Pre- and postoperative radiological studies of case 1.
. 
Preoperative computed tomography (CT) reveals a markedly displaced vertebral body fracture at the C6 level by hyperextension injury (A). Postoperative cervical (B) and thoracic (C) X-rays reveal the operative construct of O-Th10 posterior lateral fixation with occipital bone plate and pedicle screws. The follow-up CT at 1 year after the operation (D) showed bony fusion between the fractured ends at the C6 level.

T1 levels for cervical ossification of the posterior longitudinal ligament (OPLL) at another institute more than 15 years earlier. Computed tomography (CT) revealed a markedly displaced vertebral body fracture at the C6 level, presumably due to hyperextension injury (Fig. 1A). The patient underwent external fixation using a halo vest as the primary treatment and received in situ posterior fixation from the occiput to the T10 level using occipital bone plate and pedicle screws 1 week later (Fig. 1B, C). The follow-up CT at the 1-year mark revealed bony fusion bridging the dislocated vertebral fracture (Fig. 1D).

Pre- and postoperative radiological studies of case 2.
. 
Preoperative computed tomography (CT) reveals chance fracture at the L1 level with severe translation (A, B). Postoperative lumber X-ray (C) reveals the operative construct of the caudal part of posterior fixation with pedicle screws and S2 alar iliac screws demonstrating slight reduction of the fracture. The follow-up CT at 1 year postoperatively reveals bony fusion between the fractured ends (D, E).

C2 to the T12 levels for OPLL and compression fracture of the Th2 vertebral body 2 years before. CT revealed a dislocation fracture at the L1 vertebral body (Fig. 2A, B). S2 levels using pedicle screws and S2 alar iliac screws (Fig. 2C). She was relieved from pain in the right leg postoperatively. The follow-up CT after the operation revealed bone synthesis between the fractured ends along the anterior longitude ligament at 6 months and almost complete bony fusion at 1 year postoperatively (Fig. 2D, E).

Pre- and postoperative radiological studies of case 3.
. 
Preoperative computed tomography reveals unstable C7 transverse fracture with listhesis (A). Postoperative cervical A-P X-ray reveals the fusion levels (B). The follow-up CT at 1 year postoperatively reveals bony fusion between the fractured ends along the anterior longitude ligament (C).

A 78-year-old male had a dislocation fracture at the C7-T1 levels after falling down the stairs (Fig. 3A). Th2 levels was performed (Fig. 3B). The follow-up CT at the 1-year mark revealed solid bony fusion between severely dislocated vertebral bodies (Fig. 3C).
