-early vertebral slippage kita panggil 'SPONDYLOLYSIS'
...Bila berlaku kejadian vertebral slip forward 2..nerve root pun kena hentam la..apa lg.so..pesakit mula merasai kesakitan like..numbness,tingling,weakness,muscle spasm,thigh,sharpness pain...Doktor called ni 'SCIATICA'
...When the vertebral 2 slippage..there is a defect in the 'pars interaticularis'..dia bergerak secara unilateral r bilateral (x faham..x pa)biasanye kat L5 (5th lumbar vertebra)..some cases,kanak2 lahir without face joints (dysplastic joints) n ada juga cause of infection r tumor..so..bergeraklah tulang tu sebab x stabil..like a doctor...kwang..kwang..
