Abstract

Background: Pelvic fractures are often associated with life-threatening damage and mechanical instability. Surgical therapy is a prior choice. To minimize surgical invasion and risk, bilateral screws combined with curved rod were applied to stabilize posterior pelvic ring. This study was aim to explore the clinical effect of this procedure.

Methods: From January 2018 to January 2022, 27 patients with posterior pelvic fracture were included retrospectively. There were 12 males and 15 females with an average age of 56.3 ± 14.2 years. The prognosis of pelvis was evaluated by Matta and Majeed scores. Relevant clinical evaluation indications include the time of fracture healing, limb function and complications.

Results: The average follow-up time was 14.2 ± 5.4 month. Matta scoring standard: excellent in 18 cases, good in 7 cases, the good rate was 92.6%. The average healing time was 8.4 months. The standard of Majeed score in 6 months after operation: excellent in 14 cases, good in 10 cases, the good rate was 88.8%. At the last follow-up, the functional recovery of the affected limb was satisfactory. No deep infection occurred after operation. The neurological symptoms of patients with caudal sacral nerve injury were recovered 6 months after operation.

Conclusion: The results indicated that screw-rod system is a safe technique. Minimally invasive technology reduced frequency of fluoroscopy. It provides a simple and safety method for posterior pelvic fracture.

Keywords: Pelvic fracture; Screw-rod system; Unstable pelvic ring.
