Cancellous bone was assumed to be linearly elastic followed by nonlinearly plastic such as crushable foam behavior. By the implementation of the characteristic of nonlinear bone plasticity into finite element analysis, more accurate effects of pedicle screw fixation-nut loosening on lumbar interbody fusion could be investigated.

A retrospective study was used to evaluate the treatment efficacy of combined anterior C2-C3 reduction and fusion and posterior compressive C2 pedicle screw fixation for the management of unstable hangman's fractures. The unstable hangman's fractures hold a large percentage of all hangman's fractures and indicated for surgeries. Anterior reduction and fusion is the preferred treatment to all the unstable hangman's fractures. Combined anterior C2-C3 reduction and fusion and posterior compressive C2 pedicle screw fixations can get better reduction and functional outcomes in some patients with severe unstable hangman's fractures.

The authors analyzed patients who underwent interbody fusion and pedicle screw fixation for L4–L5 spondylolisthesis with a healthy adjacent segment and followed up for more than 5 years. Results showed that maintaining postoperative L4–L5 segmental lordotic angle at about 20° or more is important for prevention of clinical ASD.

Many factors are capable of influencing health-related quality of life of adolescent idiopathic scoliosis patients. We found that residing in an urban versus rural environment does impact health-related quality of life. Clinicians must consider living environment when assessing health-related quality of life in adolescent idiopathic scoliosis patients to make the scores more objective and comparable.

The putative negative correlation between duration of symptoms and outcome after posterior lumbar interbody fusion for chronic low back pain was not observed across 7 outcome scores in our study. Symptom chronicity does not represent a poor prognostic indicator for chronic low back pain outcome after PLIF. PLIF should be considered irrespective of duration of symptoms.

A modified C2 translaminar screw fixation technique using bicortical screw fixation was developed and 120 adult axis specimens were measured to evaluate the applicability of this technique. Lamina thickness and spinous process height are the 2 limiting factors, but large percentages of C2 specimens are of sufficient size to safely accommodate a bicortical translaminar screw.
