Objective Joint Examination

Status localis

Objective examination of the joints is a sequential physical examination process that includes assessment of external appearance, palpation, and testing of articular function. The primary goal is to identify signs of inflammation and degenerative changes and to determine the distribution of articular syndrome.

Characteristics of articular syndrome

When describing joint lesions, three main criteria must be considered:

  • Quantitative: monoarthritis (1 joint affected), oligoarthritis (2–3 joints), or polyarthritis (multiple involvement).
  • Topography: symmetrical or asymmetrical involvement.
  • Caliber: which joints are predominantly involved — small or large.

Examination algorithm and status assessment

The examination is performed in a strict top-down sequence. For each joint, the local status (status localis) is described:

  1. Appearance: presence of swelling, deformation (bony changes), or defiguration (soft tissue edema).
  2. Signs of inflammation: erythema and local hyperthermia.
  3. Skin manifestations: rash, nodules.
  4. Palpation and function: tenderness, range of active and passive motion, presence of contractures.

Specific shape changes

The appearance of the joints and hands often points to a specific pathology:

  • Rheumatoid arthritis: ulnar deviation ("walrus fin"), swan-neck and boutonnière finger deformities.
  • Osteoarthritis: Heberden's nodes (distal interphalangeal joints) and Bouchard's nodes (proximal interphalangeal joints).
  • Ankylosing spondylitis: marked kyphosis ("supplicant's posture").

Cutaneous and systemic manifestations

Inspection of the skin and mucous membranes aids in differential diagnosis:

  • SLE: malar "butterfly" erythema on the face.
  • Dermatomyositis: periorbital edema and erythema ("heliotrope rash" / "spectacle" sign).
  • Systemic sclerosis: mask-like facies, "purse-string" sign, microstomia.
  • Gout: tophi (urate crystal deposits).
  • Psoriatic arthritis: psoriatic plaques on the elbows, scalp, and in skin folds.

Palpation and functional tests

Palpation confirms examination findings and evaluates local hyperthermia. Diffuse tenderness indicates synovitis, while localized tenderness along the joint line indicates osteoarthritis or meniscal pathology.

Functional assessment includes goniometry (measuring angles) and specific tests:

  • Hand: ability to make a fist until fingers touch the thenar and hypothenar eminences.
  • Spine: touching the chin to the sternum (cervical spine), forward flexion touching the floor (lumbar spine).
  • Sacroiliac joints: compression and distraction tests to detect sacroiliitis.
How to memorize

To remember the examination algorithm: "Top to bottom, from function to skin" — first assess symmetry top to bottom, then shape and function, and finally look for clues on the skin and mucous membranes.

Class and exam questions

What is the difference between joint deformation and defiguration?

Deformation is a persistent, irreversible change in shape due to bony overgrowth, destruction, or subluxation. Defiguration is associated with reversible soft tissue changes (edema, effusion) and gross synovial membrane changes.

What are enthesopathies?

This is inflammation of the sites where tendons, ligaments, or joint capsules attach to bone (enthetos), presenting with tenderness (e.g., of the Achilles tendon). Characteristic of spondyloarthropathies.

Where are Heberden's and Bouchard's nodes located?

Heberden's nodes are located in the area of the distal interphalangeal joints, and Bouchard's nodes are at the base of the middle phalanges (proximal interphalangeal joints). These are markers of osteoarthritis.
