ABSTRACT
Femoroacetabular impingement syndrome (FAI) is a clinical entity that has been recognized in recent years as a frequent cause of pain and the early development of hip arthrosis. Subspine hip impingement is characterized by the prominent or abnormal morphology of the anteroinferior iliac spine (AIIS), which contributes to the development of a clinical picture that is similar to FAI. The aims of this study were to propose a new morphological classification of the AIIS, to determine the prevalence of the different AIIS morphologies based on this classification and to correlate the presence of said morphologies with different gender and age groups. The sample consisted of 458 hemipelvises from individuals of known age and sex (264 men and 194 women). Each specimen was analyzed to determine the prevalence of each of the different morphologies of the AIIS based on the classification proposed as Type 1: the presence of a concave surface between the AIIS and the acetabular rim; Type 2A: the presence of a flat surface between the AIIS and the acetabular rim; Type 2B the presence of a convex surface between the AIIS and the acetabular rim; and Type 3: the AIIS protrudes inferiorly toward the anterior acetabulum. A prevalence of 69.87% was determined for Type 1 AIIS (320/458). In regard to abnormal morphology, prevalences of 17.90% (82/458), 3.71% (17/458) and 8.52% (39/458) were determined for type 2A, Type 2B and Type 3, respectively. The prevalence of abnormal AIIS morphology was 30.30% (80/264) in male specimens and 29.90% (58/194) in female specimens. This study demonstrates the prevalence of the different morphologies of the AIIS, providing information that will be useful in determining the role of the AIIS in the emergence of subspine hip impingement.
El Síndrome de Pinzamiento Femoroacetabular (PFA) es una entidad clínica reconocida en los últimos años como una causa de dolor y desarrollo de artrosis temprana de cadera. El pinzamiento subespinoso de la cadera se caracteriza por una espina iliaca anteroinferior (EIAI) prominente o con una morfología anormal, lo que contribuye al desarrollo de un cuadro clínico similar al PFA. El objetivo fue proponer una nueva clasificación morfológica de la EIAI y determinar las prevalencias de las distintas morfologías de la EIAI en base a la misma y correlacionarla con los distintos sexos y grupos de edad. La muestra consistió en un total de 458 hemipelvis, de sexo y edad conocidos (264 hombres y 194 mujeres). Cada pieza fue analizada para determinar la prevalencia de variaciones morfológicas de la EIAI en base a la clasificación propuesta. Tipo 1: presencia de una superficie cóncava entre la EIAI y reborde acetabular, Tipo 2A: presencia de una superficie plana entre la EIAI y el reborde acetabular, Tipo 2B: presencia de una superficie convexa entre la EIAI y el reborde acetabular y Tipo 3: la EIAI protruye hacia el acetábulo anterior o inferiormente. Se determinó una prevalencia de 69,87% para la EIAI Tipo 1 (320/458). En cuanto a las morfologías anormales, se determinó una prevalencia de 17,90% (82/458), 3,71% (17/458) y 8,52% (39/459) para los Tipos 2A, 2B y 3, respectivamente. La prevalencia de una morfología anormal en las EIAI de especímenes del sexo masculino fue de 30,30% (80/264) y en el sexo femenino 29,90% (58/194). Se evidencia la prevalencia de las diferentes morfologías que puede tener la EIAI; esta información será de ayuda para determinar el papel de la EIAI en la aparición del pinzamiento subespinoso de la cadera.

Autogenous tricortical iliac crest bone graft is the most widely used for the anterior cervical interbody fusion procedure. The authors performed systematic measurements to delineate the thickest areas of the iliac crest, so that surgeons would know where to select the appropriate grafts for cervical interbody fusion. The Department of Anatomy, Faculty of Medicine, Khon Kaen University, supplied 232 iliac crests (116 left; 116 right) dried hip bones donated by 67 Thai males and 49 Thai females. The deceased averaged 59 years of age (range, 26-86). The thickest part of the iliac crest extended from 3 to 5 cm posterior to the ASIS and ranged between 15.59 and 17.02 mm. These regions have an appropriate thickness for harvesting graft material.

The findings indicate that sexual maturity would be initiated only after the attainment of requisite morphological body size such as weight on an average nearly 27 kg and height of 137 cm, irrespective of age and SES. The girls from LSES were chronologically older throughout the span of pubertal growth. However, they took lesser time to reach full maturity after the attainment of mid-pubertal growth compared to USES. Menarche appeared after attaining about a minimum weight of 35 kg, height of 143 cm and bicristal breadth is 24 cm. Its appearance followed the attainment of peak height velocity and 3rd developmental stage of breast and/or pubic hair. It, however preceded the attainment of weight and bicristal breadth peak velocities.
