AP radiograph of the right hip of a 50-year-old woman, demonstrating classic characteristics of acetabular dysplasia. FIGURE 3.29. AP radiograph of the right hip of a 24-year-old woman with mechanical catching, suggestive of labral pathology. Signs of mild dysplasia include a slight valgus position of the femoral neck and slight lateral uncovering of...

Vascular Supply To The Femoral Head

Ligamentum Teres Hip

Intraarticular isolation of the femoral head and neck makes it highly dependent on its tenuous vascular supply. Its susceptibility to circulatory compromise is an ongoing source of concern to physicians who treat hip pathology. Ischemic insult followed by avascular necrosis AVN of the femoral head, similar to other forms of osteonecrosis, has been clearly linked to certain disease states and types of exposure although it is less clearly associated with others and often purely idiopathic.10 AVN...

Capsular and joint architecture

Femoral Attachment The Etabulum

The ilium, ischium, and pubic bones unite at the acetabulum, forming the innominate bone. During childhood, these bones are separated within the ac-etabulum by the triradiate cartilage, which fuses at skeletal maturity. The acetabulum has an inclined abduction angle of approximately 35 degrees from the horizontal and a forward flexed position of approximately 20 degrees Figure 6.8A,C . The articular surface of the acetabulum has a horseshoe or lunate shape Figure 6.9 . The central inferior...

Obturator Nerve Entrapment Description

Femoral Nerve Thickening

Chronic groin pain is a difficult problem to evaluate. The differential diagnosis for groin symptoms is broad and may include gynecologic, urologic, and colorectal diseases. Moreover, neuropathies of the cutaneous nerves around the hip have been highlighted as etio-logic factors for groin pain.35,37 Nonetheless, the information on this topic is sparse, partly because these injuries are rare. The literature on groin pain of neural origin has mainly focused on the genitofemoral, lateral femoral...

Neurovascular Structures

Lateral Femoral Circumflex Artery

The femoral neurovascular structures (nerve, artery, and vein) exit the pelvis under the inguinal ligament halfway between the anterior superior iliac spine and the pubic tubercle (Figure 6.6). They are relatively anterior to the hip joint, with the nerve being the most lateral. These structures lie on the anterior surface of the iliopsoas muscle, and thus the muscle separates the femoral neurovascular structures from the hip. The lateral femoral cutaneous nerve originates from the lumbar...
