Abstract: A modular patient positioning system includes: a first pegboard having a first pegboard hole; a second pegboard rotatably coupled to the first pegboard and having a second pegboard hole, the first pegboard and second pegboard lying along a common plane in a first configuration and the first pegboard and second pegboard lying along different planes in a second configuration. A first body portion and a second body portion of a patient's body may be positioned and supported in different planes by having the first pegboard support the first body portion and the second pegboard support the second body portion; and a leg positioner including a mounting structure for mounting the leg positioner on the second pegboard and positioning a leg in a predetermined position relative to the second pegboard. The mounting structure of the leg positioner allows for adjusting axial rotation, abduction/adduction, elevation/depression, and/or flexion/extension of the leg.

Abstract: During orthopedic surgeries, body parts are moved in different ways to cause different anatomic features (e.g. muscles or the trochanters) to tighten or loosen, or become more or less prominent during the intended surgical incisions, which can result in easier surgical procedures. Body parts can be moved using a variety of different structures. The exemplary structures described herein can allow for: (1) a person's leg and foot to be rotated about the axis of the leg (i.e., femur/tibia axis); (2) a person's leg can be pivoted generally about the hip/femoral head/acetabulum to vary the angle between the axis of the leg and a median sagittal plane; (3) a person's leg can be moved in a direction parallel to the leg axis; and/or a person's leg can be pivoted in a generally vertical plane, about the femoral head/acetabulum while the axis of the leg and the median sagittal plane remaining substantially parallel.

Abstract: Multiple embodiments of a modular patient positioning system for use during surgical procedures are disclosed. In one exemplary embodiment the system comprises two hinged-together pegboards that can be used to support different portions of a patient's body in different planes. Pegs can be further used to retain portions of the patient's body in desired surgical positions. Additionally, a positioning member, such as a pad or cushion may be positioned over several pegs.
