Estimation Of Simulated Blood Loss By Orthopaedic Residents Before And After Brief Training, Jeffrey T. Jobe, Erika L. Garbrecht, Heather M. Menzer, Richard A. Miller

UNM Orthopaedic Research Journal

Background: Accurate estimation of blood loss (EBL) may be helpful for patient safety during certain operative procedures; however, medical students and residents are rarely instructed in EBL. In a series of two tests, we attempted to reveal any significant improvement in accuracy of EBL after a brief training session.

Methods: Fourteen orthopaedic residents were recruited. Participants estimated the amounts of simulated blood before and after a training session that involved a visual of 110 cm3 of the spilled fluid. Three volumes of 50, 237, and 531 cm3 of simulated blood were spilled on a lap sponge, blanket, and trash bag, …

Comparison Of Blood Loss Between Short-Stem And Conventional Femoral Implants In Total Hip Arthroplasty, Sean Kuehn, Drew K. Newhoff, Dukens Labaze, Aditi S. Majumdar, Rick J. Gehlert

UNM Orthopaedic Research Journal

Background: Although the postoperative results of total hip arthroplasty (THA) are generally successful, the standard technique and implant design have many proposed modifications. The purpose of the current study was to determine if using short-stem femoral implants minimized the intraoperative blood loss during THA when compared with conventional THA.

Methods: The medical records of patients who underwent THA using short-stem and conventional femoral implants between 2009 and 2013 were reviewed. Patients with previous surgical procedures for treating the acetabulum or proximal femur and patients without reported hematocrit levels were excluded; subsequently, a total of 53 patients for each group (short-stem …

Investigating Potential Role Of Surgeons In Sternal Wire Failure By Biomechanical Tests, Christina Salas, Rachel N. Tufaro, C Etta Tabe, Kwasi Addae-Mensah, W Daniel Tanberg, Christopher Buksa, Jessica A. Avila, Jorge A. Wernly

UNM Orthopaedic Research Journal

Background: Stainless steel wires are commonly used to close the sternum after cardiac-related operative procedures. However, complications have been reported associated with fracture of wires and subsequent migration into the chest cavity. The objective of this study was to biomechanically evaluate the role of surgeons in contributing to wire failure. We hypothesized that surgeons may impose damage to the sternal wire, which may be exacerbated by postoperative wire degradation and patient movement.

Methods: A biomimetic sternal model and custom test fixture simulated a median sternotomy. The sternum was closed by a fellowship-trained cardiothoracic surgeon using figure-of-eight and simple closure techniques. …

Design Of A Robotic Apparatus For Simulated Motion Of The Human Hand, Kenneth J. Smith, Sean R. Coss, Deana M. Mercer, Christina Salas, David I. Grow

UNM Orthopaedic Research Journal

Background: The hand is complex, in that any small disturbance to the flexor tendons, extensor tendons, and intrinsic muscles can result in dysfunction of the entire structure. We designed a robotic device to consistently load a native thumb carpometacarpal (CMC) joint in assessing the effects of ligamentous damage on stability of the thumb CMC joint.

Methods: The device consisted of a mechanical plate in which to fixate a cadaveric hand, a tendon-suture routing system, a bracket to couple multiple suture lines to a cable to maintain equal force among sutures and tendons, and the finger-thumb force measurement devices. To apply …

Postoperative Complications In Patients With Trapeziometacarpal Joint Osteoarthritis Treated With Carpometacarpal Arthroplasty: Report Of Two Cases, Jessica A. Avila, Taylor H. Parnall, Ericka L. Charley, Lauren N. Mercer, Elizabeth A. Mikola, Deana M. Mercer

UNM Orthopaedic Research Journal

Osteoarthritis of the carpometacarpal (CMC) joint, specifically, of the thumb trapeziometacarpal (TMC) joint, is a common condition in older women. Complications associated with surgical treatment range from transient tendinitis to wrist instability. We present two patients in whom complications developed after undergoing CMC arthroplasty. In one patient, rupture of the flexor carpi radialis (FCR) was noted postoperatively after using a combination of ligament reconstruction and tendon interposition with complete trapeziectomy. The second patient presented with a flexor pollicis longus (FPL) tendon that was tethered with sutures, in which surgical release of the entrapped FPL tendon led to successful treatment. In …

Postoperative Deep Vein Thrombosis And Pulmonary Embolism After Ankle Fusion In A Patient With Hemophilia A: A Case Report, Christopher P. Bankhead, Michael J. Hopson, Richard A. Miller

UNM Orthopaedic Research Journal

Deep vein thrombosis (DVT) and subsequent pulmonary embolism (PE) are uncommon postoperative complications of operative procedures for treating injuries of the foot and ankle. Because the disorder of hemophilia A prevents blood clotting and increases bleeding, patients with this condition have been even less likely to develop DVT and PE. We present a 36-year-old man with hemophilia A in whom operative ankle fusion for treating hemophilic arthropathy of the left ankle led to DVT and PE. After decreasing dosage of antihemophilic medication and administering enoxaparin, the symptoms improved and the patient was discharged from the hospital on postoperative day 5. …

