REVIEW
Shashank S Dwivedi, Kevin C Chung
Kienbock disease, or avascular necrosis of the lunate, is an uncommon cause of a painful and stiff wrist. Management options range from conservative treatment in the form of immobilization and corticosteroid injections to a wide variety of surgical treatments that depend on the structural integrity of the lunate, intercarpal relationships, and the condition of the articular cartilage of the wrist. A particularly difficult problem lies in the management of young patient in whom vascularized bone grafting of the lunate has failed but in whom arthritis has not yet developed...

Deep-learning (DL) algorithms have the potential to change medical image classification and diagnostics in the coming decade. Delayed diagnosis and treatment of avascular necrosis (AVN) of the lunate may have a detrimental effect on patient hand function. The aim of this study was to use a segmentation-based DL model to diagnose AVN of the lunate from wrist postero-anterior radiographs. A total of 319 radiographs of the diseased lunate and 1228 control radiographs were gathered from Helsinki University Central Hospital database...

Kienböck's disease is a rare condition in the pediatric age group, with little agreement on its natural history and the best treatment option. Typically, these patients present with vague wrist pain and a variable degree of joint motion restriction. Diagnosis is mainly based on clinical suspicion and MRI findings, as radiographs do not show significant changes in the early stages of the disease. Prognosis is better in children than in adults due to the good healing capacity in this age group. This study will report on an 11-year-old boy diagnosed with Kienböck's disease who underwent surgical treatment to temporarily offload the diseased lunate...

A young 22-year-old male presented with complaints of pain, tingling, and numbness over his right wrist for 1 year and had a history of falls on his outstretched hand. Radiological evaluations such as X-rays were done, which showed a break in the proximal carpal arc. An MRI of the affected wrist was done. MRI findings are suggestive of avascular necrosis of the lunate along with lunate dislocation with marrow edema/contusion in the lunate. Complete disruption of the scapholunate, lunotriquetral, and radioscaphocapitate ligaments was noted...

Background  Concomitant severe radiocarpal (RC) arthritis with asymptomatic or minimally symptomatic distal radioulnar joint (DRUJ) arthritis can be debilitating for patients. Surgical management of these combined arthritides can pose a dilemma for surgeons and patients. The purpose of this study was to evaluate patients with concomitant RC and DRUJ arthritides who underwent only total wrist arthrodesis (TWA) to determine the need for subsequent surgical management of preoperative asymptomatic/minimally symptomatic DRUJ arthritis...

BACKGROUND: Avascular necrosis of the lunate (Kienböck's disease) is rare and one of the main causes of progressive painful arthritis, requiring surgical intervention. Various approaches have shown benefits in treating Kienbock's disease but with limitations. The article aims to analyze the functional outcome using lateral femoral condyle free vascularized bone grafts (VBGs) as the first choice of treatment for Kienböck`s. MATERIALS AND METHODS: This was a retrospective analysis of 31 patients with Kienbock's who had microsurgical revascularization or reconstruction of the lunate between 2016 and 2021 using either corticocancellous or osteochondral VBGs from the lateral femoral condyle...

BACKGROUND: Idiopathic avascular necrosis of the lunate is known as Kienböck's disease and that of the scaphoid is known as Preiser's disease. Because the prevalence of coexisting Kienböck's and Preiser's diseases is very low, standardized stages of disease and treatments are not established. CASE PRESENTATION: We report coexisting avascular necrosis of the scaphoid and lunate in a 68-year-old woman with no history of steroids or other risk factors. We treated her with proximal row carpectomy with capsular interposition technique...

A 12-year-old boy was tackled mid-air, resulting in a fall on the outstretched hand without fracture. The patient was treated conservatively but developed sharp pain and stiffness 6 months later. Imaging revealed distal radius avascular necrosis with physeal involvement. Owing to the injury chronicity and location, we treated the patient conservatively with hand therapy. After 1 year of therapy, the patient returned to normal activities without pain and with a resolution of findings on imaging. Avascular necrosis is more frequent in carpal bones (eg, Kienböck disease of the lunate and Preiser disease of the scaphoid)...

INTRODUCTION: Perilunate injuries are rare, complex, and high velocity trauma associated injuries accounting to <10% of wrist joint trauma. Volar peri-lunate dislocations account for <3% of these injuries. Perilunate injuries should, therefore, be focused and ruled out while examining a patient complaining wrist pain after high-energy accidents which are often missed. CASE REPORT: We report a case of, missed dislocation in a patient who presented delayed with wrist pain, post 4 months road traffic accident associated with heterotrophic ossified mass in a united scapular fracture...

INTRODUCTION: Perilunate dislocations (PLD) and perilunate fracture dislocations (PLFDs) are complex wrist injuries, resulting from high energy trauma such as motor vehicle accidents, fall from height, and extreme athletic injuries. About a fourth (25%) of PLD are missed at the initial presentation. Urgent closed reduction should be attempted in the emergency room itself to minimize the morbidity due the condition. However, if it is unstable or irreducible the patient the can be posted for open reduction...

Currently Kienböck's disease remains an 'unsolved' problem in hand surgery. Different factors have been associated with the avascular necrosis of the lunate. Mechanical, vascular and biological factors, alone or in combination, may have an influence in the aetiopathogenesis and determine the progress of the disease and even the results of the treatment. This is especially relevant in the early stages, in which conservative or surgical treatment may modify the natural history of the disease, maintaining the lunate structure and thus preserving the joint surfaces...

Correctly identifying carpal collapse is important for adequate treatment of Kienböck's disease. This study aimed to assess the accuracy of traditional radiographic indices in detecting carpal collapse to differentiate between Lichtman stages IIIa and IIIb. In 301 patients, carpal height ratio, revised carpal height ratio, Ståhl index and radioscaphoid angle were measured on plain radiographs by two blinded observers. As a reference standard, Lichtman stages were determined by an expert radiologist using CT and MR imaging...
