Double-plate compound osteosynthesis for pathological fractures of the proximal femur: high survivorship and low complication rate	Merckaert et al.	Archives of Orthopaedic and Trauma Surgery	2019	IV	n = 61 Mean age: 63.5 Range of age: 39.6–92.7	n = 46 double-plate compound osteosynthesis n = 15a double-plate compound osteosynthesis was performed as revision procedure	22 (2.4–306)	Construct survival rates of 96% at 6 months, and 90% thereafter for primary reconstructions Comparing the calculated survivorship with the literature, it is evident that double-plate compound osteosynthesis is superior to simple open reduction and internal fixation with or without cement augmentation, intramedullary nailing and comparable if not higher than endoprosthetic replacement	The mean Merle d’Aubigné score was 14 ± 7 (range 3–17), at 0–3 months, 13 ± 3 (7–18), at 3–6 months, 15 ± 3 (9–18), at 6–12 months and 15 ± 4 (8–18) thereafter
Compound osteosynthesis for osteolyses and pathological fractures of the proximal femur	Kinkel et al.		2009	IV	n = 34 n.a n.a	n = 34 n = 22 double-plate compound osteosyntheses n = 12 single-plate compound osteosyntheses	n.a	Survival time after compound osteosynthesis was 14.2 months (range 0–72 months) Double-plate compound osteosyntheses showed a lower mechanical failure rate than single-plate compound osteosyntheses (14.3% vs 33.3%) and a higher survival probability after 5 years (76.4% vs 38.6%) No surgical revision was required due to perioperative complications in any case	n.a
