The study of the union of normal fascia with muscle has been the subject of a number of investigations. Because of the close relationship of this problem to the one to be presented it seems advisable to review some of these papers briefly. In a report based on experimental and clinical observations, Seelig and Chouke1 stated that muscle would not unite with fascia. They performed a series of experiments on animals, in which they reduplicated the fascia lata to simulate Poupart's ligament, and sutured the edge of the turned flap to the underlying muscle. In every experiment they found that the fascia lata was separated from the muscle by loose areolar tissue and failed to unite firmly. Koontz2 repeated the experiment of Seelig and Chouke, but removed the loose areolar tissue from the fascia lata; he obtained firm union in every case. He claimed that the failure of
