It is important to make a foot- print on the condyle by drilling only half of the head of the drill bit into the bone purchase alendronate 35mg overnight delivery. The drill bit is retracted and the footprint examined to deter- mine if it is in the correct position (Fig. Tunnel Dilation Tunnel dilation is a method to compact the tunnel wall to improve the pullout strength of the interference screw. In the middle-aged patient, the tunnels should be dilated 2 sizes to improve the ﬁxation strength. For example, if the graft is 8mm, drill a 6-mm tunnel and dilate 2 sizes. Drilling a small tunnel in both the tibia and femur and inserting the graft passing wire through both tunnels facilitates the dilation procedure. With the graft passing wire inserted, both tunnels can be quickly dilated with a single pass of the dilators (Fig. Tunnel Notching The edge of the tunnel must be notched to start the BioScrew (Linvatec, Largo, FL) (Fig. The Notcher (Linvatec, Largo, FL) is inserted through the tibial tunnel to notch the femoral tunnel. This demonstrates the notch in the edge of the tunnel to start the screw. Graft Passage 111 Graft Passage The four-bundle semi-t and gracilis graft is attached to the looped end of the graft passing guide wire and the number 5 Ti-Cron is drawn into the femoral tunnel. The knee is hyperﬂexed, and the BioScrew guide wire is introduced through the low anteromedial portal and into the notch in the femoral tunnel. The guide wire should lie on top of the graft, not pushed into the graft. The wire is shoehorned on top of the graft as it is pulled into the tunnel. The graft is drawn up to the edge of the femoral tunnel, and the ﬂexible BioScrew guide wire is laid on top of the graft at the notched region of the tunnel (Fig.
In expanding to fill the moral vaccuum resulting from the decline of the churches and the increasing fragmentation of society alendronate 70 mg on-line, medicine has come to play a much wider social role. It has displayed considerable flexibility in incorporating both traditional concerns about the decline of family values and fashionable commitments to pluralism and diversity, particularly in the sphere of sexuality. The philosopher David Mechanic has observed how medicine ‘can be, at the same time, remarkably tolerant and extraordinarily judgemental’, now accepting, for example, masturbation and homosexuality, after a long history of pathologising these activities, but fiercely condemning any departure from the safe sex code (Mechanic 1997). As Mechanic continues, there are such large areas of uncertainty today that ‘moral entrepreneurs have endless opportunities to ply their trade’. Nowhere are these opportunities so great as they are in the sphere of health promotion. It is important, however, not to exaggerate the potential of health to take over the role of religion. The parallels between Moses’ Ten Commandments and Liam Donaldson’s Ten Tips for Better Health are striking—they are even more explicit in the ‘European Code Against Cancer, or Ten Commandments’ cited in the Health of the 70 SCREENING Nation White Paper (DoH December 1999: xiv; DoH 1992:66). Injunc-tions against certain activities—‘thou shalt not’—are a feature of both codes, but figure even more prominently in the morality of health promotion. Whereas the Mosaic code emphasised the conduct of individuals in society, the healthy lifestyle command-ments have a highly individualistic focus. As many commentators have noted, this narcissistic character of the contemporary cult of health reflects the anxieties of an increasingly atomised society. The fact, for example, that health promotion initiatives tend to be taken up more readily by the better off in society means that the advance of this agenda is likely to intensify social fragmentation rather than help to overcome it. Perhaps the greatest defect of health promotion, by contrast with traditional religion, is its lack of an inspirational element. Another version of the ten commmandments of health promotion—the American Institute of Public Medicine’s ‘Ten New Year Resolutions’ for 1992—included alongside the familiar exhortations, recommendations to ‘develop a social support network’ and to ‘have a sense of purpose’ (quoted in Rosenberg 1997). If only tackling these great social and spiritual deficits of the late twentieth century Western world were as easy as other ‘resolutions’, such as ‘avoiding second hand smoke’ and ‘limiting red meat, eggs and cheese’. Futhermore, when it comes to suffering and death, the inescapable elements of the human condition, the health promotionists fall silent.
