TORONTO HALLUX LIMITUS/RIGIDUS
posted: Apr. 06, 2014.
Hallux Limitus/Rigidus
Hallux Limitus is a term used to describe a first metatarsophalangeal joint (MTPJ) that has developed a painful limitation in motion secondary to an acquired arthritic condition. This limitation in motion is progressive and may lead to a condition termed Hallux Rigidus, in which there is an absence of motion. During normal gait the first MTPJ dorsiflexes 50-75 degrees, and requires stability of proximal bones and joints to function properly. Abnormalities such as pronation, trauma, neuromuscular disease, arthritic conditions, or variations in bone structure can interfere with normal first MTPJ function and lead to a decrease in motion.
Appearance
Outwardly the condition may look like a bump on the top of the first metatarsal head with varying degree of limitation of the first MTPJ motion.
Symptoms

Diagnosis
Physical examination and biomechanical assessment: The limitation in motion may not be appreciated in a non-weighbearing patient, proper loading of the first ray may reveal a functional limitation in motion. The patient may complain of pain beneath the second metatarsal or even the lateral aspect of the foot due to transfer of pressure from the first MTPJ as it's function declines.
X-rays will be used to help determine the severity of the condition, structural or positional deformity, as well as the proper course of treatment.
Ultrasound may also be used to evaluate the dynamic functioning of the first MTPJ.
Conservative Treatment
Initial treatment involves management of symptoms and biomechanical control.
- Changes in shoe gear
- Functional orthotics: Orthotics are and important part of treatment, especially when biomechanical abnormalities are present
