    The sternum is formed by three bones; the manubrium, the sternal body and the xiphoid process (xiphisternum). These bones articulate together by hyaline cartilage with a fibro-cartilaginous disc to form the anterior and midline portion of the chest wall. The has many articulations, where the manubrium articulates with the first rib and the clavicle while the sternal body articulates with the second to seventh ribs as well as the costal cartilages. This 3D model was created from the file STS_044. The source CT scan used to create this model can be found here.

    The cervical spine is the upper most spines forming the spinal column, extending from the skull base to the level of the thoracic vertebra (the spines with attached ribs). The cervical spines are usually seven and the main function is to support the skull and to protect the spinal cord. Apart from the first cervical vertebra (atlas) and the second vertebra (axis), the other vertebral bodies share a general anatomical appearance: Oval shaped vertebral bodies with wide vertebral arch, large vertebral foramina and long spinous processes. This particular model shows parts of the mandible as well as the hyoid bone. This 3D model was created from the file STS_044. The source scan used to create this file can be found here.

    The knee joint is formed by three bones: the femur, the tibia and the patella. the knee joint is the largest synovial joint and provides the flexion and extension movements of the leg as well as relative medial and lateral rotations while in relative flexion. The knee joint articulations are two condylar joints between the femur and the tibia as well as a joint between the patella and the femur. Although the fibula is closely related to the knee joint but it doesn't share in articulation. The knee joint is also formed by some ligaments and cartilage called (menisci) which are best imaged by MRI. This 3D model was created from the file STS_045. The source scan be be found here.

    This 3D model represents a case of low grade myxoid liposarcoma affecting the right thigh muscle of a 46 years old male. The model shows a comparison of both lower limbs muscle with a notable enlargement / swelling of the right thigh muscles. The tumor is not causing a significant muscular deformity, therefor a cross sectional CT image is attached showing the lesion in axial, coronal and sagittal planes. Myxoid liposarcoma is the second commonest for of liposarcoma and usually represents an intermediate grade. Liposarcomas in general are mostly seen in extremities and the most common affected muscles are of the thigh. This 3D model was created from the file STS_044. The source scan can be found here.

    This 3D model represents a case of high grade extraskeletal osteosarcoma affecting the left adductor muscle of a 27 years old male. The patient was treated by surgical excision follower by chemotherapy. A cross sectional CT image is attached showing the lesion in axial, coronal and sagittal planes. Extraskeletal osteosarcoma (ESOS) is one of the rare malignant neoplasms that affects the mesenchymal tissues such as the retroperitoneum as well as the soft tissue of the extremities with no significant connection to the related bones. Extraskeletal osteosarcoma usually affects people between 40 years and 80 years and is more common in males with a documented risk factor which is radiation exposure. The common presentation is enlarged or swollen soft tissue which could be painful or not. Extraskeletal osteosarcoma is diagnosed by plain x-ray, CT or MRI as the soft tissue shows variable calcification. The most common affected sites are the lower extremities followed by upper extremities and retroperitoneum. Most of patients are presented with metastasis at time of diagnosis which leads to a generally poor prognosis. The usual treatment is surgical excision of the primary tumor as the tumor is insensitive to chemotherapy or radiotherapy. This 3D model was created from the file STS_045. The source scan can be found here.

    This model is the right foot and ankle muscle rendering of a 65-year-old male with left thigh myxoid fibrosarcoma. At the time of diagnosis, the patient had metastases to his lungs. The patient therefore underwent neoadjuvant radiotherapy, surgery, and adjuvant chemotherapy and was found to have an intermediate grade lesion at the time of diagnosis. The patient unfortunately died 9.5 months after diagnosis. This is an STL file created from DICOM images of his CT scan which may be used for 3D printing. The primary motions of the ankle are dorsiflexion, plantarflexion, inversion and eversion. However with the addition of midfoot motion (adduction, and abduction), the foot may supinate (inversion and adduction) or pronate (eversion and abduction). In order to accomplish these motions, muscles outside of the foot (extrinsic) and muscles within the foot (intrinsic) attach throughout the foot, crossing one or more joints. Laterally, the peroneus brevis and tertius attach on the proximal fifth metatarsal to evert the foot. The peroneus longus courses under the cuboid to attach on the plantar surface of the first metatarsal, acting as the primary plantarflexor of the first ray and, secondarily, the foot. Together, these muscles also assist in stabilizing the ankle for patients with deficient lateral ankle ligaments from chronic sprains. Medially, the posterior tibialis inserts on the plantar aspect of the navicular cuneiforms and metatarsal bases, acting primarily to invert the foot and secondarily to plantarflex the foot. The flexor hallucis longus inserts on the base of the distal phalanx of the great toe to plantarflex the great toe, and the flexor digitorum inserts on the bases of the distal phalanges of the lesser four toes, acting to plantarflex the toes. The gastrocnemius inserts on the calcaneus as the Achilles tendon and plantarflexes the foot. Anteriorly, the tibialis anterior inserts on the dorsal medial cuneiform and plantar aspect of the first metatarsal base as the primary ankle dorsiflexor and secondary inverter. The Extensor hallucis longus and extensor digitorum longus insert on the dorsal aspect of the base of the distal phalanges to dorsiflex the great toe and lesser toes, respectively. This model was created from the file STS_023.

