What are the causes of the dimples commonly found above the buttocks? They seem to be in line with the sacroiliac joints. Do the joints have anything to do with them?
Back dimples or Dimples of Venus are created by a short ligament stretching between the posterior superior iliac spine and the skin. They are thought to be genetic.

Sacroiliac Syndrome: Common Cause of Low Back Pain
Low back pain is one of the most costly and disabling of all neuromusculoskeletal conditions, affecting over 80% of the population at some point.
In fact, at any given moment 7% of adults are experiencing a spell of back pain that will last two weeks or longer.
Sacroiliac (SI) syndrome is a specific form of back pain that affects the area in and around the dimples in the upper buttocks. People with this condition usually experience localized pain in the low back, as well as pain in the groin,testicle, hip or back/front of the thigh, but rarely below the knees.
The latter is called referred pain, meaning it travels from the source of the problem to other regions of the body. Those suffering from SI syndrome also commonly experience sharp pain after straightening up from a stooped position, often while lifting an object.
Twisting, leaning forward, bending backward and sitting for long periods of time can make the pain worse.
While SI syndrome can begin without warning, it's often a continuation of a similar, milder condition called SI irritation.
If people don't seek treatment when they have SI irritation, which mostly manifests as localized pain in the mid-buttocks, the condition can develop into SI syndrome.
Abnormal movement in the sacroiliac joint, a joint comprising two bones, the sacrum and the ilium, generates this pain. You have two ilia, and can feel them if you put your hands on your hips, just below your waist.
The bony protrusions on either side are the ilia, which connect to the lower part of the spine, the sacrum. The connections between the bones are the sacroiliac joints.
Medical studies estimate that these joints are responsible for about 10% to 30% of low back problems.
Theories postulate that jamming of the joints, hormonal influences and arthritis are responsible, and research also shows that lifting and bending make patients more susceptible to the condition, particularly children, pregnant women and those with a degenerative disease.
All these factors can lead to local inflammation and joint irritation that then lead to pain. With SI syndrome, the irritation and inflammation also affect nerves that provide sensation to other areas, like the thighs, which causes the brain to perceive pain as coming from the lower limb as well as from around the sacroiliac joints.
These symptoms are chronic and aggravating, so you'll want to see your Dr. Grisanti as soon as possible if you have SI syndrome. Dr. Grisanti can provide effective management for your condition, and can help you improve joint function, decrease pain and get your low back to its original state.
What are back dimples?
According to Lloyds Pharmacy pharmacist, Pareena Patel, back dimples are physical indentations of the joint on your lower back where your pelvis and spine meet. "They are created by the ligament that attaches your superior iliac spine and your skin," she explains.
So - what does the science say? "Research into why they are formed and their purpose is somewhat limited," Pareena notes. "One study which looked at the &lsquoattractiveness&rsquo of the &lsquoDimples of Venus&rsquo in America and Turkey found that men preferred these dimples on women," she explains.
However, the evidence and research kind of runs out there. There's not enough conclusive scientific evidence, yet, to give back dimples any medical meaning, other than that they are indentations over a joint.
N.B. here - back dimples should not be confused with a &lsquosacral dimple&rsquo, which presents as a small dimple at the base of the spine. "When present in young babies, this can in some rare cases if deep, could indicate problems with the lower part of the spinal cord and as such should be approached very differently," Pareena warns.
Everything You Need to Know About Dimples
When you hear the phrase “dimples,” what images pop into your mind? A cute girl with indents in her cheeks when she smiles? The newest trend of back dimples? What about cleft chins?
Whether you’re a fan of dimples or not, you’ve probably wondered what causes dimples or why some people have them and others don’t. Here’s everything you need to know about dimples!
What are dimples?
First of all, you need to realize that there are multiple types of dimples. Facial dimples can occur in the cheeks or on the chin, the latter of which is known as a cleft. Back dimples, or two indentations just above your bottom, have also grown in popularity.
What causes dimples?
