Which of the following is the most common complication encountered during limb lengthening with an Ilizarov ring fixator?

• A Refracture of the regenerate
• B Pin tract infection ✓
• C Deep vein thrombosis
• D Delayed union at the docking site

Explanation

Pin tract inflammation and infection affect the majority of patients undergoing ring fixator application and are the most frequently reported complication of the technique. Most cases respond to local pin site care and oral antibiotics; a wire or half-pin is removed and repositioned only when there is radiological loosening or a sequestrum. Refracture, thromboembolism and docking site problems are recognised but occur far less often, making them distractors rather than the answer.
