Answer :
Final answer:
Boutonnière deformity, common in Rheumatoid Arthritis (RA), is often tied to MCP, PIP, and DIP joint pathology and results from the dorsal subluxation of the lateral cords. It can be corrected with a fusion of the DIP joint or a tenotomy of the lateral bands. RA is also associated with lung fibrosis, vasculitis, and coronary heart disease.
Explanation:
Boutonnière deformity in Rheumatoid Arthritis (RA) is noted for being associated with pathology in the MCP, PIP, and DIP joints (a) and it does indeed stem from the dorsal subluxation of the lateral cords (d). RA typically progresses by inflaming the joint capsule and synovial membrane which can ultimately lead to the severe damage or destruction of the articular cartilage. In turn, this series of events can cause joint deformations such as the Boutonnière deformity.
Methods of correcting Boutonnière deformity in RA include both surgical (b & c) and non-surgical approaches. A surgical intervention can be done through fusion of the DIP joint (b) or by performing a tenotomy of the lateral bands (c), both of which can potentially correct the deformity. It is, however, essential to note that surgical intervention is usually a last resort when other non-invasive treatments and therapies prove ineffective.
Rheumatoid arthritis is a potentially debilitating disease that also has known associations with other conditions such as lung fibrosis, vasculitis, and coronary heart disease. Unfortunately, it has no known cure, hence treatments are targeted towards alleviating symptoms, and improving overall patient quality of life.
