Öğe The epidemiology of adult fractures according to the AO/OTA fracture classification(Turkish Assoc Trauma Emergency Surgery, 2022) Bilge, Onur; Dundar, Zerrin Defne; Atilgan, Numan; Yaka, Haluk; Kekec, Ahmet Fevzi; Karaguven, Dogac; Doral, Mahmut NedimBACKGROUND: The epidemiology of adult fractures has been changing timely, in a multifactorial fashion. The aim of this study was to put forward a recent 5-year epidemiological analysis of adult fractures, according to the current AO/OTA fracture classification, in the current decade of action for road safety. METHODS: 5324 adult patients who were diagnosed with at least one fracture related with orthopedics and traumatology in a level-one trauma center were included in this retrospective, epidemiological descriptive study. The patients were grouped according to their ages as; 18-35, 36-55, 56-69, and >= 70. The fractures were examined according to the AO/OTA classification. RESULTS: 5865 fractures were present in 5324 patients. The mean age of the patients was 48.6 +/- 21.5. The number of patients according to the age groups was as follows; 1947 (36.6%), 1636 (30.7%), 881 (16.5%), and 860 (16.2%), respectively. The most frequent three fractures according to the AO/OTA fracture classification were; 7 (hand 19.6%), 23 (distal forearm, 12.1%), and 8 (foot, 11.8%). About 54.4% and 45.4% of the patients were treated non-surgically and surgically, respectively. About 0.2% of the patients preferred an alternative treatment. Overall mortality rate was 0.4%. CONCLUSION: To the best of our knowledge, this study represents the first analysis of adult fractures according to the AO/OTA classification, over a 5-year period. As a future prospect, further multi-centric epidemiological studies are warranted to constitute a sustainable action plan for the prevention of major traumas.Öğe The epidemiology of adult fractures according to the AO/OTA fracture classification(Turkish Assoc Trauma Emergency Surgery, 2022) Bilge, Onur; Dundar, Zerrin Defne; Atilgan, Numan; Yaka, Haluk; Kekec, Ahmet Fevzi; Karaguven, Dogac; Doral, Mahmut NedimBACKGROUND: The epidemiology of adult fractures has been changing timely, in a multifactorial fashion.

The aim of this study was to evaluate the relationship between greater tuberosity primary bone marrow edema (GTPBMO) and vitamin D levels. Materials and MethodsThirty-nine patients (22 females and 17 males; mean age 49.02 +/- 13.08 years) with isolated GTPBMO between March 2016 and March 2018 were included in the study. Sixty patients (34 females and 26 males; mean age 43.45 +/- 12.61 years) who did not have any shoulder complaints and fulfilled the study criteria were selected as the control group. Both groups were compared in terms of vitamin D levels. ResultsThe mean vitamin D level was 13.43 +/- 9.02 ng/mL in the GTPBMO group. In contrast, mean vitamin D level was 21.54 +/- 8.03 ng/mL in the control group (p < 0.001). In the GTPBMO group, vitamin D deficiency was detected in 31 (79.5%) patients, vitamin D insufficiency was detected in 5 (12.8%) patients, and vitamin D levels were normal in 3 (7.7%) patients. In the control group, vitamin D deficiency was detected in 29 (48.3%) patients, vitamin D insufficiency was detected in 16 (26.7%) patients, and vitamin D levels were normal in 15 (25%) patients. ConclusionThe etiology of GTPBMO has not yet been fully understood, but the results obtained in this study show that vitamin D levels were significantly lower in patients with GTPBMO. The findings suggest that low vitamin D levels may be one of the contributing factors in the etiology of GTPBMO.