Summary

The surgical management of spinal deformities especially in adults is complex. The conventional surgical treatment of these deformations is a scope arthrodesis of the spine. The quality of the result depends on many variables such as the choice of the vertebrae to fuse, location and the number of implants, the type of material used or the type of correction maneuver used.

All these variables affect the surgical outcome and may be involved as a modifiable risk factor for possible postoperative complications. The study proposes to focus on the junctional kyphosis postoperative proximal (CJP or Proximal Junctional Kyphosis: PJK). Their prevalence in adults ranges from 20% to 43% depending on the series.

The radiographic definition of CJP's kyphosis with an angle\> 10 ° measured from the lower plate of the proximal instrumented vertebra to the upper plate of the adjacent vertebra proximal not instrumented; this measure is being compared to the pre operative data.

Either the CJP are asymptomatic and do not require revision surgery either they are and thereby generate a revision surgery.

Several factors may potentially influence the development of the CJP. Among them, age, preoperative comorbidities, obesity, osteoporosis, lesions of the posterior elements, hybrid instrumentation, correction forces applied during surgery, sagittal balance pre and post operative degeneration joint capsules, etc. There are few studies on the identification and analysis of these risk factors; literature gives only single-center studies on small samples with a single surgical procedure. Review articles describe the incidence and risk factors of the CJP. However, the pathophysiological mechanisms of the CJP are still controversial to this day.

The aim of this study is to determine the incidence of occurrence of postoperative kyphosis proximal junctional and identify risk factors for developing this major complication of a multicenter population of scoliosis operated an extensive fusion.
