The Impact Of Wide-Awake Local Anesthesia No Tourniquet Surgery On Distal Radius Fracture Plating, Michael Carey

Bone Bulletin

Introduction

The surgical technique known as wideawake local anesthesia no tourniquet (WALANT) has been widely used in soft tissue hand procedures since 2005.1 A local surgical field block using lidocaine with epinephrine provides local anesthesia and hemostasis via alpha-1 adrenergic agonism without the need for general anesthesia with a tourniquet. In addition to reducing costs related to general anesthesia (GA), WALANT procedures are suitable for American Society of Anesthesiologists Physical Status Classification 4 (ASA 4) high-risk patients, specifically by eliminating anesthesia risks such as nausea, aspiration, pneumonia, and thromboembolism, all while maintaining or improving clinical outcomes compared with the current …

Suture-Free Nerve Repair In Upper-Extremity Surgery, Adam Gaughan

Bone Bulletin

Introduction

Peripheral nerves have a limited capacity to regenerate.¹ Treating peripheral nerve injuries and the ensuing recovery of sensory and/or motor function are challenging for surgeons due to a number of variables that impact nerve recovery; including, the mechanism of nerve transection, the level or distance of injury relative to the target organ, patient age and comorbidities, and the repair technique employed. Most factors are not modifiable, but repair techniques are modifiable and can have a meaningful impact on outcomes.

Scalpel To Robot To Algorithm: Robotics, Artificial Intelligence, And The Evolution Of Spine Surgery, Mateja Stefanovic

Bone Bulletin

Introduction

The past five decades in spine surgery have seen innovations in pedicle screw fixation, image-guided navigation, and first-generation robotics; each change was confronted with skepticism for uprooting existing paradigms until pushback inevitably yielded progress. Artificial intelligence (AI) and machine learning (ML) feel different in kind. Beyond better instrumentation, they represent entirely new frameworks for processing clinical information at unprecedented scale and speed. A neural network trained on thousands of preoperative records can learn to detect interactions among imaging findings, laboratory indices, functional variables, and comorbidity burden that conventional statistical models are structurally unable to identify.¹˒² Simultaneously, robotic platforms outfitted …

The Changing Value Of Joint Arthroplasty Under The Rvu System, Kiley Hamou

Bone Bulletin

Background and Introduction of Total Knee Arthroplasty

Few procedures in modern medicine illustrate the value of surgical advancement more clearly than total hip and total knee arthroplasty. Over the past several decades, advances in surgical technique, pre-operative management, and postoperative rehabilitation have transformed joint replacement into one of the most successful procedures in medicine. Patient satisfaction rates routinely exceed 90% and millions of individuals regain mobility, independence and quality of life each year through these operations.¹ However, despite this clinical success and societal value, physician reimbursement for joint replacement surgery and many other successful orthopedic procedures has steadily declined. …

Clinical Uncertainty In Digital Monitoring After Shoulder Arthroplasty, Abhimaneu Pandey

Bone Bulletin

Introduction

Wearable sensor technology and smartphone based care platforms have been identified as promising technologies for postoperative care after joint arthroplasties.^1,2 In fact, in lower extremity arthroplasty, these technologies have already demonstrated their effectiveness in a multitude of randomized trials.^1,2 One recent multicenter RCT with 401 patients undergoing primary total knee arthroplasty (TKA) showed that self-directed rehabilitation using a smartwatch and mobile application (mymobility with Apple Watch, Zimmer Biomet) achieved comparable range of motion and patient-reported outcomes measures (PROMs) to standard post-operative rehab without increasing adverse events.¹ Related evidence also indicates that “episode of care” smartphone applications …

Tranexamic Acid In High-Risk Shoulder Arthroplasty Patients: Safety Across Thromboembolic, Cardiac, Renal, And Neurologic Risk Profiles, Tarishi Parmar, Akin Adio, Asim Handy, Mohammad Daher, Alec Kellish, Adam Khan, Joseph A. Abboud

Rothman Institute Papers

INTRODUCTION: Tranexamic acid (TXA) effectively reduces blood loss and transfusion requirements in shoulder arthroplasty. However, concerns regarding thromboembolic, neurologic, cardiac, and renal complications have limited its use in medically high-risk patients. This study evaluated temporal trends and the safety of TXA in high-risk patients undergoing total shoulder arthroplasty (TSA).

