The Utility Of The Axillary Shoulder Radiograph In The Management Of Clavicle Fractures, Stephen Bowen, Ryan Tantoe, Daniel Botros, Samer Al-Humadi, Nicholas Tsouris, Nicholas Divaris

Stony Brook Orthopaedic and Musculoskeletal Journal

Background: Prior literature is mixed on the necessity of an axillary shoulder radiograph in the setting of presumably isolated clavicle fractures, with some authors endorsing its need for any shoulder girdle trauma and others stating it is unnecessary. However, no studies to date have specifically evaluated this.

Hypothesis: We hypothesize that an axillary shoulder radiograph will offer no management changing information in the setting of clavicle fractures.

Methods: Ninety-five patients presented for follow-up for management of a clavicle fracture. Analysis was performed to determine if the axillary view was useful based on the discovery of a glenohumeral dislocation or a …

Suture Tape Stabilization Of The Distal Ulna Following Darrach Procedure. A Biomechanical Study, Miles S. Parsons, Evan C. Olsen, David E. Komatsu, Samantha Muhlrad

Stony Brook Orthopaedic and Musculoskeletal Journal

Introduction: The Darrach procedure (complete resection of distal ulna) is commonly used for definitive treatment of end- stage distal radioulnar joint (DRUJ) arthritis. This resection alone often results in treatment failure due to ulnar stump instability in a dorsal-palmar direction and ulnar convergence. Modified Darrach procedures with tenodesis have improved outcomes, but none have completely resolved these issues. Thus, we propose a novel technique of fixation via an internal brace.

Purpose: To evaluate stability and degree of dorsal-palmar displacement with an internal brace fixation (IBF) versus a modified extensor carpi ulnaris tenodesis (ECUT) following a Darrach procedure.

Methods: We tested …

Next, a 1.5-cm anterolateral portal to the radiocapitellar joint was made and tagged with heavy suture and passed through the lateral elbow wound, with the elbow and forearm in an extended, supinated position. We then dissected out neurovascular structures around the elbow and measuring …

Non-Weightbearing In Cam Boots After Foot/Ankle Fracture Fixation: Are Patients Compliant?, Amos Z. Dai, Michelle Regan, Megan Paulus

Stony Brook Orthopaedic and Musculoskeletal Journal

Background: The controlled ankle motion (CAM) boot has become an integral part of the management of both operative and nonoperative foot and ankle conditions. Similar to casts, CAM boots are used to immobilize the foot and ankle after injury or surgery. However, unlike casts, CAM boots can be readily removed for showering and range of motion (ROM) exercises. While CAM boots are well-designed for ambulation and are frequently utilized in early weightbearing (WB) and early ROM protocols, their usage in non-weightbearing (NWB) protocols is less clear.

Purpose: The purpose of the current study is to determine the patient compliance rate …

Methods: We queried the American College of Surgeons National Surgical Quality Improvement Program database for all patients who underwent ARCR from 2015 to 2017. Patients were stratified into 3 cohorts according to their body mass index (BMI). Patients with a BMI < 30 kg/m2 were placed in the non-obese cohort, patients with a BMI between 30 and 40 kg/m2 were placed in the obese cohort, and patients with a BMI > 40 kg/m2 were placed in the morbidly obese cohort. Postoperative complications within 30 days of the procedure were collected. Multivariate logistic regression was used to investigate the relationship between increasing levels …

Reconstructionof Congenital Arhinia With Stereolithography, Kelly Spiller, Kaitlynne Pak, Lucas M. Harrison, Spencer Anderson, Steven Schmidt, Salim Mancho

Medical Student Research Symposium Abstracts and Posters

Complete congenital arhinia is a rare defect of embryogenesis leading to the absence of the external nose and nasopharyngeal airway. In this study, we report our novel multi-staged reconstructive approach of congenital arhinia in addition to literature review. Reconstruction was achieved via several spaced operations. A nasal methyl methacrylate prosthesis was first created from a stereolithographic model for use as a temporary prosthesis and tissue expander. Lefort 1 osteotomy with cannulization was then utilized for midface advancement and nasopharyngeal airway formation. External nasal framework was constructed with bilateral conchal bowl cartilage and rib osteocartilagenous grafts. The patient was overall pleased …

Are Radiographs Over-Utilized In Pediatric Orthopaedic Emergency Room Care?, Brian Lynch, Stephen Bowen, David E. Komatsu, Wesley Carrion

Stony Brook Orthopaedic and Musculoskeletal Journal

Background: There is an estimated $760 to $935 billion in annual cost of waste in the United States healthcare system. $12.8 to $28.6 billion is attributed to wasteful studies/treatments. In an effort to examine current waste in our institution, we examined the use of radiographs in orthopedic patients evaluated in our pediatric emergency department (ED). The pediatric population is largely unable to make decisions for themselves and thus are susceptible to unneeded studies.

