Application value of three-dimensional printing personalized navigation template in posterior lower cervical pedicle screw placement
摘要
Abstract
BACKGROUND: Posterior pedicle screw fixation of lower cervical spine has many advantages. However, because of the special anatomy of pedicle, the technical requirements of nailing placement are high and it is also a challenge to surgeons. The application of three-dimensional (3D) printing technology can help to complete screw placement, and has certain advantages. OBJECTIVE: To introduce the method of 3D printing personalized navigation template assisted posterior lower cervical pedicle screw fixation and evaluate its clinical application value. METHODS: Totally 20 patients with lower cervical spine pedicle screw internal fixation who were treated from June 2015 to December 2016 in Affiliated Hospital of Yan'an University were retrospectively analyzed. Before the surgery, the patient's lower cervical spine CT data was introduced into the relevant software and the 3D printing personalized navigation template assisted nailing pedicle screw was designed. The number of screws inserted was recorded. After the operation, CT scan was used to calculate the accuracy rate of screw placement. Preoperative and postoperative cervical spine Visual Analogue Scale score and spinal function score of Japanese Orthopedic Association were used to evaluate the clinical effect of cervical nerve. RESULTS AND CONCLUSION: (1) All patients were followed up for 3 months postoperatively. (2) 3D printing personalized navigation template assisted 132 pedicle screws. The precise insertion rate was 94.7%. Among them, 125 screws were at grade 0 (94.7%, 125/132), 3 screws grade 1 (2.3%, 3/132), 4 screws grade 2 (3.0%, 4/132), no screw grade 3. (3) At postoperative 1 and 3 months, the neck shoulder Visual Analogue Scale score and spinal function score of Japanese Orthopedic Association of the patients were significantly improved (P < 0.05), but there was no significant difference (P > 0.05), compared with those at preoperative. (4) In summary, 3D printing personalized navigation template assisted cervical pedicle screw placement had the high insertion rate and satisfactory clinical efficacy.关键词
