Kienbock Disease: Moving Forward

Pdf Summary

Kienböck Disease, also known as lunate osteonecrosis, is a condition that affects the lunate bone in the wrist. In recent years, new information has emerged regarding the etiology, classification, and treatment options for this disease. Advanced imaging techniques, such as gadolinium perfusion MRI, have provided more accurate ways to assess lunate viability and determine treatment options. Additionally, arthroscopy has allowed for the evaluation of articular cartilage damage and the development of a new classification system based on the number and location of nonfunctional articular surfaces. <br /><br />The treatment algorithm for Kienböck Disease now incorporates the traditional osseous classification system, the viability/perfusion classification, and the articular cartilage-based classification. Treatment options include immobilization, lunate decompression, revascularization with bone graft, lunate reconstruction or excision, and wrist fusion or arthroplasty. The choice of treatment depends on the stage of the disease, lunate viability, and articular cartilage damage. <br /><br />Recent advances in treatment options include the use of vascularized bone grafts, lunate replacement arthroplasty, and minimally invasive techniques. These newer treatments offer promising outcomes and may provide better options for patients with Kienböck Disease. However, further research is needed to determine the long-term effectiveness and outcomes of these treatments. <br /><br />Overall, the treatment of Kienböck Disease has evolved in recent years, with new information regarding etiology, classification, and treatment options. The development of more accurate imaging techniques and arthroscopic evaluation has allowed for a more nuanced treatment algorithm that takes into account lunate viability and articular cartilage damage.
