uraizy Traumatology The science which deals with all aspects of mechanical injuries Forensic traumatology deals with interpretation and certification of trauma in the light of law uraizy Traumatology Mechanism of wound production Injury is produced when sufficient energy is absorbed so that there is permanent alteration of some part of body’s anatomic integrity. The result is a wound uraizy Traumatology Mechanism of wound production Energy available = V2 M 2g = KE Energy transferred depends upon area of application = A time of transfer = t Energy absorbed - lever action plasticity/elasticity of tissue k inertia hydrostatics uraizy Traumatology Mathematics of wound production Wound = W = uraizy KE x 1 x 1 x k A t Traumatology Sec 332 PPC - Hurt Legal aspects of trauma (1) Whoever causes pain, harm, disease, infirmity or injury to any person or impairs, disables or dismembers any organ of the body or part thereof of any person without causing his death, is said to cause hurt. (2) The following are the kinds of hurt:(a) Itlaf-i-udw (b) Itlaf-i-salahiyyat-i-udw (c) Shajjah (d) Jurh; and (e) all kinds of other hurt. uraizy Traumatology Sec 337 PPC Shajjah Legal aspects of trauma (1) Whoever causes, on the head or face of any person, any hurt which does not amount to itlaf-i-udw or itlaf-i-salahiyyati-udw, is said to cause shajjah. uraizy (2) The following are the kinds of shajjah, namely:(a) shajjah-i-khafifa – (without exposure of bone) (b) shajjah-i-maudiha - (exposure without fracture) (c) shajjah-i-hashimah - (fracture without dislocation) (d) shajjah-i-munaqqilah - (fracture with dislocation) (e) shajjah-i-ammah - (exposure of meninges) (f) shajjah-i-damighah - (rupture of meninges). Traumatology Sec 337-B PPC - Jurh Legal aspects of trauma (1) Whoever causes on any part of the body of a person, other than the head or face, a hurt, which leaves a mark of the wound, whether temporary or permanent, is said to cause Jurh. (2) Jurh is of two kinds, namely:(a) Jaifah i.e. where injury extends to body cavities of the trunk; and (b) Ghair-Jaifah i.e. an injury which does not amount to Jaifah. uraizy Traumatology Sec 337-E PPC Legal aspects of trauma uraizy (2) The following are the kinds of GhairJaifah:(a) Damiyah - rupturing of skin with bleeding; (b) Badiah - cutting or incising the flesh without exposing the bone; (c) Mutalahimah - lacerating the flesh; (d) Mudihah - exposure of the bone; (e) Hashimah - fracturing of a bone without dislocation; and (f) Munaqqilah - fracturing and dislocation of bone.
