A prospective study is presented of 87 unstable intertrochanteric fractures treated with the proximal femoral nail anti-rotation (PFNA) with a follow-up of one year. Of the patients 76% were female. The average age was 75.3 years. The fracture was treated by closed reduction and intramedullary fixation. Pre-injury activity level was recovered in 77% of the patients. Fractures united in all patients. Mechanical failure and cut-out were not observed. A technical problem related to the mismatch of the proximal end of the nail was observed in 11 cases. Nine patients presented with thigh pain due to the redundant proximal end of the nail. The results of the PFNA were satisfactory in most elderly Chinese patients. However, the proximal end of the nail was not matched with the specific anatomy of some short elderly patients. Further modifications of the nail are necessary for the elderly Chinese population.
本文呈现了一项前瞻性研究,对87例采用股骨近端抗旋髓内钉(PFNA)治疗的不稳定型股骨转子间骨折患者进行了为期一年的随访。患者中76%为女性。平均年龄为75.3岁。骨折采用闭合复位髓内固定治疗。77%的患者伤前活动水平得以恢复。所有患者骨折均愈合。未观察到机械性失败和内固定物穿出情况。11例患者观察到与髓内钉近端不匹配相关的技术问题。9例患者因髓内钉近端多余而出现大腿疼痛。PFNA的治疗结果在大多数中国老年患者中令人满意。然而,髓内钉近端与一些身材矮小的老年患者的特定解剖结构不匹配。对于中国老年人群,有必要对髓内钉进行进一步改良。
