Abstract: A retractor assembly suitable for hip or other joint surgery comprising a structural member (1), which consists of a handle (2) that extends proximal through a curved region (4) to a distal region (3) adapted for use in a suitable patient, a light ducting member (5), which is at least in part in substantial conformity to the curved region (4), adapted in use to receive light and reliant on internal reflection of the light, to transmit such received light about at least part of the curved region to an emission outlet (7) which casts light to a zone at and/or about said distal region (3), and a shield (6) overlying at least that part of the light ducting means (5) in substantial conformity to at least part of the curved region (4), wherein the light ducting member (5), the shield (6) and the structural member (1) can be brought into assembly so that directly and/or indirectly each of the light ducting member (5) and the shield (6) is in a supported condition relative to the structural member (1).
