Abstract
INTRODUCTION: Commonly, two stage combined anterior - posterior approaches were performed to treat significant kyphotic deformity, but potentially increase morbidity level. Recently, single - stage posterior approach for anterior column reconstruction have shown sagittal alignment improvement. The objective of this study is to describe a series of kyphotic deformity patients whom were treated using modified lateral extracavitary approach for anterior column reconstruction and posterior instrumentation. METHODS: Data collected from all kyphotic deformity patients whom treated with modified lateral extracavitary approach between 2016 until 2017 and this research work has been reported in line with the PROCESS criteria. In addition this technique could address kyphotic correction. RESULTS: 7 patients were reported, 4 males and 3 females with local and regional kyphotic more than 40 degrees. Procedures performed mostly on the right side to avoid the aorta with approximately 2 cm of the rib distal to the transverse processes. The average estimated blood loss and length of surgery were 1280 ml and 3.9 h. None of the patient had neurological deficit, and all of them have shown kyphotic improvement. CONCLUSION: The modified lateral extracavitary approach for anterior column reconstruction and posterior instrumentation is a viable alternative to the standard combined approach. This approach continues to evolve as instrumentation development and possesses significant advantages.
