Colles Fracture

What is a Colles Fracture?

A Colles fracture is a fracture in the distal radius that occurs just above the wrist joint, typically caused by falling onto an outstretched hand. It is characterised by a distal radius fracture with dorsal angulation and often dorsal displacement of the distal fragment, causing the wrist to appear “dinner fork” or “bayonet” shaped. This fracture commonly occurs in older adults, particularly those with osteoporosis, but can affect individuals of all ages.

How Common Are Colles Fractures?

Colles fractures are one of the most common types of wrist fractures. They account for about 15% of all fractures in adults, particularly among post-menopausal women. They are prevalent in older adults due to age-related bone density loss, but younger individuals can also sustain these fractures through sports injuries or falls.

Anatomy of the Wrist in Relation to Colles Fractures

The anatomy of the wrist includes several key structures relevant to Colles fractures:

  • Radius:
    • The radius is one of the two long bones in the forearm (the other being the ulna). A Colles fracture specifically involves the distal radius near the wrist joint.
    • The distal end of the radius is broad and has a unique structure, including the styloid process, which is a bony prominence on the lateral side of the wrist.
  • Ulna:
    • The ulna is one of the long bones in the forearm (the other being the radius) and contributes to the wrist joint, especially at its distal end. Although a Colles fracture primarily involves the radius, the position and stability of the ulna are relevant, particularly concerning the distal radioulnar joint (DRUJ).
  • Carpal Bones:
    • The carpal bones comprise eight small bones that make up the wrist. They articulate with the distal ends of the radius and ulna, forming the wrist joint. The carpal bones are crucial for wrist mobility and stability.
  • Soft Tissues:
    • Ligaments, tendons, and the triangular fibrocartilage complex (TFCC) play significant roles in wrist stability. Injury to these structures can accompany a Colles fracture and may affect recovery and function.
  • Articular Surface:
    • The distal radius’s articular surface interacts with the carpal bones, allowing wrist movement. Displacement or misalignment from a Colles fracture can significantly affect wrist function and range of motion.

Understanding the wrist anatomy is essential for diagnosing and managing Colles fractures and planning effective treatment and rehabilitation strategies.

Symptoms and Causes of Colles Fracture

What Causes a Colles Fracture?

A Colles fracture is typically caused by falling onto an outstretched hand (FOOSH injury), where the person tries to break their fall with their wrist in an extended position. The force from the fall transmits through the wrist, causing a fracture in the distal radius. Other causes may include:

  • Direct trauma: A direct blow to the wrist can lead to a Colles fracture.
  • Sports injuries: Activities involving high impact or falls, such as skiing, skateboarding, or contact sports, can increase the risk.
  • Osteoporosis: Weakened bones can fracture more easily with minimal trauma.

Risk Factors for Colles Fractures

  • Age: Older adults, particularly women post-menopause, are at higher risk due to decreased bone density.
  • Osteoporosis: Conditions that weaken bones, such as osteoporosis, significantly increase the likelihood of fractures.
  • Previous wrist fractures: A history of wrist fractures may predispose individuals to future fractures.
  • Gender: Women are more likely to experience Colles fractures, especially after menopause.
  • Certain sports or activities: Involvement in high-risk sports increases the likelihood of falls and trauma to the wrist.
  • Poor balance or coordination: Individuals with compromised balance may be more prone to falls, leading to fractures.

Common Symptoms of a Colles Fracture

  • Pain and tenderness: Severe pain in the wrist, particularly at the distal radius, is common immediately after the injury.
  • Swelling and bruising: Swelling and bruising near the wrist may develop rapidly.
  • Deformity: Due to dorsal angulation, the wrist may appear deformed, often described as a “dinner fork” or “bayonet” appearance.
  • Limited range of motion: Difficulty moving the wrist and fingers may occur due to pain and swelling.
  • Numbness or tingling: Patients may get numbness or a tingling sensation in the fingers if nerves are affected.

If you are experiencing any of these, contact Access Ortho today for an urgent appointment. Access Ortho is a private fracture clinic in Brisbane and Ipswich that specialises in musculoskeletal injuries.