    This model is the left foot and ankle skin rendering of a 65-year-old male with left thigh myxoid fibrosarcoma. At the time of diagnosis, the patient had metastases to his lungs. The patient therefore underwent neoadjuvant radiotherapy, surgery, and adjuvant chemotherapy and was found to have an intermediate grade lesion at the time of diagnosis. The patient unfortunately died 9.5 months after diagnosis. This is an STL file created from DICOM images of his CT scan which may be used for 3D printing. Topographical landmarks of the foot and ankle consist of muscular, tendinous, and bony structures. Proximally, the superficial muscles of the anterior (tibialis anterior), lateral (peroneals) and posterior (gastrocnemius) compartments may be palpated. Anteriorly, the tibialis anterior tendon crosses the ankle joint and is used as a landmark for ankle joint injections and aspirations, where the practitioner will place the needle just lateral to the tendon. Posteriorly, the gastrocnemius and soleus converge to form the Achilles tendon. Ruptures of the tendon as well as tendinous changes due to Achilles tendinopathy may be palpated. At the level of the ankle joint, the joint line, medial malleolus (distal tibia) and lateral malleolus (distal fibula) may be palpated. The extensor hallucis longus and extensor digitorum longus tendons are visible at the surface of the dorsal foot. The extensor digitorum brevis muscle belly is seen on the dorsum of the lateral foot. On the plantar foot, the plantar fascia may be palpated. Nodules associated with plantar fascial fibromatosis may be palpated here. Plantar fasciitis is also diagnosed when pain is associated with palpation of the insertion of the plantar fascia on the medial heel. Other common pathologies on the plantar foot are ulcerations associated with diabetic neuropathy and other neuropathic conditions. This model was created from the file STS_023.

    This model is the left foot and ankle bone rendering of a 65-year-old male with left thigh myxoid fibrosarcoma. At the time of diagnosis, the patient had metastases to his lungs. The patient therefore underwent neoadjuvant radiotherapy, surgery, and adjuvant chemotherapy and was found to have an intermediate grade lesion at the time of diagnosis. The patient unfortunately died 9.5 months after diagnosis. 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. 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. Radiographic analysis of an ankle after injury should include the so-called “mortise view”, upon which measurements can be made to determine congruity of the ankle joint. Normal measurements include >1 mm tibiofibular overlap, </= 4mm medial clear space, and <6 mm of tibiofibular clear space. The talocrural ankle is measured by the bisection of a line through the tibial anatomical axis and another line through the tips of the malleoli. Shortening of the lateral malleolus can lead to an increased talocrural angle. 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_023.

    This model is the left lower extremity skin rendering of a 65-year-old male with left thigh myxoid fibrosarcoma. At the time of diagnosis, the patient had metastases to his lungs. The patient therefore underwent neoadjuvant radiotherapy, surgery, and adjuvant chemotherapy and was found to have an intermediate grade lesion at the time of diagnosis. The patient is still living with the metastatic disease at 2.5 years since diagnosis. This is an STL file created from DICOM images of his CT scan which may be used for 3D printing. Myxoid fibrosarcoma (or myxoid MFH) is the most common subtype of MFH, at about 10%-20% of cases. Clinically, the tumor presents as a deep, slow-growing, painless mass. It is located more commonly in the lower extremities and retroperitoneum. Imaging on MRI demonstrates a mass with low signal intensity on T1-weighting imaging, and high signal intensity on T2-weighted imaging. On histology, a myxoid background is present with a storiform (or cartwheel) pattern seen on low-power imaging, seen in fibrosarcomas. A “myxoid background” is composed of a clear, mucoid substance. Treatment includes radiation, wide surgical resection, and chemotherapy in selected cases. However, the 5-year survival is 50%-60% depending on size, grade, depth and presence of metastasis. The term “malignant fibrous histiocytoma” was coined in the 1960s by Margaret R. Murray when histology a sarcoma demonstrated an appearance like histiocytes, with characteristics of phagocytosis and a pleomorphic pattern. With further research, this entity was identified to have a wider range of appearances with a fibrous characteristic. Today, these sarcomas are known as “pleomorphic sarcomas.” Recently, a change in the understanding of soft tissue tumors has purported that MFH is not a specific type of cancer, but a common morphologic pattern shared by unrelated tumors. One school of thought states that this morphologic pattern is shared by tumors as a common final pathway in cancer progression whereas another school of thought believes that true pleomorphic sarcomas are the result of a transformation from mesenchymal stem cells. Future research into understanding the pathway of these sarcomas and progression will help to target specific therapies and, hopefully, eventual cures. This model was created from the file STS_022.

