Radiological characteristics of Kienböck’s disease in the Korean population

Abstract

Purpose: In Kienbö ck's disease, the wrist displays certain characteristic radiological parameters, which have been reported to differ among countries. In the present study, we aimed to identify specific radiological parameters of the unaffected wrists in patients with unilateral Kienbö ck's disease and to determine the extent of the association of each parameter with the disease in Korea. Methods: This retrospective case-control study assessed the radiological parameters of patients with Kienbö ck's disease (n ¼ 53) and controls (n ¼ 53), who visited our institution between January 2000 and May 2013. Ulnar variance (UV), radial inclination, lunate fossa inclination, lunate diameter, lunate height, lunate tilting angle (LTA), lunate covering index (LCI), and Ståhl index (SI) were measured and analyzed using a binary logistic regression model. Results: We observed that wrists with a high LTA and LCI, and low UV and SI had a tendency to develop Kienbö ck's disease. Conclusion: In the Korean population, a high LTA and LCI, and low UV and SI of the unaffected wrists on plain radiography might be associated with Kienbö ck's disease. The radiographic characteristics of the unaffected wrists can differ between patients with unilateral Kienbö ck's disease and normal individuals.

Capitate osteotomy and transposition for type III Kienböck’s disease

“…The lunate is located in the central column of the proximal row and has an important mechanical role in daily activities (Taleisnik, 1976). Either decrease in height or altered shape of the lunate would be associated with a high risk of dysfunction in patients with Kienböck's disease (Kwak et al, 2017;Thienpont et al, 2004;Tsuge and Nakamura, 1993). Following the technique of Lu et al (2006), we transposed the capitate to fit closely in the lunate fossa of the distal radius and we inserted the osseous graft into the gap at the osteotomy.…”

The Surgical Importance of Morphometric Measurements Obtained from Adult Wrist Radiographs

“…'larının tek taraflı Kienböck hastalığı olan 91 hastada, hastalıktan etkilenmemiş el bileklerinin spesifik radyolojik parametrelerini tanımlamayı ve bu parametrelerin hastalıkla ilişkisinin derecesini belirlemeyi amaçladığı çalışmasında, RA, LTA, LFA, UV ölçümleri çalışma grubunda sırasıyla; 25,8°, 17,8°, 14,2° ve 0,7 mm iken kontrol grubunda ise; 26,1°, 15°, 14,1° ve 1,3 mm olarak elde edilmiştir. Ayrıca hastalar ve normal bireyler arasında etkilenmemiş bileklerde farklılıklar olduğunu belirtmişler ve LTA ve UV parametrelerini Kienböck hastalığı ile ilişkilendirmişlerdir (15).
