[Tibiocalcaneal arthrodesis using retrograde insertion of a compression nail]

Area of Science:

• Orthopedic Surgery
• Traumatology
• Reconstructive Surgery

Background:

• Ankle arthrodesis is a surgical procedure to fuse the upper and lower ankle joints.
• Indications include malunion, nonunion, failed previous fusions, and severe osteoarthritis.
• Achieving stable fixation for early mobilization is a key surgical goal.

Purpose of the Study:

• To evaluate the efficacy of retrograde compression nailing for ankle arthrodesis.
• To assess the rate of osseous consolidation and functional recovery.
• To determine the complication rate associated with this technique.

Main Methods:

• Retrospective analysis of 12 patients undergoing ankle arthrodesis with retrograde compression nailing.
• Surgical technique involved transfibular approach for joint preparation and retrograde nail insertion.
• Postoperative management included casting and progressive weight-bearing protocols.

Main Results:

• All 12 patients achieved osseous consolidation at 16 weeks postoperatively.
• Ten patients experienced pain-free full weight-bearing by 12 weeks.
• Three complications were reported: varus malalignment, refracture, and screw loosening.

Conclusions:

• Retrograde compression nailing is an effective method for ankle arthrodesis, promoting stable fixation and union.
• The technique facilitates early weight-bearing and pain relief for a majority of patients.
• While generally safe, potential complications should be considered during patient selection and management.
