Ponte osteotomies in thoracic deformities.

Area of Science:

• Orthopedic Surgery
• Spinal Deformities

Background:

• Thoracic hyperkyphosis is a sagittal spinal deformity causing pain and neurological deficits.
• Sagittal thoracic malalignment presents with varied causes and requires tailored surgical correction.
• Preoperative planning, including classification and pelvic parameter analysis, is crucial for successful surgical outcomes.

Purpose of the Study:

• To discuss the role of Ponte osteotomies in correcting thoracic hyperkyphosis.
• To highlight the importance of preoperative planning in sagittal spinal deformity surgery.

Main Methods:

• Ponte osteotomies are posterior column osteotomies indicated for long, non-angular hyperkyphotic thoracic deformities.
• This technique is also beneficial for idiopathic scoliosis, rigid deformities, and proximal junctional kyphosis.
• Correction requires a mobile anterior column and can achieve up to 10° correction per level.

Main Results:

• Ponte osteotomies facilitate significant correction of thoracic hyperkyphosis.
• The technique is versatile, applicable to various rigid spinal deformities.
• Successful correction is dependent on anterior column mobility.

Conclusions:

• Adequate preoperative planning is essential for surgical correction of sagittal thoracic malalignment.
• Ponte osteotomies are an effective surgical option for specific types of thoracic hyperkyphosis and related deformities.
• Restoring sagittal alignment is key to improving patient outcomes.
