CPT® Code 27100

The procedure described by CPT® Code 27100 involves the transfer of the external oblique muscle to the greater trochanter, which is a bony prominence on the femur. This surgical intervention is primarily indicated for patients suffering from abductor paralysis, a condition that impairs the ability to abduct the hip. The transfer aims to enhance hip abduction by repositioning the muscle, thereby improving functional mobility. The procedure begins with a long oblique skin incision that extends from the pubic spine, traversing over the iliac crest and reaching up to the costal margin along the posterior axillary line. This incision allows access to the external oblique muscle, which is then carefully manipulated to achieve the desired transfer. The surgical technique involves incising the aponeurosis of the external oblique muscle and creating additional incisions to free the muscle fibers, ultimately facilitating their attachment to the greater trochanter. The meticulous dissection and suturing techniques employed during this procedure are crucial for ensuring proper healing and functionality post-surgery.
