cyphose cervicale prononcée avec menton au contact du sternum

CONT: Cervical flexion deformity (chin on chest deformity) is a complication of severe ankylosing spondylitis. This fixed posture of the cervical spine can cause significant difficulties with hygiene, nutrition, and forward gaze. Patients experience inability to open their mouth wide enough to maintain adequate nutrition, hygiene problems such as skin ulcers on the chin or chest, and problems with forward gaze leading to difficulties with ambulation. Psychosocial aspects of this deformity are also considerable. Surgical intervention includes posterior C[cervical]7–T[thoracic]1 extension osteotomy/fusion with sterile midprocedure halo placement. This procedure involves significant manipulation of the cervical spine, with possible catastrophic consequences.

CONT: Pesquisadores da Universidade da Pensilvânia, nos Estados Unidos apresentaram um estudo que avalia como positiva a técnica chamada de osteotomia, junto a um mecanismo de elevação de cabeça, para correção da deformidade ""queixo-no-peito"", comum em pacientes com espondilite anquilosante, doença reumática que agride as estruturas da coluna.
