Subtalar arthrosis surgery using Silastic wedges can cause complications. CT scans effectively identify implant issues like malposition and loosening, guiding revision surgery for persistent pain in flatfoot deformities.

Area of Science:

  • Orthopedic Surgery
  • Radiology
  • Biomedical Engineering

Background:

  • Subtalar arthrosis surgery aims to correct osseous malalignment in flatfoot deformities.
  • Silastic wedges are implanted into the lateral subtalar joint to achieve this correction.
  • Persistent pain after surgery necessitates evaluation of implant integrity and position.

Purpose of the Study:

  • To evaluate the utility of computed tomography (CT) in assessing subtalar implants after surgery for flatfoot deformity.
  • To identify common causes of persistent pain related to subtalar implants using CT imaging.

Main Methods:

  • Retrospective review of CT scans from 13 patients (seven patients) with subtalar implants over 3.5 years.
  • Analysis of implant position, orientation, and surrounding tissues in both asymptomatic and symptomatic cases.

  • Correlation of CT findings with patient symptoms and outcomes of revision surgery.

    • Main Results:

    • CT scans of four asymptomatic implants showed normal position and orientation.
    • CT scans of nine painful implants revealed abnormalities including oblique orientation (44%), loosening (33%), methyl methacrylate extrusion (22%), and abnormal calcaneal recession (22%).
    • Five of nine painful implants underwent revision surgery with symptom improvement.

    Conclusions:

    • CT scanning is a valuable tool for assessing subtalar implant position and orientation.
    • CT can identify specific complications such as malposition, loosening, and extrusion contributing to persistent pain.
    • Revision surgery based on CT findings can effectively manage pain after subtalar arthrosis procedures.
