Many patients retain sedentary lifestyles after lumbar surgery and incur increased risks of adverse health outcomes. The goal of this study was to assess patients' perspectives about postoperative physical activity. ⋯ Patients acknowledge short- and long-term benefits of physical activity for their spine and overall health; however, many are deterred from increasing activity by spine-related concerns. Interventions to improve physical activity should foster self-efficacy and self-direction and should be reinforced by members of the spine care team who are knowledgeable about prudent activities.

Inadequate anchoring of pedicle screws in vertebrae with poor bone quality is a major problem in spine surgery. The aim was to evaluate whether a modified thread in the area of the pedicle could significantly improve the pedicle screw fatigue strength. ⋯ Compared to a conventional pedicle screw, the use of a cortical threaded pedicle screw promises superior fatigue load in vertebrae with reduced bone quality.

Multicenter Study
Major complications in extreme lateral interbody fusion access: multicentric study by Italian S.O.L.A.S. group.
The eXtreme Lateral Interbody Fusion (XLIF) approach has gained increasing importance in the last decade. This multicentric retrospective cohort study aims to assess the incidence of major complications in XLIF procedures performed by experienced surgeons and any relationship between the years of experience in XLIF procedures and the surgeon's rate of severe complications. ⋯ XLIF revealed a safe and reliable surgical procedure, with a very low rate of major complications, when performed by an expert spine surgeon.

Multicenter Study
The prone transpsoas technique: preliminary radiographic results of a multicenter experience.
The lateral lumbar interbody fusion (LLIF) is a safe and effective technique to treat a vast range of lumbar disorders. However, the technique is also burdened by some problems. A new approach to the lateral lumbar interbody fusion was devised to solve or reduce some of the problems regarding the lateral approach. Its principal difference from the standard LLIF relies on positioning the patient in a prone decubitus, which might lead to an increase in the intradiscal lordosis. ⋯ The prone transpsoas technique is feasible and is associated with a significant gain of segmental lordosis and correction of spinopelvic alignment parameters.

The aim of this study was to identify factors that are independently associated with the 30-day unplanned readmission rate of patients who underwent elective spine surgery. ⋯ The present study showed that preoperative ASA physical status of ≥ 3, diagnosis of cancer, and transfusion of pRBC were associated with an increased 30-day unplanned readmission rate after elective spine surgery.
