Resection of talocalcaneal tarsal coalitions can yield good results, especially when coalitions involve less than one-third of the joint surface. Age is not a barrier, but varus deformity may indicate a poorer prognosis.

Area of Science:

  • Orthopedic Surgery
  • Foot and Ankle Surgery
  • Podiatric Medicine

Background:

  • Talocalcaneal tarsal coalition causes persistent foot pain and functional limitation.
  • Surgical resection is a treatment option for symptomatic talocalcaneal tarsal coalition.
  • Understanding outcomes based on coalition size and associated deformities is crucial.

Purpose of the Study:

  • To evaluate the clinical outcomes of talocalcaneal tarsal coalition resection.
  • To assess the impact of coalition size and varus deformity on surgical success.

Main Methods:

  • Retrospective review of 20 patients undergoing talocalcaneal tarsal coalition resection over 10 years.
  • Clinical outcomes assessed at an average 29-month follow-up.
  • Preoperative computed tomography (CT) scans used to evaluate coalition size in 17 patients.

Main Results:

  • 77% of patients achieved good or excellent results when coalitions involved one-third or less of the joint surface.
  • Increasing patient age did not contraindicate surgery.
  • Four patients with uncommon varus deformity had a poorer prognosis following resection.

Conclusions:

  • Resection of talocalcaneal tarsal coalition is effective, particularly for smaller coalitions.
  • Coalition size is a significant factor in predicting surgical success.
  • Varus deformity may be associated with less favorable outcomes after coalition resection.
