The spelling of the medical term "articulation sacroiliaca" can be explained using IPA phonetic transcription. The word is pronounced /ɑːtɪkjʊˈleɪʃən sækroʊɪliˈækə/. The first part of the word "articulation" is pronounced with the "ar" sound as in "car," followed by the "ti" sound as in "nation" and the "u" sound as in "up." The second part of the word "sacroiliaca" is pronounced with the "a" sound as in "bat," followed by the "cr" sound as in "crumb," and finally the "i" sound as in "ill" and "a" as in "cat."
Articulación sacroilíaca is a Spanish term that translates to "sacroiliac joint" in English. It refers to the joint formed by the articulation of the sacrum and the ilium, specifically between the triangular bone at the base of the spine and the pelvic bone. The sacroiliac joint is located on either side of the vertebral column, joining the sacrum to the pelvis, and is considered a strong and weight-bearing synovial joint.
The primary function of the sacroiliac joint is to provide stability and transmit forces between the lower extremities and the axial skeleton. It plays a crucial role in the transfer of the compressive loads from the upper body to the lower limbs, as well as in shock absorption during physical activities.
The sacroiliac joint is supported by a network of ligaments, which provide additional stability. These ligaments include the anterior and posterior sacroiliac ligaments, the interosseous sacroiliac ligament, and the sacrospinous and sacrotuberous ligaments. Their combined action helps to maintain the alignment and integrity of the joint.
Disorders of the sacroiliac joint can lead to pain and dysfunction in the lower back, hip, and buttock regions. Conditions such as sacroiliitis, inflammation of the sacroiliac joint, and sacroiliac joint dysfunction can result in discomfort and limited mobility. Treatment options for sacroiliac joint-related issues may include physical therapy, medications, injections, and in some cases, surgical interventions.

The etymology of the term "articulatio sacroiliaca" comes from Latin.
1. "Articulatio" is derived from the Latin word "artus" meaning "joint" and "-tio" is a suffix indicating a condition or state. Therefore, "articulatio" refers to a joint or the act of joining.
2. "Sacroiliaca" is a combination of two Latin words: "sacrum" meaning "sacrum" (the triangular bone at the base of the spine) and "iliaca" meaning "ilium" (the large, flaring bone forming the upper part of the pelvis).
Therefore, "articulation sacroiliaca" refers to the joint between the sacrum and the ilium.