Öğe Evaluation of the relationship between lateral epicondylitis and vitamin D(Turkish Joint Diseases Foundation, 2022) Yaka, Haluk; Basbug, Veysel; Tekin, Alper Aziz; Ozer, MustafaObjectives: This study aims to examine the relationship between low vitamin D levels and lateral epicondylitis (LE). Patients and methods: Between January 2016 and January 2018, a total of 40 patients (17 males, 23 females; mean age: 38.6 +/- 10.7 years; range, 18 to 59 years) diagnosed with LE were included as the study group, while 66 patients (33 males, 33 females; mean age: 33.6 +/- 12.5 years; range, 18 to 58 years) who did not have any elbow complaints and met the study criteria were included as the control group. Both groups were compared in terms of vitamin D levels, of which levels of >30 ng/mL were considered normal, levels between 20-30 ng/mL were accepted as vitamin D insufficiency, and levels <20 ng/mL were categorized as vitamin D deficiency. Results: Vitamin D levels of the LE group were significantly lower than the control group (p<0.001). The mean vitamin D level was 16.47 +/- 8.22 (range, 8.32 to 39.55) ng/mL in the LE group, and 23.64 +/- 8.4 (range, 11.6 to 49) ng/mL in the control group. While 31 of the patients (77.5%) diagnosed with LE had vitamin D deficiency, four (10%) had vitamin D insufficiency, and five (12.5%) had normal vitamin D levels. In the control group, 29 (43.9%) patients had vitamin D deficiency, 20 (30.3%) had vitamin D insufficiency, and 17 (25.8%) had normal vitamin D levels. Conclusion: Although the etiology of LE has not been fully understood yet, vitamin D levels were significantly lower in LE patients in our study. This finding supports that low vitamin D may be one of the factors in the etiology of LE.Öğe Evaluation of the relationship between scapula morphology and anterior shoulder dislocation accompanying greater tuberosity fracture(Elsevier Sci Ltd, 2023) Ozer, Mustafa; Yaka, Haluk; Turkmen, Faik; Kacira, Burkay Kutluhan; Kaptan, Ahmet Yigit; Kanatli, UlunayIntroduction: It is estimated that 5-30% of traumatic anterior shoulder dislocations are accompanied by greater tuberosity fracture (GTF), and the pathomechanism of these fractures is not yet clear. Our hypothesis is to examine the relationship between the scapula morphology and anterior shoulder dislocation (ASD) accompanying GTF. Materials and methods: The patients were divided into two groups according to the accompanying GTF. 40 patients with isolated traumatic ASD and 31 patients with accompanying GTF were included in the study. Critical shoulder angle (CSA), glenoid inclination (GI), acromial index (AI) and greater tuberosity angle (GTA) values were measured in two sessions by two independent observers in the standard antero-posterior radiographs of the patients in both groups. Results: The mean CSA was 40.82 degrees +/- 3.19 degrees and 35.49 degrees +/- 2.19 degrees in accompanying GTF group and the isolated ASD group, respectively. The mean CSA was significantly higher in accompanying GTF group than isolated ASD group (P<0.001). The GI was significantly higher in the isolated ASD than in accompanying GTF group (P = 0.001). The mean GI was 18.7 degrees +/- 6.85 degrees and 10.45 degrees +/- 4.87 degrees in accompanying GTF group and the isolated ASD, respectively. Cut-off value of CSA and GI was 38 degrees (88.2% sensitivity,88.9% specificity) and 14.5 degrees (70.6% sensitivity and 72.2% specificity), respectively. There was no significant difference regarding the mean GTA and AI values between GTF group and the isolated ASD group (P = 0.98, P = 0.63). Conclusions: Increased CSA and GI values are associated with traumatic anterior shoulder dislocation accom-panied by greater tuberosity fracture.Öğe The initial analysis of pediatric fractures according to the AO/OTA fracture classification and mechanisms of injuries(Turkish Assoc Trauma Emergency Surgery, 2022) Bilge, Onur; Kekec, Ahmet Fevzi; Atilgan, Numan; Yaka, Haluk; Dundar, Zerrin Defne; Karaguven, Dogac; Doral, Mahmut NedimBACKGROUND: The epidemiology of pediatric fractures has been changing timely, in a multifactorial fashion.

