Splinting and Casting




Abstract


This chapter provides a review of casting and splinting in children and adolescents.




Keywords

casting, fracture treatment, splinting

 





What is the purpose of casting and splinting?


To decrease pain, for mechanical stabilization, to prevent soft tissue contractures, to decrease further injury. Splints should be noncircumferential, somewhat loose, and applied in a position of function.





What materials are needed for splinting?





  • Gauze roll or elastic ACE bandage ( Fig. 46.1A )

  • Cotton stocking material (stockinette)



  • Soft cotton roll (Webril) ( Fig. 46.1B )



  • Fiberglass roll (Ortho glass) or plaster roll



  • Measuring tape/scissors/water






What are the layers of a splint, from inner to outer layer?





  • Stockinette (optional)



  • Soft cotton bandage/undersplint material (e.g., Webril padding), especially at bony prominences ( Fig. 46.2 )

  • Plaster or fiberglass placed to maintain position of immobilization



  • Outer layer of ACE bandage






What are the disadvantages of splinting?





  • Motion at the injury site



  • Patient noncompliance (taking off the splint)






What are the complications of casting an orthopedic injury in the acute phase?





  • Compartment syndrome



  • Pressure sores



  • Thermal injury



  • Joint stiffness



  • Skin infection and dermatitis






Is sedation required for splinting or casting?


Closed reduction for displaced fractures should always be done under sedation.





What are the indications for surgical management of clavicular fractures?


Open fracture, >100% displacement; complicated comminuted fractures; neurovascular/airway compromise.





What is a dreaded complication of forearm fractures?


Compartment syndrome. Significant ecchymosis is a risk factor for compartment syndrome in forearm fractures.





What are the contraindications for long arm posterior splint placement?


Complex and unstable distal forearm fractures





What is the proper splint to immobilize the wrist for fracture/sprain?


Volar ( Fig. 46.3 ) or dorsal splint with the following:

Volar Wrist Splint.

From Cromer DA: Splinting and casting. In: Rynders SD, Hart JA (eds): Orthopedics for Physician Assistants . Philadelphia, 2013, Saunders, p 373.


LENGTH = proximal fingers to proximal forearm


WIDTH = as wide or slightly wider than the surface of the forearm





What are the different methods of casting/splinting of the upper extremities?


See Table 46.1 .



Table 46.1

Upper Extremity Splinting and Casting













































Proximal or middle phalanx: stable and nondisplaced Buddy taping
Distal phalangeal fracture Aluminum U-shaped splint
Carpal bone fractures (excluding scaphoid and trapezium) Volar/dorsal splint
Scaphoid (nondisplaced) Thumb spica
First metacarpal and thumb fracture (nondisplaced) Thumb spica
Second or third metacarpal or corresponding proximal/middle phalangeal shaft fracture (nondisplaced/nonrotated) Radial gutter
Third or fourth metacarpal or corresponding proximal/middle phalangeal shaft fracture (nondisplaced/nonrotated) Ulnar gutter
Acute distal radial/ulnar fractures Sugar tong, long arm posterior splint
Proximal humeral/humeral shaft fractures Simple sling or coaptation splint for severely displaced fractures
Distal humeral, proximal (supracondylar Type I Gartland)/middle forearm, and nonbuckle wrist fractures Long arm posterior cast
Supracondylar (Type II, III Gartland) Surgical reduction with pin fixation
Lateral condylar fracture Surgical fixation
Medial condylar fracture (nondisplaced <3–5 mm) Long arm posterior splint
Clavicle (middle 1/3, distal 1/3, medial 1/3) Figure-of-eight splint or simple sling (need clavicle-specific x-rays)





Is there a difference in treating younger versus older children’s femur fractures?


Yes. There is a trend to treat younger children nonoperatively with suspension traction and spica casting. The trend in older children is to treat the femur fracture with sliding hip screw fixation/plate fixation.





Which lower extremity problems need splinting?





  • Ankle sprain



  • Distal tibia/fibula fracture



  • Metatarsal fracture






What is the proper splint to immobilize the above problems in question 13?


Sugar tong ( Fig. 46.4A )/Posterior ( Fig. 46.4B ) splint with the following:

A, Sugar tong ankle splint. B, Posterior ankle splint.

From Cromer DA: Splinting and casting.In: Rynders SD, Hart JA (eds): Orthopedics for Physician Assistants . Philadelphia, 2013 Saunders, pp 379–381.


LENGTH = fibular head to base of toes or fibular head around heel to below the medial knee


WIDTH = half the circumference of the lower leg





Is it appropriate to manage an open toe fracture with splinting only?


No. Open toe fractures, in which the germinal matrix of the proximal nail bed is trapped in the fracture site:




  • Need external repair and antibiotics



  • If severe, may need Open Reduction Internal Fixation surgery with K-wire repair and intravenous antibiotics






What are the different methods of casting/splinting the lower extremities?


See Table 46.2 .



Table 46.2

Lower Extremity Splinting and Casting
























Hip fracture Hip spica cast
Femur fracture Spica cast
Tibular/fibular fracture Long leg splint or long leg cast
Ankle fracture (nondisplaced) Short leg posterior splint or short leg cast
Fifth metatarsal fracture (Jones fracture) Bulky Jones dressing and postoperative shoe or non–weight-bearing short leg cast
Spiral fracture, fifth metatarsal neck (dancer’s fracture) Short leg cast
Toe fracture (nondisplaced) Buddy taping




Key Points




  • 1.

    Splinting is a potential treatment for nondisplaced, closed fractures or sprains.


  • 2.

    Contraindications to splinting include open fractures, fractures involving the joint, severe fractures (displaced, angulated, or overlapping fractures), Salter-Harris V fractures, severe plastic fractures (greenstick, bowing), or evidence of compartment syndrome.


  • 3.

    Splints should be placed with extremities in their normal position of function.
