Since 2005, we’ve inserted percutaneous cages for lumbar arthrodesis in “virgin
spines” and in previously operated spines. Most of the first patients have been
operated on in prone position. In the case of treating one disc by using an arthrodesis
and one hernia on the level above on the same side in lateral position, we began to
carry out the arthrodesis on only one side. Seeing that the results on virgin spines
were encouraging, 29 good primary results with a mean follow-up of 2 years on 39
patients, we wanted to simplify the technique by making a lateral approach. In the
case of two patients we put in two cages on the same side at every level, on L2L3
twice and L3L4 once in the middle of the intervertebral space. In the cases of three
patients, we made a unilateral approach on L4L5 and put in two cages for two
patients and one cage for the last patient. For one other patient, we put in two cages
in L5S1. The immediate results were good. We can’t exactly explain why we can put
in two cages for some patients and only one for others, particularly on the L4L5 level.
Could this be due to the width of the Kambin triangle or to the number and the
position of anastomosis between the exiting root and the white or grey ramus
communicans which carries the nociceptive fibers? We will show each case in details
and discuss the future of this technique.
