Periacetabular osteotomy involves a series of cuts in the pelvic bone to free up the acetabulum, or socket of the hip joint. Once free, it can be manoeuvred into a more suitable position and held in place with screws. The osteotomy cuts will then heal to secure the acetabular fragment into its new position. This operation is most frequently performed for patients who have developmental problems of the hip leading to an incorrectly orientated acetabulum, such as developmental dysplasia (DDH).
HOSPITAL STAY AND REHABILITATION
Periacetabular osteotomy usually requires a hospital stay of around 3-5 days. You will need crutches for the first 6 weeks to avoid putting too much weight through the leg whilst the bone heals. Depending only your job and your commute, a further period of 2-6 weeks off work may be needed.
Your physiotherapy programme is vital to a successful outcome and will commence shortly after your discharge from hospital. It will begin with simple strengthening and stretching exercises, followed by a gradual increase in activity starting with non-impact exercises such as cycling and swimming. A full recovery and return to activities may take up to a year, and the usual plan would also include removal of the screws at around 9-12 months.
The potential risks and complications of periacetabular osteotomy include infection, bleeding and major blood vessel injury, nerve damage leading to temporary or permanent pain, weakness or numbness in the leg, a fracture into the joint at surgery or a stress fracture elsewhere in the pelvis post-operatively, non-union or mal-union of the fragment and blood clots (DVT/PE).
A cell saver is routinely used so any blood loss at surgery can be returned to you either during or after your procedure, to minimise the need for a blood transfusion.
Other specific risks and complications pertinent to you and your particular surgery will be discussed with you in detail prior to the procedure, and if you have any particular concerns or feel you have not fully understood, Jonathan would be happy to clarify things at a clinic appointment prior to your operation date.
When you come for surgery, you will be asked to sign a consent form detailing the procedure and demonstrating that you accept and understand the risks and potential complications of your operation.
