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
