Patient-Specific Computational Walking Models in Improving Surgical and Rehabilitation Treatment in Patients With Pelvic Sarcomas

Official title

CPRIT: Optimizing Surgical and Rehabilitation Treatment of Pelvic Sarcomas Using Computational Models

Overview

This trial studies the development of patient-specific computational walking models to improve the surgical planning and rehabilitation treatment of patients with pelvic sarcomas. Every pelvis and pelvic sarcoma are different, and the orthopedic oncologist faces significant challenges when removing a tumor from the complex anatomy of the pelvis. These challenges make it difficult to achieve excellent oncological and functional outcomes together. Computational walking models may be used to predict the best combination of surgical methods and how to implement them to maximize each patient's post-surgery walking function.

Detailed description

PRIMARY OBJECTIVES:

I. To develop patient-specific computational walking models to predict the optimal combination of pelvic sarcoma surgical and rehabilitation decisions that will maximize each patient's post-surgery walking function.

II. To collect experimental movement and imaging data prospectively and retrospectively from individuals who have already received, or are going to receive, a type I or type II hemipelvectomy.

III. To use the data to develop computational modeling and simulation methodologies that can predict an individual patient's post-surgery walking function given pre-surgery movement and imaging data and the surgical decisions made by the surgeon.

OUTLINE:

Patients undergo walking function assessment using optical motion capture and bi-plane dynamic X-ray imaging pre- and post-hemipelvectomy.

Interventions

• Other Functional Assessment
  Undergo walking function assessment with optical motion capture
• Procedure X-Ray Imaging
  Undergo bi-plane dynamic X-ray imaging

Primary outcome measures

• To establish the patient-specific computational models to inform surgical decisions and design custom implants that maximize post-surgery function. [Time frame: through study completion, an average of 1 year]

Eligibility criteria

Inclusion criteria

• Patients who have received or are scheduled to receive an internal hemipelvectomy with or without reconstruction at UT MD Anderson Cancer Center.
• Patients who are 18 years of age and older

Exclusion criteria

• Patients who have undergone an external (hindquarter amputated), or an isolated type III internal hemipelvectomy.
• Previous surgery or significant injury to either hip (prospective patients only)
• Relevant surgery, procedure, injury, or condition in the last two years which may affect hip pain or general movement patterns on either side (prospective patients only)
• Pregnant women or women nursing an infant
• Persons with a pacemaker, hearing aid, aneurysm clips or artificial heart valves, and other forms of loose metal implants will be excluded from the study as assessed by a pre-MRI questionnaire administered by the MRI technician at the time of the scan.
• Radiological exclusion criteria (assessed after MR scan is conducted on the first visit, prior to DSX/CT radiation exposure): evidence on preliminary MRI of fracture, slipped capital femoral epiphysis (SCFE), masses, lesions, or other anomalies not consistent with an FAI diagnosis.

Criteria are shown verbatim from the registry (in English). Final eligibility is always assessed by the study center.
