Some hips present with complex deformities. Examples are shown below. These hips often have had previous surgery resulting in severe stiffness or anatomical deformities. Others have significant congenital abnormalities like hip dislocation.
Careful pre-operative planning is done often using the OPS software analysis and an operative plan developed with attention to implant positioning and implant types. Surgery is performed via the posterior approach. Occasionally extra bone graft is required to the pelvis/acetabulum or even femoral bone shortening (in high congenital hip dislocation).
Recovery may include protected weight bearing on crutches for 6 weeks. These hips will usually take longer to recover but the end result is what counts.
These are examples of complex hip replacements:
