Arthroereisis of the subtalar joint is a common surgical technique in Europe for the management of flexible flatfoot in the pediatric population. In most cases, it is performed using a calcaneo-stop metallic screw. Despite the good clinical results, screw removal is always advised after 2 to 3 years. The use of a bioabsorbable screw might overcome the need for a second operation to remove a nonabsorbable device. We report the results of a biodegradable calcaneo-stop screw at a minimum of 4 years of follow-up...

BACKGROUND: Although standard fixation of proximal interphalangeal (PIP) arthrodesis by K-wire is relatively inexpensive and well established, it does have some drawbacks, making newer fixation devices interesting. The aim of this study was to clinically and radiologically assess the operative correction of the lesser toe deformation in the form of a PIP arthrodesis using a bioabsorbable 2.7-mm fixation screw. METHODS: From January 2011 until October 2013, 34 patients underwent a PIP arthrodesis using the TRIM-IT (Arthrex) 2...

Poly(butylene adipate-co-terephthalate) (PBAT) was first chemically modified via free radical grafting with maleic anhydride (MA) and the MA-g-PBAT graft copolymer was then used as a matrix material to obtain cellulose nanocrystal (CNC)-reinforced MA-g-PBAT bio-nanocomposites via reactive extrusion process to accelerate efforts to develop functional bioabsorbable polymer nanocomposites with improved properties. The molecular structure of the PBAT after chemical modification with maleic anhydride was confirmed by 1H NMR and FTIR spectroscopy...

BACKGROUND: The omission of postoperative chest tube drainage may contribute to early recovery after thoracoscopic major lung resection; however, a validation study is necessary before the dissemination of a selective drain policy. METHODS: A total of 162 patients who underwent thoracoscopic anatomical lung resection for lung tumors were enrolled in this study. Alveolar air leaks were sealed with a combination of bioabsorbable mesh and fibrin glue. The chest tube was removed just after the removal of the tracheal tube in selected patients in whom complete pneumostasis was obtained...

BACKGROUND: Postoperative wound healing after endoscopic sinus surgery (ESS) in patients with chronic rhinosinusitis (CRS) is an important factor in procedural success. Local steroids and separation of opposing mucosa are commonly implemented to optimize healing. A bioabsorbable, fluticasone propionate (FP)-eluting implant, SinuBand FP, was assessed for its safety and efficacy when used in patients with CRS and nasal polyps, who were indicated for ESS including bilateral anterior and posterior ethmoidectomy...

INTRODUCTION: Prognathism is a common skeletal facial abnormality, associated with class III malocclusion, often with repercussions in quality of life. In addition to orthodontic treatment, sagittal split ramus osteotomy is the most common technique for its correction, and segment osteosynthesis is an important element of the post-surgical outcome. MATERIALS AND METHODS: A search for relevant literature was conducted in the PubMed/MEDLINE database and in other relevant sources...

Recently, adipose tissue has been regenerated by combining scaffolds, growth factors, and/or adipose tissue-derived stromal cells (ASCs). However, the safety of growth factors and ASCs has not been confirmed in cancer patients. We reported the regeneration of adipose tissue in the internal space of a polypropylene mesh containing a collagen sponge (CS), without using any growth factors or cells. We herein explored the formation of adipose tissue, using the bioabsorbable implant containing CS, in rats. We prepared the implants without and with CS, using threads of either poly l-lactide-co-ε-caprolactone [P(LA/CL)] or poly-l-lactic acid (PLLA), and measured their strengths...

BACKGROUND/PURPOSE: Bioabsorbable vascular scaffolds (BVS) are made from a radiolucent material. Their multiple implantations on a single long diffused segment requires a specific technique with imaging magnification, which could cause an increase in dose delivered during percutaneous coronary intervention (PCI) procedure. We aimed to identify differences in radiation dose, fluoroscopy and procedural times in Hybrid DES+ multiple BVS (Absorb, Abbott Inc., USA) implantation (hybrid metal/scaffold jacket) versus multiple III generation Drug-eluting stents (DES) (full-metal jacket) in patients with long and diffuse coronary artery disease of the left anterior descending (LAD) coronary artery...

Percutaneous transluminal coronary angioplasty with coronary stent implantation is a life-saving medical procedure that has become, nowadays, the most frequent performed therapeutic procedure in medicine. Plain balloon angioplasty, bare metal stents, first and second generation drug-eluting stents, bioresorbable and bioabsorbable scaffolds have offered diachronically a great advance against coronary artery disease and have enriched our medical armamentarium. Stented areas constitute vulnerable sites for endothelial damage, endothelial dysfunction, flow turbulence, hemorheologic changes, platelet dysfunction, coagulation changes and fibrinolytic disturbances...

The aim of this report is to analyse trends in Italian cathlab activity between 2010 and 2015. Data were obtained from the national database of the Italian Society of Interventional Cardiology (GISE), which includes 97% of Italian cardiac catheterisation laboratories. The number of percutaneous coronary interventions (PCI) has remained relatively stable in the past five years. We have observed a significant increase in the number of primary PCI (pPCI) from 471.5 to 557.5 per million inhabitants with a consequent reduction of rescue primary PCI/fibrinolysis...

Interventional cardiology in Denmark has been carried out since the mid 1980s. Interventional cardiology is only performed at a few high-volume centres. Healthcare coverage is universal and is essentially free of charge. Hospitals are mostly publicly owned and financed by fixed budgets and, in part, an activity-based funding system. Approximately 30,000 coronary angiographies (CAG), 10,000 percutaneous coronary interventions (PCIs) of which approximately 25% are primary PCIs, and 500 transcatheter aortic valve implantations (TAVIs) are carried out each year...

BACKGROUND: Zygoma fracture is of clinical importance because malar prominence plays an essential role in facial appearance. Traditionally, most maxillofacial surgeons perform osteosynthesis with titanium plates and screws for rigid fixation. However, this procedure has certain disadvantages that include the possibility of implant exposure, palpability or loosening of the screws, painful irritation, temperature sensitization, and radiographic artifacts. In this study, we compared the function and satisfaction outcome between Bonamates(®) bioabsorbable implant and Leibinger titanium implant...
