Abstract:
Objective:To evaluate the short-term efficacy of our modified anterior pelvic ring internal fixator(INFIX) in the treatment of anterior pelvic ring injuries.Methods:A retrospective study was conducted to analyze the clinical data from the 16 patients with pelvic anterior ring injury who had been treated with our modified INFIX at Department of Orthopaedics, The First Hospital Affiliated to Bengbu Medical University from June 2020 to June 2023. There were 9 males and 7 females with an age of (49.1±14.3) years. According to the AO/OTA classification, 10 cases were of type B2 and 6 cases of type C1. Their time from injury to surgery was (7.6±2.9) days. Fixation with our modified INFIX was as follows: Three pedicle screws were inserted into the anterior inferior iliac spine on one side and into the pubic symphysis on both sides. Next, a subcutaneous tunnel was created from the anterior inferior iliac spine incision toward the pubic symphysis, and connecting rods were inserted for fixation. The surgical incision length, intraoperative blood loss, surgical time, postoperative fracture reduction quality, fracture healing time, incidence of complications during follow-up, and pelvic functional recovery at the last follow-up were recorded in this cohort.Results:In this cohort, surgical incision length was (5.8±0.4) cm, intraoperative blood loss (75.4±11.9) mL, and surgical time (66.1±8.9) min. By the end of one week after surgery, the quality of fracture reduction was evaluated according to the Matta scoring criteria as excellent in 11 cases and as good in 5 cases. All patients were followed up for (17.4±3.1) months after surgery. The fractures got united in all the 16 patients after (11.2±1.2) weeks. At the last follow-up, the pelvic function recovery was evaluated according to the Majeed scoring system as excellent in 13 cases and as good in 3 cases, yielding a Majeed score of (90.1±4.2) points. During the follow-up period, no patient developed complications such as nerve injury, wound infection, or loosening, breakage or withdrawal of internal fixation devices.Conclusion:In the treatment of anterior pelvic ring injuries, our modified INFIX has the advantages of few complications, simple operation and minimal invasion, leading to good short-term efficacy.
