tissue bridging)
How to comment cont?.5. Causative instrument: Blunt instrument ( سكينة بالتحديد األلة إسم تذكر ال أو

6. Complications & possible cause of death, e.g:Internal haemorrhageShockInjury to vital organsLoss of a functioning organ
Description of different types of wounds
1. Cut wound: القطعى الجرح Two acute angles Regular edges No tissue bridging Caused by a sharp instrument
2. Lacerated (contused) wound: الرضى أو التهتكى الجرج • Multiple angles• Irregular edges• Tissue bridging • Caused by a blunt instrument
3. Stab wound: الطعنى الجرح• Has two angles1 acute & 1 rounded→single sharp bladed.2 acute angles→double sharp bladed• Regular edges.• It is deeper than longer.• No tissue bridging.
Examples

two parts united at the hilum by a pedicle.It has multiple angles, irregular edges & tissue
bridging.• Causative instrument: blunt trauma• Complications: internal haemorrhage, shock,
loss of a functioning organ.
Ante mortem cut wound
Antemortem cut wound• Specimen: jar• Presenting part: part of lateral aspect of soft
tissue of leg.• Diagnosis: antemortem cut wound• Description of injury: The wound has regular edges, acute angles,
no tissue bridging.Swollen edges, gapping , blood infiltration.• Causative instrument: sharp instrument• Complications: haemorrhage, sepsis
Postmortem cut wound

• Description of injury: The wound has regular edges, acute angles,no tissue
bridging. Less gapping, no swollen edges, no bleeding & no vital
reaction.

Tentative marks
Tentative marks• Specimen: jar• Presenting part: skin of neck• Diagnosis: tentative marks(hesitation marks) in a
case of cut throat.• Description: Multiple parallel superficial cut wounds.With regular edges, 2 acute angles, gapping & no
tissue bridging.• Complications: massive haemorrhage, shock• MLI: tentative marks indicate suicidal manner of
