Cervical-thoracic orthotic with cervical collar
View Patent ↗An orthosis comprises a cervical portion that holds a head in place relative to a thoracic portion worn by a wearer. The orthosis has an intermediate portion disposed intermediate the cervical and thoracic portions. The orthosis also has a first adjustment region that provides at least 15° of relative movement between the cervical and intermediate portions, and a second adjustment region that provides at least 15° of relative movement between the thoracic and intermediate portions. First and second adjustment regions allow the orthosis to comfortably accommodate differently proportioned wearers, and each comprises one or more locking devices to prevent undesired movement of the cervical and thoracic portions relative to the intermediate portion.
1. An orthosis comprising:
a cervical portion;
a thoracic portion;
an intermediate portion disposed intermediate the cervical and thoracic portions;
a first splined adjustment region configured to provide at least 15° of relative movement between the cervical and intermediate portions; and
a second splined adjustment region configured to provide at least 15° of relative movement between the intermediate and thoracic portions.
2. The orthosis of claim 1 , wherein at least one of the first and second splined adjustment regions is biased into an open position.
3. The orthosis of claim 1 , wherein the splines are internal.
4. The orthosis of claim 1 , wherein the splines are lateral.
5. The orthosis of claim 1 , wherein the splined adjustment region has a coarseness of between 10-30 positions.
6. The orthosis of claim 1 , wherein at least one of the first and second adjustment regions comprises a pivot.
7. The orthosis of claim 6 , further comprising an adaptor portion disposed between the cervical portion and the intermediate portion, and the pivot is composed of ends of the adaptor portion and the intermediate portion.
8. The orthosis of claim 6 , wherein the first adjustment region removably attaches to the cervical portion using a clip.
9. The orthosis of claim 1 , wherein the first adjustment region achieves the relative movement between the cervical and intermediate portions by bending.
10. The orthosis of claim 1 , wherein at least one of the first and second adjustment regions provides at least 25° of the relative movement between the cervical and intermediate portions and the thoracic and intermediate portions, respectively.
11. The orthosis of claim 6 , wherein the second adjustment region removably attaches to the thoracic portion using a clip.
12. The orthosis of claim 1 , wherein the second adjustment region achieves the relative movement between the cervical and intermediate portions by bending.
13. The orthosis of claim 1 , wherein the intermediate portion has a superior end and an inferior end, and is sufficiently rigid to maintain a fixed angular relationship between the ends within a 10° tolerance.
14. The orthosis of claim 1 , wherein the intermediate portion has a minimum end-to-end length of at least 10 cm.
15. The orthosis of claim 1 , wherein the thoracic portion has a telescoping region.
16. The orthosis of claim 1 , wherein the first adjustment region provides at least 30° of the relative movement between the cervical and intermediate portions, and the second adjustment region provides at least 30° of the relative movement between the thoracic and intermediate portions.
17. A method of coupling a cervical orthotic with a thoracic orthotic on a wearer, comprising
coupling the cervical and thoracic orthotics with first and second pivots to compose a cervico-thoracic orthotic, where each of the first and second pivots comprises a splined adjustment region; and
operating the cervico-thoracic orthotic such that each of the pivots is continuously operable while the cervico-thoracic orthotic is being worn by the wearer.
18. The method of claim 17 , further comprising snap coupling the cervical orthotic with an intermediate piece that includes the first pivot.
19. The method of claim 17 , further comprising providing a telescoping region between the cervical and thoracic orthotics.
20. The method of claim 17 , wherein the step of coupling comprises disposing first and second intermediate pieces between the cervical and thoracic orthotics.
