How Long Does it Take for Pars Defect to Heal?

Wednesday, May 15, 2019

We all know that feeling of an aching lower back. How can you know if that pain is a simple soreness or the result of a stress fracture, or maybe even a pars defect?

Pars defect, otherwise known as spondylolysis is a fracture within the pars interarticularis of the vertebral arch in the spinal column. To put it simply, the defect is a stress fracture of the bones of the lower spine that results in lower back pain. Rather than being in the center of the back, this back pain is usually on one side of the back. When a pars defect does not heal it can lead to spondylolysis which is a permanent pars fracture on both sides of the spine.

When this occurs, the spine can slip backwards over time which would result in a more serious condition of what is commonly referred to as spondylolisthesis. This, then increases the possibility of a degenerative vertebra and further back conditions in adulthood. The good news that these back problems can be prevented with early diagnosis and treatment methods.

It may not sound too serious but like other fractures, a stress fracture is a break in the bone. It’s only referred to a “stress” fracture because it develops as a result of repetitive stress and overuse that is usually associated with sports and activity. This differs from a specific acute event or injury which may create pain suddenly and quickly from a specific event or injury.

How do you know if you or your child suffer from a pars defect?

The pars defect is one of the most common causes of lower back pain in younger athletes. The lifetime prevalence of lower back pain with a pars defect in those aged 11-17 years has been reported to be as high as 30.4% among adolescents participating in sports. The condition is more common in males; 2-1

The structure of a pars bone is small, and it grows longer during adolescent growth. Therefore, it is very thin and weak, and very much prone to injury during young adolescence. Kids and teens who play sports and do activities that can strain the lower back or that involve a lot of lower-back stretching — like football, weightlifting, wrestling, cricket – bowling action, gymnastics, volleyball, ballet, and golf — are especially likely to have these problems.

Placing extra strain on this area of the spine during childhood increases the chance that a pars defect will occur.

Symptoms of a pars defect usually have one of the following;

  • pain in the lower centre back that might feel like a muscle strain
  • pain in the thighs and buttocks
  • stiff muscles and tenderness in the lower back region
  • muscle tightness, especially in the hamstring muscles
  • Pain radiating down one or both legs
  • Numbness, tingling, and weakness in legs

Diagnosis Of Pars Stress Fracture

Since a pars fracture is a break in the bone, only rest and time will promote healing. Most people with a pars defect do not require surgery with anti-inflammatory medications, physiotherapy and recovery the recommended means of dealing with a pars stress fracture.

Typically, the average recovery rate of Pars Fracture can be anything from between 6-12 weeks.

Recovery is the most important aspect for the initial stages of a pars stress fracture. With the guidance and implementation of  Physiotherapy, individuals with a stress fracture should expect a series of strengthening exercises for the abdominal and low back muscles to combat the pain and rehabilitation from their physiotherapist.

In some cases, a complete recovery from a pars stress fracture can take as long as 6 months.

When symptoms and pain are not relieved with nonsurgical treatments patients may require surgery. Surgical options for a pars defect include a pars repair versus a lumbar fusion.

Injections are another alternative but more commonly used for in the adult population. Injections might help control the pain enough to least keep you functional. In some cases, injections will have very little affect for some adults and if they do work, the injections do have the tendency to wear off. However, the positive implications of using injections is that they are a very low risk and less invasive technique to adopt.

How can you prevent the possibility of this fracture and pain in your spine?

There are actually a few things that you can do to avoid getting a pars stress fracture including;

  • Taking a break from sports every few days
  • Maintaining good physical condition during the off season
  • Increasing high impact activities gradually
  • Increasing hours in sports gradually
  • Avoiding year-round participation in sports
  • Maintaining flexibility in the hamstrings and hip flexors
  • Increasing strength in the lumbar and core muscles.
