Tarsal Coalition Surgery: Duration and What to Expect

Tarsal coalition resection (or arthrodesis for advanced cases) typically takes 2–3 hours under general or regional anesthesia. Duration varies by:

• Coalition type (calcaneonavicular, talocalcaneal) and location
• Surgical approach (open vs. arthroscopic-assisted)
• Whether concomitant procedures are needed (osteotomy, tendon transfer)
• Patient anatomy and scar tissue from prior surgery

Typical Course

• Incision over coalition site; resection of bony/cartilaginous bridge.
• Interposition (fat graft, wax, muscle) to prevent recurrence.
• If arthrodesis: joint preparation, fixation (screws/plate), bone graft.

Post-Op

• Non-weight-bearing cast/boot 4–6 weeks (resection); 6–12 weeks (fusion).
• Progressive PT for ROM, strength, proprioception.
• Full recovery: 3–6 months (resection); 6–12 months (fusion).

Outcomes are generally good for resection in adolescents; fusion provides durable pain relief for advanced arthritis.
