It has been reported that almost 50% of lunates have a separate medial facet on the distal surface for articulation with the hamate; about a quarter of these have erosion of the cartilage with exposed subchondral bone on the proximal pole of the hamate. We describe 4 cases of ulnar-sided wrist pain caused by hamato-lunate impingement that resulted in chondromalacia. The pain could be reproduced by a modification of the Lichtman test. The diagnosis was confirmed by arthroscopy. All 4 patients responded favorably to resection of the head of the hamate.
据报道，近50%的月骨在远侧表面有一个单独的内侧小平面，用于与钩骨关节；其中约四分之一的患者，钩骨近端极的软骨有侵蚀，软骨下骨暴露。我们描述了4例由钩月撞击导致软骨软化引起的尺侧腕部疼痛病例。通过改良的Lichtman试验可再现疼痛。关节镜检查证实了诊断。所有4例患者对钩骨头切除术反应良好。
