Kienböck’s disease: a case report

Abstract

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.

Avascular necrosis of lunate bone: Kienbock disease

“…The patients typically present with pain localized to the radiolunate facet, decreased motion, swelling and weakness in the affected hand. Pain is classically insidious in onset, often related to activity and can be present for extended periods before presentation [3]. In our case, the patient presented to ED with similar complaints.…”

“…KD is most common between the second and fifth decades of life and it affects men more than women [3]. KD is a very rare disease which is characterized by sclerosis, cystic changes, fragmentation and progressive osteonecrosis.…”

“…Patients usually have the history of recurrent trauma. Osteonecrosis of the lunate bone is most common between the second and fifth decades of life [3]. In this case, we would like to highlight a case of KD in a 28-year-old female patient without any medical or traumatic history.…”

Kienböck’s Disease Following a Hypersupination Injury: A Case Report

“…Omar et al outlined one case in which a 17-year-old male presented with atraumatic left wrist pain with radiographic findings demonstrating densification of the lunate with a flattened appearance of the scaphoid with fixed rotation and no arthritic changes [2]. An MRI confirmed signs of Kienböck's disease, including fragmentation of the lunate and T2 signal hyperintensity.…”

“…The first-line investigation depends on the clinical exam, and patients may be referred for additional imaging beyond radiographs, such as ultrasound scans, nerve conduction studies, electromyography, or magnetic resonance imaging (MRI), depending on the clinical picture [1]. However, the patient's history may trigger warning signs of rarer etiologies of wrist pain [2]. We report a case of osteonecrosis of the lunate (Kienböck's disease) that was not noted on initial radiographs.…”
