  25. Create a 3D Hand Model and Other Models with STL Files Anatomically speaking, the bones found within the upper limbs help us to perform incredible feats, such as holding and grasping objects. While we may not see these types of tasks as anything extraordinary, it does take five bone and muscle regions (shoulder, axilla, arm, forearm, and hand) to help us complete all the things we do with our hands and arms, such as swing a bat, write a letter, create a painting, and others too numerous to list. For all the reasons we've just mentioned, embodi3D® is proud to introduce some of our favorite uploads, including a 3D hand model, upper limbs, wrists, shoulders, and other 3D printer-ready models that have been shared with the embodi3D® community. While these CT-converted STL files have been used in pre-operative planning and for purposes of education, these uploads will appeal to anyone with an interest in the human form. An article in the International Journal of the Care of the Injured (Injury) revealed how 3D-printed models give orthopedic surgeons tactile and visual experience. As a sensory and reference tool, these models helped them to better understand a patient's unique anatomy and pathology prior to orthopedic surgery. 3D-printed models converted from 2D and 3D CT scans have made fracture line comminution diagnoses more accurate. Patients that can experience a scan on a three-dimensional scale are better equipped mentally to understand the pathology and the surgical procedure necessary to its correction. To download and create 3D-printed models from STL files and CT scans, be sure to register with embodi3D® today! 1. A Highly Detailed Hand 3D Model in STL Format User Phil H uploaded this incredibly detailed anatomically correct hand 3D model to help visualize the hand bones, including the carpus, and metatarsal. The human hand has 27 distinct bones, which allow us to complete a range of tasks. Amazingly, the number of bones in the hand can vary from person to person due to the presence of sesamoid bones, which are essentially bones that are embedded within a muscle or tendon, as is the case with hands. Download this model and create your anatomical hand model! 2. A 3D-Printed Model of an Elbow Joint (Converted from CT Scan) The elbow is one of the largest joints in the body. In conjunction with the shoulder joint and wrist, the elbow gives the arm much of its versatility, as well as structure and durability. This elbow joint was generated from real CT scan data and is thus anatomically accurate as it comes from a real person. It shows the distal humerus, the olecranon as it sits in the olecranon fossa, the two humeral epicondyles, and the distal radius and radial head. There are full size and double size files available. The enlarged double size file shows anatomy in terrific detail. 3. Detailed 3D Model of Hand and Wrist Bones in STL An embodi3D® user going by "than" uploaded this detailed 3D model featuring the hand and wrist bones. Even the joint surfaces are shown in remarkable detail. 4. 3D Rendering from CT Scan of a Shoulder Joint with Multiple Epiphyseal Dysplasia This 3D model created on embodi3D® features a shoulder with epiphysis dysplasia. The imaging findings include the following : Minor epiphyseal involvement, severe involvement (hatchet head group) ,malformed humeral head; broad metaphysis; bowing of the proximal shaft; hypoplasia of the glenoid. If this topic interests you, you may find Matt Johnson's write-up on how 3D printing is being used in cancer screens highly interesting. 3D printing has also been called the "new frontier in oncology research" by The World Journal of Clinic Oncology. 5. 3D Model of Undifferentiated Pleomorphic Spindle Cell Sarcoma This 3D model represents a case of undifferentiated pleomorphic spindle cell sarcoma implicating the right parascapular region of a 61 years old male. The patient represented with lung metastasis and was treated by surgical excision follower by chemotherapy as well as radiotherapy. A cross sectional CT image is attached showing the lesion in axial, coronal and sagittal planes. Unfortunately pleomorphic undifferentiated sarcoma has an aggressive biological behaviour and a poor prognosis. Pleomorphic undifferentiated sarcomas can occur almost anywhere in the body, they have a predilection for the retroperitoneum and proximal extremities. They are usually confined to the soft tissues, but occasionally may arise in or from bone. 6. An Amazing 3D-Printable Model of a Hand An awesome 3D model of the hand´s bones with carpus and metatarsal detailed. 