Femur malunion treated with open osteotomy and intramedullary nailing in developing countries

Summary Introduction In developing countries, malunion, after diaphyseal femur fractures initially untreated by internal fixation, is not rare. Their difficult management contrasts with the deficiency of the technical operating room facilities. Patients and methods Our prospective study, conducted o...

Description
Summary:	Summary Introduction In developing countries, malunion, after diaphyseal femur fractures initially untreated by internal fixation, is not rare. Their difficult management contrasts with the deficiency of the technical operating room facilities. Patients and methods Our prospective study, conducted over a 1-year period, reports 16 open osteotomies fixed using Küntscher intramedullary nailing in patients who presented malunion of the femoral diaphysis. Twelve males and four females (mean age, 34.5 years; range, 18–67 years) were managed with a mean time to surgery of 8 months (range, 4–14 months). All had initially consulted a bonesetter. The mean length inequality was 3 cm (range, 2–6 cm); the mean knee flexion limitation was 90° (range, 10°–120°). Locking of the rotation was obtained by the obliquity of the osteotomy line. No bone filling was added but reaming and decortications were systematic. The patients were clinically and radiographically assessed at D21, D45, D90, and D120, based on the evaluation of the length inequality, mobility, and bone union. Rotational malunion or deformity were not analyzed. Results Fifteen patients had achieved union in 90 days. In one case, secondary incurvation of the nail led to changing the nail, allowing union with no axis deformity at D120. The mean postoperative knee flexion was 120° (range, 45°–130°). The mean gain in length was 2 cm (range, 1.5–4 cm). Discussion This open technique using non-interlocking material allowed us to obtain bone union while improving joint mobility and length inequality. Level of evidence Level IV. Retrospective study.
