The Role of Laser Therapy in Clavicle Fracture Healing

Clavicle fractures, also known as collarbone fractures, are a common injury that can occur due to various reasons such as falls, sports injuries, or motor vehicle accidents. These fractures can cause significant pain and discomfort, and proper healing is essential to restore normal function and prevent long-term complications. In recent years, laser therapy has emerged as a potential treatment option for accelerating the healing process of clavicle fractures. This article explores the role of laser therapy in clavicle fracture healing, discussing its mechanism of action, benefits, limitations, and current research findings.

The Basics of Clavicle Fractures

Before delving into the role of laser therapy in clavicle fracture healing, it is important to understand the basics of clavicle fractures. The clavicle is a long bone that connects the shoulder blade to the sternum, forming part of the shoulder girdle. It is susceptible to fractures due to its exposed position and the forces it experiences during various activities.

Clavicle fractures can be classified into three main types: midshaft fractures, lateral fractures, and medial fractures. Midshaft fractures are the most common type, accounting for approximately 80% of all clavicle fractures. Lateral fractures occur near the shoulder joint, while medial fractures occur near the sternum.

Common symptoms of clavicle fractures include pain, swelling, bruising, and difficulty moving the affected arm. Diagnosis is typically made through physical examination, X-rays, and sometimes additional imaging tests such as CT scans or MRI.

The Role of Laser Therapy in Clavicle Fracture Healing

Laser therapy, also known as low-level laser therapy (LLLT) or photobiomodulation therapy, is a non-invasive treatment modality that uses low-intensity laser or light-emitting diodes (LEDs) to stimulate cellular activity and promote tissue healing. It has been widely used in various medical fields, including orthopedics, for its potential to enhance the healing process.

The mechanism of action of laser therapy in clavicle fracture healing is not fully understood, but it is believed to involve several biological processes. Laser therapy stimulates the production of adenosine triphosphate (ATP), the energy currency of cells, leading to increased cellular metabolism and protein synthesis. This, in turn, promotes tissue repair and regeneration.

Furthermore, laser therapy has been shown to have anti-inflammatory effects by reducing the production of pro-inflammatory cytokines and increasing the release of anti-inflammatory cytokines. This can help reduce pain, swelling, and inflammation associated with clavicle fractures.

Benefits of Laser Therapy in Clavicle Fracture Healing

Laser therapy offers several potential benefits in the healing of clavicle fractures. Some of the key benefits include:

  • Accelerated healing: Laser therapy has been shown to promote the proliferation of osteoblasts, the cells responsible for bone formation, and enhance the mineralization of newly formed bone. This can lead to faster healing of clavicle fractures and earlier restoration of normal function.
  • Pain relief: Laser therapy has analgesic properties and can help reduce pain associated with clavicle fractures. It achieves this by inhibiting the transmission of pain signals and stimulating the release of endorphins, the body’s natural painkillers.
  • Reduced inflammation: Laser therapy’s anti-inflammatory effects can help reduce swelling, redness, and inflammation in the fractured clavicle. This can improve patient comfort and facilitate the healing process.
  • Non-invasive and safe: Laser therapy is a non-invasive treatment option that does not involve the use of drugs or surgery. It is generally considered safe when performed by trained professionals and has minimal side effects.

Limitations and Considerations

While laser therapy shows promise in clavicle fracture healing, it is important to consider its limitations and potential contraindications. Some of the limitations and considerations include:

  • Variable effectiveness: The effectiveness of laser therapy in clavicle fracture healing may vary among individuals. Factors such as the severity of the fracture, patient age, overall health, and compliance with treatment protocols can influence the outcomes.
  • Optimal dosage and timing: The optimal dosage and timing of laser therapy for clavicle fractures are still being investigated. Different parameters such as laser power, wavelength, treatment duration, and frequency may affect the therapeutic outcomes.
  • Contraindications: Laser therapy may not be suitable for individuals with certain medical conditions, such as cancer, epilepsy, or pregnancy. It is important to consult with a healthcare professional to determine if laser therapy is appropriate in specific cases.
  • Cost and availability: Laser therapy may not be widely available in all healthcare settings and can be costly. Insurance coverage for laser therapy in clavicle fracture healing may vary, and out-of-pocket expenses should be considered.

Current Research and Clinical Evidence

Research on the role of laser therapy in clavicle fracture healing is still relatively limited, and more high-quality studies are needed to establish its efficacy and optimal protocols. However, some studies have shown promising results:

  • A study published in the Journal of Orthopaedic Surgery and Research found that laser therapy significantly reduced pain and improved functional outcomes in patients with clavicle fractures compared to a control group.
  • Another study published in Lasers in Medical Science reported that laser therapy accelerated the healing process of clavicle fractures by promoting bone formation and reducing inflammation.
  • A systematic review and meta-analysis published in Photomedicine and Laser Surgery concluded that laser therapy had a positive effect on pain relief and functional recovery in patients with bone fractures, including clavicle fractures.

While these studies provide preliminary evidence of the potential benefits of laser therapy in clavicle fracture healing, more research is needed to validate these findings and determine the optimal treatment protocols.


Laser therapy holds promise as a non-invasive treatment modality for accelerating the healing process of clavicle fractures. Its ability to stimulate cellular activity, promote tissue repair, reduce inflammation, and provide pain relief makes it an attractive option for patients with clavicle fractures. However, further research is needed to establish its efficacy, optimal protocols, and long-term outcomes. As with any medical treatment, it is important to consult with a healthcare professional to determine the most appropriate treatment approach for individual cases.

In conclusion, laser therapy has the potential to play a significant role in clavicle fracture healing. Its benefits in terms of accelerated healing, pain relief, and reduced inflammation make it a promising adjunctive treatment option. However, more research is needed to fully understand its mechanism of action, determine optimal treatment parameters, and establish its long-term effectiveness. With further advancements in laser technology and increased research efforts, laser therapy may become a standard part of the treatment protocol for clavicle fractures, improving patient outcomes and quality of life.
