Dynamic hip screw fixation results in a significantly higher proportion of satisfactory outcomes compared to cannulated screws in patients with fresh femoral neck fractures.
Supports dynamic hip screw as preferred fixation for femoral neck fractures; extends RCT evidence on short-term functional outcomes.
Objectives: To compare the outcome of DHS (dynamic hip screw) vs cannulated screws in managing fracture of neck of femur. Study Design: Randomized controlled trial. Study Duration: 22-06-2021 to 21-12-2021 (6 months) Settings: Department of Orthopedic, D.G Khan Hospital, D.G Khan. Materials & Methods: A total of 60 patients with fresh fracture neck of femur, 18 to 60 years of age of both genders were included. The DCS group was managed by internal fixation with Dynamic hip screw and CS group was treated by internal fixation with cannulated screws. All patients were followed for 3 months for outcome. Results: Total 60 patients of fracture of femur neck was recruited. Mean age and mean duration of fracture was 44.42 ± 12.45 years and 10.67 ± 5.66 days. In DCS group, mean age and duration of fracture was 44.57 ±11.60 years and 10.23 ± 5.86 days respectively. In CS group, mean age and mean duration of fracture was 44.27 ± 13.46 years and 11.10 ± 5.51 days respectively. In DCS group, satisfactory outcome was found in 25 (83.33%) patients while in CS group, it was found in 13 (43.33%) patients. After applying chi-square test, it was noted that DCS group had significantly (P=0.003) higher proportion of satisfactory outcome as compared to CS group. Conclusion: Results of this study showed that DCS group had significantly higher proportion of satisfactory outcome as compared to CS group in cases of femur neck fractures. Most of the patients were between 41-60 years of age but difference of satisfactory outcome between DHS group and CS group was not significant. Regarding male patients, significantly higher rate of satisfactory outcome was noted in DHS group as compared to CS group.

Ullah et al. (2022) conducted an RCT in Femoral neck fracture (n=60). Dynamic Hip Screw (DHS) vs. Cannulated Screws (CS) was evaluated on Satisfactory outcome (Modified Merle d’Aubigne score) (p=0.003). Dynamic hip screw fixation resulted in a significantly higher proportion of satisfactory outcomes at 3 months compared to cannulated screws (83.33% vs 43.33%, p=0.003) for femoral neck fractures.
