Foot Surgery: Flexible and Rigid Hammertoes
With hammertoes, one or more toes curl or bend abnormally. This can be caused by an inherited muscle problem, an abnormal bone length, or poor foot mechanics. The affected joints can rub inside shoes, causing corns (buildups of dead skin).
Flexible Hammertoes
When hammertoes are flexible, you can straighten the buckled joints. Flexible hammertoes may become rigid over time.
Tendon Release
This treatment helps release the buckled joint. The bottom (flexor) tendon may be repositioned to the top of the affected toe (flexor tendon transfer). Sometimes, the top or bottom tendon is released but not repositioned (tenotomy). Right after surgery, you can bear weight on your foot.
Rigid Hammertoes
Rigid hammertoes are fixed (not flexible). You cannot straighten the buckled joints. Corns, pain, and loss of function may be more severe with rigid hammertoes than with flexible ones.
Arthroplasty
A part of the joint is removed, and the toe is straightened. In some cases, the entire joint may be replaced with an implant. You can bear weight on your foot right after surgery. When healed, the bones become connected with scar tissue, making your toe flexible.
Fusion
First, the cartilage and some bone on both sides of the joint are removed. Then, the toe is straightened, and the two bones are held together, often with a pin. The pin is removed after several weeks. You can bear weight on your foot right away. Once your foot heals, the toe will be less flexible, but more stable.
