Association of Bosworth, Pilon, and Open Talus Fractures: A Very Unusual Ankle Trauma

الملخص EN

Introduction.

A Bosworth fracture-dislocation is a rare lesion resulting in a fixed dislocation of the distal fibula behind the posterior tibial tubercle.

Only few cases have been reported showing an associated consequent fracture, namely, a pilon or a medial malleolus fracture.

Case Report.

We present a case report of a patient with an unusual combination of a Bosworth injury with a pilon fracture and an open multifragmentary talus fracture and our approach for open reduction and internal fixation.

At one year postoperative, the patient developed an invalidating tibiotalar and subtalar arthrosis that eventually required an ankle-hindfoot arthrodesis.

A Bosworth injury is an infrequent entity and is even rarer when associated with other fractures.

Careful preoperative planning is necessary, as the combination of these fractures is a surgical challenge.

Special care must be taken to preserve the neurovascular bundle.

Discussion.

The present case highlights a Bosworth injury involving a severity that has never been described before and suggests adding an eighth stage to the classification presented by Perry et al.
