Outcomes of minimally invasive osteosynthesis of intertrochanteric fractures with dynamic hip screw: A prospective case series

Abstract

BackgroundIntertrochanteric fractures are a public health concern, especially in geriatric patients. Early surgical management is crucial to allow early mobilization, which helps reduce the disability and increase patients' survival. In this article, we report the outcomes of minimally invasive osteosynthesis of intertrochanteric fractures with dynamic hip screw (DHS). MethodsThe present study was a prospective case series of patients who had intertrochanteric fractures treated with minimally invasive DHS technique. Postoperative patient satisfaction rate was evaluated using the visual analog scale (VAS) of pain. Functional outcomes were evaluated using the Harris hip score (HHS) and the Merle-d'Aubigne-Postel (MDP) scoring system at 12 months of follow-up. Satisfactory results were considered with HHS of ≥80 points and MDP scores of ≥15. Postoperative complications were noted. ResultsIn this study, 70 patients were included, 41 (58.6%) males and 29 (41.4%) females, with an average age of 69.3 ± 8.3 years. The mean length of hospital stay was 2.1 ± 0.9 days. The average follow-up period was 23.9 ± 7.1 months. The mean time to radiological union was 16.8 ± 1.9 weeks. The mean postoperative VAS score for pain was 2.5 ± 1.1. The mean HHS was 87.1 ± 4.7 points and the mean MDP score was 15.6 ± 2.3 at 12 months follow-up. An average of 10.6 ± 2.9 weeks was required for full weight bearing. ConclusionThe minimally invasive DHS technique effectively treats intertrochanteric fractures with minimal incision, less bleeding, shorter operative time, early discharge from hospital, faster rehabilitation, and favorable functional outcomes.
