The most common procedure for surgical treatment of lumbar spondylolysis is intertransverse processes spinal arthrodesis with instrumentation. However, this procedure is associated with significant morbidity on long-term follow up. Direct repair of spondylolysis is an alternative method for preservation of motion segment and anatomic continuity in young adults with multiple level spondylolysis. From 1992 through 1998, six soldiers with a diagnosis of multiple level spondylolysis who complained of persistent low back pain were treated in our hospital. Spondylolysis involved two levels in five cases and three levels in one case. All patients underwent serial roentgenography of the lumbar spine and a staged pars interarticularis infiltration test with bupivacain 0.5%. Five patients underwent direct repair of the pars interarticularis defects with hook screws, translaminar screws, and bone graft, while one patient received conservative treatment. All surgically treated patients had either good or excellent results at a mean of 34.4 months follow-up. One patient who was treated nonsurgically still complained of sport restriction at 16 months follow-up. Direct repair of multiple pars interarticularis defects after a positive staged pars infiltration test can restore anatomic stability, relieve back pain, and preserve a greater range of motion of the lumbar spine in young patients with intact disc height.
