Maisonneuve fracture is a type of fracture in the ankle that is caused by a rotational force. This fracture is named after the French surgeon, Jules Germain François Maisonneuve, who first described it in 1840.
Overview
The Maisonneuve fracture is a complex injury that involves a fracture of the proximal third of the fibula (the smaller bone in the lower leg), disruption of the distal tibiofibular syndesmosis (the fibrous connection between the two bones of the lower leg), and a medial malleolar fracture or rupture of the deltoid ligament (the strong, flat, triangular ligament located on the medial (inner) side of the ankle).
Causes
The Maisonneuve fracture is caused by a pronation-external rotation mechanism. This occurs when the foot is planted and the body rotates externally, causing a twisting force on the ankle.
Symptoms
The main symptoms of a Maisonneuve fracture include pain, swelling, and inability to bear weight on the affected leg. There may also be bruising and deformity of the ankle.
Diagnosis
Diagnosis of a Maisonneuve fracture is typically made through a combination of physical examination and imaging studies. X-rays of the ankle and lower leg are usually performed. In some cases, a CT scan or MRI may be needed to further evaluate the injury.
Treatment
Treatment of a Maisonneuve fracture usually involves surgery to repair the broken bones and torn ligaments. This typically involves the use of screws and plates to stabilize the fracture and allow it to heal. Following surgery, a period of immobilization and physical therapy is usually required.
Prognosis
The prognosis for a Maisonneuve fracture is generally good with appropriate treatment. However, complications can occur, including infection, nonunion of the fracture, and post-traumatic arthritis.
