High reclining back, pommel cushion, and solid seat insert. Patients who have had a total hip replacement (THR) using a posterior surgical approach (the most common method) must be careful to not flex the affected hip beyond 90 degrees of flexion, adduct the hip, or internally rotate the hip. A wheelchair with a sling type seat should include a solid seat insert to prevent the sling seat from pushing the hip toward internal rotation, a pommel cushion to position the patient’s hips in abduction, and a high reclining back to allow the patient to sit with the hip positioned at less than 90 degrees of hip flexion.
