Rotatory subluxation of the scaphoid

Area of Science:

• Orthopedic Surgery
• Radiology
• Rheumatology

Background:

• Rotatory subluxation of the scaphoid is an uncommon wrist abnormality.
• It is often difficult to diagnose and can lead to severe radio-carpal arthritis if mismanaged.

Observation:

• This condition can complicate wrist trauma, particularly in the context of lunate-perilunate dislocations.
• It may also occur without trauma, associated with conditions like rheumatoid arthritis and Kienböck's disease.

Findings:

• The paper discusses the underlying mechanisms of scaphoid rotatory subluxation.
• Eight illustrative cases highlight the varied presentations, symptoms, and diagnostic challenges.

Implications:

• Emphasizes the critical importance of early diagnosis for scaphoid rotatory subluxation.
• Proper management is essential to prevent debilitating radio-carpal arthritis.
• Understanding this condition is key for effective treatment of wrist injuries and inflammatory conditions.
