Talus fracture usually occur with high energy traumas like falling from height, motor vehicle accidents, skiing injuries. Talus is a foot bone which forms ankle joint with distal tibia and fibula. While it articulates with distal tibia and fibula superiorly, it also articulates with calcaneus inferiorly.
What are the symptoms of Talar Fractures?
Ankle swelling, and severe pain along with difficulty in weight bearing on effected site are the common complaints. Talar fractures are classified as head, body or collum fractures according to the fracture location.
Which problems can a talar fracture lead?
Avascular necrosis of talus in an ominous complication which can be seen following talar fractures. Avascular necrosis is seen secondary to disruption of the blood supply of talus and shows destruction and deformity in the involved talar bone.
Degenerative osteoarthritis is another complication that can be seen in either talonavicular, or tibiotalar or talocalcaneal joints.
Nonunion of talar fracture and chronic ankle pain are the other major complications encountered following talar fractures.
How to assess the talar fractures?
In most cases, diagnosis is made by physical exam and direct radiology.However, it is very important to identify the fracture exact location and pattern so that appropriate treatment could be commenced.
Treatment of Talar Fracture
Possible complications like avascular necrosis, osteoarthritis, and pain can be prevented with anatomic reduction and stable internal fixation. For that reason, most talar fractures are treated surgically. Talar fracturs which are classified as nondisplaced incomplete fractures, bone fissurs, fractures without any risk of displacement can be treated with nonsurgical techniques like cast application. Most patients treated with cast are not allowed put pressure on the fractured foot for 6-8 weeks.
