Does anyone know the cause of a lateral drift of the 3rd phalange from the 2nd on both feet? Plantarflexed metatarsal head and no signs of plantar plate tear. Possibly hereditary.

I see it in Plantar Plate Tear patients and Morton Neuroma Patients always thought it was something to do with nerve function being affected in those patients.

 

This maybe of interest

- SECOND METATARSOPHALANGEAL JOINT INSTABILITY

 

This is called Sullivans sign.

Indicates plantar plate tear on the opposite side of the relevant joint to the direction of subluxation.
