OBJECTIVE: to justify the modified Buck's technique of pars reconstruction as an effective method to spondylolysis and low grade spondylolisthesis treatment. METHODS: eight patients with ages 11 to 34 years were retrospectively evaluated from October 2004 to may 2008. They were operated with Buck´s technique using titanium canulated screws. Immobilization wasn't used in any patient in post-operative period. All patients were studied with magnetic resonance imaging. All patients were assessed in post-operative period with Henderson's criteria of functional capacity. RESULTS: seven patients were assessed as excellent. They didn´t complain pain and were able to return to former occupation and sportive activities. One patient presented temporary paresthesia and leg weakness, and one patient bilateral pseudoarthrosis that cursed with good grade functional capacity. All patients were satisfied with treatment. CONCLUSION: the isthmic reconstruction using titanium screws allowed excellent results allied with stable biomechanics, minimal injury to back muscles, preservation of anatomy and segmental mobility, and better operated spinal imaging.
