Surgery at the cervicothoracic junction (CTJ) poses risks. Laminectomy or multilevel ventral corpectomies at the CTJ increase failure rates, especially in patients with prior surgery or tobacco use.

Area of Science:

  • Neurosurgery
  • Spinal Surgery
  • Orthopedics

Background:

  • The cervicothoracic junction (CTJ) is a critical transitional zone between the cervical and thoracic spine.
  • Its unique biomechanical properties make it susceptible to instability, particularly after surgical intervention.

Purpose of the Study:

  • To identify factors associated with treatment failure in surgeries involving the cervicothoracic junction (CTJ).
  • To provide evidence-based recommendations for improving surgical outcomes at the CTJ.

Main Methods:

  • Retrospective review of 593 CTJ surgeries performed between 1998 and 2003.
  • Analysis of variables including construct failure, deformity, and instability as indicators of treatment failure.
  • Statistical analysis using the Fisher exact test to determine associations.

Main Results:

  • Treatment failure occurred in 14 patients (2.36%).
  • Laminectomy and multilevel ventral corpectomies with fusion across the CTJ were significantly associated with treatment failure.
  • Prior cervical surgery, tobacco use, and deformity correction surgery were also linked to higher failure rates.

Conclusions:

  • The cervicothoracic junction (CTJ) is vulnerable to surgical complications.
  • Laminectomy at the CTJ requires supplemental instrumentation and fusion.
  • Multilevel ventral corpectomies at the CTJ necessitate dorsal instrumentation.
  • Consider supplemental instrumentation for patients with prior cervical surgery, tobacco use, or undergoing deformity correction.
