    Left knee - Muscle model STL file from converted CT scan

    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_039   The original CT examination can be reviewed at: The 3D bone model created from this scan can be reviewed at: The 3D skin model created from this scan can be reviewed at:

    Normal Right Foot and Ankle Muscle Model 3D Printable STL File Converted from CT Scan

    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.

    Right Thigh Muscle Model 3D Printable STL File Converted from CT Scan

    This model is the right thigh 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 thigh is divided into three compartments: the anterior, posterior, and adductor. The anterior compartment contains the “quadriceps muscles”, made up of the vastus lateralis, vastus medialis vastus intermedius, and rectus femoris, and the sartorius. These muscles are innervated by the femoral nerve (L3-L4), and act to extend the leg. The Sartorius muscle originates at the ASIS and crosses anterior to the quadriceps muscle to insert on the medial tibia in the pes anserinus. The posterior compartment contains the “hamstrings”, made up of the semitendinosus, semimembranosus, and short and long heads of the biceps femoris. These muscles act to flex the leg. All of these muscles are innervated by the sciatic nerve (tibial division) except for the short head of the biceps femoris, which is innervated by the sciatic nerve (peroneal division). The adductor compartment contains the adductor longus, adductor brevis, adductor magnus, and gracilis, which act to adduct the thigh. These muscles are innervated by the obturator, and the adductor magnus has dual innervation with the sciatic nerve. In addition, the obturator externus (a thigh external rotator) and pectineus muscle (thigh flexor and adductor) are located within this compartment.

    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.

    Right Knee Muscle Model 3D Printable STL File Converted from CT Scan

    This model is the right knee 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 knee is a hinge joint that does not have true bony stabilization, so it requires soft tissue static and dynamic stabilizers to prevent excess motion through the joint. In addition, the knee goes through a “screw home” mechanism in which the tibia rotates externally and “locks” into extension during the last 15-20 degrees of extension. Multiple structures, therefore, are needed to work in concert to prevent excess strain through this joint during these daily motions.
     
    On the medial aspect of the knee, the static stabilizers consist of the superficial and deep medial collateral ligaments (MCL) and the posterior oblique ligament (POL). The dynamic stabilizers are the semimembranosus, vastus medialis, medial gastrocnemius, and pes tendons (semitendinosus, gracilis, and sartorius). The lateral stabilizers are best known as the posterolateral corner, and consist of the static stabilizers (lateral collateral ligament (LCL), iliotibial band (ITB), arcuate ligament), and dynamic stabilizers (popliteus, biceps femoris, lateral gastrocnemius). Inside the joint, the anterior cruciate ligament provides resistance to anterior tibial translation varus, and internal rotation, whereas the posterior cruciate ligament provides resistance to posterior tibial translation, varus, valgus, and external rotation.

    This is the normal right leg muscle 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.
     
    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.

    Right Anterior Thigh Pleomorphic Leiomyosarcoma Skin Model 3D Printable STL File Converted form CT Scan

    This model is the bilateral thigh skin rendering of a 56 year old male with a pleomorphic leiomyosarcoma of the anterior compartment of the right thigh. The patient underwent neoadjuvant radiotherapy, surgery, and adjuvant chemotherapy treatment and was found to have an intermediate grade lesion at the time of diagnosis.  However, the tumor metastasized to his lungs, and the patient died 2.5 years after diagnosis. This is an STL file created from DICOM images of his CT scan which may be used for 3D printing.
     
    Leiomyosarcomas are aggressive soft tissue malignancies that are thought to arise from the smooth muscle cells lining small blood vessels. Pleomorphism is the pathologic description of cells and nuclei with variability in size, shape and staining, which is characteristic of a malignant neoplasm. Pleomorphic leiomyosarcoma is an aggressive form of leiomyosarcoma, accounting for approximately 10% of these tumors. The mean age of occurrence is 58 years old, with a range from 31-89 years. These usually occur in the extremities, but may also present in the retroperitoneum/abdominal cavity, chest/abdominal wall, and, occasionally, the scalp. On biopsy, the definition of pleomorphic leiomyosarcoma is the presence of pleomorphic cells in at last two-thirds of the cut section and at least one section of positive staining for smooth muscle. Treatment is early wide resection of the primary lesion and neo-adjuvant or adjuvant chemotherapy and radiation. Tumors may metastasize to the lung. A large primary tumor and presence in the retroperitoneal cavity are poor predictive factors, and about 65% of patients succumb to the disease.

    Normal Left Foot and Ankle Muscle Model 3D Printable STL File Converted from CT Scan

    This is the normal left foot and ankle muscle 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 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.

    • Here is an article on the benefits of using 3D printed temporal bones for surgical training   https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6703115/
    • Valchanov,   I downloaded the file and took a look. I see right ventricular hypertrophy, a large VSD, pulmonary valve atresia/stenosis and an overriding aorta that is also on the right side. I think this is Tetrology of Fallot. It is a cool scan! Dr. Mike
    • Hello Can you give me some background information about the health condition of the patient? The set is excellent, but there is something really wrong with the anatomy of this heart. I want to model it properly.
    • The whole time I was thinking that I'm doing something wrong, because it's impossible for a TAAA to be that big. This was beyond everything I ever saw for 22 years of medical education and experience. But yes, it's THAT big. I segmented the lumen, I added 2 cm margin around it to create a hollow shell, then I added the media of the aneurysmic sack and all the atherosclerotic plaques for extra realism. There was a part of the sack, which went into one of the perihepatic space, but I removed it, b

    • Today we want to share some of the best representations of how embodi3D® members are using democratiz3D® conversions to create a foot 3D model and other skin, tissue, and skeletal features of the lower extremities.   http://ow.ly/4W3B50wL3iA
    • Three-dimensional printing and modeling is a new technology that has exciting applications for rhinoplasty and facial plastic surgery. We now have the ability to 3D print a skull and 3D-printed face models have been used in the facial reconstruction process. We can also use 3D printing to recreate the muscles of the face. These types of models have been used in advanced procedures that help to restore facial features. One notable example from the Mayo Clinic in Minnesota is the 2017 full-facial reconstruction that employed 3D-printed models to reconstruct a face.    Check this post and learn more!
