Background: The proximal femoral fracture is one of the most common injuries in the elderly. Nevertheless, no results beyond the second year post surgery have been reported in the literature. Therefore, the purpose of this study was to evaluate any revision and mortality within 10 years follow-up as well as the walking ability of still alive patients. Methods: A total of 200 consecutive patients were included. A prospective database was first used to collect the demographic data. Exactly ten years after the surgery, a final evaluation was conducted by telephone for every patient. Any revision, any contralateral as well as other fractures and the date of death were recorded. For all patients who were still alive, the mobility score according to Parker was also surveyed. Results: The average age was 79.0 years (SD: 12.5); women were affected at higher numbers (73.5%). The total surgical revision rate was 17.5% (35/200), due in particular to hematoma (9x) or infection (7x). A surgical revision later than two years was only needed in three patients (1.5%). The risk of another fracture caused by a fall was 19% (38/200), most often a contralateral femoral fracture (22/200; 11%) that happened on average 51.9 months (1-97) after the initial surgery. The risk of a contralateral femoral fracture was 15.4% (22/143) in patients who survived the first year post surgery. The postoperative mortality was 1, 2, 5 and 10 years or 23.5%, 32.5%, 55% as well as 81.5%, respectively. An average Parker's mobility score of 6.3 points (0-9) was determined for the 37 patients (18.5%) who were still alive at the time of the follow-up. Conclusion: The long-term study showed that revision surgery was only required in 3/200 patients (1.5%) beyond the second year of that surgery. On the other hand, more than half of all patients had already passed away five years after the initial surgery. The exact incidence of a contralateral femoral fracture was 11.9%, climbing to 15.4% if the patient survived at least one year. Nearly every fifth patient experienced another fall resulting in a severe fracture requiring treatment during the long-term course. (c) 2018 Elsevier Ltd. All rights reserved.

Introduction Information is lacking regarding incidence rates, treatment regimens, and outcomes concerning peri-implant femoral fractures (PIF). Therefore, we performed a retrospective study to provide scientific data concerning incidence and outcome of PIF following osteosynthesis of proximal femoral fractures (PFF). Material and methods We retrospectively included all patients who received osteosynthesis for PFF between 2006 and 2015 and in whom PIF was confirmed postoperatively. All available patients with PIF were contacted minimum one year post-surgery. Results A total of 1314 osteosynthesis procedures were performed, of which 705 were proximal femoral nails (PFNs), 597 were dynamic hip screws (DHSs), and 12 were screws appliances only. During the same period, 18 PIFs (1.4%) were reported. However, PIF was 3.7 times higher within PFN when compared to DHS (15/705:2.1% versus 3/597:0.5%; odds ratio: 3.7). The following analysis also included 8 patients with PIF who were referred from other hospitals, resulting in a total of 26 patients. Mean patient age was 84.8 years (range, 57–95), with a predominance in female (23×) and in the left femur (19×). PIF occurred after an average of 23.6 months (range, 1–81) post-surgery. The fractures, most of which were spiral-shaped, were most commonly treated with locking plate osteosynthesis. The surgical revision rate was 7.7%, and the one-year mortality was 23.1%. At an average of 43.0 months (range, 12–100) post-surgery, it was possible to contact 18/26 patients (69.2%), and their mean Parker Mobility Score was 5.2 points (range 2–9). Conclusions Peri-implant femoral fracture is a rare incident within the old age traumatology of PFF. However, based on our small number of cases, it occurred within PFN much more frequently compared with DHS. Locking plate osteosynthesis has been shown to be effective and reliable. Surgical revision and mortality rates do not appear to be increased when compared to those with the initial treatment of proximal femoral fractures.

INTRODUCTION: To date, there is a lack of valid data with larger populations of patients in their 10th decade of life in the analyses of proximal femoral fractures. MATERIAL AND METHODS: The inclusion criteria focused on all proximal femoral fractures in patients 90-99 years of age who underwent surgical treatment between 2009 and 2012. After a period of at least 2 years post-surgery, a retrospective collection of empiric data, including the survival time and surgical revision rate, was performed. Missing data were collected per telephone interview. RESULTS: A total of 121 proximal femoral fractures in 117 patients in their 10th decade of life were treated. The mean age was 92.3 years. 61 fractures of the femoral neck received hemi- or total hip arthroplasty, while 60 pertrochanteric or subtrochanteric fractures were treated by osteosynthesis using proximal femoral nail (PFN) or dynamic hip screw (DHS). At the time of follow-up, 83/117 patients (71%) were already deceased. The mortality after 30 days, 6 months, 1 year and 2 years was 16%, 37%, and 43%, and 55%, respectively. A total of 22 surgical revisions (19%) were performed: 10 due to early infections, 8 due to haematomas, and 4 due to implant failures with a "cut out" of the femoral neck screw exclusively in DHS. The duration of surgery (with regard to surgical revision) and ASA classification (with regard to survival rate) were significant influence factors. Contralateral proximal femoral fractures were identified in 24/117 patients (20%), irrespective of study period. CONCLUSIONS: The proximal femoral fractures in the 10th decade of life are associated with high postoperative mortality within the first 6 months. Surgical revision due to complications did not result in a statistically significant reduction of the survival time. From the osteosynthetic perspective, the DHS was associated with a significantly higher "cut-out" rate compared to PFN procedure. With regard to the alloarthoplasty, there were no significant differences observed between hemi- and total hip arthroplasty. A contralateral femoral fractures was observed in 20% of the total study population, but peri-implant or periprosthetic femoral fractures have not been observed in any of the cases thus far.
