TS-002958 — Hip distraction, or arthrodiastasis, is a surgical option for end-stage diseases of the hip, such as Legg Calve Perthes disease, avascular necrosis, and end-stage osteoarthritis. The procedure improves mobility, decreases pain, and prevents further wear to avoid a total hip arthroplasty. However, the standard of care procedure requires an external device that uses large pins that are kept for 3-4 months which can be distressing for pediatric patients. NCH inventors have developed a completely internal hip-spanning device that allows for distraction and articulated hip motion. This device will likely reduce the problems associated with an external device such as infection, procedure failure, and psychosocial concerns.

TS-002957 — Available 3D spine models do not optimize properties to simulate real-life bones, ligaments, tendons, viscoelasticity, or resistance that is present in a patient. Spine models are used by both surgeons and researchers for surgical planning, simulation, training, research and medical device development. By optimizing 3D printing materials, NCH inventors can produce patient-specific spine models that replicate the viscoelastic properties of the spine for a more accurate rendition. In addition to precise surgical planning, another benefit of utilizing viscoelastic accurate models is further medical device innovation to optimize surgical outcomes.
