Late Removal Of Titanium Hardware From The Elbow Is Problematic, Abdo Bachoura, Ruriko Yoshida, Christian Lattermann, Srinath Kamineni

Orthopaedic Surgery and Sports Medicine Faculty Publications

A retrospective review of 21 patients that underwent bone screw removal from the elbow was studied in relation to the type of metal, duration of implantation, and the location of the screws about the elbow. Screw failure during extraction was the dependent variable. Five of 21 patients experienced hardware failure during extraction. Fourteen patients had titanium alloy implants. In four cases, titanium screws broke during extraction. Compared to stainless steel, titanium screw failure during removal was not statistically significant (P = 0.61). Screw removal 12 months after surgery was more likely to result in broken, retained screws in general …

However, the effect of early surgical decompression in patients with acute SCI remains uncertain. Our objective was to evaluate the relative effectiveness of early (injury) versus late (≥ 24 hours after injury) decompressive surgery after traumatic cervical SCI.

METHODS: We performed a multicenter, international, prospective cohort study (Surgical Timing In Acute Spinal Cord Injury Study: STASCIS) in adults aged 16-80 with cervical SCI. Enrolment occurred between 2002 and 2009 at 6 North American centers. The primary outcome was ordinal change …

Minimal Invasive Decompression For Lumbar Spinal Stenosis., Victor Popov, David G Anderson

Department of Orthopaedic Surgery Faculty Papers

Lumbar spinal stenosis is a common condition in elderly patients and may lead to progressive back and leg pain, muscular weakness, sensory disturbance, and/or problems with ambulation. Multiple studies suggest that surgical decompression is an effective therapy for patients with symptomatic lumbar stenosis. Although traditional lumbar decompression is a time-honored procedure, minimally invasive procedures are now available which can achieve the goals of decompression with less bleeding, smaller incisions, and quicker patient recovery. This paper will review the technique of performing ipsilateral and bilateral decompressions using a tubular retractor system and microscope.

Development Of An Ankle Function Model, Kelli R. Snyder

Dissertations and Theses @ UNI

Lateral ankle sprains (LAS) represent the most common orthopedic injury treated by athletic trainers, yet there is no consensus regarding the measurement of the effectiveness of care (e.g. outcomes). Further compounding this problem is the repetitive nature of LAS, often referred to as "functional" or "chronic" ankle instability (FAI, CAI, respectively). Although a common entity in practice and research, FAI is inconsistently defined and assessed. Essentially, athletic trainers are neglecting to address one of the most important issues identified in their profession (outcomes) for the most common injury for which they provide care (LAS). Therefore, the purpose of this research …

Molecular Diagnostics In Periprosthetic Joint Infection., Javad Parvizi, Lesley Walinchus, Bahar Adeli

Department of Orthopaedic Surgery Faculty Papers

Periprosthetic joint infection (PJI) is a significant and costly challenge to the orthopedic community. The lack of a gold standard for diagnosis remains the biggest obstacle in the detection and subsequent treatment of PJI. Molecular markers in the serum and joint fluid aspirate hold immense promise to enhance the development of a firm diagnostic criterion. The primary goal is one marker with high sensitivity and specificity. Here, we review our current research efforts in the field of molecular markers: C-reactive protein, erythrocyte sedimentation rate, white blood cells, and leukocyte esterase. Each marker has been studied to determine its sensitivity, specificity, …

Department of Orthopaedic Surgery Faculty Papers

ABSTRACT: INTRODUCTION: Back pain, a significant source of morbidity in our society, is related to the degenerative changes of the intervertebral disc. At present, the treatment of disc disease consists of therapies that are aimed at symptomatic relief. This shortcoming stems in large part from our lack of understanding of the biochemical and molecular events that drive the disease process. The goal of this study is to develop a model of early disc degeneration using an organ culture. This approach is based on our previous studies that indicate that organ culture closely models molecular events that occur in vivo in …

Isolated Cryptococcal Osteomyelitis In An Immunocompetent Patient, Irfan Qadir, Farheen Ali, Umair Zafar Malik, Masood Umer

Department of Surgery Docs

bstract

Cryptococcosis is a rare infection in HIV-negative individuals. While the lungs and the central nervous system are most commonly infected, skeletal cryptococcosis is uncommon and isolated osteomyelitis due to Cryptococcus neoformans is quite rare. To our knowledge, only 47 cases of isolated cryptococcal osteomyelitis have been reported from 1974 to 2005. We report a case of isolatedcryptococcal osteomyelitis in an immunocompetent patient, who received 12 weeks of fluconazole with complete recovery.

Classification And Treatment Of Proximal Humerus Fractures: Inter-Observer Reliability And Agreement Across Imaging Modalities And Experience., Abtin Foroohar, Rick Tosti, John M Richmond, John P Gaughan, Asif M Ilyas

Rothman Institute Papers

SUMMARY: Proximal humerus fractures (PHF) are common injuries, but previous studies have documented poor inter-observer reliability in fracture classification. This disparity has been attributed to multiple variables including poor imaging studies and inadequate surgeon experience. The purpose of this study is to evaluate whether inter-observer agreement can be improved with the application of multiple imaging modalities including X-ray, CT, and 3D CT reconstructions, stratified by physician experience, for both classification and treatment of PHFs.

