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

Use of Combined Magnetic Field Treatment for Fracture Nonunion.

J Long Term Eff Med Implants 2016 ;26(3):277-284

The Orthopedic Clinic Association, Phoenix, Arizona.

The use of noninvasive bone growth stimulators is a nonoperative treatment option for fracture nonunions. The purpose of this study was to evaluate the initial effectiveness of the combined magnetic field (CMF) bone growth stimulation in the treatment of fracture nonunions. Using data from a large nonunion fracture registry, we reviewed fracture-healing-outcome data and healing times for all patients treated with a CMF bone growth stimulator during a 4-yr period.

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

Evaluation of Alveolar Crest Changes following Buccal Bone Overbuilding in Immediate Implantation.

J Long Term Eff Med Implants 2016 ;26(3):217-224

Oral and Maxillofacial Research Center, Mashhad University of Medical Sciences, Mashhad, Iran.

The aim of the present study was to evaluate alveolar crest changes when using demineralized freeze-dried bone allograft (DFDBA) and resorbable membrane between flap and buccal bone in addition to filling the gap, as compared to merely filling the gap, when performing immediate implantation. In 18 patients with 24 single-root teeth, implants were placed immediately after extraction. In the test group (nine patients with 12 teeth), DFDBA and barrier membrane were placed between buccal crest and flap after implant placement. Read More

Do Prior Intra-Articular Corticosteroid Injections or Time of Administration Increase the Risks of Subsequent Periprosthetic Joint Infections after Total Knee Arthroplasty?

J Long Term Eff Med Implants 2016 ;26(3):191-197

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

Intra-articular injections of corticosteroids have been used as a treatment option for degenerative arthritis of the knee for short- to mid-term symptomatic pain relief for many decades. Recently, there have been studies that have reported increased risks of periprosthetic joint infections in patients who have received these injections. In this study, we evaluated the risk of superficial, deep, and overall rate of infections in 302 patients who had received intra-articular corticosteroid infiltration within 12 months before undergoing total knee arthroplasty (TKA) and compared them with a 1:1 matched cohort who had undergone TKA, but who did not have any prior corticosteroid knee injections.

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

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.
