  1. DISCUSSION On close examination, the fingers are disproportionately short for the size of the palm, and the proximal interphalangeal joints are missing except in the small finger. “Syn-” and “sym-” are prefixes with the same meaning: “together”. Take, for example: symphony, sympathy, synchronous, syndactyly, etc., etc.. Symphalangism means a fusion of the phalanges with the absence of pip joints. These fingers are also short, so this is brachysymphalangism. There is no webbing of the fingers here, but simple syndactyly, brachysymphalangism and incompletely formed pectoral muscle and chest wall is known as Poland syndrome.
