Burden Of Periprosthetic Joint Infection And Its Treatment On Kidney Function

Rothman Institute Conference Posters

Introduction:

Patients with periprosthetic joint infection (PJI) are subjected to several potentially nephrotoxic conditions such as acute and chronic systemic inflammatory reactions, multiple surgical procedures and noxious antibiotics. This study aims to investigate 1) the incidence and severity of kidney injury in patients undergoing surgical treatment for PJI, 2) whether the number of surgeries affects renal function in PJI patients and 3) the potential risk factors for kidney injury.

Low Dose Aspirin: An Effective Chemoprophylaxis For Preventing Venous Thromboembolic Events, Javad Parvizi, Md, Frcs, Antonia F. Chen, Md, Mba, Camilo Restrepo, Md, Ronald Huang, Md, Jenny Cal, Bs, William J. Hozack, Md, Jess H. Lonner, Md

Rothman Institute Conference Posters

The available guidelines, endorsed by Surgical Care Improvement Project (SCIP), have advocated that aspirin (ASA) is a safe and eff­ective strategy for venous thromboembolic events (VTE) prophylaxis following total joint arthroplasty (TJA). The optimal dose of aspirin for this purpose is not known. The first guidelines for prevention of VTE that were issued by the American Academy of Orthopedic Surgeons recommended 325 mg Bis in die (twice a day) (bid) for this purpose with the recommendation having a 1C grade (little evidence to support the recommendation). It is known that platelet aggregation inhibition occurs at lower doses. Traditionally, ASA 81mg …

Red Cell Distribution Width: An Unacknowledged Predictor Of Mortality And Length Of Stay Following Revision Arthroplasty, Pouya Alijanipour, Md, Snir Heller, Md, Fatih Kucukdurmaz, Md, Benjamin Zmistowski, Md, Maryam Rezapoor, Ms, Javad Parvizi, Md, Frcs

Rothman Institute Conference Posters

Introduction

Red blood cell distribution width (RDW), a measure of variability in size of circulating erythrocytes, is routinely reported in complete blood cell analysis, and together with mean cell volume (MCV) has conventionally been used to distinguish the cause of anemia. It is calculated by (Standard deviation of MCV÷ mean MCV) x 100, with normal range being 11.5%-14.5%. Several recent publications have described RDW as an independent predictor of adverse outcome and mortality in patients with different underlying medical conditions such as acute and chronic heart failure, peripheral artery disease, chronic pulmonary disease and acute kidney injury1. The purposes of …

Radiation Exposure To The Eye With Mini C-Arm Use During Hand Surgery, Mark L. Wang, Md, Phd, C. Edward Hoffler, Md, Phd, Frederick E. Liss, Md, Asif Ilyas, Md, Charles Leinberry, Md, Pedro Beredjiklian, Md

Rothman Institute Conference Posters

Introduction:

Fluoroscopic radiation exposure is a potential occupational health risk to the Hand Surgeon, given operator proximity and the relative lack of eye shielding. The association of eye radiation exposure and the early development of cataracts have been previously reported. Mini C-arm fluoroscopy is commonly utilized during routine Hand Surgery. At present, the amount of radiation exposure to the eye, associated with the routine use of mini C-arm fluoroscopy, is unknown, thus warranting further investigation. The purpose of this study is to test the hypothesis that eye radiation exposure, sustained during routine mini C-arm use, does not exceed that of …

Long Term Follow-Up Of A Successful Lower Limb Replantation In A 3-Year-Old Child, Akbar Jaleel Zubairi, Pervaiz Mahmood Hashmi

Section of Orthopaedic Surgery

Replantation of the lower extremity has controversial indications but nevertheless it may be considered in carefully selected patients who present early and are expected to show good functional recoveries. Here we present a successful replantation in a 3-year-old boy who has made excellent recovery with no functional deficit evident at 12 years of follow-up. He sustained a traumatic amputation at the level of distal tibia when he fell of a "Qing Qi" (motorcycle rickshaw). Replantation was attempted at 8 hours cold ischemia time with the tibia shortened 4cm and all tendons, vessels, and nerves repaired. Patient required a second procedure …

Rotational Alignment In Medial Unicompartmental Knee Arthroplasty: Comparison Of Anatomic Landmarks, Glenn J. Kerr, Md, Patrick O'Toole, Md, Eddie Wu, Do, Jess H. Lonner, Md

Rothman Institute Conference Posters

Introduction:

The landmarks used for tibial component rotation in total knee arthroplasty (TKA) and medial unicompartmental knee arthroplasty (UKA) may differ, utilizing the medial edge of the tibial tubercle and the medial edge of the tibial spine, respectively. However, some surgeons reference from the medial edge of the tibial tubercle in UKA. Use of the tibial tubercle to determine orientation of the sagittal cut in medial UKA can result in external rotation of the tibial component, leading to rotational mismatch between the femoral and tibial components, potential disruption of the ACL and tibial component undersizing. The purpose of this study …

