“…Most of these morphometric parameters are similar to the findings in a cross-sectional study done in a tertiary hospital in Nepal. 11 The findings are also similar to that of a study done in Turkish population by Iyam C et al 13 However in the South Indian population, FNL and CDA were larger than in our study in an observational study done in cadaveric dry femur. 19 FNW and FNL in our study was larger than that found in a prospective study done in the Malay population while CDA was comparable.…”

“…Iyam C et al reported a statistically significant difference in other parameters as well (FNL, FAL) in the Turkish population, which was not found in our study. 13 Baharuddin MY et al also reported a statistically significant difference in various parameters (FNW, FNL, CDA) between males and females in Malay population, with all parameters being larger among males. 20 In our study proximal femoral morphometry did not show any association with the BMI.…”

“…The sample size was calculated based a pervious study done by Iyem C et al where femoral neck width (FNW) was 35.4 ± 4.2 mm. 13 Considering 95% confidence interval and 2.5% of relative precision on mean, the sample size was determined using one sample formula as-n = (Z²σ²)/ L² = (1.96 × 4.2)² / 0.9² = 83.66 ≈ 84. Thus, a total of 84 patients with a hip fracture admitted in the Department of Orthopedics, were recruited based on purposive sampling technique.…”

Background: Most of the proximal femur fractures are managed surgically by internal fiation with a variety of implants. Improperly designed or ill-fited implant may lead to a failure of fiation, breakage of implant and nonunion, thus increasing the morbidity and the cost of treatment. This study was conducted to evaluate the radiographic morphometry of the proximal femur which may be helpful in designing the implants for the Nepalese population. Methods: In this cross-sectional study, 84 patients aged 18 years and above with traumatic unilateral hip fracture were enrolled. Anthropometric measurements were recorded. The postoperative check X-ray in the antero-posterior view of the pelvis and bilateral hip were assessed. Various morphometric parameters of the proximal femur were measured and recorded in the radiograph of the unaffcted limb using a digital caliper. Results: Out of 84 patients, 47 were male. The mean ± SD femoral neck width, femoral neck length, femoral axis length, cervico-diaphyseal angle, acetabular tear-drop distance, and great trochanter-pubic symphysis distance were 36.10 ± 5.67 mm, 28.29 ± 4.18 mm, 104.51 ± 9.56 mm, 130.35 ± 8.67°, 32.56 ± 11.05 mm, and 163.07 ± 10.71 mm respectively. The femoral neck width was found to be signifiantly larger in males (39.08 ± 3.06 mm) than in females (32.32 ± 5.99 mm, p < 0.001). Conclusion: This study determined the radiographic measurement of the proximal femur and found that the femoral neck width of the males was larger than that of the females.

“…This is in contrast to previous anatomical studies that have focused on open surgical or arthroplasty techniques. 10 – 12 , 22 , 26 The vastus tubercle has recently been qualitatively reported as a reference point for evaluation of peritrochanteric pathology. 29 The presence of the shiny white fibers of the vastus lateralis in direct continuity with this bony prominence provides a distinct and reliable reference point.…”

