Exam Master Neuro Practice Exam

In patients with complex regional pain syndrome (CRPS), especially in its advanced stages, marked osteoporosis is commonly observed. This condition can lead to significant changes in bone metabolism due to disuse, resulting from the chronic pain associated with CRPS. As the affected limb is often immobilized or used less due to discomfort, the bone density can decrease significantly over time, presenting as osteoporosis on radiographs.

Normal bone density is not typically expected in CRPS, as the chronic use of the affected area is often compromised. Callus formation commonly indicates healing of a fracture, which is not a typical finding in CRPS unless there is an associated trauma. Signs of fracture could be present if there was an injury, but CRPS itself is not defined by such findings.

Overall, in the context of CRPS, marked osteoporosis serves as a key radiographic finding that highlights the impact of chronic pain on bone health due to disuse.
