiltration and capillary network formation starts.
  • By 48hrs- Capillary network is completed. Fibroblasts run across the new vessels. 
  • By 3-5days- Vessels are obliterated and thickened, wound heals and scar formation starts and advances.
  • By 6th day- Scar formation is completed. Scab over the wound falls off. After weeks and months, soft, tender, reddish scar becomes tenderless, whitish and firm. 

 Defence wounds

  • Defence wounds result from the immediate and instinctive reaction of the victim to save himself, either by raising the arm to prevent the attack or by grasping the weapon.
  • If the weapon is blunt, bruises and abrasions produced on the forearms or backs of the hand.
  • If the weapon is sharp the injuries will depend upon the type of attack, whether stabbing or slashing.
  • If the weapon is single edged and grasped-single wound. Double edged-double wound.
