Abstract: An adjustable back brace having a posterior wound clearance. The back brace includes a pair of spaced apart support members configured to extend circumstantially about a patient's waist. Each support member has a posterior portion and an anterior portion. The anterior portions overlap one another and are adjustably secured to one another with hook and loop fasteners when the back brace is worn by the patient. A pair of inelastic straps secure and tighten the back brace about the patient's waist. Each strap is anchored approximately adjacent the patient's spine to one of the posterior portions. The straps extend toward one another across the wound clearance to rings attached to the opposite posterior portion. The straps pass through the rings to reverse direction and extend back across the wound clearance, around the patient's sides, and to the patient's anterior.
