title: Subtalar joint instability: current clinical concepts.
abstract: There has been extensive research and investigation into the subtalar joint (STJ), yet the biomechanics that relate to its anatomic function, especially instability after injury, are surrounded by controversy. With a mechanism of injury closely related to the classic inversion ankle sprain, chronic instability can result following trauma to the lateral ligamentous support network of either joint. Over the past decades there have been countless examples in the literature challenging the current standard of evaluation and treatment of the "subtalar sprain." New technologies have offered varied approaches to diagnostic capability, each with its own strengths and weaknesses, ranging from standard radiographs to CT and MRI. A review of the literature should aid in deciphering the controversy surrounding this aspect of podiatric medicine.
