Kienböck Disease: Recent Advances in Understanding and Management

Area of Science:

• Orthopedics
• Hand Surgery
• Radiology

Background:

• Kienböck disease is a condition of lunate osteonecrosis.
• It arises from anatomical predisposition and specific trigger events.
• Understanding the disease progression is crucial for effective management.

Purpose of the Study:

• To present a unified classification system for Kienböck disease.
• To outline evidence-based treatment strategies.
• To incorporate advancements in diagnostic and surgical techniques.

Main Methods:

• Review of current literature and clinical guidelines.
• Analysis of a unified classification system for Kienböck disease.
• Integration of advanced imaging like contrast-enhanced MRI and wrist arthroscopy.

Main Results:

• Nonoperative treatments are effective for pediatric, adolescent, and elderly patients.
• Treatment for isolated lunate involvement hinges on cartilage integrity: joint leveling or core decompression for intact cartilage, and arthrodesis for disrupted cartilage.
• Advanced procedures like arthroscopy and MRI enhance diagnostic and therapeutic capabilities.

Conclusions:

• A unified classification system aids in tailoring treatment for Kienböck disease.
• Treatment decisions must consider disease staging, cartilage condition, and patient demographics.
• Modern diagnostic tools and surgical techniques offer expanded therapeutic options.
