Postlaminectomy kyphosis. Causes and surgical management

Area of Science:

• Spine surgery
• Orthopedic surgery
• Neurosurgery

Background:

• Postlaminectomy instability of the cervical spine is a potential complication following laminectomy.
• Instability can lead to significant morbidity and impact patient outcomes.

Purpose of the Study:

• To discuss the management options for postlaminectomy cervical spine instability.
• To compare anterior and posterior surgical approaches for managing this condition.

Main Methods:

• Review of existing literature on surgical management of postlaminectomy cervical spine instability.
• Discussion of the timing and technical considerations for anterior and posterior stabilization techniques.

Main Results:

• Posterior stabilization procedures are most effective when performed concurrently with the initial decompressive laminectomy.
• Performing posterior procedures during the initial surgery can prevent the development of kyphotic deformity.
• Anterior stabilization and arthrodesis may be technically simpler if a kyphotic deformity has already developed post-laminectomy.

Conclusions:

• The choice of surgical approach for postlaminectomy cervical spine instability depends on the presence or absence of kyphotic deformity.
• Prophylactic posterior stabilization during laminectomy is recommended to prevent kyphosis.
• Anterior approaches offer a viable alternative for managing established postlaminectomy kyphosis.
