Therefore, if the anterior approach was used, it would destroy the left blood supply of femoral head because the ascending branch of lateral femoral circumflex
artery and anterior capsular must be cut by this approach.
Computed tomography angiography revealed active bleeding from the ascending and descending branches of lateral femoral circumflex artery.
CTA revealed active contrast extravasation from the ascending and descending branches of lateral femoral circumflex artery (LFCA), which arises from the PFA [Figure 3].
The femoral head has an inherently vulnerable blood supply due to its natural course (20) It is fed by a different vessels, predominantly by branches of the medial and lateral femoral circumflex
arteries that encircles the femoral head in the trochanteric area and branch off into retinacular vessels that pass proximally toward the head in three segments: small anterior, posteroinferior and posterosuperior retinacular arteries.
Different from femoral neck fractures in elderly patients, because of strong external force with severe damaging of medial femoral circumflex artery and lateral femoral circumflex artery, young adults are more likely to develop to nonunion and ANFH.
Shift pedicled iliac bone with ascending branch of lateral femoral circumflex artery in treatment of femoral neck fractures in young adults (in Chinese).
The cruciate anastomosis involves the inferior gluteal, medial femoral circumflex, lateral femoral circumflex
and the first perforating branch of the profunda femoral arteries.
This ring is formed predominantly by contributions from the medial femoral circumflex artery posteriorly, with smaller contributions from the lateral femoral circumflex
