Clasp-knife deformity is relatively common anomaly found at the lumbosacral junction and characterized by a large midline defect of the posterior arch of the sacrum (usually S1/S2 and occasionally S3) along with hypertrophy (or overgrowth) of the spinous process of vertebra above (usually L5).

畸形是较常见的袖骶部诱发；特征是骶骨后弓的中线的内层功能障碍（上会S1/S2和偶尔是S3）伴其上椎体（上会是袖5）棘突松弛（或过度生长）。

When a Clasp-knife deformity is accompanied by pain on extension secondary to protrusion of the enlarged spinous process (knife blade) into the sacral spinal c, it is called Clasp-knife syndrome.
