jacket restraint, an orthopedic device used to help immobilize the trunk of a patient in traction and to discourage the patient from sitting up in bed. The jacket restraint is attached to both sides of the bedspring frame by means of buckled webbing straps that are sewn into the side seams of the restraint. The jacket restraint may be used with most kinds of traction but is not usually used with Dunlop skin traction, Dunlop skeletal traction, Bryant traction, halo-femoral traction, or halo-pelvic traction. A restraint of any kind should be used only when the risk of activity outweighs the benefits, and even then with extreme caution. Compare diaper restraint, sling restraint.
