Posterior Scoliosis Surgery
Understanding Scoliosis and When Surgery is Needed
Scoliosis is a condition where the spine curves abnormally to one side, forming an “S” or “C” shape. While mild cases often have no symptoms, severe scoliosis can cause postural imbalances, uneven shoulders or hips, back pain, and even breathing difficulties in extreme cases.
Most scoliosis cases, especially in children and adolescents, are classified as idiopathic scoliosis, meaning the cause is unknown. Diagnosis involves a physical examination and imaging tests such as X-rays, CT scans, or MRI to assess the degree of spinal curvature. If the curve is mild, bracing may be recommended to prevent progression. However, when the curvature exceeds 45 degrees, posterior scoliosis surgery may be necessary to correct the alignment and stabilize the spine.
At Texas Spine Group, we specialize in advanced surgical techniques, including posterior spinal fusion, to help patients achieve a straighter, more stable spine.
What is Posterior Scoliosis Surgery?
The posterior approach is the most common and traditional method used to treat scoliosis, particularly in adolescents with idiopathic scoliosis. In this procedure, the surgeon accesses the spine from the back (posterior side) to correct the abnormal curvature and prevent further progression.
This approach involves posterior fusion, a procedure that fuses affected vertebrae using bone grafts, along with screws, hooks, or rods to maintain alignment while the spine heals.
Procedure for Posterior Spinal Fusion
Step 1: Anesthesia and Positioning
- The patient is placed under general anesthesia.
- Positioned face-down on the operating table with arms and legs carefully padded for protection.
Step 2: Incision and Exposure
- Several small incisions are made, deA long incision is made down the middle of the back, depending on the location and severity of the spinal curve.pending on the curvature’s location and severity.
- The spinal muscles are carefully stripped from the vertebrae to expose the affected area.
Step 3: Placement of Spinal Instrumentation
- Screws, hooks, wires, or other fixation devices are inserted at the necessary vertebral levels.
- A specially contoured rod is attached to these connection points to straighten and stabilize the spine.
- Adjustments are made to achieve optimal spinal alignment.
Step 4: Spinal Fusion
- Bone graft material or substitutes are placed between the affected vertebrae to promote fusion.
- Over time, the grafted bone fuses with the vertebrae, creating a single, solid bone structure.
Step 5: Closure and Drain Placement
- Once all implants are securely placed, a final tightening is performed.
- The incision is closed, and a drain may be inserted to prevent fluid buildup.
The entire procedure typically takes several hours, depending on the complexity of the spinal curvature.
Recovery After Posterior Scoliosis Surgery
- Initial Recovery – Patients remain in the hospital for several days for monitoring and pain management.
- Spinal Healing – The spine appears significantly straighter after surgery, but full fusion takes time.
- Fusion Process – It takes a minimum of 3 months for initial bone fusion, with complete fusion occurring over 1 to 2 years.
- Physical Therapy – Rehabilitation helps restore mobility, strengthen muscles, and ensure proper posture.
Risks and Potential Complications
While posterior fusion is a highly effective procedure, it is a major surgery with potential risks, including:
- Excessive blood loss
- Infection at the surgical site
- Failure of spinal fusion (pseudoarthrosis)
- Nerve damage, which may lead to weakness or paralysis (rare)
- Cerebrospinal fluid leakage
- Instrumentation issues such as broken rods or dislodged screws
