About This File

This is the normal right foot and ankle bone model of a 56 year old male with right anterior thigh pleomorphic leiomyosarcoma. This is an STL file created from DICOM images of his CT scan which may be used for 3D printing.

 

The ankle is a hinge (or ginglymus) joint made of the distal tibia (tibial plafond, medial and posterior malleoli) superiorly and medially, the distal fibula (lateral malleolus) laterally and the talus inferiorly. Together, these structures form the ankle “mortise”, which refers to the bony arch. The normal range of motion is 20 degrees dorsiflexion and 50 degrees plantarflexion. Stability is provided by the anterior talofibular ligament (ATFL), calcaneofibular ligament (CFL), and posterior talofibular ligament (PTFL) laterally, and the superficial and deep deltoid ligaments medially. The ankle is one of my most common sites of musculoskeletal injury, including ankle fractures and ankle sprains, due to the ability of the joint to invert and evert. The most common ligament involved in the ATFL.

 

The foot is commonly divided into three segments: hindfoot, midfoot, and forefoot. These sections are divided by the transverse tarsal joint (between the talus and calcaneus proximally and navicular and cuboid distally), and the tarsometatarsal joint (between the cuboids and cuneiforms proximally and the metatarsals distally). The first tarsometatarsal joint (medially) is termed the “Lisfranc” joint and is the site of the Lisfranc injury seen primarily in athletic injuries.

 

This model was created from the file STS_014.
