Ipsilateral Neck/Inter-Trochanteric and Mid-shaft Femoral Fractures Treated with Dual Construct Implants

Abstract

Background: Various management protocols for ipsilateral neck/intertrochanteric and shaft fracture femur have been formulated, there have been many disagreements related to their ideal fixation plan. The aim of this study was to discuss the various type of fixation system available for such kind of complex injuries and the advantages of using dual construct fixation system. Patient and Methods: In the present study we prospectively evaluated ipsilateral neck/intertrochanteric and shaft fracture femur in 7 cases managed from January 2018 to December 2020. All the patients were managed with dual constructs fixation system using dynamic hip screw (DHS) and locking plate. The outcome was evaluated using Friedman and Wyman scoring system. Results: The average surgical time was 120.4 min (range 98–143 minutes) with a blood loss ranging from 290-565 mL (average 460 mL). In 6 patients follow-up was undertaken between 10 and 22-months after surgery, with a mean follow-up time of 16.2 months. 1 patient lost follow-up at 3-month. The neck/IT fractures achieved union in 6 patients at the final follow-up. 3-6 months was the duration for bone union, with an average of 4.1 months. The mid-shaft femur fractures achieved solid union in 6 cases at the most recent follow-up. 3 to 11 months was the duration of union, with a mean of 5.1 months. 1 patient went into non-union 11 months after the surgery.  According to Friedman and Wyman scoring, 4 patients the functional outcome was good, in 2 patients the functional outcome was fair, and in 1 patient the functional outcome at the final follow-up was poor. The problems noted were surgical site infection in 1, Angulations (varus/valgus) of femoral neck in 1, non-union of neck femur fracture in 1, and avascular necrosis of femoral head in 1. Conclusion: The management of ipsilateral neck/intertrochanteric and shaft fracture femur with dual construct implants dynamic hip screw for neck/IT fracture and locking plate for shaft femoral fractures yielded good union rates and good functional outcomes.
