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 …

Motion-Tracking Drill System Using A Haptic Device For Evaluating And Training Motor Skills Of Orthopaedic Resident Physicians Outside The Operating Room: A Pilot Study, Ashkan Pourkand, Christina Salas, Deana M. Mercer, David I. Grow

UNM Orthopaedic Research Journal

Background: Although experience within the operating room can help surgeons learn simple bone-drilling techniques, outside training may be better suited for complex procedures. We adapted a rotary handpiece with dual trigger and drilling attachments to a haptic device to train and evaluate motor skills of orthopaedic resident physicians outside of the operating room.

Methods: A total of 7 participants with varying levels of skill in orthopaedic surgery were asked to perform a task three times: drill a hole (at 45° from the normal angle) through both cortices of a synthetic diaphysis of a distal radius. Acceleration and acoustic data were …

Lipoma Of The Index Finger In A 64-Year-Old Man: A Case Report, Norfleet B. Thompson, Moheb S. Moneim

UNM Orthopaedic Research Journal

Lipomas are benign tumors composed of adipose tissue and typically encountered in middle-aged patients. Although the etiology remains unknown, this lesion can occur throughout the body. However, it is rarely seen in the finger. Typical treatment has often involved observation, but excision techniques have also reported successful outcomes. We describe a 64-year-old male patient who reported to our clinic with a painless soft-tissue mass in the index finger of his left hand, and we performed operative excision for treatment. The findings of physical examinations, radiographs, and magnetic resonance imaging tests had indicated the presence of lipoma, and results of pathological …

Reliability Of Posterolateral Acromion Process To Examination Table Measurement To Estimate Shoulder Protraction Contracture, Bart D. Taylor, Antonia M. Norris, Zachary J. Mertz, Todd E. Davenport

School of Pharmacy Faculty Articles

Study Design: Retrospective study. Objectives: To determine the reliability of measuring the perpendicular distance between the posterolateral acromion process and examination table to estimate passive shoulder protraction in student physical therapists.

Background: Previous research has identified scapular dyskinesis to be associated with musculoskeletal shoulder pain, and commonly addressed by physical therapists. Tightness of the anterior shoulder muscles may be associated with scapular movement abnormality. Thus, reliable clinical measurements for anterior shoulder muscle length are imporrant for physical therapy care.

Methods: After a 1 0-minute review session, two measurements of the distance between the posterior acromion process and examination table were …

Bioactive Lipid Coating Of Bone Allografts Direct Engraftment And Fate Determination Of Bone Marrow-Derived Cells In Rat Gfp Chimeras, Anusuya Das, Claire E. Segar, Yihsuan Chu, Tiffany W. Wang, Yon Lin, Chunxi Yang, Roy C. Ogle

School of Medical Diagnostics & Translational Sciences Publications

Bone grafting procedures are performed to treat wounds incurred during wartime trauma, accidents, and tumor resections. Endogenous mechanisms of repair are often insufficient to ensure integration between host and donor bone and subsequent restoration of function. We investigated the role that bone marrow-derived cells play in bone regeneration and sought to increase their contributions by functionalizing bone allografts with bioactive lipid coatings. Polymer-coated allografts were used to locally deliver the immunomodulatory small molecule FTY720 in tibial defects created in rat bone marrow chimeras containing genetically-labeled bone marrow for monitoring cell origin and fate. Donor bone marrow contributed significantly to both …

Severely Deformed Extraarticular Fractures Of The Scapula: A Review, Sean B. Kuehn

UNM Orthopaedic Research Journal

Nonoperative treatment of severely deformed fractures of the scapula was historically common. However, the findings of newer research have challenged the notion that conservatively managing these fractures results in the most successful outcomes. In an attempt to possibly reveal important indicators for surgical treatment, I reviewed studies on scapula fractures involving scapular anatomy; associated injuries; technological advances that have helped with fracture evaluation; and treatment outcomes between nonsurgical and surgical methods. Although a universally accepted classification scheme of scapula fractures does not exist, use of 3D reconstruction with computed tomography can help define the level and category of fracture deformity. …

Treatment Of Full Circumferential Segmental Bone Loss Of The Tibia Resulting From Acute Traumatic Injuries And Complications: A Review, Gregory C. Strohmeyer

