Stevenson et al. (2014) describe a cadaver with a severe case of congenital scoliosis. The erector spinae muscles were severely atrophied on the left side and many parts were replaced by tendinous insertions. Erector spinae on the right side was comprised of typical fleshy muscle fibers but the tendons of iliocostalis inserted in a radial manner due to the abnormal thoracolumbar curvature (Stevenson et al. 2014).
The Bladder (BL)

Erector spinae muscles (transversospinalis, longissimus thoracis, and iliocostalis thoracis muscles): Acting unilaterally, the erector spinae bend the vertebral column in a lateral direction; acting bilaterally, they extend the head and vertebral column.

Identify and separate the three longitudinally oriented columns of the erector spinae muscle: the spinalis, longissimus and iliocostalis. Then, to expose the deeper musculature, remove a block of the erector spinae muscles several inches long from the lower thoracic and upper lumbar region and attempt to identify the transversospinalis musculature. The transversospinalis muscles include the semispinalis, multifidus and rotatores.

ESPB was conducted under perfect aseptic circumstances after induction of anaesthesia and 15 min before skin incision using a 100-mm 21 G needle guided by a US probe (linear) with a frequency of 6–13 MHz in either group (Siemens, CA, 94043, USA). Chin et al. demonstrated that ESPB was carried out unilaterally, on the same side of surgery, with the patients in a lateral decubitus position [14]. The block was performed using a sagittal approach, and the probe was positioned 2–3 cm laterally to the spine at the T5 level of the spine. As the transverse processes and the muscle (erector spinae) were located, the needle was advanced deeply into the muscle. Group B served as the control group, receiving 20 mL of 0.25% bupivacaine +2 mL of saline whereas group BC received the study solution (20 mL of bupivacaine 0.25% plus 50 IU of calcitonin in 2 mL of saline). The block performance between the transverse process and the erector spinae muscle were given to both groups, and LA was distributed both cranially and caudally.

From the results of the left/right erector spinae muscle in Figure 4, we can clearly see that the tilt of the tractor causes asymmetric activation of the driver's erector spinae. From the data obtained from the simulation, with the increase of tilt angle of the tractor, the difference value of the muscle activity of the driver's left and right erector spinae muscles is increasing. The difference between the muscle activity of the driver's left and right erector spinae muscle at 5° and 10° of tractor tilt was at 1.9%, and the difference between the maximum muscle activity of the driver's left and right erector spinae muscle at 15° of tractor tilt reached 3.29%. In both simulated and experimental data, we observed that the growth trend of the erector spinae muscles were essentially the same for both methods. The increasing tilt angle of the tractor to the left leads to an increase in muscle activity of the erector spinae muscles, and the increase in muscle activity of the left erector spinae muscle is greater than that of the right erector spinae muscle.

The sitting domain of the GMFM declined with decreased thoracic erector spinae muscle thickness and declined spinal alignment. The lying and rolling domain in the GMFM also showed a similar association in the present study. The decline in the sitting domain was associated with decreased thoracic erector spinae muscle thickness because the muscle strength of thoracic erector spinae muscle, which contributes to trunk extension movement and postural control of the trunk on the sagittal or coronal planes during forward or lateral reaching motions of the upper extremities, is required to maintain a seated posture in children and adults with CP. A previous study demonstrated a lower thoracic erector spinae muscle thickness in adults with CP who can not sit independently compared to that in those who can sit independently.5 The finding of the present study of the association of reduced sitting ability with decreased thoracic erector spinae muscle thickness was consistent with that of the previous study, although parameter of assessment in the present study (GMFM) differed from that in the previous study (propriety of independent sitting). Furthermore, kyphosis or scoliosis contributed to the association between reduced sitting and declined spinal alignment, which leads to shifts in the center of gravity in the sagittal or coronal planes, making sitting unstable in children and adults with CP.
