Anterior instrumented fusion is at least as efficient as the posterior procedure in the management of cervical spine injuries and it also has several advantages. Most of such injuries, including the dislocations, can be managed with anterior instrumented fusion alone. Simple means of immobilization such as the hard collar suffice, and secondary posterior fixation is rarely, if ever, necessary.
In spite of increased understanding of biomechanics and improvements of implant design, nonunion of femoral shaft fractures continues to hinder the treatment of these injuries. Femoral nonunion presents a difficult treatment challenge for the surgeon and a formidable personal and economic hardship for the patient. In most series of femoral fractures treated with intramedullary nailing techniques, the incidence of this complication is estimated to be 1%. A higher frequency has recently been reported due to advances in trauma care leading to increased survivorship among severely injured patients and expanded indications of intramedullary nailing. Whereas the treatment of femoral shaft fractures has been extensively described in the orthopedic literature, the data regarding treatment of femoral shaft nonunions are sparse and conflicting, as most of the reported series consisted of a small number of cases. However, careful review of the existing literature does provide some answers regarding either conservative or operative management. The gold standard for femoral shaft nonunions invariably includes surgical intervention in the form of closed reamed intramedullary nailing or exchange nailing, but several alternative methods have been reported including electromagnetic fields, low-intensity ultrasound, extracorporeal shock wave therapy, external fixators and exchange or indirect plate osteosynthesis. In this paper, a comprehensive review of the current treatment modalities for aseptic midshaft femoral nonunion is presented, after a concise overview of the incidence, definition, classification and risk factors of this complication.
We reviewed 18 patients, 14 with acute fractures and four with non-union of the distal tibia, treated between 1990 and 2001 with a shortened, reamed intramedullary nail. The mean follow-up was 38 (8-144) months. The fractures united at an average of 16 (12-18) weeks and the non-unions at 20 (12-30) weeks. Two patients required nail dynamization. No limb shortening nor material failures were seen. All patients returned to normal daily activities. Although technically demanding, intramedullary nailing for distal tibial fractures and nonunions with a shortened nail represents a safe and reliable method.Résumé Nous avons revus 18 malades, 14 avec une fracture récente et quatre avec une pseudarthrose tibial distale, traité entre 1990 et 2001 avec un clou intramé-dullaire court placé après alésage. Le suivi moyen était de 38 mois (8-144) . Les fractures ont consolidé à une moyenne de 16 (12-18) semaines et les pseudarthroses à 20 (12-30) semaines. Deux malades ont nécessité une dynamisation du clou. Il n'y a pas eu de raccourcissement de membre ni d'ennuis de matériel. Tous les malades ont retrouvé des activités journalières normales. Bien que difficile techniquement, l'enclouage intramédullaire distal avec un clou court représente une méthode sûre et fiable.
Treatment of pertrochanteric fractures using the TGN and PFN implants is quite reliable. The major complication was cut-out and occurred mostly in the PFN group, while varus deformity was more frequent in the TGN group. The PFN was associated with a higher rate of reoperation and longer operative time, probably due to a more demanding technique.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
