“…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.

“…Morphometric and morphological characteristics of the FLHOF are essential for the surgical approaches for preservation or reconstruction of the injured LHOF due to its relationship with this ligament (1,2). It has been reported that the relationship between the morphometry of the FLHOF and its position with the development of dysplasia and osteoarthritis in the hip joint (3,4). Morphological features of FLHOF may provide useful information in clinical practice for objective evaluation of DOI: 10.37990/medr.1107706 the hip joint osteoarthritis and LHOF.…”

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 presence of a central femoral osteophyte was defined as > 2 mm [ 19 ]. No size cutoff was used for the remaining osteophytes due to the lack of established criteria.…”

Objectives To identify preoperative degenerative features on traction MR arthrography associated with failure after arthroscopic femoroacetabular impingement (FAI) surgery. Methods Retrospective study including 102 patients (107 hips) undergoing traction magnetic resonance arthrography (MRA) of the hip at 1.5 T and subsequent hip arthroscopic FAI surgery performed (01/2016 to 02/2020) with complete follow-up. Clinical outcomes were assessed using the International Hip Outcome Tool (iHOT-12) score. Clinical endpoint for failure was defined as an iHOT-12 of < 60 points or conversion to total hip arthroplasty. MR images were assessed by two radiologists for presence of 9 degenerative lesions including osseous, chondrolabral/ligamentum teres lesions. Uni- and multivariate Cox regression analysis was performed to assess the association between MRI findings and failure of FAI surgery. Results Of the 107 hips, 27 hips (25%) met at least one endpoint at a mean 3.7 ± 0.9 years follow-up. Osteophytic changes of femur or acetabulum (hazard ratio [HR] 2.5–5.0), acetabular cysts (HR 3.4) and extensive cartilage (HR 5.1) and labral damage (HR 5.5) > 2 h on the clockface were univariate risk factors (all p < 0.05) for failure. Three risk factors for failure were identified in multivariate analysis: Acetabular cartilage damage > 2 h on the clockface (HR 3.2, p = 0.01), central femoral osteophyte (HR 3.1, p = 0.02), and femoral cartilage damage with ligamentum teres damage (HR 3.0, p = 0.04). Conclusion Joint damage detected by preoperative traction MRA is associated with failure 4 years following arthroscopic FAI surgery and yields promise in preoperative risk stratification. Clinical relevance statement Evaluation of negative predictors on preoperative traction MR arthrography holds the potential to improve risk stratification based on the already present joint degeneration ahead of FAI surgery. Key Points • Osteophytes, acetabular cysts, and extensive chondrolabral damage are risk factors for failure of FAI surgery. • Extensive acetabular cartilage damage, central femoral osteophytes, and combined femoral cartilage and ligamentum teres damage represent independent negative predictors. • Survival rates following hip arthroscopy progressively decrease with increasing prevalence of these three degenerative findings.

Osseous spurs at the fovea capitis femoris—a frequent finding in asymptomatic volunteers

Abstract: Smaller osseous spurs (<2 mm) at the border of the fovea capitis femoris are very common in asymptomatic volunteers and do not seem to be pathologic.
