Intramedullary nailing of tibial non-unions using the suprapatellar approach: a case series

Botma, Nicolaas 08 February 2022 (has links)
Background: A number of treatment options are available for diaphyseal non-unions of the tibia, including intramedullary (IM) nailing. An infrapatellar entry point with the knee in deep flexion can make this procedure challenging, especially with associated deformity or an obliterated canal. The suprapatellar approach allows nail insertion with the knee extended, which facilitates correction of malalignment in the sagittal and coronal planes. The aim of our study was to review the outcome of diaphyseal tibia non-unions, treated with an intramedullary nail, using the suprapatellar approach. Method: We retrospectively reviewed consecutive cases with non-union of the tibial shaft, treated with a suprapatellar entry nail between May 2016 and January 2018. Patients who were previously managed with a nail or who had active sepsis were excluded. The rate and time to union, as well as complications were assessed. Results: Thirteen cases were included and followed up until union at a mean of 5.8 months. All were performed percutaneously, without opening of the non-union site. Two patients developed complications, although bony union was still achieved. Conclusion: A suprapatellar entry tibial nail is an acceptable treatment option for tibial non-unions not previously treated with a nail.

Landmarkenanalyse zur Implantation der Tibia-Komponente einer LCS® Knie-Totalendoprothese unter Nutzung einer kernspintomographischen 3D-Bild-Analyse / Landmark analysis for the implantation of the tibial component of the LCS total knee system® using MRI-3D analysis

Sakaki, Akio January 2011 (has links) (PDF)
Diese prospektive radiologisch-klinische Studie vergleicht die Eignung dreier anatomischer Strukturen (Sehne des M. tibialis ant., Tibiavorderkante und Intermetatarsal-raum I) als intraoperative Landmarke bei der Implantation der Tibia-Komponente eines bikondylären Oberflächenersatzes mit einer mobilen Gleitlage. Eine möglichst genaue mechanische Achsausrichtung trägt laut Fachliteratur nicht nur zur langen Standzeit des Implantats bei, sondern führt auch zu einer früheren Rehabilitation und somit zu besserer klinischer Funktion des operierten Knies. Im Rahmen der Studie wurden insgesamt 29 Patienten rekrutiert, die zur Implantation einer LCS® Prothese (DePuy, Warsawa, USA) anstanden. Das Studiendesign beinhaltete eine präoperative Body Mass Index und Knee Score Bestimmung, eine Ganzbeinstandaufnahme und eine 3D-MRT-Bildanalyse. Die präoperative Achseinteilung ergab einen Varuswinkel (Tibiofemoral-Winkel <3 Grad) bei 16 Patienten, einen physikalischen Winkel bei neun Patienten und einen Valguswinkel bei vier Patienten. In der 3D-Bildanalyse wurde die Lage der drei oben genannten Strukturen zu einer virtuellen kernspintomographisch darstellbaren mechanischen Achse verglichen. Diese Analyse zeigt, dass die Sehne des M. tibialis ant. im Mittel die ideale Implantationsachse am ehesten reflektiert (Abstand zur idealen Achse: -1,66 +/-5,73mm), gefolgt von der Tibiavorderkante (-1,87 +/-2,58mm; p=0,859) und dem Intermetatarsalraum I (3,01 +/-8,48mm; p= 0,006). Insgesamt weist die Sehne des M. tibialis ant. die besten Eigenschaften als Landmarke auf, da sie den durchschnittlich kleinsten Abstand zur idealen Implantationsachse bei vergleichsweise geringer Streuung und hoher Intra-Beobachter-Reliabilität zeigt. Eine Ausnahme bilden Patienten mit starker Varusstellung in der präoperativen Beinachse. Die differenzierte Analyse in Abhängigkeit der präoperativen Beinachse legt nahe, dass hier die Tibiavorderkante aufgrund ihrer geringen Streuung im Abstand zur idealen Implantationsachse als Landmarke vorzuziehen ist, obwohl sie eine niedrigere Intra-Beobachter-Reliabilität als die Sehne des M. tibialis ant. hat. / This prospective radiological-clinical study compares the suitability of three anatomical structures as intraoperative landmarks for the implantation of the tibial component in total knee replacement using bicondylar knee prosthesis with a mobile bearing system: Tendon of the tibialis anterior muscle, anterior edge of the tibia, first intermetatarsal space. According to previous research, a high level of precision in the reconstruction of mechanical alignment will not only contribute to a long life span of the implant, but also enable a quicker rehabilitation and thus a better clinical function of the prosthesis. In this research project, 29 patients awaiting treatment by total knee arthroplasty using the LCS Mobile-Bearing Knee System®, were recruited. In the course of the study, the following data was collected: a preoperative body mass index, clinical knee score, X-Ray a.p. lateral view single leg with patient standing and 3D-MRI analysis of the lower extremity. The recruited patients were then divided into three subgroups for statistical analysis according to their preoperative anatomical alignment: 16 patients with varus knees, 9 patients with physiological knees, 4 patients with valgus knees. In the 3D-MRI analysis, the positions of the three anatomical structures named above were compared to a virtually reconstructed mechanical axis. The analysis demonstrates that the position of the tendon of the tibialis anterior muscle reflects most closely the ideal implantation axis (Distance to mechanical axis: -1,66 +/-5,73mm), followed by the anterior edge of the tibia (-1,87 +/-2,58mm; p=0,859) and the first intermetatarsal space (3,01 +/-8,48mm; p= 0,006). The study concludes that the tendon of tibialis anterior muscle should be considered the best suitable structure of implantation of the tibial component. This is because it is characterized by the shortest mean distance from the mechanical axis, the least spread in the statistical data and high intra-observer reliability. However, the subgroup of patients with distinct varus deformity appears to be an exception. The differentiated analysis that takes the preoperative anatomical alignment into account reveals that the anterior edge of the tibia may be better suited as intraoperative landmark. This structure offers a low spread for this patient group, although its intra-observer reliability is lower than that of the tendon of the tibialis anterior muscle.

Franco Cortéz, Carlos Modesto January 2005 (has links)
Las fracturas diafisiarias de tibia, son de las lesiones mas frecuentes en traumatología, siendo una de sus principales causas los accidentes de transito: choques, atropellos; violencia física caídas, accidentes deportivos entre otras causas. Se revisaron todas las Historias Clínicas de pacientes que ingresaron al Hospital Sergio E. Bernales con el Diagnostico de fracturas diafisiarias de tibia, un total de 76 Historias Clínicas, de las cuales 42 fueron seleccionadas para el presente trabajo por tener los criterios de inclusión, información completa y que fueron sometidos a intervención quirúrgica con el Sistema de Fijación Externa Descartable. La fijación externa es una opción mas, entre tantas otras posibilidades quirúrgicas, es ampliamente aceptada para fracturas expuestas como la primera opción, sin embargo para fracturas cerradas la bibliografía menciona otras posibilidades quirúrgicas como son el Clavo Intramedular, placas y tornillos según sea el caso. En el presente estudio, de 42 pacientes, 36 fueron hombres (85.71%), el promedio de edad de 20 – 29 años con 15 pacientes con un 35.71 % , el mecanismo de acción (atropello) 26 pacientes (61.9%), la tibia derecha se afecto en 27 pacientes (64.28%), fracturas cerradas 24 pacientes (57.14%), las fracturas tipo II de Aybar 15 pacientes (35.71%)fueron las mas frecuentes, se realizaron fasciotomia en 11 pacientes (26.19%), osteosintesis mínima en 15 pacientes (35.51%), el tiempo de consolidación vario de 6 – 15 meses, las tipo I de Aybar consolido en 8.57 meses.
