This is the normal right leg skin model (including foot) 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.
Landmarks of the lower extremity consist of bony and muscular landmarks. Proximally, the extensor mechanism consists of the quadriceps tendon, patella, and the tibial tuberosity, which is located on the anterior proximal tibia, where the patellar tendon attaches. On the anteromedial surface of the tibia is Gerdy's tubercle, where the sartorius, gracilis, and semitendinosus attach. Laterally, the head of the fibula may be palpated, which is the attachment for the posterolateral corner structures of the knee joint. The peroneal nerve wraps around the fibular neck, and a tinel’s sign may be elicited due to its superficial position at this location.
Distally, the anterior ankle joint may be palpated. Pain with palpation may be indicative of osteoarthritis if general or an osteochondral defect if localized. The medial and lateral malleoli are located on either side of the tibiotalar joint, respectively and are the site of common ankle fractures. Posteriorly, the Achilles tendon inserts on the calcaneus. A defect along this tendon may be a sign of a tendon rupture. The superficial peroneal nerve can possibly be isolated on the lateral aspect of the dorsal foot with full plantarflexion of the fourth ray.
This model was created from the file STS_014.
