E ai ki a Virchow wehewehe rua ngā momo o te pukupuku: geteroplasticheskie (i hanga i te kiko tūhonohono), hyperplastic (i hanga i te wheua). Ko te rōpū tuatahi ngā osteophytes - papa iti i te wheua. Ki te noho ratou i te paenga katoa o te wheua, kua karangatia e ratou hyperostosis. Ki te tukuna wheua papatipu i roto i te puka o te pukupuku i roto i te whāiti o te wāhi, exostosis reira, ki te te roto i te reira i roto i te wheua - enostosis.

Haumanu tohu osteoma
