Summary
This study shows that using two threaded compression rods effectively stabilizes sacroiliac joint dislocations and fractures (Malgaigne pattern). This method allows for early patient mobilization, reducing complications associated with prolonged bed rest.
Area of Science:
- Orthopedic surgery
- Trauma surgery
Background:
- Sacroiliac joint dislocations and fractures (Malgaigne pattern) present complex stabilization challenges.
- Traditional methods may lead to complications from prolonged immobilization.
Purpose of the Study:
- To evaluate the efficacy and safety of using two threaded compression rods for treating Malgaigne pattern pelvic injuries.
- To assess implant durability and patient outcomes, including pain and neurological function.
Main Methods:
- Eleven patients with sacroiliac dislocation/fracture underwent reduction and stabilization with two threaded compression rods.
- Rods were inserted from the posterior iliac wing superficial to the sacrum, compressing the pelvic ring.
- Follow-up averaged 26.1 months.
Main Results:
- All eleven cases achieved successful reduction and stable fixation without implant failure or displacement.
- Two patients reported mild residual lower back pain; one required implant removal without pain relief.
- One patient experienced worsening of a preoperative peroneal nerve palsy.
Conclusions:
- The described technique using two threaded compression rods is a safe and effective method for stabilizing Malgaigne pattern pelvic injuries.
- Stable fixation allows for early mobilization, potentially preventing complications of bed rest.
- This approach offers a reliable surgical option for complex pelvic ring disruptions.
