No Wound Healing Complications or Recurrences Were Seen and a High Level of Satisfaction Was Reported in Patients Who Underwent Endoscopic Olecranon Bursectomy for Recalcitrant Olecranon Bursitis.

Purpose: To determine the outcomes of endoscopic olecranon bursectomy for the treatment of recalcitrant olecranon bursitis in one surgeon's practice. Methods: A retrospective analysis was conducted on all patients who underwent an endoscopic olecranon bursectomy for the treatment of recalcitrant olecranon bursitis between January 2018 and May 2021 at one surgeon's practice. Demographic variables as well as causes for olecranon bursitis such as aseptic, septic, and gouty tophi were recorded. In addition, any complications such as infection, recurrence, wound failure, or hospitalizations were documented, with wound dehiscence, recurrence of bursitis, and return to the operating room being the primary outcome measures. During the final phone encounter before finalizing this project, patients were queried to obtain the patient-reported form of the American Shoulder and Elbow Surgeons Elbow Questionnaire, quick Disabilities of the Arm Shoulder and Hand score, and the Single Assessment Numeric Evaluation score. Results: Our study included 28 patients (23 male and 5 female) with an average age of 68 years (ranging from 33-86 years), all of whom had follow-up. The average follow-up was 24.7 months (range 3-42 months). There were 15 cases (54%) of aseptic bursitis, 13 cases (46%) of septic bursitis, and 7 cases (25%) that contained gouty tophi (5 aseptic and 2 septic). Of the 28 patients, 4 experienced complications. These all occurred within 3 months of surgery. One necessitated hospitalization and intravenous antibiotics, 2 were minor infections treated with oral antibiotics, and one was swelling treated successfully with in-office aspiration. Overall, 24 (86%) patients reported no issues at all related to the surgery. There were no instances of recurrence, wound failure, or secondary operations. Of the 20 (71.4%) patients who were reached for patient-reported form of the American Shoulder and Elbow Surgeons Elbow Questionnaire, quick Disabilities of the Arm Shoulder and Hand score, and Single Assessment Numeric Evaluation scores, all 20 patients reported no residual pain or difficulties with daily tasks. Average satisfaction with the procedure was 9.9 of 10 and, on average, patients reported that their elbow functionality was 96% with 100% representing completely normal. Conclusions: In this population, patients who underwent endoscopic olecranon bursectomy experienced no recurrences or wound-healing complications necessitating return to the operating room. In addition, patients reported high function and satisfaction after the procedure. Level of Evidence: Level IV, therapeutic case series.

Stop the leak!: Mitigating potential exposure of aerosolized COVID-19 during laparoscopic surgery.

BACKGROUND: Viral particles have been shown to aerosolize into insufflated gas during laparoscopic surgery. In the operating room, this potentially exposes personnel to aerosolized viruses as well as carcinogens. In light of circumstances surrounding COVID-19 and a concern for the safety of healthcare professionals, our study seeks to quantify the volumes of gas leaked from dynamic interactions between laparoscopic instruments and the trocar port to better understand potential exposure to surgically aerosolized particles. METHODS: A custom setup was constructed to simulate an insufflated laparoscopic surgical cavity. Two surgical instrument use scenarios were examined to observe and quantify opportunities for insufflation gas leakage. Both scenarios considered multiple configurations of instrument and trocar port sizes/dimensions: (1) the full insertion and full removal of a laparoscopic instrument from the port and (2) the movement of the scope within the port, recognized as "dynamic interaction", which occurs nearly 100% of the time over the course of any procedure. RESULTS: For a 5 mm instrument in a 5 mm trocar, the average volume of gas leaked during dynamic interaction and full insertion/removal scenarios were 43.67 and 25.97 mL of gas, respectively. Volume of gas leaked for a 5 mm instrument in a 12 mm port averaged 41.32 mL and 29.47 for dynamic interaction vs. instrument insertion and removal. Similar patterns were shown with a 10 mm instrument in 12 mm port, with 55.68 mL for the dynamic interaction and 58.59 for the instrument insertion/removal. CONCLUSIONS: Dynamic interactions and insertion/removal events between laparoscopic instruments and ports appear to contribute to consistent leakage of insufflated gas into the OR. Any measures possible taken to reduce OR gas leakage should be considered in light of the current COVID-19 pandemic. Minimizing laparoscope and instrument removal and replacement would be one strategy to mitigate gas leakage during laparoscopic surgery.

Relative age effect: beyond the youth phenomenon.

INTRODUCTION: Initially described in a sports context in ice hockey in 1985, the relative age effect (RAE) refers to the performance advantages of youth born in the first quarter of the birth year when trying-out for select, age-restricted sports. The competitive advantage bestowed to the relatively older athlete in their age band is the result of the older athlete being more physically and emotionally mature. These more mature players will likely go on to be exposed to better coaching, competition, teammates and facilities in their respective sport. OBJECTIVES: Our study sought to characterise the ubiquity of this effect by examining the birth distribution of some of the world's most elite athletes, Olympians. METHODS: We extended the exploration of the RAE beyond specific sports by examining the birth quarter of over 44 000 Olympic athlete's birthdates, born between 1964 and 1996. Our hypothesis was that the RAE would be prominent in both Olympic athletes as a whole and in selected subcategories of athletes. RESULTS AND CONCLUSION: The fractions of births in the first versus the fourth quarter were significantly different (p<0.001) from each other for the summer and winter Olympians, ball and non-ball sports, and team as well as individual sports. This significant difference was not gender specific. We found the general existence of the RAE in Olympic athletes regardless of global classification. Our findings suggest that coaching staff should be cognisant of the RAE when working with young athletes and should take relative age into consideration when evaluating a burgeoning athlete's abilities.
