Natuurakkers in het Buytenland : bedrijfsconcepten voor het samengaan van natuur en akkerbouw
In de Albrandswaard wordt de komende jaren door de provincie Zuid-Holland een natuur- en recreatiegebied van ongeveer 600 ha in omvang ontwikkeld, getiteld 'Landschapspark Buytenland'. Dit in het kader van de PKB Mainport ontwikkeling Rotterdam. De provincie Zuid-Holland heeft nu aan LEI, Alterra en CLM gevraagd om enkele bedrijfsconcepten te ontwikkelen voor 'natuurakkers'. Het gaat hierbij om de concepten voor het samengaan van akkerbouw en natuur onder regie van de akkerbouwer. Deze studie geeft inzicht in de wijze waarop natuurakkers in het Landschapspark Buytenland kunnen worden vormgegeven als levensvatbaar bedrijf (zowel bedrijfseconomisch, ruimtelijk als organisatorisch). De studie dient ook als bouwsteen voor de discussie met landbouwers en andere omgevingspartijen voor de concrete invulling van de natuurakkers. De volgende concepten staan centraal: Natuurproductiebedrijf De Molenpolder; Boeren voor natuur; Coöperatief natuurbedrijf De Graanschuu
Wat kan het buitengebied van Amsterdam betekenen voor de gezondheid van de Amsterdammers
Dit rapport gaat over de betekenis die het buitengebied van Amsterdam heeft voor de gezondheid van Amsterdammers. Van de 1349 agrariërs binnen een straal van 10 kilometer rondom Amsterdam richten er zich 7 op de zorglandbouw, 3 op educatie, 1 op kinderopvang en 49 op recreatie. Het aanbod is onvoldoende en onregelmatig verspreid. Met name op het gebied van zorglandbouw, recreatie, kinderopvang en nieuwe vormen van participatie van burgers in agrarische bedrijven is een aanzienlijke groei mogelijk. Recreatie en zorgtaken kunnen leiden tot een additioneel bedrijfsinkomen van 15.000 euro en daarmee bijdragen aan het instandhouden van landbouwbedrijven en de instandhouding van het open buitengebied
Peak incidence of distal radius fractures due to ice skating on natural ice in The Netherlands
An increase of distal radius fractures was seen in 2009 when an extended cold spell allowed natural ice skating in Amsterdam. This resulted in overload of our Emergency Departments and operating rooms. This study reports patient and fracture characteristics of these injuries. We also determined potential skating-related risk factors. All patients who sustained a distal radius fracture during natural ice skating between January 3 and January 12, 2009 were included. Patient and fracture characteristics, treatment, validated outcome (Quick DASH) at 3 months after injury were determined. Natural ice skating accounted for a 5.5-fold increase of distal radius fractures (92 fractures) compared to a similar time period without natural ice skating in 2008. Fracture types were AO-type A, n = 50, type B, n = 11 and type C, n = 31. Twenty-eight patients were casted without reduction. Fifty-four patients underwent at least one reduction before casting. The non-operative group consisted of 67 patients (68 fractures, male/female 18/49) with an average age of 55.5 years. Twenty-three patients (24 fractures) underwent internal fixation. Quick DASH for the whole group was a mean of 23.1 points (range 0–95). The mean Quick DASH for the non-operatively treated group was 19.9 points (range 0–95), for the operatively treated group 31.7 points (range 2–65). Distal radius fractures increased 5.5-fold during a period with natural ice skating. Women aged 50 and over were predominantly affected. Most fractures were extra-articular, and the vast majority was treated non-operatively. Utilization of wrist-protecting devices should be considered during future natural ice periods
Accelerated tibial fracture union in the third trimester of pregnancy: a case report
<p>Abstract</p> <p>Introduction</p> <p>We present a case of accelerated tibial fracture union in the third trimester of pregnancy. This is of particular relevance to orthopaedic surgeons, who must be made aware of the potentially accelerated healing response in pregnancy and the requirement for prompt treatment.</p> <p>Case presentation</p> <p>A 40 year old woman at 34 weeks gestational age sustained a displaced fracture of the tibial shaft. This was initially treated conservatively in plaster with view to intra-medullary nailing postpartum. Following an emergency caesarean section, the patient was able to fully weight bear without pain 4 weeks post injury, indicating clinical union. Radiographs demonstrated radiological union with good alignment and abundant callus formation. Fracture union occurred within 4 weeks, less than half the time expected for a conservatively treated tibial shaft fracture.</p> <p>Conclusion</p> <p>Long bone fractures in pregnancy require clear and precise management plans as fracture healing is potentially accelerated. Non-operative treatment is advisable provided satisfactory alignment of the fracture is achieved.</p

LCP external fixation - External application of an internal fixator: two cases and a review of the literature
The locking compression plate (LCP) is an angle-stable fixator intended for intracorporeal application. In selected cases, it can be applied externally in an extracorporeal location to function as a monolateral external fixator. We describe one patient with Schatzker V tibial plateau fracture and one patient with Gustillo IIIB open tibia shaft fracture treated initially with traditional external fixation for whom exchange fixation with externally applied LCPs was performed. The first case went on to bony union while the second case required bone grafting for delayed union. Both patients found that the LCP external fixators facilitated mobilization and were more manageable and aesthetically acceptable than traditional bar-Schanz pin fixators
Anterior-inferior plating of middle-third fractures of the clavicle
© The Author(s) 2009. This article is published with open access at Springerlink.com Introduction Various techniques have been reported for the treatment of middle-third clavicle (collar bone) fractures. This prospective study was conducted to evaluate the results of anterior-inferior plating using a 3.5-mm reconstruction plate for the treatment of middle-third clavicle fractures
Computer-assisted and patient-specific 3-D planning and evaluation of a single-cut rotational osteotomy for complex long-bone deformities
Malunion after long bone fracture results in an incorrect position of the distal bone segment. This misalignment may lead to reduced function of the limb, early osteoarthritis and chronic pain. An established treatment option is a corrective osteotomy. For complex malunions, a single-cut rotational osteotomy is sometimes preferred in cases of angular deformity in three dimensions. However, planning and performing this type of osteotomy is relatively complex. This report describes a computer-assisted method for 3-D planning and realizing a single-cut rotational osteotomy with a patient-specific cutting guide for orienting the osteotomy and an angled jig for adjusting the rotation angle. The accuracy and reproducibility of the method is evaluated experimentally using plastic bones. In addition, complex rotational deformities are simulated by a computer to investigate the relation between deformity and correction parameters. The computed relation between deformity and correction parameters enables the surgeon to judge the feasibility of a single-cut rotational osteotomy. This appears possible for deformities combining axial misalignment with sufficient axial rotation. The proposed 3-D method of preoperative planning and transfer with a patient-specific cutting guide and angled jig renders the osteotomy procedure easily applicable, accurate, reproducible, and is a good alternative for complex and expensive navigation systems
