Do you know why the lower back levels which are medically termed as L4-5 and L5-s1 are most commonly affected? Get to know about it from Best spine surgeon in Mumbai- Dr Sameer Ruparel at Spine Solutions Clinic
But before we understand why it happens, it is necessary to know something basic about lower back spine. The lower back consists of 5 spinal bones known as Lumbar vertebrae labelled from L1 to L5 and then starts the sacral vertebrae from S1 onwards. Between these bones is the intervertebral disc which acts a shock absorber. The disc between L4 bone and L5 bone is known os L4-5 disc and likewise. Also, behind these bones and disc is the spinal cord which contain spinal nerves suppling power and carrying sensations to and fro from the legs. Thus, if any pathology affecting these structures may cause back pain, leg pain, tingling, numbness or ‘sciatica’ like symptoms. Most common pathology that our spine specialist in Mumbai- Dr Sameer Ruparel commonly sees in young patients is ‘slipped disc’ -where the disc slips from between the bones behind and presses on nerves.
But why are these levels L4-5 and L5-S1 most commonly affected? This is because the whole body load gets concentrated on these levels while standing, sitting and walking. While bending forwards or sitting on floor, this load increases significantly. This makes these levels most prone to degeneration which is common termed as Lumbar ‘Spondylosis’.
Thus, if you are suffering from Spondylosis or slipped disc at L4-5 or L5-S1 visit best spine surgeon in Mumbai – Dr Sameer Ruparel for expert and most advanced treatment options.
