Optimising deformity correction: a retrospective comparative analysis of two techniques in high magnitude curves in adolescent idiopathic scoliosis.

Study Design: A retrospective comparative study.

Purpose: To validate the hypothesis that a combination of multilevel Ponte osteotomy (PO) with intraoperative traction (IOT) results in a better correction than IOT alone in high-magnitude curves in adolescent idiopathic scoliosis (AIS) and does not possess an attributable risk of neurological injury.

Overview Of Literature: On a comprehensive review of the literature, the choice of technique adopted for curves between 65° and 100° remains controversial with no major consensus favoring one technique over the other.

Finite Element Analysis Comparing the Biomechanical Parameters in Multilevel Posterior Cervical Instrumentation Model Involving Lateral Mass Screw versus Transpedicular Screw Fixation at the C7 Vertebra.

Study Design: Basic research.

Purpose: This finite element (FE) analysis (FEA) aimed to compare the biomechanical parameters in multilevel posterior cervical fixation with the C7 vertebra instrumented by two techniques: lateral mass screw (LMS) vs. transpedicular screw (TPS).

"Insert flipping technique:" An effective way of restoring segmental lordosis and disc height with tall bullet cages.

Study Design: The study design was a retrospective study.

Objective: The objectives of the present study are dual; to describe a simple and effective way of restoring intervertebral disc (IVD) height by the "Insert Flip Technique" of cage insertion and to demonstrate effective restoration of IVD height and segmental lordosis (SL) and their influence on the functional outcome postoperatively.

Methods: IVD height and SL were recorded pre- and postoperatively.
