Kienbock's disease, which is an idiopathic osteonecrosis and collapse of the lunate bone, is an uncommon disease in children. This report describes a case of an 11-year-old girl, who presented with avascular necrosis of lunate bone confirmed by radiographic and magnetic resonance imaging evidence. After a short period of casting, the case was fully recovered within one year. The signal change w...

Abstract
 Background: In this study, we examined whether carpal bones (lunate, hamate, capitate) morphologies and fourth metecarp-capitate articulation have an effect on the distal radius fracture pattern.
 
 Methods: 206 patients who applied to emergency department with between 2016-2020 were included in study. Preoperative pre-reduction x-ray films of examined. Lunate, capitate...

Unicameral bone cyst of the lunate bone is a rare condition the incidence of which has not been described in literature. We present here a case of a symptomatic lunate cyst in a 40 year old female followed up for two years and operated in view of increase intensity of symptoms and radiological evidence of cortical thinning. The cyst cavity was filled with autologous cancellous bone graft taken ...

background: abnormal angulation of the lunate can be an indication of intercarpal pathology. on magnetic resonance images (mris) the lunate often looks dorsally angulated, even in healthy wrists. the tilt on individual slices can also be different and might be misinterpreted as pathological, contributing to inaccurate diagnoses and unnecessary surgery. the primary aim of this study was to deter...

volar lunate dislocation is the fourth and last stage of perilunate dislocation. it is an uncommon injury of the wrist and its bilateral occurrence is so rare that only one case has been reported in the literature. we are presenting the second case of this kind of wrist injury, its treatment and outcome. keywords : lunate bone, perilunate, volar plate, bilateral, dislocation.

We have performed a form of lunate replacement arthroplasty, which included excision of the lunate and insertion of a vascularised radial bone flap wrapped in pronator quadratus, for stage IIIB or stage IV Kienböck's disease, in 41 patients who have been followed up for more than three years. All patients reported an improvement in their symptoms, and 20 of the 41 became free of pain after the ...

Background: Intraosseous ganglions (IOGs) of the lunate bone are a rare cause of chronic wrist pain. Traditional treatment by open curettage and bone grafting can lead to ongoing pain and stiffness of the wrist. Objectives: In this study, an arthroscopically assisted minimally invasive technique of debridement without grafting of the lunate IOG was presented. Patients and Methods: In a prospect...

We report a case of a symptomatic unicameral (simple) bone cyst of the lunate in a 42-year- old woman. The lesion was treated with curettage and cancellous autogenous iliac bone grafting. At five years of follow-up the wrist was pain free, there were no limitations of motion, and the radiographs showed complete obliteration of the cavity. To the best of our knowledge, no other unicameral bone c...

Kienbock’s disease (lunatomalacia), first described by Robert Kienbock as ligamentous trauma to the lunate resulting in the interruption of internal arterial supply to the bone [1], is defined as a specific form of avascular osteonecrosis affecting the lunate. Kienbock’s disease is characterized by sclerosis, cystic changes, fragmentation, and articular surface collapse as present on plain radi...

Kienböck’s disease or lunatomalacia is an aseptic osteonecrosis of the lunate bone initiating a progressive collapse of the lunate bone, followed by total carpal collapse. The first description was made one hundred years ago (107). Thus far, its exact cause and natural history remain unknown (44). Several extrinsic and intrinsic factors have been investigated as to their role in the aetiology o...
