Area of Science:

  • Orthopedics and Sports Medicine
  • Rheumatology
  • Radiology

Background:

  • Kienböck's disease, a condition affecting the lunate bone in the wrist, is typically unilateral.
  • Bilateral presentation of Kienböck's disease is exceptionally rare, prompting investigation into potential contributing factors.
  • Understanding risk factors for bilateral Kienböck's disease is crucial for diagnosis and management.

Observation:

  • A case series of five patients with bilateral Kienböck's disease was analyzed.
  • Patient demographics included manual laborers, a housewife, and individuals with long-term steroid use for autoimmune conditions.
  • Ulnar variance measurements were recorded for all patients.

Findings:

  • The mean ulnar variance in the observed cases was 1.8 mm (range 0-5 mm).
  • None of the patients presented with negative ulnar variance.
  • This suggests negative ulnar variance is not a primary risk factor for developing bilateral Kienböck's disease.

Implications:

  • The findings challenge the established role of negative ulnar variance as a sole predictor for Kienböck's disease.
  • Further research is needed to identify other potential etiological factors for bilateral Kienböck's disease.
  • This study contributes to a better understanding of rare wrist pathologies and their risk profiles.
