Surgical correction of fixed kyphosis

Area of Science:

• Orthopedic Surgery
• Spinal Deformity Correction
• Spine Biomechanics

Background:

• Surgical correction of fixed kyphosis carries a high risk of paraplegia.
• Limited data exists on the comparative effectiveness of different surgical approaches for rigid kyphosis.

Purpose of the Study:

• To evaluate the outcomes of surgical correction for rigid fixed kyphosis.
• To compare the efficacy of various surgical approaches and techniques.

Main Methods:

• Retrospective review of 23 patients with rigid fixed kyphosis.
• Surgical procedures included anterior, posterior, and combined approaches with or without total vertebrectomy.
• Patients with active tuberculosis, fractures, or degenerative lumbar changes were excluded.

Main Results:

• Average kyphotic angle improved from 71.8 to 39.2 degrees, achieving a 57% correction rate.
• Combined approaches, especially total vertebrectomy, showed the highest correction rates for acute angular kyphosis (>60 degrees).
• Clinical outcomes were excellent in 17 patients, good in 5, and poor in 1.

Conclusions:

• Combined surgical approaches, particularly total vertebrectomy, are effective and safe for correcting severe acute angular kyphosis.
• The choice of surgical technique should be tailored to the specific type and severity of kyphosis.
• Further research is warranted to optimize surgical strategies for spinal deformities.
