What is Medial Subluxation?

Medial subluxation is a condition that many people don’t fully understand. It happens when a joint partially slips out of place toward the middle of the body. Unlike a full dislocation, where the joint completely comes apart, a subluxation means the bones involved are only partly displaced. This subtle difference matters because the symptoms can be tricky to spot. Medial subluxation often causes discomfort and instability, affecting daily activities. Knowing what it is, how it happens, and what to do about it can help you get the right care and avoid long-term problems.

What You Need to Know About Medial Subluxation

Subluxation refers to a partial dislocation. When we say medial subluxation, it means the joint moves partially toward the midline of the body. For example, in the wrist, this often involves the distal radioulnar joint, where the two forearm bones—the radius and ulna—meet near the wrist. In the knee, medial subluxation can involve the kneecap sliding partially toward the inside of the leg. These joints rely on ligaments and other tissues to keep them aligned. When those supports weaken or are damaged, the bones can slip out of their usual track.

Anatomy Behind Medial Subluxation

To understand medial subluxation, it helps to know which parts of the body are involved. The wrist contains two main forearm bones, the radius on the thumb side and the ulna on the little finger side. These bones are connected by ligaments and a cartilage structure called the articular disk, which allows smooth movement. In the knee, the kneecap sits in a groove on the thigh bone, held in place by ligaments on both sides. When the ligaments or tendons supporting these bones become loose, injured, or cut during surgery, the bones can shift partially from their normal positions.

Common Causes of Medial Subluxation

Medial subluxation can happen in many ways. It may be caused by trauma, such as falling onto an outstretched hand, which puts pressure on the wrist joints. Forceful twisting motions like oversupination (palm turning upwards) or overpronation (palm turning downwards) also contribute. Sometimes, the injury results from repetitive stress in sports like golf, gymnastics, or racket sports. Surgery to correct other joint problems can unintentionally damage stabilising ligaments, causing medial instability. In some cases, ligament looseness or untreated previous injuries leave the joint unstable, making subluxation more likely.

Symptoms You Might Notice

The symptoms of medial subluxation can vary depending on how severe the joint displacement is. Common signs include:

• Pain around the joint, especially after an injury
  
• Swelling and tenderness in the affected area
  
• A visible deformity or a bump where the bone has shifted
  
• A sensation that the joint is unstable or might give way
  
• Difficulty or pain when moving the joint, such as turning the wrist or bending the knee
  
• Popping or clicking sounds during movement
  
  

These symptoms often interfere with everyday activities and should prompt a visit to a healthcare professional.

How Is Medial Subluxation Diagnosed?

Because medial subluxation can be subtle, doctors rely on a combination of patient history, physical examination, and imaging tests. The physical exam involves feeling around the joint for tenderness and checking how stable it feels when moved. Doctors will also watch your movement and ask about your symptoms. Imaging is crucial. X-rays reveal bone alignment and any fractures. MRI scans show soft tissue damage, such as ligament tears, and CT scans give detailed views of bones and joints. A proper diagnosis helps guide treatment and recovery.

Treatment Options for Medial Subluxation

Treatment depends on how bad the subluxation is and how it affects your daily life. Most doctors start with non-surgical options:

• Rest and avoiding activities that cause pain
  
• Applying ice to reduce swelling
  
• Using a brace or splint to immobilise and support the jointTaking anti-inflammatory medications to relieve pain
  
• Engaging in physical therapy to strengthen muscles and improve joint stability
  
  

If symptoms persist or the subluxation keeps happening, surgery may be necessary. Surgical options include repairing or reconstructing damaged ligaments, realigning bones, or reconstructing supporting soft tissues. Recovery from surgery usually involves a period of immobilisation followed by rehabilitation exercises to regain strength and motion.

Possible Complications of Medial Subluxation

If left untreated, medial subluxation can cause several problems over time. Repeated slipping of the joint can lead to damage of the cartilage. This increases the risk of arthritis. Chronic instability may make it difficult to perform normal activities. Also may increase the chance of a full dislocation. In severe cases, the displaced joint can press on nearby nerves or blood vessels. Which can cause numbness or circulation issues. Early treatment is important to prevent these complications and maintain joint health.

Preventing Medial Subluxation

While some causes of medial subluxation cannot be avoided, you can reduce your risk by taking certain steps. Strengthening the muscles around your joints through regular exercise helps keep bones stable. Wearing protective gear during sports can prevent injuries. If you have had a previous subluxation or surgery, using a brace as recommended by your doctor can provide extra support. Always follow your healthcare provider’s advice about rehabilitation and avoid rushing back into high-impact activities too soon.

Wrist Braces for Medial Subluxation

Wrist braces help support and protect your wrist when you have medial subluxation. They keep the joint stable and prevent it from moving too much. This helps reduce pain and swelling while the ligaments heal.

Some braces are stiff to keep your wrist still, while others allow some movement but still provide support. Your doctor will recommend the best type for you.

Wearing a wrist brace as directed helps your wrist recover faster. Over time, you can use it less and start exercises to strengthen your wrist. Wrist braces are a simple and effective way to aid healing and prevent further injury.

For medial subluxation of the wrist, TFCC Support Wrist Brace is an excellent choice. It provides targeted support to stabilise the wrist bones while allowing comfortable movement. This brace helps reduce pain and promotes healing, making it ideal for managing wrist instability.

When to See a Doctor

If you experience sudden joint pain, swelling, or notice a deformity, it is important to get medical attention promptly. Also, if your joint feels unstable, gives way, or you have difficulty moving it normally, these are signs you should see a healthcare professional. Early diagnosis and treatment improve the chances of a full recovery and prevent further damage. Never try to self-diagnose or push through pain without expert advice.

Conclusion

Medial subluxation is a partial slipping of a joint that can cause pain, instability, and difficulty in movement. It often affects the wrist and knee but can involve other joints. Understanding the symptoms and causes helps you seek timely care. Treatment ranges from rest and braces to surgery, depending on severity. Preventative measures and proper rehabilitation play a big role in recovery. If you suspect medial subluxation, seeing a healthcare provider early is the best way to protect your joint health for the future.
