What are digital deformities
Digital deformities are changes in the normal alignment of the toe. They are named after the joints that are affected.
A Clawed Toe involves dorsiflexion of the proximal phalanx on the lesser metatarsophalangeal (MTP) joint and flexion of the proximal interphalangeal (PIP) and distal interphalangeal (DIP)
A Mallet Toe does not involve any deformity of the proximal phalanx on the lesser metatarsophalangeal (MTP) joint or proximal interphalangeal (PIP) joint. Typically, the only joint affected is the distal interphalangeal (DIP) joint which is flexed.
A Hammer Toe sometimes involves dorsiflexion of the proximal phalanx on the lesser metatarsophalangeal (MTP) joint and flexion of the proximal interphalangeal (PIP). Typically, the DIP joint is extended or neutral in a hammer toe.
Causes of digital deformities
Biomechanical abnormalities
Small intrinsic muscles in the foot usually maintain the the toe in a straight position
When the long extrinsic muscles that work harder than the small intrinsic muscles the toe starts to claw.

Complications of digital deformities
- Corns and callous
- Toenail pain
- Ulcers and wounds
Treatment of digital deformities
- Silicon padding and sleeves
- Taping
- Shoe stretching and modification
- Surgical release and re positioning of the digit
- Percutaneous tenotomy is a permanent way to fix the alignment of the toe click for more information Flexor Tenotomy
