Wrist fractures are among the most common bone injuries, often occurring when a person falls onto an outstretched hand (known as a FOOSH injury). While the injury can be painful and temporarily debilitating, modern orthopedic care offers effective treatments that lead to excellent functional recovery. Understanding the types of fractures and the comprehensive management steps is key to navigating the healing process.
Understanding the Common Types of Wrist Fractures
The wrist is made up of eight small carpal bones and the two forearm bones (the radius and ulna). Most wrist fractures involve the larger forearm bone, the radius, at its distal (far) end near the wrist joint.
1. Distal Radius Fractures
This is the most frequent type of wrist fracture. The treatment approach heavily depends on how the bone fragments are displaced:
- Colles’ Fracture: The most common pattern, where the broken fragment of the radius tilts upward (dorsally) toward the back of the hand. It often results from falling onto an extended hand.
- Smith’s Fracture: Less common, this is sometimes called a reverse Colles’ fracture. The broken fragment tilts downward (volarly) toward the palm side. It typically results from falling onto a flexed wrist.
- Barton’s Fracture: An intra-articular fracture (extending into the joint surface) that involves dislocation of the wrist joint.
2. Scaphoid Fractures
The scaphoid is a small, boat-shaped carpal bone located near the base of the thumb. Fractures to this bone are concerning because of its poor blood supply. This can put it at a high risk of delayed healing or non-union (failure to heal) if not treated appropriately, often requiring a longer period of immobilization or surgical stabilization.
Diagnosis and Initial Treatment
Immediate medical attention is necessary if you suspect a wrist fracture. Symptoms typically include severe pain, swelling, tenderness, and potentially a visible deformity.
Diagnosis
- Physical Examination: The physician assesses the injury, checking for deformity, tenderness, and nerve/blood vessel integrity.
- X-rays: Standard X-rays are the primary diagnostic tool, showing the bone alignment, fracture location, and severity.
- CT Scan or MRI: These may be used for complex injuries, especially those that extend into the joint (intra-articular) or to better evaluate scaphoid fractures.
Initial Care (Immediate)
Initial treatment focuses on stabilizing the injury, controlling pain, and reducing swelling. This usually involves applying a splint and elevating the hand above the heart level.
Comprehensive Fracture Management Options
Treatment is determined by the fracture type, stability, displacement, patient age, and activity level.
1. Nonsurgical Management (Closed Reduction and Immobilization)
If the fracture is non-displaced (the bone fragments are still correctly aligned) or can be easily aligned through manipulation (known as a closed reduction), conservative treatment is used.
- Closed Reduction: The orthopedic specialist carefully manipulates the broken bone fragments back into their anatomical position, usually under local anesthesia (hematoma block) or sedation.
- Casting: After reduction, a cast or splint is applied to immobilize the wrist for typically four to six weeks to allow the bone to heal. Serial X-rays are often taken in the first two weeks to ensure the fragments maintain alignment.
2. Surgical Management (Open Reduction)
Surgery is required for unstable fractures, fractures that cannot be adequately reduced non-surgically, or severely displaced intra-articular fractures. The goal of surgery is stable fixation to allow for earlier motion and rehabilitation.
- Open Reduction Internal Fixation (ORIF): The surgeon makes an incision to directly visualize the fracture, realign the fragments, and secure them with internal fixation devices such as plates and screws. Volar plating (fixing the fracture from the palm side) is a common technique for distal radius fractures.
- External Fixation: A metal frame is placed outside the body, with pins that pass through the skin into the bone fragments on either side of the fracture. This frame holds the bones in alignment and is often used for severely comminuted (broken into many pieces) or open fractures where soft tissue damage is extensive.
- Percutaneous Pinning: Small metal pins (K-wires) are inserted through the skin and across the fracture site to hold the fragments in place.
This is often used for stable, extra-articular fractures or in conjunction with external fixation.
Recovery and Rehabilitation: The Path to Function
Regardless of whether treatment is surgical or nonsurgical, the rehabilitation phase is critical for restoring full strength and range of motion (ROM) to the wrist.
Phase 1: Immobilization and Early Care
- Pain and Swelling Control: Continue elevation and use prescribed or over-the-counter anti-inflammatory medications.
- Movement of Unaffected Joints: While in the cast or splint, it is essential to regularly move the fingers, thumb, and elbow to prevent stiffness in these adjacent joints.
Phase 2: Post-Immobilization Therapy
Once the cast or splint is removed (typically 4–8 weeks later), the wrist will likely be stiff and weak. Physical or Occupational Therapy (Hand Therapy) is vital at this stage.
| Exercise Category | Purpose | Example Movements |
| Range of Motion (ROM) | Restores joint flexibility. | Wrist flexion (bending forward) and extension (bending back). Radial (thumb side) and ulnar (little finger side) deviation. Forearm rotation (pronation and supination). |
| Strengthening | Rebuilds muscle strength. | Squeezing a stress ball or therapy putty. Wrist curls using light weights or resistance bands. Towel wringing (requires flexibility and strength). |
Full recovery and return to vigorous activities can take several months, but consistent adherence to a tailored rehabilitation program offers the best chance for an optimal outcome.
Conclusion
Wrist fractures are common but highly treatable injuries. Management involves careful diagnosis, appropriate immobilization through casting or surgical fixation, and a dedicated rehabilitation protocol. By working closely with orthopedic specialists and hand therapists, patients can effectively manage their recovery, minimize long-term stiffness, and regain the full function and strength necessary for daily life.
Frequently Asked Questions (FAQs)
1. How long does it take for a wrist fracture to heal?
For most distal radius fractures, the bone is sufficiently healed after 4 to 8 weeks of immobilization. However, full recovery of strength and range of motion, often requiring physical therapy, can take 3 to 6 months. Scaphoid fractures may take significantly longer due to poor blood supply.
2. What is a closed reduction, and does it require anesthesia?
A closed reduction is a non-surgical procedure where the doctor manually manipulates the displaced bone fragments back into the correct alignment without making an incision. It is typically performed under local anesthesia (like a hematoma block) or conscious sedation to minimize pain.
3. Will I always need surgery for a broken wrist?
No. Surgery is only required for unstable fractures, open fractures, or fractures where the bone fragments cannot be adequately aligned using closed reduction. Many stable, non-displaced wrist fractures can heal successfully with casting and immobilization alone.
4. What are the signs that my cast might be too tight?
A cast that is too tight can impair circulation or nerve function. Warning signs include persistent or increasing pain, severe swelling in the fingers, numbness or tingling in the hand/fingers, or a change in finger color (pale, white, or blue). If these symptoms occur, you should seek immediate medical attention.
5. When can I start rehabilitation exercises after a wrist fracture?
You can start gentle range-of-motion exercises for your uninjured joints (fingers, thumb, elbow) immediately while the cast is on. However, you should only start movement exercises and strengthening for the injured wrist once your physician or hand therapist confirms the fracture has stabilized, usually after the cast is removed.
