Biologics In Achilles Tendon Healing And Repair: A Review, E. Shapiro, D. Grande, M. Drakos

Journal Articles

Injuries of the Achilles tendon are relatively common with potentially devastating outcomes. Healing Achilles tendons form a fibrovascular scar resulting in a tendon which may be mechanically weaker than the native tendon. The resulting strength deficit causes a high risk for reinjury and other complications. Treatments using biologics aim to restore the normal properties of the native tendon and reduce the risk of rerupture and maximize tendon function. The purpose of this review was to summarize the current findings of various therapies using biologics in an attempt to improve the prognosis of Achilles tendon ruptures and tendinopathies. A PubMed search …

Research Round-Up: Manual Muscle Testing, Mary Insana Fisher, Shana Harrington

Physical Therapy Faculty Publications

Manual muscle testing was developed in response to the need to assess muscle strength losses during the polio outbreak in early part of the 20th century. The development of this original method is credited to Wilhelmine Wright and Robert W. Lovett, MD. Wright presented this method in 1912 in the Boston Medical Surgical Journal, and Lovett expanded the description of the testing method in 1916 in the Journal of the American Medical Association. The development of quantifying muscle strength by rating force generated against external resistance was an important development in objectifying assessment methods of the time.

Today, manual muscle …

Workup And Treatment Of Acute Peripheral Nerve Injuries: A Review, Scott D. Evans

UNM Orthopaedic Research Journal

Peripheral nerve injury (PNI) can be a devastating and life-changing condition, normally caused from traumatic and iatrogenic events. Proper treatment of PNI remains difficult, with less than half of surgical procedures resulting in good or excellent outcomes. Subsequently, physicians should be aware of important principles that can help with management of acute PNI. I reviewed studies on PNI involving anatomy and classification schemes; workup such as electrodiagnostic tests, imaging procedures, and surgical indications; and operative treatment options (including nerve repair and use of nerve grafts and conduits, and nerve, muscle, and tendon transfers). Although treatment of these injuries continues to …

Complications And Predictors Of Need For Return To The Operating Room In The Treatment Of Supracondylar Humerus Fractures In Children, Matthew E. Oetgen, Gudrun E. Mirick, Lara Atwater, John F. Lovejoy

Orthopaedic Surgery Faculty Publications

Supracondylar humerus fractures are common pediatric injuries. Little is known about the risk factors for repeat operative procedures. A retrospective chart review of 709 patients treated for a displaced supracondylar humerus fracture was performed to identify risk factors for return to the operating room during the initial post-operative period. Deviations of routine fracture care were recorded and complication rates were compared between Gartland type 2 and 3 fractures using logistic regression. Type 3 fractures were found to have a higher complication rate, and, specifically, more peri-operative nerve palsies, more likely to need to return to the operating room for hardware …

Occupational Therapy Doctorate Capstone Projects

The Capstone Project is focused on communicating, influencing and educating other health care professionals regarding the role of occupational therapy in the future model of primary care delivery initiated by the adoption of the Affordable Care Act and the Triple Aim Initiative. Currently, primary care, the largest health care platform in United States, is not inclusive of occupational therapy services. Occupational therapists have the scope, knowledge and understanding to be part of the redesigned team model of primary care. Educating those currently working in primary care about adding occupational therapy services can have a significant impact on the profession of …

Expandable Total Humeral Replacement In A Child With Osteosarcoma, Eric R. Henderson, Jidi Gao, John Groundland, Odion Binitie, G. Douglas Letson

Orthopaedics and Sports Medicine Faculty Publications

Case. A right-handed 8-year-old female patient presented with a conventional, high-grade osteosarcoma involving her right humerus; through-shoulder amputation was recommended. After consultation, total humerus resection with expandable, total humeral endoprosthesis reconstruction was performed with a sleeve to encourage soft-tissue ingrowth. At three-year follow-up she has received one lengthening procedure and her functional scores are excellent. Conclusion. Total humeral resection and replacement in the pediatric population are rare and although early reports of expandable total humeral endoprosthesis outcomes demonstrate high failure rates, this patient’s success indicates that expandable total humeral replacement is a viable option.

