Abstract:
Objective To compare the fusion effect between lumbar posterolateral fusion (PLF) and posterior lumbar interbody fusion (PLIF) in elderly patients with lumbar spinal stenosis.Methods Data of 313 patients undergoing PLF or PLIF for treatment lumbar degenerative disease in Department of Orthopedics,Beijing Hospital of China Ministry of Health during January 1996 to December 2011 were retrospectively analyzed.Patients were divided into PLF group (n=116 cases) and PLIF group (n=197 cases).Data of fusion rate,operative time,operative blood-loss and complications were analyzed statistically.Results The fusion rate was 84.5％ in PLF group and 98％ in PLIF group.The average operative time was 247.8 min (120-480 min) and 240.6 min (90-600 min) in PLF and PLIF groups respectively.The blood-loss was 1142.9 ml (200 4500 ml) and 927.0 ml (200-2800 ml) in PLF and PLIF groups respectively.Postoperative complications were found in 38 cases in PLF group and in 36 cases in PLIF group.There were significant differences in fusion rate,operative time,operative blood loss,complications between the two groups (all P＜0.05).Conclusions PLIF has better effects on fusion rate and fusion grade than PLF.
