Purpose: This prospective clinical study examined standard wrist magnetic resonance imaging (MRI) examinations and the incremental value of computed tomography (CT) in the diagnosis of Kienböck's disease (KD) with regard to reliability and precision in the different diagnostic steps during diagnostic work-up.
Materials And Methods: Sixty-four consecutive patients referred between January 2009 and January 2014 with positive initial suspicion of KD according to external standard wrist MRI were prospectively included (step one). Institutional review board approval was obtained.
Purpose: The aim of this study was to systematically review the literature on antibiotic prophylaxis in gynaecologic surgeries to prevent inflammatory complications after gynaecological operations. The study was carried out as a systematic review.
Methods: Only randomised controlled trials of women undergoing gynaecological surgery were included.
Purpose: The clinical outcomes of scaphotrapeziotrapezoid (STT) arthrodesis were compared to radial shortening osteotomy (RSO) to determine if any of the treatment methods was superior. The impact of RSO and vascularized bone grafts (VBG) on disease progression were measured based on X-rays to evaluate if a difference in Kienböck's disease (KD) progression exists.
Methods: Out of 98 consecutive patients treated between 1991 and 2013, 46 had STT arthrodesis, 21 had RSO, 7 had VBG, and 3 had VBG and RSO.
Objectives: Scientific databases index numerous references related to the treatment of Kienböck's disease; yet little is known about the nature of the disease and its pathognomonic features. This study provides a cross-sectional analysis of the pattern and extent of osteonecrosis in a large cohort and a longitudinal analysis to determine the spontaneous disease progression in single patients who have not had surgical management until fragmentation of the lunate.
Methods: In a prospective case series, the pattern and extent of osteonecrosis were correlated with the duration of symptoms in all patients with Kienböck's disease confirmed using high-resolution 3-T magnetic resonance imaging (MRI) and ultra-thin section computed tomographic (CT) scan since 2009.
Background: Multiple hypotheses regarding the cause of Kienböck disease have been proposed in seemingly contradictory small case series and cohort studies with inadequate statistical power. A prospective case-control study was conducted to analyze frequently discussed risk and causal factors.
Methods: Eighty-one consecutive patients with Kienböck disease and 198 patients with wrist ganglia were referred to the authors' clinic between 1990 and 2012, and 2003 and 2011, respectively.
Background: Negative ulnar variance has been associated with Kienböck disease, both supporting a causal link and providing a basis for therapeutic recommendations. The aim of this study was to determine whether there is a causal relationship between Kienböck disease and negative ulnar variance.
Methods: The causal relationship between Kienböck disease and negative ulnar variance was assessed using three methodologies: (1) an analysis of the quantitative and qualitative distribution of ulnar variance in a case-control study of 81 patients with Kienböck disease and a control group of 212 healthy wrists; (2) a systematic literature review and meta-analysis of six case-control studies (including the case-control study presented in this article) to test for an association between Kienböck disease and negative ulnar variance; and (3) a determination of causal relationship by using the Bradford Hill criteria.