This study aims to evaluate the relationship of LT with HH and glenoid in patients with Ssc tears and anterior shoulder instability (ASI). We hypothesized that the glenoid, HH, and their combined relationship with LT may impact Ssc tears and ASI. Material and methods: The study included 34 patients with ASI, 28 patients with isolated Ssc tears, and 40 patients as the control group. The radius of HH (Hr), the distance between the center of HH and LT (LTr), and the glenoid radius (Gr) were measured in shoulder magnetic resonance (MR) images. The LTr to Hr (LTr/Hr) ratio was defned as the lesser tuberosity humeral head index (LTHHI), whereas the LTr to Gr (LTr/Gr) ratio was defned as the lesser tuberosity-glenoid index (LTGI). The three groups were compared regarding LTHHI, LTGI, LTr, Hr, and Gr. Results: There was a signifcant diference between each group concerning LTGI (p<0.001). LTGI values below 1.99 showed 93.1% sensitivity and 93.3% specifcity for Ssc tears, while values above 2.24 showed 86.7% sensitivity and 86.2% specifc ity for ASI. Also, there was a signifcant diference when the groups were compared for LTHHI (p<0.001). This rate was lowest for Ssc tears, and LTHHI values below 1.17 showed 82.8% sensitivity and 80.1% specifcity. Conclusion: LTGI may be a new predictive factor showing 93.1% sensitivity and 93.3% specifcity for Ssc tears and 86.7% sensitivity and 86.2% specifcity for ASI. In addition, LTHHI may be a new predictive factor showing 82.8% sensitivity and 80.1% specifcity for Ssc tears. Level of evidence: III retrospective comparative study.Öğe Is medial or lateral localization of osteochondral lesions of talus related to foot angles?(Turkish Joint Diseases Foundation, 2024) Yaka, Haluk; Kesik, Kayhan; Basbug, Veysel; Kucuksen, Muhammed Furkan; Ozer, MustafaObjectives: This study aims to examine the relationship between foot angles and the presence and localization of osteochondral lesions of the talus (OLTs). Patients and methods: Between January 2014 and January 2019, a total of 152 patients with a diagnosis of medial OTLs (95 males, 57 females; mean age: 28.8 +/- 6.4 years; range, 18 to 40 years), 51 patients with a diagnosis of lateral OTLs (36 males, 15 females; mean age: 27.1 +/- 6.2 years; range, 18 to 39 years), and 114 patients without known foot-ankle trauma as the control group (56 males, 58 females; mean age: 29.0 +/- 6.1 years; range, 18 to 40 years) were included. Magnetic resonance imaging and radiographs of each group were analyzed retrospectively. Lateral talocalcaneal angle (LTCA), calcaneal inclination angle (CIA), Bohler angle (BA), and Gissane angle (GA) were measured on the images and the values were compared among the groups. Results: The CIA had a significant relationship with the localization (p < 0.001). It was higher in patients with OLTs and had an effect on localization. The mean CIA was 26.6 degrees +/- 3.9 degrees in the medial OLTs group, 23.0 degrees +/- 3.5 degrees in the lateral OLTs group, and 18.5 degrees +/- 3.6 degrees in the control group. There was a significant difference in the LTCA between the control and OLTs groups (p < 0.001). The LTCA was higher in patients with OLTs, but had no effect on localization. The mean LTCA was 41.1 degrees +/- 4.2 degrees for medial OLTs, 41.3 degrees +/- 4.2 degrees for lateral OLTs, and 35.7 degrees +/- 6.8 degrees for the controls. No significant relationship was found for BA and GA among the three groups. Conclusion: Factors affecting the localization of OLTs are still not fully understood. However, foot morphology seems to play a role in determining medial or lateral localization. The LTCA is not related to the localization of OLTs; however, an increased LTCA may be related to the occurrence of OLTS. Increased CIA may be related to both OLTS localization and OLTs occurrence.Öğe Is prenatal testosterone-estrogen balance related to critical shoulder angle?