    (Turkish Assoc Orthopaedics Traumatology, 2010) Atay, Evren Fehmi; Güven, Melih; Altıntaş, Faik; Kadıoğlu, Barış; Ceviz, Emrah; İpek, Serdar
    Objectives: We aimed to evaluate the effectiveness of postoperative autotransfusion method on prevention of the need of allogeneic blood transfusion in hip and knee arthroplasty. Methods: Seventy-four patients who underwent 77 hip and knee arthroplasty operations were randomized into control and study groups, and evaluated prospectively. In the knee group (39 patients; 30 females, 9 males; mean age 66.6 years), cemented, cruciate retaining, and bicompartmental arthroplasty was performed under tourniquet control; whereas in the hip group (35 patients; 24 females, 11 males; mean age 59.3 years) cementless arthroplasty with posterolateral approach was performed. None of the patients received preoperative and intraoperative allogeneic blood transfusion. The collected blood in the surgical area was transfused with autotransfusion system to the patients in the study groups at the end of the fourth hour postoperatively. The mean amounts of autotransfused blood in hip and knee groups were 413 mL and 480 mL, respectively. Allogeneic blood transfusion was applied to the patients with hemoglobin level below 8 g/dL, hematocrit level below 25%, and clinical symptoms of anemia. Results: Preoperative and postoperative hemoglobin-hematocrit levels did not differ significantly between study and control groups. Allogeneic blood transfusion was applied to one patient (5%) in study and 8 patients (38%) in control groups during knee arthroplasty (p=0.01); whereas 9 patients (53%) in study and 15 patients (79%) in control groups received allogeneic blood transfusion during hip arthroplasty (p=0.044). The amount of allogeneic blood transfusion in study groups was significantly lower than that in control groups (p=0.008 for knee arthroplasty, p=0.048 for hip arthroplasty). Conclusion: The need and amount of allogeneic transfusion were reduced with postoperative autotransfusion in both knee and hip arthroplasty groups with greater extent in knee arthroplasty.

    Can bone quality be predicted accurately by Singh Index in patients with rheumatoid arthritis?
    (Springer London Ltd, 2012) Bes, Cemal; Güven, Melih; Akman, Budak; Atay, Evren Fehmi; Ceviz, Emrah; Soy, Mehmet
    The aim of this study was to evaluate Singh index as a simple and inexpensive means of estimation of bone quality in patients with rheumatoid arthritis. Singh index evaluation was made on digital pelvis radiographs in 50 consecutive patients by three observers. Bone mineral density T scores of the spine and left proximal femur were assessed using dual energy X-ray absorptiometry. Singh index was correlated with densitometry measurements after grouping the patients as normal, osteopenia and osteoporosis. Intra-and interobserver agreements were evaluated by kappa correlations. Sensitivity, specificity, positive and negative predictive values and likelihood ratio's of Singh index were calculated. Both intra-and interobserver agreements were 0.71 (range, 0.69 to 0.72) on average. Singh index proved highly sensitive for the diagnosis of osteopenia at the proximal femur (91%) and spine (90%), whereas the specificity of Singh index for identifying of osteoporosis at the femoral neck (93%) and spine (91%) was higher than sensitivity. Predictive values for osteoporosis at the proximal femur and spine were acceptable and positive likelihood ratios of Singh index for osteopenia and osteoporosis at the proximal femur were 2.4 and 10.1, respectively. Singh index can identify osteoporosis with a high specificity in patients with rheumatoid arthritis. However, the patients who are graded as osteopenia by the Singh index should undergo further evaluation with dual energy X-ray absorptiometry.

    Kalça ve diz artroplastisinde ameliyat sonrası ototransfüzyon allojenik kan transfüzyonunu azaltır
    (2010) Atay, Evren Fehmi; Güven, Melih; Altıntaş, Faik; Kadıoğlu, Barış; Ceviz, Emrah; İpek, Serdar
    Amaç: Bu çal›flmada kalça ve diz artroplastisinde ameliyat sonras› uygulanan ototransfüzyon yönteminin allojenik kan transfüzyonu ihtiyac›n› önlemedeki etkinli¤inin de¤erlendirilmesi amaçlanm›flt›r. Çal›flma plan›: Total kalça ve diz artroplastisi uygulanm›fl 74 hasta (77 artroplasti giriflimi) ça- l›flma ve kontrol gruplar›na randomize edilerek prospektif olarak de¤erlendirildi. Diz grubunda (39 hasta; 30 kad›n, 9 erkek; ortalama yafl 66.6) standart yaklafl›mla turnike kontrolünde çimen- tolu, kalça grubundaysa (35 hasta; 24 kad›n, 11 erkek; ortalama yafl 59.3) posterolateral yakla- fl›mla çimentosuz artroplasti uyguland›. Hiçbir hastaya ameliyat öncesinde ve s›ras›nda allojenik kan transfüzyonu yap›lmad›. Çal›flma gruplar›ndaki hastalarda ameliyat sonras› 4. saatte cerrahi sahada biriken kan ototransfüzyon seti ile transfüze edildi. Kalça ve diz çal›flma gruplar›nda or- talama ototransfüzyon miktarlar› s›ras›yla 413 mL ve 480 mL idi. Banka kan› transfüzyonu; he- moglobin 8 gr/dL’nin, hematokrit ise %25’in alt›nda oldu¤u ve klinik olarak anemi bulgular›n›n efllik etti¤i hastalarda uyguland›. Sonuçlar: Çal›flma ve kontrol gruplar› aras›nda ameliyat öncesi ve sonras› hemoglobin-hematok- rit de¤erlerinde istatistiksel anlaml› fark yoktu. Diz hastalar›nda çal›flma grubunda 1 (%5), kon- trol grubunda 8 (%38) (p=0.01); kalça hastalar›nda ise çal›flma grubunda 9 (%53), kontrol gru- bunda 15 (%79) hastada (p=0.044) banka kan› transfüzyonu yap›ld›. Çal›flma gruplar›nda alloje- nik transfüzyon miktar› kontrol gruplar›na göre anlaml› olarak düflüktü (diz grubu p=0.008, kal- ça grubu p=0.048). Ç›kar›mlar: Diz ve kalça artroplastisinde ototransfüzyon yöntemiyle diz artroplastisinde daha belirgin olmak üzere allojenik kan transfüzyonu ihtiyac› ve transfüzyon miktar› azalmaktad›r.

    An unusual cause of a cystic lesion with an osteochondral defect in the talus intraosseous lipoma
    (Amer Podiatric Med Assoc, 2011) Atay, Evren Fehmi; Güven, Melih; Çakar, Murat; Başsorgun, Cumhur İbrahim; Akman, Budak; Beş, Cemal
    An intraosseous lipoma is a rare benign bone lesion that proliferates from mature lipocytes. It occurs most frequently in the lower limb, particularly in the calcaneus. The talus is an unusual location for this rare lesion. A review of the literature produced only two reports with talar intraosseous lipomas under the name of intraosseous lipomatosis, which described multiple lipomas in different areas. We describe a 38-year-old male patient who had an isolated intraosseous lipoma with an osteochondral defect in the talus and was treated with autologous osteochondral graft transplantation by medial malleolar osteotomy. He could walk with full weightbearing without any assistance at the end of 12 months. Intraosseous lipoma localized in the talus may be confused radiologically with other bone lesions, especially with unicameral bone cyst, if it is associated with an osteochondral defect. Autologous osteochondral graft transplantation is a successful treatment method for talar intraosseous lipoma. (J Am Podiatr Med Assoc 101(3): 269-274, 2011)
