Summary

This study describes a unique radiographic finding in a patient with arthritis mutilans, proposing the term "pseudoarthroplastic hand" for this condition. This terminology aids in identifying specific post-surgical changes in affected hands.

Area of Science:

  • Rheumatology
  • Orthopedic Surgery
  • Radiology

Background:

  • Arthritis mutilans is a severe, destructive form of psoriatic arthritis.
  • Radiographic evaluation is crucial for diagnosing and monitoring arthritis mutilans.
  • Previous surgical interventions can alter the typical radiographic appearance of hand deformities.

Observation:

  • A 46-year-old male patient presented with clinical and radiographic features of arthritis mutilans.
  • The hand radiographs revealed an unusual appearance suggestive of prior surgical procedures.
  • This specific radiographic pattern was not previously well-defined in the literature.

Findings:

  • The study proposes a new term, 'pseudoarthroplastic hand,' to describe this distinct radiographic finding.

  • This finding represents a unique radiological manifestation in the context of arthritis mutilans and prior surgery.
  • The term aims to improve communication and recognition of these specific radiological changes.

    • Implications:

    • The 'pseudoarthroplastic hand' designation can enhance diagnostic accuracy in complex cases.
    • This terminology may aid in differentiating post-surgical changes from disease progression in arthritis mutilans.
    • Further research is warranted to validate and explore the prevalence of this radiographic finding.
