2. True impactions of fractures of the femoral neck occur rather infrequently.
3. Improper reductions, and interposition of the hip joint capsule, are the principal causes of non-union.
4. The surgical treatment of ununited fractures of the femoral neck should preserve if possible the anatomic structures.
