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...

BACKGROUND: Radius osteotomies showed favorable clinical outcome in Kienböck's disease. However, few articles have been published on the long-term outcome of lateral wedge osteotomy of the radius in patients with advanced stage Kienböck's disease. METHODS: Eleven patients with Lichtman stage IIIB/IV Kienböck's disease (group A; mean follow-up period, 86.1 months; range, 48 to 163 months) and 14 patients with Lichtman stage IIIA Kienböck's disease (group B; mean follow-up period, 85...

Spontaneous rupture of the digital extensor tendons of the hand has been reported after Kienbocks disease, rheumatoid arthritis, Vaughan-Jackson syndrome, distal radial fracture. Rupture may also occur as a consequence of unrecognized carpal lunate fracture. We present a case report of a man affected with spontaneous rupture of the digital extensor tendons secondary to unrecognized carpal lunate fracture with partial dorsal dislocation. The edges of the tendon were debrided and sutured using a locked modified Kessler suture...

BACKGROUND: Carpometacarpal joints can be affected by traumatic or degenerative pathology. Although different techniques have been described to treat these conditions, most authors agree that arthrodesis is an effective treatment modality. Vascularized bone grafts of the distal radius have been used to treat carpal conditions, such as scaphoid nonunion or Kiënbock disease, and they have been shown to have several advantages over nonvascularized bone grafts. METHODS: We report a case of a carpal boss in a female patient treated with an arthrodesis of the second and third carpometacarpal joints by using the fourth extensor compartment artery vascularized bone graft...

The aim of this study was to determine and analyze the functional and radiographic outcomes after proximal row carpectomy (PRC). We hypothesized that this surgery could restore wrist mobility and function in case of radiocarpal osteoarthritis or severe carpal trauma. Sixty-two patients who had undergone PRC were included in this study: 44 patients with wrist osteoarthritis (11 SNAC, 24 SLAC, 3 Kienböck's disease, 6 other) and 18 patients with severe carpal trauma. Each patient underwent clinical (pain, range of motion, grip strength, functional scores) and radiographic evaluations...

Kienbock's disease, or avascular necrosis of the lunate, is a progressive disease ultimately resulting in end-stage arthrosis of the wrist. Various surgical treatments are available for different Lichtman stages of disease. We review the surgical options and indications, expected radiologic post-operative appearance, as well as detail potential surgical complications, as they relate to Kienbock's disease.

REVIEW
Murphy M Steiner, James H Calandruccio
Orthobiologics are not used as frequently in the hand and wrist as in other sites. The most frequently reported is the use of bone morphogenetic protein for the treatment of Kienböck disease. Animal studies have described improved tendon healing with the use of platelet-rich plasma (PRP), but no clinical studies have confirmed these results. PRP has been reported to produce improvements in the outcomes of distal radial fractures and osteoarthritis of the trapeziometacarpal in small numbers of patients. The use of orthobiologics in the hand and wrist are promising, but clinical trials are necessary to establish efficacy and safety...

INTRODUCTION: Functional results of four surgical techniques to resolve the IIIB-IV Litchman's stage of the Kienböck disease were analyzed. We observed the evolution from 2000 to 2015. MATERIAL AND METHODS: Transversal retrospective study of 33 patients treated with different surgical techniques and evaluated with Quick-DASH scale, dynamometer and EVA. RESULTS: Less functional limitation was found in the patients who underwent the intercarpal fusion with or without neurotomy of the posterior interosseous...

The midcarpal joint can be classified into two anatomical types - Viegas type I and Viegas type II - based on the absence or presence of a medial facet for the hamate on the lunate (lunohamate facet). Type I is associated with a round capitate shape, which theoretically allows better congruence with the lunate fossa of the distal radius following proximal row carpectomy (PRC). This morphological feature has never been considered as a predictive factor of clinical outcome for this surgical procedure. This study aimed to compare the clinical and radiological outcomes of the two Viegas types following PRC...

Kenrick Turner, Nicholas N Sheppard, Samuel E Norton
BACKGROUND: Spontaneous flexor tendon rupture is rare and most common in the little finger. The pathogenesis of spontaneous tendon ruptures is unclear but may occur through attrition or mechanical abrasion over a bony prominence. Kienböck disease is avascular necrosis of the lunate, with an unknown etiology. METHODS: We present a case of spontaneous rupture of flexor digitorum profundus due to Kienböck disease, which we believe is the first recorded case of flexor tendon rupture attributable to osteonecrosis of the lunate...

A technique for using an x-ray detectable radiopaque element from a surgical sponge to assess the adequacy of debridement of carpal bone cysts, Kienböck disease (lunate avascular necrosis), enchondroma of the digits, and scaphoid nonunions is described. The technique is simple to perform, inexpensive, and presents minimal additional risk to the patient. The technique has been used over the past 16 years and has enabled adequate debridement of these hand and wrist maladies by radiographically demonstrating the adequacy of the debridement to be bone grafted...

Kienböck disease is an aseptic osteonecrosis of the lunate, which gradually leads to total carpal collapse. Lichtman's classification relates radiographic evidence of wrist damage to four different stages and supports surgical decision-making. This study pertains to six patients (2 males and 4 females) affected by stage IV Kienböck's disease who underwent proximal row carpectomy and received an RCPI implant. The clinical outcomes consisted of wrist range of motion (ROM), pain on a VAS scale (0-10), the DASH score and the patient's level of satisfaction...

Kienböck disease typically presents with wrist pain, swelling, restricted range of motion, and difficulty in performing activities of daily living. Because the etiology and evolution of disease remain unclear, broad ranges of treatments have been designed. Percutaneous cementoplasty is expanding its role for managing painful bone metastases outside the spine. We can draw a parallel between lytic tumoral lesions and Kienbock's disease. Increasing the strength and rigidity of lunate with cementoplasty can prevent it from collapse, relieve the symptoms associated with the process of avascular necrosis, and increase the wrist range of motion...

INTRODUCTION: Kienböck's disease is rare in patients with a neutral or positive ulnar variance. In these situations, treatment is challenging and controversial. Various intracarpal shortening osteotomy (ICSO) procedures have been proposed. OBJECTIVE: Study the effect of the type of ICSO (isolated capitate osteotomy or combined with hamate osteotomy) on the clinical and radiological outcomes in a retrospective series. METHODS: Patients with Kienböck's disease were treated with ICSO...
