An apparatus for performing fracture reduction comprises (i) a first manipulator 200 in the form of a limb support (202, Fig 2) which is configured for removable attachment to the limb, such that distraction of the bone section can be performed without any attachment of another manipulator to the bone section, and/or (ii) a second manipulator 400 for manipulating a first bone fragment of the fracture, wherein the second manipulator is mounted on a moveable platform 300 having multiple degrees of freedom and is configured to manipulate the first bone fragment by means of a percutaneous attachment device (502, Fig 9) attached to the first bone fragment. An imaging system for use in fracture reduction surgery is also contemplated； comprising of (i) an optical tracking tool (600, Fig 6) configured for attachment to a percutaneous attachment, (ii) an optical tracking device (504, Fig 6) configured to track the position and orientation of the optical tracking tool and (iii) a processing system (506, Fig 6) for updating a model of the fracture based on data received from the optical tracking device.
