Vitamin D deficiency is a common problem in the UK. It is more prevalent in patients with orthopaedic conditions. Previous studies in the literature have shown that vitamin D deficiency is associated with low patient-related outcome scores. To date, no studies have been performed in spinal patients. The aim of this study was to investigate whether there is a relationship between vitamin D status and pre-operative outcome scores in patients with AIS. AIS patients undergoing scoliosis correction between July 2012 and May 2013 at the Royal National Orthopaedic Hospital were investigated. Serum 25-hydroxyvitamin D levels were measured and SRS-22r questionnaires were completed as part of their pre-admission work up.Aim:
Methods:
We propose a simple classification for adolescent idiopathic scoliosis (AIS) based on two components which include the curve type and shoulder level and suggest a treatment algorithm for AIS. Few Classification systems for adolescent idiopathic scoliosis (AIS) have helped in communicating, understanding and selecting a treatment for this condition; however, most of these classifications are complex and include many subtypes, making it difficult for the orthopaedic surgeon to use them in clinical practice. The variable reliability and reproducibility of these studies make recommendations and comparisons between various operative treatments a difficult task. Furthermore, none of these classifications has taken the shoulder imbalance into account, despite its importance as a clinical parameter and outcome measure.Purpose of the study
Introduction
The use of thoracic pedicle screws for the treatment of adolescent idiopathic scoliosis (AIS) has gained widespread popularity. Many techniques has been described to increase the accuracy of free hand placement; however the placement of pedicle screws in the deformed spine poses unique challenges because of possible neurologic and vascular complications. We are describing a universal way of insertion of pedicle thoracic screws which has been applied in many pathologies including the deformed spine. Our technique includes exposure of the superior facet of the corresponding body to identify its lateral border border which together with the superior border of the TP denotes our entry point which is just lateral to this crossing, we make a short entry with a straight Lenke probe then continue the track with a strong ball probe to go safely through the cancellous bone of the body. This is retrospective review of radiographs and clinical notes of all the patients who underwent posterior thoracic instrumentation by pedicle screws using the same single technique by one surgeon between June 2008 and December 2009; 1653 screws in 167 consecutive patients (119 females and 48 males). There were 139 deformities, 130 scoliosis (AIS 80, Congenital 31, Neuromuscular 10 and Degenerative 9), 19 kyphosis and 18 other diagnoses (fractures 14, revision 3 and tumour 1).Introduction
