The FP made the clinical diagnosis of rheumatoid arthritis (RA) based on the patient’s bilateral MCP joint swelling, ulnar deviation, and morning stiffness.
Patients with RA initially experience swelling and stiffness in their wrists, as well as their MCP and metatarsophalangeal joints. Later, the larger joints are affected. When RA is advanced, severe destruction and subluxation occur.
Magnetic resonance imaging is helpful in identifying early RA changes, such as synovitis, effusions, and bone marrow changes. Later on, x-rays will reveal joint erosions and loss of joint space.
To treat the patient’s pain and inflammation, the FP prescribed a COX-2 inhibitor (along with a proton pump inhibitor to protect the stomach). The FP also referred her to a rheumatologist for further work-up and to determine whether a disease-modifying antirheumatic drug was in order.
