Osteotomy, iliac, acetabular or innominate bone
CPT4 code
Name of the Procedure:
Osteotomy, Iliac, Acetabular or Innominate Bone (Common name: Pelvic Osteotomy)
Summary
A pelvic osteotomy is a surgical procedure to correct deformities in the hip joint by cutting and repositioning the bones of the pelvis. This helps to improve joint function and alleviate pain.
Purpose
This procedure addresses hip dysplasia, arthritis, and various congenital or developmental deformities. The goal is to create a more stable and functional hip joint, relieve pain, and potentially delay the need for a total hip replacement.
Indications
- Hip dysplasia
- Pain due to arthritis in the hip
- Developmental deformities of the hip joint
- Untreated congenital hip dislocations
- Adults or children with hip problems impacting mobility
Preparation
- Fasting for at least 8 hours before surgery
- Adjustments to current medications as advised by the physician
- Pre-surgical imaging tests such as X-rays, MRI, or CT scans to plan the surgery
- Blood tests and a physical exam to ensure readiness for surgery
Procedure Description
- The patient is placed under general anesthesia.
- An incision is made over the iliac, acetabular, or innominate bone.
- The surgeon cuts and repositions the bone to correct the deformity.
- Internal fixation devices like screws or plates are used to secure the repositioned bones.
- The incision is closed with sutures or surgical staples.
Tools and Technology:
- Oscillating saws
- Surgical drills
- Plates and screws for internal fixation
Duration
The procedure typically lasts between 2 to 4 hours.
Setting
The surgery is performed in a hospital operating room.
Personnel
- Orthopedic surgeon
- Surgical nurses
- Anesthesiologist
- Surgical technician
Risks and Complications
- Infection
- Blood clots
- Nerve damage
- Bleeding
- Failure of the bones to heal properly (nonunion)
- Possible need for future surgeries
Benefits
- Improved hip stability and function
- Pain relief
- Enhanced mobility
- Delay or prevention of total hip replacement surgery
Recovery
- Hospital stay of 3 to 5 days
- Use of crutches or a walker for 4 to 6 weeks
- Physical therapy for strength and mobility
- Follow-up appointments to monitor healing
- Full recovery can take up to 6 months
Alternatives
- Physical therapy and exercise
- Pain management with medication
- Total hip replacement in severe cases
- Less invasive surgical options like arthroscopy
Patient Experience
Patients may experience pain and discomfort managed by medication. Swelling and bruises around the surgical site are common. Gradual improvement in hip function and pain relief is expected over several months. Physical therapy is crucial for a successful recovery.
