[Synovitic and enthesitic changes in the hand during reflex dystrophy]

Area of Science:

• Radiology
• Orthopedics
• Rheumatology

Background:

• Synovial reactions affect both articular and tenosynovial compartments.
• Radiographic evidence demonstrates erosions in these compartments and at entheses.

Purpose of the Study:

• To investigate the extent and characteristics of synovial reactions using low kV radiography.
• To evaluate osseous and soft tissue changes in affected compartments.

Main Methods:

• Low kV radiography in three views was utilized.
• Scintigraphic examination was employed in cases of unilateral trauma.

Main Results:

• Erosions were observed in articular, tenosynovial compartments, and at fibrous structure insertions (enthesitis).
• Localized osseous changes mimicking hyperparathyroidism were noted.
• Distal soft tissue and bone responses were more severe.

Conclusions:

• Synovial reactions manifest with erosions and distinct osseous changes in multiple compartments.
• Radiographic and scintigraphic findings highlight the widespread impact on soft tissues and bones, particularly distally.
