Determinants of Operative Time in Arthroscopic Rotator Cuff Repair.

Arthroscopic rotator cuff repairs have been reported to take between 72 and 113 min to complete. This team has adopted its practice to reduce rotator cuff repair times. We aimed to determine (1) what factors reduced operative time, and (2) whether arthroscopic rotator cuff repairs could be performed in under 5 min.

Predictors of Return to Work Following Primary Arthroscopic Rotator Cuff Repair: An Analysis of 1502 Cases.

Background: It is undetermined which factors predict return to work after arthroscopic rotator cuff repair.

Purpose: To identify which factors predicted return to work at any level and return to preinjury levels of work 6 months after arthroscopic rotator cuff repair.

Study Design: Case-control study; Level of evidence, 3.

An evaluation of shear wave elastographic characteristics of the supraspinatus tendon after rotator cuff repair.

Background: The main complication of rotator cuff repair is retear, which is most common in older patients and patients with greater tear sizes. However, it is unknown why these factors are associated with increased rates of retear. The aim of this study was to determine whether the factors associated with rotator cuff retear (age, tear size, sex, history of trauma, and duration of symptoms) are also associated with decreased mechanical stiffness of the supraspinatus tendon after repair, as assessed by shear wave elastography.

A biomechanical comparison of posterior fixation approaches in lumbar fusion using computed tomography based lumbosacral spine modelling.

Extreme lateral interbody fusion (XLIF) may be performed with a standalone interbody cage, or with the addition of unilateral or bilateral pedicle screws; however, decisions regarding supplemental fixation are predominantly based on clinical indicators. This study examines the impact of posterior supplemental fixation on facet micromotions, cage loads and load-patterns at adjacent levels in a L4-L5 XLIF at early and late fusion stages. CT data from an asymptomatic subject were segmented into anatomical regions and digitally stitched into a surface mesh of the lumbosacral spine (L1-S1).

Measuring compressive loads on a 'smart' lumbar interbody fusion cage: Proof of concept.

There are several complications associated with lumbar interbody fusion surgery however, pseudarthrosis (non-union) presents a multifaceted challenge in the postoperative management of the patient. Rates of pseudarthrosis range from 3 to 20 % in patients with healthy bone and 20 to 30 % in patients with osteoporosis. The current methods in post-operative follow-up - radiographs and CT, have high false positive rates and poor agreement between them.

Biomechanical and morphological comparison of two interposition graft rotator cuff repair techniques.

Background: Interposition graft rotator cuff repair is one option for the treatment of massive, otherwise irreparable rotator cuff tears. It is undetermined how different suturing techniques influence morphology at the patch-tendon interface in interposition rotator cuff repairs, particularly with respect to increased cross-sectional area at the repair site post-exposure to cyclic loading, which may influence healing. We aimed to analyze how the morphology of the grafts used in polytetrafluoroethylene (PTFE) interposition rotator cuff repairs differed according to whether the graft was secured using the multiple mattress technique or the weave technique respectively.

Stiffness and arthroscopic rotator cuff repair: a literature review.

Background And Objective: Tendon retear is the most common complication following rotator cuff repair surgery. Understanding the factors that are associated with greater risks of retear is important so surgeons can provide accurate prognostic information to patients. Advanced age and larger tear size have been shown to be associated with greater risk of retear at 6 months using multiple logistic regression analysis.

Comparative evaluation of the efficacy of a novel tetracycline-coated suture with triclosan-coated and noncoated sutures on bacterial load reduction: A prospective study.

Background: Surgical site infection (SSI) is one of the common postoperative complications observed after various periodontal surgeries, and sutures play a vital role in its causation. Thus, the aim of this study is to evaluate and compare the efficacy of a novel tetracycline-coated suture with triclosan-coated and nonantibacterial-coated sutures on bacterial load reduction to prevent SSI by measuring the zone of inhibition.

Materials And Methods: Twenty systemically healthy individuals with moderate chronic periodontitis were included in this study.

Fibrillar matrix, Echogenicity, Contour, Thickness, and Suture (FECTS) vs. Global: A comparison of 2 scales developed to assess ultrasound images post rotator cuff repair.

Background: Ultrasound is commonly used to assess rotator cuff repair (RCR), but no standardized criterion exists to characterize the tendon.

Purpose: The aims of this study were to (1) develop content validity for ultrasound specific criteria to grade the postoperative appearance of a tendon after RCR, (2) assess the reliability of the criteria, and (3) assess the feasibility to use these assessments.

Methodology: Following expert consultation and literature review for content validity, 2 scales were created: 1) the Fibrillar matrix, Echogenicity, Contour, Thickness, and Suture (FECTS) scale and 2) the Rotator Cuff Repair-Investigator Global Assessment (RCR-IGA).

Background: It is undetermined how effective superior capsule/capsular reconstruction (SCR) is, and which factors influence clinical outcomes.

Questions/purposes: (1) To identify which factors influence outcomes in SCR, (2) to evaluate the effect of graft integrity on clinical outcomes, and (3) to compare SCR to other procedures for irreparable rotator cuff tears.

Methods: PubMed and EMBASE databases were searched for clinical SCR studies.

Sports Participation After Reverse Total Shoulder Replacement.

Background: Reverse total shoulder replacement (RTSR) is becoming a popular and reliable treatment for rotator cuff arthropathy. However, little is known about the ability to participate in sports after surgery.

Purpose: To determine to what extent RTSR will allow patients to participate in sporting activities and identify the associated factors that could affect postoperative sports participation.

Clinical and Research MRI Techniques for Assessing Spinal Cord Integrity in Degenerative Cervical Myelopathy-A Scoping Review.