(Elsevier Ireland Ltd, 2023) Yaka, Haluk; Baako, Yahaya; Ozer, Mustafa; Kanatli, UlunayBackground: The 2D:4D ratio (an indicator of prenatal testosterone-estrogen balance) is the ratio of the second finger length to the fourth finger length. We hypothesized that low 2D:4D values indicating high prenatal testosterone exposure may be associated with increased critical shoulder angle (CSA).Aims: The aim of this study was to evaluate the relationship between CSA and 2D:4D ratio.Methods: Meeting the study criteria, 252 patients were included in the study. We measured CSA on true anterior-posterior radiographs, glenoid version(GV) and glenoid inclination(GI) on MRI images and the lengths of the second and fourth fingers on both hands of the patients. Additionally, we compared 2D:4D ratios and CSA, GV, GI measurements.Results: We found a significant negative correlation between CSA and the 2D:4D ratio in both hands (p < 0.001). Patients with CSA > 35 degrees had a significantly lower 2D:4D ratio than patients with CSA < 35 degrees (p < 0.001). When the patients were grouped according to CSA35 degrees, the cut-off value for the left-hand 2D:4D ratio was 0.96, which showed 84.8 % sensitivity and 83.3 % specificity(AUC:0.911). Patients were compared in terms of CSA by categorizing as 2D:4D > 1 and 2D:4D < 1. Accordingly, the CSA value was significantly lower in patients with 2D:4D > 1. In the classification made according to this length classification of the left hand, the cut-off value was 30.25 degrees. This value showed 92.2 % sensitivity and 85 % specificity(AUC:0.956).Conclusion: The 2D:4D ratio is related to CSA. A low 2D:4D ratio(<0.96), indicating high intrauterine testosterone exposure, is associated with CSA > 35 degrees, while a high 2D:4D ratio (>1), indicating low intrauterine testosterone exposure, is associated with a low CSA(<30.25 degrees).Öğe Is the ratio of the index to ring finger length, a potential marker for prenatal testosterone-estrogen balance, related to posterior tibial slope?(Elsevier, 2023) Yaka, Haluk; Ozer, MustafaBackground: The 2D:4D ratio, an indicator of prenatal testosterone-estrogen balance, is the index finger (second finger) size's ratio to the ring finger (fourth finger) size. Asymmetric growth in the proximal tibial growth plate is considered to cause the increased posterior tibial slope (PTS) formation. Factors determining the amount of this asymmetry still need clarification. This study aims to evaluate the relationship between the 2D:4D ratio, which indicates the prenatal testosterone-estrogen balance, and the PTS. Method: Meeting the study criteria, 267 patients were included in the study. We measured the medial PTS (MPTS) and lateral PTS (LPTS) on MRI images and the lengths of the second and fourth fingers on both hands of the patients. Additionally, we compared 2D:4D ratios and MPTS and LPTS measurements. Results: We found a significant negative correlation between MPTS and the 2D:4D ratio, as well as between LPTS and the 2D:4D ratio in both hands (MPTS left vs. right hand: P < 0.001, r = -0.627 vs. P < 0.001, r = -0.498) (LPTS left vs. right hand: P < 0.001, r = 0.589 vs. P < 0.001, r = 0.404). Separately among males and females, there was a significant negative correlation between MPTS and the 2D:4D ratio, as well as between LPTS and the 2D:4D ratio in both hands (for males: MPTS left vs. right hand: P < 0.001, r = -0.607 vs. P < 0.001, r = -0.540)(for males: LPTS left vs.right hand: P < 0.001, r = 0.451 vs. P < 0.001, r = 0.406) (for females:MPTS left vs. right hand: P < 0.001, r = -0.638 vs. P < 0.001, r = -0.446) (for females:LPTS left vs.right hand: P < 0.001, r = 0.618 vs. P < 0.001, r = 0.403). Conclusions: The 2D:4D ratio, an indicator of intrauterine testosterone-estrogen balance, is related to PTS. The effect of testosterone on the growth plate of the proximal tibia may be one of the factors determining the PTS value.

