Objective: To study and compare the functional outcome of Dynamic Hip Screw vs. Proximal Femoral Nail in basicervical fracture of femur.
Materials and Methods: A prospective randomized and comparative study of 18 months duration was conducted on 28 patients admitted in the Department of Orthopaedics in our hospital with Basicervical femur fracture. These patients were randomly treated by a Dynamic hip screw or Proximal femoral nail. The parameters studied were functional outcome in terms of Harris hip score at 4 and 12 weeks, total duration of operation, length of incision and amount of blood loss during surgery. These values were statistically evaluated and two tailed p-values were calculated and both groups were statistically compared.
Results: The average age of our patient in DHS group is 53.642±12.923 years and in PFN group is 67.285±11.424 years. The average blood loss was 115 ml and 192 ml in PFN and DHS group, respectively. The average operating time for the patients treated with PFN was 73 min as compared to 101 min in patients treated with DHS. The average HHS at 4 weeks was 53.071±12.639 and 48.428±9.120 in DHS and PFN group respectively. The average HHS at 12 weeks was 69.571±9.928 and 68.928±8.080 in DHS and PFN group respectively. Both the implants had almost similar functional outcomes.
Conclusion: In our study we have found that the PFN group has less blood loss, smaller incision and less operating time compared to DHS group. In both DHS and PFN group patients have similar HHS at 4 weeks and 12 weeks. There is no significant difference in functional outcome in terms of HHS.
