Applied anatomy of cervical unilateral open-door laminoplasty with reconstruction lamina (titanium miniplate) fixation
Objective To provide anatomic parameters for the cervical unilateral open-door laminoplasty with reconstruction lamina(titanium miniplate) fixation. Methods 50 sets of dry cervical vertebrae specimens were observed in this study. The width, height and thickness of lateral masses(LMW, LMH, LMT), the surface length from the external border of lateral masses to the plane of 5mm above the basilar part of spinal process(LSL), the height and thickness of the lateralis and median part of laminar(LH1, LH2, LT1,LT2), the height and width of the basilar part of spinal process(SPH1,SPW1) and the plane of 5 mm above the basilar part of spinal process(SPH2,SPW2) were measured and analyzed. Results LMW was about C3(9.89±0.97)mm, C7(12.09±0.93)mm. LMH C4(11.44±2.09)mm, C7(13.56±2.17)mm, which was linear correlated, increased gradually. LMT C3(9.03±1.46)mm and C7(6.66±0.78)mm, which decreased gradually. LSL C3(25.21±2.08)mm, C6(27.09±1.80)mm, C7 and C4 was similar. LH1 C3(11.54±1.66)mm, C7(16.83±1.77)mm and LH2 C3(10.91±1.58)mm, C7(14.86±1.48)mm, increased gradually. LT1 C5(4.44±0.81)mm, C7(5.28±0.76)mm and LT2 C4(3.00±0.86)mm, C7(4.92±0.96)mm. SPH1 C4(9.33±1.67)mm, C7(11.34±1.57)mm and SPH2 C4(7.10±1.76)mm, C7(9.82±1.46)mm, C3 and C5 was similar. SPW1 C5(8.59±1.81)mm, C7(11.13±1.76)mm and SPW2 C5(6.66±1.86)mm, C7(8.50±1.58)mm, which was the shortest in C5, the longest in C7. Conclusions Cervical unilateral open-door laminoplasty with reconstruction lamina (titanium miniplate) fixation is feasible anatomically. It can enlarge cervical vertebral canal and reconstruct the stability of lamina.
