摘要

关节错位和尺腕嵌塞可发展为手腕骨关节炎。这可能是由舟月骨韧带(很少是月状三叉韧带)或三角纤维软骨复合体的中央凹板撕裂引起的。在退变前阶段,影像学表现不明确,症状可能不存在或不明显。同样,尺侧变异阳性可能与最初症状轻微且无影像学异常有关。本文回顾了在腕骨关节炎或嵌塞综合征发生前早期的影像学表现。韧带撕裂,软骨软化症和局灶性骨髓水肿被识别使用磁共振成像以及磁共振和计算机断层关节摄影。识别这些前体可以提高对手腕细微影像学发现的认识,这些发现可能发展为不稳定、退变或骨关节炎,并允许适当的患者咨询。

Identification of degenerative precursors at the wrist with advanced imaging: current updates.

Articular malalignment and ulnocarpal impaction can progress to osteoarthritis in the wrist. This may be triggered by tears of the scapholunate ligament (rarely the lunotriquetral ligament) or the foveal lamina of the triangular fibrocartilage complex. In the pre-degenerative stages, radiographic findings are inconclusive, and symptoms may be absent or discrete. Similarly, positive ulnar variance may be associated with symptoms that are at first mild and without radiographic abnormalities. This review presents imaging findings in the early stages before carpal osteoarthritis or impaction syndrome develops. Ligament tears, chondromalacia and focal bone marrow oedema are identified using magnetic resonance imaging as well as magnetic resonance and computed tomography arthrography. Identifying these precursors may allow raise awareness of subtle imaging findings in the wrist that may progress to instability, degeneration or osteoarthritis and allow appropriate patient counselling.
