Do New Trainees Pose A Threat To Postoperative Complications After Hip Fracture Surgeries? Retrospective Cohort Of 1045 Patients Over A Decade At A University Hospital, Obada Hasan, Mashal Amin, Umar Rabbani, Amna Rabbani, Fatima Mahmood, Shahryar Noordin

Department of Paediatrics and Child Health

Introduction: Induction of new residents and surgical trainees in most institutes occurs once a year. Fresh residents with no experience, may pose a threat to the surgical procedure outcome and there can be a potential increase in patients' morbidity and mortality as a result of this turnover. Literature is inconclusive about this effect. Our aim was to study the "new residents' induction effect" on postoperative complications after hip fracture surgeries.
Methodology: This is non funded non commercialized study from a university hospital. Investigators studied a retrospective cohort of 1045 adult hip fracture patients who were operated at our tertiary care …

Walking Kinematics In Young Children With Limb Loss Using Early Versus Traditional Prosthetic Knee Prescription Protocols, Mark Daniel Geil, Zahra Safaeepour, Brian Giavedoni, Colleen Coulter

Faculty Articles

The traditional treatment protocol for young children with congenital or acquired amputations at or proximal to the knee prescribes a prosthesis without a working knee joint, based in part on the assumption that a child learning to walk cannot properly utilize a passively flexing prosthetic knee component. An alternative to this Traditional Knee (TK) protocol is an “Early Knee” (EK) protocol, which prescribes an articulating prosthetic knee in the child’s first prosthesis, during development of crawling and transitioning into and out of upright positions. To date, no study has compared samples of children with limb loss at or proximal to …

Utilization Of A Continuous Pericapsular Nerve Group (Peng) Block With An Opioid-Sparing Repair Of A Femoral Neck Fracture In A Pediatric Patient, Karla Wyatt, Moustafa Zidane, Chyong-Jy Joyce Liu

Faculty, Staff and Students Publications

In the pediatric population, femoral neck fractures are usually associated with high-impact trauma and often present with pain in the groin area. Regional anesthesia can offer adjunctive therapy for acute pain management. Various techniques have been employed to circumvent pain related to hip fractures and resultant hip surgery. Neuraxial, lumbar plexus, caudal, epidural, fascia iliaca, and femoral continuous nerve block techniques are advantageous in mitigating hip pain. However, these approaches require patient repositioning during placement and carry the potential for motor blockade with resultant weakness. A newly described method, the Pericapsular Nerve Group (PENG) block, allows for analgesia of the …

What Is Congenital Talipes Equinovarus?, Cornelia Lieb-Lundell

San Marcos, Fall 2019

An estimated 80% of clubfoot cases occur in low to middle-income countries. Incidence of clubfoot is estimated to be 1-1.5 per 1000 births, and male to female occurrence is 3:1. (1) Left untreated, this congenital anomaly becomes a “neglected clubfoot” and can result in lifelong hardships including limited ambulation related to gait deviations, pain, foot deformities and an inability to wear shoes. Without treatment, this health condition can lead to functional limitations with limited independence in activities of daily living and participation restrictions within the family and community related to decreased mobility. (2)

The intervention presented is the main components …

Rigid Nail Fixation For Treatment Of Femur Fractures In Children Aged 6 To 12 Years: A Review, Brielle Payne Plost, David M. Bennett, Andrew W. Parsons, Matthew G. Wharton

UNM Orthopaedic Research Journal

Although femoral shaft fractures are common in children, treatment using rigid intramedullary nail fixation remains controversial owing to concerns of avascular necrosis (AVN) and disruption of growth of the proximal femur. We examined studies on AVN complications and proximal femur deformity after rigid nail fixation in children aged 6 to 12 years. Of the 13 studies included, nine had no incidents of AVN or clinically significant proximal femur deformity using a greater trochanter entry point. Four studies showed cases of AVN or proximal femoral deformity in patients treated with intramedullary nails through a starting point at or near the piriformis …

Accumulation of senescent cells over time contributes to aging and age-related diseases. However, what drives senescence in vivo is not clear. Here we used a genetic approach to determine if spontaneous nuclear DNA damage is sufficient to initiate senescence in mammals. Ercc1-/Δ mice with reduced expression of ERCC1-XPF endonuclease have impaired capacity to repair the nuclear genome. Ercc1-/Δ mice accumulated spontaneous, oxidative DNA damage more rapidly than wild-type (WT) mice. As a consequence, senescent cells accumulated more rapidly in Ercc1-/Δ mice compared to repair-competent animals. However, the levels of DNA damage and senescent cells in Ercc1-/Δ mice never exceeded that …

Manuscripts, Articles, Book Chapters and Other Papers

Purpose: Hemiepiphysiodesis has been widely used to correct angular deformity of long bone in immature patients. However, there is a limited knowledge about the biomechanical effect of this technique on the histopathological changes of the growth plate and the mechanism of recurrence of malformation after implant removal. We aimed to evaluate the biomechanical effect of hemiepiphysiodesis on the histopathological changes of the growth plate and the mechanism of recurrence of malformation after implant removal in Bama miniature pigs, and to explore the role of asymmetric stress during this procedure.

