To evaluate whether a relationship exists between patient-based scoring systems and the activity level of patients with low back pain (LBP) by using wearable activity trackers, and to determine whether activity level was affected by patient factors. ⋯ Some domains of the questionnaires were correlated with activity level, but others were not. Additionally, the activity level of patients with LBP was affected by sex, BMI, LBP, and skeletal muscle mass index. These slides can be retrieved under Electronic Supplementary Material.

To investigate the effects of cervical decompression operation on cardiac autonomic regulation and its relationship to recovery of somatic neurological function in cervical spondylotic myelopathy (CSM) patients. ⋯ Cervical decompression operation could improve both somatic neurological function and cardiac autonomic regulation in CSM patients, and achieved JOA score was significantly positively correlated with improvement in HRV and cardiac parasympathetic activity.

To present a novel technique for anterior instrumentation and reconstruction with PVCR for treatment of severe neglected congenital kyphosis through posterior approach. ⋯ Addition of anterior instrumentation to PVCR allows controlled gradual correction and more biomechanical stability. This technique should be preserved for high degrees of sagittal plane deformities. These slides can be retrieved under Electronic Supplementary Material.

Intraforaminal ligaments (IFL) in lumbar neural foramina (NF) and their relation to the lumbar spinal nerves (SN) are addressed. ⋯ Manual dissection seems to be inappropriate for a detailed study of the IFL. The lateral and intermedial compartments being free of the SN may transmit power and protect the SN, while the thin medial IFL may lead the SN passing the NF under physiological conditions. We conclude from the close topographical relation that the IFL may be relevant in foraminal stenosis. Any herniation in the NF presses IFL to the SN. Therefore, we think the IFL themselves could cause neurogenic claudication in case of their non-physiological turnover. Visualisation of IFL seems to be possible by using MRI.
