BONES OF FOOT CODE Flashcards
Front
Back
What are the three main groups of bones in the foot?
The three main groups are:\n1. Tarsals (7 bones, located in the ankle area)\n2. Metatarsals (5 bones, connecting phalanges to tarsals)\n3. Phalanges (bones of the toes, with three phalanges per toe except the big toe, which has two)
What are the regions of the foot?
The foot is divided into three regions:\n1. Hindfoot – Talus and Calcaneus\n2. Midfoot – Navicular, Cuboid, and Cuneiforms\n3. Forefoot – Metatarsals and Phalanges
What bones make up the proximal group of tarsals?
The proximal group of tarsal bones consists of the Talus and Calcaneus.
What is the function of the Talus bone?
The Talus transmits the weight of the entire body from the tibia to the foot, acting as a key stabilizer for the ankle.
What articulations are present in the Talus?
The Talus has three articulations:\n1. Superiorly – with the tibia and fibula at the ankle joint.\n2. Inferiorly – with the calcaneus at the subtalar joint.\n3. Anteriorly – with the navicular at the talonavicular joint.
What are the clinical implications of Talus fractures?
Talus fractures, particularly in the neck region, can lead to avascular necrosis due to interrupted blood supply. These fractures are often caused by high-energy trauma, such as dorsiflexion injuries.
What articulations are present in the Calcaneus?
The Calcaneus has two articulations:\n1. Superiorly – with the Talus at the subtalar joint.\n2. Anteriorly – with the Cuboid at the calcaneocuboid joint.
What are the clinical implications of Calcaneus fractures?
Calcaneus fractures are common after axial loading, such as falls from height, and may result in arthritic changes in the subtalar joint. Pain may occur with inversion and eversion, making walking difficult.
What is the function of the Navicular bone in the foot?
The Navicular bone articulates with the Talus, three Cuneiforms, and the Cuboid. It is important for maintaining the medial arch of the foot and provides a surface for the tibialis posterior tendon attachment.
What bones are included in the distal group of tarsals?
The distal group consists of the Cuboid and three Cuneiforms (lateral, intermediate, and medial).
What is the clinical relevance of Metatarsal fractures?
Metatarsal fractures can result from a direct blow, stress fractures due to repetitive strain, or avulsion injuries caused by excessive inversion, particularly in athletes.
