Summary

Spinal pseudarthroses, or non-unions, are categorized by cause and presentation. Surgical options for axis (C2) non-union and spondylolysis in young patients are discussed.

Area of Science:

  • Orthopedics
  • Spinal Surgery
  • Radiology

Background:

  • Spinal pseudarthroses represent a significant clinical challenge.
  • Classification systems are crucial for understanding spinal non-unions.
  • Various etiologies contribute to the development of spinal pseudarthroses.

Purpose of the Study:

  • To classify spinal pseudarthroses based on etiology and clinical presentation.
  • To describe the radiological and clinical features of different spinal non-union types.
  • To highlight operative treatment considerations for specific spinal pseudarthroses, including axis (C2) non-union and spondylolysis.

Main Methods:

  • Review of spinal pseudarthrosis classifications.
  • Description of clinical and radiological findings.
  • Analysis of operative treatment strategies for specific spinal non-unions.

Main Results:

  • Spinal pseudarthroses are categorized into congenital, acquired non-traumatic, posttraumatic, and postoperative types.
  • Clinical and radiological appearances vary significantly among different pseudarthrosis classifications.
  • Specific recommendations are provided for operative management of axis (C2) pseudarthrosis and spondylolysis.

Conclusions:

  • Accurate classification of spinal pseudarthroses is essential for effective management.
  • Operative treatment for axis (C2) pseudarthrosis may involve posterior fusion (Gallie-Brooks technique).
  • Direct repair is a potential option for spondylolysis without significant slippage in younger individuals.
