Schematic images of the center of gravity shift during standing-up motion. (a) Normal center of gravity shift; the hip flexion and spinal kyphotic movement move the center of gravity forward. (b) Center of gravity shift in a patient with post-spinal fusion status and hip contracture. Since hip flexion and spinal kyphotic movement are impossible, the patients should use pendulum-like movements to shift the center of gravity anteriorly. This may contribute to the early onset of proximal junctional failure.

Introduction: In cases with markedly decreased hip function, patients predominantly utilize spine movement while standing up to compensate for the hip malfunction. However, spinal fusion surgeries might lead to the disruption of this compensatory mechanism, resulting in difficulties in walking and standing up as well as proximal junctional failure...

Context 1
... hip flexion [14]. This compensatory mechanism probably became dysfunctional after the long spinopelvic fixation procedure. The patient required a pendulum-like motion of the trunk to shift the center of gravity forward, and the repetitive stress on the spine by this pendulum-like motion might have caused the PJF in the early post-operative period (Fig. 5a, ...

Purpose:
The correction of double thoracic (Lenke 2) curves has been associated with higher rates of postoperative shoulder imbalance that may compromise long-term outcomes following spinal deformity correction. A number of methods have been proposed to mitigate this risk, though no accepted standard measurement exists. The purpose of this study i...
