Isolated diseases of the os pisiforme is seldom described in the literature. Since 1973 wehave seen 7 patients with typical signs: pain at the region of pisiform, increased by dorsiflexion and radial deviations of the wrist and by compressing the pisiform in the palmar-dorsal plane. The diagnosis of pisiform disease is based on clinical and X-ray examination and followed by histological study after operation. Five of the seven patients came to operation for the following disorder: local, circumscribed chondrosis, chondromatosis of flexor carpi ulnaris with osteochondromatosis, atrophy of the pisiform and in the two cases aseptic osteonecrosis. After partial resection of the pisiform, once combined with Z-shaped lengthening of the tendon of Flexor carpi ulnaris or complete enucleation of the bone all patients were free of discomfort and remained so.
文献中很少描述豌豆骨的孤立性疾病。自1973年以来，我们共诊治了7例具有典型症状的患者：豌豆骨区域疼痛，手腕背屈和桡偏以及在掌背平面按压豌豆骨时疼痛加剧。豌豆骨疾病的诊断基于临床和X线检查，并在术后进行组织学研究。7例患者中有5例因以下病症接受手术：局部局限性软骨病、尺侧腕屈肌软骨瘤病伴骨软骨瘤病、豌豆骨萎缩，另外2例为无菌性骨坏死。在豌豆骨部分切除后，其中1例联合尺侧腕屈肌腱Z形延长术，另1例为骨完全摘除术，所有患者术后均无不适，且一直保持良好状态。
