NCT07571798

Brief Summary

The goal of this clinical trial is to learn about the surgical techniques of percutaneous sacroiliac screw fixation both the two-view fluoroscopic technique (sacral inlet and outlet views) and the standard three-view fluoroscopic technique (lateral, sacral inlet, and sacral outlet views). The main questions it aims to answer is:

  • Is there any difference of the operative time, intraoperative radiation exposure time, screw malposition rate, and postoperative neurological complication rate for percutaneous pelvic screw fixation between two techniques? Researchers will compare two surgical techniques of percutaneous sacroiliac screw fixation in high energy posterior pelvic ring injured patients. Participants will:
  • Be examined neurological status carefully before and after the operation
  • Get both preoperative and postoperative CT scan
  • Undergo the percutaneous sacroiliac screw(s) fixation with or without anterior plating fixation

Outcome Measures

Primary Outcomes (1)

  • Operative time

    Operative time in minutes that takes for insertion of guide pin of cannulated SI screw; From the time of skin incision to the final acceptable positioning of the guide pin (prior to screw insertion)

    perioperative record

Secondary Outcomes (3)

  • Radiation Exposure Time

    Perioperative record

  • Neurological complications by physical examinations and symptoms

    Immediate postoperative to two months after operation

  • Screw malposition

    Two months after operation, Postoperative CT scan will be evaluated for screw position.

Study Arms (2)

Percutaneous SI screw insertion using two fluoroscopic views

ACTIVE COMPARATOR

Patients with posterior pelvic ring or sacral injuries resulting from high-energy trauma who required the sacroiliac screw fixation. Surgeon will insert the SI screw percutaneously using sacral inlet and sacral outlet fluoroscopic views

Procedure: Percutaneous sacroiliac screw fixation using two or three fluoroscopic views

Percutaneous SI screw insertion using three fluoroscopic views

ACTIVE COMPARATOR

Patients with posterior pelvic ring or sacral injuries resulting from high-energy trauma who required the sacroiliac screw fixation. Surgeon will insert the SI screw percutaneously using lateral, sacral inlet and sacral outlet fluoroscopic views

Procedure: Percutaneous sacroiliac screw fixation using two or three fluoroscopic views

Interventions

Surgeon will insert the SI screw percutaneously using sacral inlet, sacral outlet fluoroscopic views with or without lateral sacral view

Percutaneous SI screw insertion using three fluoroscopic viewsPercutaneous SI screw insertion using two fluoroscopic views

Eligibility Criteria

Age20 Years - 60 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64)

You may qualify if:

  • Patients with traumatic posterior pelvic ring or sacral fractures indicated percutaneous screw fixation.
  • Patients who are fully conscious, possess decision-making capacity, and can provide informed consent.

You may not qualify if:

  • Presence of severe sacral dysmorphism (sacral dysmorphic score \> 70 and absence of osseous corridor)
  • Concomitant diagnosis of osteoporosis or age more than 60 years
  • Age under 20 years or evidence of skeletal immaturity
  • Pregnancy
  • Highly comminuted sacral fractures precluding accurate intraoperative assessment of the screw trajectory
  • Pre-existing lumbosacral neurological deficits prior to surgery
  • Withdrawal Criteria:
  • Intraoperative necessity to convert to an alternative surgical method (e.g., inability to safely proceed with percutaneous fixation).
  • Absence of postoperative computed tomography (CT) scan
  • Loss to follow-up within 2 months postoperatively