Potential Complications of Untreated Colles Fractures

  • Malunion: Improper healing of the fracture can lead to misalignment and long-term pain or dysfunction.
  • Nonunion: In some cases, the fracture may fail to heal correctly, leading to chronic pain and instability.
  • Complex Regional Pain Syndrome (abbreviated as CRPS): A chronic pain condition may develop following injury, characterised by severe pain, swelling, and alterations in skin colour.
  • Loss of wrist function: Untreated fractures can lead to reduced range of motion and grip strength, which can affect daily activities.
  • Arthritis: Joint surfaces may become damaged over time, leading to post-traumatic arthritis and long-term discomfort.
  • Nerve damage: If the fracture affects nearby nerves, this can lead to permanent numbness or weakness in the hand.

Timely diagnosis and treatment of a Colles fracture helps to prevent these complications and ensure proper healing. Contact Access Ortho for a rapid orthopaedic appointment.

Diagnosis and Tests for Colles Fracture

How Are Colles Fractures Diagnosed?

Colles fractures are typically diagnosed through a detailed medical history, physical examination, and x-rays. When a patient presents with wrist pain and swelling following a fall, especially with visible deformity, a healthcare provider will assess for a Colles fracture and consider other fracture types.

  • Medical History: The medical practitioner will determine how the injury occurred, the nature of the pain, and any previous wrist injuries.
  • Physical Examination: The physician will assess the wrist for:
    • Swelling, bruising, or deformity.
    • Tenderness over the distal radius.
    • Range of motion and grip strength.
    • Possible neurovascular status to check for nerve or blood vessel damage.

Imaging Tests Used to Confirm a Colles Fracture

  • X-rays:
    • X-rays are the primary imaging modality used to diagnose a Colles fracture. They can confirm the presence of a fracture and assess its type and alignment.
    • Standard X-rays of the wrist usually include both the anteroposterior (AP) and lateral views to evaluate the fracture’s characteristics.
  • CT Scan:
    • In complex cases or when there is uncertainty regarding the fracture’s extent or involvement of adjacent structures, a CT scan may be ordered to provide a more detailed view of the bone and joint anatomy.
  • MRI:
    • While not commonly used for diagnosing Colles fractures, an MRI may be employed if there is suspicion of associated soft tissue injuries (like TFCC tears) or if there are complications in healing.

Differentiating Colles Fractures from Other Wrist Injuries

Although the treatment for different wrist fractures may be similar in many cases, it is essential to differentiate between them to ensure appropriate care and minimise complications. Access Ortho is an Orthopaedic Specialist clinic that provides expert care in the diagnosis and care of fractures.

  • Distal Radius Fracture:
    • A Colles fracture is a fracture in the distal radius characterised by dorsal angulation. Other distal radius fractures may present differently, such as with volar angulation (Smith fractures).
  • Ulnar Styloid Fracture:
    • An ulnar styloid fracture may occur simultaneously with a Colles fracture. While both injuries involve the wrist, the ulnar styloid fracture involves the distal ulna and can affect wrist stability.
  • Scaphoid Fracture:
    • Scaphoid fractures often result from the same mechanism (FOOSH injury) but present with pain in the anatomical snuffbox. Unlike Colles fractures, they may not always be immediately visible on X-ray and may require follow-up imaging.
  • Triangular Fibrocartilage Complex (TFCC) Injury:
    • Injuries to the TFCC may accompany Colles fractures, presenting with similar wrist pain but often accompanied by clicking or instability. MRI is helpful in diagnosing TFCC injuries.
  • Carpal Fractures:
    • Fractures of the carpal bones may also occur due to the same injury mechanism. The specific location of pain, swelling, and tenderness helps differentiate them from Colles fractures.
  • Ligament Injuries:
    • Ligament injuries, such as wrist sprains, may mimic the symptoms of a Colles fracture. Careful assessment of pain patterns and imaging can help distinguish these conditions.

Accurate diagnosis helps determine the appropriate treatment plan and prevent complications associated with wrist injuries. Access Ortho is a specialist Orthopaedic clinic for fractures, sprains and strains. 