UNM Orthopaedic Research Journal

Full circumferential segmental bone loss of the tibia presents a challenge to orthopaedic surgeons. These open fractures often involve extensive soft-tissue damage, which can contribute to poor long-term outcomes even if the tibia is successfully reconstructed. Although amputation was historically used to treat full circumferential segmental bone loss of the tibia because of the severity of the injury, the development of new reconstruction procedures has provided the option of limb salvage techniques. I reviewed studies on treatment of traumatic tibia bone loss, focusing particularly on full circumferential bone loss of greater than 3 cm. Treatment options included amputation, allograft replacement, …

Isolated Traumatic Subscapularis Tear In A 12-Year-Old Male Gymnast: A Case Report, Katherine J. Gavin, Gehron P. Treme

UNM Orthopaedic Research Journal

Isolated avulsion fractures of the lesser tuberosity are rarely encountered in younger and older populations. However, because the tendon of the subscapularis insertion is stronger in skeletally immature individuals, isolated tears to the tendon occur more commonly in adults than children and adolescents. Most studies have been limited to case reports that mainly describe traumatic subscapularis tears in adolescent athlete-patients. We present a 12-year-old male gymnast who reported to our clinic with pain and weakness in the right shoulder at 2 months after the initial injury. We performed open repair with suture anchor fixation for treatment of an isolated subscapularis …

Severe Ischemia Of The Finger After Use Of Compressive Self-Adherent Wrap: Report Of Two Cases, Andrea B. Lese, Elizabeth A. Mikola, Deana M. Mercer

UNM Orthopaedic Research Journal

Use of Coban compressive self-adherent wraps (3M, St Paul, MN) has been found helpful in treating various conditions and injuries of the extremities, including lymphedema, edema in burned hands, and sprains or strains. However, the availability and easy application of the wrap have resulted in its common usage with or without adequate instructions. We report two cases in which severe pain and ischemia developed after this bandage was circumferentially applied to a finger to stop bleeding from a simple laceration. One patient required amputation at the level of the proximal interphalangeal joint; the other had resolution of venous congestion symptoms …

Nonunion After Hybrid Plating With Locking And Nonlocking Screws In Radius And Ulna Shaft Fractures: Report Of Two Cases, Zainab Cheema, Nathan E. Huff, Deana M. Mercer

UNM Orthopaedic Research Journal

Conventional compression plating has been found effective in treating forearm diaphyseal fractures, providing stability as well as resistance to axial, torsional, and bending forces. Locked plating has provided stability without frictional force between the bone-plate interface, which may help preserve periosteal blood supply, and is useful in treating metaphyseal, comminuted, and osteoporotic fractures. Hybrid plating has been used in an attempt to combine the strengths of these two techniques; however, in the context of simple forearm diaphyseal fractures with healthy bone, its effectiveness is only theoretical. We describe two patients in whom open reduction and internal fixation with hybrid plating …

Third Extensor Compartment Disruption And The Biomechanics Of Thumb Extension, Christina Salas, Drew K. Newhoff, Zainab Cheema, Allison A. Richards, Deana M. Mercer, Amanda K. Medoro, Ahmed M. Afifi, Moheb S. Moneim, John M. Veitch

UNM Orthopaedic Research Journal

Background: Procedures involving release of the third dorsal wrist compartment have been thought to transpose the extensor pollicis longus (EPL) tendon from its anatomical position. Few studies, however, have reported on the effects this might have on function and mechanics of the thumb. We analyzed the impacts of intact extensor retinaculum, release of the third dorsal compartment, and removal of Lister’s tubercle on thumb extension.

Methods: A total of 15 fresh-frozen cadaveric upper extremities (eight male, seven female; mean age, 52 years; range, 38-59 years) were used. For each specimen, three phases of testing were analyzed: the extensor retinaculum was …

Removal Of Partly Threaded Cannulated Screws After Treatment Of Slipped Capital Femoral Epiphysis: A Pilot Study, Nathan T. Morrell, Ian A. Power, Dukens Labaze, Elizabeth A. Szalay

UNM Orthopaedic Research Journal

Background: Partly threaded cannulated screws (PTCS) are currently recommended for management of slipped capital femoral epiphysis (SCFE), but no advantage of these screws over fully threaded cannulated screws (FTCS) has been demonstrated. We investigated whether PTCS are more difficult to remove than FTCS.

