Short-Term Pain Outcomes In Robotic Versus Manual Total Hip Arthroplasty, Brienne Paradis OMS3, Andrea M. Bodine MD 2022 University of New England

Short-Term Pain Outcomes In Robotic Versus Manual Total Hip Arthroplasty, Brienne Paradis Oms3, Andrea M. Bodine Md

Advances in Clinical Medical Research and Healthcare Delivery

Background: Four-hundred-fifty-thousand patients annually undergo total hip arthroplasty (THA) in the United States. THA has been shown to alleviate pain, restore function, and improve quality of life. Manual implant postoperative complications have led to a need for more advanced technology. Robotic assisted THA has the potential for greater accuracy in component positioning compared to manual. Comparing robotic and manual THA, significant differences have been shown in hip-specific functional outcomes, component positioning, complications, and patient-centered outcomes. The effects of these techniques on differences from baseline pain have yet to be investigated.

Methods: A retrospective review of the Berkshire Medical Center electronic ...


Review: Management Of Midshaft Clavicle Fractures In Adolescents , Matthew B. Holloway 2022 University of Tennessee Health Science Center

Review: Management Of Midshaft Clavicle Fractures In Adolescents , Matthew B. Holloway

Longitudinal Scholar's Project

Clavicle fractures are common injuries that occur across all age ranges, but are largely seen in young, active males. The majority of these fractures (70-80%) occur in the midshaft of the clavicle. The purpose of this review was to compare non-operative treatment to operative treatment of midclavicular fractures and determine whether treatment for adolescent clavicle fractures more closely aligns with pediatric or adult management. Adolescent clavicle fractures are increasingly treated with open reduction and internal fixation, especially in the 15 to 19 age group. Nevertheless, there remains a lack of high-level studies comparing outcomes of operative and conservative treatment specifically ...

Study Design: Cohort study; Level of evidence, 3.

Methods: Workers' compensation patients who underwent complete proximal hamstring avulsion open repair between 2010 and 2019 were identified (WC group). A control group was matched by age (±3 years), sex, and body mass index (BMI; ±3). Demographics ...


Biomechanical Characterization Of Semi-Rigid Constructs And The Potential Effect On Proximal Junctional Kyphosis In The Thoracic Spine, Chloe Cadieux 2022 The University of Western Ontario

Biomechanical Characterization Of Semi-Rigid Constructs And The Potential Effect On Proximal Junctional Kyphosis In The Thoracic Spine, Chloe Cadieux

Electronic Thesis and Dissertation Repository

Long spinal fusions are the mainstay of treatment in adult spinal deformity; however, proximal junctional kyphosis (PJK) is a common and potentially catastrophic complication that can occur following this procedure. It has been hypothesized that using semi-rigid constructs at the superior aspect of the instrumentation may decrease this complication. The objective of this thesis was to determine if there is a biomechanical advantage between various semi-rigid constructs utilized in long spinal fusions to help decrease the risk of PJK. Nine human cadaveric spines (T1 – T12) instrumented with the standard all-pedicle-screw construct (APS) were compared to various semi-rigid constructs including sublaminar ...

Modic changes (MCs) are believed to be potential pain generators in the lumbar and cervical spine, but it is currently unclear if their presence affects postsurgical outcomes. We performed a systematic review in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. All studies evaluating cervical or lumbar spine postsurgical outcomes in patients with documented preoperative MCs were included. A total of 29 studies and 6013 patients with 2688 of those patients having preoperative MCs were included. Eight included studies evaluated cervical spine surgery, eleven evaluated lumbar discectomies, nine studied lumbar fusion surgery, and three assessed ...


Total Joint Implant Alloy Oxide Layer Cell-Induced Damage, Chandler K. Sears 2022 University of Tennessee Health Science Center

Total Joint Implant Alloy Oxide Layer Cell-Induced Damage, Chandler K. Sears

Longitudinal Scholar's Project

Cobalt-Chromium alloy is commonly used in total joint arthroplasty (TJA). Several studies have investigated evidence of inflammatory-cell-induced-corrosion (ICIC) causing pitting in TJA retrieved implants. Others have determined that placing orthopedic alloys into lower pH solutions will increase the rate of corrosion. We have determined that electrochemical potential and corrosion rates of human knee synovial fluid show a variation greater than an order of magnitude. This means there is going to be a significant variation between a patient’s local environment of the TJA implant and may affect how macrophages interact with alloy oxide layers. Knee disability can be quantified by ...

