Contemporary disability discourse is marked by a struggle between medical a
nd social meanings and models. The latter reflects the aspirations and yout
hful radicalism of the disability movement, while the former regards itself
as the legitimate voice of truth in all matters associated with bodily fun
ction and process. This paper argues that the battle lines between these tw
o camps need not be redrawn. Despite hints to the contrary, the proposed ex
tension of the social model to accommodate a sociology of impairment does n
ot involve a rapprochement with the medical model. On the contrary, a socio
logical account of impairment seeks to augment the armoury of the social mo
del by developing one of its weaknesses, namely the cultural critique of me
dicine. This paper examines some of the ways in which medicine has been inv
olved in the 'aesthetic invalidation' of disabled people and proposes that
'geneticization' is an important current contributor to this form of disabi
lity discrimination.
