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. 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.Aims
Patients and Methods
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. 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.Introduction
