The aim of this study was to investigate the feasibility of establishing dog models of lunatomalacia through liquid nitrogen freezing. Twelve adult crossbred dogs were divided into three groups. Unilateral lunates were peeled off the parenchyma and frozen to result in avascular necrosis. They were observed dynamically through X-ray, computed tomography (CT) and magnetic resonance imaging (MRI)....

INTRODUCTION Kienbock's disease is an osteonecrosis of lunate bone (lunatomalacia) seen more commonly in males in the second to fourth decade of life. The exact etiology is unknown and symptoms include wrist pain and stiffness of wrist. Advanced stages of disease may require lunate excision and filling of the void by various substitutes like silicone implants, tendon grafts etc. We report a cas...

J Bone Joint Surg [Br] 2008;90-B:133-9. Kienböck’s disease is a form of osteonecrosis affecting the lunate. Its aetiology remains unknown. Morphological variations, such as negative ulnar variance, high uncovering of the lunate, abnormal radial inclination and/or a trapezoidal shape of the lunate and the particular pattern of its vascularity may be predisposing factors. A history of trauma is c...

A 32 year old man, right-handed soldier, was admitted to Emergency Department two hours after undergoing right wrist injury following a 2 meter fall onto the hand, in hyperextension. Clinical examination revealed a deformity of the wrist with an obvious open lunate enucleation (A). The neurovascular status was intact. Standard radiograph of the wrist demonstrated a completely enucleated lunate,...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2014205189 DESCRIPTION Kienböck’s disease (KD) is characterised by avascular necrosis of the lunate bone and is of unknown aetiology. KD is thought to result from a combination of vascular, anatomic and traumatic insults resulting in interruption of the blood supply to the lunate and ...
