Abstract

performed extensive stretching of the hamstring muscles resulting in the inability to extend her knee. Furthermore she showed symptoms of perineal nerve palsy of the same leg. In the diagnostic course it was found that the sciatic nerve was compressed by a Heterotopic Ossification (HO) of the greater trochanter. The stretching lead to a dislocation of the nerve around the HO, which prevented the nerve to slip back in its anatomical position. Operation was performed and the neurological symptoms diminished.
