Abstract

|
Bacground: Failed neck surgery syndrome (FNSS) may be used to describe patients with intractable chronic neck and/or upper extremity pain despite one or more operations for cervical degenerative disease. Among this patient population, cervical spinal cord stimulation (SCS) has been largely unexplored.
Methods: We retrospectively reviewed our experience using cervical SCS in 8 patients (4 men, 4 women) with FNSS.
Results: Following a 3-day paddle trial of SCS, 6 patients (75%) experienced at least 50% relief and underwent permanent paddle lead and pulse generator implantation. At a mean follow-up time of 6.2 years, these patients reported a mean pain reduction of 55.2% on a 0-10 scale. All 6 claimed improved quality of life; 5 patients (83.3%) reported decreased pain medication requirements following SCS. However the SCS was only effective for a mean duration of 2.0 years. Only 1 patient continues to use SCS, but 4 of 6 patients (66.7%) were willing to undergo repeat cervical SCS.
Conclusions: Paddle lead cervical SCS has good therapeutic potential but technological improvements and investigations into mechanisms of reduced efficacy are warranted to improve its long-term durability among patients with FNSS.
