Pulled-in-Two Syndrome
Dehiscence of a muscle during surgery has been termed pulled-in-two syndrome (PITS). The dehiscence usually occurs at the tendon–muscle junction, and the inferior rectus may be the most frequently affected muscle. Advanced age, various myopathies, previous surgery, trauma, or infiltrative disease may predispose a muscle to PITS by weakening its structural integrity. Treatment is recovery, when possible, using techniques similar to those used for lost muscles, and re-anastomosis of the muscle.
