Cervical pedicle screw placement using the "key slot technique": the feasibility and learning curve.
A retrospective study. ⋯ We performed CPS placement using the KS technique and with 90% correct position without clinical complications. After the learning curve, the incidence was 2.7%. This technique could be considered relatively concrete and safe modification of conventional technique with minimal bone loss.

Comparative StudyStand-alone anterior versus anteroposterior lumbar interbody single-level fusion after a mean follow-up of 41 months.
Prospective cohort study comparing evaluations of single-level anterior lumbar interbody fusion (ALIF) versus anteroposterior lumbar fusion (APLF). ⋯ Stand-alone ALIF leads to better clinical results than APLF, without differences in fusion rates after 41 months. Therefore, when a posterior approach is not needed for decompression or reposition, we suggest performing a stand-alone ALIF in cases with single-level DDD.
