Bespoke 3D Anatomical Modeling for 5-Year-Old Jalanea

Solutions: Mimics inPrint

Born with Down syndrome and undergoing treatment for leukemia, Jalanea was diagnosed at 5 years old with Atlanto-axial instability – a dangerous point of weakness between spine and skull. Clinicians at Ochsner Hospital for Children used 3D anatomical modeling, generated by Materialise’s Mimics inPrint software, to help plan and successfully execute a complicated procedure that would ultimately save a brave little girl’s life.

Reconstructing a Painful Clavicle

Solutions: Surgical Guides

A young patient with a painful deformity in his clavicle, which was causing him both cosmetic and functional issues, consulted Dr. Alexander Van Tongel. Dr. Van Tongel worked with Materialise clinical engineers for pre-operative 3D planning and 3D-printed surgical guides for a corrective osteotomy.

Time Saved in the OR by Identifying the Right Components for Knee Revision in advance

Solutions: Materialise OrthoView

Digital pre-operative planning allows the surgeon to easily assess the size of components required, as well as other factors that the duration of the procedure. Having considered a variety of options in advance of the procedure, the surgeon was able to ensure both the equipment and his staff were prepared, thus saving valuable time in the OR.

Corrective Osteotomy of the Distal Radius on the Right

Solutions: Surgical Guides

Treating a young patient born in 1993 who had an injury in 2009 with a malunion of the distal radius, Dr. Peter Axelsson from the Sahlgrenska Hospital in Sweden worked together with the Materialise Clinical Engineers for 3D-printed anatomical models, 3D analysis and planning, and 3D-printed patient-specific guides. This case was one of the first cases he did with Materialise.

Complex Defect Following TSA Calls For 3D Printing Solution

Solutions: SurgiCase

A 64-year-old patient suffered from severe complications related to total shoulder arthroplasty performed several years ago. His diagnosis claimed a defect with abnormal ossification surrounding the glenoid. Due to the complexity and unusual size of this particular defect, implementing a patient-specific 3D-Printed Glenius implant seemed to offer the best solution. Prof. Dr. Stefaan Nijs (Belgium) proceeded with a two-stage revision procedure based on detailed 3D preoperative planning.

Planning a Total Knee Revision

Solutions: Materialise OrthoView

The patient, an 86 year-old woman who was the primary caregiver for her husband, had previously been an active person in the local community. She was experiencing increasing right knee pain and deformity and was unable to walk without the use of a cane. A physical examination revealed antero-posterior and medial instability with 10-degree hyperextension to 90-degree flexion

 

Templating a Complex Modular stem for a THR on a Dysplastic Hip & Planning a Subtractive Osteotomy

Solutions: Materialise OrthoView

OrthoView is able to present the full range of options and compatibilities available with complex modular prostheses on-screen so that the surgeon does not need to memorize them. The surgeon is also able to identify that the correct amount of offset is achievable with the chosen prosthesis.

Planning a total knee replacement & tibial osteotomy to replace & realign the knee joint

Solutions: Materialise OrthoView

The patient has a history of hypophosphatemic rickets. The associated bone abnormalities and leg malalignment had been addressed by bilateral closing wedge tibial osteotomies when the patient was approximately 40 years of age. The patient was now experiencing pain in both knees and was having difficulty walking.

Life-transforming shoulder surgery makes 60 year old woman fulfill her daily activities again

A 60 year old lady was suffering from shoulder pain and limited range of motion. Analysis of the medical images indicated a devastating shoulder arthrosis with severe medialization and erosion of the glenoid. Due to a complete loss of the glenoid vault, implantation of a classic pegged baseplate for reverse total shoulder was not an option. In addition, interposition of a massive bone graft would have little chance for ingrowth and survival, hence little chance to offer sufficient stability.

Life-transforming hip surgery makes 81 year old sing and whistle again

At the age of 81, the patient was suffering from a Paprosky type 3B defect and already underwent hip revision surgeries prior to seeking the help of Mr. Dunlop. He is not alone, because data from joint registries show that 27% of the revisions is not an initial one and those re-revisions have a 3 times higher chance of failure compared to initial revisions.

Restoring Hip Biomechanics with Cemented Femoral Hip Implants: A 3D Templating Study Using Scripting

Solutions: Mimics Innovation Suite, Scripting

Total hip replacement is widely considered a very successful surgery to relieve pain and restore mobility to patients. Since the shape of every patient's femur is different, the femoral offset, anteversion angle and length can vary widely between patients. Therefore, to achieve good functional results, an accurate restoration of hip biomechanics with appropriate implant and sizing options is essential.

Automating Key Components of Finite Element Research

Solutions: FEA, Mimics Innovation Suite, Scripting

In total hip replacement surgery, short hip stems are presumed to reduce proximal stress shielding compared to traditional, long stems. Belgian researchers virtually implanted a commercially available calcar-guided short stem in a series of bones with deviating proximal geometry and performed finite element analyses. Given the large number of FEA models that had to be created, they used an automated methodology.
