Lateral malleolus fracture picture9/1/2023 ![]() What are the Treatment Options for Ankle Fractures? In complex cases where detail evaluation of the ligaments is required an MRI scan is recommended. This test is employed to check the stability of the fracture to decide if surgery is necessary or not. In some cases, pressure is applied on the ankle and then special X-rays are taken. Usually it is very difficult to differentiate a broken ankle from other conditions such as a sprain, dislocation, or tendon injury without having an X-ray of the injured ankle. The diagnosis of the ankle injury starts with a physical examination, followed by X-rays and CT scan of the injured area for a detailed view. Syndesmotic injury, also called a high ankle sprain, is usually not a fracture, but can be treated as a fracture.Trimalleolar fractures in which all three lateral, medial, and posterior bones are fractured. ![]() Bimalleolar fractures in which both lateral and medial malleolus bones are fractured.Posterior Malleolus fracture in which the posterior malleolus, the bony hump of the tibia, is fractured. ![]() Medial Malleolus fracture in which the medial malleolus, the inner part of the ankle, is fractured.Lateral Malleolus fracture in which the lateral malleolus, the outer part of the ankle is fractured.The different types of ankle fractures are: What are the Types of Ankle Fractures?Īnkle fractures are classified according to their location. In cases of severe fracture, deformity around the ankle joint is clearly visible where bone may protrude through the skin. In some cases, blood may accumulate around the joint, a condition called hemarthrosis. With an ankle fracture, there is immediate swelling and pain around the ankle as well as impaired mobility. What are the Symptoms of an Ankle Fracture? What are the Common Causes of Ankle Fractures?Īnkle fractures occur from excessive rolling and twisting of the ankle, usually occurring from an accident or activities such as jumping or falling causing sudden stress to the joint. The ankle joint is stabilized by different ligaments and other soft tissues, which may also be injured during an ankle fracture. An ankle fracture is a painful condition where there is a break in one or more bones forming the ankle joint. Pain after ankle injuries can either be from a torn ligament and is called an ankle sprain or from a broken bone which is called an ankle fracture. What is an Ankle Fracture?Īnkle injuries are very common in athletes and in people performing physical work, often resulting in severe pain and impaired mobility. The joint is protected by a fibrous membrane called a joint capsule, and filled with synovial fluid to enable smooth movement. The ends of the fibula and tibia (lower leg bones) form the inner and outer malleolus, which are the bony protrusions of the ankle joint that you can feel and see on either side of the ankle. The ankle joint is composed of three bones: the tibia, fibula, and talus which are articulated together. If an acceptable reduction cannot be obtained using this technique, open reduction and internal fixation should be performed.Ankle Fracture What is Normal Ankle Joint Anatomy? Surgical time is also reduced and tourniquet use is optional. ![]() This closed technique also eliminates screw penetration of the ankle joint and damage to the peroneal tendons, which can be risks when a plate or lag screws are employed as internal fixation. This technique requires minimal soft-tissue dissection, thereby decreasing wound complications and painful hardware sites that are occasionally observed after open techniques. If reduction of the lateral malleolus fracture can be obtained in a closed fashion (with the aid of an image intensifier), we believe that fixation may be performed with an axial screw percutaneously. At latest follow-up, functional results were excellent in 42.1%, good in 42.1%, fair in 5.3%, and poor in 10.5% of patients. There were no deep wound infections or complaints of painful hardware. In all patients the average time to full weight bearing was 6.8 weeks, whereas that in patients with isolated lateral malleolus fractures was 4.5 weeks. Fracture union was achieved in 95.5% of patients, with an average time to union of 8.2 weeks. The reduction that was obtained was maintained in all patients. A good radiographic reduction was obtained in 87.5% of patients, a fair reduction in 8.3%, and a poor reduction in 4.2%. Nineteen of these patients were followed for an average of 63.4 weeks. Twenty-four patients with Weber B and low Weber C displaced lateral malleolus fractures who underwent closed reduction and percutaneous internal fixation with an intramedullary, fully threaded, self-tapping screw were retrospectively reviewed. ![]()
