Analysis of Corrections of Anterior Imbalances by Posterior Instrumentation and Osteotomies

Several deformities of the spine exist such as the anterior imbalance. These deformities can generate functional discomfort and limit the patient's quality of life.

In the event of severe trunk imbalance and progression of the deformity, operative correction of the spinal deformity by instrumentation and posterior arthrodesis may be indicated.

Surgical techniques and instrumentation have evolved over the past 5 years. These changes in surgical strategies have a potential impact on the patient's quality of life and the correction results in the medium and long term.

the aim of the study is to analyze the surgical corrections obtained by transpedicular osteotomy and radiological changes over time with classic 2-rod techniques versus modern 4-rod instrumentation techniques
