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...

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...

Scaphocapitate arthrodesis with lunate excision was performed for treatment of advanced Kienböck disease in 17 patients (18 wrists). Ten were women and seven men. Five were Lichtmann Stage IIIA, 12 Stage IIIB, and one Stage IV. Minimum follow-up period was 24 months; mean follow-up was 10.7 years (range 2.3 to 22 years, SD 7.1). At the latest follow-up, six patients were very satisfied, nine were satisfied and two were disappointed. Pain was significantly decreased in all cases. Wrist mobility was unchanged...

BACKGROUND: The appearance of early Kienböck disease on radiographs and magnetic resonance imaging (MRI) may be difficult to distinguish from other conditions that affect the lunate. We aimed to assess the interobserver agreement in the diagnosis of early Kienböck disease when evaluated on different imaging modalities. METHODS: Forty-three hand surgeon members of the Science of Variation Group were randomized to evaluate radiographs and 35 hand surgeons to evaluate radiographs and MRI scans of 26 patients for the presence of Kienböck disease, the lunate type, and the ulnar variance...

BACKGROUND: The Resurfacing Capitate Pyrocarbon Implant associated with proximal row carpectomy has been used to treat symptomatic advanced carpal collapse, widening the indications of proximal row carpectomy to patients with capitate head arthritis. The authors retrospectively compared their case series of implant versus carpectomy alone, analyzing whether prosthetic implant outcomes could be similar to those of proximal row carpectomy even with a higher stage of osteoarthritis. METHODS: Fifty-seven patients who underwent surgery for wrist osteoarthritis (minimum follow-up, 2 years) were selected retrospectively...

Kienbock disease (KD) is a disease of uncertain etiology, leading to chondral and osseous change in the lunate and wrist. Traditionally, Lichtman's classification of KD, based on radiographic appearances, has been used to direct treatment. Diagnostic wrist arthroscopy allows direct assessment of the lunate and surrounding articulations. Wrist arthroscopy can also serve as a therapeutic tool for performing debridement, resection, or arthrodesis procedures. The new Lichtman-Bain algorithm takes into consideration the status of the lunate, the effect on the wrist, and surgical and patient factors to guide management...

PURPOSE: Not all patients with Kienböck disease progress to collapse of the lunate and carpal malalignment, but it is difficult to determine which patients are at risk. We aimed to identify demographic or anatomical factors associated with more advanced stages of Kienböck disease. METHODS: We included all 195 eligible patients with Kienböck disease and available preoperative posteroanterior and lateral radiographs. We compared the mean age, sex distribution, mean ulnar variance, radial height, radial (ulnarward) inclination, palmar tilt, anteroposterior distance, and lunate type among the different Lichtman stages of Kienböck disease and performed ordinal logistic regression analysis...

BACKGROUND: The etiology of Kienböck's disease is controversial, and the blood supply is a possible pathogenic factor. The red lead (Pb3O4) angiography with micro-computed tomography (micro-CT) of lunate to investigate intralunate arteries has rarely been reported. This study aimed to investigate a new, reasonable, and simplified technique to study the intraosseous arterial pattern of normal lunates. METHODS: This study investigated the intraosseous arterial pattern of six normal cadaveric lunates through Pb3O4injection and three-dimensional reconstruction with micro-CT...
