“…Some studies evaluating FCF dimensions have measured the largest diameter of the FCF (TL-FCF) in axial and coronal sections on computed tomography or magnetic resonance images (MRI) [11,12,16]. In asymptomatic volunteers, the width of FCF found by Bensler et al did not contain similar results to our ndings.…”

“…In addition, an excess of nutrient foramina reduces the likelihood of developing osteonecrosis [6]. Hip dysplasia and osteoarthrosis have been related to modi cations in the morphometric structure and location of the FCF in the hip joint [10][11][12]. As the femoral head is supplied by vessels that travel through the FCF, the features of the anatomical structures on the head of the femur are considered potential factors in avascular necrosis.…”

Purpose This study aimed to examine the morphometric properties of the fovea capitis femoris (FCF), including its location on the femoral head, shape varieties, and correlation with gender-specific femoral head parameters. Methods Seventy-two (n = 72) dry femurs were used. The morphometric features of these bones were assessed based on gender. While some of the FCF and femoral head parameters were measured on dry bones using calipers, others were measured using ImageJ software (Version 1.53q) on digital images. Results All parameters were similar in both genders except FHD-V and FHA (p > 0.05). FHD-V and FHA values were higher in males (p < 0.05). Although the mean values of LL-FCF, TL-FCF, A-FCF, and foramina number were higher in females, there was not a significant difference between genders (p > 0.05). Foramina localization was mainly central (51.4%). Five of the femoral heads have no foramina (6.9%). Four types of FCF were identified and most of them were oval type (61.1%). It was found that only 5.6% of FCFs were in the posteroinferior squad, and the vast majority were in posterosuperior squads. Conclusion The findings indicated that a few femoral head parameters were connected to the morphometric traits, localization, and shape types of the FCF. It was noted that there were gender-specific differences in a few parameters. Our research is expected to benefit anthropological sciences, radiological applications, and orthopaedics.

“…Precise information about the position of the fovea is important for radiological evaluation of the images, and to assist diagnostic hip arthroscopic, especially in patients with absent or completely ruptured LHOF (11). Localization of the fovea could provide useful information for the identification of the rotational position of the head of the femur in the fixation approach in femoral neck fractures (5,18).…”

Aim: This study was performed to examine morphometric and morphological characteristics of the fovea capitis femoris (FCF) on the dry femur to determine its location and morphological types. Material and Method: FCF was analyzed morphometrically and morphologically on 58 dry adult femora (27 right; 23 left) and their digital images. Dimensions and surface area of the FCF were measured using a digital caliper on dry bone and ImageJ software on digital images. Results: The transverse length of the FCF (p < 0.001) and surface area of the FCF (p = 0.007) were found to be greater in the left femur bones than in the right femur bones. Type 1 localization was the most common localization type of the FCF. The most common morphological type was found as oval-shaped FCF (43.8%), followed by round (40.4%), triangular (10.5%), and piriform shape types (5.3%). Conclusion: This study indicates that FCF was located mostly posteroinferior quadrant and is usually oval or round in shape. Findings obtained in the present study could provide useful information in both clinical and anthropological practice.

“…The correct position of the lag screw was ensured (Baumgaertner et al, 1995;Kuzyk et al, 2012). Its position was evaluated on AP and axial radiographs by calculating the distance between the intersection of the long axis of the neck with the femoral head cortex on both projections (Ceynowa et al, 2019) and the similar intersection of the long axis of the screw (Lenich et al, 2011).…”

Background: Intertrochanteric fractures may occur in a bone with a wide medullary canal that may lead to significant mobility of a intramedullary nail, contrary to an extramedullary device. This study evaluates the Dynamic Hip Screw and the gamma nail in AO 31.A2.1 fractures in these circumstances. Methods: Synthetic femora with canals drilled to 18 mm were used. Five fixation types were examined: a 2-hole and a 4-hole Dynamic Hip Screw with a 2-hole plate, a standard gamma nail with dynamic and static distal locking and a long gamma nail. The specimens were tested with cyclic axial loading, from 500 N increasing of 50 N increments in each cycle. Force at failure, overall stiffness, stiffness at the fracture site, location and mode of failure were recorded. Findings: The short gamma nails dislocated into varus under preload because the nail migrated laterally. The Dynamic Hip Screw was initially stable, but some specimens rotated around the lag screw. The gamma nail was rotationally stable. Both implants failed through femur fracture. The long gamma nailed failed by screw cutout at forces lower than the ultimate force of the short gamma nail. Interpretation: This study shows that the gamma nail is unstable in a large medullary canal but offers better rotational stability of the proximal fragment. A modification of the nail design or the operative technique may be considered.

The position and morphometry of the fovea capitis femoris in computed tomography of the hip

Abstract: The femoral neck axis in the transverse plane always crosses the anterior aspect of the fovea. Its position is unrelated to the angular geometry of the proximal femur, but related to the femoral head size. It is found to be relatively larger in women.
