Description
Aim: To assess the results of internal fixation of fracture neck femur in the sixth and seventh decades of life by dynamic hip screw (DHS) and antirotation screw. Material & Method: 46 patients with displaced fracture neck femur were treated in Department of Orthopedics, Vardhman Institute of Medical Science, Pawapuri, Nalanda, Bihar, India for 12 months by closed reduction and internal fixation by DHS and antirotation screw. Results: The time elapsed between trauma and surgery ranged from few hours to 7 days with an average of 3 days. Bone union was achieved in all patients except five. The time to bone union ranged from 3 to 7 month with an average of 6 months. The time to full weight bearing ranged from 3 to 7 months with an average of 5 months. The reduction in the horizontal offsets ranged from 2 mm to 6 mm with an average of 3 mm. This reduction in neck length and horizontal offset was found statistically to be significant (p value < 0.05). Conclusion: Internal fixation of fracture neck femur in the sixth and early seventh decades of life by DHS and antirotation screw has the advantages of short operative time and early weight bearing with high union rate. It is a hip preserving surgery and if non union or avascular necrosis had occurred, hip arthroplasty could be done without major difficulties. Patients above the age of 65 years and patients with Garden type IV fractures carry the risk of poor results.

Results: The time elapsed between trauma and surgery ranged from few hours to 7 days with an average of 3 days. Bone union was achieved in all patients except five. The time to bone union ranged from 3 to 7 month with an average of 6 months. The time to full weight bearing ranged from 3 to 7 months with an average of 5 months.
