[A new technique of posterolateral thoracotomy with preservation of the latissimus dorsi muscle].

The authors present a new posterolateral thoracotomy technique, preserving the integrity of the latissimus dorsi muscle, which in split in the direction of its fibres instead of being sectioned transversely. The exposure is sufficient for all forms of lung resection and pleural surgery and the incision is easily and rapidly repaired. After describing the technique, the authors review their first 70 patients operated via this incision, which was always sufficient to allow the planned operation. Healing was satisfactory and, in the long-term, the functional and painful sequelae appeared to be less than with the classical Crafoord posterolateral thoracotomy, which could be replaced by this new incision.
