Abstract
1 . Dislocation of the upper end of the fibula is probably less unusual than the paucity of the published reports suggests.
2. Dislocation may be anterior or posterior, anterior dislocation occurring about twice as often as posterior. Rarely the fibula moves proximally.
3. In most cases a closed manipulation suffices for reduction, and a full and rapid return of normal function follows.
4. Five cases are described. In one case operative reduction was required.
