The efficacy and safety of leucine-enriched essential amino acids in knee osteoarthritis patients: A randomized controlled trial.

Background: Supplementation with leucine-enriched essential amino acids (LEAAs) has shown efficacy in the recovery of muscle injury and activation of muscle synthesis. Muscle function in knee osteoarthritis is a crucial factor for managing pain and preserving ambulatory function. However, the efficacy and safety of LEAAs supplementation in patients with knee osteoarthritis have not been evaluated.

Early Clinical Results of Intervertebral Joint Stabilization by Injectable Load-Sharing Polymers.

Background: Genipin is a polymer-forming collagen bonding substance that can be dissolved in a buffered carrier and injected into disc annulus tissues. Therapeutic benefit is derived from the mechanical support provided by a large number of genipin polymers attached to collagen fibers in a degraded disc.

Study Design/setting: IRB-approved prospective, multi-site, single-arm, 12-month feasibility studies were undertaken in two countries to evaluate the safety and efficacy of the genipin-based implant for treating discogenic chronic low back pain (CLBP).

Preoperative Dyeing Technique for Decreasing Radiation Exposure in Unilateral Biportal Endoscopic Spine Surgery.

Background: Minimally invasive surgery has many advantages, including early recovery and cosmetic preservation. However, the higher radiation exposure to physicians and patients has drawbacks. Preoperative tissue dyeing techniques are feasible options for reducing radiation exposure and procedure time, but their efficacy has not yet been evaluated.

Impact of the Coronavirus Disease Pandemic and Related Vaccination in an Orthopedic Clinic in the United Arab Emirates: An Observational Study.

The coronavirus disease (COVID-19) pandemic has influenced hospital visiting patterns. Although vaccination has decreased infection rates and disease severity, hospital visiting patterns and associated treatment changes related to orthopedics remain unexplored in the Middle East. Therefore, this study aimed to examine the impact of the COVID-19 pandemic and vaccination on individual departments dealing with musculoskeletal disorders in the United Arab Emirates.

Biportal endoscopic debridement and percutaneous screw fixation technique for spinal tuberculosis: how I do it.

Background: Biportal endoscopy and percutaneous screw fixation are promising techniques that can be applied to treat various degenerative spinal diseases. However, these techniques for spinal tuberculosis have not been reported.

Method: Using the biportal endoscopic technique, bilateral decompression, tissue biopsy, and granulation tissue removal were performed using the screw insertion site.

Stand-Alone Posterior Expandable Cage Technique for Adjacent Segment Degeneration with Lumbar Spinal Canal Stenosis: A Retrospective Case Series.

: Symptomatic adjacent segment degeneration (ASD) with lumbar spinal canal stenosis (LSCS) is a common complication after spinal intervention, particularly interbody fusion. Stand-alone posterior expandable cages enable interbody fusion with preservation of the previous operation site, and screw-related complications are avoided. Thus, the aim of this study was to investigate the clinicoradiologic outcomes of stand-alone posterior expandable cages for ASD with LSCS.

Water Dynamics in Unilateral Biportal Endoscopic Spine Surgery and Its Related Factors: An In Vivo Proportional Regression and Proficiency-Matched Study.

Background: Stable water dynamics during endoscopic spine surgery improves the surgeon's comfort and patient's outcomes. We aimed to measure the water dynamics during spinal surgery and identify the factors that facilitate stable water dynamics.

Methods: This open-label, prospective, proficiency-matched, in vivo study included patients with single-level degenerative spinal disease.

Can posterior stand-alone expandable cages safely restore lumbar lordosis? A minimum 5-year follow-up study.

Background: Lumbar lordosis (LL) can be restored, and screw-related complications may be avoided with the stand-alone expandable cage method. However, the long-term spinopelvic changes and safety remain unknown. We aimed to elucidate the long-term radiologic outcomes and safety of this technique.

Comparison of Reoperation after Fusion and after Decompression for Degenerative Lumbar Spinal Stenosis: A Single-Center Experience of 987 Cases.

Background And Study Aim:  Reoperation for lumbar spinal stenosis (LSS) is technically challenging. Studies comparing preoperative risk factors and reoperation outcomes between spinal fusion and spinal decompression are limited. Thus this study compared fusion and decompression with respect to reoperation rates, preoperative factors related to re-surgery, and clinical outcomes.

Clinical outcomes and cost-effectiveness of massage chair therapy versus basic physiotherapy in lower back pain patients: A randomized controlled trial.

Introduction: Low back pain is a chronic recurrent symptom, which can lower the patient's quality of life. With technological development of automated home massage systems, now offers a promising alternative to physiotherapy. However, thus far, the effectiveness of such methods has not been evaluated.

Dural Tears in Percutaneous Biportal Endoscopic Spine Surgery: Anatomical Location and Management.

Objective: To determine the rate and anatomical location of dural tears associated with spinal surgery using a percutaneous biportal endoscopic surgery (PBES) technique. We investigated the relationship between dural tears and the type of procedure and type of instrument used.

Methods: We retrospectively analyzed 643 PBES cases by reviewing the medical records, operative records, and operative videos.

Pooled analysis of unsuccessful percutaneous biportal endoscopic surgery outcomes from a multi-institutional retrospective cohort of 797 cases.

Background: Spinal percutaneous biportal endoscopic surgery (PBES) is a minimally invasive surgery; however, it is associated with several poor outcomes. This study aimed to analyze unsuccessful PBES outcomes and verify their relationships with patient satisfaction.

Methods: From May 2015 to June 2018, PBES was performed at several institutions.

Eye stabilization reflexes in traumatic and non-traumatic chronic neck pain patients.

Background: Many chronic neck pain patients experience problems with vision. These problems are possibly induced by deviations of the eye stabilization reflexes. It is not known whether these eye reflex alterations occur both in traumatic and non-traumatic neck pain patients.

Eye movements in patients with Whiplash Associated Disorders: a systematic review.

Background: Many people with Whiplash Associated Disorders (WAD) report problems with vision, some of which may be due to impaired eye movements. Better understanding of such impaired eye movements could improve diagnostics and treatment strategies. This systematic review surveys the current evidence on changes in eye movements of patients with WAD and explains how the oculomotor system is tested.

Joint position sense error in people with neck pain: A systematic review.

Background: Several studies in recent decades have examined the relationship between proprioceptive deficits and neck pain. However, there is no uniform conclusion on the relationship between the two. Clinically, proprioception is evaluated using the Joint Position Sense Error (JPSE), which reflects a person's ability to accurately return his head to a predefined target after a cervical movement.

Physical characteristics of women with severe pelvic girdle pain after pregnancy: a descriptive cohort study.

Study Design: Descriptive cohort study.

Objective: This study aims to further elucidate the differences in physical characteristics of women with severe pregnancy-related pelvic girdle pain (PGP).

Summary Of Background Data: There is increasing interest in pelvic girdle pain (PGP).

European guidelines for the diagnosis and treatment of pelvic girdle pain.

A guideline on pelvic girdle pain (PGP) was developed by "Working Group 4" within the framework of the COST ACTION B13 "Low back pain: guidelines for its management", issued by the European Commission, Research Directorate-General, Department of Policy, Coordination and Strategy. To ensure an evidence-based approach, three subgroups were formed to explore: (a) basic information, (b) diagnostics and epidemiology, and (c) therapeutical interventions. The progress of the subgroups was discussed at each meeting and the final report is based on group consensus.
