In radiographic study, 101 patients with different etiology and 30 AS patients were included. After stratifying into different age groups, standing PI was significantly larger than supine PI in each age groups (P = 0.002, <0.001, and <0.001, respectively). In patients with degenerative diseases, PI was significantly larger on standing position than that on supine position. ΔPI showed no significant difference across etiologies. However, in AS patients, standing PI and supine PI revealed no significant difference (P = 0.528).

Mobile SI joint may be the cause of increased PI in the aging spine. The dynamic change of PI is etiology-independent if the SI joint was not fused. Older patients have greater position-related change of PI.Level of Evidence 4.

Observational, anatomical, cadaveric study.

We anatomically investigated the fibrous connection between the cervical nerves and the zygapophysial joint capsules.

Cervical spondylotic radiculopathy is caused by the compression of the cervical nerves as the static factor and head and neck movements as the dynamic factor. To understand the dynamic pathology of cervical spondylotic radiculopathy, the anatomic relationship between the cervical nerves and the zygapophysial joints needs to be investigated in detail.

In 11 cadavers, we dissected both sides from the C5 to C7. For macroscopic examination, we observed structures connecting the cervical nerves and the zygapophysial joints in 18 cervical nerves from 3 cadavers. LY450139 In 14 sides of 8 cadavers, we histologically analyzed the fibrous structures and their attachments.

Macroscopically, the fibrous band connected the cranial surface of the cervical nerve to the lateral and inferior aspects of the transverse process. In 4 of 18 nerves, the fibrous bands werEvidence N/A.
Some of the improvements in DH, FH, and SLL achieved intraoperatively during lateral lumbar interbody fusion surgery were lost by the postoperative 1-week follow-up. An intraoperative radiograph can predict radiographic and clinical outcomes of the 2-year follow-up. The difference between preoperative DH and intraoperative DH should be >4.18 mm.

This study evaluated incidence and risk factors associated with the development of facial pressure ulcers (FPU) in patients who underwent spine surgery in prone position. A total of 300 cases were studied. The incidence of FPU after prone spine surgery using head padded device >3 hours was 27.3%. Hypotension, higher temperature, prolonged operation time, and much crystalloid therapy were the independent risk factors.

The morphological features of the lateral atlantoaxial joints (LAJs) in patients with old type II odontoid fractures and atlantoaxial dislocation have not been fully analyzed. Our study found the changes in morphological features of the LAJs in some patients, and revealed the causes and consequences of the changes in morphological features of the LAJs.

Clinical case series.

To determine the effectiveness of the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) surgical risk calculator in the prediction of complications after anterior lumbar interbody fusion (ALIF).

Identifying at-risk patients may aid in the prevention of complications after spine procedures. The ACS NSQIP surgical risk calculator was developed to predict 30-day postoperative complications for a variety of operative procedures.

Medical records of patients undergoing ALIF at our institution from 2009-2019 were retrospectively reviewed. Demographic and comorbidity variables were entered into the ACS NSQIP surgical risk calculator to generate percentage predictions for complication incidence within 30 days postoperatively. The observed incidences of these complications were also abstracted from the medical record. The predictive ability of the ACS NSQIP surgical risk calculator was assessed in comparison to the observed incidence of complications us for risk stratification are necessary for patients undergoing ALIF.Level of Evidence 3.
The ACS NSQIP surgical risk calculator is an adequate predictive tool for a subset of complications after ALIF including acute kidney injury/progressive renal insufficiency, surgical site infections, and discharge to non-home facilities. However, it is a poor predictor for all other complication groups. The reliability of the ACS NSQIP surgical risk calculator is limited, and further identification of models for risk stratification are necessary for patients undergoing ALIF.Level of Evidence 3.
Randomized clinical study.

Our study was planned to determine the effect of Matrix Rhythm Therapy (MRT) on pain, level of disability and quality of life in chronic low back pain.

Low back pain is a complex and heterogeneous disorder. Different therapy options can be applied in the treatment of low back pain. In the literature, there are very few studies showing the effect of MRT in patients with chronic low back pain.

A total of 32 participants with a mean age of 36.41 ± 8.91 years were randomly divided into two groups (intervention group and control group). Each participant was treated with ten sessions a combined physiotherapy program (hot pack, transcutaneous electrical nerve stimulation, therapeutic ultrasound, home exercise and patient education program). Additionally, intervention group received six sessions of MRT. Pain (McGill Pain Questionnaire), level of disability (Oswestry Disability Index) and quality of life (Short Form-36) were measured before and after the treatment programme.

When pre- and post-treatment results were compared in the intervention group, a statistically significant difference was found in total pain level, disability level, and all subdimensions except the "Emotional Role" subdimension of SF-36 and total SF-36 scores (p≤0.
