Lateral Fusion

✓The goal of this study was to establish a much less invasive method for access to the lateral lumbar spine for posterolateral fusion and pedicle screw (PS) placement. The technique was developed through knowledge of the anatomy literature and the author's clinical experience in more than 90 completed cases. The lateral intramuscular planar approach provides a much less invasive access to the lateral aspect of the lumbar spine and sacrum. An invariant intramuscular plane, poorly described in the anatomical literature, is ideal for postero-lateral fusion and/or PS placement from L-3 caudally. The approach requires essentially no resection of the multifidus muscle, or of the pars thoracis of the erector spinae.

Foraminal Height

A cadaveric study was performed to compare the effect of anterior versus posterior distraction instrumentation on lumbar foraminal height and lordosis. Pedicle screws and interbody instrumentation can be used to distract vertebral bodies, thereby increasing foraminal height. BAK interbody cages were inserted anteriorly at L4-L5 and L5-S1 in ten spines. Isola instrumentation was applied posteriorly in six spines at L4, L5, and S1. Both anterior instrumentation and posterior pedicle screw instrumentation provided significant increase in foraminal height with slight decrease in total lumbar lordosis. Foraminal height increased with larger cages at the level in which the cages were first applied, and the addition of cages at the neighboring level had a little effect. However, no statistically significant differences were found with different sizes of cages at the neighboring level. The maximum change in foraminal height occurred with 10 mm of posterior distraction, but a plateau effect was observed over six mm. Distraction of the lumbar spine is effective in increasing foraminal height with relatively small losses of lumbar lordosis. Similar increases were obtained with the anterior and posterior approaches. The surgeon should choose a particular method based on the patient's pathology.
