What is the treatment of odontoid fracture of axis?

summary

Odontoid process fracture of axis is a serious injury involving the stability of atlantoaxial region, accounting for about 10% of cervical spine injury. Because of its special anatomical structure, the incidence of nonunion is also high. The existence of unstable factors may lead to acute delayed cervical spinal cord compression and life-threatening.

What is the treatment of odontoid fracture of axis?

The operation can be performed through oral cavity or neck. For fresh fractures, long and thin screws (1 or 2 screws) were preferred. For old fracture nonunion, atlantoaxial fusion is feasible, either anterior or posterior, or through lateral anterior approach.

The weight should be 1.5-2kg. Don't be overweight to prevent delayed healing. After 1-2 weeks of traction, the alignment of fracture line was observed by bedside photography. After continuous traction for 3-6 weeks, the head neck chest plaster or halo device can be changed, and then gradually get up and exercise.

Odontoid process nonunion is not uncommon in clinic, and it is the most common complication of odontoid process fracture. Odontoid process nonunion is especially common in fracture line. Type II fracture through the waist of odontoid process is mainly due to dislocation of this type of fracture, because the traction of the apical ligament of odontoid process and the pterygoid ligament can separate the fracture, and the pushing of the posterior transverse ligament can also make it shift.

More sunlight: sunlight can promote the synthesis of vitamin D, and calcium metabolism depends on the role of vitamin D; Ultraviolet rays in the sun can promote the formation and absorption of calcium in the body, maintain the normal calcium and phosphorus metabolism, increase the calcium in the bone and improve the hardness of the bone.
