方法:吾人使用雙光子骨質密度分析儀來測量50位男性脊髓損傷病人右側股骨頸的骨質密度並決定他們的骨折危險度。這些病人分別依據以下兩種條件分成兩類:(A)根據脊髓損傷的種類分為全癱及半癱;(B)根據脊髓損傷時間的長短分成短期(一年內)及長期(一年以上)。
結果:顯示39位病人(78%)有右側股骨頸骨折的危險。吾人比較全癱及半癱,短期及長期脊髓損傷病人有骨折危險的機率,發現全癱病人有較高的機率(93%),但與脊髓損傷時間的長短無關。
結論:我們的結論是股骨頸骨折將是脊髓損傷病人一個常見的併發症。而股骨頸骨折的機率與脊髓受傷的種類相關,但與受傷時間的長短無關。

Methods: Bone mineral density (BMD) of right femoral necks (RFN) in 50 young male spinal cord injury (SCI) patients (ages: ≦40 years) was measured by a dual photon absorptiometry (DPA) and the fracture risk was determined. The patients were separated into two groups according to the following two criteria, respectively: (A) the types of SCI was separated as quadriplegics and paraplegics, and (B) the periods after SCI attack was recorded as short (SCI≦1 year) or long (SCI>1 years).
Results: The results showed 30 cases (78%) had fracture risks in RFN. We compared the incidences of fracture risks between quadriplegics and paraplegics SCI and between short and long periods after SCI attack. The higher incidence of fracture risks in quadriplegia SCI patients was found (93%), but no significant differences for the incidence of fracture risks existed between the patients with shorter and longer periods after SCI.
Conclusions: We conclude that femoral neck fractures should be a common complication of SCI. The incidence with fracture risks of femoral necks are influenced by types of SCI lesions, not by SCI periods.
