Surgical Treatment Options

If conservative treatments fail to provide relief, surgical intervention may be considered. The specific procedure will depend on the severity of the hammer toe and the individual patient's needs.

1. Tendon Release

• This procedure involves cutting the tendon that is causing the toe to bend, allowing it to straighten.

2. Osteotomy

• In this procedure, a portion of the bone in the toe is removed or reshaped to correct the alignment. This is often done in conjunction with tendon release.

3. Fusion

• In severe cases, the affected joint may be fused to prevent movement and alleviate pain. This is typically considered when other treatments have not been successful.

4. Exostectomy

• This involves the removal of bony growths or deformities that may be contributing to the hammer toe condition.

Conclusion

The treatment of hammer toes, particularly those classified under ICD-10 code M20.40, typically begins with conservative measures aimed at alleviating symptoms and improving foot function.