Simultaneous Dislocation Of Both Interphalangeal Joints In The Same Digit Of A 56-Year-Old Woman With Workers’ Compensation: A Case Report, Danika Z. Boomer, Kristin M. Loker, Deana M. Mercer

UNM Orthopaedic Research Journal

Dislocation of the interphalangeal (IP) joints of the fingers, particularly on the ulnar side of the hand, is common; however, simultaneous dislocation of both IP joints of the same finger is uncommon, and no studies have reported this injury in patients with workers’ compensation claims. We describe a 56-year-old woman with simultaneous dislocation of distal and proximal IP joints, who was successfully treated using a dorsal blocking splint followed by several months of undergoing occupational therapy. She had sustained the injury from a fall on the ground at work and was promptly treated with open reduction at an outside facility. …

Metasynchronous Rupture Of Both Achilles Tendons In A Patient Undergoing Statin Therapy: A Case Report, Paul J. Johnson, Richard A. Miller

UNM Orthopaedic Research Journal

In treating cholesterol-related cardiovascular diseases, statins are commonly used as preventative medication and are associated with few side effects. However, recent studies have described a connection between statins and development of tendinopathy. Similar research has noted bilateral rupture of the Achilles tendon, a rare injury, in patients undergoing statin therapy. We describe a 74-yearold man undergoing statin (ie, simvastatin) therapy who presented with pain and swelling in the right ankle after exertional-type activity. Magnetic resonance imaging confirmed a rupture of the Achilles tendon, with rupture of the left Achilles tendon identified 5 weeks later without any obvious trauma-related event. Nonoperative …

Simultaneous Presence Of A Transligamentous Recurrent Motor Branch Of The Median Nerve And Palmaris Profundus Tendon In A Patient With Carpal Tunnel Syndrome: A Case Report, Dustin L. Larson, Moheb S. Moneim

UNM Orthopaedic Research Journal

Carpal tunnel syndrome (CTS) is the most frequently encountered entrapment of the peripheral nerves in the upper extremity. Abnormal anatomical variations involving the recurrent motor branch of the median nerve and presence of a palmaris profundus tendon have been reported. We present a 53-year-old man in whom open carpal tunnel release led to complete resolution of numbness, tingling, and pain in the right hand by 1 month postoperatively. Intraoperatively, the simultaneous presence of a transligamentous recurrent motor branch of the median nerve and palmaris profundus tendon in the carpal tunnel was found and excised. Surgeons should be aware of the …

Idiopathic Thrombocytopenic Purpura In A 21-Year-Old Collegiate Football Player: A Case Report, James A. Leinhart, Shane P. Cass, Matthew A. Tennison, Ronica A. Martinez, Christopher A. Mcgrew

UNM Orthopaedic Research Journal

Muscle cramps are commonly observed in collegiate athlete-patients; however, the condition may be a symptom of severe disorders. In particular, idiopathic thrombocytopenic purpura (ITP) may be a possible diagnosis and involves a decreased number of platelets in the bloodstream. We describe a 21-year-old collegiate player of American football with initially presented with cramping of the neck, abdomen, and forearms. Although findings of physical examination were normal, results of laboratory tests indicated ITP, and the patient was hospitalized for 3 days until the platelet count increased. Because the levels continued to decrease at 6-month followup, splenectomy and use of rituximab agents …

Notable Findings Of A Preparticipation Examination In An 18-Year-Old Volleyball Player: A Case Report, Stuart J. Lisle, Christopher A. Mcgrew

UNM Orthopaedic Research Journal

The preparticipation examination (PPE) is commonly performed to screen for potentially detrimental health conditions in competitive athletes to help decrease rates of morbidity and mortality associated with participation in sports. However, the significant clinical impact of PPE in the United States has yet to be determined. We describe an 18-year-old female athlete who presented with dizziness and a right-sided limp at 8 days after initial injury. Findings of PPE examination indicated that she had unknowingly sustained a concussion during a volleyball match and continued to play, which resulted in injury to the right foot. Despite abnormal findings of magnetic resonance …

Spare-Parts Technique For Concurrent Treatment Of Ectrodactyly Of The Feet And Syndactyly Of The Hands In A 2-Year-Old Boy: A Case Report, Brielle K. Payne, Mary E. Logue, Selina R. Silva, Deana M. Mercer

UNM Orthopaedic Research Journal

Syndactyly is the most frequently occurring congenital malformation of the limbs. Although common, few studies have reported treating syndactyly using Z-plasty with and without full-thickness grafting. We present a 2-year-old boy who presented to our clinic with ectrodactyly of the feet and simple complete syndactyly of two fingers on each hand. After ectrodactyly reconstruction, we used the excess foot skin to cover finger defects. The patient recovered well postoperatively, with matching skin and no trouble with hair growth. Use of a spare-parts technique can help avoid complications associated with harvesting grafts from other donor sites. The results reinforce the importance …

Federal Restrictions On Tribal Customary Law: The Importance Of Tribal Customary Law In Tribal Courts, Concetta R. Tsosie De Haro, Dine Nation

