Arthroscopic Measurements Predict Knee Chondral Lesion Size More Accurately Than Magnetic Resonance Imaging, and Mechanism of Injury Influences Ability of Either Technique to Predict Graft Size.

Purpose: To compare osteochondral defect size measurements and characteristics across magnetic resonance imaging (MRI) and arthroscopy and at the time of osteochondral allograft (OCA) transplantation or autologous chondrocyte implantation (ACI).

Methods: Patients who underwent ACI and OCA transplantation at a single institution between 2015 and 2019 were retrospectively identified. Patients were excluded if they had severe osteoarthritis, MRI scans were not available for review, surgical records did not include defect sizing necessary for analysis, or operative reports were not available.

Surgeon Prescribing Patterns And Perioperative Risk Factors Associated With Prolonged Opioid Use After Total Shoulder Arthroplasty.

Introduction: The opioid epidemic in the United States has contributed to a notable economic burden and increased mortality. Total shoulder arthroplasty (TSA) has become more prevalent, and opioids are commonly used for postoperative pain management. Prolonged opioid use has been associated with adverse outcomes, but the role of surgeons in this context remains unclear.

Assessment of Food Masticatory Capability with Clear Aligners.

Unlabelled: Nowadays, aligners represent a possible therapeutical approach that combines both esthetic and function in order to address dental malocclusion. However, they require a significant level of compliance from the patient. According to the manufacturer, at least 22 h of wearing a day is demanded to reach the optimal therapeutical level; hence, aligners can only be removed during meals.

Efficacy of the Sausage Technique in Rebuilding the Crestal Buccal Bone Thickness: A Retrospective Analysis.

The goal was to evaluate the efficacy of the sausage technique in reconstructing the crestal buccal bone thickness, focusing on the distribution shape of the regenerated volume. Ten implants were placed in five patients with Cawood-Howell class IV defects. A cone beam computed tomography (CBCT) was executed at T0 (before surgery).

A Conservative Technique for Fractured Implant Abutment Screw Retrieval on an Internal Connection Implant: Proof of Concept.

Broken screw removal from the implant connection is a common but challenging process. Several proposed methods and technical solutions may result in unsuccessful removal; thus, a novel, more conservative, risk-free method is proposed as a first attempt. The proposal is to use a silicon restoration holder to be twisted counterclockwise on the dried surface of the broken fragment inside the implant connection.

Effects of socioeconomic burden on opioid use following total shoulder arthroplasty.

Background: Preoperative opioid users experience worse outcomes and higher complication rates compared to opioid-naïve patients following shoulder arthroplasty. This study evaluates the effects of socioeconomic status, as measured by the Distressed Communities Index (DCI), on pre- and postoperative opioid use and its influence on clinical outcomes such as readmission and revision surgery.

Methods: A retrospective review of patients who underwent primary shoulder arthroplasty (Current Procedural Terminology code 23472) from 2014 to 2022 at a single academic institution was performed.

Evaluation of Sterify Gel as an Adjunctive Treatment to Scaling and Root Planing in Promoting Healing of Periodontal Pockets: A Split-Mouth Randomized Controlled Trial.

Background: Periodontal disease is a common infectious disease that leads to the destruction of tooth-supporting structures. Current treatments, such as scaling and root planing (SRP), have limitations in deep and complex pockets, and antibiotic use carries the risk of resistance. Sterify Gel, a medical device composed of polyvinyl polymers, hydroxytyrosol, nisin, and magnesium ascorbyl phosphate, offers a new approach to periodontal care.

Distressed communities demonstrate increased readmission and health care utilization following shoulder arthroplasty.

Background: Socioeconomic status (SES) has been shown to affect outcomes following total shoulder arthroplasty (TSA), but little is known regarding how SES and the communities in which patients reside can affect postoperative health care utilization. With the growing use of bundled payment models, understanding what factors put patients at risk for readmission and the ways in which patients utilize the health care system postoperatively is crucial for preventing excess costs for providers. This study helps surgeons predict which patients are high-risk and may require additional surveillance following shoulder arthroplasty.

Irreparable Massive Rotator Cuff Tears: Subacromial Balloon Surgical Technique.

Massive irreparable rotator cuff tears pose a significant challenge for both the treating orthopedic surgeon and patient. Surgical treatment options for massive rotator cuff tears include arthroscopic debridement, biceps tenotomy or tenodesis, arthroscopic rotator cuff repair, partial rotator cuff repair, cuff augmentation, tendon transfers, superior capsular reconstruction, subacromial balloon spacer, and ultimately reverse shoulder arthroplasty. The present study will provide a brief overview of these treatment options along with a description of the surgical technique for subacromial balloon spacer placement.

Effects of Patient Comorbidities and Demographics on Episode-of-Care Costs Following Total Shoulder Arthroplasty.

Background: As demand for shoulder arthroplasty grows, adequate cost containment is of importance. Given the historical use of bundle payments for lower extremity arthroplasty, it is reasonable to anticipate that such programs will be universally implemented in shoulder arthroplasty. This project evaluates how patient demographics, medical comorbidities, and surgical variables affect episode-of-care costs in an effort to ensure accurate reimbursement scales and equitable access to care.

