1Distal radius volar rim plate: Technical and radiographic considerations显示文摘AIM To determine technical considerations and radiographic outcomes of the Synthes volar rim distal radius plate to treat complex intra-articular fractures. METHODS This review highlights technical considerations learnt using this implant since it was introduced in a major trauma unit in November 2011, including anatomical reduction and whether this was maintained radiographically. RESULTS Twenty-six of the 382 internally fixed distal radial fractures at our unit(6.8%) were deemed to require this plate in order to achieve optimal fracture fixation between November 2011 and May 2014. A further dorsal and/or radial plate was necessary in 35% and variable angle screws were used in 54% of cases. Postoperatively, mean radial height, inclination, volar tilt and ulnar variance restored were 11.7 mm, 21o, 4.3o and-1.2 mm respectively. There were no cases of non-union or flexor/extensor tendon rupture; one case of loss of fracture reduction. Overall incidence of plate removal was 15% with one plate removed for flexor and one for extensor tendon irritation CONCLUSION The use of a rim plate enables control of challenging fardistal fracture patterns. However, additional plates were required to improve and maintain reduction. Variable angle screws were necessary in half the cases to avoid intra-articular screw penetration. If used judiciously, this implant can achieve stable fixation despite the complexity of the fracture pattern.Michelle Spiteri Darren Roberts Wayne Ng Jamie Matthews Dominic Power 2017World Journal of Orthopedics2017,8,7:3

9Evaluation of nutrient stoichiometric relationships among ecosystem compartments of a subtropical treatment wetland. Do we have “Redfield wetlands”?显示文摘Background:Evaluation of carbon(C),nitrogen(N),and phosphorus(P)ratios in aquatic and terrestrial ecosystems can advance our understanding of biological processes,nutrient cycling,and the fate of organic matter(OM)in these ecosystems.Eutrophication of aquatic ecosystems can change the accumulation and decomposition of OM which can alter biogeochemical cycling and alter the base of the aquatic food web.This study investigated nutrient stoichiometry within and among wetland ecosystem compartments(i.e.,water column,flocculent,soil,and aboveground vegetation biomass)of two subtropical treatment wetlands with distinct vegetation communities.Two flow-ways(FWs)within the network of Everglades Stormwater Treatment Areas in south Florida(USA)were selected for this study.We evaluated nutrient stoichiometry of these to understand biogeochemical cycling and controls of nutrient removal in a treatment wetland within an ecological stoichiometry context.Results:This study demonstrates that C,N,and P stoichiometry can be highly variable among ecosystem compartments and between FWs.Power law slopes of C,N,and P within surface water floc,soil,and vegetation were significantly different between and along FWs.Conclusions:Assessment of wetland nutrient stoichiometry between and within ecosystem compartments suggests unconstrained stoichiometry related to P that conforms with the notion of P limitation in the ecosystem.Differences in N:P ratios between floc and soil suggest different pathways of organic nutrient accumulation and retention between FWs.Surface nutrient stoichiometry was highly variable and decoupled(or close to decoupled as indicated by<25%explained variation between parameters),in particular with respect to P.We hypothesize that decoupling may be the imprint of variability in inflow nutrient stoichiometry.However,despite active biogeochemical cycles that could act to restore nutrient stoichiometry along the FW,there was little evidence that such balancing occurred,as the degree of stochiometric decoupling in the water column did change with distance downstream.This information is only the beginning of a larger journey to understand stoichiometric processes within wetland ecosystems and how they relate to ecosystem function.Paul Julian II Stefan Gerber Rupesh K.Bhomia Jill King Todd Z.Osborne Alan L.Wright Matthew Powers Jacob Dombrowski 2019Ecological Processes2019,8,1:1
