Kienbock disease is characterized by the idiopathic osteonecrosis of the lunate bone. Because medical nomenclature has evolved, you may encounter several alternative names in medical records or older textbooks. The most frequent synonyms include:
The existence of multiple names for Kienbock disease stems from the progression of medical history. The condition was first described by Robert Kienböck in 1910. Before his detailed radiographic analysis, clinicians often misidentified the pain and stiffness as simple wrist sprains or arthritis. As imaging technology improved, the condition was reclassified from a vague "softening" (malacia) to a specific "avascular necrosis," leading to the variety of terms currently found in international clinical databases.
For diagnostic and insurance purposes, medical professionals rely on standardized coding systems to identify Kienbock disease. In the International Classification of Diseases (ICD-10), it is typically coded under M92.2 (Juvenile osteochondrosis of hand) or M87 (Osteonecrosis). Orphanet (ORPHA:238549) and OMIM (165700) serve as the primary references for researchers, where it is officially listed under the name Kienbock disease to ensure consistency across global health registries.
