A cervical collar including an anterior component for coupling to a posterior component having an anatomical contour to circumferentially surround a neck, and a mandibular support having an anatomical contour and coupling to the anterior component, the anterior component having a vertical centerline (A-A) and comprising: an upper part arranged for receiving the mandibular support; a lower part connected to the upper part; a tensioning device connected to the upper part; wherein the upper and lower parts (12, 14) are secured to one another at corresponding wing portions (58, 60) thereof whereat the upper and lower parts (12, 14) pivot; at least one cable engaging between the upper and lower parts (12, 14) and arranged to be shortened or lengthened for height adjustment relative to the upper and lower parts (12, 14) by the tensioning device to move the lower part relative to the upper part; wherein the height adjustment of the upper part relative to the lower part is configured to maintain the connection of the mandibular support and the posterior component to the anterior component, without changing the anatomical contours of both the mandibular support and posterior component; wherein the cervical collar further comprises: side adjustment connections connecting the mandibular support to the upper part and defining a female component arranged at an oblique angle relative to the vertical centerline (A-A) to enable adjustment of the mandibular supprt relative to the anterior component; and a side height mechanism which secures the wing portions (58, 60) to one another and permits height adjustment of the wing portions (58, 60) relative to one another and including a female component arranged parallel to the vertical centerline (A-A). an upper part arranged for receiving the mandibular support; a lower part connected to the upper part; a tensioning device connected to the upper part; wherein the upper and lower parts (12, 14) are secured to one another at corresponding wing portions (58, 60) thereof whereat the upper and lower parts (12, 14) pivot; at least one cable engaging between the upper and lower parts (12, 14) and arranged to be shortened or lengthened for height adjustment relative to the upper and lower parts (12, 14) by the tensioning device to move the lower part relative to the upper part; wherein the height adjustment of the upper part relative to the lower part is configured to maintain the connection of the mandibular support and the posterior component to the anterior component, without changing the anatomical contours of both the mandibular support and posterior component; wherein the cervical collar further comprises: side adjustment connections connecting the mandibular support to the upper part and defining a female component arranged at an oblique angle relative to the vertical centerline (A-A) to enable adjustment of the mandibular supprt relative to the anterior component; and a side height mechanism which secures the wing portions (58, 60) to one another and permits height adjustment of the wing portions (58, 60) relative to one another and including a female component arranged parallel to the vertical centerline (A-A). side adjustment connections connecting the mandibular support to the upper part and defining a female component arranged at an oblique angle relative to the vertical centerline (A-A) to enable adjustment of the mandibular supprt relative to the anterior component; and a side height mechanism which secures the wing portions (58, 60) to one another and permits height adjustment of the wing portions (58, 60) relative to one another and including a female component arranged parallel to the vertical centerline (A-A).
