Outcomes of conservative therapy for PCFs are relatively good; however, some PCFs should be treated surgically to correct an initial kyphotic deformity or to prevent further neurological deterioration or a progressive deformity [
17]. Since the injury of PCFs is mainly the posterior osteoligamentous complex, reduction and stabilization with posterior instrumentation should be considered [
18]. When treating acute PCFs surgically, pedicle screw instrumentation, which extended one or two levels above and below the affected vertebra, seems to be a popular treatment [
19]. With a recent progress of spinal instrumentations, percutaneous pedicle screw fixation may have evolved as an alternative approach for PCFs [

20]. On the other hand, there are only a few reports of surgical treatment for chronic deformities due to PCFs, including combined anterior and posterior fusion surgery, transforaminal thoracic interbody fusion, and transpedicle wedge osteotomy and posterior fusion [

22]. Asymmetrical PSO, which was first reported in 2012 by Sathya et al. [
23], is not a novel technique; however, it seems to be rare rerated to a report of asymmetrical PSO for a chronic pediatric Chance fracture. Our patient’s spinal deformity was caused by a deformity of the fractured L2 vertebra, so we judged that short fusion with asymmetrical PSO was sufficient to correct the affected vertebra. Our osteotomy procedure included partial resection of the pedicle, vertebral body, and adjacent disc in an applied grade 4 osteotomy, according to the classification system of anatomically based spinal osteotomies proposed by Schwab et al. [
24]. In this case, we intended to fuse from T12 to L3 for the maintenance of spinal alignment after correction of scoliosis and kyphosis. The application of without fusion technique at L2/L3 fact joints and future removal of the spinal implants might be another option to preserve motion segment at L2/L3. However, we have removed posterior ligamentous complex at L2/L3 during the surgery and were afraid of the occurrence of distal junctional problem after removal of the implants.
