Pelvic Tilt / Functional Leg Length Discrepancy

Pelvic Tilt / Functional Leg Length Discrepancy

Do I have a Pelvic Tilt Condition?

There are three types of pelvic tilt. The most common is the anterior pelvic tilt. The front of the pelvis rotates forward, making your pot-belly if you have one, even more noticeable. The shift in body weight forward causes poor posture, low back pain and aching back muscles.

The second type is posterior pelvic tilt and occurs when the back of the pelvis is tilted downward. The back appears to sway backward.

The third type is lateral pelvic tilt, which occurs when one side of the pelvis is higher than the other, and may be seen in patients suffering from scoliosis or a muscle imbalance. Any of the pelvic tilts will cause hip, knee, posture and gait problems.

How Common Is Pelvic Tilt/Functional Leg Length Discrepancy?

According to studies, between 90% and 95% of Americans have a leg that is shorter than the other by more than a quarter of an inch. The rate of occurrence is so high, the condition of functional leg length discrepancy (FLLD) was in the past considered normal and not worth attention. In fact, the condition can be quite serious in its long-term impact on the hips, knees, ankles and feet.

It is not uncommon for a patient’s longer leg to be prone to degenerative joint disease, osteoarthritis, and have higher rates for stress fractures. The body naturally compensates for the asymmetry, which puts more pressure on the dominant leg to compensate for the shorter one. Foot, ankle and knee problems can occur in both legs and may worsen with age if not corrected.

How Much of a Leg Discrepancy Merits Attention and Correction?

Many orthopedists feel that any leg shortness greater than 1/8 of an inch deserves attention and treatment to bring the body into balance. Functional Leg Length Discrepancy also causes pelvic tilt problems that can severely affect posture and cause sciatica and low back pain.

What are the signs and symptoms of Pelvic Tilt and Functional Leg Length Discrepancy?

  • Shortness of one leg
  • Posture problems, slumping forward or backward, tilting shoulders
  • Walking problems, limping, toe walking
  • Hyperextended knee on the short side
  • Flexed knee on the long side
  • Pelvic tilting to the front, rear or side
  • Pain in the lower back, hips, knees, ankles and feet

Can Pelvic Tilt/Functional Leg Length Discrepancy be treated using a Regenerative Strategy, or should I just give up and have an operation?

Yes, it can. Dr. Greenberg’s regenerative treatment is an excellent alternative to an operation which should always be the last option. He has been treating Functional Leg Length Discrepancy for over 20-years with great results. The procedure is important because of the many musculoskeletal conditions that are affected by postural imbalance and pelvic tilt.

Dr. Greenberg will perform a Comprehensive Kinetic Diagnosis, including a review of your most recent radiographs. We will assess your gait, measure your legs or check for pelvic tilt to see if your musculoskeletal systems are balanced.

If you are an appropriate candidate for Kinetic Regeneration Therapy, Dr. Greenberg will treat your Pelvic Tilt or Leg Discrepancy by recommending the healing and synergistic cascade of Prolotherapy, Platelet Rich Plasma (PRP) and Stem Cell Treatments. The combination of proliferative cells, healing factors and your stem cells interact to stabilize pelvic tilt and functional leg length discrepancy. The condition usually requires two treatments to correct the discrepancy. If we find additional areas that may be causing pain, we will try to fix those too. Our team treats the whole YOU, that’s what holistic care means to us. We work to renew you physically and emotionally.

If you or a loved one is looking for a new strategy to treat chronic aches and pains, fill out the form on this page to schedule an appointment or call Dr. Greenberg’s office today at (833) 440-4325.

In order to mitigate the spread of COVID-19 in our community, any patient that enters the building will be screened for the virus by having their temperature taken and filling out a questionnaire from Main Line Health. Once inside the office, patients will be asked to wash their hands immediately and may receive another temperature check. All patients will be able to maintain a safe social distance from others, as only one patient is seen per hour. The Greenberg Regenerative staff wears their masks at all times, and also ensures that all safety protocols and guidelines per Main Line Health and the CDC are being followed. Additionally, Dr. Greenberg is fully vaccinated, which further reduces possible COVID-19 transmission. At the end of the appointment, patients have the option to take a Greenberg Regenerative Medicine hand sanitizer to allow them to remain safe and healthy.
