Ahmed, 22 years old, presents with a gunshot injury to his right lower limb from an exploding sniper bullet from a distance of about 200m. He has an open wound with a displaced, comminuted, medial shaft tibia and fibular fracture and there was no information about possible nerve or vascular injury. Ahmed came to the emergency department with temporary immobilisation and primary wound care was administered. The initial medical plan was to maintain immobilisation until surgical wound debridement and application of external fixator is possible. | |||
=== Social History === | |||
Ahmed is married and a father of three children; his wife is currently seven months pregnant. He arrived at the hospital unaccompanied by any family member or friends. Ahmed lost his job as a first-aid provider four months ago and has now been given the opportunity to start a part-time job as a health assistant in two weeks’ time. He lives with his family and parents-in-law, both older and partially dependent on him. He lives in a fourth-floor flat of a roughly finished building (shared shower on the ground floor, plastic sheets on the windows, no stairs, and handrail). Ahmed regularly helps his brother-in-law to cultivate a small piece of earth, where the family grows vegetables to support their difficult economic situation. | |||
