Editor\u27s Note

We are thrilled to introduce the inaugural issue of the Bone Bulletin, DePalma Orthopaedic Society’s student-run, non-peer reviewed journal for Sidney Kimmel Medical College (SKMC) students. The journal’s aim is to provide yet another way to be involved with orthopaedics in medical school and to promote student interest in orthopaedics by reporting on diverse aspects of the field through editorial and opinion pieces. Under the close 1-on-1 mentorship of a physician from the Rothman Orthopaedic Institute, students have a hands-on opportunity to write about and directly engage with orthopaedic research and developments. Within the pages of this journal, you will find research articles, insightful reviews, thought-provoking interviews, and inspiring stories of clinical experiences. We believe that by providing an inclusive platform for students to express their ideas and share their research findings, we can foster a vibrant community of learners and thinkers dedicated to advancing the field of orthopaedic surgery. We extend our gratitude to the writers and editorial team, who have formed the contributions featured in this issue. We would also like to express our gratitude to the mentors and physicians from the Rothman Orthopaedic Institute, who have supported us throughout this journey. Your guidance, encouragement, and expertise have been invaluable in shaping this endeavor and inspiring us to pursue excellence in the field of orthopaedics. Thank you for joining us on this exciting venture. We are beyond excited to present the invaluable contributions that everyone has made for the Bone Bulletin. Sincerely,Payton Boere & Ari ClementsEditors-in-Chief, The Bone Bulleti

Latarjet Surgery Leads to Decreased Rates of Subjective Instability Compared to Bankart Repair with Concomitant Remplissage

Background: Predictive factors for performing remplissage concomitantly with arthroscopic Bankart repair include the presence of humeral or glenoid defects \u3e11% and/or revision surgery. International and societal consensus statements support these findings, as surgeons recommend the Latarjet procedure for patients with significant glenoid bone loss (\u3e15-20%) while remplissage is recommended for patients with off-track or engaging Hill-Sachs lesions without significant glenoid bone loss. While several studies have compared outcomes between Latarjet surgery and remplissage, these studies have only evaluated patients with engaging Hill-Sachs lesions, not consecutive patient cohorts indicated for each surgery. Purpose: To compare rates of recurrent instability, re-operation, revision, and return to play (RTP), as well as patient-reported outcomes including the American Shoulder and Elbow Surgeon Score (ASES), Single Assessment Numeric Evaluation (SANE), and Oxford Shoulder Instability Score (OSI) between Latarjet surgery and arthroscopic labral repair plus remplissage surgery (Remplissage) patients

Climate Change Promotes the Emergence of Serious Disease Outbreaks of Filarioid Nematodes

Filarioid parasites represent major health hazards with important medical, veterinary, and economic implications, and considerable potential to affect the everyday lives of tens of millions of people globally (World Health Organization, 2007). Scenarios for climate change vary latitudinally and regionally and involve direct and indirect linkages for increasing temperature and the dissemination, amplification, and invasiveness of vector-borne parasites. High latitude regions are especially influenced by global climate change and thus may be prone to altered associations and dynamics for complex host-pathogen assemblages and emergence of disease with cascading effects on ecosystem structure. Although the potential for substantial ecological perturbation has been identified, few empirical observations have emanated from systems across the Holarctic. Coincidental with decades of warming, and anomalies of high temperature and humidity in the sub-Arctic region of Fennoscandia, the mosquito-borne filarioid nematode Setaria tundra is now associated with emerging epidemic disease resulting in substantial morbidity and mortality for reindeer and moose. We describe a host-parasite system that involves reindeer, arthropods, and nematodes, which may contribute as a factor to ongoing declines documented for this ungulate species across northern ecosystems. We demonstrate that mean summer temperatures exceeding 14°C drive the emergence of disease due to S. tundra. An association between climate and emergence of filarioid parasites is a challenge to ecosystem services with direct effects on public health, sustainability of free-ranging and domestic ungulates, and ultimately food security for subsistence cultures at high latitudes

WSES guidelines for management of Clostridium difficile infection in surgical patients

In the last two decades there have been dramatic changes in the epidemiology of Clostridium difficile infection (CDI), with increases in incidence and severity of disease in many countries worldwide. The incidence of CDI has also increased in surgical patients. Optimization of management of C difficile, has therefore become increasingly urgent. An international multidisciplinary panel of experts prepared evidenced-based World Society of Emergency Surgery (WSES) guidelines for management of CDI in surgical patients.Peer reviewe

Cyclic Scheduling

In this paper we consider the problem of cyclic schedules such as arise in manufacturing. We introduce a new formulation of this problem that is a very simple modification of a standard job shop scheduling formulation, and which enables us to use existing constraint reasoning techniques to generate cyclic schedules. We present evidence for the effectiveness of this formulation, and describe extensions for handling multiple-capacity resources and for recovering from breaks in cyclic schedules. 1 Introduction A cyclic scheduling problem is a scheduling problem in which some set of activities is to be repeated an indefinite number of times, and it is desired that the sequence be repeating. Cyclic scheduling problems arise in domains such as manufacturing, time-sharing of processors in embedded systems, and in compilers for scheduling loop operations for parallel or pipelined architectures. In this paper, we will take the manufacturing domain as our motivation and address the cyclic vers..

Effect of Preoperative MRI Coracoid Dimensions on Postoperative Outcomes of Latarjet Treatment for Anterior Shoulder Instability.

Background: Preoperative coracoid dimensions may affect the size of the bone graft transferred to the glenoid rim and thus the postoperative outcomes of Latarjet coracoid transfer. Purpose: To determine the effect of coracoid length and width as measured on preoperative magnetic resonance imaging (MRI) on outcomes after Latarjet treatment of anterior shoulder instability. Study Design: Cohort study; Level of evidence, 3. Methods: Included were patients who underwent primary Latarjet surgery between 2009 and 2019 and had preoperative MRI scans and minimum 2-year postoperative outcomes. Longitudinal coracoid length was measured on axial MRI sequences as the distance from the coracoclavicular ligament insertion to the distal tip. Comparisons were made between shorter and longer coracoids and between narrower and wider coracoids. The outcomes of interest were recurrent instability, reoperation, complications, return to sport (RTS), and American Shoulder and Elbow Surgeons (ASES) score. Independent-samples Results: Overall, 56 patients were included (mean age, 28.4 years). The mean ± SD coracoid length was 21.6 ± 2.4 mm and width 10.0 ± 1.0 mm. Relative to patients with a longer coracoid (≥22 mm; n = 26), patients with a shorter coracoid (mm; n = 30) had similar rates of recurrent instability (shorter vs longer; 6.7% vs 3.8%), complications (10.0% vs 15.4%), reoperation (3.3% vs 7.7%), and RTS (76.5% vs 58.8%) and similar postoperative ASES scores (85.0 vs 81.6) ( Conclusion: Patients undergoing Latarjet coracoid transfer had similar postoperative outcomes regardless of preoperative coracoid dimensions. These findings should be confirmed in a larger cohort before further clinical recommendations are made
