Minimally Invasive Lateral Lumbar Interbody Fusion With Direct Psoas Visualization, P. S. Yuan, K. Rowshan, R. B. Verma, L. E. Miller, J. E. Block

Journal Articles

Background: Minimally invasive lateral approaches to the lumbar spine have been adopted to allow access to the intervertebral disc space while avoiding the complications associated with anterior or posterior approaches. This report describes a minimally invasive technique for lateral lumbar interbody fusion LLIF that allows direct intraoperative visualization of the psoas and surrounding neurovasculature (DV-LIF). Methods: The technique utilizes a radiolucent tubular retractor and a secondary psoas retractor that allows a muscle-sparing approach while offering excellent visualization of the operative site. The unique advantage of this procedure is that the psoas muscle and surrounding nerves can be directly visualized intraoperatively …

Postoperative SSIs are believed to occur via bacterial inoculation at the time of surgery or as a result of bacterial contamination of the wound via open pathways to the deep tissue layers.^1–3 The probability of SSI is reflected by interaction of parameters that can be categorized into three major groups.² The first group consists of factors related to the ability of bacteria to cause infection and include initial inoculation load and genetically determined virulence factors that are required for adherence, reproduction, toxin production, and bypassing host defense mechanisms. The second group involves those factors related to the defense …

Controversial Issues In Kyphoplasty And Vertebroplasty In Osteoporotic Vertebral Fractures, Ioannis D. Papanastassiou, Andreas Filis, Maria A. Gerochristou, Frank D. Vrionis

Orthopaedics and Sports Medicine Faculty Publications

Kyphoplasty (KP) and vertebroplasty (VP) have been successfully employed for many years for the treatment of osteoporotic vertebral fractures. The purpose of this review is to resolve the controversial issues raised by the two randomized trials that claimed no difference between VP and SHAM procedure. In particular we compare nonsurgical management (NSM) and KP and VP, in terms of clinical parameters (pain, disability, quality of life, and new fractures), cost-effectiveness, radiological variables (kyphosis correction and vertebral height restoration), and VP versus KP for cement extravasation and complications profile. Cement types and optimal filling are analyzed and technological innovations are presented. …

Low Back Pain Beliefs Are Associated To Age, Location Of Work, Education And Pain-Related Disability In Chinese Healthcare Professionals Working In China: A Cross Sectional Survey, B K. Tan, Anne J. Smith, Peter B. O'Sullivan, Gang Chen, Angus F. Burnett, Andrew M. Briggs

Research outputs 2014 to 2021

Background: Low back pain (LBP) is the leading cause of disability worldwide. Evidence pointing towards a more efficacious model of care using a biopsychosocial approach for LBP management highlights the need to understand the pain-related beliefs of patients and those who treat them. The beliefs held by healthcare professionals (HCPs) are known to influence the treatment advice given to patients and consequently management outcomes. Back pain beliefs are known to be influenced by factors such as culture, education, health literacy, place of work, personal experience of LBP and the sequelae of LBP such as disability. There is currently a knowledge …

Evaluation Of Tissue-Engineered Tendon Enthesis Polymer Constructs, Joshua A. Bundy Bs, Mary Beth Wade Phd, Hitomi Nakao Md, Phillip Mcclellan Phd, Qing Yu Phd, Robin Jacquet-Childs Ms, William J. Landis Phd

Williams Honors College, Honors Research Projects

Both scientists and clinicians have proposed tissue engineering as the future of medicine. The possibilities for tissue engineering, that is, fabrication of tissues and organs in the laboratory and their translation to patients, appear to be endless, and many believe that this new approach in medicine will result in abolishing many common ailments, injuries, and congenital defects. Injuries to a tendon enthesis, the normal tissue connection between tendon and bone, are of particular concern to clinicians because of their frequency and failure to repair as a result of surgery. While these injuries may not be life threatening, they can certainly …

Treatment Of Hallux Valgus With A Chevron Osteotomy Combined With A Lateral Release, Selina Silva, Richard A. Miller

UNM Orthopaedic Research Journal

Purpose: Current literature recommends proximal first metatarsal osteotomy for large hallux valgus deformities. Combined distal osteotomy with lateral release can be done and may provide a similar degree of correction. The concern with this technique is disruption of the blood supply to the first metatarsal head. We hypothesized that a chevron osteotomy in conjunction with a lateral release is effective in correcting some larger hallux valgus deformities without causing disruption of the blood supply to the first metatarsal head.

Methods: We reviewed the imaging studies of fortysix cases that underwent a distal chevron osteotomy with lateral release for correction of …

Within-Day Test-Retest Reliability Of Transcranial Magnetic Stimulation Measurements Of Corticomotor Excitability For Gastrocnemius And Tibialis Anterior Muscles, Beth E. Fisher, Ya-Yun Lee, Todd E. Davenport, Stephen F. Reischl, Elizabeth Ruckert, Kornelia Kulig

School of Pharmacy Faculty Articles

Background: Manual therapy interventions targeting the talocrural joint can improve gait and balance functions in individuals following ankle sprains. Less is known about the underlying mechanisms of functional improvements after manual therapy. One hypothesis involves change in corticomotor excitability (CE) following manual therapy procedures. Transcranial magnetic stimulation (TMS) is a brain imaging method that could provide important information regarding potential changes in CE associated with manual therapy techniques applied to the talocrural joint. However, within-day reliability of TMS to measure CE must first be established in order to measure CE changes associated with manual therapy procedures.

Objective: To determine the …

Boning Up On Autophagy: The Role Of Autophagy In Skeletal Biology., Irving Shapiro, Robert Layfield, Martin Lotz, Carmine Settembre, Caroline Whitehouse

Department of Orthopaedic Surgery Faculty Papers

From an evolutionary perspective, the major function of bone is to provide stable sites for muscle attachment and affording protection of vital organs, especially the heart and lungs (ribs) and spinal cord (vertebrae and intervertebral discs). However, bone has a considerable number of other functions: serving as a store for mineral ions, providing a site for blood cell synthesis and participating in a complex system-wide endocrine system. Not surprisingly, bone and cartilage cell homeostasis is tightly controlled, as is the maintenance of tissue structure and mass. While a great deal of new information is accruing concerning skeletal cell homeostasis, one …

Differential Effects Of Fatigue On Movement Variability, N. Cortes, J. Onate, S. Morrison

Rehabilitation Sciences Faculty Publications

When individuals perform purposeful actions to fatigue, there is typically a general decline in their movement performance. This study was designed to investigate the effects exercise-induced fatigue has on lower limb kinetics and kinematics during a side-step cutting task. In particular, it was of interest to determine what changes could be seen in mean amplitude and all metrics of signal variability with fatigue. The results of the study revealed that post-fatigue there was an overall decrease in absolute force production as reflected by a decline in mean amplitude and variability (SD) of the ground reaction forces (GRF_V and GRF …

Efficacy Of A Novel Examination Maneuver In Diagnosing Meniscal Pathology, Eric J. Freeh, Ryan Lurtsema

UNM Orthopaedic Research Journal

In this retrospective study we examine the effectiveness of the here named “Twist test” in diagnosing meniscal pathology. In preparation for this study, a literature review was conducted to look at commonly used “gold standard” exam maneuvers utilized in the diagnosis of meniscal lesions. The data from these studies was used as comparisons against the twist test. Medical records of patients who underwent knee arthroscopy from the 2013 calendar year were pulled and assessed for positive or negative Twist test results. These results were then correlated with Magnetic Resonance Imaging (MRI), and more definitively, arthroscopic findings. With this data, we …
