Abstract:
Objective:To investigate the clinical effect of "ladder reduction method" in the treatment of iliac fracture combined anterior dislocation of sacroiliac joint.Methods:The retrospective analysis was performed on 10 cases of iliac fracture combined anterior sacroiliac joint dislocation admitted to the Affiliated Hospital of Yunnan University from February 2010 to January 2022, among which 5 cases were males and 5 cases were females, aged ranging from 22 to 52 years, with an average age of 38.8 years. All patients were injured in car accidents including 5 cases of C1.2, 3 cases of C2, and 2 cases of C3 fractures according to Tile classification. All patients were treated with the "ladder reduction method" with plate and screw fixation. In the first step, 1-2 Schanz pins were inserted into the iliac crest to control the ilium, and the Schanz pins were appropriately pulled laterally; in the second step, the periosteal stripper was used to pry the reduction between the sacrum and ilium; in the third step, for the patients who still could not be reduced, a 2.5 mm diameter Kirschner wire was placed on the sacrum close to the iliac crest, and a periosteal stripper was inserted between the sacrum and iliac crest, with its tip against the Kirkner wire, and the iliac crest as the fulcrum for pry pulling to separate the two. In the fourth step, the pry was maintained, and then another 2.5 mm diameter Kirschner wire was placed on the sacrum close to the internal margin of the iliac bone. The periosteal stripper was continued to pry between the sacrum and the iliac bone, and the operation was repeated. At the same time, the anterior dislocation of the sacroiliac joint was reduced with traction of the lower limb. Postoperatively, the quality of reduction was evaluated by the Matta score, and the degree of functional recovery after pelvic fracture was evaluated by the Majeed score.Results:Four patients completed the reduction through the first and second steps, and 6 cases of refractory sacroiliac joint anterior dislocation were successfully reduced through the first to fourth steps. The fracture reduction time of 6 patients with refractory anterior sacroiliac joint dislocation was 39.67±3.09 min (range, 35-44 min), with intraoperative blood loss of 300.00±141.42 ml (range, 150-600 ml); in the other 4 cases, the fracture reduction time was 36.75±4.38 min (range, 30-42 min), and the intraoperative blood loss was 225.00±44.30 ml (range, 200-300 ml). All 10 patients were followed up for 12.9±3.7 months (range, 9-20 months). The anterior and posterior pelvic ring fractures were healed in all patients, and the fracture healing time was 12.77±1.62 weeks (range, 10.71-15.28 weeks). At the last follow-up, Matta evaluation was excellent in 5 cases, good in 1 case, and excellent in the other 4 cases. The Majeed scores of 6 cases were 86.50±6.08 points (range, 74-92 points), of which 5 cases were excellent and 1 case was good. The other 4 cases were 81.5±9.39 scores (range, 71-94), of which 2 were excellent and 2 were good.Conclusion:The "ladder reduction method" is a safe, effective and easy-to-operate method for the treatment of iliac fracture combined anterior dislocation of the sacroiliac joint, especially for refractory anterior dislocation of the sacroiliac joint, which can still obtain satisfactory curative effects.
