BACKGROUND: Percutaneous pinning has been accepted as the "gold standard" for displaced supracondylar humeral fracture (SHF) in children. However, to secure an anatomic reduction and to reduce the rotated fragment, open reduction is often necessary when there is inadequate stabilization or a satisfactory reduction has failed to be achieved. The study aimed to compare the efficacy of the open reduction and bioabsorbable poly-d,l-lactic acid (PDLLA) pin fixation method with the closed reduction and lateral external fixation method in irreducible delayed Gartland type III SHF in children...

Cerebral Palsy (CP) is the leading cause of childhood motor disability, with a global incidence of 1.6 to 2.5/1,000 live births. Approximately 23% of children with CP are dependent upon assistive technologies. Some children with developmental disabilities have self-injurious behaviors such as finger biting but also have therapeutic needs. The purpose of this technical note is to describe design considerations for a protective glove and finger covering that maintains finger dexterity for children who exhibit finger and hand chewing (dermatophagia) and require therapeutic range of motion and may benefit from sensory stimulation resulting from constant contact between glove and skin...

Aging is a natural process characterized by several biological changes. In this context, oxidative stress appears as a key factor that leads cells and organisms to severe dysfunctions and diseases. To cope with reactive oxygen species and oxidative-related damage, there has been increased use of superoxide dismutase (SOD)/catalase (CAT) biomimetic compounds. Recently, we have shown that three metal-based compounds {[Fe(HPClNOL)Cl2]NO3, [Cu(HPClNOL)(CH3CN)](ClO4)2 and Mn(HPClNOL)(Cl)2}, harboring in vitro SOD and/or CAT activities, were critical for protection of yeast cells against oxidative stress...

In the field of bioabsorbable composites for biomedical applications, extrusion has been employed as a method to prepare homogeneous blends of polymeric matrices with bioactive ceramic fillers. In this work, the suitability of processing poly-l-lactic acid/Magnesium (PLLA/Mg) composites by hot extrusion has been assessed by a systematic characterization of PLLA/Mg composites containing different amounts of Mg particles up to 7wt%. The results show that extrusion causes a reduction of almost 20% in the viscosity average molecular weight of PLLA, which further decreases with increasing Mg content...

Drug-eluting stents (DES) have been shown to significantly reduce clinical and angiographic restenosis compared to bare metal stents (BMS). The polymer coatings on DES elute antiproliferative drugs to inhibit intimal proliferation and prevent restenosis after stent implantation. Permanent polymers which do not degrade in vivo may increase the likelihood of stent-related delayed arterial healing or polymer hypersensitivity. In turn, these limitations may contribute to an increased risk of late clinical events...

We compared the pullout strength of a suture-based anchor versus a bioabsorbable anchor in the distal fibula and calcaneus and evaluated the relationship between bone mineral density and peak load to failure. Eight paired cadaveric specimens underwent a modified Broström procedure and Achilles tendon reattachment. The fibula and calcaneus in the paired specimens received either a suture-based anchor or a bioabsorbable suture anchor. The fibular and calcaneal specimens were loaded to failure, defined as a substantial decrease in the applied load or pullout from the bone...

A new biodegradable coating was developed for bioabsorbable monofilament sutures. Specifically, a random copolymer having 35wt-% and 65wt-% of lactide and trimethylene carbonate units showed appropriate flexibility, stickiness and degradation rate, as well as capability to produce a complete and uniform coating. Monofilament sutures of polyglycolide-b-poly(glycolide-co-trimethylene carbonate-co-ε-caprolactone)-b-polyglycolide were loaded with chlorhexidine (CHX) and poly(hexamethylene biguanide) (PHMB) to explore the possibility to achieve antimicrobial activity without adverse cytotoxic effects...

