This study aims to measure anatomical data of the capitate bone, develop an external fixator for treating late-stage osteonecrosis of lunate through Ilizarov technique, and evaluate its biomechanical performance. We selected eight wrist joint specimens to measure various parameters of the capitate bone, including its length, the distance from the junction of capitate head and body to the proximal end, as well as the width of its proximal head and distal body. Additionally, we measured these same indicators in 107 patients who had undergone wrist X-ray examination...

This study reports the surgical technique and outcomes of tendon ball arthroplasty combined with proximal carpal stabilization using the extensor carpi radialis longus tendon for treating advanced Kienbock's disease. The collapsed lunate is excised and a tendon ball inserted as a spacer. A distally based extensor carpi radials longus graft is passed through the scaphoid, tendon ball and triquetrum, reconstructing the proximal carpal row. In total, 16 patients were included and the mean follow-up was 25 months...

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...

Background: Despite the good clinical results in the treatment of Kienböck disease with distal radius core decompression, a radiological progression to a certain degree in the long-term follow-up is possible. Is there a negative correlation between the clinical improvement of the patients and the radiological progression? Methods: We retrospectively reviewed the radiological and clinical results of 24 patients (mean age: 38 years; 10 women) treated with core decompression for Kienböck disease. The mean follow-up was 10 years...

Although various treatments for advanced stages of Kienböck's disease have been reported, clinical evidence demonstrating the efficacy of lunate resection and vascularized os pisiform transfer for Kienböck's disease is limited. Herein, we investigated the clinical and radiographic results of this procedure. We retrospectively investigated eight patients who were followed up for ≥1 year. The mean age at the time of surgery was 52 years. The mean follow-up period was 3.4 years. The preoperative and postoperative mean wrist flexion-extension ranges were 84° and 111°, respectively, and grip strengths were 18...

BACKGROUND: Negative ulnar variance is a widely accepted risk factor for the development of Kienbock disease (KD). Variation in radial inclination has been proposed as a risk factor, but evidence thus far has been inconclusive. We aim to clarify the relationship between radial inclination and KD. METHODS: A retrospective analysis of all KD patients from a single institution from 2007 to 2021 was conducted. Radiographs were reviewed to measure anatomic parameters and stage of disease...

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...

UNLABELLED: Extracorporeal shock waves are high-intensity mechanical waves (500-1000 bar) of a microsecond duration with a morphology characterized by a rapid positive phase followed by a negative phase. BACKGROUND: Extracorporeal shock waves have been used for pain treatment for various sub-acute and chronic musculoskeletal (MSK) problems since 2000. The aim of this article is to update information on the role of extracorporeal shock wave therapy (ESWT) in the treatment of various pathologies that cause MSK pain...

We report a novel sliding plate system (SPS) and its application for radial shortening osteotomy. We conceptualised, designed and introduced the SPS, which helps with precise shortening osteotomy in both radius and ulna. We implanted the SPS in a patient with Kienböck disease following a radius shortening osteotomy. The SPS was safe and efficient, and the surgical technique eliminated extra steps. The SPS affords precise shortening, optimum compression and anatomic alignment after radius shortening osteotomy...

Background  Spanning bridge plates were first popularized for fixation of complex distal radius fractures. However, indications for their use have expanded including the surgical treatment algorithm for treating conditions such as Kienböck's disease. Traditionally, initial surgical treatment of Lichtman Stages II to III Kienböck's disease included lunate decompression, unloading, and revascularization procedures. The addition of a dorsal spanning bridge plate further facilitates lunate offloading and may improve bone revascularization...

Background  Kienbock's disease is primarily seen in young adult males but has been recognized in skeletally immature populations as well. Traditional treatment strategies recommend operative treatment but high remodeling potential in children may allow conservative management. Case Description  We present the case of a 7-year-old female with 2 months of atraumatic right wrist pain who was found to have edematous signal change within the lunate on wrist magnetic resonance imaging (MRI) consistent with Kienbock's disease...

PURPOSE: Kienböck's disease consists of intrinsic and extrinsic characteristics that coalesce into a pathology with multifactorial etiology. Mechanical, morphological, and vascular factors have been identified as contributory. Radial osteotomy is one of the most commonly used surgical treatment for late-stage Kienböck's disease. Despite its frequent use and reported value, the specifics of radial osteotomy have not been described in aggregate. Our objective was to review the recent literature for descriptions of the radial osteotomy techniques used for treatment of Kienböck's disease...

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...
