A screw view model of navigation guided minimal invasive percutaneous pelvic screws insertion for lateral compression pelvic ring injuries

Abstract

Rationale: The objective of the present study was to evaluate the accuracy, effectiveness, and safety of screw view model of navigation (SVMN) guided minimal invasive percutaneous pelvic screws (PPSs) insertion for lateral compression pelvic ring injuries (PRI). Patient concerns: A female patient experienced a high falling injury, and presented with pain, swelling, deformity, and movement limitation of the left hip for 3 hours. Diagnoses: She was diagnosed with pelvic fractures, left iliac fracture, left pubic branch fracture, left ischial branch fracture, and lumbar transverse process fracture. Interventions: We used a SVMN technique to guide PPSs insertion, including a percutaneous anterior inferior iliac spine screw, a percutaneous iliac screw (PIS), and a percutaneous sacroiliac screw (PSIS). Outcomes: In total, 3 PPSs were inserted and all were presented with excellent position postoperatively. The designing time of all screws was 11.7 minutes, the time of all guide needles insertion was 18.1 minutes, the time of all screws insertion was 32.8 minutes, blood loss was 21 mL, and the time of radiation exposure lasted 7.2 minutes. Moreover, surgical complications, including neurovascular compromise, wound infection, fracture nonunion, and screw loosening, were not observed during the 12 months follow up visit. Lessons: SVMN technique guided PPSs insertion is an effective and safety approach for the treatment of PRI in selected patients. Besides, it is necessary for surgeons to master the rationale of computer navigation, to familiar with the anatomy of pelvis and to select suitable patients.

Pelvic Ring Fractures: A Biomechanical Comparison of Sacral and Lumbopelvic Fixation Techniques

“…To mitigate this, recent literature has investigated several minimally invasive treatment approaches that have been found to be equally stable 5,8 . These treatments include the trans-iliac trans-sacral screw (TITS) 9 , the ilio-sacral (IS) screw 10,11 , the transiliac rod and screw fixation (TIF) procedure and lumbopelvic fixation (LP) 8 12, 13 14 . However, controversy remains on the advantages and disadvantages of these minimally invasive treatment options for unstable pelvic fractures.…”

“…To mitigate this, recent literature has investigated several minimally invasive treatment approaches that have been found to be equally stable [5,8]. These treatments include the trans-iliac-trans-sacral screw (TITS) [9], the ilio-sacral (IS) screw [10,11], the transiliac rod and screw fixation (TIF) procedure and lumbopelvic fixation (LP) [8,[12][13][14]. Several biomechanical studies have been conducted to assess the fixation techniques for fracture treatment.…”
