INTRODUCTION: Ossification of the posterior longitudinal ligament (OPLL) is a hyperostotic spinal condition resulting from progressive endochondral ossification of the posterior longitudinal ligament, leading to spinal canal narrowing and spinal cord compression. Primarily seen in East Asian countries, OPLL has been increasingly recognized in North American cohorts. This study aims to evaluate the demographic characteristics and outcomes of patients undergoing surgery for OPLL in a North American cohort.
METHODS: This was a single-center retrospective cohort study of patients with OPLL undergoing surgery between July 2011 and November 2024. Data collected included demographic information, body mass index (BMI), comorbidities, surgical approach, OPLL classification, and K-line measurement. Estimated blood loss (EBL), intra/post-operative complications, length of stay, and disposition status were also recorded. Descriptive statistics and multivariable analyses were conducted with a p value < 0.05 considered to be statistically significant.
RESULTS: In total, 81 patients underwent surgery for OPLL (mean age of 60 years; 50.6 % male). Most of the patients were Black (43 patients, 53.1 %).The mean BMI was 33.1 kg/m2. Forty-four patients (54.3 %) had diabetes. Most of the surgeries were elective (88.9 %). The classification of OPLL for the patients were: 31.7 % segmental, 20 % continuous, and 40 % mixed. 73.3 % of the patients had a positive K-line. Surgically, the posterior approach (41 patients, 50.6 %) was more common. A posterior approach was more likely to be utilized for patients with a positive K-line measurement (p = 0.029). Obesity was associated with increased EBL (p = 0.032). Five patients experienced intraoperative complications. The mean length of stay was 6.5 days, and average follow-up was 20.4 months. Three patients (3.7 %) passed post-operatively, and none underwent reoperation.
CONCLUSION: This study highlights the demographic and clinical characteristics of OPLL in a diverse North American cohort. Surgical management, predominantly via anterior or posterior approaches, was associated with low complication rates and no reoperations during follow-up.
