[Efficacy of double-door laminoplasty combined with hydroxyapatite artificial bone grafting for cervical spinal stenotic myelopathy].

OBJECTIVE

To evaluate the effects of double-door laminoplasty and hydroxyapatite artificial bone grafting in the treatment of cervical spinal stenotic myelopathy.

METHODS

Twelve cases of cervical spinal stenotic myelopathy underwent expansive double-door laminoplasty of the cervical spine and hydroxyapatite artificial bone grafting. The clinical outcome of the patients and the operative procedures were assessed.

RESULTS

The 5-year follow-up showed significantly alleviated clinical symptoms and improved physical signs in all the patients except for 1 patient who responded poorly to the surgery.

CONCLUSIONS

Expansive double-door laminoplasty of the cervical spine in combination with hydroxyapatite artificial bone grafting is safe and effective for treating cervical spinal stenotic myelopathy. Hydroxyapatite artificial bone possesses good biological compatibility and osteoconduction, and is applicable in the laminoplasty procedures as an ideal bone graft material.
