3d Bioprinter + Electrospinner For Bone-Ligament Tissue Engineering, Sherif H. Aboubakr, Steven Nery, Lauren Long, Christopher A. Buksa, Chanju Fritch, Christina Salas

UNM Orthopaedic Research Journal

Modern 3D bioprinters have been shown to allow for precise control of structural geometry to build patientspecific scaffolds for tissue regeneration—primarily nonload- bearing tissue. However, 3D bioprinting is limited by cell viability, polymer cross-linking characteristics, and poor tensile properties. In comparison, electrospinning has been used to form fibrous structures with accelerated cellular maturation properties, improved growth and migration of cells, and increased tensile properties. Conversely, the mostly uncontrolled deposition of electrospun fibers can limit pore size and cell infiltration. In our Orthopaedic Biomechanics & Biomaterials Laboratory, a custom 3D Bioprinter + Electrospinner hybrid system (E-Spin Printer) was designed to merge …

Pilot Study Investigating The Use Of 3d Printing In Designing Upper-Extremity Prosthetics For Children: A Progress Report, Lauren Long, Christina Salas, Deana M. Mercer, Selina R. Silva, Jared Knigge

UNM Orthopaedic Research Journal

The availability and cost-effectiveness of functional prototypes and designs has increased considerably over the last decade because of 3D printing. The growing field of biomedical engineering is expanding on 3D-printing technology to make low-cost, upper-extremity prosthetics. This pilot study reports on the potential use of 3D printing for low-cost, upper-extremity prosthetics, specifically prosthetic hands for children. We start by characterizing existing open-source, 3D-printed upper-extremity prosthetics to determine their mechanical strength, statically and dynamically. Based on outcomes from these early tests, we optimize the existing designs to develop a new prosthetic. The prosthetic design, fabricated in The University of New Mexico …

Missed Early Glenohumeral Septic Arthritis During Emergency Department Visit Owing To Low Virulence Streptococcus Mitis: A Case Report, Ashley A. Crum, Christopher A. Mcgrew, Matthew A. Tennison

UNM Orthopaedic Research Journal

Glenohumeral joint septic arthritis in a native joint is uncommon but can be debilitating if not treated early. Septic arthritis does not always present with the typical clinical findings, especially in immunocompromised patients. We report a rare case of glenohumeral septic arthritis from Streptococcus mitis infection in a diabetic woman that was initially missed on first presentation in the emergency department (ED). The exact cause of infection in this case remains unclear but is likely due to poor dentition and possible transient bacteremia in the setting of large rotator cuff tear in an immunocompromised patient (diabetes). The patient had a …

Posttraumatic Attenuation Of The Lisfranc Ligament In A 14-Year-Old Athlete: A Case Report, Paul J. Johnson, David M. Bennett

UNM Orthopaedic Research Journal

Lisfranc injuries in children are rare and range from mild midfoot sprains to severe traumatic fracture-dislocations. Management of sprains is nonoperative, whereas treatment of fracture-dislocations often requires internal fixation. We present a unique case of a midfoot sprain in a 14-year-old adolescent boy, with gradual increased instability at the joint owing to attenuation of the Lisfranc ligament. Closed reduction and percutaneous pinning resulted in successful treatment at 3 weeks postoperatively. Midfoot sprains may lead to further ligamentous attenuation and widening as seen on radiographs and thus should be monitored for signs of persistent pain and instability. Because midfoot instability contributes …

Capitate Stress Injuries Of Both Wrists In An Adolescent Female Gymnast: A Case Report, Brynne R.W Latterell, Deana M. Mercer, Shane P. Cass, Christopher A. Mcgrew

UNM Orthopaedic Research Journal

Gymnastic activities expose the wrist to a wide variety of overuse and acute stresses. Injuries to the distal radius are the most commonly reported gymnastic wrist condition; however, many other structures are at risk of injury from the sport’s high acute and overuse demands, including the carpal bones, most commonly the scaphoid. We describe a 17-year-old female, high-level gymnast in whom stress injuries to both capitate bones were ultimately diagnosed after initial symptoms of pain. This case demonstrated the need for prompt recognition, without which much chronic and debilitating injury would develop. For successful diagnosis, healthcare providers should carefully examine …

Carpal Tunnel Release During Pregnancy: Report Of Two Cases, Erica J. Gauger, Deana M. Mercer, Moheb S. Moneim

UNM Orthopaedic Research Journal

Symptoms of carpal tunnel syndrome are common occurrences during pregnancy, particularly in the third trimester. Most patients undergo successful nonoperative treatment shortly after birth or the cessation of breast feeding. However, symptoms noted earlier during pregnancy are more likely to be severe and persistent. We present the cases of two women who developed symptoms of severe carpal tunnel syndrome during the second trimester and did not improve with nonoperative measures. Both underwent carpal tunnel release during pregnancy, with excellent postoperative result. Obstetric providers and surgeons alike should consider surgical treatment for patients with carpal tunnel syndrome who do not improve …

