Pelvic incidence (PI) is a key morphological parameter that reflects the relation between the sacrum and iliac wings. It is well accepted that PI remains constant after reaching maturity. However, recent studies indicated that PI might be altered after lumbosacral fusion. Additionally, it remains uncertain on the long-term influence of long fusion to pelvis with S2-alar-iliac screw on PI in patients with adult spinal deformity (ASD). ⋯ Our study showed that PI decreased in more than half of ASD patients immediately after spinal surgery using S2AI screws. Approximately 48% of them were able to recover during the 2-year follow-up. Lower pre-op PI, post-op PI and PT were found to be strongly associated with the return of PI. Thus, these current findings indicated that patients with a high PI at pre-operation should not be over-corrected to avoid PI-LL mismatch postoperatively.

Transcranial electrical stimulation motor-evoked potentials (TES-MEPs) are an intraoperative neurophysiologic monitoring method that reduces adverse outcomes in various spine surgeries. Although spine surgeons rarely use TES-MEPs for simple lumbar decompression surgery, we herein firstly report the efficacy of TES-MEPs for lumbar spinal canal stenosis with asymptomatic coexisting cervical canal stenosis. ⋯ While TES-MEPs can be used to prevent neurological deficits in lumbar spine surgery, it can also be used to indirectly monitor other spinal lesions. Based on our experience, we recommend using TES-MEPs even in lumbar spine surgery.

Is conservative treatment a good choice for pediatric intervertebral disc calcification in children?
Paediatric intervertebral disc calcification (PIDC) is a rare disease, and its aetiology remains unknown. This study aimed to analyse the characteristics and clinical outcomes of patients with PIDC. ⋯ IV.

Review Meta Analysis
Preoperative epidural steroid injections do not increase the risk of postoperative infection in patients undergoing lumbar decompression or fusion: a systematic review and meta-analysis.
Epidural corticosteroid injections (ESI) are a mainstay of nonoperative treatment for patients with lumbar spine pathology. Recent literature evaluating infection risk following ESI after elective orthopedic surgery has produced conflicting evidence. Our primary objective was to review the literature and provide a larger meta-analysis analyzing the temporal effects of steroid injections on the risk of infection following lumbar spine surgery. ⋯ II.
