To evaluate the clinical effect of cannulated screw on treatment of femoral neck fracture (FNF).
Forty-two FNF patients were treated by using cannulated screw from January 2001 to December 2005. There were 22 males and 20 females with an average age of 41 years (19-59 years). Fracture was caused by traffic accident in 21 cases, by falling from height in 14 cases and by bruise in 7 cases. All cases were fresh fracture. According to Garden criterion for typing, 15 cases were classified as type I , 16 cases as type In and 11 cases as type IV. It was 7 hours to 15 days from injury to operation.
The patients were followed up for 1-6 years with an average of 2.5 years. The average fracture union time was 6.5 months. Three patients had ischemic necrosis of femoral head, and loosening and breakage of screw and rob was observed in 1 case. According to Brumback criterion for hip joint function, the result was excellent in 18 cases, good in 20 cases and bad in 4 cases, and the excellent and good rate was 90.4%.
Cannulated screw fixation is a good method to treat FNF in young adults. It can improve the rate of fracture union and reduce the rate of avascular necrosis of femoral head.
评估空心螺钉治疗股骨颈骨折（FNF）的临床效果。
2001年1月至2005年12月，采用空心螺钉治疗42例股骨颈骨折患者。其中男性22例，女性20例，平均年龄41岁（19 - 59岁）。骨折原因：交通事故致伤21例，高处坠落致伤14例，摔伤7例。所有病例均为新鲜骨折。根据Garden分型标准，I型15例，II型16例，IV型11例。受伤至手术时间为7小时至15天。
患者随访1 - 6年，平均2.5年。骨折平均愈合时间为6.5个月。3例发生股骨头缺血性坏死，1例出现螺钉及棒松动、断裂。根据Brumback髋关节功能标准，优18例，良20例，差4例，优良率为90.4%。
空心螺钉内固定是治疗青壮年股骨颈骨折的一种良好方法。它能提高骨折愈合率，降低股骨头缺血性坏死率。
