Abstract:
Objective:To investigate the feasibility and clinical efficacy of percutaneous screw fixation for acetabular anterior column fracture with laser-assisted axial fluoroscopy.Methods:Data of 20 patients (22 sided) with acetabular anterior column fracture treated by percutaneous screw fixation with laser-assisted axial fluoroscopy from January 2017 to December 2018 were retrospectively analyzed. There were 11 males and 9 females with an average of 42.1±3.2 years (range, 24-68 years). There were 7 cases of unilateral acetabular anterior column fracture, 2 cases of bilateral acetabular anterior column fracture (4 sides), 7 cases of anterior column with ipsilateral sacral fracture, and 4 cases of anterior column with sacroiliac joint injury. There were 3 hips of Area I, 6 Area II, 13 Area III of acetabular anterior column fractures according to Nakatani partition. The time from injury to surgery was 5 days (range, 3-11 days). All patients with acetabular anterior column fractures were fixed by percutaneous screw fixation with laser-assisted axial fluoroscopy, and patients with sacral fracture or sacroiliac joint injury were fixed by percutaneous sacroiliac screws with Starr frame-assisted reduction. The time of operation, the number of intraoperative fluoroscopy and the amount of intraoperative bleeding were recorded. Matta scoring criteria were used to assess fracture reduction quality, and hip function was assessed at the last follow-up according to the modified Merle D' Aubigné and Postel scoring system.Results:The average operative time was 22±10 min (range, 20-40 min) with an average times of intraoperative fluoroscopy of 30±8 times (range, 21-45 times), and the amount of intraoperative blood loss was 20±5 ml (range, 10-40 ml). 20 patients were followed up after operation for a period of 14±3.1 months (range, 12-18 months). The quality of postoperative fracture reduction was assessed according to the Matta acetabular fracture reduction criteria: anatomical reduction in 18 hips, satisfactory reduction in 2 hips, unsatisfactory reduction in 2 hips, with an excellent and good rate of 91% (20/22). The fracture healing time was 13±2.2 weeks (range, 11-16 weeks). At the lastest follow-up, hip function was assessed according to the modified Merle D' Aubigné and Postel scoring system: excellent 18, good 3, fair 1, and the satisfactory rate was 95%(21/22). No major neurological, vascular injury, wound infection and ectopic ossification were found during follow-up.Conclusion:Using laser-assisted axial fluoroscopy percutaneous screw to treat acetabular anterior column fracture, the operation is simple. And there is low risk to damage important blood vessels and nerves. This method can shorten the operation time of acetabular anterior column fracture, reduce the amount of blood loss during the operation, and the outcome is satisfactory.