Methods: The records of 33 patients who underwent implant removal after operative treatment of SCFE were reviewed, and the following data were collected: age and sex of the patient, type of screw used (partly or fully threaded), length of removal operation, and any comments on the difficulty of screw removal.

Results: Sixty-one percent of operative reports for …

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 …

Open Reduction And Internal Fixation For Treatment Of Proximal Humerus Fractures: A Review, Heather K. Woodin

UNM Orthopaedic Research Journal

Fractures of the proximal humerus are common in older patients, and the incidence of these fractures in the United States is expected to notably increase with the aging population. Nonoperative procedures have been preferred in elderly patients with stable fracture patterns to avoid complications associated with osteoporotic bone. However, more complex and unstable fracture patterns often necessitate operative techniques to allow for more anatomical healing. Although proximal humerus fractures have been thoroughly examined, systemized, and studied, no clear method to choosing an appropriate surgical treatment or candidate has been accepted. I reviewed the role of the following factors on successful …

Carpal Tunnel Syndrome Associated With A Palmaris Profundus Tendon: A Case Report, Andrea B. Lese, Kristin M. Loker, Moheb S. Moneim

UNM Orthopaedic Research Journal

Carpal tunnel syndrome (CTS) is often found in adults and may be associated with rare anatomical abnormalities in the hand, such as the presence of a palmaris profundus tendon. Although the muscle was originally thought to be a variant of the palmaris longus muscle, some case studies have described both structures during operative treatment with open carpal tunnel release. We present a case of a 51-year-old woman who underwent open carpal tunnel release to treat CTS of the right hand. Preoperatively, results of electrodiagnostic tests and clinical examinations, respectively, were normal and equivocal. Intraoperatively, a palmaris profundus tendon was found …

Surgical Treatment Of Chronic Dislocation Of A Posterior Tibial Tendon In A Collegiate Athlete: A Case Report, Tony G. Pedri, Richard A. Miller

UNM Orthopaedic Research Journal

Traumatic dislocation of the posterior tibial tendon (PTT) is a rare and often misdiagnosed injury. The limited number of cases, ambiguous results of initial imaging studies, and presence of symptoms similar to medial ankle sprains can contribute to unsuccessful long-term treatment. Current studies, although limited, report high rates of failure in nonoperative compared with operative treatment. We describe a 21-year-old male baseball player who experienced pain and mild swelling in his ankle after falling while running at full speed. After 5 months of continuous pain in the medial ankle, the patient was referred to our clinic and underwent suture anchor …

Custom-Made Angled Polyethylene Insert Exchange For Treatment Of Valgus Malalignment In Revision Total Knee Arthroplasty: A Case Report, Reilly J. Kuehn, Ch Christopher R Hanosh

UNM Orthopaedic Research Journal

Single- and dual-component revisions have typically been used to correct coronal malalignment after total knee arthroplasty (TKA). However, realignment of well-fixed components can result in complications such as bone loss and the need for increasing constraint of implants. Exchange to a custom-made angled polyethylene insert, although primarily implemented in cases of osteolysis, has been described with low complication rates and minimal loss of motion. We describe a 74-year-old woman who underwent TKA in January 2006 and presented to our clinic in March 2013 with symptoms of pain and instability of the right knee. We performed a revision TKA using two …

Scaphoid Stress Fracture In A 65-Year-Old Man With Low Bone Mineral Density: A Case Report, Dean W. Smith

UNM Orthopaedic Research Journal

Although commonly reported in women and less commonly in younger athletes, no studies have reported stress fractures of the scaphoid in older, sedentary men. Because of its rarity, osteoporosis in older men is often unrecognized and only diagnosed after the fracture. I describe a previously sedentary 65-year-old man who presented to my clinic with pain in the right wrist after his first day of intense physical activity and underwent 8 weeks of splinting and bracing for treatment of a fracture of the waist of the scaphoid. Ten weeks after the pain began, a computed tomography image revealed healing of the …
