Subtalar arthroereisis has advantages over other foot pain treatments for primary and secondary flatfoot, as well as for stabilizing the subtalar joint into its correct alignment. While this procedure offers certain benefits, it is not without its drawbacks.
The subtalar joint is particularly susceptible to arthritis, especially when it has previously been affected by sprains or fractures such as those of the calcaneum or talus. Symptoms of subtalar joint arthritis include pain when walking, loss of motion through the joint's range of motion, and difficulty walking on uneven surfaces.
The ankle is composed of three joints: the talocrural joint (also called talotibial joint, tibiotalar joint, talar mortise, talar joint), the subtalar joint (also called talocalcaneal), and the Inferior tibiofibular joint. [3] [4] [5] The joint surface of all bones in the ankle is covered with articular cartilage.
If not recognized and managed appropriately, a talus fracture may result in complications and long-term morbidity. A 2015 review came to the conclusion that isolated talar body fractures may be more common than previously thought. [4] A fractured talar body often has a displacement that is best visualised using CT imaging. In case a talus ...
Sinus tarsi syndrome can have a variety of causes. The most common is an inversion (rolling out) ankle sprain, which makes up 70-80% of cases, followed by pronation of the foot, which is responsible for about 20-30% of cases. [3]
A subtalar dislocation, or talocalcaneonavicular dislocation, is a simultaneous dislocation of the talar joints at the talocalcaneal and talonavicular levels. [47] [48] Subtalar dislocations without associated fractures represent about 1% of all traumatic injuries of the foot. They represent 1-2% of all dislocations and are caused by high ...
Intra-articular fractures are more common and involve the posterior talar articular facet of the calcaneus. The Sanders classification groups these fractures into four types based on the location of the fracture at the posterior articular surface. Extra-articular fractures are less common and may be located anywhere outside the subtalar joint. [13]
It is part of the lateral collateral ligament, which opposes the hyperinversion of the subtalar joint, as in a common type of ankle sprain. [ 1 ] It is covered by the tendons of the fibularis longus and brevis muscles.