    This model is the left lower extremity bone rendering of a 65-year-old male with left thigh myxoid fibrosarcoma. At the time of diagnosis, the patient had metastases to his lungs. The patient therefore underwent neoadjuvant radiotherapy, surgery, and adjuvant chemotherapy and was found to have an intermediate grade lesion at the time of diagnosis. The patient is still living with the metastatic disease at 2.5 years since diagnosis. This is an STL file created from DICOM images of his CT scan which may be used for 3D printing The lower extremity consists of the femur, tibia, fibula, and foot. The femur has an anterior bow of differing degrees, which is important to understand when fixing a femur fracture with an intramedullary nail to not penetrate the anterior cortex. Distally, the femur includes the medial and lateral femoral condyles, which articulate with the proximal tibia to form the knee joint, as well as the trochlea anteriorly, which articulates with the patella. The proximal tibia includes the medial plateau (which is concave) and the lateral plateau (which is convex). The Proximal tibia has a 7-10 degree posterior slope. On the anterior proximal tibia, the tibial tuberosity, where the patellar tendon attaches. On the anteromedial surface of the tibia is Gerdy's tubercle, where the sartorius, gracilis, and semitendinosus attach. The distal tibia creates the superior and medial (plafond and medial malleolus) of the ankle joint. The proximal fibula is the attachment for the posterolateral corner structures of the knee joint. The peroneal nerve wraps around the fibular neck. The distal fibula is the lateral malleolus and a common site for ankle fractures. This model was created from the file STS_022.

    This model is the right leg skin rendering of a 65-year-old male with left thigh myxoid fibrosarcoma. At the time of diagnosis, the patient had metastases to his lungs. The patient therefore underwent neoadjuvant radiotherapy, surgery, and adjuvant chemotherapy and was found to have an intermediate grade lesion at the time of diagnosis. The patient is still living with the metastatic disease at 2.5 years since diagnosis. 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. Topographical landmarks of the foot and ankle consist of muscular, tendinous, and bony structures. Proximally, the superficial muscles of the anterior (tibialis anterior), lateral (peroneals) and posterior (gastrocnemius) compartments may be palpated. Anteriorly, the tibialis anterior tendon crosses the ankle joint and is used as a landmark for ankle joint injections and aspirations, where the practitioner will place the needle just lateral to the tendon. Posteriorly, the gastrocnemius and soleus converge to form the Achilles tendon. Ruptures of the tendon as well as tendinous changes due to Achilles tendinopathy may be palpated. At the level of the ankle joint, the joint line, medial malleolus (distal tibia) and lateral malleolus (distal fibula) may be palpated. The extensor hallucis longus and extensor digitorum longus tendons are visible at the surface of the dorsal foot. The extensor digitorum brevis muscle belly is seen on the dorsum of the lateral foot. On the plantar foot, the plantar fascia may be palpated. Nodules associated with plantar fascial fibromatosis may be palpated here. Plantar fasciitis is also diagnosed when pain is associated with palpation of the insertion of the plantar fascia on the medial heel.

