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.
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.
Patellofemoral joint complication is among the leading causes for the failure of primary total knee replacement. When the joint wears down and a total knee replacement surgery is recommended, one of the goals of the femoral component is to restore the trochlear groove in such a way that the patella follows its natural pathway during knee movement. Exactech performed a study to understand the native, healthy trochlear groove.
Finding out that you are going to have a baby may be one of the happiest days of your life. Sadly for one family in New York, the joy quickly turned to fear and uncertainty when they found out their baby would be born with a complex form of congenital heart disease.
Standard orthopaedic plating systems don’t always match a patient’s anatomy. Prof. Dr. Stockmans used the Mimics Innovation Suite to optimize the design of a hand plating system for an optimal fit through virtual design iterations.
At the King Faisal Specialist Hospital & Research Centre in Saudi Arabia, Dr. Mansour AlJufan and his team are treating patients with structural and congenital heart defects. Dr. AlJufan recognized early on that 3D-printed models of a patient’s anatomy could greatly assist in planning complex interventional procedures.
World-record-holder Paula Radcliffe ran her first race in two years, in preparation for the London Marathon, thanks to RS Print’s 3D-printed dynamic custom insoles designed specifically for her anatomy and dynamic gait analysis.
Congenital heart defects affect eight out of every one thousand newborns. This case explored the feasibility of using a 3D-printed, patient-specific, compliant model of a patient’s heart anatomy for pre-surgical planning.
