A device for treating bone fractures, preferably for the treatment of acetabular fractures, comprising: a clamping mechanism including a clamp defining a cable receiving channel extending therethrough and a compression member coupled to the clamp for movement relative thereto, wherein movement of the compression member relative to the clamp in a first direction moves the clamping mechanism into a clamping configuration in which at least a portion of the clamp is compressed into the channel to fix a cable received therein relative to the clamping mechanism, characterized in that the device further comprises an actuating mechanism removably coupleable to the clamping mechanism, the actuating mechanism including: a first member removably engagable with the clamping mechanism so that, when engaged, the first member prevents relative movement between the clamp and the first member; and a second member removably engagable with the clamping mechanism and movably coupled to the first member so that, when engaged, the second member prevents relative movement between the compression member and the second member, relative movement between the first and second members (32;30) causing relative movement between the clamp and the compression member to move the clamping member between the clamping configuration and a release configuration in which the cable is permitted to move through the clamping mechanism; and a tensioning mechanism for drawing the cable through the clamping mechanism and applying a desired degree of tension thereto. a clamping mechanism including a clamp defining a cable receiving channel extending therethrough and a compression member coupled to the clamp for movement relative thereto, wherein movement of the compression member relative to the clamp in a first direction moves the clamping mechanism into a clamping configuration in which at least a portion of the clamp is compressed into the channel to fix a cable received therein relative to the clamping mechanism, characterized in that the device further comprises an actuating mechanism removably coupleable to the clamping mechanism, the actuating mechanism including: a first member removably engagable with the clamping mechanism so that, when engaged, the first member prevents relative movement between the clamp and the first member; and a second member removably engagable with the clamping mechanism and movably coupled to the first member so that, when engaged, the second member prevents relative movement between the compression member and the second member, relative movement between the first and second members (32;30) causing relative movement between the clamp and the compression member to move the clamping member between the clamping configuration and a release configuration in which the cable is permitted to move through the clamping mechanism; and a first member removably engagable with the clamping mechanism so that, when engaged, the first member prevents relative movement between the clamp and the first member; and a second member removably engagable with the clamping mechanism and movably coupled to the first member so that, when engaged, the second member prevents relative movement between the compression member and the second member, relative movement between the first and second members (32;30) causing relative movement between the clamp and the compression member to move the clamping member between the clamping configuration and a release configuration in which the cable is permitted to move through the clamping mechanism; and a tensioning mechanism for drawing the cable through the clamping mechanism and applying a desired degree of tension thereto.
