Some clients are inactive and physically immobile as a result of an overall debilitating condition. For others, mobility impairment results from trauma or its treatment. Such is the case for clients with orthoses, which are orthopedic devices that support or align a body part and prevent or correct deformities.

Examples include inflatable splints, traction splints, immobilizers, molded splints, and cervical collars. Inflatable and traction splints are intended for short-term use: they usually are applied just after the injury and are removed shortly after more thorough assessment of the injury.

17 17 Casts A cast is a rigid mold placed around an injured body part after it has been restored to correct anatomic alignment. A cast is a rigid mold placed around an injured body part after it has been restored to correct anatomic alignment. The purpose of the cast is to immobilize the injured structure. Casts usually are applied to fractured (broken) bones. They are formed using either wetted rolls of plaster of Paris or premoistened rolls of fiberglass (Table 25-1).

19 19 Types of Casts There are basically three types of casts: cylinder, body, and spica. There are basically three types of casts: cylinder, body, and spica.

20 20 1. Cylinder Cast encircles an arm or leg and leaves the toes or fingers exposed. The cast extends from the joints above and below the affected bone. This prevents movement, thereby maintaining correct alignment during healing. encircles an arm or leg and leaves the toes or fingers exposed.

When the cast is removed, the unexercised muscle is usually smaller and weaker. The joints may have a limited range of motion. The skin usually appears pale and waxy and may contain scales or patches of dead skin. The skin is washed as usual with soapy warm water, Applying lotion to the skin adds moisture and tends to prevent the rough skin edges from catching on clothing.

38 38 Traction Traction is a pulling effect exerted on a part of the skeletal system. It is a treatment measure for musculoskeletal trauma and disorders. Traction is used to accomplish the following: Traction is a pulling effect exerted on a part of the skeletal system. It is a treatment measure for musculoskeletal trauma and disorders. Traction is used to accomplish the following: Reduce muscle spasms Reduce muscle spasms Realign bones Realign bones Relieve pain Relieve pain Prevent deformities Prevent deformities

39 39 The pull of the traction generally is offset by the counterpull from the client's own body weight. Except for traction exerted with the hands, application of traction involves the use of weights connected to the client through a system of ropes, pulleys, slings, and other equipment.

40 40 Types of Traction

41 41 1. Manual Traction Manual traction means pulling on the body using a person's hands and muscular strength (Fig. 25-18). It most often is used briefly to realign broken bone. It also is used to replace a dislocated bone into its original position within a joint. Manual traction means pulling on the body using a person's hands and muscular strength (Fig. 25-18).

43 43 2. Skin Traction Skin traction means a pulling effect on the skeletal system by applying devices, such as a pelvic belt and a cervical halter, to the skin (Fig. 25-19). Other names for commonly applied forms of skin traction are Buck's traction and Russell's traction (Fig. 25-20).

Skeletal traction is applied continuously for an extended period.

48 48 Traction Care Regardless of the type of traction used, its effectiveness depends on the application of certain principles during the client's care (Box 25-1). See Nursing Guidelines 25-3.

49 49 Box 25-1 Principles for Maintaining Effective Traction Traction must produce a pulling effect on the body. Countertraction (counterpull) must be maintained. The pull of traction and the counterpull must be in exactly opposite directions. Splints and slings must be suspended without interference. Ropes must move freely through each pulley. The prescribed amount of weight must be applied. The weights must hang free
