Combined Anteversion Technique for Total Hip Arthroplasty With Handheld Accelerometer-Based Navigation System

Autor: Diego Alarcon Perico, MD, Christopher N. Warne, MD, Sheng-Hsun Lee, MD, Heather J. Roberts, MD, Rafael J. Sierra, MD

Publikováno v: Arthroplasty Today, Vol 23, Iss , Pp 101193- (2023)

Aiming for a combined cup and stem anteversion within a target range is one way to assess appropriate prosthetic component orientation and restoration of functional range of motion. We describe a surgical technique that allows the surgeon to assess t

Linoleic acid improves PIEZO2 dysfunction in a mouse model of Angelman Syndrome

Autor: Luis O. Romero, Rebeca Caires, A. Kaitlyn Victor, Juanma Ramirez, Francisco J. Sierra-Valdez, Patrick Walsh, Vincent Truong, Jungsoo Lee, Ugo Mayor, Lawrence T. Reiter, Valeria Vásquez, Julio F. Cordero-Morales

Publikováno v: Nature Communications, Vol 14, Iss 1, Pp 1-20 (2023)

Angelman syndrome (AS) is a neurogenetic disorder. Here, the authors found that PIEZO2 activity is reduced in sensory neurons from a mouse model of AS and used a linoleic acid-enriched diet to enhance PIEZO2 function and ameliorate AS-associated gait

Experimental study of an asymmetric valveless pump to elucidate insights into strategies for pediatric extravascular flow augmentation

Autor: J. Anatol, M. García-Díaz, C. Barrios-Collado, J. A. Moneo-Fernández, M. Horvath, T. Parra, F. Castro-Ruiz, E. T. Roche, J. Sierra-Pallares

Publikováno v: Scientific Reports, Vol 12, Iss 1, Pp 1-9 (2022)

Abstract Asymmetric pumping is a sub-category of valveless pumping in which a flexible tube is rhythmically compressed in the transverse symmetry plane. Due to the resulting asymmetry between the suction and discharge pipes, a net pumping head is ach

Dislocated and Dissociated Dual-Mobility Components Are Easily Missed and More Than Half Fail Closed Reduction

Autor: Katherine E. Mallett, MD, Michael J. Taunton, MD, Matthew P. Abdel, MD, Rafael J. Sierra, MD

Publikováno v: JBJS Open Access, Vol 8, Iss 3 (2023)

Background:. Dual-mobility (DM) implants reduce the risk of dislocation in patients who have undergone total hip arthroplasty (THA); however, DM implants are at risk for large-head dislocation and intraprosthetic dissociation (IPD), where the inner f

Scar Perception After Two Surgical Approaches for Total Hip Arthroplasty

Autor: Jacob M. Wilson, MD, Stephen M. Petis, MD, FRCSC, Mark W. Pagnano, MD, Rafael J. Sierra, MD, Robert T. Trousdale, MD, Michael J. Taunton, MD

Publikováno v: Arthroplasty Today, Vol 14, Iss , Pp 96-99 (2022)

Background: There is a paucity of literature examining patients’ and health-care providers’ perception of surgical scars after total hip arthroplasty (THA). This study examined perception of surgical scars after direct anterior (DAA) or posterior

Hip decompression combined with bone marrow concentrate and platelet-rich plasma for corticosteroid-induced osteonecrosis of the femoral head: mid-term update from a prospective study

Autor: Matthew T. Houdek, Cody C. Wyles, John-Rudolph H. Smith, Andre Terzic, Atta Behfar, Rafael J. Sierra

Publikováno v: Bone & Joint Open, Vol 2, Iss 11, Pp 926-931 (2021)

Aims: Bone marrow-derived mesenchymal stem cells obtained from bone marrow aspirate concentrate (BMAC) with platelet-rich plasma (PRP), has been used as an adjuvant to hip decompression. Early results have shown promise for hip preservation in patien

A parametric study of the effect of leading edge spherical tubercle amplitudes on the aerodynamic performance of a 2D wind turbine airfoil at low Reynolds numbers using computational fluid dynamics

Autor: D. Benavides Zadorozhna, O. Benavides, J. Sierra Grajeda, S. Figueroa Ramirez, L. de la Cruz May

Publikováno v: Energy Reports, Vol 7, Iss , Pp 4184-4196 (2021)

The majority of wind power is currently produced on high wind speed sites by large wind turbine, whereas small wind turbines often operate in light wind conditions. Small capacity wind turbines have not received the same engineering attention as thei
