    (Maltepe Üniversitesi, 2013) Şanel, Selim; Ünsal, Faik Murat; Ermiş, Nurullah; Ugutmen, Ender; Solakoğlu, Can
    Amaç: Ayak bileği lateral bağlarının kronik lezyonlarında, Colville tekniğinin uygulandığı genç hastalardaki sonuçların değerlendirilmesi. Metod: 2008-2010 yılları arasında kronik ayak bileği lateral instabilitesi olan yedi erkek bir bayan hastaya (ort. yaş 22; yaş dağılımı 20-35) güçlendirilmiş Colville tekniğiyle rekonstrüksiyon uygulandı. Yaralanmadan ameliyata kadar geçen süre ortalama 29 ay idi (dağılımı 21-33 ay). Sekiz hastada da Trevino'nun değerlendirme kriterlerine göre tip IIIc ayak bileği lateral bağ lezyonu vardı. Olgular ortalama 42 ay süreyle (dağılım 24-60 ay) takip edildi. Bulgular: Tüm olgularda mükemmel sonuç elde edildi. Hiçbir hastada reküren instabilite gözlenmedi. Enfeksiyon, sural sinir lezyonu gibi komplikasyonlara rastlanmazken 1 hastada sınırlı yüzeyel cilt nekrozu saptandı. Sonuç: Colville tekniğiyle, stabilite %100'e yakın oranlarda sağlanırken, subtalar eklem hareketleri de korunmaktadır.

    Comparison of intra-articular bupivacaine-morphine with bupivacaine-tenoxicam combinations on post-operative analgesia in patients with arthroscopic meniscectomy: a prospective, randomised study
    (SPRINGER, 2016) Sanel, Selim; Arpaz, Osman; Unay, Koray; Turkmen, Ismail; Simsek, Selcuk; Ugutmen, Ender
    Aim There are many alternatives for post-operative pain relief in patients who have had general anaesthesia. The aim of this study was to evaluate the efficacy of intra-articular bupivacaine + morphine and bupivacaine + tenoxicam applications in post-operative pain control in patients undergoing knee arthroscopy with general anaesthesia. Method This was a prospective study. Standard anaesthesia procedures were applied to each patient, and the 240 patients chosen at random were then divided into two groups. Each group received a different combination of drugs for this double-blind study. The first group (group A: 120 patients) received 0.5 % bupivacaine 100 mg + tenoxicam 20 mg (22 ml); the second group (group B) received 0.5 % bupivacaine 100 mg + morphine 2 mg (22 ml); both groups received their drugs at the end of the intra-articular operation before tourniquet deflation. Before the operation, patients were asked about their post-operative pain at particular periods over the following 24 hours using the visual analogue scale (VAS) and the numeric rating scale (NRS). An additional analgaesic requirement and possible side effects were also recorded. Results Group A patients needed analgaesics sooner after operation than patients in group B. In Group B, VAS and NRS values were statistically higher compared with group A at the 12th hour. There were also fewer side effects seen in group A versus group B. Conclusion Effective and reliable results were obtained in post-operative pain control in bupivacaine added to the morphine or tenoxicam groups following arthroscopic meniscectomy. In the tenoxicam group, patients reported less pain, fewer side effects and less need for analgesics at 12 hours after the operation.

    Morphological and biomechanical effects of vitamin K2 on fracture healing: An animal study on the rat tibia fracture model
    (Turkish Assoc Orthopaedics Traumatology, 2023) Ünal, Ömer Kays; Dağtaş, Mirza Zafer; Ipek, Belkiz Ongen; Sitar, Mustafa Erinc; Ugutmen, Ender
    Objective: The aim of this study was to evaluate the effects of vitamin K2 on fracture healing.Methods: Twenty-four 6-week-old male Wistar albino rats that had open tibia fractures induced were included in this study. They were divided into 2 groups of 12, a group that had vitamin K2 administered over 30 consecutive days and a control group. After 30 days, the rats were sacrificed, and from each group, 6 tibiae were selected for biomechanical testing to examine the mechanical strength of the callus tissue using the Instron 3-point bending test and 6 tibiae were selected for histological analysis to examine the density and organization of callus tissue using Allen's grading system and Huo et al's grading system. Furthermore, weekly x-rays were taken to evaluate bone union described by Lane and Sandhu, and osteocalcin, procollagen I N-terminal propeptide, and procollagen I C-terminal propeptide were examined in blood samples taken by intracardiac puncture during sacrification.Results: Breaking force (P = .047), breaking time (P = .019), stiffness (P = .039), fracture strength (P = .041), and Young's modulus (P = .032) showed a statistically significant increase in the K2 group. Procollagen I C-terminal propeptide (P = .024), procollagen I N-terminal propep -tide (.047), and osteocalcin (.048) levels were significantly higher in the K2 group compared to the control group. Furthermore, 3rd-week x-rays showed higher bone union scores according to the Lane and Sandhu method in the K2 group (P = .014). However, the histological grading systems of Allen and Huo et al did not show statistically significant differences between groups (P = .086, P = .07, respectively).Conclusion: In light of these findings, it could be concluded that vitamin K2 has a significant positive effect on fracture healing.

    Novel lateral support system increases stability and reduces angular error in total hip arthroplasty: a case control study
    (JOSAM, 2022) Dağtaş, Mirza Zafer; Ünal, Ömer Kays; Najafov, Turan; Ugutmen, Ender
    Background/Aim: Intraoperative changes in patient position or other changes that would disrupt the decisive position during preoperative preparation would directly have a negative impact on acetabular cup orientation in patients undergoing total hip arthroplasty. This study aimed to compare the standard support system and a novel lateral support system (Maltepe), which ensures stable lateral decubitus positioning during the perioperative period, in patients undergoing total hip arthroplasty with the posterolateral approach. Methods: Patients operated in our department for osteoarthritis of the hip between 2012 - 2019 were included in this case-control study retrospectively. 46 and 41 patients were prepared for surgery in lateral decubitus position using the classical (Group 1) and novel (Group 2) lateral support systems, respectively. The groups were compared in terms of demographic characteristics, duration of preparation, anteversion and inclination, and Harris Hip scores. Results: Mean patient age was 66.89 (7.53). There was no significant difference between the two groups in terms of age (P=0.546), gender (P=1.00), body mass index (P=0.302) and the operative side (P=0.724). Duration of preparation and absolute deviation values from 15 degrees and 45 degrees were significantly better in group 2 compared to group 1 (P<0.01). There was no significant difference between the Harris Hip Scores of two groups. Conclusion: We demonstrated that the novel support system we developed provided more successful outcomes than the classical system in terms of acetabular cup orientation.