Household Transmission Of Group A Streptococcus Necrotizing Fasciitis., Michael Markowitz, Stephanie Kwan, Jonas Matzon 2022 Rowan University

Household Transmission Of Group A Streptococcus Necrotizing Fasciitis., Michael Markowitz, Stephanie Kwan, Jonas Matzon

Department of Orthopaedic Surgery Faculty Papers

A healthy 40-year-old woman was diagnosed with necrotizing fasciitis 2 days after her husband's death from the same infectious process. Prompt identification and immediate surgical intervention prevented a similar result in this patient. Additional investigation into both patients' medical records found the inciting organism to be group A streptococcus. Although the exact mechanism of inoculation is unknown, the spread of this infection within a household prompts the question of whether antibiotic prophylaxis should be given among close contacts in future cases of necrotizing fasciitis.

Quantitative Mri And 3d-Printing For Monitoring Periprosthetic Joint Infection, Greg Hong 2022 The University of Western Ontario

Quantitative Mri And 3d-Printing For Monitoring Periprosthetic Joint Infection, Greg Hong

Electronic Thesis and Dissertation Repository

Joint replacements are becoming increasingly commonplace with over 130,000 joint arthroplasties being performed annually in Canada. Although joint replacement surgery is highly successful, implants do occasionally fail and need to be replaced via costly and difficult revision surgery. Periprosthetic joint infection (PJI) has recently become the leading reason for revision of both hip and knee replacements, which is unfortunate because PJI is difficult to diagnose and treat effectively; diagnosis is made particularly difficult by the lack of established non-invasive (imaging) means of evaluating PJI. This thesis aims to demonstrate that magnetic resonance imaging (MRI) has potential for diagnosing and ...

MEDI 8127 Scholarly Activities Pre-Clerkship

In the past decade, studies on vitamin D levels and relationships to orthopaedic patients have increased exponentially worldwide. Journals have established risk factors, proper assessment of vitamin D levels, supplementation standards, and dependent variables that effect prevalence.1

More specifically, many vitamin D studies in the field of orthopaedics and sports medicine have been conducted by analyzing NFL teams and NCAA Division I athletes and dividing the cohorts into player parameters such as age, BMI, race, team position, and supplement type. The results of these studies concluded that there is a large prevalence of vitamin D deficiency amongst athletes and ...


The Biomechanical Effects Of Glenoid And Humeral Lateralization On The Rotator Cuff Muscles In Reverse Total Shoulder Arthroplasty, Yousif Atwan 2022 The University of Western Ontario

The Biomechanical Effects Of Glenoid And Humeral Lateralization On The Rotator Cuff Muscles In Reverse Total Shoulder Arthroplasty, Yousif Atwan

Electronic Thesis and Dissertation Repository

The utilization of reverse total shoulder arthroplasty (RTSA) has continued to increase as its clinical indications expand. The optimization of the rotator cuff function in the setting of RTSA is poorly understood and poor outcomes are associated with lack of external and internal rotation function. The purpose of this study is to evaluate the role of implant parameters on rotator cuff tendon excursion and moment arms in the setting of RTSA.

Using a cadaveric based model, a custom designed modular RTSA system was implanted that allowed for incremental changes to glenoid and humeral lateralization. Using a shoulder simulator and optical ...

PanaSoMM

Finite element models can predict subject-specific chondrolabral stresses and help to elucidate the effect of under-coverage and incongruency of the hip joint in patients with dysplasia. However, complex stress patterns are difficult to generalize and evaluate statistically. With an established correspondence across shapes from statistical shape modeling (SSM), statistical parametric mapping (SPM) allows for evaluation of local variability while preserving model subject-specificity. Herein, we evaluated the combined application of SSM and SPM to compare cartilage contact stress between control subjects and patients with dysplasia.

Previously published hip joint contact stresses were mapped onto chondrolabral surface meshes and incorporated into an ...

Developmental dysplasia of the hip (DDH) is described as under-coverage of the femoral head by the acetabulum, resulting in mechanical instability. Though DDH is often diagnosed using plain film radiographs, these images cannot adequately capture 3D joint coverage. Herein, we applied a 3D statistical shape model (SSM) to the femur and hemi-pelvis of patients with DDH to objectively measure shape variation and evaluated whether SSM outputs could predict measurements of joint coverage.

The femur and hemi-pelvis were semi-automatically segmented from CT images (83 hips from 47 females with DDH). Surfaces of each hip were reconstructed from segmentations, aligned, and input ...