METHODS: A retrospective cohort study was conducted using TriNetX, identifying patients who underwent shoulder arthroplasty (2012-2025). Patients were stratified by preexisting high-risk conditions, including prior thromboembolism, renal failure, atrial fibrillation, seizure disorders, and visual disturbances. Within each subgroup, patients receiving TXA were propensity score-matched to those who did not. Perioperative TXA …

Non-Tobacco Nicotine Dependence Is Associated With Increased Complications Following Clavicle Open Reduction Internal Fixation, Akin A. Adio, Rahul K. Goyal, Abby Skiena, Mohammad Daher, John G. Horneff, Hafiz F. Kassam, Brian W. Hill, Joseph A. Abboud

Rothman Institute Papers

BACKGROUND: Tobacco dependence is well established to impair bone healing and increase postoperative complications. However, the independent effects of nicotine, separate from combustion-related factors, remain unclear. This study aimed to evaluate the impact of non-tobacco nicotine dependence (NTND) following open reduction and internal fixation (ORIF) of clavicle fractures, including midshaft and lateral fracture subtypes.

METHODS: A retrospective cohort study was performed using a large national database. Patients undergoing ORIF of clavicle fractures were identified using procedural and diagnostic codes. Patients with non-tobacco nicotine dependence (e.g., vaping, patches, or gum) were identified and propensity score matched to (1) patients without nicotine …

Loss Of Mct1 Mediated Lactate Uptake Causes Delayed Endplate Maturation And Intervertebral Disc Degeneration, Maria Tsingas, Konstantinos Tsingas, Mei Smyers, Wujuan Zhang, Aaron R. Goldman, Eulisa Lawrence, John A. Collins, Makarand V. Risbud

Department of Orthopaedic Surgery Faculty Papers

During skeletal growth, it is thought that the lactate secreted by the glycolytic nucleus pulposus (NP) cells exits the intervertebral disc into circulation via endplates. Our current studies challenge this long-held notion. Mice with early postnatal, endplate, and annulus fibrosus-specific deletion of lactate importer, MCT1, exhibited disc degeneration characterized by NP cell loss and pronounced endplate structural changes. Using metabolic and transcriptomic approaches, we demonstrate that MCT1 loss inhibits endplate chondrocyte differentiation and that lactate serves both as a crucial TCA metabolite and promotes protein and histone lactylation and gene expression. These findings suggest that during skeletal growth, NP-derived lactate …

Medical Student Research Symposium

Title: Comparative Effectiveness of Liposomal Bupivacaine and Regional Nerve Blocks for Analgesia After Total Knee Arthroplasty

Introduction: Liposomal bupivacaine (Exparel) has been adopted in total knee arthroplasty (TKA) as a long-acting local anesthetic. However, its comparative effectiveness against standard regional anesthesia techniques, such as femoral or adductor canal block, remains insufficiently defined. This study evaluates postoperative analgesic utilization following TKA among patients receiving Exparel, regional blocks, or no regional intervention, using matched cohorts from a large national dataset.

