Femur flexion is measured as the angle between the femoral axis and the plumb line (d). Pelvis compensation angle: PTA. Pelvic tilt is measured as usual: line between center femoral head to mid part of S1 plateau and vertical line. If PT between 15 and 25: add 5°. If PT superior 25° add 10° 35 a b C7TA PT c d FOA balance. Interpedicular osteotomy often called Smith-Peterson Osteotomy implies resection of the laminae, the facets, and ligamentum flavum. This creates a 1-cm gap that is closed down by compression of the screws to shorten the posterior column and provides a 8°–10° correction per level .
Damage to these muscles and bony connections can lead to persistent axial pain, cervical malalignment, and spinal instability [1, 7, 8, 12, 25]. Other investigators in trying to preserve the integrity of the spinal column and prevent the atrophy of these muscles reattach the extensor musculature  or preserve the attachments of the semispinalis cervicis and multifidus muscles . All of these steps extend the inherently time-consuming surgery with additional risks. To follow the principle of less invasiveness and the simplest preservation of attachments of musculatures, the split laminotomy technique (Fig.
