Item Reverse total shoulder arthroplasty for failed treatment of proximal humerus fractures(TURKISH ASSOC ORTHOPAEDICS TRAUMATOLOGY, 2021-01-01) Karademir, Gokhan; Tunali, Onur; Ersen, Ali; Akpinar, Sercan; Atalar, Ata CanObjective: The aim of this study was to evaluate the functional and radiological outcomes and complications of reverse total shoulder arthroplasty (RTSA) for failed treatment of proximal humerus fractures (FTPHF). Methods: In this retrospective study, 20 patients (17 female, 3 maleItem 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, UnsalThe 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.
