To analyze the clinical and radiologic outcomes of bilateral uncovertebral joints resection and decompression in treating cervical spondylotic radiculopathy through anterior approach.
From January 2007 to December 2009, the clinical data of 56 patients with cervical spondylotic radiculopathy undergoing sugical treatment were retrospectively analyzed. There were 33 males and 23 females with an average age of (58.83 +/- 8.01) years (ranged 41 to 72). The course was from 5 to 48 months with an average of (14.09 +/- 8.54) months. All patients underwent bilateral uncovertebral joints resection, vertebral canal decompression and fusion through anterior approach. Perioperative, radiologic,nerve functional parameters were analyzed before and after operation. Perioperative parameters included hospital stay days and blood loss volume and operative time; radiologic parameters included vertebral height and lordosis angle and fusion rate; and according to JOA score to evaluate the nerve function.
All patients were followed up from 12 to 30 months with an average of 18.2 months. Hospital stay days, blood loss volume and operative time were (4.42 +/- 0.25) d, (195.51 +/- 23.67) ml and (145.52 +/- 28.29) min, respectively. Preoperative vertebral height was (5.19 +/- 0.03) cm, and postoperative 1 year arrived to (5.37 +/- 0.29) cm, there was no significant difference between preoperative and postoperative (P > 0.05). Lordosis angle increased from preoperative (1.53 +/- 0.03) degrees to (7.78 +/- 0.66) degrees at the 1 year after operation (P<0.01). Fusion rate was 96.5% at the 1 year after operation. JOA score increased from preoperative 8.69 +/- 2.13 to 15.58 +/- 2.45 at the 1 year after operation (P < 0.001). According to standard of JOA scoring, 20 cases were excellent, 28 good, 7 fair and 1 poor.
Uncovertebral joints resection and decompression through anterior cervical approach in treating cervical spondylotic radiculopathy is safe and reliable, which can get satisfactory clinical outcomes. This surgical procedure is suitabl oe for the patients of cervical spondylosis, especially combined canal stenosis and osteophytosis of the uncovertebral joint.
