The ICD-10 Procedure Coding System (ICD-10-PCS) is a US system of medical classification used for procedural coding.The Centers for Medicare and Medicaid Services, the agency responsible for maintaining the inpatient procedure code set in the U.S., contracted with 3M Health Information Systems in 1995 to design and then develop a procedure classification system to replace Volume 3 of ICD-9-CM.
The posterior talofibular ligament runs horizontally between the neck of the talus and the medial side of lateral malleolus calcaneofibular ligament; The calcaneofibular ligament is attached on the posteromedial side of lateral malleolus and descends posteroinferiorly below to a lateral side of the calcaneus.
The lateral talocalcaneal ligament (external calcaneo-astragaloid ligament) is a ligament in the ankle. It is a short, strong fasciculus , passing from the lateral surface of the talus , immediately beneath its fibular facet to the lateral surface of the calcaneus .
The Broström operation (or Broström-Gould technique) is a repair of ligaments on lateral ankle. It is designed to address ankle instability. More importantly, it is primarily used to repair the anterior talofibular ligament (ATFL) in the ankle. It is thought that the majority of patients regain most function in their ankles.
The three aforementioned parts of bone articulate with the talus bone of the foot. Strictly speaking, there are only two malleoli (medial and lateral), but the term trimalleolar is used nevertheless and as such is a misnomer. The trimalleolar fracture is also known as cotton fracture.
In terms of fracture type, isolated malleolar fractures are most common (two-thirds of fractures); bimalleolar fractures occur in roughly 25% of patients while trimalleolar fractures occur in 5-10%. [10] Open fractures are rare, compromising 2% of all ankle fractures. [21] In children, ankle fractures occur in about 1 per 1000 per year. [3]
One with a broken talus may not be able to walk for many months without crutches and will further wear a walking cast or boot of some kind after that. Talus injuries may be difficult to recognize, [9] [10] and lateral process fractures in particular may be radiographically occult. If not recognized and managed appropriately, a talus fracture ...
The posterior talocalcaneal articulation is formed by a concave surface of the talus and a convex surface of the calcaneus. [3] The sustentaculum tali forms the floor of middle facet, and the anterior facet articulates with the head of the talus, and sits lateral and congruent to the middle facet. In some people the middle and anterior facets ...
