Abstract:
BACKGROUND: Bilateral pedicle screw fixation combined with intervertebral decompression and fusion is a classic surgical approach in treatment of lumbar degenerative diseases, but it can cause ligament and other soft tissue damage of lumbar spine and degeneration of the adjacent segments. While translaminar facet screw fixation has its unique advantages.OBJECTIVE: To compare the clinical efficacy of unilateral pedicle screw fixation combined with translaminar facet screw fixation and bilateral pedicle screw fixation for lower lumbar degenerative diseases.METHODS: Forty-six patients with single-level lower lumbar degenerative disease were enrolled, and were then treated with bilateral pedicle screw fixation combined with intervertebral fusion (group A, n=24) or unilateral pedicle screw along with translaminar facet screw fixation and intervertebral fusion (group B, n=22). Afterwards, the clinical indexes and efficacy were compared between two groups.RESULTS AND CONCLUSION: (1) All operations were performed successfully. The length of incision, operation time,intraoperative blood loss, postoperative drainage volume and cost of hospitalization in the group B were significantly superior to those in the group A (P < 0.05). (2) There was no significant difference in the rate of fusion between two groups (P > 0.05). (3) The visual analogue scale and Japanese Orthopaedic Association scores in both groups at 1 week,3, 6, 12 and 24 months postoperatively were significantly improved compared with baseline (P < 0.05), but the scores had no significant differences between two groups (P > 0.05). (4) To conclude, unilateral pedicle screw fixation combined with translaminar facet screw fixation and bilateral pedicle screw fixation both exhibit satisfactory treatment outcomes,while the former holds little trauma, good stability, high fusion rate and less cost, which is a better choice for lower lumbar degenerative diseases.
