Articulação sacroilíaca: relato de caso de uma alteração Morfológica

Abstract

Introduction: The sacroiliac joint is a joint formed by the junction of the sacrum, which is the base of the spine, and the hip bones. Although it is a joint with limited movement, it plays a fundamental role in transmitting forces between the upper body and the lower limbs. Its stability is crucial for supporting body weight, and its morphology and variations can significantly influence both the mobility and functionality of the human body. Objective: The present work aimed to report the morphological changes found in a sacroiliac joint. Method: This is a case report, descriptive, with a qualitative approach of a male bone belonging to the osteological collection of the Paraibano Laboratory of Forensic Osteology (LAPOF) at UFPB. Results and discussion: An ankylosis process was observed in the sacroiliac joint, with evident areas of synostosis. Sacroiliac ankylosis is a condition characterized by the abnormal fusion of the sacroiliac joint surfaces, which can occur as a result of chronic inflammation and is commonly associated with autoimmune diseases. The joint space between the bones reduces or disappears completely due to the formation of bone tissue in the area, limiting the normal movements of the joint. Sacroiliac ankylosis can lead to significant loss of mobility and result in chronic pain, making it difficult to perform daily activities. Conclusion: This study addressed a condition of great clinical relevance, given its ability to affect the biomechanics of the pelvis and the functional impact on patients. The anatomy of the sacriiliac joint plays a crucial role in understanding the mechanisms of injury, and in the therapeutic approach to this condition.
