Minimally invasive surgery
Presently, lumbar spondylolisthesis did not have the indication of direct repair surgery because of the difficulty to reduce the slippage. In this report, we presented a case and described a minimally invasive direct repair surgery to reduce and repair the pars interarticularis defects of lumbar spondylolisthesis. First, curettage and removal of the synovium of the pars interarticularis and decompression of nerve root are conducted. Next, cancellous bone is harvested from the iliac crest. And then the Percutaneous Pedicle Screws are inserted bilaterally. A rod is bended and placed just caudal to the spinous process. We can make reposition of slipped vertebra and stabilize the loose lamina more firmly using a reduction tool and a rod pusher. Finally, bone grafts are implanted onto the pars defects. The Smiley face rod method is very useful to reduce the slippage and repair the pars defects in the lumbar spondylolisthesis especially in adolescent athletes.
