By continuing we’ll assume you’re on board with our cookie policy. There are 31 pairs of spinal nerves each contributing to the innervations of many muscles (e.g. The hip adductors are a group of five muscles located in the medial compartment of the thigh.These muscles are the adductor longus, adductor brevis, adductor magnus, gracilis, and pectineus.. Due to their position, the hip adductors shape the surface anatomy of the medial thigh. For example, the biceps brachii muscle performs flexion at the elbow. These children often have hypertonia of the adductor muscles, making abduction difficult, obstructing normal hip development, and putting them at risk of hip luxation. L2, L3, L4.
