We used the stainless steel cable grip system described by Dall and Miles in 1983 to fix trochanters in 40 hips after total arthroplasty with trochanteric osteotomy. The cable broke in 32.5% of the hips; the trochanter failed to unite in 37.5%. Significantly more cables broke when placed inside the femoral canal than when the cable was placed round the femoral shaft (58% as against 9.5%, difference p less than 0.01). The high incidence of breakage may have resulted from contact between the stainless steel cable and the titanium prosthesis, from the acute angulation, or because of the lower fatigue strength of stainless steel. Better results have been obtained using cables with a higher fatigue strength, passed outside the proximal femur.
我们采用了1983年由多尔(Dall)和迈尔斯(Miles)描述的不锈钢缆索固定系统,在40例转子截骨全关节置换术后的髋关节中固定转子。32.5%的髋关节中缆索断裂;37.5%的转子未能愈合。置于股骨髓腔内的缆索断裂比例显著高于置于股骨干周围的缆索(分别为58%和9.5%,差异p小于0.01)。缆索的高断裂发生率可能是由于不锈钢缆索与钛假体之间的接触、急性成角或不锈钢较低的疲劳强度所致。使用疲劳强度更高的缆索并置于股骨近端外侧,已取得了更好的效果。
