The patients with baseline MW had inferior HRQoL for up to 3 years compared to that of those without MW; however, the amount of improvement in HRQoL was comparable. Timely follow-up is important to find out the deterioration of motor function.Level of Evidence 4.
A retrospective multi-center study.

To determine the surgical site infection (SSI) rate, associated risk factors, and causative pathogens in pediatric patients with spinal deformity.

There have been no extensive investigations of the risk factors for SSI in Japan.

Demographic data, radiographic findings, and the incidence of SSI were retrospectively analyzed in 1449 pediatric patients who underwent primary definitive fusion surgery for spinal deformity at any of 15 institutions from 2015 to 2017. SSI was defined according to the US Centers for Disease Control and Prevention guideline.

The incidence of all SSIs was 1.4% and that of deep SSIs was 0.76%. The most common pathogenic microbes were methicillin-resistant staphylococci (n=5) followed by gram-negative rods (n = 4), methicillin-sensitive staphylococci (n = 1), and others (n = 10). In univariate analysis, younger age, male sex, a diagnosis of kyphosis, type of scoliosis, American Society of Anesthesiologists (ASA) class ≥3, mental retardation u and administration of antibiotic therapy twice daily.Level of Evidence 3.
The overall infection rate was low. The most common causative bacteria were methicillin-resistant followed by gram-negative rods. Independent risk factors for SSI in pediatric patients undergoing spinal deformity surgery were scoliosis etiology, ASA class 3, and administration of antibiotic therapy twice daily.Level of Evidence 3.
Prospective randomized comparative (controlled) study.

Management of the severe postoperative back pain followed the major spinal surgeries remains a challenge. The search is going on to find simple, efficient, and reliable perioperative analgesia with low side effects. We aimed to investigate the efficacy of intraoperative freehand erector spinae plane block (ESBP) after spinal surgeries.

A few case reports and randomized controlled studies demonstrated the analgesic efficacy of ESPB in spinal surgeries. AZD9291 research buy Up-to-date, no randomized controlled studies investigated the effectiveness of ESPB on spinal instrumentation surgeries.

We randomly divided fifty-six consecutive adult patients who underwent posterior spinal instrumentation and fusion for spondylolisthesis into two groups. The study (ESPB) group (n = 28) received intraoperative freehand bilateral ESPB with a 20 ml mixture solution of 0.25% bupivacaine and 1.0% lidocaine equally divided into all operating levels. In the control group (n = 28), 20 ml ents with spondylolisthesis, it can relieve postoperative backache and reduce opioid consumption.Level of Evidence 1.
Intraoperative ESPB as a part of multimodal analgesia was effective. For posterior instrumented patients with spondylolisthesis, it can relieve postoperative backache and reduce opioid consumption.Level of Evidence 1.
Three-arm, parallel, randomized, placebo-controlled, assessor-blinded trial.

To compare the immediate effect of manual therapy at the upper thoracic spine on the cardiovascular autonomic control of patients with musculoskeletal pain.

Musculoskeletal pain increases the risk of cardiovascular events. Thus, manual therapy applied to the upper thoracic region is likely efficient to improve the cardiac autonomic control.

The study included 59 patients with musculoskeletal pain enrolled at an outpatient clinic. Participants were randomly assigned to spinal manipulation (n = 19), myofascial manipulation (n = 20), or placebo (n = 20) administered to the upper thoracic region. Resting heart rate variability provided indexes of the cardiac autonomic control, and the blood pressure response to the cold pressor test as a proxy of the sympathetic responsiveness to a stressor stimulus.

Groups were similar for baseline variables except for blood pressure. Two-way repeated-measures ANCOVA revealed that only spinal inal manipulation on the upper thoracic spine led to an immediate improvement in the resting cardiac autonomic control without an effect on the blood pressure responsiveness to a sympathoexcitatory stimulus. Myofascial manipulation or placebo did not change cardiovascular autonomic control.Level of Evidence 2.
A retrospective analysis (2015-2019) of data collected from patients who underwent posterior lumbar spinal surgery.

This study aims to identify the incidence, perioperative hematological characteristics, potential prognostic indicators, and risk factors of deep venous thrombosis (DVT) in the lower limbs after posterior lumbar spinal surgery. Eliminating risk factors or taking measures against patients at risk may reduce the incidence of DVT.

Deep venous thromboses have been extensively studied in other reconstructive surgeries. Present literatures provide limited evidence for determining the prognostic and risk factors for this complication after spinal surgery.

Patients who underwent posterior lumbar spinal surgery with internal fixation in the Spine Surgery Center of Peking Union Medical College Hospital (PUMCH) were evaluated. The patient demographics, the number of operative segments, the hematological and biochemical parameters on baseline and postoperative day one, and the presence of DVTs were operative prophylactic anti-coagulation treatment might be warranted for patients with high D-dimer or low potassium levels before the procedure.Level of Evidence 4.
Retrospective multicenter study.

This study aimed to investigate the incidence and risk factors of subjacent disc wedging (SDW) in adolescent idiopathic scoliosis (AIS) patients with Lenke type 5 curve.

SDW is frequently observed after surgery; however, data about its mechanism and relations with outcome are limited.

Data of 59 AIS patients with Lenke type 5 curves who underwent posterior spinal fusion to L3 as the lowest instrumented vertebra (LIV) were retrospectively analyzed. The subjacent disc angle (SDA) was defined as the angle between L3 (LIV) and L4. SDW was defined as the absolute value of SDA ≥10° at 2-year post-operation. The incidence of SDW was investigated between non-selective and selective thoracolumbar/lumbar (TL/L) fusion group. In the selective group, patients with and without SDW were compared.

Among 59 patients, 11 had nonselective and 48 had selective fusion. No patients in the non-selective group showed SDW vs 13 patients in the selective group (27%) showed SDW. In the selective group, patients with SDW showed significantly greater main thoracic (MT) curve, apical vertebral translation of the MT curve, upper instrumented vertebra tilt, LIV tilt, and SDA at 2 years post-operation, while no differences were found in the coronal balance nor clinical outcome.
