Chapter 31 Orthotics
31.1 Casting (Includes serial casting; casting for burns)
OVERVIEW.
A cast is a rigid casing applied around a body part.1 Serial casting involves recasting over time and is used to treat contractures by affecting muscle length, soft tissue extensibility, and possibly affecting muscle spindle excitability. The applied load on soft tissue is low and duration is long (i.e., not a quick stretch). Casting of burns offers plastic deformation of connective tissue, biomechanical realignment of joint structures, and protection of exposed tendons, fragile skin, or wounds.

31.2 Orthotics
OVERVIEW.
An orthosis is an external device that is worn on a body part to support, correct, or prevent deformities or to align body structures for improved function.1 Webster’s dictionary2 defines it as a straightening treatment for the maladjusted. The term splint varies in meaning and may refer to either a hand orthosis3 or a temporary external device.1 Some examples of orthoses include body jackets, hand splints, ankle foot orthoses, knee cages, elastic stockings, and corrective shoes.
SUMMARY.
Concerns for spinal and lower and upper limb (including hand splints) orthotics are varied and depend in large part on the patient’s clinical presentation and involved body region. Skin monitoring is recommended in most, if not all, orthotic applications. In general, orthotic concerns include skin ulceration in insensate or poorly vascularized skin, skin allergies from splint materials, contracture promotion (e.g., using UE slings in persons with UMN lesions), worsened spasticity (e.g., using dynamic splints in persons with UMN lesions), and orthotics that either fail to adequately stabilize critical body segment (e.g., high cervical fracture) or fail to control a crucial movement component (e.g., deleterious rotational forces). In addition to pressure ulcer complications, pressure-related neuropathies4,5 and compartmental syndromes6 have been reported with orthotic use.