Specific Considerations for Colles Fracture

Colles Fracture in Elderly Patients

  • Bone Density:
    • Older adults often have decreased bone density due to osteoporosis, making them more susceptible to fractures with minimal trauma, such as falls.
  • Fall Prevention:
    • Emphasising fall prevention strategies, such as home modifications and balance training, is crucial in this population to reduce the risk of Colles fractures.
  • Treatment Considerations:
    • Surgical intervention may be more common in elderly patients, especially if there is significant displacement or instability. Non-surgical options may be considered if there are concerns regarding the patient’s overall health and functional status.
  • Rehabilitation:
    • Older patients may require a longer rehabilitation period due to pre-existing conditions, frailty, or comorbidities, which can impact recovery and overall functional outcomes.
  • Complications:
    • Older adults may be more at risk of complications such as malunion, nonunion, and the development of post-traumatic arthritis due to age-related changes in healing.

Colles Fracture in Children (Paediatric Considerations)

  • Growth Plates:
    • Assessing for potential involvement of growth plates (physis) near the distal radius is essential in children. A fracture that affects the growth plate may impact future bone growth and should be carefully evaluated.
  • Fracture Patterns:
    • Colles fractures in children may not always present with the typical dorsal angulation seen in adults. They may be more flexible and can sometimes heal without significant intervention.
  • Treatment:
    • Most Colles fractures in children can be treated conservatively with splinting or casting. Surgical intervention is less common and is usually reserved for severely displaced fractures.
  • Rehabilitation:
    • Children generally have a good healing capacity and often return to normal activities sooner than adults. However, monitoring for stiffness or weakness is essential during recovery.
  • Education:
    • Educating children and parents about the importance of safety measures and injury prevention can help reduce the risk of fractures in this age group.

Management and Treatment of Colles Fracture

Non-Surgical Treatment Options for Colles Fractures

  • Immobilisation:
    • Casting: A cast is typically applied to immobilise the wrist and allow for proper healing. It is usually kept on for about 4 to 6 weeks, depending on the fracture’s stability and healing progress.
  • Elevation and Ice:
    • Keeping the wrist elevated above heart level helps reduce swelling. Applying ice packs for 15-20 minutes at multiple intervals during the day can help manage pain and swelling.
  • Pain Management:
    • Over-the-counter pain medications, such as panadol or non-steroidal anti-inflammatory drugs (NSAIDs) like Nurofen, can be used to relieve pain and reduce inflammation.
  • Activity Modification
    • During healing, patients should avoid activities that strain or stress the wrist. Gentle finger movement is often encouraged to maintain circulation.
  • Follow-Up Care:
    • Regular follow-up appointments are required to monitor healing through clinical evaluation and periodic X-rays to ensure proper alignment and healing of the fracture. Access Ortho offers follow-up care in the clinic with our orthopaedic team. 

Surgical Interventions for Complex Colles Fractures

  • Open Reduction and Internal Fixation (ORIF):
    • Surgical intervention may be needed to realign the bones if the fracture is severely displaced or unstable. An ORIF involves making an incision to directly access the fracture, realigning the bone fragments, and securing them with plates, screws, or pins.
  • External Fixation:
    • In cases where soft tissue integrity is compromised or if there is significant swelling, an external fixation device may be used. This involves attaching a frame outside the body to stabilise the fracture.
  • Bone Grafting:
    • If there is a significant loss of bone due to comminution or previous injury, bone grafting may be considered during surgery to promote healing and stability.
  • Post-Operative Care:
    • After surgery, patients may need to wear a splint or cast for several weeks. To monitor healing, regular follow-ups with imaging studies will be necessary.

Pain Management Strategies for Colles Fracture Patients

  • Medications:
    • Prescription medications may be necessary for managing more severe pain, including stronger NSAIDs or opioids for short-term relief.
    • Adjunctive medications, such as muscle relaxants, may be prescribed to relieve muscle spasms.
  • Physical Therapy:
    • Once healing progresses, physical therapy can help manage pain through modalities like ultrasound, electrical stimulation, or manual therapy techniques.
  • Education:
    • Educating patients on the expected pain levels during recovery and strategies for managing discomfort at home can help alleviate anxiety.

