MATERIAL and METHODS: The results of 21 patients with cervical PLK treated using the pedicle screw method between 2015 and 2018 were retrospectively examined. Patient data included demographic information and indications for surgery. Furthermore, the following criteria were calculated for each patient: cervical sagittal vertical axis (cSVA), C2-7 cervical lordosis (CL) parameters, modified Japanese Orthopaedic Association (mJOA) score, Neck Disability Index (NDI) score and visual analogue scale score, and these were evaluated preoperatively and postoperatively statistically.

RESULTS: A total of 21 patients with PLK were evaluated. In terms of radiographic parameters, postoperative cSVA was significantly lower than the preoperative cSVA, and postoperative CL was significantly higher than the preoperative CL (p<0.001, p<0.001, respectively). Postoperative mJOA scores were significantly higher than the preoperative scores (p < 0.001). Both postoperative NDI and VAS scores were significantly lower than the preoperative scores (p<0.001, p<0.001 respectively).

CONCLUSION: Pedicle screw fixation was found to be an effective treatment for cervical PLK. Although this technique is not preferred by many spine surgeons because of its high complication rate, it has a positive effect on the quality of life scores and provides optimal correction.
