Study Details

Brief summary:

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.

Eligibility Criteria

Eligibility Criteria

Sex: All

Age: 18+

Healthy Volunteers: Not accepted

Inclusion Criteria:

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

Exclusion Criteria:

1. Patients who have undergone an external (hindquarter amputated), or an isolated type III internal hemipelvectomy.
2. Previous surgery or significant injury to either hip (prospective patients only)
3. 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)
4. Pregnant women or women nursing an infant
5. 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.
6. 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.

Allocation

Non randomized

Intervention Model

Single group

Primary purpose

Supportive Care

Interventions and Outcome Measures

Arms

experimental: Supportive care (walking function test, X-ray)

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

no intervention: Retrospective Group

1. Acquisition of pre- and post-operative MRI data of the pelvic region (when available) collected previously as part of standard clinical care
2. Acquisition of pre-operative CT data of the pelvic region (when available) collected previously as part of standard clinical care
3. Acquisition of Physical Therapy Assessment data collected previously by a physical therapist and/or physical therapist assistant under protocol PA12-1046

Interventions

Functional Assessment

Undergo walking function assessment with optical motion capture

X-Ray Imaging

Undergo bi-plane dynamic X-ray imaging

Primary outcome measure

  • 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 ]
