Background  According to current literature, the estimated average survival rate for Remotion, the total wrist implants, is above 90% on an 8-year follow-up. We examined our series of Remotion to calculate its survival rate on a 10-year follow-up. Case Description  A total of 23 cases of total wrist implants were reviewed. The case series included 22 patients, 18 females and 4 males, of an average age of 55 years. The case series included 19 inflammatory rheumatic diseases, 3 Kienböck disease, and 1 posttraumatic arthrosis...

PURPOSE: To determine clinical outcomes of Preiser disease treated with closing radial wedge osteotomy (CRWO). METHODS: Seven patients with Preiser disease underwent CRWO. Two wrists had stage 2 disease, 3 had stage 3, 2 had stage 4 (Herbert-Lanzetta classification). Magnetic resonance imaging (MRI) showed that 4 wrists had stage 1 and 3 had stage 2 indicating complete and incomplete necrosis, respectively (Kalainov criteria), before surgery. Two wrists had concomitant Kienböck disease...

BACKGROUND: Osteonecrosis of the lunate, Kienböck's disease, can lead to fragmentation of the lunate, carpal collapse, and severe osteoarthritis. Since the etiology of Kienböck's disease is impaired circulation, a diagnostic method capable of assessing perfusion would be valuable. Recent studies have suggested that dynamic contrast-enhanced (DCE) MR examinations at 3 T can assess perfusion in healthy carpal bones. PURPOSE: To evaluate the use of DCE-MR for assessing perfusion in the lunate bone in patients with Kienböck's disease...

No surgical procedure perfectly treats advanced Kienböck disease. Although vascularized os pisiform transferring (VOPT) is one of the main therapeutic approaches, reports on long-term follow-up and case series for this technique are scarce.We collected postoperative results in 11 patients with advanced Kienböck disease who underwent VOPT between 1986 and 2001 in our Hospital. Follow-up durations ranged from 15 to 26 years.At the last follow-up, excellent and good results were found in 81.8% according to the Modified Green and O'Brien score...

There is a general consensus that the pathogenesis for Kienböck's disease remains uncertain, though it is probably related to nonphysiologic stress transmission across the lunate, acting in concert with one of several possible vascular abnormalities. Most surgical treatments focus on mechanical aspects rather than real physiopathology, but in the recent years several articles have shown the utility of vascularized grafts in the treatment of Kienböck's disease, especially in its early stages. The authors present a case of a successfully reconstruction of a IIIA stage Kienböck's disease with an osteochondral vascularized graft from medial femoral condyle...

Objective: Treatment of Kienböck's disease is challenging and the variability of results, despite the surgical technique, shows that there must be other aspects that can influence outcomes. The objective of this study is determine, through arthroscopic approach, the pattern of impairment of the carpal bones in Lichtman stage III patients. Method: Wrist arthroscopy was performed in patients with symptoms and evidence of lunate necrosis on x-rays, with signs of 3A and 3B stages...

We report two rare cases of existing or worsening symptoms due to Kienböck's disease after distal radius fracture (DRF). During examination, radiographs show changes in the lunate bone; there was persistent wrist pain after treatment for DRF. In each case, surgeries were performed: A combined therapy (bone marrow transfusion, bone peg graft, external fixation, and low intensity pulsed ultrasound) for one, as well as carpal coalition for another. The etiology of these case presentations suggest that a compression fracture of the lunate due to a DRF resulted in softening and sclerosis...

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...

BACKGROUND: Radial osteotomy has shown favorable clinical results for early to advanced stages of Kienböck disease. However, it is not clear whether this technique could change the natural course of the disease, or whether its clinical results are actually superior to those of nonoperative treatment. The purpose of this study was to compare radial osteotomy with nonoperative treatment in terms of long-term radiographic and clinical outcomes in patients with Kienböck disease. METHODS: We systematically reviewed retrospective studies of radial osteotomy and nonoperative treatment for Kienböck disease with long-term follow-up (mean of ≥10 years)...

The management of Kienböck's disease is complex and constantly evolving in parallel with progress in the understanding of the pathophysiological mechanisms of this condition. Cross-sectional imaging techniques have an essential role in the diagnosis and prognostic assessment of this disease. CT allows the optimal study of the morpho-structure of lunate bone. MRI makes it possible to study bone marrow viability. As for CT arthrography, it allows to evaluate accurately articular cartilage of the different carpal joints...

CASE: We describe a patient with Bain grade-2b Kienböck disease with a coronal fracture of the distal lunate articular surface with proximal structure collapse. To reestablish midcarpal congruity, we used a bone-anchored suture to repair the coronal split in the lunate in preparation for lunate preservation with osteochondral medial femoral trochlea (MFT) reconstruction. CONCLUSION: In Bain grade-2b Kienböck disease, lunate reconstruction of both the proximal and distal joint surfaces can be performed...

The treatment of advanced-stage Kienböck disease (KD) remains highly controversial. Particularly important is stage IIIC KD, which includes patients with a lunate coronal fracture. The purpose of this paper was to describe a new approach to KD in patients with Lichtman stage IIIC KD, and our results using it. The procedure combines a dorsolateral biplane closing radial osteotomy and lunate fixation. A total of 11 patients from January 2002 through December 2016 with documented KD who underwent this technique were included...
