Overview

Randomized trial compares intraoperative Steinmann pin technique to preoperative digital planning in total hip arthroplasty, suggesting improved leg length control.

Key Points

  • To evaluate the effectiveness of Steinmann pin measurement versus preoperative digital planning in total hip arthroplasty.
  • Prospective randomized control study comparing two techniques for measuring leg length during total hip arthroplasty.
  • Group A used Steinmann pin for intraoperative measurement, while group B relied on preoperative digital planning with software.
  • Assessment of postoperative leg length discrepancy, operative time, and blood loss.
  • Steinmann pin group (group A) showed significantly lower postoperative leg length discrepancy (p < 0.05) compared to the preoperative planning group (group B).
  • No significant differences in operative time or blood loss between the two groups were observed.
