Introduction[edit | edit source]
Purpose[edit | edit source]
Splints have various purposes. Including:
- Support to Promote Healing
- Positioning or supporting during function
- Pain Relief 
- Substitute for Weak Muscles
- Prevention and Correction of Contracture & Deformity 
- Restoration or Maintenance of Range of Motion 
- Edema Control 
Different Types of Splints[edit | edit source]
Splints are classified based on the movement permissible as
- Serial Static
- Static Progressive
Regional Splints[edit | edit source]
1. Splints for Upper Extremity[edit | edit source]
|Region||Type of Splint|
|Ulnar Side of Hand||Ulnar Gutter Splint|
|Radial Side of Hand||Radial Gutter Splint|
|Thumb, First Metacarpal, and Carpal Bones||Thumb Spica Splint|
|Wrist / Hand||
|Elbow, proximal forearm, and skeletally immature wrist injuries||
2. Splints for Lower Extremity[edit | edit source]
|Region||Type of Splint|
|Lower Leg, Ankle and Foot||Short Leg Cast|
|Knee and Lower Leg||Posterior Knee Splint|
|Foot||Short Leg Cast with Toe Plate Extension|
Indications of Splinting[edit | edit source]
Splints are used to immobilize musculoskeletal and nerve injuries, support healing, and to prevent further damage. The indications for splinting are broad, but commonly include:
- Temporary stabilization of acute fractures, sprains, strains or nerve injuries before further evaluation or definitive operative management
- Immobilization of a suspected occult fracture (such as a scaphoid fracture)
- Severe soft tissue injuries requiring immobilization and protection from further injury
- Definitive management of specific stable fracture patterns
- Peripheral neuropathy requiring extremity protection
- Partial immobilization for minor soft tissue injuries
- Treatment of joint instability, including dislocation 
Contraindications of Splinting[edit | edit source]
No specific contraindications to splinting exist. However, certain injuries and patient-specific co-morbidities require special attention:
- Injuries that Violate the Skin or Open Wounds:
- Antibiotic administration should be considered for these patients depending on the severity of the lesion. These patients also require additional soft tissue care, which may necessitate tissue debridement and skin closure before splint application.
- Injuries that Result in Sensory or Neurological Deficits:
- The complications of splint placement such as compartment syndrome, pressure injuries, or malreduction may go unnoticed if the patient has a concurrent nerve injury. These patients should undergo evaluation by a surgeon before splint application as neurologic findings may be a sign of a surgical emergency.
- Injuries to the Vasculature:
- This requires special attention by vascular surgeons, as these may require urgent operative intervention. Furthermore, evaluation of the vasculature is essential both before and after splint application, as the reduction of some fractures may result in acute arterial injury or obstruction if trapped between the fracture fragments.
- Patients with Peripheral Vascular Disease or Peripheral Neuropathy:
- Special care should be taken when applying lower extremity splints in these patients since their baseline sensation may be altered. These patients have difficulty detecting pressure sores, skin irritation, and possible vascular compromise.
Side Effects of Splinting[edit | edit source]
- Excessive use of splints can lead to chronic pain, stiff joints or weak muscles 
- Skin irritation 
- Discomfort 
Advantages of Splinting[edit | edit source]
Splint use offers many advantages over casting.
- Splints are faster and easier to apply.
- They may be static (i.e., prevent motion) or dynamic (i.e., functional; assist with controlled motion).
- Splints are non-circumferential, allowing for natural swelling that occurs during the initial inflammatory phase of the injury.
- A splint may be removed more easily than a cast, allowing for regular inspection of the injury site.
Disadvantages of Splinting[edit | edit source]
Disadvantages of Splinting include;
- Poor Patient Compliance
- Excessive Motion at the Injury Site
- Limitations in their usage, as in unstable or potentially unstable fractures
Complications of Splinting[edit | edit source]
- Compartment Syndrome
- Heat Injury
- Pressure Sores and Skin Breakdown
- Joint Stiffness
- Altered Range of Motion
- Decreased Strength
- Altered Sensation
- Neurological injury
Considerations for Effective Splinting[edit | edit source]
- Creases provide for landmarks in splint fabrication
- Bony prominences may cause pressure
- Ensure three points of pressure
- Custom made splints to fit the contours of the body rather than ready-made splints
- Patient education for better compliance