Rehabilitation and Physiotherapy for Colles Fractures

Some patients do not require physiotherapy following a Colles Fracture. However, if stiffness or swelling are of concern, the following may be recommended: 

  • Early Mobilisation:
    • After initial healing (typically around 4-6 weeks after the injury), gentle range-of-motion exercises may be initiated to prevent stiffness. 
  • Strengthening Exercises:
    • Once range of motion is restored, progressive strengthening exercises focusing on wrist flexors, extensors, and grip strength are introduced. This may include resistance bands or light weights.
  • Functional Training:
    • Patients may engage in functional training exercises to practice activities of daily living, ensuring they regain full function and confidence in their wrist.
  • Education on Activity Modification:
    • Patients should be educated on gradually returning to sports or activities, with recommendations for protective gear as necessary to prevent re-injury.
  • Long-term Monitoring:
    • Follow-up appointments to assess recovery and adjust rehabilitation programs as needed to ensure optimal outcomes. Patients should also be monitored for any signs of complications, such as reduced mobility or persistent pain.

These approaches help ensure comprehensive care for patients with Colles fractures, facilitating optimal healing and recovery. Access Ortho is a leading fracture clinic in Brisbane and Ipswich and provides comprehensive orthopaedic care for fractures, sprains and strains. 

Prevention of Colles Fracture

Strategies to Reduce the Risk of Colles Fractures

Reducing the risk of Colles fractures, particularly in vulnerable populations such as older adults, involves a multifaceted approach:

  • Osteoporosis Management: Regular bone density screenings and proactive management of osteoporosis through medications, nutritional support (adequate calcium and vitamin D), and lifestyle modifications (like weight-bearing exercises) are crucial for strengthening bones and preventing fractures. It is important to discuss this with your GP.
  • Falls Prevention: Implementing home safety modifications, such as removing tripping hazards and improving lighting, can significantly reduce fall risks. Engaging in balance and strength training exercises (e.g., Tai Chi or yoga) enhances stability, while wearing appropriate footwear can help prevent slips.
  • Education and Awareness: Education about the risks of falls and the importance of preventive strategies empowers them to take action. Encouraging regular check-ups and discussions with healthcare providers about fracture risk can lead to tailored prevention plans.

By implementing these strategies, individuals can effectively lower their risk of experiencing Colles fractures and maintain their overall bone health.

Outlook and Prognosis for Colles Fracture

Typical Recovery Time for a Colles Fracture

The recovery time for a Colles fracture generally ranges from 6 to 12 weeks. This will depend on the severity of the fracture, the patient’s age, overall health, and adherence to treatment protocols.

  • Initial Healing: Most patients will have their cast or splint removed after about 4 to 6 weeks. During this time, the fracture begins to heal, and the focus is on immobilisation.
  • Rehabilitation: Following the removal of the cast, patients typically enter a rehabilitation phase that may last an additional 4 to 6 weeks. This phase focuses on regaining range of motion, strength, and function in the wrist.

Long-Term Prognosis and Potential Complications

  • Prognosis: Most individuals can expect a good long-term prognosis, with many returning to normal activities without significant long-term impairment. However, full recovery can vary based on individual factors, including age and pre-existing conditions.
  • Potential Complications:
    • Stiffness: Limited wrist mobility can occur if proper rehabilitation is not followed.
    • Malunion or Nonunion: Poor fracture healing can lead to improper alignment (malunion) or failure to heal (nonunion), which may require further treatment.
    • Post-Traumatic Arthritis: Patients may develop arthritis in the wrist joint over time, particularly if they have suffered significant injury to surrounding structures.
    • Nerve or Vascular Injury: Though rare, nerve or blood vessel damage may occur during the injury or treatment.

When to Expect a Return to Normal Activities

  • Initial Activities: Patients are often encouraged to resume light daily activities as tolerated once the cast is removed, typically around 6 weeks post-injury. However, they should avoid any high-impact or weight-bearing activities until cleared by their healthcare provider.
  • Return to Sports/Strenuous Activities: Most individuals can expect to return to sports or more strenuous activities within 3 to 6 months
  • Gradual Return: To avoid re-injury and 
  • ensure optimal recovery, it’s important to follow a gradual return-to-activity plan guided by a healthcare professional.

Overall, recovery from a Colles fracture requires careful monitoring and adherence to treatment protocols to achieve the best possible outcomes. Access Ortho offers specialist care for fractures and sprains. You can receive Urgent Care for all acute injuries, led by orthopaedic surgeons.
