          Abstract

          Resumen Introducción: La indicación de realizar una osteosíntesis con un clavo endomedular retrógrado en las fracturas de fémur se ha incrementado en los últimos años y, con ello, la cantidad de complicaciones. Se describen tres técnicas quirúrgicas para el manejo del fragmento proximal de la osteosíntesis endomedular rota. Desde marzo de 2001 hasta enero de 2019, se realizaron 321 osteosíntesis con clavos endomedulares retrógrados de fémur en nuestra institución. La tasa de rotura del implante asociada a una seudoartrosis fue del 0,9%. Se realizaron técnicas mínimamente invasivas para la extracción del implante, preservando las partes blandas. Se logró la reosteosíntesis definitiva con la consiguiente consolidación en un tiempo medio de 140 días. Conclusiones: Las técnicas utilizadas fueron simples, seguras, mínimamente invasivas y muy reproducibles.

          Abstract Background: The indication for osteosynthesis with a retrograde intramedullary nail in femur fractures has increased in recent years and with it, the number of complications. Three surgical techniques are described for the management of the proximal fragment of the broken intramedullary osteosynthesis. From March 2001 to January 2019, 321 osteosyntheses with retrograde femoral intramedullary nails were performed at our institution. The implant rupture rate associated with nonunion was 0.9%. Minimally invasive techniques were performed to remove the implant, preserving the soft tissues. Definitive reosteosynthesis was achieved with the consequent consolidation in an average time of 140 days. Conclusions: The techniques used were simple, safe, minimally invasive, and reproducible.

          Closed intramedullary nailing of femoral fractures. A report of five hundred and twenty cases.

          Intramedullary nailing was performed on 520 femoral fractures in 500 patients. The series included eighty-six open fractures and 261 comminuted fractures. Closed intramedullary nailing was used in 497 femora and open intramedullary nailing with cerclage wiring, in twenty-three. The union rate was 99.1 per cent. The range of motion of the knee at follow-up averaged 130 degrees. Complications included four infections (0.9 per cent). Shortening of more than two centimeters occurred in ten patients (2.0 per cent) and malrotation of more than 20 degrees was observed in twelve patients (2.3 per cent). After prompt emergency measures had been taken, routine treatment included strong preoperative traction followed by accurate positioning of the patient on the operating table; selection of the correct insertion point for a properly sized, prebent, flexible, bullet-tipped nail; and accurate reduction of the fracture. Careful rehabilitation of the patient also contributed to the excellence of the results.

            Removal of broken hardware.

            Despite advances in metallurgy, fatigue failure of hardware is common when a fracture fails to heal. Revision procedures can be difficult, usually requiring removal of intact or broken hardware. Several different methods may need to be attempted to successfully remove intact or broken hardware. Broken intramedullary nail cross-locking screws may be advanced out by impacting with a Steinmann pin. Broken open-section (Küntscher type) intramedullary nails may be removed using a hook. Closed-section cannulated intramedullary nails require additional techniques, such as the use of guidewires or commercially available extraction tools. Removal of broken solid nails requires use of a commercial ratchet grip extractor or a bone window to directly impact the broken segment. Screw extractors, trephines, and extraction bolts are useful for removing stripped or broken screws. Cold-welded screws and plates can complicate removal of locked implants and require the use of carbide drills or high-speed metal cutting tools. Hardware removal can be a time-consuming process, and no single technique is uniformly successful.

              Broken intramedullary nails.

              Between 1962 and 1987, we treated fifty-six patients for sixty broken intramedullary nails, using a custom-made hook to extract the distal fragment of the nail. The charts and radiographs of all of the patients were reviewed. Thirty-nine of the nails had been inserted in a fresh fracture, which usually was comminuted; eight had been used for fixation of an osteotomy; nine, for fixation of a non-union; and four, for treatment of a pathological fracture. Several small-diameter intramedullary nails broke at the site of the fracture or non-union. In contrast, the sites of breakage in the interlocking nails were the interlocking holes and the welded junction of the top insertional portion and the proximal slot. Many of the breakages were in patients who had an unstable fracture pattern. The interval between insertion and breakage ranged from one to 120 months.
