    Acute Measurement of Developmental Dysplasia of the Hip: Comparing Two Approaches for Measuring the Alpha Angle Using the Graf Technique
    (Sage Publications Inc, 2025) Dindar, Firat; Aylanc, Nilufer; Aylanc, Hakan; Ertem, Senay Bengin; Siddikoglu, Duygu; Resorlu, Mustafa
    Objective: The Graf method, in ultrasonography screening of developmental hip dysplasia, is based on angle measurements. Using different reference points may cause varied results. The aim of this study was to investigate to what extent the alpha angle obtained, varied at different reference points.Materials and Methods: There were 178 hips evaluated by two trained observers. Both measured the alpha angle with different reference points and these were labeled as methods A and B, for all the hips evaluated. The statistical analysis was performed with SPSS Version 21.Results: The average of observer 1, based on measurements with method A, were 65.63 (SD +/- 5.95) and based on method B were 73.39 (SD +/- 6.29). The average of the measurements of observer 2, utilizing method A were 64.39 (SD +/- 4.85) and based on method B were 69.92 (SD +/- 6.08). It was observed that method B showed higher mean and variability compared to method A. The agreement between observers was moderate in method A and poor in method B. The intraobserver correlation coefficient (ICC) was 0.69 for method A and 0.47 for method B. The ICC was considered good (e.g., 95%) for both observers in terms of using methods A and B.Conclusion: The use of ultrasonography still maintains its place in the diagnosis of developmental hip dysplasia. The Graf method is based on precise measurements, and the most decisive parameter is the alpha angle. Reference points in method A would be more useful in patient management and may increase the diagnostic accuracy.

    Isolated muscle involvement in hydatid cyst
    (Bmj Publishing Group, 2024) Ertem, Senay Bengin; Resorlu, Mustafa; Aylanc, Nilufer; Kamis, Fatih
    Although hydatid cyst, caused by Echinococcus granulosus, can develop in any part of the body, involvement of the liver and lung represents approximately 90% of all cases. Involvement of the musculoskeletal system is comparatively rare. Diagnosis is difficult because symptoms are non-specific. We present a case, together with the imaging findings, in order to draw attention to the exclusion of hydatid cyst before surgery or biopsy in patients with muscular pain and a palpable mass.

    The Relationship Between Breast Volume and Thoracic Kyphosis Angle
    (Pera Yayincilik Hizmetleri, 2024) Ertem, Senay Bengin; Malcok, Umit Ali
    Objective: It has been hypothesized that a disproportionate upper body weight caused by macromastia places abnormal stress on the spine, which may lead to skeletal abnormalities. To evaluate whether there is a relationship between breast volume and the thoracic kyphosis angle measured on thorax CT images. Methods: A total of 448 female patients who underwent thoracic CT examinations were included in this study. Breast volume (ml), by using the organ segmentation method; thoracic kyphosis angles by using Cobb's method were made manually on the workstation. Results: Mean right breast volume was 902.03 +/- 376.47 (154.21 - 2366.20 ml), left breast volume was 911.01 +/- 383.34 (167.93 - 2894.07 ml), total breast volume was 1810.09 +/- 750.82 (354.39 5100.68 ml). The total breast volume (p<0.001) and thoracic kyphosis angle (p=0.012) in patients aged 50-69 years were significantly higher than those aged 17-29 years. Larger total breast volume [p<0.001] and thoracic kyphosis angle (p<0.001) values were associated with larger BMI intervals. A significant positive correlation was observed between the total breast volume and thoracic kyphosis angle (r=0.771, p<0.001). Conclusion: Our results showed that the thoracic kyphosis angle significantly increased in parallel with a larger total breast volume, and that total breast volume was an independent risk factor for thoracic kyphosis angle. The manual organ segmentation method we used was found to be reliable and easy to apply, but time-consuming technique for calculating BV.
