Smith & Nephew Planning Software Takes the Guesswork out of Hip Arthroscopy for Impingement

Smith & Nephew will launch its DYONICS PLAN Hip Impingement Planning System at this week’s American Academy of Orthopaedic Surgeons (AAOS) annual meeting in New Orleans. The company describes its system as a revolutionary 3D software system that allows surgeons to visualize, assess and generate a comprehensive surgical report for each patient’s unique Femoroacetabular impingement (FAI) surgery before that patient ever enters the operating room.


FAI is a condition where the bones of the hip are abnormally shaped, the hip bones consequently rubbing against each other and causing damage to the joint, including cartilage damage and bone spurs.

DYONICS PLAN provides a standardized and repeatable way of assessing hip impingement treatment options based on data from low-dose CT scans. The software, which is easily 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 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 individualize 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 finalized, the system generates a comprehensive surgical plan than can be exported into either HTML or PDF format.

Physician comments

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

Company comments

“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.”
