slip disk : suraksha kavach ka digna manav sharir idgavar ki jatil karigri ka ek anokha namuna hai. yah anginat choti-choti kodgiakaon se bana hai. yah kodgiakaen sharir men rakt, tvacha, manspedgiayon, haddiyon tatha anya angon ka nirman karti hain. asthi tantra sharir ka vidgosh ang hai, jiski pratyek haddi ki, uske karya ke anurup, ek vidgiasht akriti hoti hai. ek manushya ke sharir men 206 vibhinn haddiyan hoti hain. sharir ka puri tarah se parikshan karne par malum hota hai ki manav sharir men drirh aur kathor haddiyan hoti hain.
agar sharir men haddiyan n hotin, to sharir ka koi akar bhi n hota. sharir ke piche ke bhag men rirh ki haddi hoti hai, jo lagabhag 33 choti-choti haddiyon se mil kar bani hoti hai. har ek-do haddiyon ke bich kartilej, arthat mans ki tah gaddi ki tarah sthit hoti hai. yah lachili tah rirh men lachilapan banae rakhti hai, apas men takrati nahin hai; arthat apsi ragar se bachi rahti hain. girne par, jhatka lagne par, chalne-firne, kudne par yahi gadidyan, ya disk sharir ko suraksha pradan karti hain. rirh ki haddi ke bich se hi vibhinn tantra nalikaen gujrti hain.
atah kartilej unhe bhi surakshit rakh kar mastishk par, ya sharir ke angon par koi hanikarak prabhav nahin parne deti hai. reshon se bana kartilej ka bahri bhag kuch sakhat hota hai, jabki iska bhitri bhag jeli ki tarah mulayam hota hai. achanak jhatka lagne, chot lagne, ya bhari vajan adi uthane par rirh ki haddi ke nichle bhag par vidgosh jor parta hai, jisse kartilej ka enulas faibroras fat jata hai aur jeli vala bhag ful kar bahar a jata hai. ise 'slip diska' kahte hain. disk ke fulne ke sath-sath hi vahan se gujrne vali tantra nalikaen, jo sharir ke nichle bhag aur pairon tak mastishk ke sanket pahunchati hain, prabhavit ho jati hain. unmen dard hone lagta hai. yahi dard saitika kahlata hai.
atah yah spasht hai ki kartilej par dabav, ya jor parne se 'slip diska' aur saitika ka dard ho jata hai. slip disk hone par pith ke nichle bhag par tej dard mahsus hota hai. yah prayah ek or ke sire par hota hai. kabhi-kabhi yah dard ek taraf ke pure pair par fail jata hai. kabhi yah ghutnon ke niche aur kabhi samne ki taraf jangh men bhi hone lagta hai. dard ki shuruat kahan se hogi, yah kaunsi slip disk hai, is par nirbhar hai. slip disk (saitika) hone ke karnah slip disk ki samasya stri, ya purush donon men ho sakti hai. adhik ayu men garbh dharan karne par, bachche ke bhar ke karan, ekaek vajan uthane par, ya motapa iska karan hote hain. kudarat ne har jor ko mashin ki tarah banaya hai aur is mashin par ek nidgichat vajan hi parna chahie. vajan barhne se kamar ki haddiyon ke bich ki disk dhire-dhire ghis kar kamjor ho jati hai
aur niche jhuk kar uthne, jhuk kar kam karne par 'saitika' slip disk ho jata hai. slip disk agar nari par dabav dalti hai, to usi ko saitika kahte hain. ajakal prayah log vyayam nahin karte, jis karan, umra ke sath-sath, sari chijon evan joron men vighatan hone lagta hai. aise vyakti, jo lagatar sarko par skutar, saikil, ya motar se chalte hain, sarkon ke gaddhe, spid brekar par jhatkon ko jhelte hain, unko sara dabav kamar ke nichle bhag par sahan karna parta hai, jisse slip disk ho sakta hai. upchar : dard mahsus karne par kuch dinon ke lie jamin par, ya takhat par karavat le kar, donon pair mor kar letna chahie. sidhe chitt n leten. aisa karne par disk apne ap andar chala jata hai aur aram mil jata hai. saitika dard yadi ek, ya do saptah se ho raha hai aur davaiyon ke sevan se bhi thik n ho, to daktar ki salah leni chahie. kabhi-kabhi daktar tairakshan lene ki salah bhi dete hain.
isse manspedgiayon ko ahsas bana rahta hai ki kamar men taklif hai, taki vah age jhuk kar kam n kar sake. yadi kisi bhi tarah se aram n ho, to aupredgan dvara nariyon par parne vale dabav, ya bhar ko hata kar ilaj kiya jata hai. aupredgan dvara prabhavit sthan ke disk ko hata kar, ya use thik kar ke 'ki hol sarjari' ki jati hai. savdhaniyan : jamin par giri vastu ko uthane ke lie ekaek n jhuken; balki ghutne mor kar jamin par baith jaen aur vastu utha kar fir khare ho jana chahie. dayen-bayen achanak kalai mor kar vastu uthane ki apeksha svayan ghum kar vastu uthaen. donon hathon men saman bhar uthana chahie, n ki ek men adhik bhar aur dusre men kam. pith ki manspedgiayan ekadam sidhi rakhni chahien. pith ko ekadam sidha rakh kar niyamit rup se vyayam karna chahie.
