Kienböck disease is a condition characterized by avascular necrosis of the lunate bone. Advanced imaging can aid in the diagnosis and staging of Kienböck disease. Magnetic resonance imaging (MRI) is an important adjunct to diagnosis. In particular, MRI is helpful early in the disease when plain radiographs may not reveal abnormalities. A 17 -year-old man with Kienböck disease who underwent radiography and MR is described in this article.

Traumatic lesions of the wrist occur frequently and may give rise to underdiagnosed secondary abutment syndromes. The latter are a common cause of incapacitating pain and limited range of motion, despite minimal or even absent alterations on radiographs. Moreover, the complex wrist anatomy often results in ignorance or underappreciation of these syndromes.This paper presents a pictorial review of frequent and rare secondary abutment syndromes at the wrist joint, which – in contrast to primary abutment syndromes – are not based on anatomical variants or congenital deformations. The merit of each imaging modality is briefly mentioned.

“…The staging of Kienbock's disease is the basis for the development of treatment programs. Currently, the Lichtman classification is the most widely used staging method 2,3) , and divides Kienbock's disease into four stages. Among these, stage IIIb is the most serious, and fractures progress to sclerosis and/or collapse 4) .…”

This study aims to determine the biomechanical changes and basis for treatment using two surgical methods (scaphotrapeziotrapezoid [STT] fusion and capitoscaphoid [CS] fusion) for stage IIIb lunate necrosis. Eighteen fresh frozen upper extremities of adult cadavers were randomly divided into three groups. In group A, only the radioscaphoid and radiolunate spaces were exposed to place pressure sensors. Groups B and C underwent STT and CS fusion, respectively. The advanced I-scan pressure measurement system was used. Piezoelectric films were placed at the radioscaphoid and radiolunate spaces of wrist joints, and connected to the computerized I-scan system, which was then connected to a biaxial hydraulic material testing system (MTS). Pressure (up to 100 N) was applied to the wrist in inferior neutral position at a 10 N/s compression rate. The pressure distribution, pressure loading, and other data on the radioscaphoid and radiolunate articular surfaces for each sample were dynamically recorded and analyzed. After application of pressure with the wrist in neutral position, the radioscaphoid and radiolunate pressure values of the normal wrist group A were 41.39 ± 6.93 N/cm 2 and 39.22 ± 6.61 N/cm 2 , respectively; those of the STT arthrodesis group B were 83.89 ± 11.27 N/cm 2 and 22.55 ± 11.27 N/cm 2 ; and those of the SC arthrodesis group C were 86.45 ± 8.10 N/cm 2 and 34.11 ± 8.10 N/cm 2 . Compared with CS fusion, STT fusion surgery has much greater value in preventing rotatory semidislocation of the scaphoid bone, as well as in maintaining the stability of the wrist. It is the preferred surgical treatment for stage IIIb lunate necrosis.

Imaging of Kienböck Disease

Abstract: Kienböck disease is a condition marked by avascular necrosis of the lunate bone. MRI is useful in diagnosis and staging and should be considered, after conventional radiography, for patients with suspected Kienböck disease.
