1. High-Yield Flashcards
Tap each question to reveal the answer.
What are the four overlapping phases of wound healing?
Haemostasis, inflammation, proliferation and remodelling.
What is the main early function of the platelet–fibrin clot?
It controls bleeding and provides a temporary scaffold for repair cells.
Which cell coordinates the transition from inflammation to tissue repair?
The macrophage.
What are the main components of granulation tissue?
New capillaries, proliferating fibroblasts and loose extracellular matrix.
Which cells produce wound contraction?
Myofibroblasts.
Why does a mature scar become pale?
Newly formed capillaries regress during remodelling.
Which findings suggest a relatively fresh wound?
Fresh bleeding, fibrin clot, swelling and early inflammation.
Which findings suggest an older wound?
Macrophages, granulation tissue, fibroblasts, collagen and scar formation.
Why can wound age not be stated as an exact time?
Healing varies with infection, perfusion, nutrition, wound site, treatment and health status.
What does the central histochemical injury zone show?
Maximum tissue destruction with reduced or absent enzyme activity.
What is itlaf-i-udw?
Severance, dismemberment or destruction of an organ or limb.
What is itlaf-i-salahiyyat-i-udw?
Permanent loss or impairment of an organ’s function while the organ may remain present.
How do jaifah and ghayr-jaifah differ?
Jaifah enters a body cavity; ghayr-jaifah does not.
What is the difference between arsh and daman?
Arsh is fixed by law; daman is assessed by the court when no fixed arsh applies.
What is the doctor’s main role in a work-related injury claim?
Document the injury, impairment, functional limitation and expected incapacity.

2. Mnemonics
Mnemonic Title: Phases of Wound Healing HIPR Meaning: Haemostasis → Inflammation → Proliferation → Remodelling.
Mnemonic Title: Shajjah Severity Sequence K M H M A D Meaning: Khafifah → Mudihah → Hashimah → Munaqqilah → Ammah → Damighah.
Mnemonic Title: Compensation and Punishment Terms Q-D-A-D-T Meaning: Qisas = similar retaliation; Diyat = compensation for death; Arsh = fixed compensation for hurt; Daman = court-assessed compensation; Tazir = state or court punishment.

3. Memory Tables
Fresh versus Older Wound
| Feature | Relatively Fresh | Relatively Older |
|---|---|---|
| Surface | Moist blood or recent clot | Dry scab or epithelial covering |
| Cells | Early neutrophils | Macrophages and fibroblasts |
| Repair tissue | Minimal or absent | Granulation tissue and collagen |
| Interpretation | Supports recent injury | Supports healing progression |
Commonly Confused Legal Terms
| Term | Key Meaning | Memory Clue |
|---|---|---|
| Itlaf-i-udw | Anatomical loss or destruction | Organ is lost |
| Itlaf-i-salahiyyat-i-udw | Permanent functional loss | Organ remains, function is lost |
| Arsh | Compensation fixed by law | Amount already prescribed |
| Daman | Compensation assessed by court | No fixed arsh applies |
| Diyat | Compensation linked with death | Death compensation |

4. Rapid Revision Points — Last-Minute Revision
- Macrophages link inflammation with fibroblast activation and angiogenesis.
- Granulation tissue is vascular repair tissue, not a mature scar.
- Collagen deposition increases wound strength, but healed skin does not regain full normal strength.
- Infection, foreign material and poor perfusion delay healing.
- Histochemical findings must be correlated with gross and microscopic examination.
- Shajjah applies to the head or face; jurh applies elsewhere on the body.
- Jaifah enters a body cavity; ghayr-jaifah does not.
- Dangerous to life describes physiological severity, not merely the weapon used.
- Emergency treatment should not be delayed for police formalities.
- Workmen’s compensation requires a connection between employment and injury, disease, disability or death.
Common KMU Trap: A small external wound can still be dangerous to life if it causes major internal bleeding or organ injury.
5. Clinical Memory Hooks
Fresh bleeding with fibrin and early inflammation → Relatively recent wound, but exact dating remains unsafe.
Dry wound with fibroblasts and early collagen → Older healing wound with active repair.
Eye remains present but vision is permanently lost → Itlaf-i-salahiyyat-i-udw.
Workplace injury causes lasting reduction in grip strength → Permanent partial disability assessment.

6. Starred High-Yield Exam Points
- ⭐ Wound healing phases overlap: haemostasis → inflammation → proliferation → remodelling.
- ⭐ Wound age is approximate because local and systemic factors alter healing.
- ⭐ Shajjah-i-mudihah exposes bone; hashimah fractures it; munaqqilah fractures and displaces it.
- ⭐ Ammah reaches the cranial membrane; damighah ruptures it and affects the brain.
- ⭐ The doctor records medical facts; the court decides punishment and compensation.
- ⭐ Injured persons require prompt treatment and stabilization before administrative formalities.
