For the spinal tumor at fifth lumbar vertebra, the difficulty of approach was more encountered than other thoracic and lumbar vertebra. The narrow window of the fifth lumbar vertebra was made by the surrounding common iliac vessels and iliac crest. The current paper shows the useful method for lateral access of L5 vertebra using the posterior approach by iliac crest cut and transposition with erector spinae muscles.
