Summary

For elderly hip fractures, both Ender nailing and dynamic hip screw (DHS) allow prompt walking. However, DHS shows a lower complication rate than Ender nailing, reducing reoperation needs.

Area of Science:

  • Orthopedic surgery
  • Trauma care
  • Geriatric medicine

Background:

  • Proximal femur fractures are common in the elderly.
  • Surgical fixation is standard treatment.
  • Ender nailing and dynamic hip screw (DHS) are common procedures.

Purpose of the Study:

  • To compare operative strain and postoperative outcomes of Ender nailing versus DHS in elderly patients with proximal femur fractures.
  • To evaluate complication rates and reoperation necessity for both procedures.

Main Methods:

  • Retrospective analysis of 51 patients treated with Ender nailing and 45 patients treated with DHS between 1985 and 1987.
  • Assessment of operative time, trauma, and postoperative mobility.
  • Documentation of technical complications and reoperation rates.

Main Results:

  • Both Ender nailing and DHS facilitated prompt ambulation and full weight-bearing.
  • Both methods demonstrated minimal operative strain and trauma.
  • Ender nailing was associated with higher rates of specific technical complications, including nail migration and external rotation malpositioning.
  • A higher rate of reoperations was observed in the Ender nailing group.

Conclusions:

  • Dynamic hip screw (DHS) fixation may offer a lower complication rate compared to Ender nailing for proximal femur fractures in the elderly.
  • DHS application can potentially reduce the need for reoperations in this patient population.
