Previous work has shown that extensive areas of bone necrosis developed after Z-osteotomies of the femoral shaft. A study was made on 11 dogs to compare the effects of a transverse osteotomy followed by immediate lengthening, stabilisation by plates and bone grafting. The bone vitality was studied at 8 and 16 weeks by histological sections and angiography. Attention was focussed on the area of lengthening and the bone ends. The results showed the superiority of transverse osteotomy over Z-osteotomy. Bone necrosis diminished at the 16 th week. In the area of lengthening, the vascularity of the grafts was satisfactory. In contrast, the tendons of the Z-osteotomy showed constant necrosis.
先前的研究表明,股骨干Z形截骨术后会出现大面积骨坏死。对11只狗进行了一项研究,比较了横向截骨后立即延长、钢板固定和植骨的效果。通过组织学切片和血管造影术在第8周和第16周研究骨活力。重点关注延长区域和骨端。结果显示横向截骨术优于Z形截骨术。骨坏死在第16周时减少。在延长区域,移植骨的血管分布令人满意。相比之下,Z形截骨术的肌腱持续出现坏死。
