A study presented at the Society for Minimally Invasive Spine Surgery Annual Forum 2016 compared early and late reoperation rates for circumferential minimally invasive spine surgery and hybrid surgeries.
The study authors examined 133 patients from a database; 65 patients underwent the hybrid procedure and 68 patients underwent circumferential minimally invasive spine surgery. The study authors found:
1. Among the hybrid procedure group, the junctional failure was the most common reason for reoperation, accounting for 15.4 percent of the reoperations.
2. For the patients who underwent circumferential minimally invasive spine surgery, the most common reason for reoperation was fixation failure.
3. The PJF rate was higher than the DJF rate for patients who underwent the hybrid procedure.
4. There wasn't a difference in PJF and DJF rates between the hybrid procedure patients and the circumferential minimally invasive surgery patients.
5. Reoperations more than 30 days after surgery were more common in both groups than reoperations fewer than 30 days after surgery. Early and late reoperation rates were similar between both groups.
6. The overall reoperation rate for the circumferential minimally invasive spine surgeries was 27.9 percent, compared with 33.8 percent among the hybrid techniques. There was a minimum of two year follow-ups.
