“…The mean FNA angle in the female group was 17.1 ± 9.9 and in male group was 10.6 ± 8.3. Our study results support the current literature in terms of gender-specific differences of FNA [3,7]. FNA is important for the reconstruction of native hip biomechanics in hip joint arthroplasty procedures.…”

“…Understanding the racial differences in the native 3D femoral anatomy is important for an accurate preoperative planning and designing more compatible orthopedic implants [1,6,7]. In the literature, there are many studies that investigate the femoral anatomical features of different populations [1][2][3][4][5]7,10]. Most of these studies, that analyzed the racial differences on anatomical features, have focused on the Caucasian population from western countries [2][3][4][5]; however, the studies investigating the native femoral anatomy of the populations originated from different races on 3D models are limited [7,10].…”

“…Nowadays, the two-dimensional (2D) tomography images could be converted into the three-dimensional (3D) models using specialized imaging programs. 3D modelling, which have an increasing interest in the literature, that could help the surgeons to better understand the lesions by visualizing the real anatomical features compared to plain radiographs and 2D tomography images [7][8][9].…”

“…Gender effects on native femoral anatomy is especially important for the development of suitable implants and prosthesis. Implant modifications and optimizations, which are made in accordance with genderspecific anatomical differences, could increase the postoperative functional results [7]. The effects of gender, age and race on anatomical features using the tomographic measurements, were largely investigated in the literature [1,3,4,[8][9][10].…”

IntroductionThree-dimensional (3D) modelling, which has an increasing interest in the literature, could help surgeons to better understand the lesions by visualizing the real anatomical features compared to plain radiographs and two-dimensional (2D) tomography images. We aimed to evaluate the native femoral anatomical features of Turkish females and males using 3D computed tomography models. MethodsWe evaluated the right femoral anatomical features of 60 females and 60 males between 31 and 65 years of age creating 3D computerized tomography models. The gender-specific differences of femoral neck inclination and anteversion, femoral mechanical-anatomical axis, anatomical and mechanical lateral distal femoral, medial and lateral proximal femoral angles were measured on 3D femoral anatomical models. ResultsThe mean age of our study groups was 50.6 ± 8.5. We determined a statistically significant difference between gender groups in terms of mean femoral neck anteversion angles (p = 0.009). We observed the retroversion of the femoral neck in 12 adults (10%). The mean values of femoral neck inclination, femoral mechanical -anatomical angle, anatomical and mechanical lateral distal femoral angles, medial and lateral proximal femoral angles did not differ any statistical significance between gender groups. ConclusionAlthough the anatomical angle measurements except femoral neck anteversion, did not differ significantly between gender groups of our study, there were differences between mean anatomical angles when compared to other studies in the literature, which investigate the different races or Caucasian population. Through 3D anatomical data, more compatible implants, prosthesis or biomaterials can be produced by determining gender and race-specific anatomical differences.

Fractures are difficult to treat because of individual differences in bone morphology and fracture types. Compared to serialized bone plates, the use of customized plates significantly improves the fracture healing process. However, designing custom plates often requires the extraction of skeletal morphology, which is a complex and time-consuming procedure. This study proposes a method for extracting bone morphological features to facilitate customized plate designs. The customized plate design involves three major steps: extracting the morphological features of the bone, representing the undersurface features of the plate, and constructing the customized plate. Among these steps, constructing the undersurface feature involves integrating a group of bone features with different anatomical morphologies into a semantic feature parameter set of the plate feature. The undersurface feature encapsulates the plate and bone features into a highly cohesive generic feature and then establishes an internal correlation between the plate and bone features. Using the femoral plate as an example, we further examined the validity and feasibility of the proposed method. The experimental results demonstrate that the proposed method improves the convenience of redesign through the intuitive editing of semantic parameters. In addition, the proposed method significantly improves the design efficiency and reduces the required design time.
