    Does pedicle screw density matter in Lenke type 5 adolescent idiopathic scoliosis?
    (LIPPINCOTT WILLIAMS \& WILKINS, 2018-01-01) Sariyilmaz, Kerim; Ozkunt, Okan; Karademir, Gokhan; Gemalmaz, Halil Can; Dikici, Fatih; Domanic, Unsal
    The aim of this study is to compare the effects of high versus low implant density on correction in Lenke type 5 adolescent idiopathic scoliosis (AIS) patients. A retrospective study of 59 Lenke type 5 AIS patients treated at a single institution were divided into to 2 groups according to implant density. Implant density, preoperative, early postoperative, and last follow-up thoracolumbar/lumbar (TL/L) curves were measured. Thirty-one constructs were high and 28 constructs were low density. The groups were similar in terms of age, sex, Cobb angle, and follow-up time. Mean implant density in low density group and high density group was 75.4\% and 96.6\%, respectively. High versus low-density comparison showed that there is no significant difference with regard to curve correction in early postoperative and last follow-up periods. The results show that pedicle screw density being low or high, does not affect curve correction rates in the short and long term in our patients.

    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.
