Smith & Nephew launched its DYONICS PLAN Hip Impingement Planning System at the American Academy of Orthopaedic Surgeons (AAOS) annual meeting in New Orleans in March. Unlike standard imaging tools, DYONICS PLAN is a revolutionary 3D software system that allows surgeons to visualise, assess and generate a comprehensive surgical report for each patient’s unique Femoroacetabular impingement (FAI) surgery before that patient even enters the operating room.

“Performing impingement surgery in the hip without the report is like putting in a total knee without cutting guides,” says Dr Bryan Kelly of New York. “DYONICS PLAN takes the guesswork out of every case.”

DYONICS PLAN provides a standardised and repeatable way of assessing hip impingement treatment options based on data from low-dose1 CT scans. The software, installed on a surgeon’s computer, also allows for interactive adjustments based on a surgeon’s clinical experience.

Using the DYONICS PLAN 3D model of the patient’s joint, a surgeon can perform a variety of dynamic range-of-motion (ROM) simulations to identify the degree and location of hip impingement. The ROM feature can also be used to individualise a surgical plan based on a patient’s lifestyle or sports-specific motion, or to assess impact of different surgical strategies on patient outcomes. Once finalised, the system generates a comprehensive surgical plan than can be exported into either HTML or PDF format.

“DYONICS PLAN offers surgeons the ability to understand and address a patient’s hip impingement on a level that goes beyond anything possible with standard imaging tools,” explains Brad Cannon, President, Endoscopy, Trauma and Extremities for Smith & Nephew. “Because it tells a more complete story about each patient’s impingement and how best to surgically treat it, it also provides an exceptionally visual tool for patient communication.”
