Hand & Wrist Anatomy

The hand and wrist are intricate structures that allow for a wide range of motion and dexterity. Comprised of bones, muscles, tendons, ligaments, and nerves, they work together to perform everyday tasks with precision and strength. The wrist contains eight small bones, known as carpals, while the hand consists of 27 bones, including the metacarpals and phalanges. Ligaments and tendons provide stability and movement, while nerves control sensation and fine motor skills. Understanding the anatomy of the hand and wrist is essential for diagnosing and treating injuries, from fractures to carpal tunnel syndrome.

Hand and Wrist Arthritis: Causes, Types, and Symptoms

Arthritis in the hand and wrist occurs when the cartilage in the joints breaks down, leading to pain, swelling, and limited mobility. This can make everyday tasks like gripping, typing, or even turning a doorknob difficult. Understanding the causes and types of hand and wrist arthritis is key to finding the right treatment and managing your symptoms.

What Causes Hand and Wrist Arthritis?

Arthritis in the hand and wrist can develop for several reasons, and the type of arthritis is closely linked to its cause. Here’s a look at the most common causes, and how they lead to different types of arthritis:

  1. Osteoarthritis (OA):
    • Cause: Over time, repetitive movements and aging cause cartilage in the joints to wear down. This gradual breakdown of cartilage leads to joint pain and stiffness.
    • Type: OA is the most common type of hand and wrist arthritis, often affecting the base of the thumb, fingers, and wrist. It typically occurs in older adults and those who use their hands frequently.
  2. Rheumatoid Arthritis (RA):
    • Cause: RA is an autoimmune condition where the body’s immune system mistakenly attacks the lining of the joints, causing inflammation.
    • Type: RA can cause severe pain, swelling, and deformities, often affecting both wrists and fingers. It is most common in people aged 30-60 and tends to develop more quickly than OA.
  3. Post-Traumatic Arthritis:
    • Cause: After an injury, such as a fracture or ligament tear, the damaged cartilage can accelerate the development of arthritis in the joint.
    • Type: This type of arthritis develops in the affected joint after an injury, often causing long-term pain and stiffness in the hand or wrist.
  4. Psoriatic Arthritis:
    • Cause: Linked to the skin condition psoriasis, psoriatic arthritis occurs when inflammation affects the joints, often in people with a family history of psoriasis.
    • Type: This form of arthritis can affect the hand and wrist, causing pain, swelling, and reduced mobility, and can sometimes lead to joint deformities.
  5. Gout:
    • Cause: Gout is caused by a buildup of uric acid crystals in the joints, often due to diet or metabolism issues.
    • Type: While gout commonly affects the big toe, it can also impact the wrist and hand, causing sudden, severe pain and swelling, often in one joint at a time.

Symptoms of Hand and Wrist Arthritis

Types of Cysts in the Hand and Wrist

There are a few different types of cysts that can form in the hand and wrist. Here are the most common ones:

  1. Ganglion Cysts:
    • What it is: The most common type of cyst in the hand and wrist, often found on the back of the wrist or at the base of the fingers. These cysts are filled with a thick, jelly-like fluid and typically appear as smooth, rounded lumps.
    • Symptoms: A visible lump, pain or discomfort when pressing on the cyst, limited mobility of the wrist or finger.
  2. Mucous Cysts:
    • What it is: These cysts usually appear near the base of the fingers or around the nail. They are often connected to osteoarthritis and form when fluid accumulates in the joint.
    • Symptoms: A visible lump, pain or sensitivity near the base of the finger, and possibly a noticeable change in nail appearance.
  3. Synovial Cysts:
    • What it is: Synovial cysts occur when the synovial membrane, which lubricates the joints, bulges out, creating a fluid-filled sac. They often develop near joints or tendons.
    • Symptoms: A soft, movable lump near the joint, pain or discomfort when using the affected joint.
  4. Tendon Sheath Cysts (Tendon Cysts):
    • What it is: These cysts form along the tendons, often in the wrist or fingers. They are usually smaller than ganglion cysts and can be more tender to the touch.
    • Symptoms: Pain when moving the finger or wrist, swelling, and sometimes a visible lump.

Common Symptoms of Cysts in the Hand and Wrist

While many cysts don’t cause significant symptoms, others can cause discomfort or impair movement. Here are some common signs of cysts in the hand and wrist:

  • Visible Lump or Swelling: A cyst often appears as a round, soft lump that can vary in size. It might be more noticeable when the wrist or hand is in certain positions.
  • Pain or Discomfort: Cysts can cause mild to moderate pain, especially if they press on nerves or joints. The pain may be more noticeable when the cyst is touched or during movement.
  • Stiffness or Limited Movement: Depending on the size and location, a cyst can restrict the range of motion in the wrist or fingers, making it harder to grip or bend.
  • Tenderness: Cysts, especially ganglion cysts, can be tender to the touch. Some people experience soreness or discomfort when pressure is applied to the cyst.
  • Changes in Appearance: Some cysts, particularly mucous cysts, can affect the appearance of the nails or cause the skin to look stretched or discolored around the cyst.

When to Seek Help

While most cysts are harmless and do not require treatment, it’s important to see a doctor if you experience any of the following:

  • Persistent pain or swelling that doesn’t improve over time.
  • Difficulty moving the wrist or fingers due to the cyst.
  • If the cyst grows rapidly or changes in appearance.
  • If you notice other concerning symptoms like redness, warmth, or fever, which could indicate an infection.

A healthcare provider can assess the cyst, determine whether it requires treatment, and discuss options like aspiration (draining the fluid), corticosteroid injections, or surgery, depending on the size, location, and symptoms of the cyst.

Cysts of the hand and wrist are common and often benign, but they can cause discomfort and restrict movement. Recognizing the symptoms and understanding the types of cysts can help you address the issue early and seek appropriate care. If you experience pain, swelling, or other signs of a cyst in your hand or wrist, don’t hesitate to reach out to a healthcare provider for evaluation and treatment.
