Transforaminal full-endoscopic lumbar surgery is widely accepted as a method of treating lumbar conditions, such as disc herniation, spinal stenosis, and lumbar foraminal stenosis (LFS). This minimally invasive approach, often performed under local anesthesia, is ideal for older patients and those with significant comorbidities. Full-endoscopic lumbar foraminotomy (FELF) has shown high success rates and notable symptom relief for LFS. However, complications including postoperative dysesthesia, dural tears, restenosis, and scoliosis progression, especially at L5–S1 due to extensive facet joint resection, remain challenges. In such cases, lumbar fusion may be more appropriate. A unique anatomical feature, the "lateral kissing spine," is characterized by contact between the L5 transverse process and the sacral ala. This feature appears to mitigate scoliosis progression, regardless of the preoperative Cobb angle or bone resection extent during FELF. We report two L5–S1 foraminal stenosis cases treated with FELF under local anesthesia: one with a lateral kissing spine, showing no scoliosis progression, and another without it, demonstrating significant progression. A review of 11 additional cases supports the protective role of the lateral kissing spine against scoliosis, even in cases with severe preoperative Cobb angles. This study reviews the complications of FELF, focusing on scoliosis progression, and proposes indications for FELF, highlighting the importance of the lateral kissing spine in surgical decision-making.

In the 2 decades or so since full-endoscopic spine surgery (FESS) was introduced, the procedure has advanced considerably. There are 2 major approaches of FESS, transforaminal (TF) and interlaminar. In this review article, we discuss the key strengths and merits of TF-FESS based on a literature search. First, the minimal invasiveness of the procedure allows for early return to work. Second, minimal invasiveness of the back muscles enables athletes to make a faster return to their previous competitive level. Third, the ability to perform TF-FESS under local anesthesia means it is suitable even in the elderly with poor general health.

Introduction: The purpose of this study was to clarify the relationship between the available service information on small-scale multifunctional in-home nursing care (KANTAKI) and its operational status via text mining.Methods: We obtained nationwide textual information on KANTAKI from the Nursing Care Service Information Disclosure System and the Ministry of Health, Labour, and Welfare, and analyzed the characteristics of the word usage using KH Coder. The number of users and employees and the implementation of services were compared among the facilities that used terms relating to medical dependency and end-of-life care, which are KANTAKI characteristics, and with other facilities.Results: The facilities that used terms relating to medical dependency and end-of-life care showed significantly more users requiring nursing care level 5 and more full-time nursing staff than those not using such terms. Moreover, regarding service provision, the rate of procedures was significantly higher in 11 of 12 items, except for stoma.Conclusion: The facilities that use terms relating to medical dependency and end-of-life care in their information have more users and provide a greater variety of services. In the future, educational support is required to enable facility managers to understand the services and translate them into their work.
