Method comparison--a different approach.

The commonly accepted method of analysing data from method comparison studies is regression analysis, a method which has limitations. This study illustrates the use of a graphical presentation of data, the difference plot, which can be used as an alternative to least squares regression analysis. The data from comparison studies performed on five methods were analysed both by Deming's regression analysis, with calculation of the correlation coefficient, and by the difference plot. The results show that in most cases much more relevant information was obtained from the difference plot.

Local neurovascular island flap.

Fingertip amputation, with loss of the terminal pulp and bone exposure presents a difficult problem. Reconstruction with use of a local neurovascular island flap has been done in twenty-one patients to restore sensibility and function with preservation of length. All patients achieved two-point discrimination values within two millimeters of the normal contralateral fingertip, with adequate pad for pain-free pinch. We advocate this procedure for deep pulp loss over the distal phalanx. It is reliable, single-staged, and provides skin coverage closer to normal than any regional flap technique.
