Summary
Arthroscopic double and triple hindfoot fusions are feasible salvage procedures for pain and deformity. This technique allows for joint decortication and deformity correction while preserving soft tissues, though adjacent joint issues may arise later.
Area of Science:
- Orthopedic Surgery
- Minimally Invasive Procedures
- Foot and Ankle Reconstruction
Background:
- Arthroscopic arthrodesis is established for ankle but less common for multiple hindfoot joints.
- This study evaluates the feasibility of arthroscopic fusion for multiple hindfoot joints.
Purpose of the Study:
- To assess the feasibility, outcomes, and complications of arthroscopic arthrodesis involving two or three hindfoot joints.
Main Methods:
- A review of 18 consecutive arthroscopic hindfoot fusions (double or triple joint) from a series of 112 procedures.
- Evaluation focused on union rates, complications, and functional improvement compared to preoperative status.
Main Results:
- No perioperative complications were observed.
- Four patients undergoing triple fusions achieved good or excellent outcomes.
- Three out of 14 patients with combined subtalar and talonavicular fusions experienced talonavicular non-union.
Conclusions:
- Arthroscopic double and triple hindfoot arthrodeses are viable salvage options for managing pain and deformity.
- The technique enables decortication and correction of deformity while maintaining soft tissue integrity.
- Potential for late-onset adjacent joint pain and arthrosis exists.
