ICD-10: S62.21

Bennett's fracture, classified under ICD-10 code S62.211A, is a specific type of fracture that occurs at the base of the first metacarpal bone, which is the bone in the hand that supports the thumb. This injury is characterized by a fracture that is intra-articular, meaning it extends into the joint surface, and is often associated with a fracture-dislocation of the carpometacarpal (CMC) joint of the thumb.

Clinical Description

Mechanism of Injury

Bennett's fracture typically results from a direct impact or axial loading to the thumb, such as during a fall or a punch. The mechanism often involves a forceful impact that causes the metacarpal to fracture at the base, leading to a characteristic fracture pattern that can be unstable due to the involvement of the joint.

Symptoms

Patients with Bennett's fracture may present with:
- Pain and Swelling: Localized pain at the base of the thumb, often accompanied by swelling.
- Deformity: Visible deformity of the thumb, which may appear shortened or misaligned.
- Limited Range of Motion: Difficulty in moving the thumb, particularly in opposition and grasping.
- Bruising: Discoloration around the injury site may develop over time.

Diagnosis

Diagnosis is primarily made through clinical examination and imaging studies. X-rays are essential to confirm the fracture and assess its displacement. The fracture may show a characteristic "bite" or "saddle" appearance on imaging, indicating the intra-articular nature of the injury.

Treatment Options

Non-Surgical Management

In cases where the fracture is non-displaced or minimally displaced, conservative treatment may be sufficient. This typically includes:
- Immobilization: The use of a splint or cast to immobilize the thumb and allow for healing.
- Pain Management: Non-steroidal anti-inflammatory drugs (NSAIDs) may be prescribed to manage pain and inflammation.

Surgical Intervention

Surgical treatment is often required for displaced fractures or those that are unstable. Surgical options may include:
- Open Reduction and Internal Fixation (ORIF): This procedure involves realigning the fractured bone fragments and securing them with screws or plates.
- Percutaneous Pinning: In some cases, pins may be used to stabilize the fracture without the need for a larger incision.

Prognosis

The prognosis for Bennett's fracture is generally good, especially with appropriate treatment. However, complications such as arthritis or stiffness in the CMC joint can occur if the fracture is not properly managed. Rehabilitation and physical therapy are often recommended post-treatment to restore function and strength to the thumb.

Conclusion

Bennett's fracture is a significant injury that requires careful assessment and management to ensure optimal recovery. Understanding the clinical presentation, treatment options, and potential complications is crucial for healthcare providers in delivering effective care for patients with this type of fracture. Proper diagnosis and timely intervention can lead to favorable outcomes, allowing patients to regain full function of their thumb.

Bennett's fracture, classified under ICD-10 code S62.21, is a specific type of fracture that occurs at the base of the first metacarpal bone, typically resulting from an axial load on a flexed thumb. This injury is characterized by a fracture-dislocation of the carpometacarpal (CMC) joint of the thumb, often leading to significant functional impairment if not treated properly. Here, we will explore the standard treatment approaches for Bennett's fracture, including both non-surgical and surgical options.

Non-Surgical Treatment

1. Immobilization

• Splinting: The initial treatment often involves immobilizing the thumb and wrist using a splint or cast. This helps to stabilize the fracture and prevent further displacement. A thumb spica splint is commonly used, which allows for immobilization of the thumb while permitting some movement of the fingers[1].
• Duration: Immobilization typically lasts for 4 to 6 weeks, depending on the severity of the fracture and the patient's healing response[2].

2. Pain Management

• Medications: Nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen or naproxen are often prescribed to manage pain and reduce inflammation during the healing process[3].

3. Physical Therapy

• Rehabilitation: Once the fracture has stabilized, physical therapy may be recommended to restore range of motion, strength, and function. This can include exercises to improve thumb mobility and grip strength[4].

Surgical Treatment

1. Indications for Surgery

• Surgery is typically indicated for Bennett's fractures that are significantly displaced or unstable, where non-surgical methods may not adequately restore alignment or function[5].

2. Surgical Techniques

• Open Reduction and Internal Fixation (ORIF): This is the most common surgical approach for Bennett's fractures. The procedure involves making an incision to access the fracture site, realigning the bone fragments, and securing them with screws or plates[6].
• Percutaneous Pinning: In some cases, especially for less complex fractures, percutaneous pinning may be used. This involves inserting pins through the skin to stabilize the fracture without a large incision[7].

3. Postoperative Care

• Immobilization: After surgery, the thumb may be immobilized in a splint for several weeks to allow for proper healing.
• Follow-Up: Regular follow-up appointments are essential to monitor healing through X-rays and to adjust treatment as necessary[8].

Conclusion

The treatment of Bennett's fracture is tailored to the individual based on the fracture's characteristics and the patient's overall health. Non-surgical methods are effective for stable fractures, while surgical intervention is reserved for more complex cases. Regardless of the treatment approach, early intervention and appropriate rehabilitation are crucial for optimal recovery and restoration of thumb function. If you suspect a Bennett's fracture, it is essential to seek medical attention promptly to ensure the best possible outcome.
