Background: Degenerative cervical myelopathy is a spinal disorder resulting in progressive spinal cord compression and consequent neurological deficits that can be assessed and tracked using the modified Japanese Orthopedic Association (mJOA) questionnaire. However, it is difficult to predict which patients will recover neurological function after surgery, making it difficult for clinicians to set reliable postoperative patient expectations. Methods: Sixty-eight operative myelopathy patients (50 male, 14 female) consented to complete the mJOA questionnaire both preoperatively and 6-months postoperatively. Fifteen of these patients had mild, twenty-three had moderate, and thirty had severe preoperative disease. Results: We found that in mild myelopathy, sensation and strength recover in similar proportions. In moderate myelopathy, a greater proportion of patients recover in each domain except for sensation. Recovery in severe myelopathy was comparable to moderate disease, but showed more dramatic recovery in sensation and sphincter function. Conclusions: This study shows that the severity of myelopathic disease influences the pattern of postoperative recovery. Though limited in sample size, the recovery patterns identified above are an important first step in recognizing myelopathy as a disease that patients experience heterogeneously both pre- and post-operatively. Our results will aid clinicians in goals-of-surgery discussions and assist with managing postoperative patient expectations.
