ABSTRACT
In our regions malaria is endemic and intraguteal injection is a common procedure. One unfortunate complication of that procedure appeared to be a sciatic nerve injury. The purpose of our study was to set up the anatomical feature and basis of this post injection lesion. We performed sciatic nerve gluteal dissection on 10 adults black African fresh cadavers on both side. The pathway of the nerve was 19 times in the subpiriformis canal. Only in one cadaver, the outlet of the nerve was above the piriformis muscle. In each case the pathway is identical with an oblique and vertical portion running down through the ischio-trochanteric channel. The nerve was crossed between its two portions by an arteriole coming from the inferior gluteal artery. The cutaneous projection of the sciatic nerve is distant from the upper lateral quadrant of the buttock. Intra-gluteal injections in this area doesn't damage the nerve. The anatomical variations of this nerve pathway are almost nonexistent. So, other hypothesis of sciatic nerve post injection lesion should be considered. We think that the local toxicity of quinine and its diffusion in the neurovascular gluteal area might explain the nerve lesion. Thus, the intramuscular injections should be replaced by the intravenous or rectal administration in children.