Material and Methods: Between January 2016 and January 2021, 112 ULE patients (67 men, 45 women, mean age 45.55 +/- 10.75 years), 90 BLE patients (47 men, 43 women, mean age 44.93 +/- 9.76 years), and 134 patients determined as the control group (47 men, 43 women, mean age 44.93 +/- 9.76 years) were included in the study. The three groups were compared in terms of vitamin D levels. Results: The mean vitamin D level was 24.87 +/- 8.45 ng/ml in the control group, 16.67 +/- 8.08 ng/ml in the ULE group, and 12.2 +/- 5.71ng/ml in the BLE group. There was a significant difference in vitamin D levels between the control and ULE group, the control and BLE group, and the ULE and BLE group (p<0.001, p<0.001, p=0.014, respectively). Discussion: Vitamin D levels of patients with bilateral lateral epicondylitis were significantly lower than those with unilateral lateral epicondylitis. This study shows that low vitamin D may be one of the etiological factors of lateral epicondylitis and may cause bilateral lateral epicondylitis at lower values.Öğe A new indirect magnetic resonance imaging finding in anterior cruciate ligament injuries: Medial and lateral meniscus posterior base angle(Turkish Joint Diseases Foundation, 2022) Yaka, Haluk; Turkmen, Faik; Ozer, MustafaObjectives: This study aimed to define the medial meniscus posterior base angle (MMPBA) and the lateral meniscus posterior base angle (LMPBA) measured in the medial and lateral meniscus posterior horns and examine the biomechanical and morphological relationship between anterior cruciate ligament (ACL) injuries and posterior meniscus horns using these parameters. Patients and methods: The retrospective study was conducted with 32 patients with ACL rupture and 40 control patients, for a total of 72 patients (40 males, 32 females; mean age: 36.3 +/- 9.9 years; range, 18 to 57 years), between January 2016 and January 2018. The posterior tibial slope (PTS) was measured in standard radiographs, and MMPBA and LMPBA values were assessed by standard knee magnetic resonance imaging. The MMPBA was defined as the angle between the line passing through the medial meniscus' tibial side border and the line passing through the capsular side border in the sagittal section's medial meniscus posterior horn. The LMPBA was defined as the angle between the line passing through the lateral meniscus' tibial side border and the line passing through the capsular side border on the sagittal section's lateral meniscus posterior horn. Groups were compared for PTS, MMPBA, and LMPBA. Results: When both groups were compared in terms of MMPBA and LMPBA, patients with ACL rupture had significantly higher base angles (p<0.001 and p=0.031, respectively). The mean MMPBA was 84.27 degrees +/- 12.59 degrees (range, 62 degrees to 106.1 degrees) in patients with ACL rupture, while it was 70.75 degrees +/- 7.85 degrees (range, 55.1 degrees to 88.6 degrees) in the control group. The mean LMPBA was 83.62 degrees +/- 11.4 degrees (range, 62.3 degrees to 105.9 degrees) in patients with ACL rupture, while it was 76.94 degrees +/- 11.46 degrees (range, 30.8 degrees to 96.5 degrees) in the control group. In the receiver operating characteristics curve analysis, the cut-off value of MMPBA was 84.5, and values above this showed a 58.5% sensitivity and a 97.6% specificity for ACL rupture, whereas for LMPBA, the cut-off value was 93.15, and values above this showed a 27.3% sensitivity and a 95.1% specificity for ACL rupture. The PTS and MMPBA were significantly correlated with each other (p=0.047). The MMPBA and LMPBA were also significantly correlated with each other (p=0.011). However, there was no significant correlation between PTS and LMPBA (p=0.56). Conclusion: Medial meniscus posterior base angle and LMPBA values above 84.5 degrees and 93.15 degrees, respectively, are new indirect magnetic resonance imaging findings of ACL injury.