A2 - Rahul G., Patwari PY - 2014 T2 - Clinical Emergency Medicine AB - If a hip fracture is suspected in an elderly patient, but plain radiographs are negative, obtain a computed tomography scan or magnetic resonance imaging.Delay in the reduction of a hip dislocation increases the likelihood of avascular necrosis of the femoral head.The presence of normal distal pulses after a knee dislocation does not exclude popliteal artery injury.A fracture at the base of the second metatarsal should raise suspicion for a Lisfranc fracture-dislocation.
