Objective To review the latest comparative research of minimally invasive transforaminal lumbar interbody fusion (TLIF) and traditional open approach. Methods The domestic and foreign literature concerning the comparative research of minimally invasive TLIF and traditional open TLIF was reviewed, then intraoperative indicators, length of hospitalization, effectiveness, complication, fusion rate, and the effect on paraspinal muscles were analyzed respectively. Results Minimally invasive TLIF has less blood loss and shorter length of hospitalization, but with longer operation and fluoroscopic time. Minimally invasive surgery has the same high fusion rate as open surgery, however, its effectiveness is not superior to open surgery, and complication rate is relatively higher. In the aspect of the effect on paraspinal muscles, in creatine kinase, multifidus cross-sectional area, and atrophy grading, minimally invasive surgery has no significant reduced damage on paraspinal muscles. Conclusion Minimally invasive TLIF is not significantly superior to open TLIF, and it does not reduce the paraspinal muscles injury. But prospective double-blind randomized control trials are still needed for further study.
Objective To compare and research the process of woundhealing in occlusive moist environment and dry environment on the skin donor site. Methods The wound healing of adult skin donor site was studied by clinical observation, histological and electromicroscopical examinations on the operative day and the 1st, 2nd, 3rd, 4th, 7th days postoperatively, each skin donor site was divided into two parts: occlusive environment and dry environment. Results The wounds of occlusive moist environment healed faster than those of dry environment; thefibroblasts were more active and activated earlier, revascularization and re-epithelialization happened earlier and more quickly. Conclusion In occlusive environment, more active fibroblasts can accelerate granulation growth; quicker regenerative capillaries bring more nourishment; quicker re-epithelialization accelerates the wound healing.
