PCF is a procedure performed to address nerve root compression in the cervical spine.
Moreover, patients with more than 10 years of follow-up had a reoperation rate of 24.3%.
#Neck fusion problems years later series#
While the reoperation rate for the overall cohort in this series was 9.9%, patients with follow-up periods longer than 2 years had a reoperation rate of 18.3%. Following the subgroup that experienced initial symptom improvement, 16.1% of these patients experienced radiculopathy recurrence an average of 7.3 years after the initial operation. At last follow-up, the overall rate of improvement in radiculopathy was 85%, with the majority of patients (91.4%) experiencing resolution as early as 1 month after index surgery. The rate of same-level reoperation (6.6%, 10 patients) was significantly higher (p = 0.05) when compared with adjacent-segment (1.3%, 2 patients) or distant-segment (1.9%, 3 patients) reoperation. A smaller number of patients had reoperation that included a repeat PCF (6.7%) or laminectomy with posterior cervical fusion (13.3%). The majority of patients who underwent a reoperation had an anterior cervical discectomy and fusion (80%). Patients who presented with preoperative neck pain in addition to radiculopathy had a higher risk for reoperation and a shorter time to reoperation. The average time until reoperation was 2.4 years, and the average last follow-up examination was 4.15 years after the first surgery.
Kaplan-Meier analyses were conducted to assess risk of reoperation and recurrence of radiculopathy over time.Īfter index PCF in 151 patients, the overall reoperation rate was 9.9% (15 patients). The main outcome variables were reoperation rate, time to reoperation, and short- and long-term radiculopathy improvement rates. The authors retrospectively reviewed demographic, surgical, and clinical data from 151 patients who underwent unilateral PCF at their institution with an average follow-up of 4.15 years. The authors conducted a study to investigate the rate and timing of reoperation due to symptom recurrence after unilateral posterior cervical foraminotomy (PCF).
