title: Surgical outcome of cervical expansive laminoplasty in patients with diabetes mellitus.
abstract: METHODS
  The results from cervical laminoplasty in 18 patients with diabetes mellitus were compared with results from the same procedure in 34 nondiabetic patients matched for age, gender, and disease.
  
  
  OBJECTIVE
  To analyze the effects of diabetes mellitus on the surgical outcome after cervical laminoplasty.
  
  
  BACKGROUND
  There have been no reports on the results of cervical laminoplasty patients with diabetes.
  
  
  METHODS
  A retrospective analysis of 18 patients with diabetes mellitus who underwent cervical laminoplasty and 34 nondiabetic patients who underwent the same surgical procedure was undertaken. The postoperative score, intra- and postoperative findings, complications, and radiologic factors were compared between the two groups. In the group with diabetes, the correlation between the recovery rate of the Japanese Orthopedic Association score and the factors indicating the severity of diabetes was assessed.
  
  
  RESULTS
  There was no statistical difference between the total Japanese Orthopedic Association scores of the two groups. However, the group with diabetes mellitus showed a poor recovery of sensory function of the lower extremities. Three patients in the group with diabetes had superficial wound complication after surgery. In contrast, none of the patients in the control group had a wound problem. Furthermore, a negative correlation was observed between the recovery rate and the preoperative HbA1 level in the group with diabetes.
  
  
  CONCLUSIONS
  Although patients with diabetes mellitus who had cervical myelopathy experienced benefits from cervical laminoplasty similar to those of nondiabetic patients, the patients with diabetes were more likely to have wound complication. Furthermore, the negative correlation between the recovery rate and the preoperative HbA1 value might suggest that long-term diabetes control of more than 2 to 3 months before surgery at least is recommended for a favorable surgical outcome.
