J Long Term Eff Med Implants 2018 ;28(2):161-168

Biomedical Engineering Program, School of Graduate Studies, SUNY Downstate Medical Center, 450 Clarkson Avenue, Box 30, Brooklyn, NY 11203; Departments of Orthopedic Surgery and Rehabilitation Medicine, Neurosurgery, Physiology, and Pharmacology, SUNY Downstate Medical Center, 450 Clarkson Avenue, Box 30, Brooklyn, NY 11203.

The aim of this study was relative variation quantification of the total electric field (EF) sum in a region very close to a dental root of the first molar tooth for two different materials: dentine (before implantation) and titanium (present in a screw after implantation), due to development of electrical charges generated by chewing force on the tooth. Because bone is a piezoelectric material, mechanical strain that is generated by chewing force on bone adjacent to the dental root produces electrical charges. Relative variations in the EF sum values with distance of nodes from the centerline of the root was observed for both cases and studied for two different boundary voltage conditions. Read More

J Long Term Eff Med Implants 2018 ;28(2):79-85

Department of Orthopedic Surgery and Biomedical Engineering, University of Tennessee Health Science Center, Memphis, TN; Campbell Clinic Orthopedics, Germantown, TN.

Increased joint laxity is associated with excessive polyethylene wear, but the correlation between laxity and metal wear has not been established. Fifteen necropsy-retrieved primary total knee replacements were mounted into a custom knee-testing machine that measured anterior-posterior, varus-valgus, and internal-external rotational laxity at 0°, 30°, 60°, and 90° of flexion. Inductively coupled plasma-mass spectrometry analysis was performed to measure the cobalt (Co), chromium (Cr), and titanium (Ti) concentrations in periprosthetic tissue samples. Read More

Presence of Biofilms on Polyurethane-Coated Breast Implants: Preliminary Results.

J Long Term Eff Med Implants 2016 ;26(3):237-243

Center for Septic Surgery and Infectious Diseases, Center for Musculoskeletal Surgery, Charite-University Medicine Berlin, Berlin, Germany.

Polyurethane-coated breast implants seem to be associated with lower medium- and long-term capsular contracture rates in comparison to textured or smooth implant surfaces. Although the etiology of capsular contracture is uncertain, bacterial biofilms have been suggested to trigger chronic peri-implant inflammation, eventually leading to capsular contracture. It is unknown whether polyurethane-coated implants are less prone to biofilm colonization than other implant surfaces. Read More

Upper Extremity Nerve Function and Pain in Human Volunteers with Narrow versus Wide Tourniquets.

J Long Term Eff Med Implants 2016 ;26(2):173-181

Rubin Institute for Advanced Orthopedics, Sinai Hospital of Baltimore, Baltimore, MD.

Nerve injury is a serious potential complication associated with clinical use of tourniquets during surgery. A novel narrow, single-use silicon ring tourniquet has been introduced, which may cause less nerve compression and provide a larger field of surgical exposure than standard wide tourniquets. We investigated both types of tourniquets in the non-dominant proximal upper arm of 15 healthy human volunteers. Read More

A Biomechanical Comparison of Different Tendon Repair Techniques.

J Long Term Eff Med Implants 2016 ;26(2):167-171

Department of Orthopaedic Surgery and Rehabilitation Medicine, SUNY Downstate Medical Center, Brooklyn, NY.

Previous studies have examined multiple suture techniques for the repair of ruptured tendons. In this study, we investigated how the two- and four-stranded Krackow suture weave techniques compared with a novel Krackow/Bunnell suture technique. Our hypothesis was that the Krackow/Bunnell suture would have greater strength compared with the two- and four-stranded Krackow suture in terms of resistance to pullout from the muscle tendon.

Astym® Therapy for the Management of Recalcitrant Knee Joint Stiffness after Total Knee Arthroplasty.

J Long Term Eff Med Implants 2016 ;26(2):151-159

Center for Joint Preservation and Replacement, Rubin Institute for Advanced Orthopedics, Sinai Hospital of Baltimore, Baltimore, Maryland.

Knee stiffness is a common complication after total knee arthroplasty (TKA). Despite studies published on the surgical management of reduced range of motion (ROM) after TKA, there is limited evidence on the nonoperative management of joint and soft tissue imbalances possibly contributing to reduced knee ROM. This report assesses changes in ROM, pain, function, and patellar tendon length after Astym® joint mobilization use. Read More

A Cost-Effective Technique for Spinal Instrumentation in the Treatment of Adolescent Idiopathic Scoliosis.

J Long Term Eff Med Implants 2016 ;26(2):143-149

Department of Orthopaedic Surgery, Medical College of Georgia-Augusta University, Augusta, GA.

Surgical treatment for adolescent idiopathic scoliosis (AIS) has evolved over the past decades to the point where instrumented arthrodesis with all pedicle screw and rod constructs is commonplace. Although these constructs provide superb correction and fixation, their financial burden is substantial. Here, we present a more cost-effective technique using a combination of pedicle screws (serving as the construct base), a sagittal precontoured unit rod, and sublaminar wires to provide segmental correction for the surgical treatment of AIS.

Osteoinductive Activity of DFDBA Materials versus Growth Factors on Gene Expression of MG-63 Cells: An In Vitro Study.

J Long Term Eff Med Implants 2016 ;26(2):133-142

School of Dentistry, Shahid Beheshti University of Medical Sciences, Tehran, Iran.

Guided bone regeneration using demineralized freeze-dried bone allograft (DFDBA) and growth factors (GFs) is a current goal in implant dentistry because of their potential osteoinductive abilities. Regarding controversial results, the purpose of this study was to compare the osteoinductivity of three different DFDBAs from two different banks with two different GFs: transforming growth factor-beta (TGF-β) and platelet-derived growth factor (PDGF). MG-63 osteoblast-like cells were exposed to two different concentration of commercial DFDBAs (10 and 20 mg/mL) and growth factors (5 and 10 ng/mL). Read More

The Gelweave Valsalva Graft to Better Reconstruct the Anatomy of the Aortic Root.

J Long Term Eff Med Implants 2016 ;26(2):97-121

Department of Surgery, Faculty of Medicine, Laval University, Quebec, QC, Canada; Axe Medecine Regeneratrice, Centre de Recherche du CHU, Quebec, QC, Canada.

The Bentall procedure introduced in 1968 represents an undisputed cure to treat multiple pathologies involving the aortic valve and the ascending thoracic aorta. Over the years, multiple modifications have been introduced as well as a standardized approach to the operation with the goal to prevent long-term adverse events. The Gelweave Valsalva graft provides a novel manner to more efficiently reconstruct the anatomy of the aortic root either with a valve-sparing procedure or with the implantation of a valved conduit (bioprosthesis or mechanical valve).
