Many people worry as soon as they notice a bump under their skin that wasn't there before. While most of them aren't actually malignant or cancerous, they can be bothersome and cause discomfort.
Carpal boss is a lump that appears on the back of the hand. And, these protrusions might need surgery, depending on the diagnosis of orthopedic surgery specialists in Suffolk County, NY. Learn more about them by reading on.
A Closer Look at Carpal Boss
In medicine, carpals refer to the group of bones that make up the wrist. So, when a person has an abnormality in this part of the body, orthopedic surgeons use the term to describe where it is. This is also true for conditions such as carpal tunnel syndrome, carpal bone hypoplasia, and carpal arthritis. They all occur at the joint connecting your hand and forearm.
The word boss is a medical term, as well. It refers to a protuberant or circumscribed part of the body. It isn't only a cyst or bony lump but can also be a bump on the back of people with severe kyphosis, or the bulge on the neck caused by a goiter.
To put that all together, a carpal boss is a bony prominence, typically on the back of your hand where the carpal and the metacarpal bones meet. It rarely causes serious pain, but the lump is sometimes tender to the touch and can be bothersome when you move your wrist.
Symptoms and Differential Diagnosis
Most people don't show any symptoms of carpal boss aside from the immovable, firm lump on the back of their wrists. However, these bumps can also be caused by similar conditions, so it's best to learn how you can tell them apart. Here are some cases commonly confused with these bulges.
- Ganglion Cyst: At a glance, a carpal boss and ganglion cyst look alike, and they're usually found at the same site. However, the latter feels softer and less firm since it contains a jelly-like fluid instead of a bony substance. It rolls between the fingers, and it typically doesn't cause any pain.
- Subcutaneous Calcification: People with subcutaneous calcification have bumps on their skin, too, but theirs are smaller, appear lighter, and are irregularly shaped. It's caused by a buildup of insoluble calcium salts under the epidermis. There is currently no treatment for this condition.
- Malignant Wrist Tumors: In rare cases, cancerous tumors can also be found in the wrist. They grow quickly and can be very painful, especially at night. It's often caused by a malignancy that has spread from a tumor from another part of the body.
Causes and Risk Factors
Researchers have yet to pin down the exact cause of carpal boss, but they believe it's related to certain conditions, including osteoarthritis, wrist overuse, joint trauma, and congenital issues. The formation typically strikes at age 40 and above for both men and women.
Diagnosis and Treatment
As an orthopedic surgeon checks the lump at the back of your hand, they'll ask questions like when you first noticed it and how it affects your daily activities. They'll also feel the bump and try to move it around. They have to check if it's soft like a cyst or as hard as a tumor or bony structure. This will aid them in diagnosing your condition and help them determine if you need surgery.
If you feel a lot of pain when the doctor touches the lump or moves your wrist, they'll take an X-ray photo of your hand. While the resulting image doesn't show cysts, it helps medical professionals rule out certain conditions that cause discomfort and limit joint movements, such as gout and bone tumors.
Conservative measures, like taking pain relievers and applying a cold compress to the site of the malformation, provide relief most of the time. But, when they don't, you can consider having the boss removed via surgery. It's definitely a safe alternative.
