- The figurative use is virtually non-existent in English, unlike possible extended uses in Russian.
Common Mistakes

Frequently Asked Questions
No. Arthritis is inflammation of a joint, which can be a cause of ankylosis. Ankylosis is the specific end-stage result where the joint bones fuse together, eliminating movement.
True bony ankylosis is permanent and irreversible by non-surgical means. Surgical procedures like joint replacement (arthroplasty) may be used to restore mobility.
Ankylosis is a pathological, often undesirable, fusion of a joint. Arthrodesis is a surgical procedure designed to intentionally fuse a joint, usually to relieve pain from arthritis or instability.
It is pronounced ang-ki-LOH-sis, with a hard 'k' sound. Stress is on the third syllable.
