Abstract
Purpose: Unstable intertrochanteric (IT) fractures are common orthopedic injuries in the elderly people with high morbidity. The treatment of unstable IT fractures with sliding hip screw (SHS) is still controversial. The purpose of our study is to assess the outcomes of conventional SHS in unstable IT fractures in comparison to stable ones.
Methods: A total of 35 stable and 23 unstable IT fracture cases were treated with SHS between January 2017 and December 2018. Patients were evaluated for infection, revision rate, screw cut-out, development of post-traumatic arthritis or heterotopic ossification, and mortality.
Results: The mean age of the patients at the time of surgery was 69.8 and 73.9 years for stable and unstable IT fractures, respectively, with 38 males (25 stable vs. 13 unstable) and 20 females (10 in each group). The mean follow-up was 42.2 and 49.4 weeks in stable and unstable IT fractures, respectively. We found a significant association between the occurrence of screw cut-out in unstable fractures compared to stable ones (17.4% vs. 0%, respectively, p = 0.01). There was an obvious trend for nonunion and higher revision rates in unstable IT fractures (17.4% vs. 2.9%, p = 0.056). Logistic regression analysis did not reveal any statistically significant confounder that might affect the rates of fracture union or revision rates. Post-traumatic arthritis and heterotopic ossification occurred in one case of unstable IT fracture. There were no reported cases of infection.
Conclusion: There are higher risks of screw cut-out, nonunion, and the need for revision when the SHS is used to treat unstable IT fractures.
