An Unusual Presentation of Chaput Tubercle Fracture with Coexisting Bimalleolar Component Involving Lateral and Posterior Malleoli: A Case Report
Chaput Fracture
Abstract
Chaput tubercle fracture is a counterpart to adolescent tillaux fracture, which occurs at the anterolateral part or at the attachment site of the antero-inferior tibiofibular ligament on the distal tibia. It is rare and its presentation may not be well appreciated in X RAYS which depicts the importance of a CT scan of ankle to reveal the same. A 25-year-old gentleman presented to us in the casualty with acute onset of pain, swelling and restricted movements at the ankle joint following a road traffic accident. CT Ankle revealed a chaput fracture along with bimalleolar fracture (posterior and lateral malleoli). The complex displaced fracture was managed with open reduction internal fixation with plate osteosynthesis for the posterior malleoli and lateral malleoli, tension band wiring was done for the chaput tubercle fracture. At the end of 2 years follow up, Patient was able to mobilise without any support. Through this case report, we would like to enumerate the rarity of chaput tubercle fracture associated with bimalleolar fracture of ankle which will be evaluated better with a CT evaluation at the first place. At the same time, it gives valuable information for the preoperative surgical plan.