    This model is the left leg muscle rendering of a 65-year-old male with left thigh myxoid fibrosarcoma. At the time of diagnosis, the patient had metastases to his lungs. The patient therefore underwent neoadjuvant radiotherapy, surgery, and adjuvant chemotherapy and was found to have an intermediate grade lesion at the time of diagnosis. The patient is still living with the metastatic disease at 2.5 years since diagnosis. This is an STL file created from DICOM images of his CT scan which may be used for 3D printing. The lower leg is divided into four muscle compartments: the anterior, lateral, superficial posterior, and deep posterior compartments. The anterior compartment is made from the dorsiflexors, including the tibialis anterior, extensor hallucis longus (EHL), extensor digitorum longus (EDL) and peroneus tertius, which are innervated by the deep peroneal nerve. The lateral compartment includes the peroneus longus and peroneus brevis, which assist in foot eversion and are innervated by the superficial peroneal nerve. The superficial posterior compartment includes the gastrocnemius, soleus, and plantaris, which assist in plantarflexion and are innervated by the tibial nerve. The deep posterior compartment is made up of the popliteus, flexor hallucis longus (FHL), flexor digitorum longus (FDL), and tibialis posterior, which mostly assist in plantarflexion and are innervated similarly by the tibial nerve. The primary motions of the ankle are dorsiflexion, plantarflexion, inversion and eversion. However, with the addition of midfoot motion (adduction, and abduction), the foot may supinate (inversion and adduction) or pronate (eversion and abduction). In order to accomplish these motions, muscles outside of the foot (extrinsic) and muscles within the foot (intrinsic) attach throughout the foot, crossing one or more joints. Laterally, the peroneus brevis and tertius attach on the proximal fifth metatarsal to evert the foot. The peroneus longus courses under the cuboid to attach on the plantar surface of the first metatarsal, acting as the primary plantarflexor of the first ray and, secondarily, the foot. Together, these muscles also assist in stabilizing the ankle for patients with deficient lateral ankle ligaments from chronic sprains. Medially, the posterior tibialis inserts on the plantar aspect of the navicular cuneiforms and metatarsal bases, acting primarily to invert the foot and secondarily to plantarflex the foot. The flexor hallucis longus inserts on the base of the distal phalanx of the great toe to plantarflex the great toe, and the flexor digitorum inserts on the bases of the distal phalanges of the lesser four toes, acting to plantarflex the toes. The gastrocnemius inserts on the calcaneus as the Achilles tendon and plantarflexes the foot. Anteriorly, the tibialis anterior inserts on the dorsal medial cuneiform and plantar aspect of the first metatarsal base as the primary ankle dorsiflexor and secondary inverter. The Extensor hallucis longus and extensor digitorum longus insert on the dorsal aspect of the base of the distal phalanges to dorsiflex the great toe and lesser toes, respectively. This model was created from the file STS_022.

    This model is the right thigh muscle rendering of a 49-year-old male with a right medial thigh undifferentiated pleomorphic malignant fibrous histiocytoma (MFH). The patient underwent neoadjuvant radiotherapy, surgery, and adjuvant chemotherapy treatment and was found to have a high-grade lesion at the time of diagnosis. Metastases to his lungs were also found at diagnosis. The patient is still living with the disease at 2 years since diagnosis. This is an STL file created from DICOM images of his CT scan which may be used for 3D printing. Undifferentiated pleomorphic MFH has more recently been classified as Undifferentiated Pleomorphic Sarcoma. This is the most common soft tissue sarcoma in late adulthood, commonly occurring between 55 to 80 years old and most commonly in Caucasian males. Clinically, it presents as a slowly growing mass in the extremities. Biopsy of the lesion demonstrates, as its name implies, an undifferentiated and pleomorphic appearance. Pleomorphism is the pathologic description of cells and nuclei with variability in size, shape, and staining, which is characteristic of a malignant neoplasm. “Undifferentiated” means that the tissue does not appear like an identifiable tissue structure. Treatment consists of wide resection and radiation. Chemotherapy is added in cases of metastasis, most commonly to the lung. Five-year survival is between 35-60% depending on the grade of tumor and metastases. This model was created from the file STS_021.

    This is the normal right foot and ankle skin 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. Topographical landmarks of the foot and ankle consist of muscular, tendinous, and bony structures. Proximally, the superficial muscles of the anterior (tibialis anterior), lateral (peroneals) and posterior (gastrocnemius) compartments may be palpated. Anteriorly, the tibialis anterior tendon crosses the ankle joint and is used as a landmark for ankle joint injections and aspirations, where the practitioner will place the needle just lateral to the tendon. Posteriorly, the gastrocnemius and soleus converge to form the Achilles tendon. Ruptures of the tendon, as well as tendinous changes due to Achilles tendinopathy, may be palpated. At the level of the ankle joint, the joint line, medial malleolus (distal tibia) and lateral malleolus (distal fibula) may be palpated. The extensor hallucis longus and extensor digitorum longus tendons are visible on the surface of the dorsal foot. The extensor digitorum brevis muscle belly is seen on the dorsum of the lateral foot. On the plantar foot, the plantar fascia may be palpated. Nodules associated with plantar fascial fibromatosis may be palpated here. Plantar fasciitis is also diagnosed when pain is associated with palpation of the insertion of the plantar fascia on the medial heel. Other common pathologies on the plantar foot are ulcerations associated with diabetic neuropathy and other neuropathic conditions. This model was created from the file STS_014.

    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.
