Abstract
Chaput tubercle fracture occurs at the antero-lateral position of the distal tibia in adult as a counterpart of adolescent Tillaux fracture. It is a case of adult male which presented to us with onset of acute pain, swelling and restricted movements of ankle after a road side accident. A clinical diagnosis of Chaput tubercle fracture was established after a CT-scan. The displaced fracture was managed by open reduction and internal fixation by screw. At the end of follow up, the foot and ankle ability score measured. Through this case report we convey that Chaput tubercle fracture in an adult is a rare entity.
