Early Partial Weight-bearing May Improve Functional Recovery Without Increasing Complications Despite This Potential, Limited Randomized Studies Have Evaluated Early Weight-bearing After Pelvic Fixation Surgeries

Inclusion criteria

• Age ≥ 18 to 55 years
• Traumatic fractures indicated for pelvic fixation.
• All Types B after stable anterior and / or posterior fixation.
• Type C, Stable fixation:

Posterior fixation by triangular osteosynthesis. oTrans-iliac trans-sacral screw fixation or Trans iliac plate or posterior infex combined with anterior fixation.

• Excellent to good quality of fracture reduction by Matta and Tornetta radiological assessment.

Exclusion criteria

• Associated lower extremity fractures that independently restrict or contraindicate weight-bearing activities.
• Bilateral unstable after fixation pelvic ring disruption.
• Patients with associated spinal cord injury, as neurological deficits may alter gait, functional recovery, and weight-bearing capacity, thereby affecting the validity and generalizability of the outcome measures.
• Current history of acute systemic infection, active Bone inflammatory disease, (e.g., osteomyelitis, chronic non-bacterial osteitis), or malignancy, which may compromise the healing process, confound clinical outcomes, or pose additional medical risks during rehabilitation.
• Uncontrolled Diabetes
• Cancer
• Active infection
• Morbid obesity (BMI > 40)
• Alcohol use disorder (AUD). Alcohol abuse as defined by the National Institute on Alcohol Abuse and Alcoholism: "Drinking at Low Risk for Developing Alcohol Use Disorder: For women, low-risk drinking is defined as no more than 3 drinks on any single day and no more than 7 drinks per week. For men, it is defined as no more than 4 drinks on any single day and no more than 14 drinks per week. NIAAA research shows that only about 2 in 100 people who drink within these limits have AUD".
• Claustrophobia
• Pregnant woman
• Inability to follow study protocol (e.g., lack of ability to attend visits or comprehend instructions)
• Any psychiatric illness that would prevent comprehension of the details and nature of the study and interfere with follow-up clinical visits
• Any clinical finding that would place the patient at health risk, impact the study, or affect the completion of the study
