Etiologies of Hammertoes

Extensor substitution Flexor substitution Flexor stabilization

weak tibialis anterior m. causes other extensors to fire harder, which upsets the dynamics b/w other extensors (and gives one hammertoes) EDL in particular can pull toes back (swing-phase formation of hammertoes – allows toes to clear in swing but causes hammertoe formation)

Extensor substitution

weak soleus muscle causes other posterior muscles to fire stronger than normal to prevent excessive ankle dorsiflexion in midstance. Flexor substitution occurs: FDL will upset dynamic by firing stronger than normal and will cause toes to buckle proximally.

Flexor substitution

when intrinsic muscles (lumbricals or interossiae) are weak, FDL becomes a deforming force, which causes hammer toes. Over time, the contracted extensor hood becomes a “holding force” maintaining the toes in their contracted position.

Flexor stabilization

Name other factors that affect the formation of hammertoes

Hallux abducto valgus Tight shoes High heels Congenital deformity

Name other factors that affect the formation of hammertoes

Hallux abducto valgus Tight shoes High heels Congenital deformity

Ways to evaluate hammer toes

Flexible vs. Rigid Hammertoes Push-up test - push up on metatarsal base. If toes straighten, it is a flexible hammertoe. Stand on floor - same principle – toes will straighten out if flexible

Flexible vs. Rigid Hammertoes

If it is a flexible hammer toe, surgeon can do capsular and tendon work If a semi-rigid or rigid, surgeon will have to do bone work

Conservative Treatment of Hammertoes

``` Debridement of hyperkeratosis Accommodative padding around prominences Modification of foot gear Local steroid injection Oral NSAIDs Topical keratolytics Patient education Orthotic control ```

Surgical Treatment of Flexible Hammer Toes

Flexor tenotomy Extensor tenoromy Extensor hood release

Surgical Treatment of Rigid Hammer Toes

``` Arthroplasty at PIPJ PIPJ fusion Digital joint implant Middle phalangectomy Diaphysectomy Resection of base of proximal phalanx with syndactylization (joining of 2 toes surgically) ```

Surgical Treatment of Mallet Toes

Arthroplasty of DIPJ

Treatment of Heloma Molle

Exostectomy, arthroplasty, of syndactylization, since it is caused by the rubbing of head of proximal phalanx on the base of the middle phalanx of an adjacent toe

Prominence on the medial aspect of the 1st metatarsal head
