A 52-Year-Old Man With a Deforming Polyarthropathy


He had bilateral hand pain. History included rheumatic fever, aortic valve replacement, corticosteroid-induced osteonecrosis, and total left hip arthroplasty.

A 52-year-old white man presented with complaints of bilateral hand pain; he had a history of rheumatic fever, aortic valve replacement, corticosteroid-induced osteonecrosis, and total left hip arthroplasty.
The patient had been treated with oral corticosteroids and a biologic response modifier for several years for a diagnosis of rheumatoid arthritis (RA). Laboratory findings included negative antinuclear antibodies and rheumatoid factor (RF) test results and a normal erythrocyte sedimentation rate (ESR).


On examination, the patient was found to have ulnar deviation of both hands, along with mild subluxation at the metacarpophalangeal (MCP) joints, hyperextension of the proximal interphalangeal (PIP) joints, and flexion of the distal interphalangeal joints. There was no evidence of active synovitis in his hands or wrists.

X-ray films of both his hands were obtained and are seen here. A posteroanterior (PA) radiograph (top) of both hands firmly pressed against the plate shows hook erosions at the second and third MCP joints and mild periarticular osteopenia. Characteristic joint-space narrowing also is seen in the bilateral carpi. A PA radiograph (right) of both hands when lifted off the plate shows marked ulnar deviation that mimics RA and characteristic swan-necking of the first digit. In addition, an oblique x-ray view showed flexion deformities of the MCP joints.

What do the x-ray films show?

The patient had Jaccoud arthropathy, a syndrome characterized by progressive, painless, and nonerosive deformity that affects the hands and, to a lesser extent, other joints. Patients may have pain that is predominantly mechanical in nature, unlike the stiffness and pain seen in RA.This pain is the result of mechanical disruption of the normal joint and instability.

Jaccoud arthropathy most often has been described as a sequela of chronic rheumatic fever1-3; the condition also is associated with systemic lupus erythematosus and scleroderma and is known to occur in cases of Parkinson disease and lung malignancy.4 Jaccoud arthropathy has been hypothesized to be a seronegative variant of RA because cases without an antecedent history of rheumatic fever have been identified. The condition also may be the result of chronic capsular fibrosis secondary to chronic disease.5

Bywaters1 outlined criteria for the diagnosis of Jaccoud arthritis, and others modified them.The following serves as a reasonable diagnostic outline:

•A history of repetitive attacks of acute rheumatic fever distinguished from those of RA by the transient nature of polyarthritis.

•Delayed recovery, associated with stiffness of the MCP joints, which later results in the appearance of joint deformity.

•Deformity appearing to be the result of periarticular fascia and tendon fibrosis rather than true synovitis.

•Deformity consisting of (a) flexion at the MCP joints (see oblique x-ray film above) and some associated periarticular soft tissue swelling, (b) ulnar deviation most marked in the fourth and fifth digits, and (c) ulnar deviation correctable by voluntary effort in the early stages.

•Associated hyperextension at the PIP joints.

•Tendon crepitus at the MCP joints and interphalangeal joints.

•Joint disease, usually inactive, with few or no symptoms and good functional capacity.

•A normal ESR and a negative RF.

•The earliest radiographic bone changes consisting of erosion of the metacarpal head on the palmar and radial part of the circumference in an anteroposterior projection, producing hook-like
erosion. (This deformity is not entirely specific for Jaccoud arthropathy; it also occurs in RA.)

A misdiagnosis of Jaccoud arthropathy as RA is made frequently on the basis of hand deformity,
as seen in our patient. However, a careful history and physical examination supplemented by radiographic and serological tests help differentiate one from the other.


Differentiating Jaccoud Arthropathy from Rheumatoid Arthritis

Jaccoud Arthropathy
Rheumatoid Arthritis
Results from capsular and periarticular fibrosis, which also are seen in the hearts of patients with rheumatic fever
Results from inflammation of the synovial lining of the diarthrodial joints that results in pannus formation
Reversible nature of the articular deformity that is striking
Distinguished by irreversible swan-neck and boutonniere deformities at the interphalangeal joints and subluation of the wrist at the metacarpophalangeal joints, with evidence of active synovitis or effusion on examination
Radiographic findings of hook erosion in the metacarpophalangeal heads that may be produced by pressure erosion of the overlying fibrosed capsule in distored joints
Bony erosion in a juxta-articular distribution and periarticular osteopenia appearing early in the disease
Negative RF and normal ESR
Positive RF, with an elevated ESR
RF: rheumatoid factor
ESR: erythrocyte sedimentation rate
