Kienbock’S Disease

Histopathological studies of extracted whole lunate bones obtained from 10 patients with Stage 3 Kienböck’s disease at surgery for tendon-ball replacement were correlated with magnetic resonance imaging (MRI), computed tomography (CT) and tomography images made prior to surgery. A reforming zone, or a reactive interface between the reactive new bone and granulation tissue formation, and new vascularization were observed surrounding the bone necrosis area showing empty lacunae, fatty necrosis, and disappearance of osteoid. Findings of CT, tomography and microradiography of slices of extracted lunate bone confirmed that fractures of the articular cartilage and the subchondral bone occurred secondarily by overloading, and showed the extent of the collapsed area of the lunate. MRI showed complete loss of signal intensity in T1 images of the lesion of the lunate in advanced Stage 3 Kienböck’s disease. MRI is at present unable to distinguish bone necrosis, the histological reactive interface or surrounding hyperaemia in detail. However, the low-intensity arc, or the reactive interface present on MRI in early Stage 3, sometimes correlates with the histological findings of osteoid and granulation zones.

Kienbock’S Disease

Kienbock’s disease is an avascular necrosis of the lunate bone in the wrist [1]. Current early-stage treatment techniques include joint leveling procedures, such as radial shortening and ulnar lengthening. These techniques serve to unload the radiolunate joint and redistribute compressive loads to the radioscaphoid joint [2]. Additionally, core decompression of the distal radius and ulna, first introduced by Illarramendi [3], and has been found clinically effective in improving early stage Kienbock’s disease. Clinical studies have since found radial core decompression (RCD) to be as effective as performing the procedure on both forearm bones [4]. However, there have been no biomechanical studies characterizing the changes in wrist kinematics following a RCD. The purpose of this study is to determine the changes in lunate motions following a RCD.

Kienbock’S Disease

The etiology of the necrosis of the lunate bone is still unclear. In today's theories, the necrosis is explained by impairment of the arterial bone circulation or fracture following mechanical overloading. In this study, six specimen in different stages of the disease were investigated histologically. In all the specimens, focal necrosis was detected, but also signs of regeneration, i.e. immature bone formation. No signs of fracture were seen in all stages of the disease. These findings are not compatible with sudden interruption of arterial blood supply or fracture of the lunate bone as a primary lesion. Comparable histological patterns are known in the necrosis of the femoral head. The etiological model of necrosis of the femoral head is well investigated and postulates primary marrow hypertension, induced by impairment of the venous drainage. Our results are contradictory to the etiological theories of fracture or breakdown of the arterial blood supply as a primary lesion in Kienböck's disease, and support the assumption that the model of intraosseous hypertension is transferable to the necrosis of the lunate bone.

Kienbock’S Disease

Background and Purpose Wrist swelling is a frequent clinical manifestation of Kienböck's disease, but no study has reported the site and pathology of wrist swelling in this disease. The aim of this study is to elucidate the site and pathology of wrist swelling in Kienböck's disease. Materials and Methods Dorsal and palmar soft tissue thicknesses of the wrist were measured on standard lateral radiographs of the wrist in 26 patients with Kienböck's disease and 30 subjects without intra-articular lesion. Axial magnetic resonance imaging (MRI) views were examined to detect the site of swelling. The dorsal capsular ligament in three patients with Kienböck's disease underwent histological examination. Results Radiographic study confirmed dorsal wrist swelling in 24 of 26 (92%) patients examined compared with the contralateral unaffected wrists. MRI demonstrated thickening of the dorsal capsular ligament and extensor layer with synovial proliferation. Histological examination revealed nonspecific chronic inflammation. Conclusion Dorsal wrist swelling in Kienböck's disease is a common manifestation and constitutes a part of pathology of Kienböck's disease, although further study is required to clarify the relation between wrist swelling and etiology of Kienböck's disease. Level of Evidence This is a Level III study.

Kienbock’S Disease

Forty four patients with forty seven wrists suffering from Kienböck’s disease were re-examined. The mean observation time was 20.5 years. In all forty seven wrists the treatment had been immobilization. Using a standard X-ray projection, and a reliable method of ulnar variance measuring, the ulnar variance was determined by three observers independently. Comparing the result with the ulnar variance in normal wrists we found the so-called “ulnar minus variant” overrepresented in patients with Kienböck’s disease. However, comparing X-rays taken at the time of diagnosis with X-rays at re-examination, we found in eight out of forty seven wrists that a subchondral bone formation in the distal radius opposite the lunate bone had taken place. This bone formation will tend to enhance the negative value of ulnar variance measurements, and suggests an explanation of the overrepresentation of “ulnar minus variants” in Kienböck’s disease. Excluding these eight wrists from the material and comparing the mean ulnar variance value in the remaining thirty nine wrists with the mean value in normal wrists no statistical difference was shown. Based on these observations it seems unlikely that the “ulnar minus variant” has any bearing on the cause of Kienböck’s disease.

Kienböck’s disease is a rare condition characterised by avascular necrosis of the lunate bone. Its natural history and aetiopathogenesis have not yet been clarified, nor are its triggering factors identified. We present a case of a 17-year-old male gymnast, without relevant medical/family history, with stage IIIA Kienböck’s disease diagnosed in 2016. Initially, submitted to conservative treatment that proved to be insufficient. Consequently, surgical treatment was proposed, but refused. The patient instead underwent experimental treatment with hyperbaric oxygen (120 sessions, 100% oxygen at 2.5 atm, for 70 min periods, once daily, five times per week). In April 2018, a favourable clinical and radiological evolution was observed, with an improvement in the patterns of pain, motion and strength and an almost complete involution of the process of aseptic necrosis of the semilunar. To the best of our knowledge, this is the first report of Kienböck’s disease treated with hyperbaric oxygen.
