Abstract
Trunk muscles are an important source for pedicled and free flaps in reconstructive surgery. Unilateral deficiencies of trunk muscles are well known, either isolated or as part of Poland’s syndrome. Bilateral muscular deficiencies and a “bilateral Poland anomaly” have also been sporadically reported, but this is rare. We report on an 82-year-old male cadaver with clinically obscure, asymmetric bilateral deficiencies of the majority of trunk muscles. There was a history of acute poliomyelitis in childhood. Histological examination of representative muscle samples of the trunk showed extensive muscle atrophy with fat and connective tissue replacement. This was compatible with the prior diagnosis of poliomyelitis. However, representative sections of the spinal cord failed to reveal the antecedent poliomyelitis. The possibility of subclinical bilateral deficiencies of trunk muscles has to be taken into account in patients with ahistory of poliomyelitis when planning reconstructions in cases of regional pedicled muscle transfers or free microvascular tissue transfers in reconstructive surgery.
