Pucketavi zglobovi – misterij suvremene znanosti

Pucketanje zglobova na rukama za mnoge je iritantna ili neugodna pojava. No, iako ju uzimamo zdravo za gotovo, ona još uvijek predstavlja svojevrstan misterij za znanstvenike.

Tako je primjerice Caroline Werkmeister, ortoped u hamburške sveučilišne bolnice, otvoreno izjavila da znanost još nema blage veze zašto i kako točno dolazi do ove pojave.

Ipak, imaju neke teorije. Tako po novom pretpostavljaju da ova tjelesna pojava, koja je u nekih ljudi jače a u drugih slabije izražena, ima neke veze s nakupina ugljikova dioksida i dušika u predjelu između zglobova prstiju na ruci. Njihovo nakupljanje uzrokuje snižavanje tlaka zraka među zglobovima, što bi moglo izazvati pucketanje.

Pretpostavlja se da zvuk pucketanja nastaje kad plin u našim zglobovima naglo prijeđe u tekuće stanje, što je odgovor tijela na smanjenje tlaka u zglobovima. No, ovu radnu teoriju tek treba dokazati konkretnim istraživanjima.

Iako ne znamo što uzrokuje pucketanje prstiju, treba znati da je ova pojava u pravilu potpuno neškodljiva. Nekad se pričalo da se čestim pucketanjem prstiju “troše” kosti zglobova, ali prema današnjim saznanjima to nije istina. Liječniku biste se trebali obratiti jedino ako vam pucketanje zglobova uzrokuje bol, što nije česta pojava.

Eto ti što je ljudska znanost. Hvalisamo se kako ćemo uskoro na Mars. Ma, zapravo, kakav Mars – uskoro će tajne svemira biti naše! A pritom nam nerazrješiv misterij i dalje predstavljaju naše vlastite ručice.
