“…Approximately 200,000 of them are those who reside in the UK and the USA. This is a case which negatively affects in the short-term and the long-term success of operations carried out in Asian and African countries owing to morphological incongruity of implant bones, where the proximal femoral morphometry is different from the one in Western countries, except for the Japanese who produce in accordance with their people's proximal femoral morphometry thanks to their highly-developed prosthesis industry (Baharuddin et al, 2011;Murlimanju et al, 2012;Atilla et al, 2007;Hoaglund and Low, 1980; *Correspondence to: Mustafa G€ uvençer, Department of Anatomy, Faculty of Medicine, University of Dokuz Eyl€ ul, Balçova, 35340-Izmir, Turkey.

It is important to know the morphometric characteristics of the proximal femur. This is necessary to reduce the risk of complications related to surgical procedures performed in the area due to vascular, metabolic, or traumatic causes. It is of importance for achieving the alignment of the prosthesis to be implanted as well. The aim of this study was to evaluate the morphometric characteristics of the proximal femur and to establish a database for making and performing total hip prosthesis. Anteroposterior (AP) pelvic radiographs of 162 cases, with a mean age of 65.6 years, who had undergone unilateral total hip arthroplasty were used in this study. Femoral head diameter (FHD), femoral neck width (FNW), femoral neck length (FNL), femoral neck axis length (FNAL), intertrochanteric line length (ILL), and neck-shaft angle (NSA) were measured on radiographs obtained digitally using setrapacs media. FHD was found to be 48.1 ± 3.7 mm, FNW 35.4 ± 4.2 mm, FNL 30.8 ± 6.1 mm, FNAL 98.6 ± 9.4 mm, ILL 81.1 ± 7.9 mm, and NSA 130.4 ± 5.1° on average. The comparison of the mean values for females and males revealed a statistically significant difference between the FHD, FNW, FNL, FNAL, and ILL (P = 0.000). There was no statistically significant difference in NSA between males and females (P = 0.356). A weak correlation was found between age and parameter values using correlation analysis (r < 0.24, P > 0.05). In morphometric assessment of the proximal femur, taking into consideration regional and sexual differences is of importance for prosthesis design and surgical success.

“…Our study showed that Indonesian population has smaller femoral head dimension compared with Western population (Noble et al, 1988;Rubin et al, 1989;Hussmann et al, 1997). However, among southeast Asian, such as Thai and Malaysian, our study showed that Indonesia has larger femoral head morphometry (Baharuddin et al;Mahaisavariya et al, 2002). Extramedullary dimensions (femoral head position, femoral head offset, and ante version angle) play an important role in maintaining proper hip kinematics and it will affect the satisfaction of post-operative result (Sugano et al, 1999;Ranawat & Rodriguez, 1997).…”

“…Differences in genetics, lifestyle, applied force and their distribution affect the build and stature size between ethnicity as shown in several studies (Hoaglund & Low, 1980;Igbigbi & Msamati, 2002;Baharuddin et al, 2011). Based on some studies, it showed that the eastern population has relatively smaller measurement compared with Western population.…”

SUMMARY:To design custom-made prosthesis in a certain population, the morphometry needs to be measured. The results of this study were expected to provide basic data to design the ideal size of the total hip arthoplasty prosthesis for Indonesian population. This was an anthropometric study conducted on sex matched 100 healthy Indonesian mongoloid race subjects based on Computer Tomographic (CT) imaging on the proximal femur. The parameters being used in this study were Femoral Head Offset (FHO), Femoral Head Position (FHP), Femoral Head Diameter (FHD), Neck-Shaft Angle (NSA), Anteroposterior Width (APW) and Mediolateral Width at 3 different locations, and Canal Flare Index (CFI). This study showed that Indonesian has smaller proximal femur morphometry as compared to Western population. The mean value of all parameters in male were larger than female. Moreover, FHO and FHP showed significant difference among male and female indicating the location of male femoral head center lies superiorly as compared to female. The dimension of femoral canal was found to be mediolaterally oval, 1.43, 1.28, and 1,34, respectively, in 3 different cutting (20 mm above and 40 mm below lesser trochanter, and isthmus). CFI of Indonesian was classified to be stovepipe femoral canal (2.99) that is the suggestion to use cemented femoral stem. This study showed that Indonesian proximal femur dimension has smaller build compared with Western counterpart. The proposed dimensions can be used as the basic data to design the ideal size of the femoral stem for Indonesian population.

“…We prospectively acquired the computed tomography (CT) images from 60 healthy hips prior to designing the cementless femoral stem in accordance with the peculiar morphology of the Asian population (13)(14)(15)(16). The design process used a three-dimensional femora model that provides more anthropometric information and accurate measurement.…”

“…The cementless femoral stem was designed to optimally fit and fill the endosteal canal as shown in Fig. The 3D femora model chosen for finite element study was the "average" femora from the previous study (13)(14)(15)(16). Interquartile range descriptive analysis was used as the stem design profile, and nonlinear finite element analysis was conducted to predict the outcome of the early stage after the surgery according to the standard protocol of virtual implantation (2)(3)(4).…”

Total hip arthroplasty is a flourishing orthopedic surgery, generating billions of dollars of revenue. The cost associated with the fabrication of implants has been increasing year by year, and this phenomenon has burdened the patient with extra charges. Consequently, this study will focus on designing an accurate implant via implementing the reverse engineering of three-dimensional morphological study based on a particular population. By using finite element analysis, this study will assist to predict the outcome and could become a useful tool for preclinical testing of newly designed implants. A prototype is then fabricated using 316L stainless steel by applying investment casting techniques that reduce manufacturing cost without jeopardizing implant quality. The finite element analysis showed that the maximum von Mises stress was 66.88MPa proximally with a safety factor of 2.39 against endosteal fracture, and micromotion was 4.73μm, which promotes osseointegration. This method offers a fabrication process of cementless femoral stems with lower cost, subsequently helping patients, particularly those from nondeveloped countries.
