The tabularx package is good to fit a tabular to a specified width. Here it’s the current \linewidth (→ Difference between \textwidth, \linewidth and \hsize).
I guessed that the two most left columns should be twice as wide as the other ones. According to this I have set \hsize. (The sum of all \hsize still have to be the number of X columns.)
I have also reduced the horizontal space between columns:
\setlength{\tabcolsep}{.3\tabcolsep}
With the \cline{2-10} you can specify a \hline that only goes from the second to the tenth column.
Code
\documentclass[twocolumn]{article}
\usepackage{tabularx}
\newcolumntype{F}{>{\bfseries}c}
\begin{document}
\begin{table}[t]
\centering\setlength{\tabcolsep}{.3\tabcolsep}
\begin{tabularx}{\linewidth}{|*2{>{\centering\hsize=1.6666\hsize}X|}*8{>{\centering\arraybackslash\hsize=.83333\hsize}X|}}
\hline
\multicolumn{2}{|c|}{} & \multicolumn{8}{F|}{Wrist} \\
\multicolumn{2}{|c|}{} & \multicolumn{2}{F}{1} & \multicolumn{2}{F}{2} & \multicolumn{2}{F}{3} & \multicolumn{2}{F|}{4} \\ \hline

I have used \resizebox from graphicx package ti re-size the table to fit inside the column. Also, I have replaced all +- in to \pm.

hworks in two column just as one columnwill make the float appear "here" i.e. mid column if it fits at that point.
