Pelvic Fracture Fixation
Pelvic Fracture Fixation
Pelvic Fracture Fixation is a critical surgical procedure used to stabilize the pelvic ring, typically following high-impact trauma such as motor vehicle accidents or significant falls. Because the pelvis protects major internal organs and a complex network of blood vessels, stabilizing these fractures is often a life-saving measure to control internal bleeding and restore structural integrity.
When You Should Consider Pelvic Fracture Fixation
Unstable Pelvic Ring: Injuries where the structural "circle" of the pelvis is broken in two or more places, making it unable to support the weight of the body.
Open Book Fractures: A severe injury where the front of the pelvis (pubic symphysis) is pulled apart, leading to a significant risk of internal hemorrhage.
Vertical Shear Fractures: When one side of the pelvis is pushed upward, often after a fall from a height, requiring mechanical realignment.
Persistent Pain and Malalignment: Fractures that have not healed correctly (malunion) or cause chronic instability and gait issues.
Emergency Hemorrhage Control: Use of an external frame as a rapid intervention to decrease pelvic volume and stop life-threatening bleeding.
Methods of Pelvic Fracture Fixation
External Fixation: A rapid "damage control" method using metal pins drilled into the hip bones and connected to an external carbon fiber frame.
Anterior ORIF: Placing surgical plates and screws across the front of the pelvis, such as the pubic symphysis.
Posterior ORIF: Internal stabilization of the back of the pelvic ring using heavy-duty plates for sacroiliac (SI) joint injuries.
Percutaneous Cannulated Screws: A minimally invasive technique where long screws are inserted through tiny "stab" incisions into the sacrum under real-time X-ray guidance.
Pelvic C-Clamp: An emergency external device used specifically to compress the back of the pelvis in cases of severe posterior instability and bleeding.
How Pelvic Fracture Fixation Is Performed
Resuscitation and Alignment: In emergencies, the patient is stabilized with a pelvic binder or sheet to control bleeding before entering the operating room.
Reduction: For internal surgery, the surgeon makes an incision to manually pull and maneuver the pelvic bones back into their anatomically correct "ring" shape.
Plate and Screw Fixation: High-strength titanium or stainless steel plates are contoured to the curve of the pelvic bone and secured with multiple screws.
Iliosacral Screw Insertion: For posterior injuries, long screws are driven from the side of the hip bone directly into the sacrum to lock the back of the pelvis.
Fluoroscopic Verification: Throughout the procedure, the surgeon uses a C-arm (mobile X-ray) to ensure hardware is not impinging on nerves or blood vessels.
Wound Closure: Given the complexity of pelvic anatomy, deep sutures and sometimes surgical drains are used to prevent fluid or blood buildup.
Pre-Procedure Preparation
Emergency stabilization using a pelvic binder to minimize internal volume and promote blood clotting.
Diagnostic imaging including AP, inlet, and outlet X-rays, alongside CT scans with 3D reconstruction to map the fracture.
Aggressive resuscitation with IV fluids and blood transfusions to achieve hemodynamic stability.
Detailed neurological and urological exams to document any nerve or bladder damage existing prior to surgery.
Tests Before Pelvic Fracture Fixation
CT Scan with 3D Reconstruction: The gold standard for understanding complex pelvic displacement and planning hardware placement.
Retrograde Cystourethrogram: A specialized imaging test to check for injuries to the bladder or urethra, which are common with pelvic breaks.
Angiography: Occasionally performed if there is persistent bleeding to identify and "plug" (embolize) damaged arteries.
Blood Panels: Frequent monitoring of hemoglobin and hematocrit levels due to the high risk of blood loss associated with pelvic trauma.
Life After Pelvic Fracture Fixation
Hospital stays are often extended, ranging from several days to several weeks depending on other trauma.
This is the most restrictive recovery phase; patients are typically Non-Weight-Bearing or "toe-touch" only for 6 to 12 weeks to protect the hardware.
Mandatory use of blood thinners (anticoagulants) for 2–6 weeks is required to prevent life-threatening blood clots (DVT).
Many patients require a transition to a specialized rehabilitation facility to regain the ability to sit, stand, and eventually walk.
Full biological union of the bone typically occurs within 3 to 4 months, but full strength recovery can take up to a year.
Benefits of Pelvic Fracture Fixation
Provides immediate mechanical stability to the core of the body, allowing for earlier mobilization and seated upright positions.
Dramatically reduces the risk of death from internal hemorrhage by "closing" the pelvic space.
Restores the anatomical symmetry of the hips, preventing long-term leg-length discrepancies and chronic back pain.
Protects the long-term function of the pelvic organs by providing a stable "house" for the bladder, rectum, and reproductive systems.
