Medical devices for the treatment of spinal conditions are described herein. The medical device includes a main body that is adapted to be placed between the L5 vertebra and the sacrum so that the main body acts as a spacer with respect to the L5 vertebra and the sacrum to maintain distraction therebetween when the spine moves in extension. Channels are formed in the lower portion of the main body and allow a fixation device to extend through each channel at different angles. A locking mechanism is disposed in the channels to lock the fixation devices in each channel with respect to the device in a desired orientation.
