    Study Design: trospective analysis of adolescent idiopathic scoliosis. Purposep: s study aimed to investigate the influence of distinct distal fusion levels on spinopelvic parameters in patients with adolescent idiopathic scoliosis (AIS) who underwent posterior instrumentation and fusion surgery. Overview of Literature: e distal fusion level selection in treatment of AIS is the one of milestone to effect on surgical outcome. Most of the paper focused on the coronal deformity correction and balance. The literature have lack of knowledge about spinopelvic changing after surgical treatment and the relation with distal fusion level. We evaluate the spinopelvic and pelvic parameter alteration after fusion surgery in treatment of AIS. Methods: total of 100 patients with AIS (88 females and 12 males) were retrospectively reviewed. Patients were assigned into the following three groups according to the distal fusion level: lumbar 2 (L2), lumbar 3 (L3), and lumbar 4 (L4). Using a lateral plane radiograph of the whole spine, spinopelvic angular parameters such as thoracic kyphosis (TK), lumbar lordosis (LL), pelvic incidence (PI), sacral slope (SS), and pelvic tilt (PT) were radiologically assessed. Results: e mean age was 15+/-2.4 years, and the mean follow-up period was 24.27+/-11.69 months. Regarding the lowest instrumented vertebra, patients were categorized as follows: 30 patients in L2 (group 1), 40 patients in L3 (group 2), and 30 patients in L4 (group 3). TK decreased from 36.60+/-13.30 degrees preoperatively to 26.00+/-7.3 degrees postoperatively in each group (p=0.001). LL decreased from 52.8+/-9.4 degrees preoperatively to 44.30+/-7.50 degrees postoperatively (p=0.001). Although PI showed no difference preoperatively among the groups, it was statistically higher postoperatively in group 3 than in the other groups (p<0.05). In addition, in group 2, PI decreased from 50.60+/-8.74 degrees preoperatively to 48.00+/-6.84 degrees postoperatively (p=0.027). SS decreased from 35.20+/-6.40 degrees preoperatively to 33.40+/-5.80 degrees postoperatively (p=0.08, p>0.05). However, mean SS was significantly higher in group 3 (p=0.042, p<0.05). PT decreased from 15.50+/-7.90 degrees preoperatively to 15.2+/-7.10 degrees postoperatively. The positive relationship (28.5\%) between LL and PI measurements was statistically significant (r=0.285

    Aarskog-Scott syndrome: An unusual cause of scoliosis
    (MEDKNOW PUBLICATIONS \& MEDIA PVT LTD, 2017-01-01) Sariyilmaz, Kerim; Ozkunt, Okan; Korkmaz, Murat; Dikici, Fatih; Domanic, Unsal
    A 16-year-old boy who had been diagnosed previously as Aarskog-Scott syndrome (AAS), referred to our clinic with shoulder asymmetry for 1 year. Results of spine examination showed a 52 degrees right thoracic curve at T3-T11. Surgery was planned, and T1-L1 posterior instrumentation and fusion were performed. After surgery, satisfactory correction was achieved, and during 10 years follow-up, the patient had no complaints. AAS is a X-linked genetic disorder with facial, genital, and skeletal manifestations. Scoliosis is not reported as a typical finding of AAS, and there is no reported case in the English literature. Due to mutation affecting the developing skeleton tissue, spinal deformities may develop. In our case, concave side fusion was seen at the deformity. Although we do not know any specific pattern of the scoliotic deformity of this syndrome, surgical correction of the deformity can be difficult because of the premature fusion at these levels.
