Area of Science:

  • Orthopedics
  • Radiology
  • Hand Surgery

Background:

  • Kienböck's disease involves the avascular necrosis of the lunate bone in the wrist.
  • Incidental diagnosis of Kienböck's disease is uncommon, with limited data on its clinical presentation and management implications.
  • Previous clinical or radiographic examinations and treatments were absent in the reviewed patient cohort.

Purpose of the Study:

  • To review the clinical and radiographic findings of patients with incidentally diagnosed Kienböck's disease.
  • To evaluate the necessity of treatment for Kienböck's disease when diagnosed incidentally with mild symptoms.

Main Methods:

  • Retrospective review of 14 patients with incidentally diagnosed Kienböck's disease.
  • Analysis of radiographic examinations obtained for unrelated conditions (e.g., carpal tunnel syndrome, Colles' fracture, osteoarthritis).

  • Assessment of clinical symptoms, impact on daily activities, and treatment requirements.

    • Main Results:

    • Kienböck's disease was incidentally diagnosed in 14 patients via radiographs taken for other medical reasons.
    • Radiographic findings indicated advanced Kienböck's disease in most patients.
    • Despite advanced radiographic changes, patients reported mild symptoms, with no limitations in daily activities or work, and required no specific treatment for Kienböck's disease.

    Conclusions:

    • Incidental diagnosis of Kienböck's disease can occur in patients with minimal symptoms and functional limitations.
    • The presence of advanced radiographic changes does not always correlate with significant clinical impairment.
    • Treatment decisions for Kienböck's disease should be individualized, considering the potential for long-term asymptomatic progression.
