Any medical complication can occur after hip resculpting, although infection, deep vein thrombosis and pulmonary embolus are rare.
Complications specific to the operation include:
Persistance of symptoms
Patients may still have hip pain even after adequate resculpting
Progression to osteoarthritis
Whilst resculpting is performed to hopefully reduce the risk of osteoarthritis, there are no guarantees and OA may still develop (usually years) after resculpting
Avascular necrosis of the femoral head
The reported risk of this is very low (< 1%) but if it develops it can have catastrophic implications for the hip; subsequent hip replacement may be necessary.
Non-union of the trochanteric osteotomy
This is where the cut part of the femur fails to unite to the rest of the bone after surgery. Re-operation to re-fix the segment, possibly with the use of a bone graft may be required
Occasionally scarring around the hip causes stiffness. This usually responds well to physiotherapy.
Occasionally the nerve that supplies the skin on the outer part of the thigh (called the lateral cutaneous nerve of the thigh) can be stretched during surgery and a numb patch subsequently develops. This usually resolves after 6 months but in rare cases can be permanent.
