[A case of Phalen-Dickson syndrome].

A case of dysplastic spondylolisthesis with a complete slipping of the L5 vertebrae accompanied by neurological disorders and characteristic contracture of hamstrings (Tight Hamstrings Syndrome) has been described. This disease entity, described in literature, has a name of Phalen-Dickson Syndrome. Neurological disorders were caused by compression of radices at the level of the slipping. Surgical treatment were: laminectomy of the arcus of L5, decompression of the compressed radices with postero-lateral fusion of the L5-S1 segment without reduction of the slipping. The final, functional and radiological results were good.
