the final management depends on the size of the fragment(s), stability and congruence of the joint. in some cases traction for six to eight weeks may be the only treatment required; however, surgical fixation using screw(s) and plate(s) may be required if the injury is more complex. the latter treatment will be called for if bone fragments do not fall into place, or if they are found in the joint, or if the joint itself is unstable.
