The Ultimate Guide To Dorsal Block Splints For Optimal Joint Immobilization

Dorsal block splints are immobilizing devices designed to protect and support injured fingers or thumbs. These splints, typically made of aluminum or thermoplastic materials, are customized to fit the specific anatomy of the injured digit and provide rigid support to limit movement and promote healing. Their application involves positioning the splint dorsally (on the back side of the hand) and securing it with straps or tape. Dorsal block splints are commonly used for a variety of hand injuries, including fractures, sprains, and dislocations, and their use requires careful monitoring by nurses to ensure proper fit, circulation, and patient education.

Understanding Dorsal Block Splints: Definition and Purpose

What are Dorsal Block Splints?

Dorsal block splints are medical devices custom-designed to immobilize injured fingers or thumbs. These splints resemble small, cozy blocks that gently encase the affected digit, providing support and protection. They are typically made of lightweight materials like plastic or aluminum, which offer comfort and ease of use.

Role in Immobilization

These splints play a crucial role in healing by immobilizing the injured digit. Immobilization prevents further damage to the ligaments, tendons, and bones, allowing the natural healing process to take its course. By restricting movement, dorsal block splints help reduce pain, improve stability, and facilitate a quicker recovery.

Related Concepts: Types of Finger Splints and Materials

Understanding the diverse range of finger splints and materials employed in the construction of dorsal block splints is crucial for selecting the most suitable option for specific hand injuries.

Types of Finger Splints

• Kite Splints: These splints resemble kites and are designed to immobilize a single finger or thumb. They consist of a dorsal (back of the hand) and palmar (palm of the hand) section connected by straps, providing excellent support and stability.

• Buddy Splints: As the name suggests, these splints “buddy up” two adjacent fingers by immobilizing them together. This approach is particularly effective in stabilizing fractures or dislocations involving multiple fingers.

• Ulnar Gutter Splints: These splints are U-shaped and designed to support the ulnar (pinky finger) side of the hand. They are commonly used to treat mallet finger (a rupture of the extensor tendon on the tip of the finger) or other injuries affecting the ulnar aspect of the hand.

Materials for Dorsal Block Splints

The choice of material for dorsal block splints depends on factors such as durability, comfort, and breathability.

• Plastic: Plastic splints are lightweight and durable, making them ideal for long-term use. They are also waterproof, allowing for easy cleaning.

• Aluminum: Aluminum splints are lightweight and can be molded to conform to the shape of the hand. They provide excellent support and can be adjusted as needed.

• Fabric: Fabric splints are comfortable and breathable, making them suitable for patients with sensitive skin. They are also adjustable, allowing for a customized fit.

Combination Materials: Some dorsal block splints combine different materials to optimize both comfort and support. For instance, a splint may have a plastic base with a fabric lining for enhanced breathability.

Choosing the appropriate type of finger splint and material for dorsal block splints is vital for effective immobilization and injury management. Understanding the available options enables healthcare professionals to tailor treatment to the specific needs of each patient.

Dorsal Block Splints: A Comprehensive Guide to Application

Dorsal block splints offer a versatile solution for immobilizing fingers and thumbs, aiding in the healing process of various hand injuries and conditions. Understanding the proper application technique is crucial for ensuring optimal patient outcomes. Here’s a step-by-step guide:

Positioning and Fit

Before applying a dorsal block splint, it’s essential to position the patient’s hand and splint appropriately. Place the dorsal surface of the hand on a flat surface with the thumb abducted. Align the splint with the longitudinal axis of the finger or thumb. Ensure the splint extends proximally beyond the metacarpophalangeal joint and distally beyond the interphalangeal joint.

Securing Techniques

Velcro straps or elastic bandages are commonly used to secure dorsal block splints. To begin, wrap the base of the splint snugly around the wrist without overtightening. Next, place the middle strap over the distal palm and tighten firmly. Finally, secure the top strap above the metacarpophalangeal joint.