Methods: Patients who underwent primary TKA between January 1, 2005 and January 1, 2025 were retrospectively identified from a multi-institutional electronic medical …

Real-World Clinical Outcomes Of Robotic-Assisted Total Knee Arthroplasty: A Propensity-Matched Comparative Study, Hassan Yassine, Amir Ghafarian, Jawad Saad, Abdel Kareem Hilo, Muaaz Wajahath, Khaled Saleh

Medical Student Research Symposium

Background:

Robotic-assisted total knee arthroplasty (RA-TKA) is increasingly utilized to improve component alignment and soft-tissue balance, yet its impact on clinically meaningful outcomes in large real-world populations remains uncertain. Although prior studies demonstrate improved radiographic accuracy, whether robotic assistance reduces postoperative complications, opioid utilization, or midterm mechanical failure has not been established at scale.

Methods:

We conducted a retrospective, propensity-matched cohort study using the TriNetX US Collaborative Network to identify adults undergoing primary TKA from 2018–2023. Robotic-assisted procedures were defined by CPT 27447 with concurrent robotic navigation codes. Propensity score matching (1:1) was performed to balance demographics and comorbidities, yielding …

A Tactile Trans-Flexor Carpi Radialis Surface Landmark Technique For Median Nerve Local Injection: A Cadaveric Study, Clark Chen, Keenan Sobol, Connor Hickey, Duncan Vannest, John Ibrahim, James Raphael

Einstein Health Papers

PURPOSE: Median nerve (MN) block under local anesthesia at the wrist is commonly performed but can be limited by anatomic variation, particularly absence of the palmaris longus tendon. This study investigates a novel trans-flexor carpi radialis (trans-FCR) technique for MN anesthesia that uses the flexor carpi radialis (FCR) tendon as a consistent surface landmark.

METHODS: Fourteen fresh frozen upper extremity cadaver specimens were used. A 25-gauge needle was inserted through the FCR sheath approximately 4 cm proximal to the wrist crease in a transverse fashion, angled approximately 0° to the vertical and parallel to the wrist crease. The trans-FCR technique …

From Confirmation To Guidance: Making The Case For Intraprocedural Pocus As The Next Developmental Step In Ultrasound-Supported Shoulder Reduction A Conceptual Practice Proposal And Research Agenda, James Espinosa

Rowan-Virtua Research Day

Point-of-care ultrasound (POCUS) is well established for the diagnosis of shoulder dislocation and for the confirmation of successful reduction. However, its role during the reduction maneuver itself remains under-described. This conceptual practice proposal argues that intraprocedural POCUS represents the logical next developmental step in ultrasound-supported shoulder reduction. By introducing real-time visualization of humeral head translation during reduction attempts, clinicians may identify ineffective vectors earlier, adjust technique midstream, and potentially reduce repeated attempts or escalation of procedural sedation. This work does not present outcome data but instead proposes a practical framework, workflow model, and research agenda for intraprocedural implementation. Future study …

Department of Orthopaedic Surgery Faculty Papers

BACKGROUND: in 2020, the accreditation Council for Continuing Medical education (aCCMe) released the Standards for Integrity and Independence in Accredited Continuing Medical Education, effective january 1, 2022, to ensure that accredited activities are accurate, balanced, evidence-based, and clearly separated from marketing and sales. although these aims are broadly supported, implementation may have unintended consequences in procedure-intensive specialties such as spine surgery, where surgeon–industry collaboration often drives device innovation, clinical trials, and dissemination of new techniques.

OBJECTIVE: To examine how current interpretations of ACCME eligibility and financial-relationship standards may affect continuing medical education in spine surgery and to propose practical adaptations …

Modeling Structural Support To Facilitate Novel Treatments Of Degenerative Disc Disease, Jose Luis Calderon

Poster Presentations

Over 600 million people worldwide suffered from low back pain in 2020, with projections for 2050 being over 800 million [1]. Annual costs associated with low back pain total over 450 billion dollars in the US alone [2]. This research serves as a proof-of-concept for the use of structural supports to facilitate intervertebral disc healing. This treatment would involve the implementation of these supports along with existing injection treatments to promote regeneration. In both models, along with the combined model, the ability for these supports to alleviate intervertebral disc height loss is shown. This indicates that these supports would serve …
