Concomitant Kienböck's and Preiser's diseases: a case report.

Area of Science:

• Orthopedic Surgery
• Hand Surgery
• Radiology

Background:

• Avascular necrosis of the carpal bones is uncommon.
• Simultaneous involvement of multiple carpal bones is exceptionally rare.
• Kienböck's disease affects the lunate; Preiser's disease affects the scaphoid.

Observation:

• A 50-year-old woman presented with symptoms suggestive of carpal bone avascular necrosis.
• She had a remote history of steroid use.
• No history of significant trauma or systemic inflammatory disease was reported.

Findings:

• The patient was diagnosed with simultaneous Kienböck's disease and Preiser's disease.
• This represents a rare occurrence of avascular necrosis in two distinct carpal bones.
• Imaging confirmed the diagnosis in both the lunate and scaphoid bones.

Implications:

• This case highlights the possibility of concurrent carpal avascular necrosis.
• It suggests that steroid use, even remote, may be a contributing factor.
• Further investigation into the pathogenesis of multifocal carpal avascular necrosis is warranted.
