BACKGROUND: SYNERGY, a bioabsorbable polymer-based, everolimus-eluting stent (BP-DES), recently received regulatory approval in the USA for use in percutaneous coronary interventions. Yet, information on the safety of BP-DES in routine clinical practice is limited. Our aim was to compare the safety of the recently approved BP-DES with current durable polymer drug-eluting stents (DP-DES) by analyzing adverse events, namely, stent thrombosis (ST), reported to the Manufacturer and User Facility Device Experience (MAUDE) database...

C Faldini, A Mazzotti, A Panciera, F Perna, N Stefanini, S Giannini
Flatfoot is a common condition in growing-age patients. Despite its common presentation, nowadays surgical indications and treatments are still debated. Arthroereisis is a widely used technique, and several implants designs have been proposed over time. Despite the good results shown in the literature, the main drawback of these techniques has always been the need for a second surgery for implant removal. Bioabsorbable devices have been introduced to overcome this necessity.Correct approach to the patient, indications and contraindications and available studies on bioabsorbable implants for subtalar arthroereisis in pediatric flatfoot were analyzed in this narrative review...

REVIEW
Eugene T Ek, Kemble Wang
Surgical treatment of ultrasmall proximal pole scaphoid fractures poses a number of challenges. The fragment may be too small to fix with conventional headless screw fixation owing to the high risk of fragmentation upon insertion. However, excision of the fragment risks compromising the scapholunate ligament complex and also exposes the radioscaphoid joint to potential degenerative changes. Under these circumstances, we describe the use of bioabsorbable osteochondral fixation nails that allows stable low-profile fixation while minimizing the risk of fracturing the proximal pole...

INTRODUCTION: There continues to be debate regarding the best surgical technique for the treatment of paraesophageal hernias. While laparoscopic and robotic approaches are widely employed around the world, the benefits of mesh use to reinforce hiatal closure are still not well established. The goal of this manuscript is to describe the currently available results with biologic and bioabsorbable meshes for treatment of paraesophageal hernias, particularly with reference to the rate of recurrence...

BACKGROUND: A long-term follow-up comparing double-bundle and single-bundle techniques for anterior cruciate ligament (ACL) reconstruction has not been reported before. HYPOTHESIS: Double-bundle ACL reconstruction may have fewer graft ruptures, lower rates of osteoarthritis (OA), and better stability than single-bundle reconstruction. STUDY DESIGN: Randomized controlled trial; Level of evidence, 2. METHODS: Ninety patients were randomized for double-bundle ACL reconstruction with bioabsorbable screw fixation (DB group; n = 30), single-bundle ACL reconstruction with bioabsorbable screw fixation (SBB group; n = 30), and single-bundle ACL reconstruction with metallic screw fixation (SBM group; n = 30)...

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...

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...
