JOINT infection of the joint space.
The joint contamination may be monarticular or polyarticular. Weight bearing
joints are commonly involved.
2. Erosion pattern: Soft tissue swelling and
joint effusion may comprise early findings. As the infection progresses, poorly
defined bony destruction with indistinct superficial marginal erosions may
be evident along the articular surfaces. This may be accompanied by joint
space narrowing, secondary to chondral destruction. Joint space ankylosis
may occasionally occur in advanced cases.
3. Differential diagnosis:
Advanced chondral destruction, secondary to joint sepsis, may mimic
neuropathic joint destruction.
