Analysis of Cervical Spine Alignment Change after Modified Kurokawa Cervical Laminoplasty in the Patients with Cervical Myelopathy and Straight Cervical Spine

Figure 2

Surgical technique. (a) The supraspinous ligament preservation and the connecting points between the posterior muscular ligament complex with the bony elements. (A) The preservation of muscular attachment during the laminoplasty. Just near the medial side of the articular capsular. During the final stage of suturing, we need to connect (B) with (D), (C) with (E) and (F) contralaterally. (b) Posterior view of reconnection between the muscular ligament and bonny elements. (c) Adjustment of Mayfield three-point head fixator from the mild straight curve in the beginning of surgery to the lordotic curve in the beginning of suturing. The original distance between C2 and C7 is distance (A); after suturing, the distance changed to (B) (A > B). (C) The continuous suturing of posterior ligament and fascia to form a strong tension bend which could maintain the lordotic curve.
