Rezumat

In the last years, the number of diagnostic procedures and surgical interventions performed at the hip joint level have increased considerably. This requires the continuous study of the morphological aspect and of the vascularization variants of the hip joint. The majority of the blood supply to the head of the femur comes from the medial and lateral circumfle branches of the profunda femoris, which itself is a branch of the femoral artery. The MCFA and LCFA make an anastomose, to form a ring around the neck of the femur, from which many small arteries branch off to perfuse the femoral head. The purpose of the research was to find scientific information from international literature. The PubMed, Web of Science, Scopus, database was used to identify specific articles which has tangency with current research. The articles from last twenty years were analyzed and were identified the main sources of the vascularization of the hip joint. The following search terms were used: femoral head circulation, femoral head blood supply, femoral neck circulation, femoral neck blood supply, superior gluteal artery, inferior gluteal artery, medial femoral circumflex artery, lateral femoral circumflex artery, superficial femoral artery, posterior superior nutrient artery, posterior inferior nutrient artery and profunda femoris.All data was pooled into a meta-analysis using MetaXL v2.0. A total of 12 (10 cadaveric and 2 imaging) studies (n = 1052 lower limbs) were included into the meta-analysis. The pooled prevalence of the MCFA originating from the DFA was 74.7% (97% CI [70.0–81.5]), while the pooled prevalence of the MCFA originating from the CFA was 42.8% (92% CI [27.7–41.1]). The CFA-derived MCFA was found to originate as a single branch in 85.1% (95% CI [72.1–93.7]) of cases with a mean pooled distance of 50.14 mm (95% CI [42.50–57.78]) from the MIP. In 98,3% cases, it was present the articular branch for the hip joint.The prevalence of the LCFA originating from DFA, CFA, SFA artery was 97.42%, 2.06%, and 0.52%, respectively. It was evidenced, the presence of the articular branch for the hip joint, in 90,1%. The superior gluteal artery gives articular branch in 99,4%. Knowing these anatomical structures can bring an important information to surgeons, especially during orthopedi interventions in the region of the hip joint, in which improperly conducted procedures may lead to injury of the MCFAand LCFA with subsequent avascular necrosis of the femoral head.
