| Total UPDA | 20 | 220 | 87 | |
Values are presented as number (%). More than one UPDA was observed in 32 hands where in addition to UPDA from the FPMA significant UPDA to the thumb came from one of the other superficial palmar arterial system. UPDA, ulnar palmar digital artery; FPMA, first palmar metacarpal artery; UA, ulnar artery; SPA, superficial palmar arch; SPBRA, superficial palmar branch of radial artery; FDMA, first dorsal metacarpal artery; MA, median artery; UDDA, ulnar dorsal digital artery.
