Aims

Minimally invasive transforaminal lumbar interbody fusion (MITLIF) has been well validated in overweight and obese patients who are consequently subject to a higher radiation exposure. This prospective multicentre study aimed to investigate the efficacy of a novel lumbar localisation system for MITLIF in overweight patients.

Patients and Methods

The initial study group consisted of 175 patients. After excluding 49 patients for various reasons, 126 patients were divided into two groups. Those in Group A were treated using the localisation system while those in Group B were treated by conventional means. The primary outcomes were the effective radiation dosage to the surgeon and the exposure time.

Introduction

The cause of adolescent idiopathic scoliosis (AIS) is still not known. Although several candidate gene studies and linkage analyses have been done, no causal relationship has yet been established. To our knowledge, we report the first case-control based genome-wide association study (GWAS) for this trait.

Methods

The study was undertaken in a set of 196 cases with a specific AIS phenotype (based on Lenke's classification) in southern China, and in 401 controls without radiological evidence of scoliosis.
