To the best of the authors' knowledge, no studies in the literature have compared the clinical outcome of the three most common implants used to treat basicervical fractures of the femoral neck in young adults, CCS, DHS, and PFN. The present study attempts to fill the void in the literature and reach a conclusion regarding the usefulness of these implants in these fractures.
This was a prospective interventional study including 90 patients with basicervical fracture of the neck of femur treated randomly with cancellous cannulated lag screws or dynamic hip screw, with a derotation screw or short PFN.
Mean time for fracture union was 14.4, 13.9, and 13.5 weeks and union rate was 93.2%, 100%, and 100% in groups 1, 2, and 3, respectively. The mean Harris Hip Score at the final follow up was similar among all the groups, 79.4, 82.2, and 81.9 in CCS, DHS, and PFN groups, respectively. The highest proportion of good to excellent results was noted in the DHS group, 83.3%, whereas it was 73.6% and 80% in the CCS and PFN groups, respectively.
Multiple cancellous screws do not provide a sufficiently stable construct during fracture healing. PFN, although associated with lesser implant failures than CCS, have a higher incidence of technical errors. DHS provides sufficient stability in well-reduced basicervical fractures in young adults; it is associated with highest fracture union rates and best functional outcome out of the three implants at final follow-up.
据作者所知,文献中尚无研究比较用于治疗年轻成人股骨颈基底部骨折的三种最常用植入物(CCS、DHS和PFN)的临床疗效。本研究试图填补文献中的空白,并就这些植入物在这些骨折中的效用得出结论。
这是一项前瞻性干预性研究,纳入90例股骨颈基底部骨折患者,随机采用松质骨空心拉力螺钉或动力髋螺钉、带旋转螺钉或短PFN进行治疗。
第1、2和3组骨折愈合的平均时间分别为14.4周、13.9周和13.5周,愈合率分别为93.2%、100%和100%。所有组在末次随访时的平均Harris髋关节评分相似,CCS组、DHS组和PFN组分别为79.4、82.2和81.9。DHS组优良结果的比例最高,为83.3%,而CCS组和PFN组分别为73.6%和80%。
多根松质骨螺钉在骨折愈合过程中不能提供足够稳定的结构。PFN虽然与CCS相比植入物失败率较低,但技术失误的发生率较高。DHS为年轻成人复位良好的股骨颈基底部骨折提供了足够的稳定性;在末次随访时,它与三种植入物中最高的骨折愈合率和最佳的功能结果相关。
