    CHAPTER VI POST-OPERATIVE TREATMENT OF SPECIAL COMPLICATIONS Nerve Symptoms after Lorenz's Operation.—When it is realized that this operation actually lengthens the affected limb sometimes by as much as 3 inches or even more, it is not to be wondered at that nerve-symptoms have been observed to follow the operation. The commonest of these is paralysis of the external popliteal (or peroneal) nerve. The relative fixity of this nerve as it passes round the neck of the fibula probably accounts for the external popliteal nerve resenting elongation more than the internal does. A more alarming paralysis is one affecting the nerves of the whole lower limb. This can only take place in cases where operation has been delayed beyond the years of safety. The cause of the paralysis must, I think, be attributed to increased tension on the spinal nerve-roots. Examina- tion of a lower limb that has been avulsed by accident shows that the roots of the sacral nerves, including the posterior spinal ganglia, remain in continuity with the great sciatic nerve. Whenever the degree of shortening and the length of the femoral neck point to an unusual strain on the parts around the hip-joint after reduction, a careful preparatory course, including daily manipulations,
