Big Toe Arthritis (Hallux Rigidus)

What Causes Hallux Rigidus?

 

Arthritis, in general, results from the gradual wear and tear of the cartilage in joints. The big toe joint, like other joints in the body, has a smooth, protective cartilage layer that allows for pain-free movement. Over time, or due to injury, this cartilage can deteriorate, leading to arthritis. Specific factors that contribute to the development of hallux rigidus include:

​

1. Genetics: If arthritis runs in your family, you might be more prone to developing hallux rigidus.

2. Foot Structure: Abnormal foot anatomy, such as having a long first metatarsal bone or flat feet, can increase stress on the big toe joint.

3. Injury: Trauma to the big toe, such as stubbing or jamming it, can damage the cartilage and lead to arthritis.

4. Overuse: Activities that place repetitive stress on the big toe, such as running or jumping, can contribute to the wear and tear of the joint.

 

Symptoms of Hallux Rigidus

 

Patients with hallux rigidus often experience:

 

- Pain and stiffness in the big toe, especially when walking, standing, or bending the toe.

- Swelling and inflammation around the joint.

- Difficulty wearing certain shoes, particularly those with a narrow toe box or high heels.

- Development of bone spurs, which are bony projections that form along the edges of the joint.

 

Treatment Options

 

Treatment for hallux rigidus depends on the severity of the condition. Here are some options:

 

Non-Surgical Treatments

 

1. Medication: Over-the-counter pain relievers like ibuprofen can help reduce pain and inflammation.

2. Footwear Modifications: Wearing shoes with a wide toe box and stiff soles can alleviate pressure on the big toe. Custom orthotics can also provide additional support.

3. Injections: Corticosteroid injections into the joint can provide temporary relief from pain and inflammation.

 

Surgical Treatments

​

When non-surgical treatments fail to provide relief, surgery may be necessary. One of the most effective surgical options for hallux rigidus is 1st MTPJ fusion.

1st MTPJ Fusion

 

1st MTPJ fusion involves the surgical fusion of the bones in the big toe joint. Here’s what you need to know about the procedure:

 

Why Consider 1st MTPJ Fusion?

 

Fusion surgery is considered when the joint is severely damaged and conservative treatments are no longer effective. It aims to eliminate pain and provide a stable and functional foot.

 

The Procedure

 

During the surgery, the damaged cartilage is removed, and the bones are positioned correctly and fixed together using screws or plates. This allows the bones to grow together, or fuse, creating a single, solid bone.

 

Recovery

 

Recovery from 1st MTPJ fusion typically involves:

 

- Wearing a cast or boot for several weeks to protect the foot and allow the bones to heal.

- Gradual return to weight-bearing activities, guided by your surgeon.

- Physical therapy to regain strength and mobility.

 

Benefits and Risks

 

The main benefit of 1st MTPJ fusion is the elimination of pain and improvement in foot function. However, since the joint is fused, you will lose the ability to bend the big toe. This has an influence on the way you walk, but the vast majority of patients will be able to resume their normal activities without limitation. Potential risks include infection, non-union of the bones, and hardware irritation.

 

Conclusion

 

Hallux rigidus can be a painful and limiting condition, but understanding its causes and treatment options can help you manage it effectively. If you're struggling with symptoms, consult with an orthopaedic surgeon to discuss whether 1st MTPJ fusion or another treatment option is right for you. Your journey to pain-free living could be just around the corner.