The cause of chin dimples is easier to pin down. Right now, most scientists agree that clefts occur when the chin doesn’t fuse correctly when the embryo is forming. Figuring out what causes the indentations in your cheeks, though, is more complicated.
Cheek dimples used to be considered a dominant trait. Now, however, more scientists consider them a genetic abnormality. In particular, dimples occur when a bifid (or double) zygomaticus major muscle exists. The muscle is connected to the cheek when a person smiles, the muscle flexes, causing the dimple to appear deeper and more obvious to the naked eye. If both parents have dimples, the child will likely inherit them.
It’s also important to realize that babies’ dimples may or may not be true dimples. Most infants have cheek indentations because of the excess fat in their cheeks. As they grow older and lose their baby fat, though, uninherited dimples will disappear.
Do dimples have any benefits?
So, does having dimples give you an advantage in any part of your life? Maybe. Although evolutionists aren’t entirely sure why dimples originally developed, they have a few ideas.
For instance, dimples may have been nature’s way of making extra-adorable babies…and therefore encouraging parents to care for their offspring. I mean, how can you not love a baby with super chubby cheeks?
One group of scientists has even suggested that dimples “could be of added value in making an expression noticeable, or in providing information about the intensity of the expression.” Basically? They’re people’s secret weapon to communicate better.
And you only need to consider a few celebrities – from Jennifer Garner to Ariana Grande to Shirley Temple – to realize that dimples are often associated with beauty, youth, and innocence nowadays. If you have back dimples, you can add “sexy” to the list. Some believe that women with back dimples can orgasm easier. Why? The indentations promote good circulation around your pelvis area, which can help with climaxing.
Who knew dimples came with so many benefits?
Can you give yourself dimples?
If dimples are so awesome, is there any research on how to get dimples if you don’t already have them? The truth is, plenty of people have tried to artificially develop dimples before. In fact, the Dimple Machine was invented in 1931 and featured headgear that promised to craft a “fine set of dimples.” And, of course, you only have to google “how to get dimples” to find plenty of YouTube videos on the topic.
However, you’re either born with dimples…or you’re not. True, you can invest in cheek piercings that “fake” dimples by indenting the skin with a small piece of metal. And, in 2012, plastic surgeons revealed a new technique for creating dimples by “tethering” a small area of skin to the facial muscles. (Can you say, “Ow. ”)
If you want an easy way to magically have the cheeks of Shirley Temple, though, that isn’t possible. (At least, not yet). On the flip side, the same can be said for people who want to remove this quirky facial feature. Plastic surgeons say that, even with a facelift, cheek dimples won’t disappear.
The Bottom Line
So what should you (hopefully now) know about dimples? Basically, they’re irregular genetic traits that you either have…or you don’t. Sure, they may come with their share of benefits. However, if you don’t have dimples, don’t worry!
After all, beauty is in the eye of the beholder…and your smile (or your chin…or your back) is perfect as it is, dimples or not.
Causes of Back Dimples - Biology
Dimples: Chances are, if you don't have them, you want them.
Looking at the celebrities smiles of Miranda Kerr and Jennifer Garner, dimples seem to be a facial feature many wish they inherited. We've even heard stories of people using makeup or biting the insides of their mouths in hopes of achieving the popular look.
Dimples can be described as natural facial indentations -- some scientists attribute dimples to the
"shorter muscles near the cheeks," according to Bright Hub. Others believe it's due to variations in the "Zygomaticus major muscle."
But some people want dimples so badly that they are willing to go under the knife for it. "Dimpleplasties" have been on the rise for years, and involve plastic surgeons taking "chunks" from the insides of their patient's cheeks.

As facial dimple surgeries continue to rise, so do dimple surgeries on the lower back. A sign of a "healthy" body, "Venus dimples" sit right at the base of the spine. And just like facial dimples, people are flocking to the plastic surgeon to replicate the indentations of Kendall Jenner and other models.
