Abstract
Aims: We compared treatment with external fixation (EF) vs DHS in osteoporotic trochanteric fractures. Methods: 40 patients were randomized to receive either 135° 4-hole DHS (Group A) or an Orthofix trochanteric external fixator with 4 hydroxyapatite-coated Osteotite pins (Group B). Inclusion criteria were: female, age ≥65 years, AO fracture type A1-2 and BMD lower than -2.5T score. Fixators were removed at 3 months. Results: There were no differences in patient age, fracture type, BMD, ASA, hospital stay, or quality of reduction. Operative time was 64±6 minutes in Group A and 34±5 minutes in Group B (p< 0.005). Average number of blood transfusions was 2±0.1 in Group A, and none in Group B (p< 0.0001). Fracture varization at 6 months was 6±8° in Group A and 2±1° in Group B (p=0.002). Harris Hip Score was 62±20 in Group A and 63±17 in Group B (ns). In Group B, no pin-track infections occurred. Pin fixation was maintained over time, as shown by no differences between pin extraction and insertion torque. Conclusions: We consider EF a viable treatment option for this patient population. Operative time is short, postoperative complications are minimized, and fixation is improved.
