Summary

Subtalar arthrodesis with internal compression effectively treated post-traumatic arthritis, achieving high union rates. Bone grafting was not always necessary, indicating a potentially simpler surgical approach.

Area of Science:

  • Orthopedic Surgery
  • Podiatric Surgery
  • Trauma Surgery

Background:

  • Post-traumatic arthritis of the subtalar joint significantly impacts patient mobility and quality of life.
  • Surgical intervention is often necessary to manage severe cases unresponsive to conservative treatments.

Purpose of the Study:

  • To evaluate the efficacy and outcomes of subtalar arthrodesis using internal compression for post-traumatic arthritis.
  • To determine the necessity of iliac-crest bone grafting in conjunction with subtalar arthrodesis.

Main Methods:

  • Retrospective study of 24 patients (25 feet) treated between 1988 and 1992.
  • All patients underwent subtalar arthrodesis with a single compression screw; bone grafting was used selectively.
  • Follow-up averaged four years, with outcomes assessed using clinical scales and the Angus and Cowell score.

Main Results:

  • A 96% union rate was achieved across 25 treated feet.
  • Excellent or good results were reported in 17 feet based on clinical scales and 19 feet on the Angus and Cowell score.
  • Patient satisfaction was high, with 18 of 24 patients fully satisfied; no progressive arthritis was noted in adjacent joints.

Conclusions:

  • Isolated subtalar arthrodesis with internal compression is an effective treatment for post-traumatic subtalar arthritis.
  • Iliac-crest bone grafting is not routinely required for successful subtalar fusion.
  • The procedure demonstrates good long-term outcomes and patient satisfaction without promoting adjacent joint degeneration.
