A Comparison of Non-vascularized Bone Grafting and Internal Fixation in the Treatment of Unstable Scaphoid Waist Nonunion.

: When nonunion of scaphoid waist is treated with non-vascularized bone grafting with internal fixation, bony union would be affected not only type of bone graft but also fixation method. Thus, we attempted to investigate whether the bony union depends on how surgeons combine bone grafting and internal fixation. : We treated 38 consecutive patients with unstable nonunion of scaphoid waist.

Efficacy of Postural Reduction of Vertebral Compression Fracture with Extension Lateral Radiograph Before Vertebroplasty.

Objective: This retrospective comparative study aimed to evaluate the efficacy of postural reduction of vertebral compression fracture (VCF) using the hyperextension posture before vertebroplasty (VP).

Methods: Sixty-five consecutive patients who underwent VP were retrospectively reviewed. Thirty patients who underwent passive expansion of compression fracture before VP (postural reduction vertebroplasty [PRV] group) were compared with 35 patients who underwent in situ vertebroplasty (ISV group).