Hypothesis/Purpose: We propose that there is a significant amount of waste, in regard to: time, cost, and resources in the ED. Additionally, we believe that unnecessary studies …

Is There A Role For Ct Pan-Scans In The Initial Work-Up Of Fragility Fracture Patients?, Eric Lepkowsky, Trevor Simcox, Hunter Rogoff, Shahidul Islam, Omid Barzideh

Stony Brook Orthopaedic and Musculoskeletal Journal

Background: CT pan-scans have become increasingly commonplace as part of the initial diagnostic work-up for patients sustaining traumatic injuries. They have proven effective in improving diagnostic accuracy in those with high energy mechanisms of injury. However, the utility of pan-scans in the geriatric population sustaining low energy traumatic injuries remains unproven. There is no study that assesses the usefulness of CT pan-scans in patients who sustain injuries related to osteoporosis, also known as fragility fractures.

Methods: A retrospective review was conducted of patients who sustained a fragility fracture at a Level 1 trauma center over a 15-month period. Patients underwent …

Effects Of Alcohol Use On Total Knee Arthroplasty Patient Osteoarthritis Severity, Preoperative Pain Scores, And Postoperative Range Of Motion: A Retrospective Study, Christopher Ruland, Samir Baig, Zach Warheit, David E. Komatsu, James Nicholson

Stony Brook Orthopaedic and Musculoskeletal Journal

Introduction: Despite the prevalence of significant alcohol use, the effect of alcohol consumption on patients undergoing total knee arthroplasty (TKA) is poorly understood. Other forms of substance abuse, such as narcotic dependence, decrease patient pain tolerance and increase self-reported pain scores, while excessive alcohol consumption has been associated with adverse outcomes following other elective surgical procedures. In the context of TKA, perception of pain is also likely linked to the ability to achieve functional postoperative range of motion (ROM), one of the most important predictive indicators of patient satisfaction. It is not well understood whether heavy alcohol users who are …

The prevention of infection is the single most important goal, influencing perioperative care of patients with open fractures. Using data from 2,500 participants with open fracture wounds enrolled in the Fluid Lavage of Open Wounds trial, we conducted a multivariable analysis to determine the factors that are associated with infections 12 months postfracture. Methods: Eighteen predictor variables were identified for infection a priori from baseline data, fracture characteristics, and surgical data from the Fluid Lavage of Open Wounds trial. Twelve predictor variables were identified for deep infection, which included …

Inadvertent Radial Head Inversion During Closed Reduction Of A Pediatric Radial Neck Fracture, Zachary J. Sirois, Sarah Kreul, Craig F. Shank

Orthopaedic Surgery Faculty Publications

Management of displaced pediatric radial neck fractures can be fraught with challenges. This unique case presents an 11-year-old female with a Salter-Harris type II radial neck fracture and how her radial head overturned 180° with the articular surface facing the radial shaft rather than the capitellum during closed manipulation under anesthesia. The malreduction subsequently required open reduction and highlights the importance of a careful stepwise approach to managing markedly displaced radial neck fractures. After closed reduction, meticulous assessment of intraoperative imaging when determining proper alignment is of the utmost importance as a result of the transverse nature of Salter-Harris type …

Evaluation Of Tissue-Engineered Tendon Enthesis Polymer Constructs, Joshua A. Bundy Bs, Mary Beth Wade Phd, Hitomi Nakao Md, Phillip Mcclellan Phd, Qing Yu Phd, Robin Jacquet-Childs Ms, William J. Landis Phd

Williams Honors College, Honors Research Projects

Both scientists and clinicians have proposed tissue engineering as the future of medicine. The possibilities for tissue engineering, that is, fabrication of tissues and organs in the laboratory and their translation to patients, appear to be endless, and many believe that this new approach in medicine will result in abolishing many common ailments, injuries, and congenital defects. Injuries to a tendon enthesis, the normal tissue connection between tendon and bone, are of particular concern to clinicians because of their frequency and failure to repair as a result of surgery. While these injuries may not be life threatening, they can certainly …
