Abstract: A modular orthopedic bracing system is provided. The orthopedic bracing system includes a walking boot configured to cover at least the plantar aspect of the user's foot, a support detachably connectable to the walking boot and configured to suspend the weight of the user and an ankle-foot orthosis (“AFO”) detachably connectable to the walking boot. Also disclosed is a method for supporting an injured lower extremity, which includes the steps of attaching a first support member to the patient's leg, providing a second support member for an area at or beneath the foot and posterior portion of the lower leg, providing a first upward force on the patient's leg with the first support member, providing a second upward force on the foot with the second support member. By adjusting the amounts of the first upward force and the second upward force, the foot and lower leg, supported by the AFO, may be fully suspended, partially suspended or rest completely on the foot bed of the walking boot.