We report the case of a patient who presented a pretibial extra-articular cyst two years after an arthroscopically assisted ACL reconstruction using an autologous bone-patellar tendon-bone graft. The tibial fixation was achieved with a bioabsorbable screw made of poly-L, D-lactic and -tricalcium phosphate (-TCP). A subcutaneous pseudocystic lesion was excised. It consisted of a capsular fibrous tissue with minimal milky fluid (1 ml) centrally. It penetrated into the tibial tunnel but did not communicate with the knee joint space...

AIMS: As more elderly and co-morbid patients require percutaneous revascularization, 1 year of dual-antiplatelet therapy (DAPT) becomes concerning. Synergy stents (Boston Scientific) allow for early cessation of DAPT. This study assessed those in our unit who underwent percutaneous coronary intervention (PCI) with a Synergy stent to examine a minimum of 6 months of clinical outcomes after early discontinuation of DAPT. METHODS AND RESULTS: All non-trial patients in our unit who had PCI with a Synergy stent from August 2013 to February 2016 were retrospectively analyzed...

Introduction. The radicular groove is a developmental groove which is usually found on the palatal or lateral aspects of the maxillary incisor teeth. The present case is a maxillary lateral incisor with a small second root and a deep radicular groove. The developmental groove caused a combined periodontal-endodontic lesion. Methods. Case was managed using a combined treatment procedure involving nonsurgical root canal therapy and surgical periodontal treatment. After completion of root canal treatment, guided tissue regeneration (GTR) was carried out using decalcified freeze dried bone allograft (DFDBA) and a bioabsorbable collagenous membrane...

BACKGROUND: The most common biliary complications after orthotopic liver transplantation are bile leaks, anastomotic and intrahepatic strictures, stones, and ampullary dysfunction. These complications can occur in up to 10% to 30% of liver transplant recipients. Leaks occur early in the posttransplant period; the stricture formation typically graduates over time. METHODS: Ten patients underwent transplantation in our preliminary study: 5 were randomized to the group with stent placement and 5 to the control group...

INTRODUCTION: Several bioresorbable plating systems have become standard in pediatric craniosynostosis reconstruction. A comparison of these systems is needed to aid surgeons in the preoperative planning process. The authors aim to evaluate 1 institution's experience using Resorb-X by KLS Martin and Delta Resorbable Fixation System by Stryker (Stryker Craniomaxillofacial, Kalamazoo, MI). METHODS: A sample of patients with single-suture nonsyndromic craniosynostosis treated at St Louis Children's Hospital between 2007 and 2014 using either Resorb-X or Delta bioresorbable plating systems were reviewed...

: Background Refractory cases of Achilles tendinopathy amenable to surgery may include reattachment of the tendon using suture anchors. However, there is paucity of information describing the optimal insertion angle to maximize the tendon footprint and anchor stability in the calcaneus. The purpose of this investigation is to compare the fixation strength of suture anchors inserted at 90° and 45° (the Deadman's angle) relative to the primary compressive trabeculae of the calcaneus. Methods A total of 12 matched pairs of adult cadaveric calcanei were excised and potted to approximate their alignment in vivo...

Biodegradable and bioabsorbable poly(lactic acid)s are one of the most important biomedical materials. However, it is difficult to introduce the functional groups into poly(lactic acid)s in order to improve their hydrophilicity and degradation rate. Here the authors describe the synthesis of functionalized cyclic lactide monomer 3,6-bis(benzyloxymethyl)-1,4-dioxane-2,5-dione (BnLA) using an advanced synthetic route. Water-soluble hydroxyl-functionalized homopoly(lactic acid) (P(OH)LA) is synthesized via ring-opening polymerization (ROP) of BnLA, followed by a hydrogenolytic deprotection reaction...

MAGNEZIX® (Syntellix AG, Hanover, Germany) is a biodegradable magnesium-based alloy (MgYREZr) which is currently used to manufacture bioabsorbable compression screws. To date, there are very few studies reporting on a limited number of elective foot surgeries using this innovative implant. This case report describes the application of this screw for osteochondral fracture fixation at the humeral capitulum next to a loose radial head prosthesis, which was revised at the same time. The clinical course was uneventful...
