Technique Thumb Cast
|Application: The materials should be pre-prepared
to enable rapid application of the bandage. All the necessary materials should
be placed within reach to avoid hold-ups in the procedure.
The patient should be in a position which is comfortable to him/her and the person applying the bandage. This may vary depending on the extent of the injury, the diagnosis, the treatment method and the patient's condition.
Materials required: 1 x 5 cm Delta Cast Conformable polyester support bandage with hydrogel-coated casting gloves, toweling tubular bandage, fleece padding, tape or adhesive bandage, bandage scissors, felt-tip pen.
The small number of layers means that the cast remains semi-flexible and can be adjusted depending on the individual state of the swelling (looser or tighter). To do this, the tape strapping or adhesive bandage is removed and the cast altered for a perfect fit. Re-application is carried out as described above.
Short thumb cast: Through cutting at the distal thumb end the thumb can get its full function back. This leads to a focused fixation of the base thumb joint.
Thumb cast with wrist inclusion: Here the proximal part of the cast stays on. This has the effect of stabilizing the base thumb joint and the wrist.
Scaphoid cast: After application of a Terry Cloth Stockinet the cast gets applied proximal up to the elbow in the sense of focused rigidity casting. (See also: Radius cast). In most cases it is not necessary to split the cast in the thumb region. The scaphoid cast is a combination of the thumb- and radius casts.
