A 55-year-old patient who clinically presented with a Heberden arthrosis and gryphosis of the second and fourth finger nails of the left hand was admitted to our outpatient department under the tentative diagnosis of psoriatic arthritis. Nature of nail damage and combination of clinical findings suggested the diagnosis of a pincer-nail syndrome. The pathogenesis of this rare disease is not yet clear. Its complete clinical picture includes gryphosis of finger and toe nails in combination with acroosteolytic shortening of the end-phalanx and destructive arthrosis of the terminal joints of toes and fingers. Since deformation of the nail, which sometimes includes inflammation of the nail bed, may cause marked pain, surgical intervention with excision of the nail and, if necessary, revision of the nail bed has to be performed in most cases.
一名55岁患者，临床上表现为赫伯登关节病以及左手第二和第四指指甲呈钩状，在初步诊断为银屑病关节炎的情况下入住我们的门诊。指甲损伤的性质以及临床症状的组合提示为钳形甲综合征。这种罕见疾病的发病机制尚不清楚。其完整的临床表现包括手指和脚趾指甲呈钩状，同时伴有末节指骨骨质溶解缩短以及手指和脚趾末端关节的破坏性关节炎。由于指甲变形（有时包括甲床炎症）可能会引起明显疼痛，大多数情况下必须进行手术干预，切除指甲，必要时对甲床进行修复。
