Early Internal Fixation Versus NonOperative Care With Early Rehabilitation for LC1 Fragility Fractures of the Pelvis

Early internal fixation of the LC1 fragility fracture of the pelvis will be defined as percutaneous anterior and/or posterior pelvic internal fixation with cannulated screw(s), medullary implant(s), or sacroiliac joint fusion device(s). The implant number, design, diameter, thread type (fully-threaded or partially-threaded), sacral segment (S1, S2, S3, or any combination there of), length, trajectory including sacroiliac or transsacral-transiliac, application with or without a washer, and ingrowth or ongrowth surface designs will be at the discretion of the treating surgeon.

Nonoperative care with early rehabilitation will consist of nonoperative treatment of the pelvis fracture, including early consultation of the physical therapist, physiotherapist, or local equivalent rehabilitation provider at the time of randomization for a first attempt at mobilization of the patient within 24 hours of randomization. Patients who are unable to ambulate with assistance after five or more days of attempted mobilization by rehabilitation providers may be considered for delayed internal fixation treatment at the discretion of the patient and the treating surgeon. Delayed internal fixation after five or more days of attempted mobilization by rehabilitation providers will not be considered a treatment crossover event.