Lipoma Of The Tendon Sheath Causing Symptoms Of De Quervain’S Tenosynovitis: A Case Report, James Rose, Moheb S. Moneim

UNM Orthopaedic Research Journal

Deep lipomas arising from the extensor compartments of the wrist are extremely rare. Owing to infrequent presentation and mass effect on nearby structures, lipomas can be mistaken for other clinical entities. We describe a 70-year-old woman who presented to our clinic with symptoms initially suggestive of de Quervain’s tenosynovitis of the left wrist. However, findings of physical examinations and imaging techniques revealed a lipoma of the tendon sheath of the second dorsal compartment. The patient was successfully treated operatively, with excision and release of the first dorsal compartment. To help accurately diagnosis and treat lipomas of the wrist in deep-tissue …

Diagnosing An Acute Quadratus Plantae Tear In A 37-Year-Old Athlete: A Case Report, James P. Toldi, Shane P. Cass, Richard A. Miller, Christopher A. Mcgrew

UNM Orthopaedic Research Journal

Foot injuries occur frequently in distance runners and can notably impact training performance. Common diagnoses include plantar fasciitis, tendinopathies of the forefoot or midfoot, and stress fractures of the metatarsals. Occasionally, more obscure structures may be involved. We describe a 37-year-old male distance runner who presented with symptoms of heel pain and ecchymosis, suggesting an acute plantar fascia injury. However, findings of magnetic resonance imaging revealed a tear to the quadratus plantae (QP). The patient gradually returned to normal levels of physical activity, with complete resolution of symptoms by 4 months after the initial injury. Healthcare providers should be aware …

Unsuccessful Metatarsophalangeal Joint Replacement For Treating Arthritis Of The Great Toe: Report Of Three Cases, Jory Wasserburger, Paul J. Johnson, Katherine J. Gavin, Richard A. Miller

UNM Orthopaedic Research Journal

Metatarsophalangeal (MTP) joint fusion or replacement are commonly performed for treating advanced arthritis of the MTP joint of the great toe. However, results of MTP joint arthroplasty have shown no clear advantages compared to those of fusion. We present a 72-year old woman (case 1), 66-year-old woman (case 2), and 64-yearold man (case 3) who underwent unsuccessful MTP joint replacement of the great toe and presented to our clinic with pain at 15, 1, and 20 years postoperatively, respectively. Operative resection has been scheduled for case 1, whereas symptoms were managed nonoperatively in case 2. In case 3, operative removal …

Rare Tumors Adjacent To The Achilles Tendon: Report Of Two Cases, Jay J. Wojcik, Aditi S. Majumdar, Kathleen M. Madden, Richard A. Miller

UNM Orthopaedic Research Journal

Benign masses are not uncommon near the Achilles tendon of the ankle. However, the occurrence of angiomyomas or glomus tumors in the region has rarely been reported. We describe two patients, a 44-year-old woman and 44-yearold man, who presented with a tender mass posterior to the Achilles tendon. Excision led to successful removal of the lesion in both cases. Results of histological examinations revealed an angiomyoma and glomus tumor in the woman and man, respectively. Although rare, the presence of these tumors should be considered in the differential diagnosis of masses near the Achilles tendon.

Total Ankle Replacement, Then And Now: A Review, Katherine J. Gavin

UNM Orthopaedic Research Journal

Total ankle replacement (TAR) for treating end-stage osteoarthritis of the ankle joint has been evolving since the early 1960s. Increased understanding of the biomechanics and kinematics of the foot and ankle, postoperative results of implant use, and advances in technology have led to improved implant designs and treatment outcomes. The current study reviews associated historical perspectives, kinematics, biomechanics, patient selection, imaging procedures, modern surgical techniques, postoperative complications, and comparison studies with arthrodesis to help evaluate TAR in successfully treating osteoarthritis of the ankle joint. Although arthrodesis remains the gold standard for treatment, findings of new studies have suggested that TAR …

Antegrade Endosteal Fibular Strut Augmentation For Periprosthetic Femur Fracture Above Stemmed Total Knee Arthroplasty, Tyler Snoap, Jason Roberts, Matthew Jaykel

Research Day

Abstract Title: ANTEGRADE ENDOSTEAL FIBULAR STRUT AUGMENTATION FOR PERIPROSTHETIC FEMUR FRACTURE ABOVE STEMMED TOTAL KNEE ARTHROPLASTY Abstract ID: 245 Abstract Category: Clinical Research Introduction: 
The management of peri-prosthetics fracture around total knee replacements is technically challenging. The options for operative fixation become more limited if the femoral component is stemmed, which often is the case after revision arthroplasty procedures. The goals of surgery for peri-prosthetic fractures above knee replacements are to provide a rigid construct to promote healing, allow immediate knee range of motion, and allow weight bearing during the healing process. 
Purpose: 
The purpose of this study is to …
