ICD-10-CM Code for Hallux rigidus, right foot M20. 21.
Overview. Hallux (big toe) limitus (stiffness) starts out as a stiff big toe. Over time, this develops into hallux rigidus (inability to bend), a condition where the big toe's ability to move is severely limited and may be "frozen" and unable to move at all.
'Hallux” refers to the big toe, while “rigidus” indicates that the toe is rigid and cannot move. Hallux rigidus is actually a form of degenerative arthritis. Hallux Limitus refers to the eraly forms of the arthritis and Hallux Rigidus refers to the later, more advanced stages of arthritis.
What Causes Hallux Limitus? Faulty function (biomechanics) and structural abnormalities of the foot that can lead to osteoarthritis in the big toe joint. Those with fallen arches or excessive pronation (rolling in) of the foot are susceptible to developing hallux limitus.
Unlike hallux rigidus, hallux valgus is the result of your bones shifting, with the resulting protrusion going outwards, and not upwards like with hallux rigidus's osteophyte. Hallux valgus, or a bunion, with a bump on the left big toe.
Hallux refers to the big toe, while rigidus indicates that the toe is rigid and cannot move. Hallux rigidus is actually a form of degenerative arthritis.
13.34. The second (chronic) type of hallux rigidus is much more common and occurs primarily in adults—again, in men more frequently than in women. It is frequently bilateral and is usually the result of repeated minor trauma resulting in osteoarthritic changes to the metatarsophalangeal joint of the big toe.
Grade I – mild changes with maintained joint space and minimal spurring. Grade II – moderate changes with narrowing of joint space, bony proliferation on the metatarsophalangeal head and phalanx and subchondral sclerosis or cyst.
Definition of hallux : the innermost digit (such as the big toe) of a hind or lower limb.
The term structural hallux limitus (SHL) refers to a pathology involving the lack of hallux dorsiflexion with non-weightbearing and weightbearing.
Nonsurgical management is always the first line treatment for this condition. A physician may suggest pain relievers and anti-inflammatory medicines, ice or heat packs, or even injections into the joint to reduce pain and stiffness.
Hallux rigidus is often accompanied by a bunion on the top of the foot, making shoes uncomfortable to wear. As the condition worsens, patients may experience aching or pain in the knee, hip of lower back. Hallux rigidus is diagnosed through the taking of a medical history, physical examination and X-rays.
