BACKGROUND/ PURPOSE: Thoracoscopic Nuss repair of funnel chests is used increasingly, but has a high bar dislocation rate. The authors intended to reduce this by technical modifications of the original Nuss technique. METHODS: In 40 patients from 12.3 to 42.1 years of age (mean, 17.6 +/- 5.8) the bars were placed directly on the ribs in a submuscular position and fixed by a minimum of 14 absorbable figure of 8 sutures around the bar and the underlying rib placed under bilateral thoracoscopy. Two stabilizers were used in all patients, the bar was introduced from the left in severe cases, and a second bar was implanted in most beyond 16 years of age. All patients underwent follow-up to date in a prospective observation study. RESULTS: There was no bar or stabilizer dislocation, no prolonged pain or neuralgia, but one traumatic seroma, one pleural, and one pericardial effusion. One bar was easily removed after 13 months. CONCLUSIONS: Submuscular position provides a far better bar fixation and soft tissue coverage of Nuss implants. The technique is technically more demanding but safe and has reduced the incidence of bar dislocation to zero in this early experience of 40 adolescent patients, although no sportive restrictions were imposed on the patients at all.
