Objective One of the unexplained, but well known, characteristics of AIS is that girls are far more often affected than boys and the initiation and progression of the deformity normally occurs around the adolescent growth spurt. From previous studies it can be inferred that, due to biomechanical forces that act on posteriorly inclined spinal segments, certain sagittal spinal profiles are more p...

Adult spinal deformity (ASD) is one of the most challenging spinal disorders associated with broad range of clinical and radiological presentation. Correct selection of fusion levels in surgical planning for the management of adult spinal deformity is a complex task. Several classification systems and algorithms exist to assist surgeons in determining the appropriate levels to be instrumented. ...

vertebral anomalies may also distort the normal regional or global spinal alignment and necessitate some therapeutic interventions. hemiepiphysiodesis is a traditional procedure usually described for these young patients but in more severe cases some type of osteotomy seems to be necessary. in this technical note, we describe a 5-year-old boy with failed previous hemiepiphysiodesis surgery, who...

STUDY DESIGN Prospective case series. PURPOSE To examine the clinical efficacy of mini-open anterior retroperitoneal lumbar interbody fusion: oblique lateral interbody fusion (OLIF) for degenerated lumbar spinal kyphoscoliosis. OVERVIEW OF LITERATURE The existing surgical procedures for the treatment of spinal kyphotic deformity, including Smith-Petersen osteotomy, pedicle subtraction osteo...

BACKGROUND Improved understanding of rod fracture (RF) in adult spinal deformity could be valuable for implant design, surgical planning, and patient counseling. OBJECTIVE To evaluate symptomatic RF after posterior instrumented fusion for adult spinal deformity. METHODS A multicenter, retrospective review of RF in adult spinal deformity was performed. Inclusion criteria were spinal deformit...

The effects of treatment of scoliosis in neurofibromatosis type 1 are less satisfactory than other scoliotic types due to the particular pathogenesis and clinical characteristics. Surgical treatment usually included 360 degrees fusion with instrumentation, but optimal strategies are different according to the degree of deformity. High incidence of pseudarthrosis, extensive bleeding and curve pr...

The progression of post-tubercular kyphosis in 61 children who received ambulatory chemotherapy was studied prospectively. The angles of deformity and kyphosis were measured for each patient at diagnosis, 3, 6, 9, 12 and 18 months later and every year thereafter for 15 years. During the course of the disease signs of instability appeared on the radiographs of some of the children. These were di...

INTRODUCTION Intraoperative neuromonitoring (IONM) has become a standard of care in spinal deformity surgeries to minimize the incidence of new onset neurological deficit. Stagnara wake up test and ankle clonus test are the oldest techniques described for spinal cord monitoring, but they cannot be solely relied upon as a neuromonitoring modality. Somatosensory evoked potentials monitor only dor...

OBJECTIVES This study aimed to investigate the long-term risk of stroke in adult patients with spinal deformity. Specifically, the study addressed the possible protective effect of surgery for spinal deformity against stroke. METHODS Using the National Health Insurance Research Database (NHIRD), a monopolistic national database in Taiwan, this retrospective cohort study analyzed the incidence...
