Abstract

PURPOSE:

This study aimed to define the footprint of the direct and reflected heads of the rectus femoris and the relation of the anterior inferior iliac spine (AIIS) to adjacent neurovascular (lateral circumflex femoral artery and femoral nerve), bony (anterior superior iliac spine [ASIS]), and tendinous structures (iliopsoas).

METHODS:

Twelve fresh-frozen cadaveric hip joints from 6 cadavers, average age of 44.5 (±9.9) years, were carefully dissected of skin and fascia to expose the muscular, capsular, and bony structures of the anterior hip and pelvis. Using digital calipers, measurements were taken of the footprint of the rectus femoris on the AIIS, superior-lateral acetabulum and hip capsule, and adjacent anatomic structures.

RESULTS:

The average dimensions of the footprint of the direct head of the rectus femoris were 13.4 mm (±1.7) × 26.0 mm (±4.1), whereas the dimensions of the reflected head footprint were 47.7 mm (±4.4) × 16.8 mm (±2.2). Important anatomic structures, including the femoral nerve, psoas tendon, and lateral circumflex femoral artery, were noted in proximity to the AIIS. The neurovascular structure closest to the AIIS was the femoral nerve (20.8 ± 3.4 mm).

CONCLUSIONS:

The rectus femoris direct and reflected heads originate over a broad area of the anterolateral pelvis and are in close proximity to critical neurovascular structures, and care must be taken to avoid them during hip arthroscopy.

CLINICAL RELEVANCE:

A thorough knowledge of the anatomy of the proximal rectus femoris is valuable for any surgical exposure of the anterior hip joint, particularly arthroscopic subspine decompression and open femoroacetabular impingement (FAI) surgery.

Origen de la porción directa y refleja del recto anterior

Este estudio proporciona información valiosa sobre la relación de la Espina Iliaca Anteroinferior (EIAI) y el tendón del recto anterior con las estructuras críticas mediales de la cadera y la pelvis, incluyendo el paquete vasculonervioso femoral. Los datos indican que en la mayoría de los casos el nervio femoral pasa aproximadamente 2cm medial de la EIAI, y la cavidad pélvica se encuentra inmediatamente medial a la EIAI.
Este estudio también confirmó la hipótesis del autor de que las porciones directa y refleja del recto femoral se originan en una amplia zona de la pelvis anterior y lateral y muy próximas a las estructuras tendinosas y neurovasculares. El hallazgo de un origen amplio muestra que un conocimiento profundo de la anatomía de l parte proximal del recto femoral y del paquete neurovascular femoral en particular, es valioso para cualquier tratamiento de la parte anterior de la articulación de la cadera.
Las dimensiones medias de la porción directa del recto anterior fueron 13,4 (medial-lateral) y 26,0 mm (cráneo-caudal). En contraste, las dimensiones medias de la porción refleja fueron 47,7 (anteroposterior) y 16,8 mm (cráneo-caudal). La huella fue ligeramente menor en las mujeres (directa, 11,4 23,8 mm; refleja, 44.3 16.9 mm) que en los varones (directa, 14,4 27,1 mm; refleja, 49.4 16.8 mm).
