Case Report Tillaux Fracture in Adult

Case Report Syed et al: Tillaux fracture in adult Tillaux Fracture In Adult: A Case Report Syed T, Storey P, Rocha R, Kocheta A, Singhai S Study performed at Rotherham District General Hospital, Rotherham, South Yorkshire, United Kingdom Abstract Case report We report a rare case of Tillaux fracture of the ankle in a 36-year-old man. He sustained the injury in a football tackle and presented to us with pain and swelling of the left ankle. After preliminary X- rays, a CT scan was done which showed a Tillaux type fracture which is a rare injury after epiphyseal fusion. The ankle was treated with open reduction and internal fixation with screws and plaster for 6 weeks. At 3 months the patient had no pain in the ankle and able to mobilize full weight bearing on that side.

Tillaux fracture is an uncommon, rare ankle injury, described as an avulsion fracture of Case report anterolateral part of distal tibia due to the stronger pull of the anterior tibiofibular A 36-year-old gentleman presented to the ligament, by an external rotation force to the emergency department immediately after foot causing a Salter Harris type III injury [1- trauma sustained in a football tackle. His body 3]. It is typically seen in adolescents who rotated internally when the foot was on have open epiphysis because the anterior ground, when he was hit by an opponent, tibiofibular ligament is stronger than the giving external rotational force injury to the epiphyseal bone, and so the strong pull of this ankle. He complained of excruciating pain and anterior tibiofibular ligament, predisposes to severe swelling on the anterolateral aspect of an epiphyseal bony injury rather than a distal tibia and ankle. He had superficial ligament rupture leading to an avulsion abrasions over the shin. No other injuries were physeal injury to anterolateral distal tibia identified. Distal neurovascular structures [2,3]. Occurrence of this rare tillaux fracture were normal. He had no significant previous in adults is further rare, because in adults i.e. medical history. after physeal fusion, ligament strength is less Plain radiographs of ankle showed a distal than bony strength and therefore a rupture of tibial avulsion fracture of the anterolateral the ligament is more likely than a bony aspect indicating a Tillaux-type injury. He was avulsion [4]. Only very few cases of this given analgesics and placed in a below knee Tillaux fracture in adults has been reported [4- plaster of paris back slab. He was admitted to 9]. In the present report, we describe such the ward and limb was elevated.

He and fibula and is stabilised with four ligaments described it as an external rotation of ankle - the anterior and posterior tibiofibular that leads to an avulsion fracture of the ligaments, transverse tibiofibular ligament and anterolateral aspect of the tibial plafond owing interosseous membrane [1]. to the pull of a taut antero-inferior tibiofibular ligament [11]. Chaput later described similar Sir Astley Cooper, was first to recognize the counterpart injury to the posterolateral tibia Tillaux fracture in 1822, as an avulsion injury (avulsion of posterior tibio-fibular ligament), to antero-lateral distal tibial epiphysis [10]. later called Tillaux-Chaput injury. Tillaux fracture is an eponym given by Paul Orthopaedic Journal of M P Chapter. 2020. Vol. 26. Issue 2 96 Case Report Syed et al: Tillaux fracture in adult Distal tibial epiphysis appears at age 6-10 ankle especially in the anterior part of the months and it unites with the diaphysis at ankle, after a low energy trauma, whereas in about age 18 years [1]. Kleiger and Mankin adults it is usually a high energy trauma and showed that fusion in the distal tibial epiphysis may be associates with other fractures [4-9]. occurs first in the middle third of the epiphysis, followed by, the medial side, and Antero-posterior, lateral and oblique plain finally in the lateral portion [12]. Tillaux radiographs of the ankle are helpful in fracture occurs after the medial part of the diagnosing this fracture. But un-displaced physis has fused but before the lateral part fracture or cursory examination of the closes, hence this injury is commoner in radiographs can miss the injury, necessitating adolescents. computed tomography as a useful adjunct to confirm the diagnosis, clearly define the In adolescents, the lateral physis is open and extent of the fracture, rule out any associated anterior tibiofibular ligament is stronger than injuries involving the tibial pilon and to plan the epiphyseal bone (growth plate). When a management [13,14]. strong external rotational force acts on ankle, it causes a pull force on this strong taut Acute management includes elevation, ice anterior tibiofibular ligament which rather than fomentation and rest. Un-displaced fractures causing pure ligament rupture, predisposes to can be managed non-operatively by below an avulsion epiphyseal bony injury leading to knee non-weight bearing cast immobilisation an avulsion physeal injury to anterolateral for six weeks. Since these are intra-articular distal tibia. Further since the lateral physis fractures and usually displaced due to avulsion growth plate is avulsed away with fracture line pull by the ligament, these injuries need involving the joint, this Tillaux fracture is closed or open reduction with internal fixation typically a Salter Harris type III physeal injury to restore ankle joint congruity aiming [2-4]. In adults this type of injury is very rare congruous reduction, rigid fixation, and early because physeal fusion has already been mobilization for better functional outcome and obtained and the ligament strength is less to prevent complications like nonunion, than the bony strength and ligament will malunion, arthritis, deformity and avascular usually give way and rupture before avulsion necrosis of the fracture fragment [6,7]. of its attachment to the anterolateral tibial plafond, leading to relative rarity of this This open reduction can be done by anterior or avulsion fracture injury pattern in adults. the anterolateral approach [6]. As per Kumar et al anterolateral approach provides the best In adult type of tillaux fracture, the avulsed access to the fracture [9], but we used fracture fragment is triangular as compared to anterior approach for fixation and reduction, the juvenile one, where the fragment is because we suppose the approach should quadrangular. Adult pattern of Tillaux depend on the extend of the fracture line. fractures are classified into Type A and Type Since we have done CT scan, which showed B. Type A is avulsion fracture of the antero- the exact extend of the fracture line, we used lateral aspect of the distal tibial plafond and the anterior approach for fixation. Careful use Type B is a fracture pattern extending into the of wires as “joysticks” to achieve accurate medial aspect resulting in antero medial reduction and fixation, with 1 or 2 inter- pattern [6,7].
