20090222010 | Instrument for use in a joint replacement procedure - An instrument for locating the cutting plane on the head of a long bone in a surgical procedure, wherein the head of the bone is replaced with a joint prosthesis component, includes an axial reference shaft which can be arranged parallel to the axis of the bone and a cutting guide which can be moved relative to the axial reference shaft. The cutting guide has a reference block for location against the bone relative to the edge of the bone at one side and at least one arm which is shaped so that it can extend from the cutting guide over the face of the head. The arm can be located positively with respect to features on the head so that the location of the reference block along the axis of the bone can be set with reference to features on the head of the bone which are contacted by means of the arm. | 09-03-2009 |
20090270864 | CUTTING GUIDE ASSEMBLY - A cutting guide assembly is provided for resecting a head of a bone. The cutting guide assembly includes an elongate support rod and at least one cutting plate couplable to the support rod, the at least one cutting surface defining a cutting surface arranged such that when coupled to the support rod, the bone can be cut to form a resection surface by aligning a cutting tool with the cutting surface. The support rod is configured to be partially disposed in and rotatable within a cavity extending into the head of the bone, defines a longitudinal axis and including a reference formation. | 10-29-2009 |
20090270865 | REAMING GUIDE ALIGNMENT INSTRUMENT - An alignment system for aligning a reaming guide during insertion into a cavity of a bone is provided. The bone has a resected surface and the cavity defines a cavity axis. The system includes a reaming guide that includes an elongate stem portion having a stem axis, a neck portion extending from the stem portion at an incline with respect to the stem axis, and an alignment instrument. The alignment instrument includes a handle defining a handle axis, the handle being releasably couplable to the reaming guide such that the handle axis is in a predetermined relationship with the stem axis. The alignment instrument further comprises a plane finder slidably coupled to the handle, the plane finder comprising a surface defined by a plane that intersects the axis of the handle at an angle having a predetermined relationship with the angle at which a resection surface of the bone intersects the cavity axis. | 10-29-2009 |
20090270866 | VARIABLE OFFSET REAMER ASSEMBLY FOR MODULAR HUMERAL COMPONENT - An instrument kit for reaming a cavity within a resected head of a bone is provided. The kit includes a reaming guide, at least two adaptor sleeves and a reamer. The reaming guide includes an elongate stem portion insertable into a cavity extending into the bone from a resection surface at the head of the bone and a neck portion. The at least two adapter sleeves are mountable upon the reaming guide. Each adapter sleeve has a longitudinal axis, being generally cylindrical and a bore configured to receive part of the neck portion of the reaming guide. When the adapter sleeve is mounted upon the neck portion of a reaming guide inserted into a cavity in a bone the reamer is arranged to ream a cavity into the resection surface of the bone around the neck portion. | 10-29-2009 |
20090270867 | REAMER GUIDE FOR REVISION PROCEDURE - An instrument kit is provided for reaming bone around a head of a bone, the bone including an implanted epiphysis component. The instrument kit includes a reaming guide and a reamer. The reaming guide is couplable to the epiphysis component and has a first reamer support feature and a second reamer support feature. The reamer is couplable to one of the first reamer support feature and the second support feature to ream bone around the epiphysis component. | 10-29-2009 |
20090270875 | MEASURING INSTRUMENT FOR VERSION ANGLE - An instrument for measuring an angle about a cavity axis defined by a cavity extending into a head of a bone is provided, the bone having been resected on a plane that is inclined relative to the cavity axis. The instrument includes a stem arranged to be inserted into the cavity, a plane finder and a scale. The plane finder is coupled to the stem and arranged to contact the resection surface as the stem is inserted into the cavity and to move relative to the stem until the plane finder lies in a plane parallel to the resection surface. Movement of the plane finder relative to the stem is indicative of the angle about the cavity axis between a radial position indicated by part of the stem and a line extending perpendicularly from the resection surface. The scale is configured such that movement of the plane finder relative to the stem is indicated by the position of a portion of the plane finder relative to the scale. | 10-29-2009 |
