3D Printing + Conventional Imaging for Hip Surgery Planning
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to determine if using a 3D printed model of the hip, alongside regular imaging like X-rays and MRIs, improves planning for hip surgeries to treat femoroacetabular impingement (FAI). FAI occurs when extra bone grows along one or both bones forming the hip joint. Participants will join one of two groups: one will use only conventional imaging, while the other will also use a 3D model. The trial seeks individuals diagnosed with cam-type FAI, excluding those with advanced arthritis or significant hip damage. As an unphased trial, this study provides a unique opportunity to contribute to innovative research that could enhance surgical planning and outcomes.
Do I need to stop my current medications for the trial?
The trial information does not specify whether you need to stop taking your current medications.
What prior data suggests that this 3D printing technique is safe for hip surgery planning?
Research has shown that using 3D printed models to plan hip surgeries can be safe and helpful. In past studies, doctors used these models to prepare for surgeries, which improved planning and allowed them to try out procedures in advance. This approach led to better outcomes without causing additional harm to patients.
Using 3D printing for surgery planning has not been linked to any major negative effects. Instead, it appears to enhance surgical accuracy. For patients, this means a better chance of a successful surgery with fewer unexpected issues during the procedure. While any medical tool can carry risks, current research suggests that 3D printed models are generally safe for patients when used in surgery planning.12345Why are researchers excited about this trial?
Researchers are excited about using 3D printing alongside conventional imaging for hip surgery planning because it offers a more detailed and personalized approach. Unlike standard imaging methods like X-rays, CTs, and MRIs, which provide 2D or sectional views, 3D printing creates a tangible model of the patient's hip. This allows surgeons to visualize and plan the procedure more accurately, potentially improving surgical outcomes. By having a physical model, surgeons can better anticipate challenges and tailor their surgical approach to each individual's unique anatomy.
What evidence suggests that 3D printing is effective for hip surgery planning?
This trial will compare the use of 3D printed models combined with conventional imaging to conventional imaging alone for hip surgery planning. Research has shown that using a 3D printed model alongside regular imaging can enhance hip surgery planning. Studies have found that these models provide surgeons with a clearer understanding of the hip, potentially leading to more accurate surgeries. Specifically, 3D models have changed how surgeons plan for femoroacetabular impingement, a condition where hip bones rub together. This could result in fewer complications and better outcomes for patients. Overall, early evidence suggests that adding a 3D model to traditional imaging offers a clearer view, which might improve surgical success.25678

What Are the Treatments Tested in This Trial?
Interventions
- 3D Print + Conventional imaging
- Conventional imaging
Trial Overview
The study compares two approaches in planning hip preservation surgery: one group uses standard imaging techniques like X-ray and MRI only; the other group gets a personalized 3D printed model based on these images as well. Patients will be randomly assigned to either group.
How Is the Trial Designed?

Treatment groups
Experimental Treatment
Patients in this group allocation will receive conventional preoperative imaging (X-ray, CT, and MRI) only for the use of pre-operative and intra-operative planning for their hip arthroscopy (FAI) procedure.
Patients in this group allocation will receive a 3D reconstruction of their hip in addition to conventional preoperative imaging (X-ray, CT, and MRI) only for the use of pre-operative and intra-operative planning for their hip arthroscopy (FAI) procedure.
