Objectives: To evaluate the (1) 90-day surgical outcomes and (2) 1-year revision rate of robotic versus nonrobotic lumbar fusion surgery. Methods: Patients >18 years of age who underwent primary lumbar fusion surgery at our institution were identified and propensity-matched in a 1:1 fashion based on robotic assistance during surgery. Patient demographics, surgical characteristics, and surgical outcomes, including 90-day surgical complications and 1-year revisions, were collected. Multivariable regression analysis was performed. Significance was set to P < 0.05. Results: Four hundred and fifteen patients were identified as having robotic lumbar fusion and were matched to a control group. Bivariant analysis revealed no significant difference in total 90-day surgical complications (P = 0.193) or 1-year revisions (P = 0.178). The operative duration was longer in robotic surgery (287 + 123 vs. 205 + 88.3, P ≤ 0.001). Multivariable analysis revealed that robotic fusion was not a significant predictor of 90-day surgical complications (odds ratio [OR] = 0.76 [0.32-1.67], P = 0.499) or 1-year revisions (OR = 0.58 [0.28-1.18], P = 0.142). Other variables identified as the positive predictors of 1-year revisions included levels fused (OR = 1.26 [1.08-1.48], P = 0.004) and current smokers (OR = 3.51 [1.46-8.15], P = 0.004). Conclusion: Our study suggests that robotic-assisted and nonrobotic-assisted lumbar fusions are associated with a similar risk of 90-day surgical complications and 1-year revision rates; however, robotic surgery does increase time under anesthesia.

Femoral Neck Fracture Management In The Young Patient: A Case Review, Luis Berrios, Kevin J. Orellana, Michael Lago, Frank Gerold
Research Colloquium
Introduction:The optimal management of femoral neck fractures in the young patient remains controversial. Although there are universally accepted principles, there remains some variability in the optimal timing of surgery and method of fixation. In general, surgery should be performed on an urgent or emergent basis when feasible to decrease peri-operative complications, length of stay, and most importantly the ultimate likelihood of avascular necrosis. However, it is important to note that the preference toward a specific method of fixation remains heterogeneous among orthopedic surgeons.(1)
The purpose of this study is to present our preferred technique for treatment of displaced femoral …

Department of Orthopaedic Surgery Faculty Papers
BACKGROUND: Lateral lumbar interbody fusions (LLIFs) utilize a retroperitoneal approach that avoids the intraperitoneal organs and manipulation of the anterior vasculature encountered in anterior approaches to the lumbar spine. The approach was championed by spinal surgeons; however, general/vasculature surgeons may be more comfortable with the approach.
OBJECTIVE: The objective of this study was to compare short-term outcomes following LLIF procedures based on whether a spine surgeon or access surgeon performed the approach.
MATERIALS AND METHODS: We retrospectively identified all one- to two-level LLIFs at a tertiary care center from 2011 to 2021 for degenerative spine disease. Patients were divided into …

Pedicle Screw-Associated Violation Of The Adjacent Unfused Facet Joint: Clinical Outcomes And Fusion Rates, Nathan J. Sinz, David Hanwuk Kim, Raymond W. Hwang, Gyu-Ho Lee, Kevin Charles Baker, Rick C. Sasso, Daniel K. Park, Jeffrey S. Fischgrund, Ruijia Niu
Conference Presentation Abstracts
INTRODUCTION: Lumbar spine pedicle screws are the most commonly utilized implants for providing immediate spinal stability during fusion surgery. Ideal pedicle screw positioning includes avoiding violation of any adjacent unfused facet joints. Nevertheless, inadvertent screw malposition and screw-associated violation of adjacent facet joints (FJV) remains a potential complication of the procedure regardless of whether surgery is performed in open fashion or with minimally invasive techniques and despite the use of intraoperative imaging or surgical navigation. Given the proximity of the lumbar vertebral pedicle to the proximal facet joint, FJV occurs almost exclusively at the level of the proximal as opposed …

Total Hip Arthroplasty In Young Patients, Aaron G. Chen
Total Hip Arthroplasty In Young Patients, Aaron G. Chen
Electronic Thesis and Dissertation Repository
Total hip arthroplasty (THA) is the gold standard in treatment of hip arthritis yet is often avoided in young patients due to concerns of inferior survivorship. We aim to explore the role of THA in young patients and assess whether these historical concerns are valid in contemporary THA by presenting the results of: (1) a systematic review and meta-analysis of the current literature, (2) a retrospective database review, and (3) a retrospective population-based study. We found excellent long-term survivorship with modern THA in young patients, demonstrating greater than 90% revision-free survival up to 15 years. Factors that may increase risk …

The Outcomes Of Cemented Versus Cementless Total Knee Arthroplasty In Modern Day Patients With Osteoarthritis, Jordan Powelson
The Outcomes Of Cemented Versus Cementless Total Knee Arthroplasty In Modern Day Patients With Osteoarthritis, Jordan Powelson
Capstone Showcase
Osteoarthritis (OA), the degeneration of cartilage and bone, is the most progressive musculoskeletal disease and a leading cause of disability in the United States, affecting over 27 million adults. Although conservative treatments for knee OA are available, total knee arthroplasty (TKA) is the only definitive treatment for end-stage knee OA. For the past several decades, the use of bone cement has been the gold standard for total knee arthroplasty, but the cementless TKA is being revisited as an option as the age of patients seeking TKA decreases and the average BMI increases. This review analyzes and compares the outcomes of …
