“…Proximal femoral anatomy has been the subject of numerous studies owing to the success of hip arthroplasty worldwide [5,6,15,18,31,43], and as a result of the discovery that certain femoral disorders, such as femoral acetabular impingement and Legg-Calvé-Perthes disease, can lead to osteoarthritis [1,11,13,41]. The investigators who have examined symmetry have studied bone properties and cortex thickness [28,32,36,40], with few studying dimensions [3,28].…”

“…Research on gender anatomic variations showed differences in femoral offsets and canal dimensions between males and females [2,6,29,44]. Studies of ethnic variations of morphologic features of the femur showed differences in femoral head diameters, femoral offset, and shaft diameters between European and Asian populations [18,43]. Research on bilateral femoral asymmetry has focused on properties such as bone mineral density, mechanical strength, cortex thickness, torsion angles, limb lengths, or the distal femur [8,26,28,32,36,40].…”

Background The contralateral femur frequently is used for preoperative templating for THA or hemiarthroplasty when the proximal femur is deformed by degenerative changes or fracture. Although femoral symmetry is assumed in these situations, it is unclear to what degree the contralateral femur is symmetrical. Questions/purpose We therefore defined the degree of asymmetry between left and right proximal femurs and determined whether it was affected by demographics and proximal femoral anatomy. Methods We obtained 160 paired femurs from individuals (20-40 years old), evenly distributed for gender and ethnicity (African-American and Caucasian). The height and weight of the individuals were recorded. We measured the femoral head diameter, minimal femoral neck diameter in the AP and cephalocaudal (CC) planes, and the AP femoral diaphyseal diameter. The absolute and percent differences were determined.Results All femoral measurements showed an absolute difference less than 2 mm and a percent asymmetry and difference less than 2% for the femoral head, less than 4% for the femoral neck, and less than 3.5% for the femoral shaft. We found no correlation or predictive value between absolute differences and asymmetry and age, ethnicity, gender, or weight. Height was negatively associated with femoral head differences and thus increased symmetry of the femoral head. Conclusions Our data support assumptions of substantial symmetry of the proximal femur and highlights that asymmetry is not affected by demographics or the size of the proximal femur. Asymmetry tends not to occur in isolated segments of the femur.

“…First and foremost is the difference of the anthropometry of the proximal femur between ethnics due to differences in lifestyle, physique, applied force and their distribution. This can be seen from numerous data presented in various studies for the western and eastern population (Hoaglund & Low, 1980;Gnudi et al, 2004;Calis et al, 2004;Igbigbi & Msamati, 2002;Mahaisavariya et al, 2002;De Sousa et al, 2010;Mishra et al, 2009;Caetano et al, 2007;Da Silva et al, 2003). Another issue is implant-morphology mismatch that might cause difficulties during implant placement and could lead to accelerated deterioration of the implant life thus affecting short-term and long-term outcome of the surgery (Reddy et al, 1999;Noble et al, 1988;Kaya et al, 2008;Fang et al, 2010;Ohsawa et al, 1998).…”

SUMMARY:Clinical practice in our country showed a lack of suitable implants that perfectly match the anthropometry of the local population. However, there have been no reports or comprehensive studies conducted to substantiate this argument. We therefore prospectively studied 120 hips from sixty subjects with an average age of 25±5.18 years old. The average weight and height were 61.48±13.84 kg and 1.65±9.63 m respectively. The exclusion criteria were pregnant woman, those who had injury to the hip joint, and those with implant or prosthesis. Four parameters were measured -the femoral head diameter (FHD), femoral neck length (FNL), femoral neck width (FNW) and collo-diaphyseal angle (CDA). Statistical analysis showed no significant differences between left and right femora but significant differences were found between male and female subjects. The results for the male and female femurs are as follows -FHD: 43.6±3.1 mm and 38.9±2.2 mm; FNL: 91.1±5.7 mm and 81.8±4.3 mm; FNW: 28.9±3.4 mm and 26.0±4.3 mm; CDA: 132.3°±3.4° and 129.9°±4.0°. This data could be used as a guideline to design a more suitable implant for the Malay population which covers most of the South East Asian countries.