Methods: Eight 3-month-old male Bama miniature pigs sustained surgeries on the …

Biomechanical Evaluation Of A Growth-Friendly Rod Construct., Sarah Galvis, Josh Arnold, Erin Mannen, Benjamin Wong, Hadley Sis, Eileen Cadel, John Anderson, Dennis Anderson, Paul Arnold, Elizabeth Friis

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Distraction-type rods mechanically stabilize the thorax and improve lung growth and function by applying distraction forces at the rib, spine, pelvis, or a combination of locations. However, the amount of stability the rods provide and the amount the thorax needs is unknown.

METHODS: Five freshly frozen and thawed cadaveric thoracic spine specimens were tested for lateral bending, flexion/extension, and axial rotation in displacement control (1°/sec) to a load limit of ±5 Nm for five cycles after which a growth-friendly unilateral rod was placed in a simulated rib-to-lumbar attachment along the right side. The specimens were tested again in the …

The Effect Of Bony Parameters On The Pediatric Knee: Normal Versus Anterior Cruciate Ligament Injury Versus Tibial Spine Avulsion Fracture., Kenneth A. Shaw, Brian S. Dunoski, Neil J. Mardis, Donna M. Pacicca

Manuscripts, Articles, Book Chapters and Other Papers

Purpose  Anterior cruciate ligament (ACL) injuries can present as a ligamentous disruption or avulsion fracture of the tibial spine in pediatric patients. Differences in knee morphometric parameters have been investigated between pediatric cohorts with ACL disruptions and tibial spine avulsion fractures. However, no study to date has compared morphometric parameters in patients with tibial spine avulsion fracture against a control population. Methods  A retrospective review of pediatric patients undergoing knee magnetic resonance imaging (MRI) studies was performed, identifying 15 patients with tibial spine avulsion fracture between January 1, 2009, and January 1, 2013. Inclusionary criteria consisted of patients who sustained …

Childhood chronic kidney disease (CHD) poses multiple threats to bone accrual; however, the associated fracture risk is not well characterized. This prospective cohort study included 537 CKD in Children (CKiD) participants. Fracture histories were obtained at baseline, at years 1, 3, and 5 through November 1, 2009, and annually thereafter. We used Cox regression analysis of first incident fracture to evaluate potential correlates of fracture risk. At enrollment, median age was 11 years, and 16% of patients reported a prior fracture. Over a median of 3.9 years, 43 males and 24 females sustained incident fractures, corresponding to 395 (95% confidence …

The Relationship Between Foot Arch Measurements And Walking Parameters In Children, Simone V. Gill, Sara Keimig, Damian Kelty-Stephen, Ya-Ching Hung, Jeremy M. Desilva

Publications and Research

Background: Walking mechanics are influenced by body morphology. Foot arch height is one aspect of body morphology central to walking. However, generalizations about the relationship between arch height and walking are limited due to previous methodologies used for measuring the arch and the populations that have been studied. To gain the knowledge needed to support healthy gait in children and adults, we need to understand this relationship in unimpaired, typically developing children and adults using dynamic measures. The purpose of the current study was to examine the relationship between arch height and gait in a sample of healthy children …

The Effect Of Scoliotic Deformity On Spine Kinematics In Adolescents., Sarah Galvis, Douglas Burton, Brandon Barnds, John Anderson, Richard M. Schwend, Nigel Price, Sara Wilson, Elizabeth Friis

Manuscripts, Articles, Book Chapters and Other Papers

Background: While adolescent idiopathic scoliosis (AIS) produces well characterized deformation in spinal form, the effect on spinal function, namely mobility, is not well known. Better understanding of scoliotic spinal mobility could yield better treatment targets and diagnoses. The purpose of this study was to characterize the spinal mobility differences due to AIS. It was hypothesized that the AIS group would exhibit reduced mobility compared to the typical adolescent (TA) group.

Methods: Eleven adolescents with right thoracic AIS, apices T6-T10, and eleven age- and gender-matched TAs moved to their maximum bent position in sagittal and coronal plane bending tasks. A Trakstar …

© 2015, The Author(s).

Study design: Retrospective, case–control.

Purpose: Knee morphometric risk factors for noncontact anterior cruciate ligament (ACL) injury have been a popular topic with skeletally mature patients. Little research has focused on the skeletally immature, with conflicting conclusions. This study performs a comprehensive analysis of identified parameters thought to predispose to ACL injury in a skeletally immature cohort.

Methods: A retrospective review of pediatric patients undergoing knee magnetic resonance imaging (MRI) was performed over a 4-year period. Inclusionary criteria included mid-substance ACL disruption, skeletal immaturity, noncontact injury, without associated ligamentous disruption, and no medical condition associated with ligamentous …

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, …

Well Leg Compartment Syndrome: The Debit Side Of Hemilithotomy Position, Shahryar Noordin, Salim Allana, Muhammad Abdul Wajid

Section of Orthopaedic Surgery

We describe a case of well leg compartment syndrome following unilateral lithotomy position in a patient undergoing contralateral antegrade intramedullary femoral nailing. Following two-incision four compartment fasciotomy, the patient recovered with no residual defects. We dissuade use of the hemilithotomy position for antegrade femoral nailing procedures in favour of another previously described position, because this predisposes patients to position-associated complications without offering any substantial advantage.