Tribal Law Journal

This article examines the adverse effects of federal case law and legislation on tribal courts and tribal courts’ ability to incorporate tribal customary law. Tribal customary law is the law given to tribes by holy deities which governs tribal ways of life. It is important to maintain tribal customary law because it strengthens tribal communities’ identities and cultural foundations. While Supreme Court precedent has, at different times, both restricted and promoted tribes’ ability to use tribal customary law to adjudicate the cases of tribal members, federal legislation including the Major Crimes Act, the Indian Civil Rights Act, the Tribal Law …

Black Water: The Devastating Effects Of Alcohol On The Core Values Of The A:Shiwi (Zuni), Christy Chapman

Tribal Law Journal

As in many Native American communities, alcohol use and abuse is an all too common problem among the Ashwi, members of Zuni Pueblo. Soon after the arrival of Anglo-American settlers, alcohol was introduced to the Zuni. Seeing its devastating effects, Zuni elders referred to this intoxicating substance as ‘black water.’ Since the introduction of black water, alcohol abuse among the Zuni has resulted in community members committing frequent criminal offenses, numerous health problems, and is the number-one cause of premature death among the Zuni.

Over the last century and a half, the devastating effects of black water have eroded the …

Postcolonial Management Of The Transboundary Guaraní Aquifer System: Indigenous Input As A Guide For Environmental Sustainability, Melissa Leonard

Tribal Law Journal

This article discusses the Guaraní Aquifer System, which is a vast groundwater source that spans across Argentina, Uruguay, Paraguay, and Brazil. The Guaraní Aquifer System is located beneath the ancestral homelands of the Guaraní indigenous peoples, yet it is exclusively managed by nation states. The Guaraní indigenous peoples have been deprived of their ancestral land and have no say in the utilization or management of the Aquifer. This article discusses social and legal theory relating to water management and governance, as well as Guaraní social organization, belief systems, and customary environmental law in the context of “postcolonial” water management. This …

Learning Commons Reference Collections In Arl Libraries, Cindy Pierard, Sever Bordeianu

University Libraries & Learning Sciences Faculty and Staff Publications

Many academic libraries have developed or partnered in the development of learning commons over the last two decades. Although the nature of these environments may vary, learning commons are characterized here as adaptable spaces in which services, programming, and specialized resources are brought together to support and enact specific learning and research activities.The development of learning commons spaces has resulted in significant changes in traditional library collections, including decisions to weed or relocate physical collections, to transition from print to electronic collections, and to develop collections to support new learning services, programs, and collaborations (Brown et al., 2014; Detmering …

Analyzing Social Construction Of Knowledge Online By Employing Interaction Analysis, Learning Analytics, And Social Network Analysis, Charlotte Nirmalani Gunawardena, Nick V. Flor, David Gomez, Damien Sanchez

University Libraries & Learning Sciences Faculty and Staff Publications

This article examines research methods for analyzing social construction of knowledge in online discussion forums. We begin with an examination of the Interaction Analysis Model (Gunawardena, Lowe, & Anderson, 1997) and its applicability to analyzing social construction of knowledge. Next, employing a dataset from an online discussion, we demonstrate how interaction analysis can be supplemented by employing other research techniques such as learning analytics and Social Network Analysis that shed light on the social dynamics that support knowledge construction. Learning analytics is the application of quantitative techniques for analyzing large volumes of distributed data ("big data") in order to discover …

Moxifloxacin: A Unique Cause Of Severe Hypoglycemia, Emily Ball, Sepehr Khashaei, Jeremy Raschke

Undergraduate Medical Student Research

As a class, quinolone antibiotics have been rarely associated with hypoglycemia in non-diabetic patients and rare reversible episodes of hypoglycemia documented in the literature typically occur within the duration of action of the medication. In this case, however, we believe the effect of the medication persisted much longer.

Fracking In Louisiana: The Missing Process/Land Use Distinction In State Preemption And Opportunities For Local Participation, Alex Ritchie

Faculty Scholarship

Oil and gas development is testing and defining the boundaries of local government authority and autonomy as concerned municipal entities and citizens seek to limit oil and gas operations. Advances in high-volume hydraulic fracturing have increased domestic oil and gas production to historic levels.) At the same time, national and international concerns about irreversible man-made global warming have focused on fossil fuel combustion. National groups opposed to continued reliance on oil and gas as an energy source have found willing partners in many local governments and their citizens, who are anxious about the local implications of drilling and fracking. Many …

Quality Improvement Conference: Effect Of Patient Safety Intelligence Inservice Training On Resident Psi Entry, Amanda Derylo, Josh Rider, Joanna Fair

Radiology Research and Scholarship

Hospital administrators rely heavily on incident reporting systems to capture adverse events. 13.5% of Medicare beneficiaries discharged in October 2008 experienced adverse events. 62% were not reported because staff did not perceive an event as reportable; 25% were not reported because staff commonly reported but did not report in this case. Nurses reported events most often. The Patient Safety Intelligence (formerly PSN) is an online adverse event reporting service provided by UNM Hospital. System-wide and departmental efforts to improve quality have included attempts to increase PSI reporting. A comprehensive ducational intervention program for anesthesiology resident physicians at the University of …
