There has been a controversy in the surgical approach for delayed acetabular fracture. The objective of the present study is to investigate the feasibility, surgical techniques, safety, and efficacy of periacetabular osteotomy using the single lateral‐rectus approach (LRA) for the surgical treatment of delayed acetabular fracture. Methods The retrospective study included 22 patients (16 males and six females, with an average age of 45 years) with delayed acetabular fractures from June 2012 to June 2019. For all cases, periacetabular osteotomy was performed through the single LRA. Fracture classification, mechanism of injury, associated injury, time to surgery, operation time, intraoperative blood loss, and complications were recorded and analyzed. The quality of the reduction was assessed based on Matta radiographic criteria. Potential impact factors affecting the quality of reduction were analyzed. Functional outcome was evaluated at the final follow‐up according to a modified Mere D'Aubigne‐Postel scoring system for each patient. Results All patients were followed up for at least 12 months. The duration of surgery was 140 min on average (110–205 min) and the mean intraoperative blood loss was 1250 ml (500–2100 ml). According to Matta radiographic criteria, the accuracy of reduction was “anatomical” in seven patients, “imperfect” in 11 patients, and “poor” in four patients, with an excellent and good rate of 81.8%. The time to surgery in poor reduction group was significantly longer than anatomical or imperfect reduction group ( p 〈 0.05). All the acetabular fractures united after 8–12 weeks. The average modified Merle D'Aubigne‐Postel score evaluated at the final follow‐up was 14.6 (6–18), and the clinical outcomes were rated as excellent in six patients, good in 10 patients, fair in four patients, and poor in two patients, with an excellent and good rate of 72.7%. There were two cases of osteonecrosis of the femoral head (9%). No other complication was found for all cases. Conclusion The LRA is an effective and minimally invasive approach in the treatment of delayed acetabular fractures excluding posterior wall fracture and posterior dislocation.
