What is talocalcaneal fibrous coalition?
Introduction. The talocalcaneal coalition is a frequent cause of painful flatfoot in older children or adolescents. The talocalcaneal coalition is an anomalous connection between the talus and the calcaneus. The talocalcaneal coalition can be fibrous (syndesmosis), cartilaginous (synchondrosis), or bony (synostosis).
What does a tarsal coalition look like?
Symptoms of tarsal coalition can include: Pain and stiffness in the foot and ankle, particularly when your child is walking or standing. A rigid flat foot, which may make walking more difficult. Walking with a limp. Muscle spasms in the leg, which can cause the foot to turn inward.
What is fibrous tarsal coalition?
Description. A tarsal coalition occurs when two bones grow into one another, connected by a bridge of bone, cartilage, or strong, fibrous tissue. These bridges are often referred to as “bars” and they can cover just a small amount of the joint space between the bones, or a large portion of the space.
How is talocalcaneal coalition treated?
Conclusions: A symptomatic talocalcaneal coalition can be treated with excision and fat graft interposition, and achieve good to excellent results in 85% of patients. Patients should be counseled that a subset may require further surgery to correct malalignment.
How common is talocalcaneal coalition?
Calcaneonavicular coalition was found to be the most common type (53%), followed by talocalcaneal coalition (37%). The other types appear infrequently. Most calcaneonavicular and talocalcaneal coalitions present as a painful foot of some type.
What causes a talocalcaneal coalition?
Causes. Most often, tarsal coalition occurs during fetal development, resulting in the individual bones not forming properly. Less common causes of tarsal coalition include infection, arthritis or a previous injury to the area.
Does tarsal coalition need surgery?
Tarsal coalition can be treated with surgical or nonsurgical methods, depending on the severity of the condition.
What causes a Talocalcaneal coalition?
What is the talocalcaneal coalition?
The Talocalcaneal coalition is the second most common tarsal coalition in the foot after the calcaneonavicular coalition. Tarsal coalitions cause gradual flattening of the medial longitudinal arch resulting in a flat foot and stiffness of the subtalar joint. [1]
Can you have more than one tarsal coalition in your foot?
In some cases, more than one type of tarsal coalition may be present in the same foot. Calcaneonavicular coalition (or calcaneonavicular bar): This form of tarsal coalition involves the calcaneus bone (the heel bone) and the navicular bone (located at the top of the midfoot).
What are calcaneonavicular coalition and congenital vertical talus?
Calcaneonavicular coalition – identified by lateral pain in the foot and an anteater sign on the radiographs Congenital vertical talus – rocker-bottom foot associated with a vertical talus on the radiographs, which does not correct on dorsiflexion of the foot
What bones are affected by tarsal coalition?
Tarsal coalition affects the bones in the midfoot and heel, which are called the tarsal bones. There are several different forms of tarsal coalition. Any of the seven tarsal bones could be affected, but the calcaneus, navicular, and talus bones are the ones most commonly involved.
