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...

The aim of this study was to assess the results of capitate osteotomy and transposition for stage III Kienböck's disease. Capitate osteotomy and transposition combined with an autologous iliac bone graft was carried out in 17 patients. At the final follow-up for a mean of 68 months (range 16-127 months) after surgery, the mean visual analogue scale score was 0.6 (range 0-5). The mean Wrightington wrist function score was 8. The mean grip strength was 79% of the unaffected side. There were 16 satisfactory results...

PURPOSE: Titanium lunate arthroplasty (TLA) for Kienböck disease was introduced in 1984 to address the silicone-wear particle problem common to silicone lunate implants. We sought to study the outcome of TLA. METHODS: We identified 11 patients from our hospital database who had undergone TLA between 2001 and 2010. We evaluated pain, range of motion (ROM), function, and radiological outcome at a mean 11 years after surgery. We compared preoperative ROM and radiological findings with final follow-up in the ipsilateral wrist and also made comparisons with the contralateral wrists...

Kienböck's disease, also known as avascular necrosis of the lunate bone describes the slowly progressive osteonecrosis of the lunate bone with secondary development of osteoarthritis and carpal collapse. In order to emphasize the atraumatic origin of the disease, this is normally referred to as aseptic, idiopathic or avascular lunate necrosis. There are thought to be a number of factors predisposing to Kienböck's disease, such as ulnar negative variance, the shape of the lunate itself and various types of vascular anatomy...

Purpose  This study aims to compare the outcomes and complications of our technique for nonspanning total wrist arthrodesis using a locking plate with the standard carpometacarpal spanning technique. Methods  A retrospective review of charts was performed to identify patients who underwent total wrist arthrodesis by the senior author (S.W.W.). We compared the outcomes of 15 cases of nonspanning wrist fusion with a 2.4/2.7 mm locking T plate to 11 cases of spanning wrist fusion with a 2.7/3.5 mm locking compression plate...

Kienböck disease is uncommon in skeletally immature patients. Although there is no gold standard treatment for Kienböck disease in the skeletally immature patient, surgical and nonsurgical treatment options have been shown to be effective. Initial immobilization with a cast, protection with an orthosis, and avoidance of repetitive forceful activities have been shown to be effective in some cases. Surgery may be offered to the skeletally immature patient when nonsurgical treatment is ineffective. Among several surgical techniques used for treatment in the skeletally immature patient with Kienböck disease, distal radial osteotomies have been the most frequently performed surgery; however, radial overgrowth is a concern...

Kienböck's disease is characterised by avascular necrosis of the lunate bone, and over the years it has been a challenging disease to manage, with differing opinions on the best intervention. We present an interesting case of a metallic unconstrained lunate replacement that is still functioning well in a patient 40 years after surgery. This case report represents the longest follow-up of any such prosthesis.

Proximal row carpectomy (PRC) is a well-accepted procedure for the treatment of degenerative lesions of the wrist and advance Kienböck disease. This procedure has been classically described as an open procedure but recently has been reported as an arthroscopic one. Arthroscopic PRC has several advantages such as minimal damage to the dorsal and volar ligaments as well as there being no need to detach the capsule, which can facilitate earlier mobilization and can decrease postoperative stiffness. In addition, there is a reduced risk of the interosseous posterior nerve being injured, and the proprioception system continues to function...

RATIONALE: Idiopathic avascular necrosis of the scaphoid or lunate bone are known as Preiser disease and Kienböck disease, respectively. Although there are reports of avascular necrosis involving more than one carpal bone, concurrent idiopathic avascular necrosis of the scaphoid and lunate bones is rare, with only five cases reported in the English literature (including the two herein). Although the optimum treatment for Preiser disease with concomitant Kienböck disease has not been established, our cases underwent closed radial wedge osteotomy based on the evidence of satisfactory outcomes for treating Kienböck disease...

CASE: We describe the case of a 40-year-old man with Minnaar type-III congenital synostosis of the lunate and the triquetrum who presented with Lichtman stage-I Kienböck disease. Surgical treatment consisted of capitate shortening with a capitate-hamate fusion. CONCLUSION: This case demonstrates the tenuous regional nature of the vascularity to the lunate, even in the setting of a complete lunotriquetral synostosis.

Stage IIIc Kienböck's disease is a clinical challenge to treat collapse of the lunate bone. A new reconstructive surgery was described in one patient using 3D printing lunate prosthesis. The prosthesis shape was designed by tomographic image processing and segmentation using technology compared with the intact side matched by mirror symmetry and 3D post-processing technologies. The patient recovered nearly full range of motion of the wrist after 12 months. The visual analog scale scores and Cooney scores were 2 points and 91 points...

BACKGROUND: Radius osteotomy is one of the standard surgical procedures for the treatment of Kienböck's disease. Unfortunately, radius osteotomy can result in an incongruous distal radio-ulnar joint (DRUj) postoperatively, because the procedure is performed proximal to the DRUj. METHODS: A very distal radius wedge osteotomy was performed as a 15-degree lateral closing wedge osteotomy with the apex of the wedge distal to that of conventional lateral closing wedge osteotomy; this procedure was developed to avoid postoperative incongruous DRUj...