10 Interesting Facts about Back Dimples
Humans might share an identical physiology but there are certain body characteristics that some have and others don’t, like connected earlobes, dimples, sometimes an extra finger and back dimples. Some of these features are more sought after than others, such as back dimples. They are also known as ‘Dimples of Venus’ and are more common in women. They can reveal a lot about a person including their health. Here are 10 interesting fact about back dimples.
#1. The mark of beauty
Dimples are always cute and back dimples are even more sought after. They have been considered a mark of beauty which is evident from the fact that they were named after Venus- the Roman goddess of beauty.
#2. Not just for women
Even though they are named after a goddess of beauty, back dimples just don’t appear in women. Men can also have back dimples but compared to women, their numbers are rather small.
Back dimples are genetic and are passed down from mothers to their kids.
#4. The scientific reason
Their scientific name is ‘Lateral Lumbar Indentation’ but calling them back dimples seems way more easier. These dimples are formed just above the sacroiliac joints and result from a short ligament that stretches between the skin and spine.
#5. No deformity
Though they are not seen in every human body, they are not a mark of any kind of deformity. And people with back dimples do not have any problems with their spine or any other medical condition.
Women with back dimples are more satisfied sexually because they can climax easily than people who don’t have them. It is because of the positioning of the pelvic bone and the ligaments and a better blood circulation.
#7. Overall good health
There is a connection between one’s fat percentage and good health for back dimples to show up. For males (20-40 years old), a good range of fat percentage is between 8-19%. for women it is 21-31%. the same range is considered good enough for back dimples to become apparent. So if yours don’t show yet, losing some weight might do the trick.
#8. They can be sculpted
Unfortunately, there is no way to get them if you aren’t genetically blessed. And for those who want to sculpt theirs, doing exercises that focus on hips and glutes can help you in defining them more prominently.
Some of the exercises to enhance and sculpt your back dimples include the hip bridge and superman hold.
#10. Better blood flow
It is said that people with back dimples have better blood circulation in their bodies.
Diagnosis and Tests
How do doctors diagnose a sacral dimple?
To diagnose a sacral dimple, a doctor does a physical exam to look at the area near the bottom of the spine. The doctor will note the size and location of the dimple.
For a sacral dimple that looks large, deep, or farther than usual from the crease of the buttocks, a doctor may order an ultrasound test. This test provides images of the spine. Doctors may also order an ultrasound if they see a skin tag, hairy patch, or bruising in the area.
Chin dimples differ from cheek dimples
Not everyone who has facial dimples has them on their cheeks. Some people have what's called cleft chins. Unlike your garden variety chin, cleft chins have a small gap or dimple through the middle. Like cheek dimples, whether or not you have a cleft chin depends on your genetics. If one of your parents has a cleft chin, you have a greater chance of having one too. Although there are definitely similarities between chin and cheek dimples, there are also some pretty big differences.
Dimpled cheeks are the result of a muscular abnormality whereas a chin dimple is actually the result of the malformation of the lower jaw. During typical fetal development, the lower jaw fuses together. A cleft chin results when the jaw does not fully fuse. It may sound a little scary, but — just like cheek dimples — there are no adverse effects. Chin and cheek dimples can exist together as well as separately, and both types of dimples become more apparent when smiling.

Causes and Risk Factors for Sacroiliac Joint Dysfunction
Certain factors can raise the risk of developing sacroiliac dysfunction and pain, including:
- Gait issues, such as leg length discrepancy or scoliosis, which can place uneven pressure on one side of the pelvis, causing wear-and-tear on the SI joint and an increased risk of pain.
- Pregnancy or recent childbirth can commonly cause sacroiliac joint pain in women due to weight gain, hormonal changes causing ligaments in the SI joint to relax (hypermobility), and pelvic changes associated with childbirth. For some women, ligaments may remain loose after childbirth and cause sacroiliac joint pain and instability to continue.
In many cases, sacroiliac joint pain may arise gradually with no obvious cause. Other cases may be the direct result of injury or trauma, such as the jolt from a fall.
