A Proposed Personalized Spine Care Protocol (SpineScreen) to Treat Visualized Pain Generators: An Illustrative Study Comparing Clinical Outcomes and Postoperative Reoperations between Targeted Endoscopic Lumbar Decompression Surgery, Minimally Invasive TLIF and Open Laminectomy.

Background: Endoscopically visualized spine surgery has become an essential tool that aids in identifying and treating anatomical spine pathologies that are not well demonstrated by traditional advanced imaging, including MRI. These pathologies may be visualized during endoscopic lumbar decompression (ELD) and categorized into primary pain generators (PPG). Identifying these PPGs provides crucial information for a successful outcome with ELD and forms the basis for our proposed personalized spine care protocol (SpineScreen).

Differential Agnostic Effect Size Analysis of Lumbar Stenosis Surgeries.

Study Design: A meta-analysis of 89 randomized prospective, prospective, and retrospective studies on spinal endoscopic surgery outcomes.

Objective: The study aimed to provide familiar Oswestry Disability Index (ODI), visual analog scale (VAS) back, and VAS leg effect size (ES) data following endoscopic decompression for sciatica-type back and leg pain due to lumbar herniated disc, foraminal, or lateral recess spinal stenosis.

Background: Higher-grade objective clinical outcome ES data are more suitable than lower-grade clinical evidence, including cross-sectional retrospective study outcomes or expert opinion to underpin the ongoing debate on whether or not to replace some of the traditional open and with other forms of minimally invasive spinal decompression surgeries such as the endoscopic technique.

Materials And Methods: To improve the statistical power of studying the durability of endoscopes with routine lumbar endoscopy, the authors performed a retrospective survey study among endoscopic spine surgeons by email and chat groups on social media networks WhatsApp and WeChat. Descriptive and correlative statistics were done on the surgeon's responses recorded in multiple-choice questions.

Dural Tears During Lumbar Spinal Endoscopy: Surgeon Skill, Training, Incidence, Risk Factors, and Management.

Background: Incidental dural tears during lumbar endoscopy can be challenging to manage. There is limited literature on their appropriate management, risk factors, and the clinical consequences of this typically uncommon complication.

Materials And Methods: To improve the statistical power of studying durotomy with lumbar endoscopy, we performed a retrospective survey study among endoscopic spine surgeons by email and chat groups on social media networks, including WhatsApp and WeChat.

COVID-19 and Myocardial Injury in a Brazilian ICU: High Incidence and Higher Risk of In-Hospital Mortality.

Background: The incidence of myocardial injury (MI) in patients with COVID-19 in Brazil and the prognostic impact of MI have not been elucidated.

Objectives: To describe the incidence of MI in patients with COVID-19 in the intensive care unit (ICU) and to identify variables associated with its occurrence. The secondary objective was to assess high-sensitivity troponin I as a predictor of in-hospital mortality.

BARE SPOT LOCATION IN GLENOID CAVITY: COMPARISON BETWEEN ARTHROSCOPY AND CT SCAN.

Objective: To assess whether Bare Spot is previously displaced by proportion (MEASURE BP-A × 1.25/MEASURE BP-P = 1).

Methods: 35 patients with surgical indication for rotator cuff injury repair were evaluated.

Viscossuplementation for the treatment of osteoarthritis of the knee: A protocol for an umbrella review of systematic reviews with meta-analyses of randomized controlled trials.

Background: Knee osteoarthritis (KOA) is a common chronic disease with worldwide prevalence of 10% to 79%, with costs ranging from $560 to $635 billion for year in United States of America. The main guidelines recommend interventions with undesirable adverse events (AE) or highly dependent on the patient's persistence. Thus, intra-articular (IA) therapies appear to be attractive in patients with KOA, as well as a valid therapy by maximizing effects locally in the joint and limiting systemic AE.

Feasibility of Using Intraoperative Neuromonitoring in the Prophylaxis of Dysesthesia in Transforaminal Endoscopic Discectomies of the Lumbar Spine.

(1) Background: Postoperative nerve root injury with dysesthesia is the most frequent sequela following lumbar endoscopic transforaminal discectomy. At times, it may be accompanied by transient and rarely by permanent motor weakness. The authors hypothesized that direct compression of the exiting nerve root and its dorsal root ganglion (DRG) by manipulating the working cannula or endoscopic instruments may play a role.

Surgical treatment of shoulder instability with trans-subscapularis transfer of the biceps long tendon.

Our objective is to describe the long biceps tendon transfer technique for the treatment of shoulder anterior instability. In this procedure, the long tendon of the biceps brachii is detached from the supraglenoid tubercle and transferred to the anterior edge of the glenoid cavity through a subscapularis tenotomy, reproducing the sling effect and increasing the anterior block. The technique is easy to perform and minimizes the risks of the coracoid process transfer.

Is the Bare Spot reliable for the bone loss measurement?

Background: To evaluate the reliability of the Bare Spot (BS) as an anatomical landmark for the intra-operative definition of bone loss in anterior shoulder instability.

Methods: The distances from the BS to the anterior (BS-A), posterior (BS-P) and inferior margins of the glenoid cavity were determined both under arthroscopic visualization and by an open approach in 20 shoulders.

Results: The BS did not coincide with the centre of the glenoid cavity of the studied shoulders because the BS-P distance was greater than the BS-A distance ( < 0.

Swimming as Treatment of Scapular Dyskinesis.

Scapular dyskinesis is quite frequent and can lead to shoulder pain. The diagnosis is essentially clinical. The main cause is muscle imbalance, between the trapezius, rhomboids, and pectoralis minor.