Background:Hip endoscopy facilitates the treatment of extra-articular disorders of the proximal femur. Unfortunately, current knowledge of proximal femur anatomy is limited to qualitative descriptions and lacks surgically relevant landmarks.Purpose:To provide a quantitative and qualitative analysis of proximal femur anatomy in reference to surgically relevant bony landmarks.Study Design:Descriptive laboratory study.Methods:Fourteen cadaveric hemipelvises were dissected. A coordinate measuring device measured dimensions and interrelationships of the gluteal muscles, hip external rotators, pectineus, iliopsoas, and joint capsule in reference to osseous landmarks.Results:The vastus tubercle, superomedial border of the greater trochanter, and femoral head-neck junction were distinct and reliable osseous landmarks. The anteroinferior tip of the vastus tubercle was 17.1 mm (95% CI: 14.5, 19.8 mm) anteroinferior to the center of the gluteus medius lateral insertional footprint and was 22.9 mm (95% CI: 20.1, 25.7 mm) inferolateral to the center of the gluteus minimus insertional footprint. The insertions of the piriformis, conjoint tendon of the hip (superior gemellus, obturator internus, and inferior gemellus), and obturator externus were identified relative to the superomedial border of the greater trochanter. The relationship of the aforementioned footprints were 49% (95% CI: 43%, 54%), 42% (95% CI: 33%, 50%), and 64% (95% CI: 59%, 69%) from the anterior (0%) to posterior (100%) margins of the superomedial border of the greater trochanter, respectively. The hip joint capsule attached distally on the proximal femur 18.2 mm (95% CI: 14.2, 22.2 mm) from the head-neck junction medially on average.Conclusion:The vastus tubercle, superomedial border of the greater trochanter, and the femoral head-neck junction were reliable osseous landmarks for the identification of the tendinous and hip capsular insertions on the proximal femur. Knowledge of the interrelationships between these structures is essential for endoscopic navigation and anatomic surgical repair and reconstruction.Clinical Relevance:The qualitative and quantitative clinically relevant anatomic data presented here will aid in the diagnosis of proximal femur pathology and will provide a template for anatomic repair or reconstruction.

“…The morphometry consisted of the following parameters: DFH -diameter of the femoral head in the cranio caudal axis (distance in a straight line from the upper end to the lower end of the femoral head) and sagittal axis (distance in a straight line from the front end behind end of the femoral head); DFN -diameter of the femoral neck in a cranio caudal axis (distance in a straight line from the upper end to the lower end of the anatomical neck of the femur) and sagittal axis (distance in a straight line, the front end to the rear end of the lap anatomy of the femur); LFN-length of the femoral neck (distance in a straight line between the lower region of the femoral head and the base of the greater trochanter) and LIL -length of the intertrochanteric line (distance in a straight line joining the highest point of trochanters highest and lowest previously (Mourao & Vasconcellos; Murlimanju et al;Iyem et al, 2013). Initially, the samples were measured with the aid of the caliper ( Fig.…”

SUMMARY:It is important and necessary to know the morphometric characteristics of the proximal femur in order to reduce the risk of complications associated with surgical procedures performed in the area due to vascular, metabolic or trauma causes, and to achieve an alignment of prosthesis to be implanted. The morphometric analysis has proved possible to be used, and can be a valid help to obtain certain parameters that may contribute to scientific research in several areas. For this, a good understanding of evaluation techniques and principles that can be applied to obtain reliable and valid results is needed. To measure the proximal femoral epiphysis by manual morphometry, with the aid of the caliper, and digital morphometry, with the aid of software and compare them. Twenty nine femurs were used to measure the following parameters: diameter of the femoral head in the cranio caudal axis (DFH-CC) and sagittal axis (DFH-S), diameter of the femoral neck cranio caudal axis (DFN-CC) and sagittal axis (DFN-S), length of the femoral neck (LFN) and length of the intertrochanteric line (LIL). After the measurements, the mean values were compared between the two morphometric techniques. The manual morphometry obtained the following average values: DFH-CC 4.42±0.44, DFH-S 4.38±0.47; DFN-CC 3.10±0.35; DFN-S 2.50±0.37; LFN 2.55±0.42; LIL 4.79±0.62. While the values obtained by digital morphometry were: DFH-CC 3.09±0.41, DFH-S 3.35±0.40; DFN-CC 1.79±0.26; DFN-S 2.26±0.23; LFN 1.42±0.33; LIL 3.33±0.54. All parameters measured from the manual technique showed values significantly higher (p<0.05) than values obtained by digital morphometry. This study showed that there is no morphometry gold standard. Different morphometric methods can effectively reproduce, the values of morphometric anatomical structures, depending on the purpose of the study, the anatomical structures and experience of the researcher.
