All of the following are characteristic patterns of joint involvement in rheumatoid arthritis, except
A) Polyarticular involvement
B) Oligoarticular involvement
C) Symmetrical involvement
D) Involvement of the proximal interphalangeal (PIP), metacarpophalangeal (MCP) wrist, and metatarsophalangeal (MTP) joints
E) Frequent cervical spine involvement

20-90% of rheumatoid arthritis have cervical spine involvement.
Rheumatoid arthritis has polyarticular involvement (juvenile rheumatoid arthritis has oligoarticular involvement).
So I think the wrong answer is B.

Answer: B
Explanation: Clinically, rheumatoid arthritis is a symmetrical polyarthritis especially involving the PIP, MCP, wrist, and MTP joints. In many of these joints, definite articular deformities will develop over time. Cervical spine involvement is common. Rarely is an oligoarticular pattern observed.

In cervical spine also only the atlanto axial joint is involved the most.
Otherwise RA doesn't involve the axial skeleton.

No Nandrolone the most of the cases have C 3 n C 4 n C 5.

RA activity in the cervical spine begins early, with 83% of patients in prospective studies developing anterior atlantoaxial subluxation within 2 years of disease onset. Activity in the cervical spine progresses clinically and radiologically in tandem with the peripheral-joint involvement. In fact, the severity of the peripheral erosive damage is strongly correlated with the degree of structural damage in the cervical spine. Features of spinal involvement in RA include erosive synovitis, ligamentous subluxation, osteopenia, and vertebral-body fractures.

Rheumatoid involvement of the subaxial cervical spine is most often seen at the C3-4 and C4-5 levels where the facet joints and interspinous ligaments are involved along with the intervertebral disks. The C7-T1 level is also a common site for subluxation and radiographs of the cervical spine must include this area. Multilevel subluxations produce the characteristic stepladder configuration, which is found in 10-20% of patients. In most cases, subluxations are not fixed in the abnormal position. Rather, changes in alignment can be demonstrated on lateral radiographs taken during flexion and extension of the neck.

Abnormalities of the thoracic and lumbar spine are relatively rare in this disease. Destructive lesions of the vertebral bodies that may histologically resemble rheumatoid nodules have been occasionally described. These granulomatous foci involve the vertebral body and may extend to the vertebral endplates and allow collapse of subchondral bone and intervertebral disk abnormalities

Patients with RA who are receiving corticosteroid medication are predisposed to ischemic necrosis of bone. Although the femoral head is the usual site for this, vertebral bodies in the thoracic and lumbar regions of the spine can be affected. On radiography, this may be seen as vertebral collapse and fragmentation. Radiolucent fracture lines, which may accumulate gas from surrounding tissues, are an important clue to the diagnosis.

But Guys Remember one thing RA DOESNT INVOLVE DIP JOINTS FOR SOME UNKNOWN REASON
