ABSTRACT
BACKGROUND:
Unstable femoral trochanteric fractures (FTFs), especially Arbeitsgemeinschaft für Osteosynthesefragen/ the Orthopedic Trauma Association (AO/OTA) 31-A2 fractures, which are multifragment fractures, occur in elderly individuals with osteoporosis and are associated with high mortality and complication rates due to prolonged immobilization. Longer nails (LNs) were developed to obtain superior fracture site stabilization in unstable FTFs. We hypothesized that the postoperative outcomes of elderly patients with unstable FTFs treated with LNs would be superior to those of patients treated with short nails (SNs), with fewer complications.METHODS:
This multicenter retrospective study aimed to compare the outcomes of SNs versus LNs in elderly patients with unstable FTFs. From the Trauma Research Group of our university (TRON) database, 1854 trochanteric fractures treated between January 2016 and December 2020 were extracted. A total of 174 patients>65 years of age with AO/OTA 31-A2 fractures were included in the present study. They were divided into the SN group and the LN group and matched for age and sex. Parameters such as operative time, blood loss, survival rate, Parker Mobility Score (PMS), and numerical rating scale (NRS) for pain, complications, and radiographic findings were analyzed.RESULTS:
Both groups included 67 patients with an average age of 87.32 years. The LN group had a longer operative time (76.52 min vs. 51.61 min, P < 0.001) and more blood loss (106.79 mL vs. 49.98 mL, P = 0.014) in comparison to the SN group. However, the 1-year survival rate, PMS, and NRS for pain did not differ to a statistically significant extent between the groups. The rates of complications, including screw cutout, nonunion, implant breakage, osteonecrosis of the femoral head, and surgical site infections, were comparable. The radiographic findings, including the nail/canal ratio, progression of varus, and sliding distance, were also similar.CONCLUSION:
Although LNs are associated with longer operative times and increased blood loss, the overall outcomes and complication rates are comparable to those of SNs in elderly patients with AO/OTA 31-A2 type unstable FTFs. The use of LNs did not confer any distinct advantages for this specific type of fracture.Palavras-chave
