BACKGROUND Combined ipsilateral femoral neck and shaft fractures are an uncommon type of fractures. A number of different implant options are available for the management of this injury. Two-device procedures were suggested because of the higher rate of malunion by single-device treatment. However, surgical treatment using a cephalomedullary nail is still an alternative option that provides better mechanical advantage and minimal invasion. This study details the technique of treating these pattern fractures with proximal femoral nail anti-rotation II (PFNA-II) to achieve an acceptable reduction in both fracture sites. METHODS Ten cases of ipsilateral femoral neck and shaft fractures under reduction by PFNA II were included and reviewed. A saw-bone model was also utilized to perform the detailed technique of reduction and fixation of PFNA II. RESULTS Under the special technique by using the PFNA II, all ten cases achieved optimal reduction and alignment of both fracture sites in intra-operative fluoroscopy. There was no intra-operative complication noted. After 6 months of follow-up, radiography revealed proper alignment and well union of the fractures. CONCLUSIONS Fixation of ipsilateral femoral neck and shaft fractures with a single construct provides advantages of good biomechanical function, minimal invasion, reduced blood loss, and less operation time when comparing to two-device fixation. Thus, if acceptable reduction could be achieved, fixation by one PFNA II was a good alternative choice for this injury pattern.

同侧股骨颈和干轴骨折伴近端股骨钉抗旋转II(PFNA II)固定:技术说明和病例系列。

背景技术同侧股骨颈和干联合骨折是一种罕见的骨折类型。有许多不同的植入物可供选择以管理这种损伤。建议使用两装置程序,因为单装置治疗的畸形率更高。但是,使用头颅髓内钉的外科手术治疗仍然是一种替代选择,可提供更好的机械优势和最小的侵袭。这项研究详细介绍了用股骨近端抗旋转钉II(PFNA-II)治疗这些型式骨折的技术,以实现两个骨折部位的可接受的复位。方法回顾性分析10例经PFNA II复位的同侧股骨颈干骨折。锯骨模型还被用来执行PFNA II复位和固定的详细技术。结果在特殊技术下,通过使用PFNA II,所有10例患者在术中X线透视中均实现了最佳的骨折复位和对准。没有发现术中并发症。随访6个月后,X线摄片显示骨折正确对准并愈合良好。结论与两装置固定相比,用单一结构固定同侧股骨颈和干轴骨折具有良好的生物力学功能,最小的浸润,减少的失血量和更少的手术时间。因此,如果可以实现可接受的减少,则使用一种PFNA II固定是该损伤方式的不错选择。没有发现术中并发症。随访6个月后,X线摄片显示骨折正确对准并愈合良好。结论与两装置固定相比,用单一结构固定同侧股骨颈和干轴骨折具有良好的生物力学功能,最小的浸润,减少的失血量和更少的手术时间。因此,如果可以实现可接受的减少,则使用一种PFNA II固定是该损伤方式的不错选择。没有发现术中并发症。随访6个月后,X线摄片显示骨折正确对准并愈合良好。结论与两装置固定相比,用单一结构固定同侧股骨颈和干轴骨折具有良好的生物力学功能,最小的浸润,减少的失血量和更少的手术时间。因此,如果可以实现可接受的减少,则使用一种PFNA II固定是该损伤方式的不错选择。与两装置固定相比,手术时间更短。因此,如果可以实现可接受的减少,则使用一种PFNA II固定是该损伤方式的不错选择。与两装置固定相比,手术时间更短。因此,如果可以实现可接受的减少,则使用一种PFNA II固定是该损伤方式的不错选择。
