    Objectives: The aim of the study was to investigate whether clavicular symmetry was a valid assumption and to assess the factors that could predict clavicular asymmetry. Patients and methods: Between January 2021 and April 2021, a total of 100 consecutive patients (61 males, 39 females; mean age: 63.6 +/- 15.5 years; range, 27 to 94 years) whose both clavicles were adequately seen on chest computed tomography (CT) were retrospectively analyzed. Clavicular lengths were measured on three-dimensional (3D) reconstruction of chest CTs by two independent orthopedic surgeons on two separate occasions. The longest distance passing the straight line between the most lateral part of the clavicle at the acromioclavicular joint and the most medial point of the clavicle on the sternoclavicular joint was given as the clavicle length after adjusting tilt of convertible 3D CTs. Clavicular length difference was calculated by subtracting the short clavicle's length from the long clavicle's length. Patients' age and sex were noted. The calculated clavicular length differences were assigned into three groups: =5 mm, > 5 mm and =10 mm, and > 10 mm. Results: The mean right and left clavicle lengths were 13.9 +/- 1.3 cm and 14.1 +/- 1.2 cm, respectively (p < 0.001). A total of 29 patients (29%) had > 5 mm clavicle asymmetry and six patients (6%) had more than 10 mm clavicular length difference. Age, sex, and clavicular length were not associated with the clavicular length difference. Conclusion: Our study results showed that 29% of the patients had > 5 mm clavicular length asymmetry. The clavicular symmetry may not be a valid assumption in the decision making for the surgical treatment of mid-shaft clavicle fractures; thus, this assumption may lead to maltreatment.

    What is the importance of distal nail diameter in the treatment of intertrochanteric femur fractures?
    (Turkish Joint Diseases Foundation, 2022) Ergisi, Yilmaz; oezdemir, Erdi; Korkmazer, Selcuk; Kekec, Halil; Altun, Ozan; Yalcin, Nadir
    Objectives: The aim of this study was to investigate the effect of distal nail diameter in the treatment of geriatric intertrochanteric femur fractures (ITFFs).Patients and methods: Between January 2017 and January 2021, a total of 91 patients (34 males, 57 females; mean age: 80.6 +/- 7.8 years; range, 65 to 96 years) who had osteosynthesis due to an ITFF with a short cephalomedullary nail (CMN) were retrospectively analyzed. The patients were divided into two groups: Group 1 (n=18) included patients with a distal nail diameter of <= 10 mm and Group 2 (n=73) included patients with a distal nail diameter of >10 mm. Patients' age, sex, fracture type according to AO classification, intramedullary femoral canal diameter, canal fit ratio, operation duration, reduction quality, the distal diameter of the CMN, and complications were evaluated.Results: There was no statistically significant difference between Group 1 and Group 2 in terms of the mean age, sex, fracture type, mean intramedullary canal diameter, reduction quality, and implant failure (p>0.05). The mean operation duration was significantly shorter in Group 2 (112.9 +/- 39.9 min) compared to Group 1 (128.8 +/- 36.4 min) (p=0.048). A total of three intraoperative peri-implant fractures occurred which included one 9 mm nail, one 12 mm nail, and one 14 mm nail.Conclusion: Our study results suggest that there is no advantage of using a >10-mm CMN in the treatment of geriatric ITFFs in terms of reducing the implant failure rate. However, the utility of a >10-mm CMN can reduce the operation duration.
