Treatment of Undisplaced Fractures Using LLLT/PBMT
Low Level Laser Therapy (LLLT), also known as Photobiomodulation Therapy (PBMT), uses red and near-infrared light applied over targeted areas. In our clinic it is used as part of a GP-led treatment approach for selected undisplaced fractures, delayed healing presentations and associated soft tissue pain after appropriate medical assessment.
PBMT/LLLT is non-invasive and generally well tolerated. Suitability and response vary, and treatment recommendations depend on the diagnosis, severity, duration of symptoms and individual clinical factors. PBMT/LLLT has been studied for a range of musculoskeletal pain and injury conditions. See our references page for supporting literature.
Gentle. Drug-Free. Evidence-Informed
Key Points:
- Undisplaced fractures occur when the bone breaks but the fragments remain aligned, typically requiring stabilisation to ensure proper healing.
- Common sites for undisplaced fractures include the wrist, metatarsals, scaphoid, clavicle, ribs, fibula, hip and vertebral body.
- LLLT/PBMT can be considered as an adjunct treatment for selected fractures that are healing slowly or showing delayed union, after appropriate imaging and medical review.
- Splints, braces and supports are used to immobilise the fracture, keep the bone in alignment and limit movement, providing pain relief and aiding tissue healing.
- LLLT/PBMT does not replace immobilisation, fracture protection, orthopaedic review or surgery where these are required.
- LLLT/PBMT may support the local tissue environment involved in bone and soft tissue repair while avoiding mechanical loading of the injured area.
What are Undisplaced Fractures?
An undisplaced fracture is a type of bone fracture where the bone has cracked or broken, but the fragments remain in near-normal alignment. Unlike displaced fractures, where the bone fragments are misaligned, an undisplaced fracture typically requires less intervention, but still needs to be carefully managed to prevent complications.
The periosteum (the outer membrane of the bone) and the surrounding soft tissues often remain partially intact, which helps to stabilise the fragments and reduce the likelihood of further displacement.
The key principle in treating these fractures is to maintain alignment, protect the fracture and allow natural healing while managing the load placed on the injured area.
Causes of Undisplaced Fractures:
Undisplaced fractures typically occur due to:
- Trauma or sudden impact: A direct blow or fall, such as falling onto an outstretched hand (FOOSH injury).
- Overuse: Repetitive stress on bones from activities such as running, jumping, or other high-impact movements.
- Bone density issues: Conditions such as osteoporosis or osteopenia, where bones are more fragile and prone to fracture under less force.
- Age: Older individuals, particularly those with diminished bone strength, are more susceptible to fractures.
- Sports: Activities such as basketball, tennis, or gymnastics can contribute to repetitive stress and subsequent fractures.
Common Sites Involved:
Undisplaced fractures can occur in several locations throughout the body. Common areas include:
- Wrist (distal radius): Often occurs from low-energy falls, especially in older adults (FOOSH injuries).
- Metatarsals (especially the 5th metatarsal): Typically results from stress fractures or inversion injuries to the foot.
- Scaphoid (wrist): A common site in younger adults due to FOOSH injuries.
- Clavicle: Typically occurs after direct shoulder trauma, often during sports or falls.
- Ribs: May result from blunt chest trauma, intense coughing, or osteoporotic fractures in older individuals.
- Fibula (Weber A ankle fracture): Usually caused by low-energy inversion injuries to the ankle.
- Hip (undisplaced femoral neck fracture): Common in elderly individuals after early-stage falls.
- Vertebral body: Compression fractures in osteoporotic individuals without significant trauma.
- Tibial plateau: Often occurs in elderly individuals due to low-energy valgus stress.
Symptoms of Undisplaced Fractures:
The symptoms of an undisplaced fracture may vary depending on the location and severity of the injury but generally include:
- Pain: Typically, pain is localised to the fracture site and worsens with movement or pressure.
- Swelling: Swelling may occur around the injured area, particularly in the first 24–48 hours.
- Tenderness: The area may be sensitive to touch.
- Bruising: Discoloration may appear over time around the injury site.
- Limited mobility: Difficulty moving the affected limb or joint due to pain or instability.
Diagnosis of Undisplaced Fractures:
Diagnosing an undisplaced fracture involves:
- Medical History: A thorough assessment of how the injury occurred and symptoms experienced.
- Physical Examination: Checking for tenderness, swelling, and bruising around the injury site, as well as assessing the range of motion.
- Imaging: X-rays are typically used to confirm the fracture, though early fractures may be subtle and require follow-up imaging. In some cases, MRI or CT scans may be needed to detect small or hairline fractures.
Undisplaced Fractures – Treatment Overview
Low Level Laser Therapy (LLLT), also known as Photobiomodulation Therapy (PBMT), can be considered as an adjunct treatment for selected undisplaced fractures, delayed healing presentations or associated soft tissue pain after appropriate diagnosis and stabilisation. It may help modulate local inflammatory processes and support the tissue environment involved in bone and soft tissue repair without adding mechanical stress to vulnerable structures.
Why Consider Low Level Laser Therapy (LLLT)?
Many patients present after limited relief from rest, splints, anti-inflammatory medications, cortisone injections or prolonged activity restriction. These standard treatments may temporarily ease symptoms but are not suitable or effective for everyone. Prolonged restriction can also contribute to deconditioning. LLLT/PBMT can be considered where inflammation, micro-trauma or delayed union persist, and where excessive loading may delay recovery.
Why ice, anti-inflammatories, and cortisone may not support long-term recovery. Read more here.
- Prolonged rest or immobility can cause muscle wasting and joint stiffness, leading to weakness, compensatory strain and slower recovery. It does not actively promote tissue repair.
- Surgery is rarely required for undisplaced fractures, but unstable, displaced or high-risk fractures require appropriate orthopaedic assessment and management.
How LLLT Supports Healing
LLLT uses red and near-infrared light and may support:
- Helping modulate inflammation and oxidative stress
- Local circulation and oxygenation
- Lymphatic drainage
- Cellular energy production (ATP)
- Collagen and tissue recovery processes where irritation or delayed repair is present
- Assisting pain reduction without loading or stressing the fracture site or surrounding structures
Non-Invasive and Supported by Research
PBMT/LLLT is non-invasive and generally well tolerated. It has been studied in a range of musculoskeletal pain and injury conditions. Individual responses vary, and outcomes depend on the condition being treated and the stage of recovery. Read more here.

Our Treatment Program
All patients are assessed by Dr Shikha Parmar (GP). Treatment is delivered within a structured six-week program, including:
- Up to 12 LLLT sessions
- Early progress review after the first 6 treatments
- Individualised advice and activity modification
- Guided rehabilitation to support longer-term function
Progress is reviewed during the program. Many patients notice appreciable improvement after the first 6 treatments. If there has not been sufficient improvement by this review point, further treatment may not be recommended.