Monitoring and Care

Once the splint is applied, it’s crucial to monitor the fit and circulation regularly. Assess the skin beneath the splint and remove it periodically to check for redness or swelling. Instruct the patient to report any discomfort or changes in sensation immediately.

Applying dorsal block splints effectively requires attention to proper positioning, secure fastening techniques, and ongoing monitoring. By following these guidelines, healthcare professionals can ensure the best possible outcomes for patients with hand injuries or conditions.

Indications and Contraindications for Dorsal Block Splints

Indications:

Dorsal block splints are primarily used to immobilize fingers or thumbs that have sustained injuries or are affected by certain conditions. These include:

• Joint sprains and dislocations: Splints help keep the injured joint in proper alignment while it heals.
• Bone fractures: Splints support and protect broken bones to facilitate healing.
• Tendon injuries: Splints can prevent further damage to tendons by immobilizing the affected area.
• Rheumatoid arthritis: Splints can reduce pain and swelling by limiting movement in affected joints.
• Carpal tunnel syndrome: Splints can hold the wrist in a neutral position to relieve pressure on the median nerve.

Contraindications:

While dorsal block splints are generally safe and effective, there are certain situations where they may not be appropriate:

• Open wounds: Splints should not be applied directly over open wounds as they can trap bacteria and hinder healing.
• Circulation problems: Individuals with poor circulation should consult a healthcare professional before using a splint as it can restrict blood flow.
• Skin allergies: Some materials used to make splints may cause allergic reactions in sensitive individuals.
• Severe pain: If an injury is causing severe pain, a splint may not be suitable and immediate medical attention should be sought.

Nursing Implications of Dorsal Block Splints: Ensuring Optimal Patient Outcomes

Assessing Fit and Monitoring Circulation

Nurses play a pivotal role in ensuring the proper fit and circulation of dorsal block splints. Upon application, nurses meticulously assess the alignment and positioning of the splint to prevent pressure points or discomfort. They monitor circulation in the affected finger or thumb by observing skin color, warmth, and capillary refill time. Regular palpation helps detect any potential pressure or tightness issues.

Education and Patient Empowerment

Nurses serve as educators, empowering patients to actively participate in their recovery process. They provide clear and concise instructions on how to remove, clean, and reapply the splint. They also emphasize the importance of regular hand exercises to maintain mobility and prevent stiffness. Patients are taught to recognize signs of complications, such as pain, swelling, or numbness, and are instructed to seek medical attention promptly.

Promoting Patient Comfort and Safety

Nurses consistently monitor patients for comfort and safety. They ensure the splint is not causing discomfort or skin irritation. They remove the splint periodically to allow for skin inspection and air circulation. If pressure sores or other complications arise, nurses intervene immediately to mitigate risks and provide appropriate care.

Precautions and Potential Complications of Dorsal Block Splints

Precautions During Application:

When applying a dorsal block splint, it’s imperative to ensure a proper fit to prevent discomfort and potential complications. The splint should be snug but not so tight that it impairs circulation or causes nerve damage. Carefully adjust the straps or Velcro closures to achieve a secure fit without overtightening.

Potential Complications:

Despite proper application, certain complications may arise with prolonged use of dorsal block splints. One common concern is pressure sores. Prolonged pressure on the skin can lead to tissue damage, especially in areas where there is less padding, such as the knuckles or fingertips. To prevent this, regularly check the skin beneath the splint for any redness or irritation. If any signs of pressure sores appear, adjust or remove the splint and notify a healthcare professional.

Another potential complication is impaired sensation. The splint can temporarily block certain nerve impulses, leading to numbness or tingling in the fingers or thumbs. Usually, sensation returns when the splint is removed. However, prolonged compression can cause more permanent nerve damage. To minimize this risk, check circulation regularly by pressing on the nail beds of the splinted digits. If color changes or pulses are absent, seek medical attention immediately.

By following proper application protocols and closely monitoring patients with dorsal block splints, you can help prevent or mitigate potential complications. If any concerns arise, promptly seek professional advice to ensure the patient’s well-being and optimal recovery.
