Periarticular fractures around the knee joint are treated traditionally by locking plates which provide excellent stability but suppress callus formation. Far cortical locking (FCL) screws allow axial motion and enhance uniform callus formation. Our study aims to evaluate the outcomes of FCL screws in traditional locking plate in periarticular fractures of the knee.
Thirty patients with periarticular fractures of the knee joint were operated with locking plate using FCL screws. All patients were evaluated clinically and radiographically using X-rays at 6, 12, 24 weeks, 1 year and with CT scan at 12-weeks follow-up.
The average time for complete union was 20 weeks in tibial fractures and 24 weeks in femur fractures. Average time to full weight bearing ambulation was 4.8 ± 0.93 weeks. One patient had delayed union in which union was complete after 9 months.
This study shows that FCL screws in locking plates allow uniform callus formation and fracture union with minimal complication rates.
膝关节周围关节周围骨折传统上采用锁定钢板治疗，锁定钢板能提供出色的稳定性，但会抑制骨痂形成。远皮质锁定（FCL）螺钉允许轴向运动并促进均匀的骨痂形成。我们的研究旨在评估FCL螺钉在传统锁定钢板治疗膝关节周围骨折中的效果。
30例膝关节周围骨折患者采用带FCL螺钉的锁定钢板进行手术。所有患者在术后6周、12周、24周、1年时进行临床评估和X线片检查，并在12周随访时进行CT扫描。
胫骨骨折完全愈合的平均时间为20周，股骨骨折为24周。完全负重行走的平均时间为4.8±0.93周。1例患者出现延迟愈合，9个月后完全愈合。
本研究表明，锁定钢板中的FCL螺钉可促进均匀的骨痂形成和骨折愈合，并发症发生率极低。
