    Abstract Background: While massive and irreparable rotator cuff tears (MIRCTs) have been abundantly studied, inconsistent definitions in the literature and theories about pain and dysfunction related to them can be difficult to navigate when considering an individual patient.
    Purpose: To review the current literature for definitions and critical concepts that drive decision-making for MIRCTs.
    Study design: Narrative review.
    Methods: A search of the PubMed database was performed to conduct a comprehensive literature review on MIRCTs. A total of 97 studies were included.
    Results: Recent literature reflects added attention to clarifying the definitions of "massive, "irreparable," and "pseudoparalysis." In addition, numerous recent studies have added to the understanding of what generates pain and dysfunction from this condition and have reported on new techniques for addressing them.
    Conclusion: The current literature provides a nuanced set of definitions and conceptual foundations on MIRCTs. These can be used to better define these complex conditions in patients when comparing current surgical techniques to address MIRCTs, as well as when interpreting the results of new techniques. While the number of effective treatment options has increased, high-quality and comparative evidence on treatments for MIRCTs is lacking.

    Abstract A biocomposite interference screw with an open architecture was developed to provide a greater available surface area for bone ingrowth compared with conventional solid interference screws. We herein describe a prospective, single-cohort study conducted using this interference screw in anterior cruciate ligament (ACL) reconstruction. Sixty subjects (mean age, 34.9 years; standard deviation, 10.6) undergoing ACL repair using the biocomposite interference screw were enrolled at 3 sites in the United States. Subjects were followed preoperatively (baseline) and postoperatively at 6 months and 1 year. The primary endpoint was graft fixation survival rate at 6 months and 1 year. Secondary endpoints included graft survival (failure defined as that occurring for any reason); International Knee Documentation Committee (IKDC) score (exam and subjective forms); Tegner Activity form; Lysholm score; and EQ (EuroQuol)-5D-5L index score and visual analogue scale. There was a 100 % rate of graft fixation survival at 6 months (54/54; 95 % confidence interval [CI]: 100-100) and 1 year (50/50; 95 % CI: 100-100). One patient experienced a complete tear of the ACL 5 months following index surgery, resulting in graft survival rates of 98.1 % (53/54; 95 % CI: 94.6–100) at 6 months at 98.0 % (49/50; 95 % CI: 94.1–100) at 1 year. Significant improvements (p < .0001) were obtained between baseline and 6 months for the majority of patient-reported outcomes, and were maintained out to 1-year follow up. There was no significant difference over baseline in the IKDC sub-scale of symptoms. Nine patients (15.0 %) experienced serious adverse events during the course of the study; three of these patients’ adverse events were considered possibly or definitely related to the procedure device (ACL tear, pulmonary embolism/deep vein thrombosis, and a patellar fracture). In conclusion, this biocomposite interference screw has a favorable safety and efficacy profile at 1 year, with no failures of graft fixation, noted during that time.

