Current concepts in spondylopelvic dissociation.

Area of Science:

• Orthopedic Surgery
• Trauma Management
• Pelvic Reconstruction

Background:

• Spondylopelvic dissociation is a rare, high-energy pelvic injury often resulting from axial overloading.
• Initial management follows Advanced Trauma Life Support (ATLS) protocols, emphasizing physical examination and high suspicion for diagnosis.
• Radicular neurological deficits are common and require documentation.

Purpose of the Study:

• To review the anatomy, biomechanics, and classification of spondylopelvic dissociation.
• To discuss surgical stabilization, conservative treatment options, and the timing of intervention.
• To emphasize reduction techniques and posterior surgical stabilization for complex pelvic disruptions.

Main Methods:

• Review of relevant literature on spondylopelvic dissociation.
• Discussion of diagnostic criteria, including physical exam, radiographic views, and CT scans.
• Emphasis on surgical techniques for reduction and posterior stabilization, including the use of S2/S3 screws and transitional rods for residual kyphosis.

Main Results:

• Infection and implant failure are the most common complications following surgical treatment.
• Posterior stabilization is recognized as essential for managing pelvic disruptions.
• Circumferential restoration using bilateral lumbopelvic and anterior fixation offers enhanced stability and alignment.

Conclusions:

• Prompt diagnosis and appropriate management are critical for spondylopelvic dissociation.
• Posterior surgical stabilization is a cornerstone of treatment for these complex pelvic injuries.
• Combined anterior and posterior fixation may improve outcomes by ensuring pelvic ring stability.
