Ipsilateral basicervical femoral neck and shaft fractures treated with long proximal femoral nail antirotation or various plate combinations: comparative study

Although many treatment methods have been developed, controversy exists regarding the optimal management of ipsilateral femoral neck and shaft fractures. The purpose of this retrospective study was to compare the results of long proximal femoral nail antirotation (PFNA-long) and various plate combinations in the treatment of ipsilateral basicervical femoral neck and shaft fractures. Between January 2004 and May 2008, a total of 21 patients with ipsilateral basicervical femoral neck and shaft fractures were treated with PFNA-long or various plate combinations. We divided patients into two groups. Group I included 11 patients who underwent surgery with cancellous lag screws or dynamic hip screws (DHS) combined with compression plate fixation. Group II included 10 patients who underwent surgery with PFNA-long. The average follow-up periods were 22.2 and 20.8 months for groups I and II, respectively. The average union times for femoral neck fractures in groups I and II were 15.6 and 16.0 weeks, respectively; and the average union times for shaft fractures were 21.1 and 20.3 weeks, respectively. There were eight good, two fair, and one poor functional result in group I and eight good, one fair, and one poor in group II. One case of implant failure and nonunion of the femoral shaft fracture occurred in group I. There were no significant differences in the functional outcomes or major complications between the two groups. Both treatment methods achieved satisfactory functional outcomes in patients with ipsilateral basicervical femoral neck and shaft fractures. PFNA-long was a good option for the treatment of complex fractures, with the advantages of closed antegrade nailing with minimal exposure, reduced perioperative blood loss, and biological fixation of both fractures with a single implant.
