Abstract
There are many treatment options available for treatment of rigid adolescent idiopathic cases, these options could be summarized, with regard to approach, into combined anteroposterior and posterior only approach.
Combined anteroposterior entails opening of the thorax to access the spine anteriorly while posterior only approach entails approaching the spine posteriorly without opening the thorax.
The major disadvantages of combined anterior release and posterior instrumentation procedures are: Increase in surgery time, increase in cost of surgery, increase of blood loss and alterations of pulmonary functions, as a consequence, there is a rising tendency to correct spinal deformity, even the most severe ones, by means of a single posterior technique avoiding the morbidity associated with anterior approach.
The aim of this study is to evaluate posterior only correction of adolescent idiopathic scoliosis as regards safety, efficacy and limitations.
14 AIS patients were included in this retrospective and prospective study, all of them underwent single stage posterior correction of their deformities.
Inclusion criteria were; AIS >50 degrees, age between 10 to 30, and flexibility index ˂50%.
Every patient in this study was subjected to thorough preoperative clinical and radiological assessment, and followed for one year after correction that was done via posterior approach by radical posterior release, pedicle screw instrumentation and, in most of cases, neuromonitorization.
The mean age of our patients was 14.62 ys, mean preoperative Cobb was 85.75 and flexibility index was 12%.
66% correction was obtained to a mean postoperative Cobb 28.75 degrees with 5 % loss of correction over 1 year follow up.
Concerning complications, one patient developed permanent paraplegia (neurological complications 7.14%), one patient had superficial infection (infection 7.14%), 2 patients had cosmetic complications (2 shoulder imbalance) (cosmetic complications 14.29%), and one patient had temporary respiratory support (respiratory complications 7.14%).
The results of this study were gathered together and compared to matched literature.
