The international encyclopaedia of surgery; a systematic treatise on the theory and practice of surgery . s are formed, theloosening of which affords abundantroom for the future steps of the opera-tion, while it entails no transverse divi-sion of muscular fibres.

The head and neck of the bonebeing free, the femur is to be rotated first in one direction and then in theother, while the muscles attached to the trochanters are shaved off close totheir insertions, and the limb is then forcibly adducted and pushed upwards,so as to make its upper extremity i)roject through the wound, when it is cutthrough with the chain-saw just below the great trochanter.
