Abstract: An angular adjustment mechanism for a surgical instrument is described. The mechanism comprises an adjustment member (102) configured for rotation about a longitudinal axis (122), the adjustment member comprising a plurality of pairs of facets (134) arranged about the longitudinal axis. Each of the plurality of pairs of facets defines a respective angled axis (148B,148C) at an angle (150B,150C) relative to the longitudinal axis. A pivoting member (104) is arranged to pivot about a pivot axis perpendicular to the longitudinal axis and comprises a recess (128) for receiving the adjustment member and engaging one pair of the plurality of pairs of facets. This provides an angular adjustment mechanism in which facets on the outside of the adjustment member engage corresponding surfaces in a recess on a pivoting member. The use of facets provides a secure connection while allowing a greater degree of angular adjustment and providing a further benefit of simple operation.

Abstract: A surgical cutting guide (8) is described which comprises a body section delimiting a recess (14) extending into the body section from an external surface. The recess has a central axis and is for receiving an attachment protrusion (18) from a surgical alignment guide (6). The recess comprises: a first portion (36) having a first constant cross section along the central axis; and a second portion (38) having a second constant cross section along the central axis which is larger than the first constant cross section. The first and second portions are coaxial with the central axis and the second portion is closer to the external surface than the first portion. This configuration creates a stepped surface in the recess which is engaged by corresponding features on a protrusion of a surgical alignment guide.

Abstract: Provided in embodiments of the present invention is a method of wagering on a plurality of events. In one embodiment, the method includes accepting a plurality of participants to wager on the events and providing each participant with a fantasy bankroll of money to wager on the events. After the participants have been provided with their respective fantasy bankrolls, wagers from the participants on a first event are received. After the event has been completed, a finishing order of the participants is determined. Next, a portion of the participants is cut based on the finishing order to form a group of finalists. The finalist wager on a second event and a finishing order of the finalists is determined from the outcome of the second event. Prizes are then awarded based on the finishing order of the finalists.

Abstract: A surgical instrument system is described which comprises an alignment guide (6,100) comprising a body section having a through bore (50) defining a longitudinal axis (122); and a rod (40) comprising a cylindrical member (2) for insertion into the through bore; and a restraining system (46, 52, 48, 94) for preventing relative movement of the alignment guide and rod along the longitudinal axis, when the cylindrical member is inserted into the through bore, and the alignment guide is located towards the proximal end of the rod. The restraining system may comprise a resilient element (46) and a recess (52) configured to engage the resilient element. In a preferred embodiment, a resilient member is disposed on the surface of the rod. Such a system allows the alignment guide to be restrained towards the proximal end of the rod so that the rod can be inserted to a patient using one hand, rather than requiring two hands (one to secure the alignment guide relative to the rod and one to insert the rod).

Abstract: An instrument for positioning a cup component of an orthopaedic joint prosthesis includes a shaft, a housing attached to the distal end of the shaft, at least two flange portions carried on the shaft on which the cup component can be fixed, and a unitary spring element disposed about the shaft axis and disposed between the at least two flange portions and the axis of the shaft. The housing includes a base plate and extends from the shaft transversely relative to the shaft axis. The at least two flange portions can move relative to the base plate in a direction transverse to the shaft axis between an in-use position, where at least a portion of each of the at least two flange portions contacts the inner surface of the cup component, and a retracted position where the at least a portion of each of the at least two flange portions is moved towards the shaft axis so as to allow the cup component to be released from the instrument.

Abstract: An instrument for positioning a cup component of an orthopaedic joint prosthesis includes a shaft, and a flange located near an end of the shaft on which the cup component can be fixed. The flange extends from the shaft transversely, and can be retracted from an in-use position wherein the flange is received in a groove in the internal surface of the cup component when positioned over the said end of the instrument, and a retracted position in which the flange is withdrawn toward the axis of the shaft from the in-use position, allowing the cup component to be released from the instrument.

Abstract: A surgical jig defines an axis relative to a body part and includes a support, a first guide element mounted on the support and a second guide element mounted on the support. Each guide element includes a guide channel and the guide channels between them define a substantially linear jig axis.

Abstract: In some embodiments, a container is provided with a frame including one or more support structures each having a stacking post with a thin cross-sectional shape. Multiple support structures having such stacking posts can be provided along the length of the container to enable the container to be used in a stacked configuration. The container can provide an expanded interior loadable width for increased loading flexibility and capacity, and can have recessed upper and lower handling fitting joints in order to provide stronger and space-saving connections between a header and an upper handling fitting, between the upper handling fitting and a stacking post, between the stacking post and a lower handling fitting, and/or between the lower handling fitting and a floor component.
