Simultaneous traumatic dislocation of the hip knee and ankle joints in an ipsilateral limb, does it happen? A case report

Simultaneous dislocation of three joints the hip knee and ankle joint in an ipsilateral limb is a very rare pattern of injury and only a single case has been reported in the literature, but it is associated with acetabulum fracture. A 34-year-old male had met with a road traffic accident involving left lower limb. Radiographic examination revealed (i) Posterior dislocation of the hip joint without any fracture (ii) Posterior dislocation of the knee joint(iii)Open fracture dislocation of the ankle joint with medial malleolus fracture tibial pilon fracture. The patient underwent an immediate closed reduction of the hip joint by Allis method. Simultaneous reduction of the knee and ankle joint was done and appropriate splintage gave. Open wounds were well debrided and trans-articular fixator was placed over knee and ankle joint. At a second stage, the medial malleolus fracture and tibia pilon fracture were fixed. MRI scan was done which revealed an anterior cruciate ligament injury of the knee. At 6-month follow-up, the patient was ambulating with full weight-bearing on both lower extremities without any assistive devices. There always lies a high risk of hemodynamic instability and other serious and life-threatening injuries due to the high velocity of trauma involved in such cases. The outcome of ipsilateral hip knee and ankle dislocation can vary widely depending on the circumstances and other associated injuries.
