Spondylolysis & Spondylolisthesis

Low back, pelvis & core · Before your visit

Spondylolysis is a stress injury in part of a vertebra, while spondylolisthesis is forward slippage of one vertebra.

When to seek urgent medical care

Get urgent medical help for new loss of bladder or bowel control, numbness around the groin or saddle area, rapidly worsening leg weakness, fever with severe back pain, or pain after major trauma.

This is not an exhaustive emergency list. If something feels severe, rapidly worsening, or unsafe, call 911 or seek urgent medical evaluation.

What is spondylolysis & spondylolisthesis?

Spondylolysis is a stress injury in part of a vertebra, while spondylolisthesis is forward slippage of one vertebra. These findings are especially relevant in young athletes with extension-related back pain and require load management and medical coordination.

The same label can behave differently from one person to the next. The timing, location, type of symptoms, injury mechanism, and response to movement help distinguish a local tissue problem from referred pain, nerve involvement, or a pattern that should be evaluated elsewhere first.

What spondylolysis & spondylolisthesis can feel like

People do not need every sign below to fit this pattern. They are useful clues to discuss during an evaluation, especially when paired with what changes the symptom and what activity has become difficult.

  • back pain with extension
  • pain during gymnastics, football, or throwing
  • hamstring tightness
  • symptoms that rise with running or jumping

Common contributors and aggravators

A contributor is not always a single cause. Tissue capacity, recovery, the size of a recent load change, and the mechanics of the task can overlap. For spondylolysis & spondylolisthesis, the history commonly examines:

  1. 1repetitive spinal extension and rotation
  2. 2growth and high training volume
  3. 3bony stress injury

What we look at before planning care

An assessment begins with the story, then tests the findings that can change a decision. For this presentation, that usually means looking at the items below and comparing them with the demands of work, daily life, or sport.

Clinical focussport and growth history
Clinical focusextension response
Clinical focusimaging and medical guidance when stress injury is suspected

Imaging can be useful when the history or examination indicates it, but a scan is not a substitute for matching the finding to symptoms, function, and the clinical screen.

This page explains what we look at and what care can involve. It is not a diagnosis, and it cannot replace an examination. Bring the problem in and a provider will tell you what is going on.

What your provider will discuss with you

Care for spondylolysis & spondylolisthesis is built around the findings, not a preset protocol. The early goal may be symptom control or protection; the later goal is enough motion, strength, and tolerance for the exact activity you need.

01

remove painful impact and extension early

Progress is checked against symptom response and function so the plan can change when capacity changes.

02

restore trunk and hip capacity

Progress is checked against symptom response and function so the plan can change when capacity changes.

03

use criteria-based return to sport

Progress is checked against symptom response and function so the plan can change when capacity changes.

Common questions about spondylolysis & spondylolisthesis

Short answers to the decisions people usually face before an evaluation.

What is spondylolysis & spondylolisthesis?

Spondylolysis is a stress injury in part of a vertebra, while spondylolisthesis is forward slippage of one vertebra. These findings are especially relevant in young athletes with extension-related back pain and require load management and medical coordination.

How is spondylolysis & spondylolisthesis assessed?

The examination is shaped by your history and the task that brings symptoms on. For this pattern, useful checkpoints include sport and growth history, extension response, imaging and medical guidance when stress injury is suspected. The provider also screens for findings that should be evaluated medically before musculoskeletal care continues.

What can care for spondylolysis & spondylolisthesis include?

A plan may draw from Physical Therapy, Chiropractic, and KT Taping, but the service is not the diagnosis. Care is selected around the examination and may focus on remove painful impact and extension early, restore trunk and hip capacity, use criteria-based return to sport. The dose and sequence change with irritability, healing stage, and the activity you need to regain.

Can I stay active with spondylolysis & spondylolisthesis?

Often, some activity can continue after the provoking dose is adjusted, but that decision depends on the tissue, severity, and warning signs. The goal is to protect what needs healing while preserving safe strength and conditioning, then rebuild the specific work, daily-life, or sport demand.

When does spondylolysis & spondylolisthesis need urgent medical care?

Get urgent medical help for new loss of bladder or bowel control, numbness around the groin or saddle area, rapidly worsening leg weakness, fever with severe back pain, or pain after major trauma.
