Treatment of posterior malleolus fracture, like any other type of ankle fracture includes conservative (non-surgical) and surgical approach. The possibility of nerve injury and other soft tissue injury must be evaluated to plan appropriate investigations and treatment. This often needs emergency medical assistance. In case of displacement of bones, the treatment of posterior malleolus fracture would require joint reduction, in which the displaced bones are brought to their original position. Icing can be done for pain and swelling resulting from posterior malleolus fracture, but is best avoided if there is a severe injury or if a complicated fracture is associated with dislocation or displacement. Resting the joint and elevating the leg is often advisable for posterior malleolus fracture. The treatment of posterior malleolus fracture, in case of injury to the ankle joint, needs immediate treatment, which includes the following. What is the Immediate Treatment of Posterior Malleolus Fracture? If other soft tissue damage, ligament injuries or other fractures are suspected, additional scans like CT scan and MRI may be needed. (4) X-ray also gives an idea about the type and severity of posterior malleolus fracture. X-ray confirms a break in the bone in this case, it could be posterior and sometimes even medial and lateral malleolus (inner and outer side of the ankle). The diagnosis of posterior malleolus fracture can be confirmed by x-rays and other scanning investigations. In general, if there is pain and tenderness at the medial and lateral malleolus or if the person is unable to walk due to severe ankle pain and swelling, a fracture is suspected and x-ray is advisable. Examination of the ankle joint reveals pain, tenderness and swelling, based on which a possibility of multiple fractures and soft tissue injury can be assessed. (4) The history often reveals an accident, fall or sports injury, as the complaints begin soon following the injury. What is the Diagnosis of Posterior Malleolus Fracture?ĭiagnosis of posterior malleolus fracture and associated injuries can be made based on the history, clinical examination and x-ray. Other symptoms of posterior malleolus fracture include: limited range of movements, pain on moving or turning the ankle and difficulty in standing and walking. Some may also experience ankle stiffness and swelling around the injured area. Pain may worsen and may be present even after low impact activities like walking and eventually even at rest. Another common symptom is the inability to bear weight on the ankle, stand or walk. Symptoms of posterior malleolus fracture caused due to weak ligaments may cause pain along with ligament instability. In severe fractures, the injured or displaced bones may be noticeable. Usually, as it is a part of trimalleolar fracture, the entire ankle is swollen, painful and bruised. Bruising or signs of local injury may be noted. Tenderness is noted in the injured region, which aggravates on applying pressure.įollowing an injury, severe pain and swelling of the area is the commonest symptom of posterior malleolus fracture. (4) Pain is often worse on moving the ankle, turning the ankle inwards or outwards with difficulty in standing or walking. (4) Pain may also be present on the inner and outer malleolus, if the posterior malleolus fracture is associated with fracture of other malleolus as well. Symptoms of posterior malleolus fracture include pain at the posterior side of the ankle. What are the Symptoms of Posterior Malleolus Fracture? Sometimes, repeated injuries to the soft tissues, ligament tear or weakening of the supporting structures in elderly people or those with joint problems too can result in trimalleolar ankle fractures and posterior malleolus fracture. Some of the causes of posterior malleolus fracture also include a direct blow to the ankle or sudden, forceful impact on the ankle, as during vehicular accidents. (7) Falls, tripping over too can cause posterior malleolus fracture and trimalleolar fracture. (7) Rolling that results from irregular or improper placing of the foot or landing on an uneven surface, too can be one of the causes of posterior malleolus fracture. (3) Sports that involve sudden twisting and turning, which can easily injure the ankle are one of the commonest causes of ankle fractures, posterior malleolus fracture and trimalleolar fractures. The causes of posterior malleolus fracture include: twisting the ankle joint, falls, accidents or injuries to the leg including sports injuries. It is often noted that isolated posterior malleolus fractures are rare and they are mostly seen with other ankle injuries. What Causes Posterior Malleolus Fracture?