    Abstract Background: With advancements in the technology, techniques, and biomechanical understanding of shoulder arthroplasty, higher rates of postoperative return to various sports have been seen in the past decade.
    Purpose: To observe the return-to-golf rate after various types of shoulder arthroplasty (anatomic total shoulder arthroplasty [TSA], hemiarthroplasty [HA], and reverse total shoulder arthroplasty [RSA]) and also to review the protocols for return to golf.
    Study design: Scoping review; Level of evidence, 4.
    Methods: The PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines were followed in a search of PubMed, JSTOR, Google Scholar, ScienceDirect, and CORE using the keywords "return to sport,""shoulder arthroplasty,""golf,""TSA,""shoulder arthroplasty,""hemiarthroplasty,""reverse shoulder arthroplasty,""RSA,""sports," and "athlete." Of 145 preliminary results, 10 retrospective studies (n = 178 patients) published between 1998 and 2021 were included in the final analysis.
    Results: The mean patient age was 65 years. Of the 172 patients with reported return-to-sport rates, the mean return-to-golf rate was 75.8% for all types of shoulder arthroplasty. Of these 172 patients, 107 patients were categorized by type of procedure: Anatomic TSA had the highest return-to-golf rate at 77.6% (49/107), followed by HA at 64.3% (14/107) and RSA at 59.1% (44/107). Four studies commented on return to the full 18 holes of golf, with a return-to-sport timeline ranging from 5 to 6 months postoperatively. One study specified the return-to-golf timeline based on the type of shot and reported the mean number of weeks before putting, chipping, and returning to the course as 20, 22, and 27 weeks, respectively. Two studies that reported on golf playing frequency noted an increase from before to 1 year after TSA, from a mean of 1.6 and 0.7 times per week to 2.0 and 1.7 times per week, respectively. Only 1 study, published in 1998, provided a comprehensive return-to-golf protocol.
    Conclusion: The return-to-golf rate after shoulder arthroplasty was highest after anatomic TSA (78%) compared with HA (64%) and RSA (59%). The most commonly reported duration before returning to a full 18 holes was 5 to 6 months, but patients returned to putting and chipping earlier.

    Abstract Background: Estimating glenoid bone loss when assessing the unstable shoulder can be challenging. The aim of this article was to describe a simple derived ratio to estimate glenoid bone loss.
    Methods: When the glenoid is damaged and bone is damaged because of instability, the anterior aspect of the glenoid loses its normal curvature and becomes flattened. In geometry, this represents a chord. There are 3 assumptions for the calculations: (1) the lower glenoid is a circle; (2) there is a relationship between the glenoid height and the diameter of the glenoid circle; and (3) the length of the measured bone loss of the glenoid is a chord. Two measurements are required: glenoid height and length of the glenoid defect. The calculations involved in the ratio are reviewed.
    Results: If the ratio of the length of the bone defect to the glenoid height is 0.5 (otherwise, 50% of the height), the estimated bone loss is 12%.
    Conclusion: Glenoid bone loss can be estimated by measuring the length of the glenoid and the length of the defect.

    Abstract Background: Shoulder arthroscopy is commonly performed in the beach chair position, which has been linked to cerebral oxygen desaturation. Previous studies comparing general anesthesia (GA) to total intravenous anesthesia (TIVA) using propofol indicate that TIVA can preserve cerebral perfusion and autoregulation, as well as shorten recovery time and reduce the incidence of postoperative nausea and vomiting. However, few studies have evaluated the use of TIVA in shoulder arthroscopy. Thus, this study seeks to determine if TIVA is superior to traditional GA methods in terms of improving operating room efficiency, shortening recovery time, and reducing adverse events while theoretically preserving cerebral autoregulation in patients undergoing shoulder arthroscopy in the beach chair position.
    Methods: This is a retrospective study of patients undergoing shoulder arthroscopy in the beach chair position, comparing 2 anesthetic techniques. One hundred fifty patients were included (75 TIVA and 75 GA). Unpaired
    Results: Compared to GA, TIVA significantly improved phase 1 recovery time (53.2 ± 32.9 min compared to 65.8 ± 41.3 min;
    Conclusion: TIVA may be a safe and efficient alternative to GA in shoulder arthroscopy in the beach chair position. Larger scale studies are needed to evaluate the risk of adverse events related to impaired cerebral autoregulation in the beach chair position.

    Method: An observational study in term neonates at risk of seizures admitted to a single tertiary level neonatal intensive care unit. Synchronised high-resolution physiological data (ECG, pulse oximetry, respiration) and EEG/amplitude-integrated EEG (aEEG) monitoring were recorded. Sections of traces with evidence of clear EEG seizure activity were compared with physiological data recorded at the same time.
    Results: 22/44 (50%) neonates who had aEEG monitoring were noted to have electrographic seizures. Physiologic download measurements were available for 11 of these neonates. In nine of these, an acute drop in oxygen saturation (SpO
    Conclusion: Acute decreases in SpO