7. Shoulder and Humerus 3D Model Converted from CT Scan This shoulder and humerus was generated from real CT scan data and is thus anatomically accurate as it comes from a real person. It shows the left scapula, humerus, proximal radius and ulna bones, and the shoulder and elbow joints. The humerus has been joined to the scapula at the glenohumeral joint to form one solid piece. 8. A Wrist Fracture Shown in Stunning 3D Detail A great 3D model showing a wrist´s fracture. 9. STL File Showing a Three-Dimensional Model of a Hand and Fingers In this terrific 3D model, the skin surfaces of the hand, fingers, and nails are shown. This is a great demonstration of how the different tissue filters on embodi3D® can creating stunningly realistic renderings. 10. 3D Imaging Tendons of the Hands and Wrists Tendons are fibrous cords, similar to a rope, and are made of collagen. They have blood vessels and cells to maintain tendon health and repair injured tendon. Tendons are attached to muscles and to bone. As the muscle contracts it pulls on the tendon and the tendon moves the bone to which it is attached as well as any joints it crosses. Our growing library of 3D anatomical models also features muscles and tendons of the lower extremities. FCR TENDON The flexor carpi radialis tendon is one of two tendons that bend the wrist. Its muscle belly is in the forearm and then travels along the inside of the forearm and crosses the wrist. It attaches to the base of the second and third hand bones. It also attaches to the one of the wrist bones, the trapezium. FCU TENDON The flexor carpi ulnaris tendon is one of two tendons that bend the wrist. Its muscle belly is in the forearm. The tendon travels along the inside of the forearm on the side of the small finger and crosses the wrist. It attaches to the wrist bone, the pisiform, and as well as the 5th hand bone. ECRB TENDON The extensor carpi radialis brevis tendon is one of 3 tendons, including ECRL and ECU, which act together to bend back the wrist. Its muscle belly is in the forearm and then travels to the thumb side of the wrist on the back part of the forearm. Along with the ECRL, it attaches to the base of the hand bones. It is shorter and thicker than the ECRL ECRL TENDON The extensor carpi radialis longus tendon acts along with the ECRB and ECU to bend back the wrist. ECRL and ECRB also help bend the wrist in the direction of the thumb. Its muscle belly is in the forearm. It is thinner and longer than ECRB. It travels along the back aspect of the forearm and attaches to the base of the hand bones. ECU TENDON The extensor carpi ulnaris tendon works along with the ECRL and ECRB to straighten the wrist. It differs from these other two tendons in that it moves the wrist in the direction of the pinky. Its muscle belly is in the forearm. The tendon travels along the back forearm, through a groove in the ulna, and attaches to the base of the hand bones. References 1. Osagie, L., Shaunak, S., Murtaza, A., Cerovac, S., & Umarji, S.

  26. New embodi3d users have uploaded great 3d models with excellent details! Here are the best from this week, we invite you join our community and discover this cutting edge technology of today and the future in the medical field. Sign up it´s easy! 1. A stl file showing the normal kidney location AABERNETHY uploaded this excellent 3D model. The kidneys are paired retroperitoneal structures that are normally located between the transverse processes of T12-L3 vertebrae. 2. Lumbar spine with scoliosis from a stl file In complex spinal disorders as scoliosis, the correction procedure is often very challenging as unexpected pedicle absence and vertebral rotations can be discovered intraoperatively, posing great risk of neurovascular lesions during the operation. Apparently, current visualization modalities as planar radiographic image and CT scans are not qualified to provide necessary anatomic overview of the affected spinal segments, even the CT with 3D reconstruction can only provide the image without tactile feedback. Therefore, 3D printing is very promising in the personalized treatment of complex spinal disorders. 1 747Larry@gmail.com 3. A CT abdomen and pelvis showing muscle tissue The role of 3D-printed models from DICOM images continues to expand and is fueled by the growing realization that intraoperative utilization of 3D images is not as efficient as having a physical model identical to patient structures, particularly for highly complex interventions. Further reductions in morbidity, mortality, and operating room time are inevitable. Uploaded by Azeem 4. Maxillofacial CT scan Shin uploaded this maxillofacial ct scan with good detail. It shows the paranasal sinuses and teeth. 5. Head/Skull 3d model from a STL file processed Dr. Gutierrez uploaded this excellent skull 3D model with exquisite detail. 6.