The Patellar Tendon Can Cause External Tibial Component Malrotation In Lateral Unicondylar Knee Arthroplasty, Glenn J. Kerr, Md, Patrick O'Toole, Md, Eddie Wu, Do, Jess H. Lonner, Md

Rothman Institute Conference Posters

Introduction:

The optimal rotational axis of the tibial component in lateral unicompartmental knee arthroplasty (UKA) should be aligned parallel to the lateral tibial spine. However, the relatively lateral positions of the tibial tubercle and patellar tendon make the sagittal tibial cut in lateral UKA difficult and commonly predisposes to inadvertent external rotation of the tibial component. The purpose of this study was to quantify the potential rotational impact that occurs when aligning the anterior edge of the sagittal tibial cut with the lateral edge of the patellar tendon in lateral UKA.

Matzon, Md, Charles Leinberry, Md, Mark L. Wang, Md, Phd, Christopher Jones, Md, William Kirkpatrick, Md, Asif M Ilyas, Md

Rothman Institute Conference Posters

Introduction:

Trigger fi­nger (TF) is one of the most common conditions treated by hand surgeons with a lifetime risk up to 10% in patients with diabetes. If conservative management fails, surgical treatment is undertaken, with or without sedation and a tourniquet, via a small incision to release the A1 pulley. A number of local anesthetics are readily available including Lidocaine, Ropivacaine and Marcaine as well as encapsulated formulations thereof such as Exparel. Since it’s approval in 2011, there have been numerous reports of successfully achieving prolonged pain relief with locally injected Exparel after various procedures, but to the best of …

Rothman Institute Conference Posters

Introduction:

• Driving restrictions after total hip arthroplasty (THA) can be inconvenient and burdensome for patients.
• When patients may safely be allowed to drive remains controversial.
• Most studies recommend 6 weeks but recent advances in surgical approach, pain management and rapid recovery may have changed this time frame.
• The purpose of this study was to prospectively evaluate driving safety after THA through brake reaction time.

Aspirin May Be Adequate For Venous Thromboembolic Event Prophylaxis After Revision Hip And Knee Arthroplasty, Greg K. Deirmengian, Md, Snir Heller, Md, Eric B. Smith, Md, Mitchell Maltenfort, Phd, Javad Parvizi, Md, Frcs

Rothman Institute Conference Posters

Introduction:

The optimal prophylaxis for prevention of venous thromboembolic events (VTE) after total hip arthroplasty (THA) and total knee arthroplasty (TKA) remains unknown.(1) Current studies focus on primary arthroplasty and there are little to no data on the ideal prophylaxis for VTE following revision arthroplasty.(2) Revision surgery, due to its complexity, longer operative time, higher risk of bleeding and infection diff­ers from primary arthroplasty.(3) The objective of this study was to evaluate whether aspirin, known to be e­ffective for prevention of VTE after primary arthroplasty, is also e­ffective against such events following revision THA and TKA.

Anterior Cruciate Ligament Reconstruction With Bone-Patellar Tendon-Bone Autograft Versus Allograft In Young Patients, Alfred W. Atanda, Daniel F. O'Brien, Matthew J. Kraeutler, Russell R. Flato, Matthew R. Salminen, Kevin Henrichsen, Patrick Kane, Christopher Dodson, Steven B. Cohen, Michael G. Ciccotti

Rothman Institute Papers

Objectives: Traditionally, bone-patella tendon-bone (BTB) autograft has been the gold standard graft choice for younger, athletic patients requiring ACL reconstruction. However, donor site morbidity, post-operative patella fracture, and increased operative time have led many surgeons to choose BTB allograft for their reconstructions. Opponents of allografts feel that slower healing time, higher rate of graft failure, and potential for disease transmission makes them undesirable graft choices in athletic patients. The purpose of this study is to evaluate the clinical outcomes, both subjective and objective, of young patients that who have undergone either BTB autograft or allograft reconstructions with a minimum of …

Biological Response To Prosthetic Debris., Diana Bitar, Javad Parvizi

Rothman Institute Papers

Joint arthroplasty had revolutionized the outcome of orthopaedic surgery. Extensive and collaborative work of many innovator surgeons had led to the development of durable bearing surfaces, yet no single material is considered absolutely perfect. Generation of wear debris from any part of the prosthesis is unavoidable. Implant loosening secondary to osteolysis is the most common mode of failure of arthroplasty. Osteolysis is the resultant of complex contribution of the generated wear debris and the mechanical instability of the prosthetic components. Roughly speaking, all orthopedic biomaterials may induce a universal biologic host response to generated wear débris with little specific characteristics …
