Cervical Laminoplasty with Polypropylene Mesh: Our Experience

Cervical laminoplasty was made to reduce the complications of the simple laminectomy. The main indication is degenerative cervical myelopathy with posterior compression to two or more levels. To simplify this procedure with more effectiveness, we conceived a cervical laminoplastica with polypropylene mesh, generally used in abdominoplasty, to provide more resistance during mechanisms of flexion-extension. MATERIALS AND METHODS: We analyzed 35 patients (27 males, 8 females) with degenerative cervical myelopathy who underwent surgical tretament at our institution between 2010 and 2015. RESULTS AND DISCUSSION: The main duration of surgery was about 90 minutes without intra or post-operative complications. Clinical and radiological follow-up was done at 1, 3 and 6 months, with cervical dynamic Rx and cervical RM at 1one year. There were no complications and 70% of the patients experienced a stable clinical improvement, while in 30% of patients stabilization of clinical deficits. The duration of the superior clinical to one year and the age > of 70 years the more meaningful negative prognostic indicators have appeared. CONCLUSIONS: A clinical history more than one year and the age elder than 70 years appear the main negative prognostic factors. The advantage of the laminoplasty is a smaller anatomical damage of the posterior elements without cervical instability, and use of polypropylene mesh provides more resistance during flexion-extension.
