Adductors Muscle [Desktop]
Adductor longus, groin strain, hip biomechanics, Core stability, Hockey groin syndrome. 1. Introduction The adductor group of the proximal thigh is often overlooked in favor of larger, more superficial muscles such as the quadriceps and hamstrings. However, these five muscles (pectineus, adductor brevis, adductor longus, adductor magnus, and gracilis) serve as the primary stabilizers of the pubic symphysis and the hip joint in the frontal plane. In sports requiring rapid changes of direction (e.g., soccer, ice hockey, basketball), adductor strains account for 10-20% of all lower extremity injuries (Werner, 2019).

[Your Name/Student Name] Course: Advanced Musculoskeletal Anatomy / Biomechanics Date: [Current Date] Abstract Background: The adductor muscles of the hip are a complex group of five muscles essential for lower extremity stability, gait, and athletic performance. Despite their common colloquial reference as "groin muscles," their individual anatomical distinctions and synergistic roles are often underappreciated in clinical settings. Objective: This paper provides a comprehensive review of the adductor magnus, longus, brevis, pectineus, and gracilis, focusing on their detailed morphology, biomechanical function during the gait cycle, and the pathophysiology of common injuries. Findings: The adductor magnus acts as a powerful hip extensor in addition to its adductor role, bridging the gap between the adductor and hamstring groups. Adductor-related groin pain is frequently due to eccentric overload, particularly at the musculotendinous junction of the adductor longus. Chronic weakness in this group is linked to altered frontal plane pelvic control and an increased risk of knee injuries like ACL rupture. Conclusion: A nuanced understanding of the adductors—beyond simple hip adduction—is critical for accurate diagnosis, effective rehabilitation, and injury prevention in sports medicine. and Clinical Relevance in Groin Pathology
