Distal biceps rupture

A distal biceps rupture is not very common but a major injury that puts an impact on the tendon that connects the biceps muscles to the radial tuberosity of the forearm. This rupture occurs because of a sudden and forceful tightening of the biceps muscles against resistance. Most often, such contractions happen while getting involved in activities such as heavy lifting or rapid pulling movement. For proper management, it is important to know about its causes and symptoms.

Causes of distal biceps rupture.

The eccentric contraction of the biceps muscle causes the distal biceps to rupture. Activities that contract the muscles while lengthening, such as while resisting any sudden pull, lead to the rupture of biceps muscles. The tendon can either tear partially or fully in such circumstances. Certain factors enhance the risk of getting distal biceps rupture. These are as follows:

Age

As tendons degenerate over time, ruptures become very common among people aged between 30 and 60 years.

Overuse activities

Repetitive activities or sports that require repeated arm movements can cause weakening of the tendon, thus making it highly prone to injuries.

Use of steroid

The use of anabolic steroids can also make the tendons weak and enhance the chance of getting rupture.

Previous injuries

Any injuries or conditions that have affected the elbow joint can increase the risk of getting tendon tears.

Smoking

Nicotine impairs tendon healing and enhances the risk of getting tendon injuries.

Signs of distal biceps rupture

The signs of the distal biceps rupture are distinctive, such as:

Pain

A sudden and sharp pain in the front part of the elbow or the forearm at the time when the injury occurred.

Popping sound

Some people hear or feel a popping sensation when the tendon is torn.

Feeling weak

Feeling difficulty or being unable to bend the elbow or rotate the forearm in an outward direction is one of the major signs.

A bulge in the upper arm

It is one of the noticeable symptoms of distal biceps rupture. A bulge appears in the upper arm, called the “Popeye sign,” as the biceps muscle retracts.

Treatment

Treatment of distal biceps rupture often relies on many factors, such as how severe the tear is, the inactivity level of the patient and overall health. Options are:

Non-surgical treatment

This is considered for those who have partial tears or patients having low functional demands. It includes rest, application of ice, managing pain and physical therapy for restoration of motion and strength.

Surgical treatment

Most active individuals and those suffering from full tears benefit from surgical intervention. This surgery attaches the affected tendon to the forearms’ radial tuberosity. The two main surgical methods are the single incision technique and the incision technique.

Conclusion

A distal biceps injury is a specific type of injury affecting the tendon that connects the biceps muscle with the bone of the forearm. A sudden and forceful arm movement causes this, and it’s important to recognize the symptoms, make the right diagnosis and receive on-time intervention for optimum recovery. With proper care and rehabilitation, people can expect good outcomes and go back to their pre-injury level.
