A meta analysis of lumbar spinal fusion surgery using bone morphogenetic proteins and autologous iliac crest bone graft.

ABSTRACT:

Background

Bone morphogenetic protein (BMPs) as a substitute for iliac crest bone graft (ICBG) has been increasingly widely used in lumbar fusion. The purpose of this study is to systematically compare the effectiveness and safety of fusion with BMPs for the treatment of lumbar disease.

Methods

Cochrane review methods were used to analyze all relevant randomized controlled trials (RCTs) published up to nov 2013.

Results

19 RCTs (1,852 patients) met the inclusion criteria. BMPs group significantly increased fusion rate (RR: 1.13; 95% CI 1.05-1.23, P = 0.001), while there was no statistical difference in overall success of clinical outcomes (RR: 1.04; 95% CI 0.95-1.13, P = 0.38) and complications (RR: 0.96; 95% CI 0.85-1.09, p = 0.54). A significant reduction of the reoperation rate was found in BMPs group (RR: 0.57; 95% CI 0.42-0.77, p = 0.0002). Significant difference was found in the operating time (MD-0.32; 95% CI-0.55, -0.08; P = 0.009), but no significant difference was found in the blood loss, the hospital stay, patient satisfaction, and work status.

Conclusion

Compared with ICBG, BMPs in lumbar fusion can increase the fusion rate, while reduce the reoperation rate and operating time. However, it doesn't increase the complication rate, the amount of blood loss and hospital stay. No significant difference was found in the overall success of clinical outcome of the two groups.

Project description:Study Design?Systematic review. Clinical Questions?(1) Is autologous local bone (LB) graft as safe and effective as iliac crest bone graft (ICBG) in lumbar spine fusion? (2) In lumbar fusion using ICBG, does a single-incision midline approach reduce postoperative iliac crest pain compared with a two-incision traditional approach? Methods?Electronic databases and reference lists of key articles were searched up to October 2014 to identify studies reporting the comparative efficacy and safety of ICBG versus LB graft or comparing ICBG harvest site for use in lumbar spine surgery. Studies including allograft, synthetic bone, or growth factors in addition to ICBG and those with less than 80% of patients with degenerative disease in the lumbar spine were excluded. Two independent reviewers assessed the level of the evidence quality using the Grades of Recommendation Assessment, Development and Evaluation criteria, and disagreements were resolved by consensus. Results?Seven studies were identified as using ICBG fusion for degenerative disease in the lumbar spine. There were no differences in the fusion, leg pain, low back pain, or functional outcomes between patients receiving LB versus ICBG. There was a higher incidence of donor site pain and sensory loss in patients receiving ICBG, with no donor site complications attributed to LB. Compared with patients with the graft harvested through the two-incision traditional approach, patients with the graft harvested through the single-incision midline approach had lower mean pain scores over the iliac crest, with a higher proportion reporting no iliac crest tenderness. In patients with ICBG harvested through the single-incision midline approach on either the right or the left side of the ilium, only 36% of the patients were able to correctly identify the side when asked whether they knew which iliac crest was harvested. Only 19% of the patients with ICBG harvested through the single-incision midline approach on either the right or the left side of the ilium reported pain that was concordant with the side that was actually harvested. Conclusions?LB is as safe and efficacious as ICBG for instrumented fusion in the lumbar spine to treat degenerative disease. When ICBG is used, graft harvest through the single-incision midline approach reduces postoperative iliac crest pain compared with a two-incision approach.

Project description:BackgroundAutogenous Iliac Crest Bone Graft (ICBG) has been the "gold standard" for spinal fusion. However, bone graft harvest may lead to complications, such as chronic pain, numbness, and poor cosmesis. The long-term impact of these complications on patient function and well-being has not been established but is critical in determining the value of expensive bone graft substitutes such as recombinant bone morphogenic protein. We thus aimed to investigate the long-term complications of ICBG. Our second aim was to evaluate the psychometric properties of a new measure of ICBG morbidity that would be useful for appropriately gauging spinal surgery outcomes.MethodsProspective study of patients undergoing spinal fusion surgery with autologous ICBG. The SF-36v2, Oswestry Disability Index, and a new 14-item follow-up questionnaire addressing persistent pain, functional limitation, and cosmesis were administered with an 83% response rate. Multiple regression analyses examined the independent effect of ICBG complications on physical and mental health and disability.ResultsThe study population included 170 patients with a mean age of 51.1 years (SD = 12.2) and balanced gender (48% male). Lumbar fusion patients predominated (lumbar = 148; cervical n = 22). At 3.5 years mean follow-up, 5% of patients reported being bothered by harvest site scar appearance, 24% reported harvest site numbness, and 13% reported the numbness as bothersome. Harvest site pain resulted in difficulty with household chores (19%), recreational activity (18%), walking (16%), sexual activity (16%), work activity (10%), and irritation from clothing (9%). Multivariate regression analyses revealed that persistent ICBG complications 3.5 years post-surgery were associated with significantly worse disability and showed a trend association with worse physical health, after adjusting for age, workers' compensation status, surgical site pain, and arm or leg pain. There was no association between ICBG complications and mental health in the multivariate model.ConclusionChronic ICBG harvest site pain and discomfort is reported by a significant percentage of patients undergoing this procedure more than three years following surgery, and these complications are associated with worse patient-reported disability. Future studies should consider employing a control group that does not include autologous bone graft harvest, e.g., a group utilizing rhBMP, to determine whether eliminating harvest-site morbidity does indeed lead to observable improvement in clinical outcome sufficient to justify the increased cost of bone graft substitutes.
