The effect of early fusion on growth of the spine has been studied in rabbits. Free periosteal grafts from the tibia were transplanted either posteriorly between the spinous and articular processes or postero-laterally between the articular and transverse processes. Sound bony fusion was achieved in both the thoracic and the lumbar spine. Spinal fusion caused local narrowing and wedging of the intervertebral spaces, followed by retardation of growth and wedging of the vertebrae. A progressive structural scoliosis developed after unilateral postero-lateral fusion and a lordosis developed after posterior fusion.
已经在兔子身上研究了早期融合对脊柱生长的影响。取自胫骨的游离骨膜移植片被移植到棘突与关节突之间的后方，或关节突与横突之间的后外侧。在胸椎和腰椎均实现了稳固的骨融合。脊柱融合导致椎间隙局部变窄和楔形改变，随后椎体生长迟缓和楔形改变。单侧后外侧融合后出现进行性结构性脊柱侧凸，而后方融合后出现脊柱前凸。
