Osseous Anatomy and Microanatomy of the Lunatelayer of proximal subchondral bone plate, which is at risk of fracture, which does occur in Kienböck’s disease. There are spanning trabeculae between the proximal and thick distal subchondral bone plate. The Kienböck’s avascular necrosis “at-risk” wrist includes a radius with negative ulnar varianceAtmosphere 发表于 2025-3-27 01:30:44

Wrist Biomechanics as Applied to the Lunate and Kienböck’s DiseaseThese conditions induce abnormal internal lunate stress, encourage progression of incomplete fractures, and cause progressive lunate collapse and localized trabecular osteonecrosis. Conversely, type II lunates appear to be protective against coronal fractures and scaphoid flexion deformities (which幼稚 发表于 2025-3-27 17:32:13
Pathoanatomy of Kienböck’s Diseaseores the pathological changes of normal bone and cartilage following trauma and an ischemic episode. With ischemia, fat cells become swollen, which compromises the venous drainage. With repeated ischemia, the marrow becomes fibrotic and scarred, which further compromises the vascularity.

The Etiology of Kienböck’s Diseasee in clinical practice with the “at risk” lunate. The fracture commences on the proximal radial aspect of the lunate and corresponds to the shape of the distal radius. There can be a coronal fracture of the lunate due to the nutcracker effect.

Radiological Risk Factors for Kienböck’s Diseasey of Kienböck’s disease has been questioned. Several authors have found a change in the ulnar variance with age, sex, and position of the wrist as well as osteoarthritis secondary to Kienböck’s disease. It seems that the nature of the control group is crucial. Two meta-analyses recently conducted coinfatuation 发表于 2025-3-28 03:21:43
Clinical Presentation, Natural History, and Classification of Kienböck’s Diseaseent plan. The disorder typically occurs in patients 20–40 years old, but can also be found in the pediatric and geriatric age groups. The classification system developed in 1977 by the senior author, and modified in 1993, provides a widely used treatment algorithm based on the structural changes thaineffectual 发表于 2025-3-28 10:02:24
Basic Imaging and Differential Diagnosis of Kienböck’s Diseaseis an imaging-based classification system, which has significant implications for treatment planning. Whereas the initially proposed Lichtman classification was based primarily on radiographical osseous findings, advancements in the understanding of computed tomography (CT) and magnetic resonance imhardheaded 发表于 2025-3-28 14:07:01
