What Is A Hip Bone Spur?
The hip is a ball and socket joint. In some patients, bone spurs can form. This happens when abnormal pressure on the bone causes it to grow. How did this bone spur get there and is this a bad thing that needs to be removed or a good thing that protects the joint? In this patient’s case, he has the most common type of hip bone spur called a “pincer deformity”. This means that abnormal pressure on the outside of the hip has caused the socket to grow a bit. Basically, his hip joint had pressure signals on the outside of the existing hip socket and this caused the joint to grow more of itself. To see how this works, check out a video of one of these pincer spurs forming.
Why do you have a bone spur in your hip?
The upshot? Based on the best research we have, that bone spur in your hip is there for a good reason – to protect your joint and prevent arthritis. That’s not to say that the joint might not need a little help, but removing the bone spur is not a smart idea. We treat these patients first by trying to remediate the biomechanical hip issues that caused the bone spur to form and secondly by helping the joint cartilage remain healthier by injecting highly concentrated platelets or stem cells into the joint.
Why does my hip socket grow?

How much force does a surgeon need to pull on a hip?
Well, that’s not so with this one. First, the surgeon must pull on the hip with 60-100 pounds of force to open the area up for the scope. We’ve seen just this part of the surgery lead to unstable hips as this traction can cause an important stabilizing ligament to be permanently damaged.
Does a bone spur hurt the joint?
So the question is, what happens to patients over time who have this bone spur? Does it damage the joint? Nope. The only study that has looked at this issue over time has shown that in fact, when the hip bone spur is present, it reduces the formation of arthritis and protects the joint. If you’re beginning to think that removing a bone spur may be a bad thing, you’re correct.
Can a hip bone spur be removed?
A Google search of this term shows that many prestigious universities suggest that a hip bone spur causes impingement and it needs to be removed surgically . You would think that’s because we have high-level research studies that compare a real hip bone spur removal surgery to a placebo or fake surgery and then follow the results of these two groups of patients over time. The fact is, not a single medical research study has done this experiment. Regrettably, all of the studies that have been done in this area are low-quality affairs, looking at whether patients who get this invasive surgery report improvement, but without comparing those patients to anything meaningful.

What is the procedure to remove bone spurs?
If simple treatments don't provide adequate relief, a surgical procedure to remove the bone spurs, called an osteoplasty, might be considered. There are two surgical approaches to performing an osteoplasty. Hip arthroscopy: Arthroscopic hip surgery is becoming more common, and the removal of bone spurs can be performed arthroscopically.

What is a bone spur on the hip called?
The hip joint is a ball-and-socket joint, and bone spurs can occur on either the ball or the socket of the hip. These bone spurs are called cam or pincer lesions of the hip. 1 . Cam lesion: A cam lesion occurs when the bone spur is on the ball of the hip joint, the top of the thigh bone.
Can a bone spur be removed from the hip?
This is a question of great debate. 2 Although this procedure can reduce pain from FAI, there has been no long- term study to demonstrate that removing bone spurs around the hip joint will help to slow the progression of arthritis. Osteoplasty is often performed in combination with other procedures in the hip to address the labrum. Studies are ongoing to determine the long-term benefits of procedures used to treat FAI.
