BACKGROUND: The purpose of this study was to use micro-computed tomography to demonstrate the intraosseous vascularity of the lunate within a three-dimensional orientation to identify areas of greatest perfusion and define vascular "safe zones" for surgical intervention. METHODS: Fourteen upper extremities were injected with a lead-based contrast agent. The lunates were harvested and scanned using a micro-computed tomography scanner. The intraosseous vascularity was incorporated into a three-dimensional image...

The assessment and management of Kienböck Disease (KD) has always been a conundrum. The Lichtman classification has traditionally been used to guide treatment based on imaging. Arthroscopy provides a direct visualization of the articular surface, allows probing of the surfaces, and enables minimally invasive techniques to be performed. The Lichtman-Bain classification is a new classification that takes into account the osseous, vascular, and cartilage aspects of the lunate and the secondary effects on the wrist...

Kienböck disease is a condition that typically occurs in the "at-risk" patient, in the "at-risk" aspect of the proximal condyle of the "at-risk" lunate. In the active male, repetitive loading causes the stress fracture that commences in the single layer proximal subchondral bone plate. The lunate fracture commences at the point the lunate cantilevers over the edge of the distal radius, and then takes on the shape of the radius. We postulate that the stress fracture violates the parallel veins of the venous subarticular plexus-leading to localized venous hypertension and subsequent ischemia and edema of the fatty marrow...

Background: The etiology of multifocal osteonecrosis is not definitively known; however, hypercoagulable state is a very plausible cause. Methods: We present an unusual case of a 12-year-old boy with a history of Legg-Calve-Perthes disease presenting with right wrist pain who was subsequently diagnosed with Kienbock's disease. The finding of multifocal osteonecrosis prompted testing for a hypercoagulable state that was positive for Factor V Leiden thrombophilia. A thorough literature review using Medline database was conducted to investigate associations between inherited hypercoagulable states and multifocal osteonecrosis...

Coronal plane fracture of lunate in Kienböck disease is a challenging problem with no proven treatment. We present a technique for the treatment. A vascularized bone graft from the distal radius employing the fourth and fifth extracompartmental artery pedicles is used as a mechanical support in order to enable fracture union. The technical pearls and pitfalls are described and a clinical case is presented.

BACKGROUND: Distal radius radiographic indices may play a role as risk factors in pathogenesis of Kienbock's disease, scaphoid fracture and nonunion. Perilunate fracture dislocations are devastating wrist injuries, and their relationship and distal radius indices have not been addressed in the literature. OBJECTIVES: The aim of this study was to evaluate the possible role of distal radius radiographic indices including radial height, radial inclination, ulnar variance and volar tilt as risk factors in the perilunate fracture dislocation injury of the wrist...

Treatment of Kienböck's disease has historically been determined by staging, ulnar variance, and presence or absence of arthritic changes. With the advent of newer techniques of vascularized bone grafting, the status of the cartilage shell of the lunate has become another factor that can influence the procedure performed. The purpose of this article is to describe the technique of Kuhlmann vascularized bone graft for Kienböck's disease. In addition, the indications, contraindications, and outcomes are described...

We retrospectively reviewed 12 patients (3 men and 9 women, with a mean age of 72 years) who were surgically treated for carpal tunnel syndrome associated with Kienböck disease. All patients except 1 were incidentally diagnosed with Kienböck disease and had little or no wrist pain. Radiographic tests revealed advanced Kienböck disease in all patients. Intraoperative findings indicated that the site of maximum compression on the median nerve was located at the level of the carpal tunnel inlet in 11 patients, and the volar dislocated fragment of the lunate was located proximally adjacent to the floor of the carpal tunnel inlet...

Seventeen fresh lunates with stage III Kienböck's disease were scanned with micro-computed tomography. Four regions of interest were selected to measure trabecular parameters, which were compared with those from normal lunates. Within the three regions in the distal surface, there was more compact trabecular bone in the middle region when compared with the palmar and dorsal regions. In the central part, the trabeculae of the Kienböck's lunates were much thicker than those in normal lunates. The diameters of the palmar nutrient foramina of the Kienböck's lunates were significantly smaller than those in normal lunates...

Kienböck disease, or lunate avascular necrosis, can lead to chronic wrist pain and instability. Its etiology appears to be multifactorial including variations in adjacent anatomical structures, interrupted blood supply, and trauma. Capitate-hamate fusion is the second most commonly diagnosed carpal coalition and not treated unless symptomatic. Coalitions may alter the wrist mechanics depending on their extent. No prior reports have associated Kienböck disease with capitate-hamate coalition. We present 2 cases with congenital capitate-hamate fusion and lunate AVN...

BACKGROUND: The cause and treatment of Kienböck disease is controversial. No treatment algorithm has been accepted. We surveyed US hand surgeons to determine trends and attitudes regarding the treatment of Kienböck disease. METHODS: An online questionnaire was created focusing on specific treatments of Kienböck disease. The survey included 6 questions regarding the cause of disease, preferred vascularized bone grafting (VBG) procedure, and treatment of stages I, II, IIIA, and IIIB...

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 case of Kienbock's disease with lunate excision and filling of defect by coiled palmaris longus muscle and tendon unit...

INTRODUCTION: Proximal row carpectomy (PRC) is an option as a salvage procedure in late stage Kienböck's disease. In this study, we hypothesize that interposition of a dorsal capsular flap following PRC improves functional outcomes. No comparative study is available to assess whether interposition is effective from the functional perspective. This study aims to determine whether the addition of this procedure may improve functional outcomes at a one year assessment. METHODS: Thirty adult patients with IIIA and IIIB Lichtman stages, aged 18-54 years, were randomized into two study groups...
