The Effects Of Emerging Technology On Healthcare And The Difficulties Of Integration, Skyler J. Pavlish-Carpenter

Honors Undergraduate Theses

Background: Disruptive technology describes technology that is significantly more advanced than previous iterations, such as: 3D printing, genetic manipulation, stem cell research, innovative surgical procedures, and computer-based charting software. These technologies often require extensive overhauls to implement into older systems and must overcome many difficult financial and societal complications before they can be widely used. In a field like healthcare that makes frequent advancements, these difficulties can mean that the technology will not be utilized to its full potential or implemented at all.

Objective: To determine the inhibiting factors that prevent disruptive technology from being implemented in conventional healthcare.

Osteoid Osteoma: Contemporary Management, Shahryar Noordin, Salim Allana, Kiran Hilal, Riaz Hussain Lukhadwala, Anum Sadruddin Pidani, Nasir Ud Din

Section of Orthopaedic Surgery

Osteoid osteoma is a benign bone-forming tumor with hallmark of tumor cells directly forming mature bone. Osteoid osteoma accounts for around 5% of all bone tumors and 11% of benign bone tumors with a male predilection. It occurs predominantly in long bones of the appendicular skeleton. According to Musculoskeletal Tumor Society staging system for benign tumors, osteoid osteoma is a stage-2 lesion. It is classified based on location as cortical, cancellous, or subperiosteal. Nocturnal pain is the most common symptom that usually responds to salicyclates and non-steroidal anti-inflammatory medications. CT is the modality of choice not only for diagnosis but …

Superior Capsular Reconstruction In The Active Population With A Massive Irreparable Rotator Cuff Tear, Emmanuel Hernandez

Physician Assistant Scholarly Project Posters

The prevalence of rotator cuff tears is a leading cause of upper extremity functional disability and affects people across the lifespan. The primary age groups that are diagnosed include young adults as well as the elderly population. Approximately one-fifth of rotator cuff tears (RCT) are diagnosed as “massive” and prove to be difficult for orthopedic surgeons to repair. If the massive RCT is also diagnosed as “irreparable”, surgical intervention is technically difficult and can be extremely challenging. Historically, treatment options have been limited for the young population to invasive surgical intervention or conservative measures such as physical therapy and pharmacologic …

Below-Knee Amputations: A Review, Erika L. Garbrecht

UNM Orthopaedic Research Journal

At our institution, physicians from the orthopaedic department perform a considerable proportion of below-knee amputations. These amputations are performed to treat non-traumatic and traumatic injuries. However, the outcomes of amputation are not discussed as often in our educational experience as those of other procedures. The current review examines the current and relevant studies for indications and outcomes of patients with non-traumatic and traumatic conditions treated with below-knee amputations.

Midterm Results Of An Anatomical Radial Head Arthroplasty For Treating Fractures And Degenerative Joint Diseases Of The Radial Head, Gabriel Pertierra, Lauren L. Vernon, Francisco Rubio

UNM Orthopaedic Research Journal

Background: Radial head arthroplasty (RHA) is typically performed to restore elbow stability or function in patients with fractures or degenerative joint diseases. The procedure requires a specific operating technique to avoid complications such as overstuffing, capitellar erosion, stiffness, instability, micro motion, and loosening. It is difficult to restore native radial head function reliably.

Methods: We reviewed the medical records of 45 patients who underwent radial head arthroplasty using the ALIGN radial head implant (ALIGN Radial Head System, Skeletal Dynamics, Miami, FL) at our institution. A total of 15 patients met inclusion criteria and were contacted to complete a QuickDASH questionnaire, …

Chronic Tenosynovitis Caused By Mycobacterium Avium-Intracellulare Of The Flexor Tendons In A 65-Year-Old Man: A Case Report, Kourosh M. Kolahi, Moheb S. Moneim

UNM Orthopaedic Research Journal

We report a rare case of Mycobacterium aviumintracellulare flexor tenosynovitis in the hand of a 65-year-old man. The patient reported no history of penetrating trauma but was an avid gardener and presented nearly 2 years after the onset of symptoms. Our case highlights the difficulty in diagnosing mycobacterial infections owing to their lack of classic clinical and laboratory findings. Our patient underwent successful surgical debridement followed by oral antibiotic therapy, initiated 4 weeks after the culture was positive for a slow-growing organism.

Brachial Artery Vasculitis And Associated Stenosis Presenting As Elbow Pain In A 16-Year-Old Soccer Player: A Case Report, Eric R. Reynolds, Andrew D. Ashbaugh, James P. Toldi, Deana M. Mercer, Mark Langsfeld, Christopher A. Mcgrew

UNM Orthopaedic Research Journal

Chronic vascular occlusion in the upper extremity can result from repetitive trauma, atherosclerosis, proximal embolic events, hypercoagulable states, and systemic diseases such as collagen vascular disease and vasculitis. Considerable functional impairment can result from these maladies; however, sometimes the condition develops slowly with minimal effect on the patient. We describe a 16-year-old soccer player with slow-progressing elbow pain and loss of range in motion caused by brachial artery vasculitis and resultant brachial arterial stenosis. Although vascular insults and lesions rarely cause chronic vascular occlusion, physicians should consider this possibility in patients with localized pain or atrophy, especially if the condition …

Using Foot Pressure Analysis To Predict Reoccurrence Of Deformity For Children With Unilateral Clubfoot, Juanita Jean Wallace

Theses and Dissertations--Kinesiology and Health Promotion

Reoccurrence of deformity can affect upwards of 64% of children with clubfoot. The ability to use foot function as a measure of reoccurrence has not been previously assessed. The purpose of this investigation was to utilize foot pressure analysis to predict the probability of reoccurrence in children with unilateral clubfoot. Retrospective foot pressure data revealed predictive algorithms detecting the probability of experiencing any type of reoccurrence (overall reoccurrence) and for experiencing a tibialis anterior tendon transfer (TATT). The equation for overall reoccurrence reported sensitivity and specificity of 0.82 and 0.81 and the equation for TATT reported values of 0.81 and …

The Role Of Psychosocial Factors On Pre And Postoperative Pain In Patients With Femoral Acetabular Impingement, Kate N. Jochimsen

Theses and Dissertations--Rehabilitation Sciences

Femoral acetabular impingement (FAI) is a bony hip condition that often results in tears to the acetabular labrum. Patients with FAI experience pain, decreased function, and quality of life. FAI and its’ sequela are treated definitively with hip arthroscopy. Hip arthroscopy is being performed with increasing frequency, and while most patients respond favorably, a subset of 10-20% of patients have suboptimal outcomes.

Previous research suggests that mental status may be a primary driver in the way patients with FAI respond to and feel pain. Measures of mental status include the presence of mood disorders and psychosocial patient reported outcomes (PROs). …
