Abstract:
Objective:To evaluate our self-designed pubic symphysis orthotic compression anatomic plate (PSOCAP) in the treatment of fractures and dislocations around the pubic symphysis.Methods:A retrospective study was conducted to analyze the 16 patients with fracture or dislocation around the pubic symphysis who had been treated by our self-designed PSOCAP at Department of Traumatic Surgery, Center for Orthopaedic Surgery, The Third Hospital Affiliated to Southern Medical University from January 2021 to June 2022. There were 8 males and 8 females with an age of (41±19) years. According to the Tile classification for pelvic fractures, there were 3 cases of type B1, 2 cases of type B3, 1 case of type C1.2, 4 cases of type C1.3, 3 cases of type C2, and 3 cases of type C3. There were 8 cases of pubic symphysis separation and 8 fractures of the pubic ramus (2 ones at Nakatani zone Ⅰ and 6 ones at Nakatani zone Ⅱ). Time from injury to surgery was 16 (11, 53) days, ranging from 4 to 348 days. The fractures or dislocations around the pubic symphysis were exposed by the modified Stoppa approach, reduced with the assistance of PSOCAP and fixated with PSOCAP; the posterior pelvic ring was reduced and fixated by corresponding surgical methods. Recorded were the surgical time, intraoperative bleeding, postoperative quality of fracture reduction, surgical complications, and functional recovery at the last follow-up concerning the pelvic anterior ring.Results:Surgery went on successfully in the 16 patients. Their surgical time was (58±15) min, ranging from 40 to 90 min, and their intraoperative bleeding 85 (63, 150) mL, ranging from 50 to 250 mL. According to the Matta scoring, the fracture reduction was evaluated as excellent in 10 cases, as good in 3 cases and as fair in 3 cases. The (10±3)-month follow-up for the 16 patients revealed complete fracture union for all after (12±2) weeks. According to the Majeed scoring at the last follow-up, the pelvic function was evaluated as excellent in 5 cases, as good in 7 cases, and as fair in 4 cases. No such postoperative complications as fracture displacement or internal fixation failure occurred.Conclusion:Owing to the biplane and integrated structure, our self-designed PSOCAP can help reduce the fractures or dislocations around the pubic symphysis to achieve anatomical reduction and strong internal fixation, leading to good clinical efficacy.
