A morphologic study of manubrium sterni using 3-dimensional computed tomography (3D-CT). ⋯ The size of male manubrium is significantly larger than that of female manubrium. Manubrium bone is far more sufficient for most adult anterior cervical fusion surgeries. Safe area for procurement of graft is defined as the upper two-thirds of manubrium, and the optimal site to access medullar cavity is suggested at bare area. However, because considerable variability of manubrium size exists, preoperative evaluation of manubrium is suggested to avoid pitfalls, especially when manubrium graft is intended in a female patient.

A retrospective review. ⋯ Contrary to traditional thinking, properly selected NIDDM was not a significant risk factor for perioperative complications or additional surgeries in adult patients with spinal deformities.
-
An in vitro investigation of the biomechanics of the intact and destabilized sheep cervical spine. ⋯ The sheep cervical spine is extremely flexible, as seen by the large range of motion and neutral zone. The large neutral zone may account for the coupled motion between axial rotation and lateral bending. The facets and capsular ligaments provide significant stability, especially in axial rotation, flexion, and extension.
-
In vivo biomechanical study in quadruped model. ⋯ Compressive stresses were dynamic at both control and stapled levels, which indicated that the disc was not immobilized by the implant. These pilot results suggested that mean disc compression was increased within the first postoperative week. Stresses ranged up to levels measured in humans.
-
A clinical retrospective study. ⋯ Surgical management for subaxial cervical spinal metastasis was found to be effective in terms of neurological recovery and pain control. Furthermore, surgical treatment plus adjuvant therapy was found to achieve sufficient local control during postoperative follow-up.
