OBJECTIVES: O. Sacks describes in his book "A leg to stand on" the inability to move his leg for along period after rupture of the tendon of m. quadriceps. He refers the history of similar cases, especially of a woman with a hip fracture. He discusses this as a result of disruption of proprioception (peripheral induced neglect). The aim of this investigation is to answer the question how frequently this symptom may be found in patients with hip fracture and/or arthrosis perioperativly after implantation of a total prosthesis.
METHODS: we examined 106 patients aged 70.35 +/- 10.01 years (36-male 67.54 +/- 9.74 years and 69 female 71.9 +/- 9.9 years) who underwent an implantation of a hip prosthesis - antero-lateral access Watson-Jones - (right side n = 61, left n = 44) because of arthrosis (n = 81) or a hip fracture (n = 18) on postoperative day 1./2. and 10. - 14. Besides exact neurologic examination, we particularly asked for changed perception of the operated leg.
RESULTS: by neurological examination we found only rarely signs of peripheral nerve lesion as a complication of implantation of hip prosthesis (1 femoral nerve lesion, 1 ischiadicus nerve lesion). 14 patients reported a changed perception at the first examination: 5 patients felt their operated leg shorter or longer, 4 patients described their leg changed in a strange manner (like a block of wood or lead), 2 patients felt their leg changed, but could not tell how. At follow-up examination there was no patient with a changed perception of the operated leg.
CONCLUSIONS: at first examination only a small number of patients report a changed perception of the operated leg. Early mobilization of the operated leg may be the cause of quick normalization of perception. The peripherally induced neglect, described by O. Sacks, was possibly caused by decrease of cortical representation because of immobilization, but not by disrupted proprioception.