  27. In this week's post, we feature some exceptional 3D-printable orthodontic, maxillofacial, and dental scans, including the orbits of the skull, lower teeth, as well as a severe case o jaw bone cavitation. Those practicing in dentistry or orthodontia have likely read about 3D printing's use as an educational tool among colleagues, students, and patients — but, this is just the beginning. A recent article in The Angle Orthodontist highlighted a study by Indiana University School of Dentistry in which it was found that "Dental models reconstructed by FDM (fused deposition modeling) technology had the fewest dimensional measurement differences compared to plaster models." Dental 3D printing will continue to advance, and a future where high-speed digital X-rays and stereolithography-generated 3D dental models seems all but certain. We may even see prosthodontists use a 3D printing process for dentures or implant-supported crowns.

Dr. Mike created this model by using the democratiz3D® service. #4. Lower Jaw and Teeth 3D Model Member mjgillis uploaded this 3D-printable model of a human mandible. This is one example of how a three-dimensional view can illuminate the seriousness of a maxillofacial issue, such as the heavy cavitation (bone loss) in the mandible. #5. Using 3D Models for Dental Implant Patient Eligibility Titanium root implants require a strong jawbone. Using 3D models of tooth-supporting bone matter can help select ideal candidates for dental implants. A special thank you to embodi3D® user mjgillis for sharing this under a Creative Commons (CC) license! #6. Is it a 3D Model of a Mandible or a Plaster Cast? This STL file was uploaded to the Dental, Orthodontic, Maxillofacial forum by embodi3D® member JAWSDOC and serves as a great demonstration of how 3D-printed mandible/maxilla models may someday replace traditional plaster casts. #7. A 3D Model of the Zygomatic, Maxilla, and Orbital Rims of a Human Skull Member Hisham uploaded this file to our Dental, Orthodontic, Maxillofacial forum. This is a detailed, 3D-printable representation of the cavities, curvature, and structure of the orbital, maxilla, zygomatic, and nasal bones. #8. Mandible Fractures Highlighted in a 3D-Printable Model Sometimes, scientific inquiries create more questions in lieu of solutions. This 3D-printable model has us wondering if augmented reality-assisted devices may someday replace endoscopes in the treatment of parasymphyseal and subondylar mandibular fractures. Beyond the possibilities, this 3D-printable fractured mandible combines both art and science; truly a great contribution to the embodi3D® community. Thank you, skullman! References 1.

This STL file was created using contrast-enhanced CT scans, and this upload wins our hearts for its detailed anatomy and exquisite details. 3. STL File of Anterior Muscles of a Human Torso A big "thank you" to Infinity Print for uploading this STL file featuring the sternocleidomastoid, deltoid, pectoralis major, brachioradialis, abductor longus, and other highly detailed anterior muscles of the torso. 4. A 3D-Printable Model of a Dilated Biliary System In this upload from an MRCP image, user nevitdilmen uploaded a detailed file of a dilated biliary system (tree). This patient has a benign biliary stricture, and this 3D-printable rendering will serve as a great tool in the surgical process of correction the obstruction and fixing the hydropic gallbladder. 5. Scoliosis Example as a 3D-Printable STL File User hewtech uploaded a 3D-printable STL file to the Spine and Pelvis forum depicting a severe case of scoliosis, a disorder that causes an abnormal curve of the spine, or backbone. The spine has normal curves when looking from the side, but it should appear straight when looking from the front. Kyphosis is a curve in the spine seen from the side in which the spine is bent forward. There is a normal kyphosis in the middle (thoracic) spine. Lordosis is a curve seen from the side in which the spine is bent backward. There is a normal lordosis in the upper (cervical) spine and the lower (lumbar) spine. People with scoliosis develop additional curves to either side of the body, and the bones of the spine twist on each other, forming a "C" or an "S" shape in the spine. You may also want to check out the upload by user markchui, showing another highly detailed rendering of a patient with scoliosis. 6. Full-Size, 3D-Printable Human Left Foot in STL Format GMorein uploaded full-size, human left foot 3D rendering to the Extremity, Lower (Leg) forum.