Background: Degenerative cervical myelopathy (DCM) manifests as the primary cause of spinal cord dysfunction and is non-traumatic, chronic and progressive in nature. Decompressive surgery is typically utilised to halt further disability and neurological dysfunction. The limitations of current diagnostic options surrounding assessment and prognostic potential render DCM still largely a clinical diagnosis.

Stand-alone anterior cervical decompression and fusion surgery: A cohort study evaluating a shaped cage without plates or screws.

Background: The anterior approach to the cervical spine is the most commonly used surgery with effective decompression and less surgical trauma. Anterior plate construct (APC) is considered a standard technique. However, it appears to cause implant failure and postoperative dysphagia.

Synthetic polytetrafluoroethylene patches for irreparable rotator cuff tears-how are they doing at 5 years?

Background: Treating massive and irreparable rotator cuff tears are problematic. Several studies have reported that polytetrafluoroethylene (PTFE) patches demonstrated excellent construct integrity and positive clinical and patient outcomes. However, these studies either had small sample sizes or short follow-up periods.

Tear Size and Stiffness Are Important Predictors of Retear: An Assessment of Factors Associated with Repair Integrity at 6 Months in 1,526 Rotator Cuff Repairs.

Unlabelled: This study aimed to identify whether early postoperative shoulder stiffness is associated with improved healing following rotator cuff repair, and if so, how this factor might interact with other factors known to affect rotator cuff repair integrity.

Methods: We conducted a retrospective analysis of prospectively collected data from 1,526 primary arthroscopic rotator cuff repairs. Six-week range of motion was assessed to determine shoulder stiffness, and repair integrity was evaluated at 6 months by ultrasound.

Pain, paresthesia, and the rotator cuff: the prevalence and magnitude of shoulder pain and hand numbness and tingling before and after rotator cuff repair.

Background: Shoulder pain and loss of function are classically associated with rotator cuff tears, while paresthesia of the hand is not. We noted anecdotally that paresthesia of the arm was common in patients presenting with rotator cuff tears. The purpose of this study was to determine the prevalence and magnitude of hand paresthesia, its relationship to pain, and how surgery affected these symptoms.

Postoperative Pain and Paresthesia in Labral Repairs of the Shoulder: Location Does Matter.

Background: Favorable outcomes have been reported regarding postoperative shoulder pain and function after repair of anteroinferior (Bankart) glenohumeral labral tears. However, the outcomes of patients after repair of isolated superior labral anterior-posterior (SLAP) tears are a contentious topic. The authors have also anecdotally noted that patients evaluated with labral tears complained of numbness and tingling in their ipsilateral hand.

Demographic study of 366 cases of oral leukoplakia and immunohistochemical analysis - An institutional study.

Background: It has been reported that oral squamous cell carcinoma (OSCC) is associated with the presence of potentially malignant disorders (PMDs) in 15%-48% of cases. Among PMDs, oral leukoplakia (OL) is the most common, with 16%-62% of cases associated with OSCC. Hence, in the present study, we have analyzed demographic data and re-evaluated immunohistochemical (IHC) data of OL cases and aimed to correlate the clinical, histopathological and IHC aspects of OL.

A review of bone grafting techniques for glenoid reconstruction.

Background: Traumatic anterior shoulder dislocations can cause bony defects of the anterior glenoid rim and are often associated with recurrent shoulder instability. For large glenoid defects of 20-30% without a mobile bony fragment, glenoid reconstruction with bone grafts is often recommended. This review describes two broad categories of glenoid reconstruction procedures found in literature: coracoid transfers involving the Bristow and Latarjet procedures, and free bone grafting techniques.

Patient-reported experience measures in deprescribing for hospitalised older patients: a prospective, multicentre, observational study.

Background: Hospitalisation provides an opportunity for medication review and deprescribing. Patient-reported experience measures (PREM) for deprescribing in older patients in hospital are not well described.

Aims: To pilot test and describe PREM for deprescribing in older patients, compare PREM by patient characteristics and investigate patients' awareness of medication changes on hospital discharge.

The REDD1/TXNIP Complex Accelerates Oxidative Stress-Induced Apoptosis of Nucleus Pulposus Cells through the Mitochondrial Pathway.

The death of nucleus pulposus (NP) cells is an important cause of intervertebral disc (IVD) degeneration. Redox disturbance caused by dysfunctional mitochondria has been considered as a vital risk for NP cell survival. It is valuable to identify key proteins maintaining mitochondrial function in NP cells.

Ultrasound-guided repair of the distal biceps tendon.

Surgical repair of the distal biceps tendon rupture can be a challenge, especially when patients present with a retracted tendon. The tendon stump is often difficult to find and retrieve. In this aticle, we described a technique using ultrasound imaging at the start of the procedure.

Survival-Based Biomarker Module Identification Associated with Oral Squamous Cell Carcinoma (OSCC).

Head and neck squamous cell carcinoma (HNSC) is one of the most common malignant tumors worldwide with a high rate of morbidity and mortality, with 90% of predilections occurring for oral squamous cell carcinoma (OSCC). Cancers of the mouth account for 40% of head and neck cancers, including squamous cell carcinomas of the tongue, floor of the mouth, buccal mucosa, lips, hard and soft palate, and gingival. OSCC is the most devastating and commonly occurring oral malignancy, with a mortality rate of 500,000 deaths per year.

Finite element modeling of temporal bone graft changes in XLIF: Quantifying biomechanical effects at adjacent levels.

Extreme lateral interbody fusion allows for the insertion of a large-footprint interbody cage while maintaining the presence of natural stabilizing ligaments and the facets. It is unclear how the load-distribution mechanisms through these structures alter with temporal changes in the bone graft. The aim of this study was to examine the effects of temporal bone graft changes on load distribution among the cage, graft, and surrounding spinal structures using finite element analysis.
