Surgical treatment of thoraco-lumbar kyphosis (TLK) associated with low pelvic incidence

Abstract: It seems that keeping the physiological morphology is the treatment of choice. For patients with degenerative scoliosis, reducing the kyphosis could work. We do not recommend to increase the lordosis and obtain a type 3 morphology with an anteverted pelvis because of the risk of PJK and poor functional results.

“…Roughly, a preoperative flat back (type 2) has to stay flat. On the other hand, a pre-existing thoracic kyphosis is better to be reduced in type 1, extending the kyphosis in thoraco-lumbar area as was shown by Scemama et al [20]. In any case, increasing lordosis in length and angle and thus turning the spinal shape into an anteverted type 3 is a bad option and results in high rates of PJK [20,21].…”

“…In summary, the PI value of the initial shape is poorly affected by the degeneration with small balance compensation and thus maintaining the shape is quite easy and always a good option. Type 1 remains problematic for the majority of spine surgeons because reducing the thoracolumbar kyphosis is a common belief that generally leads to complications by inducing an anteverted type 3 that is always a bad option [20]. In the cases where there are compensatory mechanisms, the initial shape has therefore changed.…”

“…As it is a unique value for each patient, it allows determination of the type of sagittal profile according to Roussouly, making it possible, in cases where it is altered by degenerative pathology, to identify the ‘theoretical sagittal shape’ of the patient, guiding where and how much lordosis is necessary to restore with surgery in order to match this theoretical form, 43 which could lead to better functional results and fewer mechanical complications. 11 , 21 , 44 – 47 As Roussouly states, ‘in case of pathology, the PI is the only signature we have to determine the original shape of the spine and restore the balance of the patient’. 21 …”

“…As a result, the Roussouly classification has become one of the most widely used classification systems since 2005, when it was first reported. Many studies have proven the effects of the classification system on surgical decisions and outcomes [9,10,11] . In addition, studies have assessed the correlation between the morbidity of spine disorders and different Roussouly types.…”
