| アブストラクト | Introduction: Laminoplasty is a well-established technique used to manage cervical myelopathy (CM). Nevertheless, the degree to which United States surgeons have adopted laminoplasty from Japan to treat CM is less clear. The purpose of this study was to compare operative management strategies for CM in the United States (US) with Japan. Methods: This study used a retrospective cohort of 16,084 patients from the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database and 389,872 patients from the Japanese Diagnosis Procedure Combination (DPC) database from 2007 to 2015. Patients with the following diagnoses were collected: spondylosis with myelopathy (ICD-19; 721.1, ICD-10; M47.12) and disk herniation with myelopathy (ICD-9; 722.71, ICD-10; M50.00). The proportion of surgeries between Japan and the US was compared using a linear regression model controlling for year. Results: US surgeons utilized anterior procedures in 70% of cases compared to 9% in Japan (p<.001). In contrast, Japan had significantly more laminoplasties than the US (43% vs. 4%, respectively, p<.001). The percentage of laminoplasty in Japan (43%) relative to the percentage in the US (4%) was significantly different (p<.001). Accounting for increases in the number of total surgeries per year seen in the ACS-NSQIP and DPC databases, no specific surgery demonstrated a significant increase or decrease over the 8 years. Conclusions: Japanese surgeons employ laminoplasty to treat CM approximately ten times more frequently than US surgeons who prefer anterior procedures. |