Serotonin Reuptake Inhibitor Increases Pseudarthrosis Rates in Anterior Cervical Discectomy and Fusions.

Purpose: To determine (1) the effects of serotonin reuptake inhibitors in pseudarthrosis rates after anterior cervical decompression and fusion (ACDF) and (2) to identify patient-reported outcome measures in patients taking serotonin reuptake inhibitors.

Overview Of Literature: Recent literature suggests that selective serotonin reuptake inhibitors (SSRIs) may inhibit fracture healing via downregulation of osteoblast differentiation.

Predicting Hospital Readmissions After Total Shoulder Arthroplasty Within a Bundled Payment Cohort.

Introduction: Given the rising demand for shoulder arthroplasty, understanding risk factors associated with unplanned hospital readmission is imperative. No study to date has examined the influence of patient and hospital-specific factors as a predictive model for 90-day readmissions within a bundled payment cohort after primary shoulder arthroplasty. The purpose of this study was to determine predictive factors for 90-day readmissions after primary shoulder arthroplasty within a bundled payment cohort.

Impact of Smoking Habit on Peri-Implant Indicators following Different Therapies: A Systematic Review.

Peri-implant disease and its treatment is becoming a major concern for clinicians as the number of implants placed each year is rising. Smoking is a common habit, and it is associated with an increased risk of developing peri-implant disease. The role of smoking in the response to peri-implant treatment has never been investigated.

Acetabular Retroversion: Dysplasia in Disguise that Leads to Early Arthritis of the Hip.

We aimed to assess the prevalence of acetabular retroversion (AR) in patients undergoing total hip replacement (THA) based on age. We retrospectively compared preoperative anteroposterior pelvic radiographs of patients younger than 40 years of age who underwent THA with the age- and body mass index-matched control of 40 years and older patients. Retroversion was determined based on the presence of cross-over sign, ischial spine sign, posterior wall sign, and elephant's ear sign with data stratified based on presence of dysplasia.

Effects on Muscular Activity after Surgically Assisted Rapid Palatal Expansion: A Prospective Observational Study.

The study aims to investigate the modifications in the temporalis and the masseter activity in adult patients before and after SARPE (Surgically Assisted Rapid Palatal Expansion) by measuring electromyographic and electrokinesographic activity. 24 adult patients with unilateral posterior crossbite on the right side were selected from the Orthodontic Department of the University of Milan. Three electromyographic and electrokinesographic surface readings were taken respectively before surgery (T0) and 8 months after surgery (T1).

Marijuana Use and its Effect on Clinical Outcomes and Revision Rates in Patients Undergoing Anterior Cervical Discectomy and Fusion.

Study Design: A retrospective cohort study.

Objective: To determine if (1) preoperative marijuana use increased complications, readmission, or reoperation rates following anterior cervical discectomy and fusion (ACDF), (2) identify if preoperative marijuana use resulted in worse patient-reported outcome measures (PROMs), and (3) investigate if preoperative marijuana use affects the quantity of opioid prescriptions in the perioperative period.

Summary Of Background Data: A growing number of states have legalized recreational and/or medical marijuana, thus increasing the number of patients who report preoperative marijuana use.

Lateral femoral distraction is a safe and necessary adjunct for articulator visualization during the operative treatment of tibial plateau fractures.

Introduction: Recent evidence suggests use of lateral femoral distractor (LFD) to aid in visualization during surgery for tibial plateau fractures (TPF) may result in an unacceptably high rate of iatrogenic peroneal nerve palsy. We sought to evaluate femoral distractor use for open reduction internal fixation (ORIF) of TPF and quantify the incidence of peroneal nerve palsy.

Methods: We retrospectively evaluated all patients undergoing ORIF of TPF between 2014 and 2019 by a single fellowship trained orthopaedic traumatologist at a single Level 1 trauma center.

Increased Surgical Site Subcutaneous Fat Thickness Is Associated with Infection after Posterior Cervical Fusion.

Previous literature has associated increased body mass index (BMI) with risk of surgical site infection (SSI) after posterior cervical fusion (PCF) surgery. However, few studies have examined the association between local adiposity and risk of SSI, re-admission, and re-operation after PCF. Local adiposity is easily measured on pre-operative magnetic resonance imaging (MRI) and may act as a more accurate predictor compared with BMI.

Evaluation of Breaking Force of Different Suture Materials Used in Dentistry: An In Vitro Mechanical Comparison.

The success of surgical procedures is strictly related to the biomechanical properties of the suture. Mechanical comparisons are scarcely reported in the literature, so the purpose of the present study was to evaluate and compare the mechanical behavior of different sutures commonly used in oral surgery in terms of traction resistance. Sutures made of eight different materials were analyzed: silk (S), polyglycolide-co-caprolactone (PGCL), polypropylene (PP), rapid polyglycolide (rPGA), standard polyglycolide (PGA), polyamide (PA), polyester (PE), and polyvinylidene fluoride (PVDF).
