This CT image displays a cross-section view of the hindfoot and shows a large coalition fusing the talus and calcaneus bones. You can rate this topic again in 12 months. This type of fracture commonly occurs during a high-energy event such as a car crash or a fall from a ladder when the heel is crushed under the weight of the body. [2]Individuals with chronic instability often report recurrent sprains and 'giving-way' sensation at the ankle joint, a condition clinical referred to as Functional Ankle Instability (FAI). (OBQ08.237) This x-ray image of a right foot shows a tarsal coalition between the navicular bone and the calcaneus bone. The lateral side of the ankle has three supporting ligaments: the anterior talofibular ligament (ATFL), the posterior talofibular ligament (PTFL) and the calcaneofibular ligament(CFL). The normal 5th metatarsal apophysis should not be mistaken for a fracture. Tarsal coalitions only require treatment if they are causing symptoms. The word "talus" comes from the Latin word for dice, as Roman soldiers used this bone from horses to make dice for games of chance. Performed over the lower one-third of the posterior calcaneus.

Stable fractures, listed above as type 1 talus fractures, are those in which the bone is still in the proper anatomical position. The cause of injury may be obvious, such as jumping from a height or a heavy object falling and landing on the foot, or it may develop gradually over time, such as the result of the constant stress of walking or Injuries to PTFL usually occur in severe ankle sprains which also involve the ATFL and CFL. Which of the following injuries would require plating of the radius along with closed reduction and evaluation of the distal radioulnar joint (DRUJ)? Fractures of the 5th metatarsal base are a common injury. Depending upon the type and location of your surgery, a cast will be required for a period of time to protect the surgical site and prevent you from putting weight on the foot. An X-ray is Technique guides are not considered high yield topics for orthopaedic standardized exams including ABOS, EBOT and RC. Type 1 talus fractures have a clear vertical fracture line, but very little, if any, separation of the two parts of the talus and it remains in the proper anatomical position within the ankle. coronoid tip.
