The study involved 69 consecutive OLLIF surgeries on 128 levels as well as 55 consecutive open transformational lumbar interbody fusions on 125 levels.
Here are five takeaways:
1. The study revealed a mean surgery time of 69 minutes for a single-level OLLIF.
2. The researchers noted open TLIF surgery took almost twice as long (135 minutes) to perform as single-level OLLIF.
3. A single-level OLLIF also saw a mean blood loss of 29 ml, representing an 80 percent decrease from mean open TLIF blood loss.
4. Open TLIF involved a mean blood loss of 355 ml.
5. Researchers concluded OLLIF decreases surgery times and eliminates difficulties associated with open fusions. Therefore, OLLIF presents a safer and less-demanding surgery than open or minimally invasive TLIF.