The aim of this study was to assess the effect of sex and low back pain status with the use of two measures of trunk postural control, the first based on chair motion, and the second based on trunk motion.

Methods

Thirty-six subjects (with and without low back pain) performed three 60-s trunk postural control trials with their eyes closed while seated on an …

Cell Stimulation And Calcium Mobilization By Picosecond Electric Pulses, Iurii Semenov, Shu Xiao, Dongkoo Kang, Karl H. Schoenbach, Andrei G. Pakhomov

Bioelectrics Publications

We tested if picosecond electric pulses (psEP; 190 kV/cm, 500 ps at 50% height), which are much shorter than channel activation time, can activate voltage-gated (VG) channels. Cytosolic Ca²⁺ was monitored by Fura-2 ratiometric imaging in GH3 and NG108 cells (which express multiple types of VG calcium channels, VGCC), and in CHO cells (which express no VGCC). Trains of up to 100 psEP at 1 kHz elicited no response in CHO cells. However, even a single psEP significantly increased Ca²⁺ in both GH3 (by 114 +/- 48 nM) and NG108 cells (by 6 +/- 1.1 nM). Trains of …

Adolescent Idiopathic Scoliosis: Comparing And Contrasting Operative Versus Non-Operative Treatment Abstract, Ethan Morris

Physician Assistant Scholarly Project Posters

• Adolescent idiopathic scoliosis (AIS) is the most common form of scoliosis. It affects 2-4 percent of adolescents aged 10-16 years. Although most adolescents diagnosed with scoliosis will not develop clinical symptoms, ten percent will progress and require medical intervention due to the potential for rib deformity and respiratory compromise as well as significant emotional distress due to aesthetic changes in appearance. Primary care providers should be prepared to evaluate and recommend treatment when idiopathic scoliosis is discovered or addressed by the patient. Three major factors that determine whether scoliosis will progress are patient gender, magnitude of curve on presentation, …

Oncology Section Edge Task Force On Breast Cancer Outcomes: A Systematic Review Of Outcome Measures For Functional Mobility, Mary Insana Fisher, Jeannette Lee, Claire Davies, Hannah Geyer, Genevieve Colon, Lucinda Pfalzer

Physical Therapy Faculty Publications

Background: Breast cancer treatments in women with breast cancer often result in physical impairments that lead to activity limitations and participation restrictions. These limitations and restrictions manifest in impaired functional mobility skills that may impact survivorship. Thus, evaluation of functional mobility is an important part of survivorship care.

Purpose: To identify functional mobility outcome measures that possess strong psychometric properties and are clinically useful for examination of women treated for breast cancer.

Methods: Multiple electronic databases were searched for articles published after 1995. Studies were included if they reported psychometric properties, used clinically feasible methods, were performed on adults, and …

Nonthermal Atmospheric Pressure Plasma Enhances Mouse Limb Bud Survival, Growth, And Elongation., Natalie Chernets, Jun Zhang, Marla J Steinbeck, Deepa S Kurpad, Eiki Koyama, Gary Friedman, Theresa A. Freeman

Department of Orthopaedic Surgery Faculty Papers

The enhanced differentiation of mesenchymal cells into chondrocytes or osteoblasts is of paramount importance in tissue engineering and regenerative therapies. A newly emerging body of evidence demonstrates that appendage regeneration is dependent on reactive oxygen species (ROS) production and signaling. Thus, we hypothesized that mesenchymal cell stimulation by nonthermal (NT)-plasma, which produces and induces ROS, would (1) promote skeletal cell differentiation and (2) limb autopod development. Stimulation with a single treatment of NT-plasma enhanced survival, growth, and elongation of mouse limb autopods in an in vitro organ culture system. Noticeable changes included enhanced development of digit length and definition of …
