ABSTRACT:
An orthopedic table for applying controlled flexion and traction to a patient's body includes a table divided at its mid-region into upper and lower platforms. A patient lying on the table is harnessed at the opposite ends of the table, and pelvic straps on the lower platform secure the patient's pelvic region to the lower platform. The platforms pivot simultaneously to periodically lower the central region of the table and separate the inner edges of the platforms. The support provided by the pelvic straps enables the lowered platforms to periodically force the patient's lower back into flexion in the separation space between the platforms. The remote end of the lower platform is adjustable in elevation to control the pull on the patient's hamstrings which, in turn, controls the amount of flexion exerted on the patient's lower back. The patient's head or arms can be selectively harnessed at the head of the upper platform to place the patient's upper body in traction during lowering of the platforms. A harness for the patient's head is secured to a vertically adjustable support for controlling the amount of flexion applied to a patient's neck during lowering of the table. A harness for the patient's arms also has a vertically adjustable support to control the amount of flexion applied to the patient's shoulders. The amount of traction applied by either harness is adjustable, and the head harness is rotatable to either side during lowering of the platforms to increase rotational freedom of the patient's neck.
