مريض عمره ٨٥ سنة طريح الفراش منذ شهر بعد كسر الورك، عنده مفصل ركبة لا يتمدد كاملاً، والكاحل مائل للأسفل. لم يكن يُحرك بانتظام. ما المضاعفة وما الوقاية؟

An 85-year-old bedbound for a month after hip fracture has a knee that will not fully extend and a plantar-flexed ankle. He was not moved regularly. What is the complication and prevention?

1. Thrombosis; prevented by massage
2. A new fracture; prevented by a cast
3. Contractures; range-of-motion exercise
4. Normal wear; it cannot be prevented

Answer: C) Contractures; range-of-motion exercise. Immobility causes contractures and foot drop, prevented by range-of-motion exercise, correct positioning, foot splints and early mobilisation.
