Accessory obturator nerve articular branch

The **accessory obturator nerve** is a small, variable nerve present in approximately 29% of individuals, arising from the lumbar plexus (L3–L4). It runs along the medial border of the psoas major muscle, passes over the superior pubic ramus, and typically supplies the pectineus muscle and the hip joint capsule through its articular branches. The articular branches from this nerve occasionally provide sensory innervation to the hip joint, sometimes communicating with branches of the obturator or femoral nerves. The presence, course, and branching pattern of this nerve are highly variable, and it is primarily relevant anatomically rather than as a recognized molecular or pharmacological target. Its clinical significance lies in anatomical variation important for surgical planning and for understanding rare causes of neuropathy or hip pain[4][7]. **Key clarifications:** - This entry is not considered a molecular therapeutic target such as a receptor, enzyme, or transporter. It refers to a branch of a peripheral nerve, not a molecule, protein, or canonical drug target. - The precise term “Accessory obturator nerves articular branches” is noncanonical and could refer to small branches supplying the hip joint capsule, but this is best specified as “Accessory obturator nerve articular branch.” - Because this is an anatomical structure (nervous branch) and not a discrete molecular entity, nearly all fields related to drug targeting, biomarkers, and molecular interactions are not applicable.
