摘要

本文報告25名複雜、不穩定的股、脛骨骨折採用Groosse-Kempf互鎖式髓內釘(lnIerlocking Intramedullary Nail)的初步結果。因其生物力學設計上與傳統的髓內釘極其不同(1)，重量完全由釘子承受。因此早期復健強調輕微部分載重，必須等到骨痂長出，拿掉一端的螺釘(bolt)，才可以完全載重，否則釘子容易斷掉或彎曲(8)。在本次追蹤中，病人大多沒有活動化(Dynamination)但結果良好的，股骨病例中佔88.9%，脛骨病例中占81.3%，沒有釘子彎曲或斷掉的情況。

Twenty five comminuted unstable fractures of femur or tibia were treated with the Grosse-Kempf interlocking nail. The biomechanical properties of interlicking nail are quiet different from the intramedullary nail The osteosynthesis material assumes the full load in static interlicking nail, though in Kuntscher nail, the osseous cylinder itself can vear the weight. Partial weight-bearing is permitted in early stage. Full weight-bearing is allowed after the dynamization while the bridging callus are formed. Too early weight-bearing will produce bending or fracture of the nail. Excellent or good result were obtained in 88.9% of the patients of femoral fractures, and 81.3% of the patients of tibia fractures. There was no bending or fracture of nail.
