  1. Wounds“jars” By Dr / MarwaMagdy Demonstrator of forensic medicine & toxicology

  2. Objectives: • How to comment on jars? • Description of different types of wounds. • Examples : spleen, heart, liver, kidney,…

  3. How to comment? • Specimen: jar • Presenting part:spleen, liver, heart, …. • Diagnosis: lacerated wound, stab wound, cut wound,… 4. Description of injury: • Number • Site • Details of each type of wound( angles, edges, tissue bridging)

  4. How to comment cont.? 5. Causative instrument: • Blunt instrument لا تذكر إسم الألة بالتحديد(سكينة أو • Sharp instrument شومة ) 6. Complications & possible cause of death, e.g: • Internal haemorrhage • Shock • Injury to vital organs • Loss of a functioning organ

  5. Description of different types of wounds • Cut wound: الجرح القطعى • Two acute angles • Regular edges • No tissue bridging • Caused by a sharp instrument 2. Lacerated (contused) wound:الجرج التهتكى أو الرضى • Multiple angles • Irregular edges • Tissue bridging • Caused by a blunt instrument

  6. 3.Stab wound:الجرح الطعنى • Has two angles • 1 acute & 1 rounded→single sharp bladed. • 2 acute angles→double sharp bladed • Regular edges. • It is deeper than longer. • No tissue bridging.
