Dislocation of hip

Nine out of ten hip dislocations are posterior. The affected limb will be shortened and internally rotated in this case.

In an anterior dislocation the limb will not be lengthened as noticeably and will be externally rotated.

Congenital hip dislocation must be detected early when it can be easily treated by a few weeks of traction. If it is not detected the child’s hip may develop incorrectly seen when the child begins to walk. If one hip is affected the child will be have a limp and lurch and with bilateral dislocation there will be a waddling gait.

Acquired hip dislocations can be extremely painful and commonly occur during car accidents. They may be treated by surgical realignment and traction.