Öğe Radiological Evaluation of Distal Tibiofibular Joint Anatomy Variations in Patients with and Without Syndesmotic Injury(Springer Heidelberg, 2023) Ataoglu, Muhammet Baybars; Tokgoz, Mehmet Ali; Ozer, Mustafa; Kokturk, Anil; Yaka, Haluk; Ergisi, YilmazIntroductionSyndesmosis injuries are a common and debilitating problem affecting the ankle joint, but the precise causes of these injuries remain unclear. In the current retrospective study, it was aimed to investigate the relationship between variations in the distal tibiofibular syndesmosis and surgically proven syndesmosis injuries.Patients and MethodA total of 57 patients with surgically proven syndesmosis injuries and 51 patients without syndesmosis injuries were included as the control group. Computed tomography (CT) scans were used to measure six anatomical features 1 cm proximal to the tibiotalar joint, including the anterior facet length (a), posterior facet length (b), angle between the anterior and posterior facets (c), fibular incisura depth (d), tibia thickness (e), and fibula thickness (f).ResultsComparing the measurements of the patients with and without syndesmosis injury, it was demonstrated that the anterior facet length (a) (p = 0.022) was shorter and the a-b difference (anterior facet length-posterior facet length difference) (p = 0.010) tended toward negative values. Pearson correlation analysis demonstrated that a (r = - 0.211, p < 0.033) and a-b (r = - 0.254, p = 0.010) measurements were strongly negatively correlated with syndesmosis injury.DiscussionOur study findings suggest that the shortness of the anterior facet and the difference in length are related to syndesmosis injuries. To the best of our knowledge, this is the first study to report this relationship with syndesmosis. This study sheds light on the underlying mechanisms of syndesmosis injury, which could help clinicians in the diagnosis, treatment, and prevention of this common ankle injury.Level of evidence: Level 4: case-control study.Öğe The Relationship Between Fibular Notch Anatomy and ATFL Rupture(Elsevier Science Inc, 2023) Yaka, Haluk; Ozer, Mustafa; Turkmen, Faik; Demirel, Ahmet; Kanatli, UlunayThe anterior talofibular ligament (ATFL) is the first to be damaged during a lateral ankle sprain. Dynamic and static structures have been investigated to better understand ATFL rupture, but the predisposing factors have not been fully elucidated. This study aims to define the fibular notch version that can evaluate the position of the fibular notch relative to the tibia and investigate the relationship between the fibular notch version (FNV) and ATFL rupture. This study included 71 patients with isolated ATFL rupture diagnosed clinically and radiologically and 71 control patients without any foot or ankle pathologies. Anterior facet length (AFL), posterior facet length (PFL), anterior-posterior facet angle (APFA), fibular notch depth (ND), and FNV measurements were performed on axial magnetic resonance images (MRI). We defined FNV as a parameter that evaluates the fibular notch's relative position to the distal tibia. The mean FNV was 16.6 & DEG; & PLUSMN; 4.9 & DEG; in patients with ATFL rupture and 12.4 & DEG; & PLUSMN; 5.6 & DEG; in the control group; when both groups were compared, FNV measurements were significantly higher in patients with ATFL rupture (p = .002). The mean APFA was 123.9 & DEG; & PLUSMN; 10 & DEG; in the group with ATFL rupture and 129.7 & DEG; & PLUSMN; 7.8 & DEG; in the control group. When both groups were compared, APFA was significantly lower in patients with ATFL rupture (p = .014). There was no significant difference between the groups regarding AFL, PFL, and ND. A more posterior (retroverted) fibular notch and a lower fibular notch angle seem to be associated with higher rates of ATFL rupture. & COPY; 2023 by the American College of Foot and Ankle Surgeons.
