CONGENITAL DISLOCATION OF THE HIP: Report of an Unusual Case.

RIDLON, JOHN
The Journal of Bone & Joint Surgery: July 1928
Case Report

1. There are some cases of congenital dislocation of the hip that are really congenital dislocations,-not merely shallow sockets and deformed heads and necks that are easily dislocated.

2. Dislocated hips gradually travel upward, little or much depending upon whether they are far forward or far backward. Those that are forward go up little more than the transverse diameter of the heads. Those at the back may go up as much as four and one-half inches.

3. False sockets, more or less deep, develop with a more or less secure rim, in this instance to the height of half an inch, sufficient to retain the dislocated head in its new position.

4. The range of motion gradually increases with use.

5. When considering Alexander Hugh Ferguson's operation of turning down a shelf from the outer table of the ilium, it may be well to wait long enough to determine if the operation is really necessary.

6. In considering the advisability of doing an operation to correct an assumed twist in the femoral neck, the length of the neck should first be determined. This is also a matter when considering the probability of the replaced head being retained in the acetabulum after it has been put there.
