RESUMO
Background Tibia fracture is a common indication for operative intervention in orthopedics. Usage of Intramedullary nailing provides a minimally invasive technique with good results. Positioning, operative time, and radiation exposure are major points in such cases. This study described the semi-extended lateral parapatellar intramedullary technique as a technique that helps achieve and maintain reduction, simplifies nail insertion, and decreases fluoroscopy and operative time. Methodology This prospective case series study included nine patients with tibial shaft fractures operated at Royal Rehabilitation Center from April to October 2023 by intramedullary nailing and extra-articular lateral parapatellar insertion technique using the semi-extended knee position. Duration of surgery, intraoperative radiation exposure, and anterior knee pain score were assessed for all patients. Results The average duration of surgery was 63.78 ± 5.3 minutes, and the average intraoperative imaging was 94 (85-103). The average union time was 18 ±2 weeks. The mean Kujala score was 90.9% ± 2.3% six months after the surgery. All patients regained a comparable range of motion in their knees and ankles. One patient reported minimal pain at the pin site but did not require any analgesia. Conclusion The lateral parapatellar approach for tibial shaft fracture nailing has the advantage of reducing operative time, the number of intraoperative radiographs, and lower postoperative anterior knee pain. Additionally, this approach did not cause patellar instability.
