ABSTRACT
Las fracturas del extremo distal de fémur constituyen un grupo de lesiones de difícil manejo, cuyos resultados no son uniformemente buenos y cuyo tratamiento y recuperación requiere un considerable esfuerzo por parte del traumatólogo y del paciente. Su tratamiento a sufrido modificaciones considerables. El objetivo de este trabajo es describir la experiencia de nuestro centro en el manejo de las fracturas supracondileas de fémur. Se revisaron 76 historias con diagnostico de fractura supracondilea de fémur en el Hospital Central del IVSS Dr. Miguel Pérez Carreño, en el periodo comprendido de 2004 a 2008; de los cuales 87% son masculinos y 13% femenino, en una edad comprendida entre 10 a 76 años con una promedio de 35 años, el mecanismo de lesión mas frecuente fue heridas por arma de fuego con 37 casos (49%), las fracturas abiertas correspondieron a las tipo III A (69%). En 36 casos se observó un trazo de fractura metafisiario a causa de heridas por arma de fuego, con 47 días de hospitalización en promedio. El 58% de los pacientes recibió tratamiento quirúrgico, entre ellos DCS (48%), clavos endomedulares bloqueados (14%), placas anatómicas dístales de fémur (11%) y tutores en 4 casos, los clavos bloqueados retrógrados se colocaron a 3 pacientes. El 42% recibieron tratamiento conservador con yeso inguinopédico. Como complicaciones se reportaron pseudoartrosis en el 7%; rigidez articular 9% asociado con tornillos canulados, consolidación viciosa en un 25% y acortamiento de 5 cm en promedio de 13% (4 casos) asociado a tratamiento conservador. En cualquier caso el tipo de tratamiento, sea conservador o quirúrgico, requiere una previa valoración cuidadosa de la anatomía de la fractura y de la situación global del paciente.
Fractures of the distal femur are a group of injuries are difficult to manage, the results are not uniformly good and which treatment and recovery requires a considerable effort by the orthopedist and the patient. His treatment has undergone significant changes. The aim of this study is to describe our experience in the management of supracondylar fractures of the femur. 76 stories were revised diagnosis of supracondylar fracture of femur in the Central Hospital Dr. Miguel Perez Carreño IVSS in the period from 2004 to 2008, of whom 87% are male and 13% female, at an age between 10 to 76 years with an average of 35 years, the most frequent mechanism of injury was gunshot wounds in 37 cases (49%), open fractures corresponded to type III (69%). In 36 cases showed a metaphyseal fracture line due to gunshot wounds, with 47 days of hospitalization on average. 58% of the patients received surgical treatment, including DCS (48%), locked intramedullary nails (14%), distal femur anatomical plates (11%) and mentors in 4 cases, blocked retrograde nails were placed in 3 patients . 42% received conservative treatment with plaster inguinopédico. Complications included nonunion reported in 7% 9% joint stiffness associated with cannulated screws, malunion in 25% and shortening of 5 cm on average 13% (4 cases) associated with conservative treatment. In any case the type of treatment, whether conservative or surgical, requires prior careful assessment of the anatomy of the fracture and the overall situation of the patient.

PURPOSE: To analyze the midterm results of the treatment with a retrograde nail for periprosthetic fractures of the femur following total knee arthroplasty. MATERIALS AND METHODS: Between Jan 1998 and Jan 2004, 11 cases in 11 patients were treated for the periprosthetic fractures following total knee arthroplasty. The mean follow-up was 42.0 (30~98) months and the mean age was 66.0 (57~79) years old. 2 were males and 9 patients were females. In all cases, retrograde nailing was done for the periprosthetic fractures. Postoperative range of motion, HSS knee rating score, femorotibial angle, the time required for union, complications were evaluated. RESULTS: Postoperative range of motion was 103.6° degrees on an average, HSS knee rating score was 83.5 points on an average at the last follow up. The mean angulation on radiograph was valgus 6.3°. The mean time required for union was 4 months. One had a newly fracture line at proximal part of supracondylar fracture, but there was no significant in clinical course. There was no prostheses required revision. CONCLUSION: It appears that retrograde nail is a reliable surgical technique for periprosthetic fractures of the femur following total knee arthroplasty with low complication rate. The midterm results in our study showed that none of the prostheses required revision.