METHODS: Inter-observer agreement was measured for classification and treatment of PHFs. A total of sixteen fractures were imaged by plain X-ray (scapular AP and lateral), CT …

Systematically Controlling For The Influence Of Age, Sex, Hertz And Time Post-Whole-Body Vibration Exposure On Four Measures Of Physical Performance In Community-Dwelling Older Adults: A Randomized Cross-Over Study, Harold L. Merriman, C. Jayne Brahler, Kurt Jackson

Physical Therapy Faculty Publications

Though popular, there is little agreement on what whole-body vibration (WBV) parameters will optimize performance. This study aimed to clarify the effects of age, sex, hertz, and time on four physical function indicators in community-dwelling older adults (N = 32). Participants were exposed to 2 minutes WBV per session at either 2 Hz or 26 Hz, and outcome measures were recorded at 2-, 20-, and 40-minute post-WBV. Timed get-up-and-go and chair sit-and-reach performances improved post-WBV for both sexes, were significantly different between 2 Hz and 26 Hz treatments (P ≤ 0.05), and showed statistically significant interactions between age and gender …

Femoroacetabular Impingement: Saving The Joint, Ronald Huang, Javad Parvizi

Department of Orthopaedic Surgery Faculty Papers

Many factors have been linked to the development of osteoarthritis (OA) of the hip, but often, cases are still considered “idiopathic.” Femoroacetabular impingement (FAI) has been suggested as a possible etiologic factor for the otherwise “idiopathic” cases. It is theorized that the subtle morphologic abnormalities seen at the head-neck junction and acetabulum in FAI may lead to labral tears, chondral damage, and subsequent progression of OA. Prevalence of FAI has been suggested to be as high as 14% in the general population. It often presents in young active patients that subject their hip joint to repetitive micro trauma associated with …

The Use Of Motion Analysis Technology As An Alternative Means Of Assessing Spinal Deformity In Patients With Adolescent Idiopathic Scoliosis, Matthew J. Solomito

Master's Theses

Adolescent Idiopathic Scoliosis (AIS) is a three dimensional deformity of the spine that causes abnormal curvatures in the coronal and sagittal planes and abnormal vertebral rotations. The gold standard for diagnosing and tracking the progression of the deformity is through the use of repeated radiography and a patient can receive upwards of fifteen radiographic series over the course of treatment, which exposes this population to an increased risk of radiation-dependent complications.

This thesis presents the necessary calculations and the marker set required to make the motion capture technology a viable alternative to radiographs, in an effort to reduce the patient’s …

Use Of Tranexamic Acid Is A Cost Effective Method In Preventing Blood Loss During And After Total Knee Replacement, Yasir Jamal Sepah, Masood Umer, Tashfeen Ahmad, Faria Nasim, Muhammad Umer Chaudhry, Muhammad Umar

Section of Orthopaedic Surgery

Background & Purpose: Allogenic blood transfusion in elective orthopaedic surgery is best avoided owing to its associated risks. Total knee replacement often requires blood transfusion, more so when bilateral surgery is performed. Many strategies are currently being employed to reduce the amount of peri-operative allogenic transfusions. Anti-fibrinolytic compounds such as aminocaproic acid and tranexamic acid have been used systemically in perioperative settings with promising results. This study aimed to evaluate the effectiveness of tranexamic acid in reducing allogenic blood transfusion in total knee replacement surgery.
Methodology: This was a retrospective cohort study conducted on patients undergoing total knee replacement during …

Potent Inhibition Of Heterotopic Ossification By Nuclear Retinoic Acid Receptor-Γ Agonists., Kengo Shimono, Wei-En Tung, Christine Macolino, Amber Hsu-Tsai Chi, Johanna H Didizian, Christina Mundy, Roshantha A Chandraratna, Yuji Mishina, Motomi Enomoto-Iwamoto, Maurizio Pacifici, Masahiro Iwamoto

Department of Orthopaedic Surgery Faculty Papers

Heterotopic ossification consists of ectopic bone formation within soft tissues after surgery or trauma. It can have debilitating consequences, but there is no definitive cure. Here we show that heterotopic ossification was essentially prevented in mice receiving a nuclear retinoic acid receptor-γ (RAR-γ) agonist. Side effects were minimal, and there was no significant rebound effect. To uncover the mechanisms of these responses, we treated mouse mesenchymal stem cells with an RAR-γ agonist and transplanted them into nude mice. Whereas control cells formed ectopic bone masses, cells that had been pretreated with the RAR-γ agonist did not, suggesting that they had …

Short-Term And Long-Term Effects Of Orthopedic Biodegradable Implants, Ami R. Amini, James S. Wallace, Syam P. Nukavarapu

Articles - Patient Care

Presently, orthopedic and oral/maxillofacial implants represent a combined $2.8 billion market, a figure expected to experience significant and continued growth. Although traditional permanent implants have been proved clinically efficacious, they are also associated with several drawbacks, including secondary revision and removal surgeries. Non-permanent, biodegradable implants offer a promising alternative for patients, as they provide temporary support and degrade at a rate matching tissue formation, and thus, eliminate the need for secondary surgeries. These implants have been in clinical use for nearly 25 years, competing directly with, or maybe even exceeding, the performance of permanent implants. The initial implantation of biodegradable …

Knee Range Of Motion: Reliability And Agreement Of 3 Measurement Methods, Paul G. Peters, Michael A. Herbenick, Philip A. Anloague, Ronald J. Markert, L. Joseph Rubino

Physical Therapy Faculty Publications

We conducted a study to compare 3 methods of measuring knee range of motion: visual estimation by physicians, hand goniometry by physical therapists, and radiographic goniometry. We hypothesized that reliability would be high within and across all techniques. We found intrarater and interrater reliability to be satisfactory for visual estimation, hand goniometry, and radiographic goniometry. Interrater reliability across methods did not agree satisfactorily. Between-methods differences in estimating knee range of motion may result from variations in technique among physicians and physical therapists.
