Early detection of lunate necrosis is crucial. Prompt imaging like X-rays and MRI can identify subtle changes, enabling timely treatment before carpal collapse occurs.

Area of Science:

  • Orthopedics
  • Radiology
  • Hand Surgery

Background:

  • Lunate necrosis, also known as Kienböck's disease, presents diagnostic challenges in early stages.
  • Progression involves edema, condensation, fragmentation, and eventual carpal collapse.

Purpose of the Study:

  • To highlight the difficulties in reconstructing the natural course of lunate necrosis.
  • To emphasize the importance of early diagnosis and intervention.

Main Methods:

  • Review of the natural progression of lunate necrosis.
  • Discussion of diagnostic imaging modalities including X-ray and MRI.
  • Correlation of clinical findings with disease progression.

Main Results:

  • Initial stages show lunate edema with normal X-rays, progressing to fragmentation and collapse within months.

  • Carpal collapse significantly limits therapeutic options.
  • Degenerative changes can develop over years, with pain not always correlating with disease severity.

    • Conclusions:

    • Repeated follow-up with X-ray and MRI is essential for suspicious findings in early lunate necrosis.
    • Early intervention is critical to prevent irreversible carpal damage and preserve treatment options.
