Anatomic and clinial study of paraspinal intermuscular space in the thoracolumbar spine
摘要
Abstract
Objective To evaluate the anatomy of paraspinal intermuscular space ( Wiltse space ) in the thoraco-lumbar spine, in order to provide a morphological basis for the minimally invasive pedicle screw fixation surgery. Methods The Wiltse space in thoracolumbar spine and its adjacent structures were observed in 9 (18 sides) cada-vers with regional anatomy. Another 4 (8 sides) cadavers were selected to simulate pedicle screw fixation. Results The surface of Wiltse space was covered by the erector spinae aponeurosis, which was constituted by the tendons of longissimus pars thoracis. After the potential space was separated bluntly between the thoracic semispinalis tendons and the first medial tendon of longissimus (83%, 15 sides) , or between the first and the second tendon of longissi-mus additionally (17%, 3 sides) . The Wiltse space in all the thoracolumbar spine was exposed clearly. Through the Wiltse space, the multifidus, T11-T12 transverse process, L1-L2 articular process were exposed. After the accurate entry points of pedicle screw were shown, the pedicle screw fixation was simulated, and the pedicle screws were inserted into pedicle and vertebral body successfully. The location of the pedicle screws were assured by posto-peration CT, and the multifidus remained intact. Conclusion In-depth understanding of the anatomy of Wiltse space in the thoracolumbar spine will contribute to the improvement of the minimally invasive pedicle screw fixation in this area.关键词
