Often, the instability disappears with age, with the build-up tugopodvizhnosti spinal column. Spondilolistez Degenerativnye spondilolistezy most frequently occur at the level LIV-LV because of the weaker svyazochnym apparatus broad disk interval, the joint surfaces. An degenerative spondilolisteza help : 1) constitutional options and the surfaces fasetochnyh joints; 2) the mechanical strength subhondralnoy bone (mikroperelomy against osteoporosis resulted in a change in the joint surfaces); 3) Reducing the load resistance of the intervertebral disc exposed degenerativnomu process; 4) increased lumbar lordosis through changes svyazochnogo apparatus; 5) weakness of the muscles in the body; 6) obesity. The appearance of neurological symptoms in this state due to the narrowing of the central and deformation and koreshkovogo channels intervertebral holes. Perhaps the development of symptomatic neyrogennoy leg, compression roots LIV and LV spinal nerves in listeze at LIV-LV. Degenerativny spondilolistez be reconciled with the manifestations segmentarnoy spine instability. Conservative treatment provides a set of common activities associated with treatment of pain in his back.
