Platelet-Rich Plasma And Other Cellular Strategies In Orthopedic Surgery, P. N. Williams, G. Moran, J. P. Bradley, N. S. Elattrache, J. S. Dines

Journal Articles

The use of biologics in the treatment of musculoskeletal disease has become increasingly more common as research studies continue to provide further elucidation of their mechanisms in healing. Platelet-rich plasma, patches, growth factors, and stem cells are among the many biologics under active investigation and have varying levels of success in augmenting surgical or nonoperative interventions. However, the limitations of these treatments exist, and clear guidelines for their indications and application have yet to be established. Well-designed clinical trials will help determine the appropriate future use of biologics to ensure consistent outcomes.

Pregabalin And Pain After Total Knee Arthroplasty: A Double-Blind, Randomized, Placebo-Controlled, Multidose Trial, J. T. Yadeau, Y. Lin, D. J. Mayman, E. A. Goytizolo, M. M. Alexiades, D. E. Padgett, K. G. Fields, A. K. Goon, J. Curren, G. H. Westrich, +4 Additional Authors

Journal Articles

BACKGROUND: Pregabalin may reduce postoperative pain and opioid use. Higher doses may be more effective, but may cause sedation and confusion. This prospective, randomized, blinded, placebo-controlled study tested the hypothesis that pregabalin reduces pain at 2 weeks after total knee arthroplasty, but increases drowsiness and confusion. METHODS: Patients (30 per group) received capsules containing pregabalin (0, 50, 100, or 150 mg); two capsules before surgery, one capsule twice a day until postoperative day (POD) 14, one on POD15, and one on POD16. Multimodal analgesia included femoral nerve block, epidural analgesia, oxycodone-paracetamol, and meloxicam. The primary outcome was pain with flexion …

Effect Of Bone Loss In Anterior Shoulder Instability, G. H. Garcia, J. N. Liu, D. M. Dines, J. S. Dines

Journal Articles

Anterior shoulder instability with bone loss can be a difficult problem to treat. It usually involves a component of either glenoid deficiency or a Hill-Sachs lesion. Recent data shows that soft tissue procedures alone are typically not adequate to provide stability to the shoulder. As such, numerous surgical procedures have been described to directly address these bony deficits. For glenoid defects, coracoid transfer and iliac crest bone block procedures are popular and effective. For humeral head defects, both remplissage and osteochondral allografts have decreased the rates of recurrent instability. Our review provides an overview of current literature addressing these treatment …

Comorbid Profile Rather Than Age Determines Hip Fracture Mortality In A Nonagenarian Population, A. Graver, S. Merwin, L. Collins, N. Kohn, A. Goldman

Journal Articles

BACKGROUND: In light of poor outcomes with nonoperative management of hip fractures, orthopedic surgeons are faced with difficult decisions about which patients are too ill or too old for surgical treatment. QUESTIONS/PURPOSES: This study sought to investigate if patients over 90 years had different preoperative laboratory, clinical, and injury characteristics than younger patients with the same injury. We compared our cohort with previously published data. We wished to identify if there were pre-injury risk factors associated with 30-day mortality, which could be modified to enhance postoperative outcomes. METHODS: This is a retrospective review of 198 operatively managed hip fractures in …

Shoulder Arthroplasty: Return To Sport, M. M. Khair, J. S. Dines, D. M. Dines

Journal Articles

CONTEXT: Increasingly, total shoulder arthroplasty is being performed not only to treat the pain associated with glenohumeral arthritis but also to return patients to the level of activity and function they enjoyed prior to the development of arthritis. While return to sport and activity have been studied in the total knee and total hip replacement literature, it is only relatively recently that the same focus has been placed on total shoulder replacements. EVIDENCE ACQUISITION: PubMed database from the years 2000 to 2014. All studies relevant to shoulder arthroplasty and return to sport were included in the review. STUDY DESIGN: Clinical …

Coping With Congenital Hand Differences, L. E. Franzblau, K. C. Chung, N. Carlozzi, A. Y. T. Chin, K. W. Nellans, J. F. Waljee

Journal Articles

Background: Although functional outcomes following reconstruction for congenital hand differences are frequently described, much less is known regarding children's ability to cope with the psychosocial effects of these conditions. The authors qualitatively explored stress and coping mechanisms among children following reconstructive surgery for congenital hand differences. Methods: Forty patients and their parents participated in semistructured interviews examining children's stress related to hand functioning and appearance, emotional responses to stress, and coping strategies. Interviews were audiotaped, transcribed, and analyzed thematically. A consensus taxonomy for classifying content evolved from comparisons of coding by two reviewers. Themes expressed by participants were studied for …

A New Method For Calculating Femoral Anterior Cortex Point Location And Its Effect On Component Sizing And Placement, M. R. Mahfouz, E. E. A. Fatah, L. Bowers, G. Scuderi

Journal Articles

Variation in anterior femoral cortex morphology can cause improper component placement and alignment. When surgical inaccuracies occur, the mechanical properties of the distal femur may be altered, which could result in lower surgical success rates and an increased chance of postoperative complications. The purpose of the study is to come up with a reproducible computational algorithm to simulate what the surgeon does in the operating room. This method could help in surgical preplanning, patient-specific instruments, and implant design. From there, we evaluated (1) the angular difference between reference alignment axes; and (2) whether the location of the anterior cortex point …

Minimally Invasive Knee Arthroplasty: An Overview, A. J. Tria, G. R. Scuderi

Journal Articles

Minimally invasive surgery (MIS) for arthroplasty of the knee began with surgery for unicondylar knee arthroplasty (UKA). Partial knee replacements were designed in the 1970s and were amenable to a more limited exposure. In the 1990s Repicci popularized the MIS for UKA. Surgeons began to apply his concepts to total knee arthroplasty. Four MIS surgical techniques were developed: quadriceps sparing, mini-mid vastus, mini-subvastus, and mini-medial parapatellar. The quadriceps sparing technique is the most limited one and is also the most difficult. However, it is the least invasive and allows rapid recovery. The mini-midvastus is the most common technique because it …

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 …

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.

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 …

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 …

Survey Of Current Articles Published On Total Ankle Arthroplasty And Ankle Fusion, Tony G. Pedri, Richard A. Miller

UNM Orthopaedic Research Journal

In the United States, ankle fusion is more commonly performed than total ankle arthroplasty (TAA) for treatment of degenerative joint disease of the ankle. However, recent advances in implant design and technique have led to a renewed interest in research on TAA. To shed light on current research trends and limited data rather than examine the merits between both methods, we performed a PubMed search of studies on TAA and ankle fusion between January 1, 2009, and January 1, 2015, published in both the American edition of the Journal of Bone and Joint Surgery (JBJS) and Foot & Ankle International …

The Pediatric Orthopaedic Trauma Season: Does It Exist?, Ava A. Boswell, Seth B. Mccord, Cole L. Paffett, Anthony Kallur

UNM Orthopaedic Research Journal

Background: It remains unclear whether pediatric trauma, including fracture, occurs more frequently at a certain time of the year. We developed a database based on the University of New Mexico orthopaedics consult log (OCL) with the aim of determining whether pediatric fractures have a seasonal predilection.

Methods: The OCL for 2009 and 2010, representing a total of 2385 patient visits, was reviewed, and data on patients who were 17 years of age or younger who were treated for trauma were collected. The months and seasons of the year in which the trauma occurred were recorded.

Results: The OCL for 2009 …
