Acute Compartment Syndrome of the Foot Following Fixation of a Pilon Variant Ankle Fracture

Acute traumatic compartment syndrome of the foot is a serious potential complication after fractures, crush injuries, or reperfusion injury after vascular repair. Foot compartment syndrome in association with injuries to the ankle is rare. This article presents a case of acute compartment syndrome of the foot following open reduction and internal fixation of an ankle fracture. A 16-year-old girl presented after sustaining a left ankle injury. Radiographs demonstrated a length-stable posterior and lateral malleolar ankle fracture. Initial treatment consisted of a bulky splint and crutches pending the improvement of her swelling. Over the course of a week, the soft tissue environment of the distal lower extremity improved, and the patient underwent open reduction and internal fixation of both her fibula and distal tibia through 2 approaches. Approximately 2 hours from the completion of surgery, the patient reported worsening pain over the medial aspect of her foot and into her calcaneus. Physical examination of the foot demonstrated a swollen and tense abductor hallicus and heel pad. Posterior tibial and dorsalis pedis pulses were palpable and her sensation was intact throughout her foot.
