That is correct.
Anterior spondylolisthesis is a condition where a vertebra in the spine slips forward over the one below it. This can result in compression of spinal nerves, leading to symptoms like back pain, leg pain, and weakness. Treatment often involves physical therapy, medication, and in severe cases, surgery may be necessary.
If you fly over the International Date Line, the Pacific Ocean is typically below you. The International Date Line roughly follows the 180° line of longitude, so if you fly directly over it, you will likely be over the Pacific Ocean.

spondylolisthesis
Spondylolisthesis is the forward displacement of one vertebra over the one beneath it. It commonly occurs in the lower lumbar region, especially between the fifth lumbar vertebra and the first sacral vertebra (L5-S1).
Spondylolisthesis is the degenerative condition of the spine where one vertebra slips or moves anteriorly over another vertebra. This can lead to symptoms such as lower back pain, leg pain, and muscle stiffness. Treatment options may include physical therapy, medication, and in severe cases, surgery.

Spondylolisthesis generally refers to an anterior displacement of one vertebra from its normal position on top of another. There are a few different ways to grade them.According to the most common method:Grade 1 - 1-25% displacementGrade 2 - 26-50% displacementGrade 3 - 51-75% displacementGrade 4 - 75-100% displacementGrade 5 - >100% displacement (also called a spondyloloptosis, the vertebra has slipped entirely off of the one below it.)Most of the time these happen so gradually that a person may be asymptomatic, or have far less symptomatology than you might expect based on a look x-ray or MRI images, as the body has time to adapt. Nevertheless, rehabilitating the pelvic and abdominal muscles to ensure optimal posture and chiropractic maintenance care would be a good plan.
This condition is know as spondylolisthesis. There reasons for this can be broadly categorized as congenital, devlopmental, degererative , traumatic and neoplastic.This is a common condition seen after spondylolyis which is a defect in posterior part of the vertebra that displaces forward.Old age may also lead to similar problems due to degeneration (wear and tear ) of the facet joints.People with this problem generally do not have any problems - most of them will have pain on extension of the spine.if associated with stenosis due to anterior slippage they may develop symptoms due to lumbar canal stenosis.Spondylolisthesis is the slipping of one vertebra from its proper place over the one below it.spondylolisthesis
A posterior subluxation of L5 on S1 means that the lowest lumbar vertebra has translate posterior and is likely inferior relative to the spinous. In other words the lowest bone before your sacrum is has slipped backwards and the little bump, such as those you feel when you run your fingers over someone's vertebrae, is pointing slightly downward. A subluxation invloves a very, very small amount of displacement. Sometimes as little as a fraction of a millimeter.
Spondylolysis is a condition characterized by a stress fracture or defect in the pars interarticularis of a vertebra, often occurring in the lower back. Grade 1 spondylolisthesis refers to a mild forward slippage of one vertebra over another, typically assessed on a scale of 1 to 4, with grade 1 indicating less than 25% displacement. Together, these conditions can lead to lower back pain and may affect spinal stability. Treatment may involve physical therapy, pain management, or in some cases, surgery.
Spondylolisthesis surgery is typically performed to correct the displacement of one vertebra over another in the spine. This condition can lead to compression of spinal nerves, causing pain, weakness, and numbness in the legs. The surgery aims to stabilize the affected vertebrae, relieve pressure on the nerves, and restore alignment to improve overall spinal function and alleviate symptoms.
Our spinal cord protects the nerves that send messages to the brain. It is made up of a series of connected bones or vertebrae. Commonly occurring in the lower back, Spondylolisthesis develops when a vertebra slides over the bone beneath it. Infection, overuse of the affected joint, lack of exercise, and aging are a few reasons why Spondylolisthesis occurs. The degree of slippage determines how severe the symptoms are. There are different ways in which spinal fixation is approached. Some approach it from the back of the spine, known as Posterior Lumbar Interbody Fusion while some approach it from the side known as Transforaminal Lumbar Interbody Fusion. Both methods can be used depending on the patients’ medical history. Ranka Hospital, Pune provides treatment and facilities for spine problems.
This is a phenomena whereby bone remodeling takes place due to gravitational stresses as well as asymmetrical forces upon bones. It is most commonly noted in the spine. A vertebra under asymmetrical forces due to osseous disrelationships with the vertebra above or below. Over time an adaptation takes place causing the vertebra to become wedged from left to right in the body's innate attempt to equallibrate forces acting upon the spine. This may be the source of scoiliosis in some cases. This type of scoliosis is a normal variant, not a pathological occurence.
In younger adults (20-60 year olds) the most common causes of back pain are nerve impingement and problems with the discs, for example lumbar disc herniation or degenerative disc disease. In older adults (over 60 years old), the source of back pain or leg pain is more likely to be the facet joints or osteoarthritis, and back conditions may include facet joint osteoarthritis or degenerative spondylolisthesis (occurs when the disc and facets wear out and the vertebra above slips forward on the one below.
