    Acetabular Development Following Salter’s Innominate Osteotomy for the Treatment of Developmental Dysplasia of the Hip: Long Term Follow-Up
    (Scientific Research Publishing, 2016-04) Turhan, Yalçın; Kılıç, Bülent; Demiroğlu, Murat; Uygur, Esat; Özkan, Korhan; Eren, Abdullah
    Aim: To investigate the long term results of the patients followed till the skeletal maturity and treated with Salter innominate osteotomy. Patients and Methods: 85 hips of 63 patients whom were operated by the same surgeon between the years 1985 and 1991 were evaluated retrospectively. 34 hips of 25 patients who did not have enough follow-up or did not reach skeletal maturity at their last radiographic control were excluded from the study. So, 51 hips of 38 patients were included into our study. Mean age of the patients at the time of operation was 3 years 2 months (1.5 - 11 years), mean follow-up time was 16 years 6 months (10 - 23 years) and mean age at the last control was 19 years 7 months (15 - 27 years). Results: The overall clinical results were favorable (excellent or good) in 48 hips (94.1%) according to the modified McKay clinical evaluation scale. Avascular necrosis was evaluated with the Kalamchi-McEven classification at the last follow up and 45 hips (88.2%) had no avascular necrosis. The radiographic results were assessed by the Severin classification system and 10 hips (19.6%) were stage 1a; 10 hips (19.6%) were stage 1b; and 30 hips (58.8%) were stage 2. Upon the analysis of our radiographic results according to Stulberg classification system, we found out that only 2 (3.9%) of our patients were Stulberg stage 5, whereas 36 cases (70.6%) were Stulberg stage 1 and 2 (spherical congruency). According to Croft’s classification of hips for degenerative changes, 36 (70.6%) patients were stage 0; 6 (11.8%) patients were stage 1; 5 (9.8%) patients were stage 2 and 4 patients (8.7%) were stage 3. Conclusion: When appropriate soft tissue balance is provided, the complications of Salter Innominate Osteotomy are decreased and thus, it provides an excellent functional and radiological result.

    Subchondral Bone and Its Role in Osteoarthritis
    (Scientific Research Publishing, 2015-11) Uygur, Esat; Kılıç, Bülent; Demiroğlu, Murat; Özkan, Korhan; Çift, Hakan Turan
    Osteoarthritis (OA) is the most prevalent form of arthritis and one of the leading causes of chronic disability which is becoming more pronounced as the population ages. Various genetic, biologic and mechanical factors contribute to disease process in OA. A large cascade of events leads to breakdown and degeneration of cartilage in a progressive manner ultimately resulting in the damage of the joint including the subchondral bone. Although majority of attention was given to chondral surface of the joint in the past, recently subchondral bone has been taken more and more attention during the investigation of degenerative phase in osteoarthritis. In our review we aimed to review the processes that were taken place during the osteoarthrosis especially in the sub-chondral bone and to give a new point of view for the further investigations.

    An unusual presentation of Trevor's disease at the ankle joint: Involvement of both medial and lateral epiphyses
    (Churchill Livingstone, 2018) Uygur, Esat; Demiroğlu, Murat; Aydin, Davut; Kiliç, Bülent; Özkan, Korhan
    Introduction: Trevor's disease, also known as dyplasia epiphysealis hemimelica, is characterised by osteochondromas arising from epiphyses. The disease typically affects one side of an epiphysis (usually the medial side). Case presentation: A case in whom both the medial and lateral sides of the epiphysis were involved is described. Thus, the use of the descriptor “hemimelica” is not always appropriate. Conclusion: Although rare, Trevor's disease should be kept in mind during the differential diagnosis of patients with ankle pain and a mass. Other possible joints should be examined to explore multiple involvement. Surgical treatment, only on lesions causing impingements, may improve functional status and reduce pain. © 2018 Elsevier Ltd
