Femoral neck fracture is most common in old age due to osteoporosis. The fracture must be reduced anatomically and fixed internally by DHS to move the patient early to avoid complication of prolonged recumbence specially bed sores. DHS allows impaction of the fracture fragments favoring union of the fracture. DHS fixation is most appropriate for basal fracture neck femur and stable transcervical fracture neck femur Garden I &II than for unstable transcervical fracture neck femur Garden III & IV.
